<p id="isPasted">Holographic images have real depth because they are three dimensional, whereas monitors merely simulate depth on a 2D screen. Because we see in three dimensions, holographic images could be integrated seamlessly into our normal view of the everyday world.</p><p>The result is a virtual and augmented reality display that has the potential to be truly immersive, the kind where you can move your head normally and never lose the holographic images from view. “To get a similar experience using a monitor, you would need to sit right in front of a cinema screen,” said <a href="https://engineering.princeton.edu/faculty/felix-heide" target="_blank">Felix Heide</a>, assistant professor of <a href="http://cs.princeton.edu/" target="_blank">computer science</a> and senior author on <a href="https://www.nature.com/articles/s41467-024-46915-3" target="_blank">a paper</a> published April 22 in Nature Communications.</p><p>And you wouldn’t need to wear a screen in front of your eyes to get this immersive experience. Optical elements required to create these images are tiny and could potentially fit on a regular pair of glasses. Virtual reality displays that use a monitor, as current displays do, require a full headset. And they tend to be bulky because they need to accommodate a screen and the hardware necessary to operate it.</p><p>“Holography could make virtual and augmented reality displays easily usable, wearable, and ultrathin,” said Heide. They could transform how we interact with our environments, everything from getting directions while driving, to monitoring a patient during surgery, to accessing plumbing instructions while doing a home repair.</p><p>One of the most important challenges is quality. Holographic images are created by a small chip-like device called a spatial light modulator. Until now, these modulators could only create images that are either small and clear or large and fuzzy. This tradeoff between image size and clarity results in a narrow field of view, too narrow to give the user an immersive experience. “If you look towards the corners of the display, the whole image may disappear,” said Nathan Matsuda, research scientist at Meta and co-author on the paper.</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 790px;"><span class="fr-img-wrap"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713912832170-Neural_Etendue_Expander_3_v2-1-2048x1152.png" style="width: 100%px;" class="fr-fic fr-dib"><span class="fr-inner">At left, an image produced using current holographic display technology.

Along with their collaborators, they built a second optical element to work in tandem with the spatial light modulator. Their device filters the light from the spatial light modulator to expand the field of view while preserving the stability and fidelity of the image. It creates a larger image with only a minimal drop in quality.</p><p>Image quality has been a core challenge preventing the practical applications of holographic displays, said Matsuda. “The research brings us one step closer to resolving this challenge,” he said.</p><p>The new optical element is like a very small custom-built piece of frosted glass, said Heide. The pattern etched into the frosted glass is the key. Designed using AI and optical techniques, the etched surface scatters light created by the spatial light modulator in a very precise way, pushing some elements of an image into frequency bands that are not easily perceived by the human eye. This improves the quality of the holographic image and expands the field of view.</p><p>Still, hurdles to making a working holographic display remain. The image quality isn’t yet perfect, said Heide, and the fabrication process for the optical elements needs to be improved. “A lot of technology has to come together to make this feasible,” said Heide. “But this research shows a path forward.”</p><p><em>The paper, “Neural Etendue Expander for Ultra-Wide-Angle High-Fidelity Holographic Display” was published April 22 in Nature Communications.

<p id="isPasted">As augmented and mixed reality experiences become more popular through various devices, advancements in battery technologies are needed to ensure that these crucial components are made smaller, yet maintain their functionality. One <a href="https://www.mse.engineering.cmu.edu/index.html" rel="noopener" target="_blank">Department of Materials Science and Engineering</a> alumnus is involved with developing the technologies needed to bring these products to market at Meta.</p><p>As a battery system engineer, Ankur Gupta, BS’10, MS’10, takes an interdisciplinary approach rooted in his studies at CMU to working with the multiple teams of engineers involved in the development of devices such as the Quest 3 and Ray-Ban | Meta smart glasses.</p><p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzA4MDk3Njk5MzE2LTAyMDktZW0tZnV0dXJlLXZpc2lvbi5wbmciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 300px;" class="fr-fic fr-dib"></p><p id="isPasted">At one end of the spectrum, he works with cell engineers, often chemical and materials science engineers, who design the chemistry inside the cell. &nbsp;At the other end, Gupta coordinates with the product design team, typically mechanical engineers, who are creating the physical design of what the actual active material has to fit into. Gupta bridges the work of these two groups, drawing on the experiences he had as a student, taking their outputs and designing the battery management unit (BMU). The BMU in the Ray-Ban | Meta smart glasses is now the world’s smallest and has all the circuitry for protection, gauging, and charging.</p><p>Gupta’s interest in electronic materials was nurtured through his work with <a href="https://engineering.cmu.edu/directory/bios/whitacre-jay.html" target="_blank">Jay Whitacre</a>, professor of materials science and engineering, on batteries and energy technologies. When Gupta first enrolled as a student in the College of Engineering at Carnegie Mellon, he had no idea what materials science was. His initial interest was in electrical engineering, though he was also curious about nanotechnology. In his first year, he took the introduction to materials science and engineering course, and he was immediately drawn in. Later in his studies, Whitacre encouraged Gupta to think through bringing concepts to mass production, taking into account the economic influences and incremental changes in materials technologies.</p><p>“The idea of taking a concept and actually bringing it to mass production has stuck with me, both in my past role at Apple and now at Meta,” says Gupta, as he reflects on projects involving batteries for devices such as iPhones, Airpods, Apple Watches, and now the Quest 3 and Ray-Ban | Meta smart glasses.</p><p>While he did eventually go on to pursue a graduate degree in electrical engineering, he attributes his continued education to his background in materials science.</p><p>“The reason why I went back to electric engineering was because of my foundation in materials science, especially in batteries,” says Gupta. “I knew how batteries were made and how they worked, but I wanted to go beyond that.”</p><p>Gupta credits Carnegie Mellon’s emphasis on interdisciplinary studies focused on next generation problems to fostering his interest in batteries, as well as his approach to his work.</p><p>“Batteries in particular are extremely interdisciplinary. There’s the chemistry side with materials science, the mechanical side of physically making the cell, the electrical side of what to do with the energy that comes out of the cell, and the economic side of building a supply chain.”</p><blockquote><p>The idea of taking a concept and actually bringing it to mass production has stuck with me.</p><cite><strong>Ankur Gupta<cite id="isPasted">, MSE'10</cite></strong><br></cite></blockquote><p>Gupta draws on his materials science foundation still in his career today, recalling insights from Professor <a href="https://engineering.cmu.edu/directory/bios/heard-robert.html" target="_blank">Robert Heard</a>, who encouraged students to dive deep into a problem and think about it “at an atomic scale.”</p><p>“For battery packs, we have to really dive into the printed circuit board (PCB) materials. Even though it’s electrical engineering, it’s also materials science getting into what’s going on at the atomic level.”</p><p>Gupta draws on his own personal experiences of using the smart glasses to capture a photo, rather than trying to find his phone, to illustrate the ability that AR could have for users to experience the world, rather than looking down at phones. As Meta moves forward with developments for the Quest line of products with the goal of eventually functioning as a replacement to a traditional laptop, refining batteries to meet product design and functionality needs will be imperative.</p><p>“Some of the key steps involve being able to have a battery that can power all that a laptop can do, but in the size of a phone,” he says. “It takes a lot of engineering and innovation to compact all these features into a very small product.’</p><p>The pathway to a career in industry was not always clear, as the role of materials science in similar companies is not always immediately recognized, but Gupta encourages current students to think outside traditional career pathways.</p><p>“If you think that there’s a way for materials to impact a certain industry, there probably is,” he says. “Make connections, and you can find a way to show there is an avenue.”</p>

The <a href="https://ieeexplore.ieee.org/document/10269004" target="_blank">results</a> are reported in the journal <em>IEEE Transactions on Visualization and Computer Graphics</em>.</p><p>Virtual reality (VR) and related applications have been touted as game-changers for years, but outside of gaming, their promise has not fully materialised. “Users gain some qualities when using VR, but very few people want to use it for an extended period of time,” said <a href="https://pokristensson.com/" target="_blank">Professor Per Ola Kristensson</a> from Cambridge’s Department of Engineering, who led the research. “Beyond the visual fatigue and ergonomic issues, VR isn’t really offering anything you can’t get in the real world.”</p><p>Most users of desktop software will be familiar with the concept of hot keys – command shortcuts such as ctrl-c to copy and ctrl-v to paste. While these shortcuts omit the need to open a menu to find the right tool or command, they rely on the user having the correct command memorised.</p><p>“We wanted to take the concept of hot keys and turn it into something more meaningful for virtual reality – something that wouldn’t rely on the user having a shortcut in their head already,” said Kristensson, who is also co-Director of the <a href="https://www.chia.cam.ac.uk/" target="_blank">Centre for Human-Inspired Artificial Intelligence</a>.</p><p>Instead of hot keys, Kristensson and his colleagues developed ‘HotGestures’, where users perform a gesture with their hand to open and control the tool they need in 3D virtual reality environments.</p><p>For example, performing a cutting motion opens the scissor tool, and the spray motion opens the spray can tool. There is no need for the user to open a menu to find the tool they need, or to remember a specific shortcut. Users can seamlessly switch between different tools by performing different gestures during a task, without having to pause their work to browse a menu or to press a button on a controller or keyboard.</p><p>“We all communicate using our hands in the real world, so it made sense to extend this form of communication to the virtual world,” said Kristensson.</p><p>For the study, the researchers built a neural network gesture recognition system that can recognise gestures by performing predictions on an incoming hand joint data stream. The system was built to recognise ten different gestures associated with building 3D models: pen, cube, cylinder, sphere, palette, spray, cut, scale, duplicate and delete.</p><p>The team carried out two small studies where participants used HotGestures, menu commands or a combination. The gesture-based technique provided fast and effective shortcuts for tool selection and usage. Participants found HotGestures to be distinctive, fast, and easy to use while also complementing conventional menu-based interaction. The researchers designed the system so that there were no false activations – the gesture-based system was able to correctly recognise what was a command and what was normal hand movement. Overall, the gesture-based system was faster than a menu-based system.</p><p>“There is no VR system currently available that can do this,” said Kristensson. “If using VR is just like using a keyboard and a mouse, then what’s the point of using it? It needs to give you almost superhuman powers that you can’t get elsewhere.”</p><p>The researchers have made the source code and dataset publicly available so that designers of VR applications can incorporate it into their products.</p><p>“We want this to be a standard way of interacting with VR,” said Kristensson. “We’ve had the tired old metaphor of the filing cabinet for decades. We need new ways of interacting with technology, and we think this is a step in that direction. When done right, VR can be like magic.”</p><p>The research was supported in part by the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation (UKRI).</p><hr><p><em><strong>Reference:</strong><br>Zhaomou Song; John J Dudley; Per Ola Kristensson. ‘<a href="https://ieeexplore.ieee.org/document/10269004" target="_blank">HotGestures: Complementing Command Selection and Use with Delimiter-Free Gesture-Based Shortcuts in Virtual Reality</a>.’ IEEE Transactions on Visualization and Computer Graphics (2023).

Micera believes that exploring the cognitive limitations of third-arm control may actually provide gateways towards better understanding of the human brain.</p><p>Micera continues, “The main motivation of this third arm control is to understand the nervous system. If you challenge the brain to do something that is completely new, you can learn if the brain has the capacity to do it and if it’s possible to facilitate this learning. We can then transfer this knowledge to develop, for example, assistive devices for people with disabilities, or rehabilitation protocols after stroke.”</p><p>“We want to understand if our brains are hardwired to control what nature has given us, and we’ve shown that the human brain can adapt to coordinate new limbs in tandem with our biological ones,” explains Solaiman Shokur, co-PI of the study and EPFL Senior Scientist at the Neuro-X Institute. “It’s about acquiring new motor functions, enhancement beyond the existing functions of a given user, be it a healthy individual or a disabled one. From a nervous system perspective, it’s a continuum between rehabilitation and augmentation.”</p><p>To explore the cognitive constraints of augmentation, the researchers first built a virtual environment to test a healthy user’s capacity to control a virtual arm using movement of his or her diaphragm. They found that diaphragm control does not interfere with actions like controlling one’s physiological arms, one’s speech or gaze.</p><p>In this virtual reality setup, the user is equipped with a belt that measures diaphragm movement. Wearing a virtual reality headset, the user sees three arms: the right arm and hand, the left arm and hand, and a third arm between the two with a symmetric, six-fingered hand.</p><p>“We made this hand symmetric to avoid any bias towards either the left or the right hand,” explains Giulia Dominijanni, PhD student at EPFL’s Neuro-X Institute.</p><p>In the virtual environment, the user is then prompted to reach out with either the left hand, the right hand, or in the middle with the symmetric hand. In the real environment, the user holds onto an exoskeleton with both arms, which allows for control of the virtual left and right arms. Movement detected by the belt around the diaphragm is used for controlling the virtual middle, symmetric arm. The setup was tested on 61 healthy subjects in over 150 sessions.</p><p>“Diaphragm control of the third arm is actually very intuitive, with participants learning to control the extra limb very quickly,” explains Dominijanni. “Moreover, our control strategy is inherently independent from the biological limbs and we show that diaphragm control does not impact a user’s ability to speak coherently.”</p><p>The researchers also successfully tested diaphragm control with an actual robotic arm, a simplified one that consists of a rod that can be extended out, and back in. When the user contracts the diaphragm, the rod is extended out. In an experiment similar to the VR environment, the user is asked to reach and hover over target circles with her left or right hand, or with the robotic rod.</p><p>Besides the diaphragm, but not reported in the study, vestigial ear muscles have also been tested for feasibility in performing new tasks. In this approach, a user is equipped with ear sensors and trained to use fine ear muscle movement to control the displacement of a computer mouse.</p><p>“Users could potentially use these ear muscles to control an extra limb,” says Shokur, emphasizing that these alternative control strategies may help one day for the development of rehabilitation protocols for people with motor deficiencies.</p><p>Part of the third arm project, previous studies regarding the <a href="https://actu.epfl.ch/news/a-smart-artificial-hand-for-amputees-merges-user-a/" target="_blank">control of robotic arms</a> have been focused on helping amputees. The latest Science Robotics study is a step beyond repairing the human body towards augmentation.</p><p>“Our next step is to explore the use of more complex robotic devices using our various control strategies, to perform real-life tasks, both inside and outside of the laboratory. Only then will we be able to grasp the real potential of this approach,” concludes Micera.</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 302px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzAyNTY4NDIyNzU0LTgxOTJ4NTQ2NC5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 300px;" class="fr-fic fr-dib"><span class="fr-inner">Martina Gini controls a simplified robotic arm with breathing. © 2023 EPFL / Alain Herzog, CC-BY-SA</span></span></span></p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 302px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzAyNTY4NTQ4Mjg5LWV6Z2lmLTUtNDVjNDI4M2Y2Zi5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 300px;" class="fr-fic fr-dib"><span class="fr-inner">Silvestro Micera (left) and Leonardo Pollina (right) prepare for the third arm virtual reality experiment. © 2023 EPFL / Alain Herzog, CC-BY-SA</span></span></span></p>

Artificial Intelligence in Surgery: Augmented Reality provides Support in the Operating Room

<p dir="ltr" id="isPasted">As technology continues to advance, Wi-Fi has remained a key component in research and industrial manufacturing. With the introduction of Wi-Fi 7, organizations now have the opportunity to improve their value propositions and provide customers with an enhanced experience. This new wireless communication technology offers substantial benefits for those looking to stay ahead in the game.</p><h2 dir="ltr">The Journey to Wi-Fi 7</h2><p dir="ltr">Wi-Fi, which stands for wireless fidelity, was developed by an organization called the Institute of Electrical and Electronics Engineers (IEEE), who sets standards for the Wi-Fi standard. IEEE 802.11be, dubbed Extremely High Throughput (EHT), is the next amendment of the IEEE 802.11 standard, which will be designated Wi-Fi 7. IEEE 802.11be is still in the development stage, and it is expected that the specifications will be officially released in late 2024 or early 2025.&nbsp;</p><p dir="ltr">The IEEE 802.11be aims to define Media Access Control (MAC) and Physical Layer (PHY) features that are customized to meet the demanding requirements of high-throughput and low-latency applications. The PHY component of IEEE 802.11 is expected to be similar to the one outlined in IEEE 802.11ax standard. For instance, the IEEE 802.11be will incorporate support for technologies like multi-user multiple-input and multiple-output (MU-MIMO), orthogonal frequency division multiple access (OFDMA), and longer symbol durations with smaller subcarrier spacing.&nbsp;</p><h2 dir="ltr">Technical Specifications</h2><p dir="ltr">Recent reports indicate that Wi-Fi 7 has achieved a remarkable increase in wireless data link performance, nearly quadrupling the capabilities of its previous generation, offering a throughput exceeding 36 Gbps. To attain this impressive transfer rate, the IEEE 802.11be standard introduces a range of technological advancements, such as wider channels and higher quadrature amplitude modulation (QAM), that exhibit substantial improvements over its predecessor.&nbsp;</p><p dir="ltr">In Wi-Fi 6, the utilization of OFDMA involved breaking down radio channels into smaller frequency allocations known as Resource Units (RUs). This approach enabled Wi-Fi devices to send smaller data packets to multiple users concurrently, enhancing both throughput and reducing latency. Wi-Fi 7 builds upon this foundational OFDMA concept but introduces the notion of Multiple RUs (MRU), which allows for combinations of different RU sizes.</p><p dir="ltr">The enhancements introduced through MRU have led to a significant reduction in latency, especially when multiple users are attempting to transmit data simultaneously. This improvement is achieved by allocating RUs more efficiently, taking into account the varying data lengths of different users. For example, in a scenario where four users with different data lengths are transmitting data, a Wi-Fi 7 access point (AP) equipped with MRU can achieve the shortest end-to-end latency compared to previous-generation APs, resulting in a 33 percent reduction in latency compared to Wi-Fi 5 and a 25 percent reduction compared to Wi-Fi 6.&nbsp;<iframe id="652e6bda405966a620c0bedf" width="250" class="specs-iframe" height="440" src="https://wevolver.com/iframe/specs/nordic-semiconductor-nrf7002-dk-wi-fi-6-development-kit?iframe=true" frameborder="0" scrolling="false" data-lf-form-tracking-inspected-kn9eq4roawkarlvp="true" data-lf-yt-playback-inspected-kn9eq4roawkarlvp="true" data-lf-vimeo-playback-inspected-kn9eq4roawkarlvp="true"></iframe></p><h2 dir="ltr">How Does Wi-Fi 7 Achieve High Throughput?</h2><p dir="ltr">Wi-Fi 6 operated across two frequency bands—2.4 GHz and 5 GHz. In practical usage, only a portion of the available frequencies within each band were utilized, such as 80 MHz in the 2.4 GHz band and 600 MHz in the 5 GHz band. These specific sets of frequencies are referred to as the spectrum, and their actual size can <a href="https://www.lairdconnect.com/support/faqs/what-channels-are-supported-both-24-ghz-and-5ghz-band-most-countries" target="_blank">vary</a> between different countries.</p><h3 dir="ltr">Wider Channels</h3><p dir="ltr">While the previous generation of Wi-Fi could simultaneously handle 160 MHz channels, Wi-Fi 7 introduces a substantial improvement with ultra-wide 320 MHz channels. This advancement translates to a doubled data transmission capacity compared to the previous Wi-Fi 6 and 6E technologies. The broader channel not only minimizes latency but also enhances the overall transmission rate. These 320 MHz channels are situated in the relatively open 6 GHz band, steering clear of the frequently congested wireless transmission protocol bands. Consequently, this configuration reduces interference and ensures a more stable signal.</p><h3 dir="ltr">4K QAM for Higher Data Rate</h3><p dir="ltr">To leverage frequencies for faster computer speeds, Wi-Fi 6 uses a technique called quadrature amplitude modulation (QAM), supporting 1024 QAM. This means it can extract 1024 signals from these frequencies. The greater the number of signals, the more data bits it can carry, resulting in increased throughput. However, a choice must be made regarding the Wi-Fi channel within one of the frequency bands. For instance, in the 2.4 GHz band, a channel width of 20 MHz is typically used, and a broader channel width leads to higher throughput.</p><p dir="ltr">Comparing Wi-Fi 7 to its predecessors reveals significant advancements. Wi-Fi 7 boasts a data rate of 9.6 Gbps, a 39 percent increase compared to the previous generation, primarily due to the jump in QAM from 1024 QAM in Wi-Fi 6. Now, with the advent of Wi-Fi 7, even more enhancements have been introduced. The channel width has doubled, moving from 160 MHz to 320 MHz, effectively doubling the data rate. Additionally, the QAM has seen an improvement, increasing from 1024 QAM in Wi-Fi 6 to 4096 QAM, contributing an additional 20 percent to the data rate.</p><h3 dir="ltr">Improvements in MIMO</h3><p dir="ltr">Wi-Fi achieves data transmission between devices through specific Wi-Fi channels. To further enhance throughput, it utilizes a technique known as spatial streams, also referred to as MIMO. The Wi-Fi 7 standard expands the count of multi-user MIMO streams to 16. This increase in available MIMO streams, coupled with the capability to automatically select the most suitable stream for any given task, will result in a reduction in latency.&nbsp;</p><h3 dir="ltr">MLO for Wider Channels</h3><p dir="ltr">Wi-Fi 7 introduces enhancements to Multi-Link Operation (MLO). MLO enables the simultaneous utilization of multiple bands or channels by Multi-Link Devices. Embracing MLO provides advantages such as load balancing, data aggregation, and reduced latency. When employing the same modulation and coding scheme rate, Wi-Fi 7 with MLO delivers up to three times the effective throughput compared to Wi-Fi 6 with a single link. Furthermore, Wi-Fi 7 featuring MLO brings about an impressive 80 percent reduction in latency compared to the previous generation using a single link.</p><h2 dir="ltr">Why Use Wi-Fi 7 for Next-Gen Applications?</h2><h3 dir="ltr">Speed and Efficiency</h3><p dir="ltr">Wi-Fi 7 can leverage the capabilities of MLO to prioritize efficient data transmission, effectively managing network congestion and interference while optimizing the flow of data. With Wi-Fi 7 routers, dynamic channel selection becomes a key strategy to bypass congestion or interference, ensuring the smooth and reliable movement of data throughout the network.</p><h3 dir="ltr">Reliability</h3><p dir="ltr">In terms of reliability, Wi-Fi 7 elevates the&nbsp;dependability of wireless connections by maintaining a steady connection and mitigating interference, resulting in fewer disruptions and dropouts for users. This technology also addresses limitations associated with the coverage range of specific frequency bands. By intelligently selecting channels and optimizing transmission, it ensures that even in areas with limited signal coverage, connections remain resilient.</p><h3 dir="ltr">Adaptability</h3><p dir="ltr">One important feature of Wi-Fi 7 is its adaptability. By dynamically selecting the most appropriate channel according to current network conditions, it guarantees that the network can adapt to evolving environments and sustain peak performance. This adaptability inherent in Wi-Fi 7 not only ensures resilience but also future-proofs networks. As new devices and technologies come into play, Wi-Fi 7 can accommodate them by adeptly allocating resources and enhancing performance.</p><h2 dir="ltr">Potential Use Cases for Wi-Fi 7</h2><h3 dir="ltr">Real-Time Applications</h3><h4 dir="ltr">4K and 8K Streaming&nbsp;</h4><p dir="ltr">Recognizing Wi-Fi as the cornerstone of advancing digital technologies like edge computing and industrial automation, the introduction of Wi-Fi 7 marks a significant expansion of real-time applications, including the handling of 4K and 8K video streams.</p><h4 dir="ltr">AR and VR&nbsp;</h4><p dir="ltr">Wi-Fi 7 equips users to immerse themselves in technologies like augmented reality (AR) and virtual reality (VR) that offer experiences remarkably close to reality.

The article discusses the Wi-Fi 7– with improved speed, low latency, and better reliability for your wireless connections.


A short guide to the next generation of wireless connectivity-Wi-Fi 7

<p id="isPasted">For retailers, selling commodities, apparel, home appliances, etc., the amount of consumer information you collect greatly affects sales. Unless you accurately assess what customers want now and stock up on inventory during the optimal period when they are required, in the optimal quantities and at the lowest possible cost, you cannot grow your revenue. To succeed in the retail industry, it is an absolute requirement that you develop the ability to discern customer needs.</p><p>The retail industry has a long history of continuously developing technologies and business methods for handling customers and products, developing distribution strategies, and managing various other types of information. The industry has always adopted the latest up-to-date information processing technology. Here, we explain the movement called “retailtech,” which develops and uses the latest information technologies and has become widely used in the retail industry.</p><h2>Individually supporting diversifying consumer needs with digital technologies</h2><p>Retailtech is a term that combines “retail,” representing the retail industry, and “technology.” It means the incorporation of artificial intelligence (AI), IoT, and other leading-edge IT technologies into the collection and analysis of customer information, the management of distribution and inventory, settlement, etc. to increase their effectiveness and efficiency. Broadly speaking, robots that help with sales, robots that pick products to be delivered at distribution centers, and the shift to cashless settlement, etc. are also included in retailtech.</p><p>Since the start of the 21st century, the environment surrounding the retail industry has dramatically changed.</p><p>First, the sense of values, interests, and preferences of consumers have diversified due to market globalization and the filter bubble effect<sup>*1</sup> due to the expanded use of search engines, social networking services, and other Internet environments. As a result, it is becoming necessary to not only to grasp what is selling in the consumer market overall, but also to discern what items individual customers need and sell such items to them separately.</p><p>*1 The filter bubble effect refers to the phenomenon in which consumers are only able to see the information that they wish to see on the Internet. By continuing to collect and accumulate only information that matches their preferences without coming into contact with information that does not match their sense of values, individual consumers strengthen the tendency to develop radical preferences that are biased in a specific field only, and it is believed that diversification increases as a result.</p><p>Moreover, the information for retail shops to gain insight into customers is being digitized, and the location of commerce is shifting from real sales floors to Internet sites, which is a significant change. The digitization of customer information that started a long time ago from POS systems<sup>*2</sup> and the point cards issued by mass-market retailers is further evolving with the current spread of online shopping. Now, artificial intelligence (AI) analyzes user registration information, their search history on the Internet, and on-site behavior history to discern individual interests and preferences, what products they currently want, and the amount they might be able to pay to purchase a product. Furthermore, retail methods that propose products that individual consumers might want at the optimal time have become commonplace.</p><p>*2 A POS (Point of Sales) system scans the barcode attached to a product when sales are made at the cash register on the sales floor to manage what products were sold when and where. It is used to collect information for effectively managing products, inventory, and customers.</p><p>The use of digital technologies is essential to individually responding to diversified consumer needs. If you are a skilled marketer, changes in market trends can be picked up from market information using your experience and sense. However, a person cannot make decisions about the individual needs and desired products for a massive number of consumers. Therefore, the use of AI and other forms of IT to replace the skills of a marketer and respond to individual consumers as needed becomes essential.</p><h2>Integrating brick-and-mortar stores and online stores in order not to miss a targeted customer</h2><p>In recent years, the movement to integrate online sales and product sales at brick-and-mortar stores by using the latest technologies is becoming apparent in the retail industry. This sales method, which collects customer information through multiple channels and aims to build a mechanism that can sell according to the method desired by each customer, is called “OMO” (Online Merges with Offline) (Figure 1).</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 768px;"><span class="fr-img-wrap"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1699267693485-various-tech-8-2en.png" style="width: 766px;" class="fr-fic fr-dib"><span class="fr-inner">Figure 1 Utilize IoT to integrate customer information from brick-and-mortar and online stores</span></span></span></p><p id="isPasted">Since the start of the 21st century, measures have rapidly developed to increase sales at online stores. However, brick-and-mortar stores and online stores each have their advantages and disadvantages. To increase the degree of satisfaction without missing a customer, it is more rational to separately use the characteristics of both types of stores according to customers’ needs. Therefore, the number of retail companies that are advancing attempts to utilize IoT to make it possible to collect the kind of detailed customer information that is collected online at brick-and-mortar stores is increasing in recent years.</p><p>Two technologies that are being utilized in various applications as a means to follow the movements of store customers and products within a brick-and-mortar store and collect customer information are image recognition and RFID<sup>*3</sup> tags (Figure 2).</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 768px;"><span class="fr-img-wrap"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1699267714710-various-tech-8-3.jpg" style="width: 766px;" class="fr-fic fr-dib"><span class="fr-inner">Figure 2 Collecting customer information with RFID, etc. and providing a high-quality customer experience with AR, etc. A product with an RFID tag attached (left) and utilizing AR to consider a furniture purchase (right)</span></span></span></p><p id="isPasted">*3 RFID (Radio Frequency Identification) is a technology that uses radio waves to read and write data without contact. By attaching a small semiconductor chip that stores an RFID mechanism and information as a tag to each individual product, it becomes possible to carry out fine-grained management of products by reading and writing information with RFID as needed.</p><p>Retail shops that have installed a large number of cameras, various sensors, microphones, and RFIDs, etc. and introduced IoT systems with AI that analyzes in real time what store customers picked up. The customer information that was collected with previous POS systems and point cards could not be collected unless a customer actually purchased a product. By utilizing such IoT systems, it becomes possible to know what products a store customer was comparing and what they ultimately bought.</p><p>If you utilize information collected in this way, you can take various measures such as sending special deal information to customer smartphone apps to give them a push, providing a reminder several days later about a product that they were interested in but did not purchase, optimizing the types, placement location, and flow lines of products displayed in the store in order not to miss customers. Moreover, if you install sensors on the product shelves and attach RFID tags to the products, you will become able to assess the product display conditions in real time to enable efficient sales that never miss a business opportunity through highly precise inventory management and just-in-time product replenishment.</p><p>In addition, it also became possible to identify the products to purchase and smoothly complete the checkout process just by placing the shopping basket in the designated location at the self-checkout terminal and scanning the RFID tags attached to the products. For store customers who created an account in advance at a cutting-edge store, it is even possible to automatically check out when carrying goods out of the store even if you do not pay at the register. With such mechanisms, the stress of waiting for the register will be eliminated.</p><h2>Providing a high-quality customer experience utilizing AR and VR</h2><p>Some retail stores are introducing systems that utilize augmented reality (AR) technology to provide assistance in selecting a product to purchase or to make accurate suggestions about how to use a product or what product to purchase on that occasion.</p><p>For example, there is a mass furniture retailer that provides an AR app that enables users to check on a smartphone or tablet device display what a piece of furniture they are thinking about purchasing would look like when actually placed in their own room. The impression given off by a piece of furniture changes considerably from the showroom to the location where it is actually placed. Depending on the situation, it may be too large to get into the room. By utilizing an AR app, you can avoid making the wrong choice and shop with a high degree of satisfaction. In the future, it might become possible to utilize virtual reality (VR) with haptic technology, etc. to check how a sofa feels, etc. online.</p><p>There are also supermarkets providing AR apps that can display the basic ingredients, place of production, allergens, etc. of products lined up in the food section. Recently, there are also stores creating systems that present cooking recipes using those ingredients or the seasonings needed to make a dish so that you can purchase them together.</p><p>In the retail industry, entertainment that moves people is required by sensitively perceiving the customer’s emotions and preparing the expected services in advance. All consumers want to enjoy their shopping. Going forward, more advanced forms of retailtech will appear one after another and likely provide new forms of enjoyment to consumers.</p><hr id="isPasted"><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1699267752774-1699267752774.png" class="fr-fic fr-dii"></p><p>If you have any questions based on this article that you would like to discuss with an expert at Murata, don't hesitate to reach out.

Podcast: Key To Unlock Immersive Holograms

<p><span style="background-color: transparent;">Virtual Reality (VR) has transformed how we interact with digital content by providing immersive and captivating experiences within virtual environments. However, behind the awe-inspiring experiences, there is a complex engineering set, which includes high-resolution displays, accurate tracking, powerful rendering techniques and GPUs, efficient data and heat transfer technologies, miniaturization, and more.&nbsp;</span></p><p>This article steps into the fascinating but challenging world of VR hardware engineering. It explores technologies that have been used to create high-efficient, lightweight, and miniaturized headsets.</p><h2>Optics and Display Systems</h2><p>VR headsets use high-resolution displays and optics to create immersive visual experiences. These devices are designed to transport users into virtual worlds by presenting stereoscopic images that mimic real-life depth perception.</p><p>In the context of miniaturizing VR hardware, optimizing optics and display systems becomes crucial. Maintaining high-resolution displays while reducing the size, weight, and power consumption of the headset is complex. This requires advancements in display technologies, such as miniaturized OLED or LCD panels with high pixel density. Nanotechnology plays a crucial role in advancing display technology for VR applications, particularly in achieving higher resolutions. It enables the fabrication of smaller pixels, resulting in higher pixel density and enhanced image sharpness. In addition, the demanding data transfer protocols necessary for VR, such as 5G, heavily rely on advancements in nanotechnology.</p><p>To address size constraints, engineers have focused on compacting the optical systems while maintaining wide fields of view. Advanced lens design techniques, such as aspherical lenses, can help achieve a wider FOV while minimizing the physical size of the optics. Additionally, distortion correction algorithms play a significant role in compensating for geometric distortions and ensuring image quality across the entire display area.</p><p>Reducing motion blur is another challenge in VR hardware. Increasing the display&#39;s refresh rate and optimizing response times of the display technology help minimize motion blur during head movements. Advanced motion smoothing techniques, such as motion vector prediction and frame interpolation, can further enhance the visual experience.</p><p>To address the screen door effect in a miniaturized VR headset, display technologies with higher pixel density and improved sub-pixel arrangement should be considered. Additionally, incorporating optical filters like diffusers or anti-reflective coatings can help reduce the visibility of pixel gaps and enhance the overall visual quality.</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 302px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNjg5NzYyOTM3NDU1LU1vdGlvbiBibHVyLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 300px;" class="fr-fic fr-dib"><span class="fr-inner" spellcheck="false">Motion blur caused by full persistence display. Image credit: Oculus.</span></span></span></p><h2>Tracking and Positional Accuracy</h2><p>Another important piece of the VR hardware set is the tracking system. However, capturing user movements accurately while minimizing the size and power requirements of the tracking components has been a big challenge.</p><p>Traditional tracking systems employ active IR and laser-based systems for tracking. Active IR tracking involves emitting infrared light from a source and using sensors to detect reflections from markers on the user&#39;s head or peripherals. On the other hand, laser-based tracking systems use lasers and sensors to measure the time the rays return after hitting markers, allowing for accurate motion tracking. However, adapting these systems for miniaturized hardware requires advancements in sensor miniaturization and energy-efficient designs.</p><p>Also, integrating sensors and combining data from multiple sensors is crucial in improving accuracy and reducing latency. By integrating sensor functionality into a compact form factor, the overall footprint of the tracking system can be minimized. Additionally, leveraging prediction and filtering algorithms helps smooth out movements and ensures real-time responsiveness.</p><p>Occlusion is another challenge in tracking systems when objects obstruct the line of sight between sensors and markers, leading to inaccurate or lost tracking. In order to minimize these problems, techniques like sensor integration, inverse kinematics, and sensor fusion can be employed.</p><p>Achieving precise positional accuracy in VR can be challenging due to sensor limitations, calibration requirements, environmental factors, and system latency. Calibration techniques can align sensors and markers for accuracy, and sensor resolution and precision provide detailed and precise tracking. Furthermore, sensor fusion can also optimize positional tracking by combining data from multiple sensors.</p><h2><strong>Graphics Processing Units (GPUs) and Rendering Techniques</strong></h2><p>VR systems have been taken to a higher level due to the advance of GPU technology. Some of these improvements are higher frame rates and lower latency, which can be achieved by dividing complex tasks into smaller subtasks and executing them simultaneously across multiple parallel processing units. The performance of GPUs can be further improved through optimization techniques, such as fine-tuning algorithms and system configurations, to maximize efficiency and reduce processing overhead.</p><p>Asynchronous Time Warp (ATW) and Space Warp (ASW) are techniques that have been used to ensure a smooth, immersive VR experience. ATW predicts head movements and warps previously rendered frames accordingly, reducing visual lag. ASW extrapolates intermediate frames based on head and hand motion, reducing latency and improving system responsiveness.</p><p>VR is also enhanced by real-time rendering algorithms that create immersive visuals. These algorithms utilize techniques such as Level of Detail (LOD) management, which adjusts the level of detail in objects based on their distance from the viewer for efficient use of computational resources. Culling and occlusion techniques are also used to eliminate the need to render objects that are not visible, which reduces unnecessary computations. Furthermore, dynamic lighting and shading techniques simulate realistic lighting conditions, creating more visually natural virtual environments.</p><h3>Connectivity and Data Transfer</h3><p>During transmitting data without physical connections, VR systems rely on wireless communication protocols like Bluetooth and Wi-Fi. For a seamless experience, low latency and high bandwidth are crucial. Furthermore, interference mitigation and Quality of Service (QoS) techniques help maintain a robust wireless communication link by prioritizing essential data and minimizing the impact of external signals.</p><p>Good signal range and stable connections are necessary to prevent disruptions or dropouts during usage. Therefore, the signal range determines the maximum distance between the transmitter and receiver, while stability refers to the reliability of the connection.</p><p>Nanotechnology plays a pivotal role in establishing seamless and responsive communication between various elements of virtual reality by bridging the gaps that exist between processors and input environments. Moreover, in order to minimize the amount of data transmitted over wireless channels, data compression techniques can be used. Lossless compression preserves all original data, while lossy compression sacrifices some details to achieve higher compression ratios. Still, adaptive compression adjusts the compression level based on the available bandwidth and quality requirements.</p><p>Minimizing delays during data compression and decompression processes to maintain real-time interactions in VR is also complex. In order to mitigate this issue, synchronization methods like time stamping enable precise timing coordination between devices and buffering and interpolation techniques smooth out variations in data transmission rates.</p><h3>Power Management and Heat Dissipation</h3><p>In order to ensure maximum battery life and reduce power stress, VR headsets rely on power efficiency techniques, which can be enhanced by leveraging nanotechnology. This involves carefully selecting energy-efficient components and implementing power optimization methods like voltage scaling, clock gating, and dynamic power management. Nanoscale materials and structures can improve power efficiency by enabling better control over power consumption and minimizing energy loss.</p><p>Moreover, thermal management is crucial during the operation of VR headsets, as they generate substantial heat. Nanotechnology can play a role in thermal management by offering advanced materials and designs that facilitate efficient heat distribution and dissipation.
