ETH graduates reinvent the user manual

No sooner had David Shapira and Kordian Caplazi finished their studies than they set about creating a start-​up. Rimon develops virtual user manuals for industrial companies, enabling users to quickly and intuitively learn how to operate complex machines with the aid of AR glasses.

David Shapira and Kordian Caplazi have three things in common: they are young, have an ETH degree in their pockets and knew before they graduated that they wanted to become self-employed. With the founding of Rimon Technologies in August 2020, they have fulfilled their dream of starting their own company The start-up is so successful that four more members joined the team last year.

Rimon develops virtual user manuals for industrial companies to support technicians and frontline workers frontline workers when commissioning new equipment or repairing it. Instead of working their way through a tedious paper-based handbook, users wear augmented reality glasses that guide them step by step through complex instructions, providing them with the information they need exactly when and where they need it.

Augmented reality should not be confused with virtual reality, which involves becoming completely immersed in a virtual world. AR glasses, in contrast, provide a clear view of the real environment and overlay it with digital elements. In the case of augmented user manuals, the glasses project explanatory videos, interactive text fields or even 3D machine models into the field of view.

Out of the lab and into the field

“Our customers often only understand exactly what we do when we put AR glasses on them,” says Shapira, laughing. The “Coffee Case”, a step-by-step guide to preparing coffee with a barista machine, is a fitting choice for a demonstration. The 29-year-old originally developed this user manual as a semester project back in early 2019.

Shapira first became acquainted with AR technology and its possible applications in an elective lecture during his mechanical engineering studies. “I was fascinated by how AR glasses could present information in a different way,” he says. Caplazi, who also attended the lecture, adds: “Because it’s a young technology, there was a lot of space for new ideas.” It soon became clear to both of them that they wanted to take a closer look at AR in their Master’s theses.

Shapira came to his project through a happy coincidence, having got into conversation with the technical director of the locking systems company Dormakaba, who was visiting the mechanical engineering laboratories at ETH. The Master student talked about the possible AR applications he saw for the industrial company. Dormakaba was convinced, and Shapira set about demonstrating in a practical study the potential of the new technology in Dormakaba’s operations.

Emergency Covid solution proves successful

For his study, Shapira designed a virtual instruction manual that guides users through the assembly of a security door system for commercial buildings. “The door system was a good case study because it was being installed only rarely at the time,” he explains. Training service technicians to do this work is correspondingly time-consuming. The plan was to compare the difference in the technicians’ performance following conventional training and instruction via AR glasses.

But as with so much other practical work, Covid threw a spanner in the works here too, and Shapira was unable to perform the planned study with industry employees during lockdown. The emergency solution was to use mechanical engineering students. With no prior knowledge of the security door system or how to use the 3D glasses, all of the students completed the assembly process with no mistakes. “I never expected that,” says Shapira.

At the same time, his fellow student Caplazi was focusing his Master’s thesis on the way in which hand and eye movements can be used to predict subsequent actions of AR users. This would make it possible to warn them of dangerous situations in good time. Shapira and Caplazi exchanged ideas and experiences and continued to experiment industriously in their free time, both becoming increasingly convinced that AR instructions were an area with a great deal of potential. In August 2020, their start-up was founded.

A diverse customer base

Today, a team of six works on further developing the AR user manuals – two team members focus exclusively on programming, while a designer takes care of the visual aspects. The aim is to design a program interface that guides users through the process as intuitively as possible. “Unlike social media apps, there aren’t any best-practice examples for AR instructions as yet,” says Caplazi.

The start-up’s customer base is diverse, incorporating companies from heating technology, energy technology and even kitchen companies, from international corporations to small SMEs. Rimon works closely with industry representatives on a project basis to find the appropriate application for each company. “We’ve seen in practice that companies often have similar needs,” says Roder.

 "We have enough scientific knowledge. Now it’s a matter of finding useful applications.” - Lukas Roder, young entrepreneur   

The food technology graduate, who brings experience from a previous start-up, is active primarily in sales. Like probably many others, he first considered going on to complete a doctorate after graduating, says the 28-year-old. In the field of augmented reality, however, it quickly became clear to Roder that: “We have enough scientific knowledge. Now it’s a matter of finding useful applications.”

AR instructions bring particular added value to contracts from abroad and training, both made more difficult by the pandemic. If a machine breaks down at a customer’s premises abroad, the company can send AR glasses instead of a technician, thereby not only offering a faster service but also cutting costs. Training can now be provided regardless of location, or for one employee at a time.

Rapid developments in technology

The start-up is currently working on a project with a heating technology company, in which the use of AR glasses as a training tool offers even greater potential. The switch to renewable energies and heating systems means that the company will have to retrain large parts of its workforce in a short time. “Seventy percent of the service technicians have been trained to work with fossil-fuel heating systems,” explains Caplazi. AR instructions help the company keep pace with technological change.

Rimon faces tough competition – tech giants such as Microsoft are also working on AR instructions for various uses. “Right now, the whole industry is trying to find out which AR applications work,” says Roder. As a result, the ETH start-up is currently concentrating on solutions for the mechanical engineering industry, where the two company founders already have plenty of expertise. Next, the young entrepreneurs plan to launch a self-service platform that will enable companies to create AR instructions themselves.
