The joint research and development work between the University of Applied Sciences under the direction of Professor Dr Jörn Justiz, the university and the project initiator André Reber was made possible by Innosuisse, the Swiss Innovation Promotion Agency (then still CTI), as part of an 18-month project. This collaboration resulted in the first functional prototype. The project was also supported by the Economic Development Agency of the Canton of Bern.
The visual aid's output optics proved to be one of the most important and complex parts of the development. It turned out that the simplest solution was to combine a small screen with specially adapted optics. This allows the display to be held close to the eye and generate an enormously large virtual image. Thanks to the special eyecup, the influence of extraneous light can be reduced to an absolute minimum. A very small auto-focus camera serves as the image capture system. A modern mobile processor controls the device and provides enough power to capture, filter and magnify the images. All components are integrated into a compact and ergonomic housing that can be easily carried around in everyday life.
