visuPlus Active App

To support people with visual impairment, we developed a mobile visual aid with Ollendorf measuring systems. The app for Android tablets and phablets has an implementation based on OpenGL which allows a fast and smooth filtering of live video streams with contrasting colors. The integration of Abby OCR enables text recognition and transcription into digital text.

My job was the main lead and management of the project, the technical monitoring of the development of the Android app as well as the direct contact with the client.
