Audio-tactile Mobile Vision System for the Blind

The aim of our project is to build an audio-tactile mobile vision system to help blind people recognize the surrounding environment and understand it. The user gets data from the system by touching the screen of the smartphone then appropriate tones display informative data about the place being touched on the image which the system collected by an external camera.

Our main challenge is to give the user the data he really needs by extracting features of the scene's image in real time and pass this information in a simple, clear way to the user by sound where he can understand this information according to the surrounding environment. Another challenge is to make the system as easy as possible to learn.
