<sod>This project, presented in 2015,<ref>{{cite journal|last=Ambard|first=Maxime|author2=Benezeth Y. |author3=Pfister P. |title=Mobile video-to-audio transducer and motion detection for sensory substitution|journal=Frontiers in ICT, Virtual environments|date=2015|doi=10.3389/fict.2015.00020|url=http://journal.frontiersin.org/article/10.3389/fict.2015.00020/full}}</ref> proposes a new versatile mobile device and a sonification method specifically designed to the pedestrian locomotion of the visually impaired. It sonifies in real-time spatial information from a video stream acquired at a standard frame rate. The device is composed of a miniature camera integrated into a glasses frame which is connected to a battery-powered minicomputer worn around the neck with a strap. The audio signal is transmitted to the user via headphones for running. This system has two operating modes. With the first mode, when the user is static, only the edges of the moving objects are sonified. With the second mode, when the user is moving, the edges of both static and moving objects are sonified. Thus, the video stream is simplified by extracting only the edges of objects that can become dangerous obstacles. The system enables the localization of moving objects, the estimation of trajectories, and the detection of approaching objects.<eod>
