Computer Vision System for the Blind Veteran

Status Completed

Clinical Trial Summary

This is a feasibility study involving a small number of blind subject to evaluate the effectiveness of using a software and associated hardware components to assist the blind in identifying and locating objects of interests and to assist in way finding tasks. After the system has been successfully tested by the blindfolded engineers, it will be evaluated in a small number of blind subjects.

Clinical Trial Description

This is primarily an engineering project to develop computer vision algorithms for an integrated system comprising of a laptop computer, webcam, gps, digital compass, microphone, and stereo earphones. The system will be voice controlled. The algorithm will be trained to identify and located objects and navigationally landmarks in real-time, previously selected by sighted developers. After the system has passed objective engineering milestones, blind subjects will be tested to determine whether the novel system will improve the ability of the blind to travel over a test course in a hospital setting. ;
