INTERACTIVE LOCALIZATION AND RECOGNITION OF OBJECTS FOR THE BLIND

The foundation of any orientation and navigation system for the blind is an accurate determination of the user’s position and the location of objects within his environment. This is also the reason why most available systems have weaknesses or even fail. In order to address this problem, we previously focused on indoor environments. One reason for this approach is that localization within indoor environments is more difficult, since GPS signals are normally unavailable. The second reason is that, if we can solve the localization problem indoors, it should also be possible to solve it outdoors by combining our assistant with the global positioning system.
