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.

Conditions

Interventions

DEVICE

initial system

The computer vision system is used to assist blind subject to navigate an extended path with multiple turns within a hospital setting.The initial prototype system would have been successfully tested for outdoor navigation and basic object recognition tasks.

DEVICE

modified system

The problems associated with the initial system were identified and modified. This modified system was tested with a second separate group of subjects. The redesigned system is used to assist blind subject to navigate the same extended path with multiple turns within a hospital setting.
