简要总结
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.
详细描述
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.

结局指标
主要结局
Frequency of Device Failures Per Attempt to Complete a Navigation Course
时间窗: The subject is given as much time as needed to complete the task
device failures were defined as any failure to provide correct location and direction information at thre appropriate time, resulting in a mistake that needed the initial prototype's ability to meet their travel needs at a good to excellent range.
次要结局
- Ability to Meet the Subjective Travel Needs of the Blind Subject(no time limit)
