| Outline of Final Research Achievements |
In this research project, we proposed an assistive system to help visually impaired individuals (users) not only detect obstacles in their vicinity, but also recognize what these objects are. The following three items were conducted: (1) we built recognition methods of several objects, such as chairs, desks, stairs, elevators, and handrails, by use of RGB-D sensors, such as Microsoft Kinect. (2) We also developed user interface systems based on vibrators, loudspeakers, microphones, and voice recognition technique. The user interface system allowed users to instruct the system and to understand the output of the system easily. (3) We conducted user studies to evaluate our assistive system. We compare our system with a conventional white cane, and confirmed that our system was more effective to find target objects.
