Abstract
The purpose of this study is to support an independent life of person with the acquired visual impairment. In this study, an attempt is made to develop a walking support system comfortable for acquired visually impaired users. Support systems for a person who has the congenital visual impairment have been developed by various researchers. In existing researches, walking support systems have been used by combining with the Braille and the white cane. However, the acquired impaired feels stress against the use of these systems. This is because the life with the visual impairment is extremely-different from the past custom. In addition, the treatment as the visually impaired injures that person's pride. Therefore, it is necessary to develop a support system that considers a person with the acquired visual impairment. In the proposed system, an attempt is made to support a walking with a small wearable camera in consideration of the comfort of user. In this paper, several experiments are presented to demonstrate that the proposed system can detect a person who has possibilities to collide with a user.
