Popis:	People with visual impairment have problems detecting obstacles when walking. New technologies have been used to improve their mobility. This paper presents an obstacle detection system that is compact, flexible and wearable. It utilizes ultrasonic sensors to detect obstacles and provide auditory feedback. The system is composed of two separate parts that communicate wirelessly. One part can be conveniently fitted on the users' footwear, and the other part on the ear, for audio cue. It is calibrated such that the user gets an idea of the distance from obstacles. Usability test results show that users can navigate around obstacles with minimal training.
