Abstract: This paper presents a guidance system for assisting the visually impaired people in structured indoor and partially outdoor environments. The system consists of a number of encoded infrared sheet of light beacons installed at appropriate locations and a small receiver module attached to the shoulder of the visually impaired person. The system is intended for use in indoor environments, such as home, office buildings, supermarkets and airports. The Digital Infrared Sheet of Light Beacons (DISLiB) transmit the encoded location information, while an infrared receiver module decodes this data and the appropriate message is retrieved from the corresponding memory in a voice recorder/playback chip. The orientation of the person can also be informed through natural language for better assistance.
