Indoor Information Support System Using Optical Wireless Communications Technique

摘要

Optical wireless communications system with a corner-reflecting terminal and a distance image camera is proposed for location-based information support. By using the corner-reflecting terminal and the distance image camera, the user location can be tracked and detected, and the distance from the camera to the user who is tracked can be obtained real-timely. Therefore, the information support of users can be implemented based only on their physical locations and without the private data such as an address or ID number. We also performed several experiments based on the proposed system and method, and their effectiveness is demonstrated in multi-terminal location detection and indoor data communications.
