Abstract

A video-based spatial optical communication method for a wearable information terminal using a video camera with an infrared LED ring is proposed. By the video image of the wearable terminal that is captured by the camera, the physical location of the terminal and user's messages that are carried by it can be detected simultaneously. Therefore, data communication can be implemented without the private data of users such as an address or ID number; thus the security and privacy of users will be maintained. The effectiveness of this method is demonstrated in a multilanguage communication terminal for a wearable information environment.
