Individual-tracking information display system

Radio-frequency identification (RFID) is an automated identification process based on the storage and retrieval of data using transponders or RFID tags. These tags are often associated with objects that may be quickly inventoried, such as product palettes, library materials, or passports.

Keio University researchers have re-envisioned the use of RFID tags with people to develop a new information display system. The resulting Paravision is a dynamic sign system that projects information on a transparent screen. Designed for public spaces, Paravision tracks RFID devices carried by individuals and associates their personal information, stored on a computer or in a network, with their current spatial positions and projects this information onto the transparent screen. Possible applications include interactive exhibitions, automated concierge services, advertising, gaming, and surveillance.
