IBM's Stephen Boden shows off a personal tracking device built around RFID and Ultrawideband technology. Codeveloped by partner Ubisense, which describes itself as a smart-space company, the device allows multiple individuals to be tracked around a room or complex.
The tag also supports two-way communication using a standard radio channel. Buttons on the tag can be used to send information or unlock doors, and the tag's programmable LED and buzzer could be used to remind a patient to take medication.
