ReachBand is a wireless wristband with an RFID reader that can detect user interactions with everyday objects, such as holding a book or opening a door. ReachBand enables the delivery of personalized services and just-in-time information to the user. It is used by various projects at the Lab, such as ReachMedia and Ambient Semantics. ReachBand v2 is being further developed, and will include updated electronics and communcation capabilities, as well as reduced dependence on a PC.
