iPoint: a passively-powered information tag readable by commodity smartphones

Lead Presenter: Hooman Javaheri

We introduce iPoint, a communication system including a passively-powered wireless receiver capable of establishing two-way communication with a commodity smartphone. In contrast to traditional RFID tags, iPoint provides high computation and sensing capabilities and most importantly does not require specialized reader device to communicate. We prototype and experimentally evaluate our design that includes optimization techniques to ensure efficient delivery of energy and information and novel communication protocols.
