Towards a Transparent Proactive User Interface for a Shopping Assistant

In this paper we describe an adaptive shopping assistant system that utilises plan recognition. Radio Frequency Identification (RFID) sensory is used to transparently observe a shopper's actions, from which the plan recogniser tries to infer the goals of the user. Using this information, a proactive mobile assistant mounted on an instrumented shopping cart offers adapted support tailored to the shopper's concrete needs.
