objSampler: A Tool for Recording and Recalling Encounters with Real World Objects

This paper proposes a tool, called objSampler, for recording and recalling encounters with real world objects, such as products, places, and individuals. It consists of a state-of-art device called objPipette to record conscious encounters, uCore for recording unconscious encounters, and objScope associated with objDish for recalling encounters on GUI. We adopted RFID technology to record conscious encounters and RF beacons for unconscious encounter recording. Since objSampler does not require a public backbone network between these devices, the recorded information is kept in private without security problems. We also proposes a filtered recording that is configurable with area coverage and detention time, and a filtered recalling that shows recorded encounters with prioritized order. These contribute to reduce noise in the recorded encounters.
