Abstract
A system for evaluating human interactions with items, such as products displayed on shelves, includes at least one wireless reader which collects data from a set of associated wireless tags in an interrogation zone. The tags and readers may be based on RFID technology. The collected data includes an identifier for an item that is associated with each wireless tag and a touch sensor status indicating whether the item is being touched. A computer receives and aggregates the collected data and outputs an evaluation of human interactions with the items based on the data.
