Abstract

An information processing apparatus includes a table with an embedded display device that has a surface on which an object with a wireless tag can be placed. An antenna unit is configured to move along a predetermined path and to transmit an interrogation wave for reading information from wireless tags. The antenna unit receives a response wave from wireless tags at different positions on the predetermined path. A controller is configured to: calculate changes in phase difference between the interrogation wave and the response wave received at the different positions; determine a location of a wireless tag on the surface of the embedded display device using the calculated changes in the phase difference; and then control the embedded display device to indicate the determined location.
