Abstract
Detecting information relating to a medium in an interactive media device. The device includes a surface able to receive the medium and a sensor network embedded within the surface. The sensor network includes a configuration able to detect medium information. The device has a processor able to issue signals to the sensor network and to receive signals indicating capacitance change caused by proximity of a region of the medium to the sensor network. Thus, the processor is able to detect medium information based on the capacitance change.
