Abstract:
A robot 150 is placed on a touch panel. When touch sensor action sections 156a to 156c provided on a bottom face 150b of the robot act on a touch pad, an information processing device shows a face image in a rectangular area 16 of a display screen 14 of the touch panel. The rectangular area 16 corresponds to the bottom face of the robot. The face image is grabbed from the bottom face 150b of the robot 150 and appears in a face section 152. Further, the brightness of pixels in areas 18a and 18b of the display screen 14 is changed. The areas 18a and 18b correspond to optical sensors 160a and 160b provided on the bottom face 150b of the robot. The robot 150 detects the change in question, converting the change into a motion of an internal actuator, sound output, light emission, and so on in accordance with predetermined rules.
