A system for users to play games on regular surface ( 201 ) such as printed material is provided. The system consists of an ultrasonic pointing unit ( 216 ), an ultrasonic base unit ( 213 ), a control unit ( 220 ) and a response unit ( 240 ), together with response data ( 500 ) and game rules ( 1100 ). The user interacts with the surface ( 201 ) by placing the ultrasonic pointing unit ( 216 ) on various areas of the surface ( 10 ). Ultrasonic wave propagates between the ultrasonic point unit ( 216 ) and ultrasonic base unit ( 213 ). By measuring multiple time-of-flight of ultrasonic wave, the location of the ultrasonic pointing unit ( 216 ) could be determined, and the device makes appropriate audio or other responses. Also, with the additions of game rules ( 1100 ), the system could ask users questions, or instruct users to tracing pictures or letters, or instruct users to walk a maze, etc. A surface ( 201 ) is thereby transformed into an interactive experience with various sound or visual effects. The sound effects or other response data ( 540 ) and game rules ( 1100 ) are stored in data storage ( 230 ) accessible by the control unit ( 220 ). Any number of different surfaces ( 201 ) can be used as long as the specific response data ( 540 ) for each different surface ( 201 ) is stored in data storage ( 230 ) accessible by the control unit ( 220 ).
