The MouseField, by Koji Tsukada, Toshiyuki Masui and Itiro Siio, combines an RFID reader and motion sensors to detect an object and movements after the object is placed on it. The system can interpret the user’s action as a command to control the flow of information, without using special controllers.

For example, you can listen to music with just a MouseField and RFID’d CD jackets. All the music in the CD has been previously saved in a music server. When you place a jacket on the MouseField, a music player appears on the screen, shows the contents of the CD, and starts playing the music. You can change the sound volume by rotating the CD jacket, and move to the next or previous track by sliding the jacket to the front or to the back. To stop the music, just remove the jacket from the MouseField
