A new simple and versatile input device called the MouseField, which enables users to control various information appliances easily without huge amount of cost. A MouseField consists of an ID recognizer and motion sensors that can detect an object and its movement after the object is placed on it. The system can interpret the user’s action as a command to control the flow of information.

Implementation of MouseField which consists of two motion sensors (taken from standard optical mouses) and an RFID reader (Texas Instruments S2000 Micro Reader) hidden under the surface. The RFID reader and the two optical mouses are connected to a PC through a USB cable, and they can detect the ID and the motion of the object put on the device. When a user puts an object with an RFID on the MouseField, it first detects what was put on the RFID reader. When the user moves or rotates the object, motion sensors detects the direction and rotation of the object.

An example of the interface where a user can enjoy music using a MouseField and CD cases which represent the music in the CD. All the music in the CD are saved in a music server, and an RFID tag is attached to each CD case. When a user places a CD case on the MouseField, a music player is displayed on the screen, shows the contents of the CD, and starts playing the music. The user can change the sound volume by rotating the CD case, and move to the next or previous music by sliding the case to the front or to the back. When the user removes the case from the MouseField, the sound stops and a screen saver is displayed placing a CD case starts playing music sliding the CD case plays the next music rotating the CD case changes the sound volume on the screen.

This is an experimental project, but the idea is very interesting.

DIFRWEAR’s stylish RFID blocking wallets and passport cases are made of the finest quality leather and are built to last. They contain a layer of RF shielding that prevents RFID readers from reading any passive tags stored within. They have a convenient flap to allow easy “flip” access to RFID cards. To allow RFID devices to be read, simply open the wallet or the passport case and direct it towards the reader.


The RFID tags in identification cards have been shown to be insecure. Attackers are able to read and copy information stored on these tags to create copies they can use themselves! But with these wallets and passport cases you’ll have the ability to control when, how and by whom your cards are accessed.

The price of the RFID Blocking Wallet is $15 for the black and $16 for the pink and red models, the price of the passport case is $18 for the black and $19 for the red an tan models.
