Mouse pen gets joyful mobile twist

Inventor C.L. Chung claims he has made a breakthrough in pointing devices for mobile phones and other Net appliances. The system which, includes a mouse device, an electronic pen and a joystick, will fit in a 3 cm by 2 cm area and will work with mobile phones, keyboards for Internet TVs, gaming controllers and PDA style devices, claimed Chung. The switch does not use a stylus and instead relies on movements in all directions and can also be used to input text, Chung claims. Chung has also invented two other devices using the position encoder system he is patenting. The invisible cord mouse eliminates connecton cords, while mouse board actually uses a moving keyboard to simulate mouse movements. There's a diagram and simulations of Chung's developments at this web page. ®
