Digitizer for geometrical position measurement of pointing device, has mutilating surface whose electrostatic fields are analyzed when mutilated to invoke functions e.g. cursor movements, in visual form as flying buttons

摘要

The digitizer has a mutilating surface whose electrostatic fields are mutilated by a flexible, metallic, electrically conducting material provided at the head of a pointing device (3). The head is made of flexible material e.g. rubber. The mutilated fields are analyzed to invoke functions e.g. macro-program, text inputs, release acoustic tones, create mouse instructions, cursor movements, in visual form as flying buttons.
