Abstract
A notebook computer which is controlled by a stylus executing gestures on the computer screen. The stylus and the computer include complementary electronic circuitry by which the proximity of the stylus tip to the computer is sensed. The proximity sensing is used to detect to approach of the stylus tip to the computer screen, and gestural commands are then entered on the screen by moving the stylus. The entry of a command is terminated by removing the stylus tip from proximity with the screen, which is detected by the computer, which then implements the command. Alternative methods of implementing the commands include time-outs and command termination buttons.
