We present a set of interaction techniques that make novel use of a small pressure-sensitive pad to allow one-handed direct control of a large number of parameters. The surface of the pressure-sensitive pad is logically divided into four linear strips which simulate traditional interaction metaphors and the functions of which may be modified dynamically under software control. No homing of the hand or fingers in needed once the fingers are placed above their corresponding strips. We show how

Due to the compact size of the device and the method of interaction, which does not rely on on-screen widgets or the 2D navigation of a cursor, the versatile input system may be used in applications, where it is advantageous to minimize the amount of visual feedback required for interaction.
