The finger as a graphical stylus enjoys a coefficient of friction with glass sufficient to provide input of direction and torque as well as position from a single point. This report describes a pressure sensitive digitizer PSD capable of accepting these force inputs, and discusses a set of five simple input applications used to assess the capabilities of this device. These applications include techniques for specifying vectors, and pushing, pulling, dispersing and reorienting objects with a single touch. Experience gained from these applications demonstrates that touch and pressure sensing open a rich channel for immediate and multi-dimensional interaction. The project is an example of basic research with potential for future application. The report will be of interest primarily to research scientists in the field of graphic CRT displays.
