Abstract

We have conducted three related experiments in order to analyze the performance of the index finger as a pointing device. The results indicate that the performance of the index finger is significantly better as a direct pointing device [1] than as an indirect pointing device using an isometric finger-controlled joystick (Trackpoint). We included a mouse as a "control" condition and in two of the three experiments, the mouse and the finger exhibited similar performance.
