The information rate in bits was almost constant over a wide range of difficulty conditions, when tapping a stylus back and forth.

Plots of bit rate versus task difficulty revealed a remarkably constant bit rate over a wide range of conditions.

The task was to tap back and forth between two metal strips with a stylus. The degree of difficulty was varied by varying the width, spacing and stylus weight. Plots of bit rate versus task difficulty revealed a remarkably constant bit rate over a wide range of conditions.
