This paper introduces a single-key text entry application for users with severe physical impairments. The tool combines the idea of a
scanning ambiguous keyboard
(which promises unusually high entry rates) with
intentional muscle contractions
as input signals (which require much less physical effort compared to key presses). In addition to the program architecture, the paper presents the results of several evaluations with participants with and without disabilities. An entry speed of 6.59 wpm was achieved.
