Alternative text entry using different input methods

Published: 23 October 2006 Publication History

Abstract

This paper deals with PC-based alternative (i.e., keyboardfree) text entry and the issues related to emulating keystrokes with only a limited number of input signals. The previously introduced HaMCoS tool tries to enable someone who cannot use the hands to enter text almost as fast as someone exclusively using a manual mouse. To achieve this rather ambitious goal, HaMCoS provides two different (but combinable) solutions. On the one hand, word completion is offered as a shortcut technique. On the other hand, in addition to a mere on-screen keyboard, a completely new application has been implemented where selecting characters is somehow similar to entering Morse code (but with four 'bits' instead of dots and dashes only). In order to show the effect of these measures, the times needed to copy a moderately long text in various circumstances are reported.
