Alternative text entry using different input methods

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.
