A recurring theme in the hardware of science fiction novels seems to be the "tongue switch"-- usually, but not always, a series of toggle switches actually built into the teeth and activated by various movements of the tongue. While that may venture a bit further into science FICTION than is practical for this discussion, the tongue (and lips) are the most versatile and dexterous parts of the body after the fingers. Has anyone explored the use of these organs for the type of typed communication being discussed? It would seem to me that something like a morse key, held in the mouth and tongued, would both be relatively simple to construct and would represent a signifiacnt increase in speed over, say, a head-mounted pointing stick for a quadrapalegic. --Chris
