Abstract

The authors described in an earlier paper a versatile electronic control system for wheelchairs. This paper describes a plug-in conversion to the original controller so that high-level quadriplegics (c4 and above) can completely control a wheelchair by humming four notes of the musical scale. Forward-stop-reverse, right-turn and left-turn functions are provided through the use of tone decoders. The control system is designed so that the frequencies to which it respons are easily adjustable to match users' vocal characteristics.
