Presentation of a haptic human computer interface (HCI) utilizing tongue input, developed for users with severe disabilities. The device uses three inductive sensors and is passive, as it does not require insertion of an electrically-powered sensor into the mouth. The sensors are placed inside a square stainless-steel case with a hole for the tongue. The sensors send analogue output signals to a data acquisition system, which maps the signals to a certain command or task. The mapping results can then be used for various computer applications. A pre-clinical experiment with the HCI was conducted using a 21-year-old able-bodied participant, who used the interface for keyboarding and mouse tracking. For external applications, commands can be sent through the analogue or digital output of a data acquisition board (DAQ) in the computer to control everyday electrical devices or appliances. The authors report that further clinical trials will be required to test the HCI on disabled persons before it is ready for future commercial development.
