Abstract

A finger-keyed human-machine interface device and methods provide outputs suitable for entering keyed data into a computer, cash register, musical device or other machines. Varying relative positions or orientations of body-attached electrodes generates data. Combinations of connections between electrodes are translated into output signals corresponding to keyed outputs. Levels of connections are used for predictive provisional inputs allowing a user to retract outputs before they are made final and for other applications. Mappings of electrodes attached to fingers and hands are presented for entering keyed data or selecting musical notes.
