mind mouse
<hardware> A {pointing device} (unlike a {mouse} in design,
but serving the same purpose) which works via sensors in
contact with the user's skin. The sensors are built into a
plastic base which fits on one finger and which is similar in
shape to a finger cast.
The principle of operation is presumably myoelectric, not
psionic, contrary to what the name implies.
As of the time of writing (1996), mind mice are not accurate
enough to be anything but novelties.
