I'm making a mouseless 3dmousepad. The only moving part is your hand. Just as we went from horse to horse-and-carriage, and then to horseless carriage, perhaps we'll go from mouse, to mouse with mousepad, to mouseless mousepad.

Here is a 3d mouse demo. You control the yellow hand by moving your hand around above the table. You can grab the yellow cube, move it around, and set it down somewhere else. Graphics by Barrett.

This shows your hand above some electrodes. The electrodes can be hidden under the table.
