why is there no "typing glove?" some kind of device that is attached to your hand that tracks the minute movement of your fingers, and translates them into keystrokes? the amount of physical movement for each keystroke would be dramatically reduced and so it would be faster as well. even without going this far, wouldnt it be much faster to have a keyboard where there is only one button for each finger, and combinations of depressions map to keys? that way you would never have to move your fingers more than is necessary.
