you'd need to know where 'Q' was , absolutely , for you to know where "W" , "E" , "R" , "T" and "Y" were relative to that. But pretty cool idea though ...

  Why do you need absolute positions? Just see if the finger tapping the table is extended up/forward relative to other finger(s).

    how would the computer know which key your finger was on to figure out what keys are relative to that finger?
    • amichail 17y ago
      You could assume that the non-thumb fingers of a hand span at most two rows and that one of these is the "home" row. When you detect a tap visually, you could then infer which row that finger tapped by looking at where the other non-thumb fingers are.

        i dont understand , are we still talking about a qwerty keyboard? or a special kind with just two rows, one of which is a "home" row that is placed wherever certain fingers are?

          This would work with three rows, with the home row being the middle one.
