<p>Disclosed is a system to input computer commands by touching, tapping or scrolling on a trackpad, touchscreen or similar device with designated finger combinations, using either multiple fingers simultaneously or a single finger. The computer determines which of the user’s fingers have tapped the trackpad, touchscreen or similar device in order to recognize and process commands. The finger determination is achieved by registering the relative positions of a user’s fingers in an initial calibration in which the user taps the index fingers, middle fingers, ring fingers and little fingers of both hands on the trackpad, touchscreen or similar device from which the computer uses the location of the touchpoints to establish the initial location of each finger. The computer then continually detects changes of the positions of a user’s fingers, while the user enters input, from the change in the location of touchpoints and uses both the information about the location of touchpoints computed in the initial calibration and information about the location of touchpoints computed in subsequent taps to determine which of the user’s fingers have tapped the trackpad, touchscreen or similar device in order to recognize and process commands.</p> |
