1. A multi-touch interface that allows users to change multiple parameters blindly, comprising:
providing a multi-touch surface that interacts coherently over its whole area, interpreting the vertical and horizontal movement of a variable number of fingers on said multi-touch area to control said parameters, one via the horizontal and one via the vertical direction, enabling the user to control two parameters at the same time via said horizontal and vertical movements without requiring the user to look at the touch surface, changing the parameters to be controlled by said touch-area movement by altering the number of fingers that touch said touch-area without requiring the user to look at the touch surface, allowing a user to control the sensitivity of said multi-touch interface via the movement of his or her fingers while at the same time controlling said parameters, giving some sort of haptic feedback when the user reaches the end of the touch surface, detecting the correct number of fingers on the touch area by implementing a fault-tolerance delay of about 30 ms to ignore accidental taps enabling the user to control four parameters at the same time by quickly alternating between two different numbers of fingers touching the touch area while swiping diagonally across the touch surface providing a method to configure the parameters that can be controlled by each combination of numbers of fingers and touch gesture, providing a method that makes sure the user does not accidentally alter a gesture-parameter mapping and thereby modify the device's behavior while the user is interacting with the device to control said parameters. |
