TOUCHPAD USING A COMBINATION OF TOUCHDOWN AND RADIAL MOVEMENTS TO PROVIDE CONTROL SIGNALS
First Claim
Patent Images
1. A method for changing at least one control parameter by using a touchpad, said method comprising the steps of:
- 1) providing a circular touchpad that is capable of detecting and tracking movement of a pointing object along a surface thereof, wherein the touchpad has at least one region that controls input for at least one control parameter;
2) performing touchdown of a pointing object in a center area of the touchpad; and
3) moving the pointing object from the center area towards an outer perimeter of the at least one region to thereby change the at least one control parameter.

Abstract
A physical or virtual circular touchpad that may have an active touch-sensitive surface in a center area of the touchpad, wherein touchdown in the center area is detected by the touchpad having an active touch-sensitive surface, and then radial movement from the center area towards a perimeter of the circular touchpad and in a specific direction will cause a change in the value of a control parameter.

12. A method for increasing or decreasing the value of at least one control parameter by using a touchpad, said method comprising the steps of:
-
1) providing a circular touchpad that is capable of detecting and tracking movement of a pointing object along a surface thereof, wherein the touchpad has a plurality of regions, each region controlling the value of at least one control parameter, wherein in a first mode of operation the circular touchpad operates in a general purpose mode that performs common touchpad functions, wherein in a second mode of operation the circular touchpad operates in a mode that is dedicated to increasing or decreasing the value of the at least one control parameter; 2) performing touchdown of a pointing object in a center area of the touchpad; and 3) moving the pointing object from the center area towards an outer perimeter of one of the plurality of regions to thereby increase or decrease the at least one control parameter. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A touchpad for changing at least one control parameter, said touchpad comprised of:
-
a circular touchpad that is capable of detecting and tracking movement of a pointing object along a surface thereof; at least one region that controls input for at least one control parameter; means for tracking movement of a pointing object from a center area of the circular touchpad to an outer perimeter; and means for changing a value of the at least one control parameter in accordance with firmware that equates movement within the at least one region to the changing of the value of the at least one control parameter.
