METHOD AND SYSTEM FOR DETECTING A FINGER CONTACT ON A TOUCHPAD
First Claim
1. A method for executing a scroll control operation on a touchpad, comprising the steps of:
- detecting a first simultaneous execution of a first operation executed by a first pointing object, and a second operation executed twice in succession by a second pointing object, wherein the first operation includes a presence of the first pointing object on the touchpad, and the second operation includes a contact with the touchpad by the second pointing object, followed by lifting the second pointing object off the touchpad subsequently; and
triggering a scroll control function in response to the detection of the first simultaneous execution of the first operation and the two successive second operations.

Abstract
A method for executing a scroll control operation on a touchpad includes detecting a first simultaneous execution of a first operation executed by a first pointing object, and a second operation executed twice in succession by a second pointing object, wherein the first operation includes detecting a presence of the first pointing object on the touchpad, and the second operation includes contacting with the touchpad by the second pointing object, followed by lifting the second pointing object off the touchpad subsequently. The method further includes triggering a scroll control function in response to the detection of the first simultaneous execution of the first operation and the two successive second operations.

13. A method for executing a scroll control operation on a touchpad, comprising the steps of:
-
predefining at least a first region and a second region on the touchpad, the first region and the second region associated with a first scrolling direction and a second scrolling direction, respectively; detecting a presence of a first pointing object on the touchpad; detecting an operation executed twice in succession by a second pointing object in the presence of the first pointing object, the operation including a contact with the touchpad by the second pointing object, followed by lifting the second pointing object off the touchpad subsequently; and triggering a scroll control function in the respective scrolling direction in response to the detection of the two successive operations. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
