TOUCH FILTERING THROUGH VIRTUAL AREAS ON A TOUCH SCREEN
First Claim
1. A touch controller, comprising:
- a touch frame processing component adapted to receive sensor signals containing information about a touch point on a touch screen, the touch frame processing component operable to process the sensor signals to generate touch information associated with each touch point; and
a touch coordinate processing component coupled to receive the touch information from the touch frame processing component, the touch coordinate processing component including virtual area parameters that define a plurality of virtual areas on the touch screen, the touch coordinate processing component operable to identify which one of the plurality of virtual areas contains a current touch point and to report or filter the current touch point as a function of the identified virtual area.

Abstract
According to one embodiment of the present disclosure, a touch controller includes a touch frame processing component adapted to receive sensor signals containing information about a touch point on a touch screen. The touch frame processing component processes the sensor signals to generate touch information associated with each touch point. A touch coordinate processing component is coupled to receive touch information from the touch frame processing component and includes virtual area parameters that define a plurality of virtual areas on the touch screen. The touch coordinate processing component is operable to identify which one of the plurality of virtual areas contains the current touch point and to report or filter the current touch point as a function of the identified virtual area.
