ANCHOR-DRAG TOUCH SYMBOL RECOGNITION

摘要

Described herein are methods and devices that employ a predefined class of anchor-drag touches to minimize host processor use in a mobile computing device. As described, detecting anchor-drag touch gestures enables the touch screen controller to handle a large portion of touch processing, even in mobile devices with larger displays. A first touch establishes an anchor area, from which a drag area is calculated, and a second touch within the drag area provides a command to the device. Some embodiments may limit subsequent touch processing to the identified drag area.

1. A system configured to recognize multitouch gestures, the system comprising:
a touch panel; a touch detection module configured to capture a first touch event and a second touch event on the touch panel; and a processing module configured to determine if the second touch event is within a predefined boundary area from the first touch event, and discard the touch event if it is outside of the predefined boundary, the processing module further configured to track a position of a touch event within the predefined boundary and activate a predetermined object drag process based on the position of the touch event.
