TWO-TOUCH GESTURE DETECTION ON A FOUR-WIRE RESISTIVE TOUCHSCREEN |
摘要 |
Embodiments of a touchscreen control device and associated method of operation enable two-touch gesture detection on a four-wires resistive touchscreen. Illustrative devices and methods enable detection when a resistive touchscreen is touched in two separate points. Embodiments of an electronic circuit can comprise a controller configured for coupling to a four-wires resistive touchscreen and at least two resistors. The controller can be further configured to detect multiple touches on the four-wires resistive touchscreen and measure zoom gestures comprising measuring distances between two-touches and obtaining angle of rotation and total distance between the two-touches.
