Patent Images
1. A method of tracking one or more inputs at a touch sensitive surface, comprising:
- detecting one or more touch inputs in a first scanning frame;
for each detected touch input, defining a scanning window around a determined location of the detected touch input;
scanning each defined scanning window, in a second scanning frame, to detect one or more touch inputs;
associating a touch input detected in each scanning window in the second scanning frame with the touch input in the first scanning frame for which the scanning window was defined.
