TRACKING TOUCHPAD TOUCH INPUT

This abstract first appeared for US patent application 18537373 titled 'TRACKING TOUCHPAD TOUCH INPUT

Original Abstract Submitted

A computing device comprises a touch sensing touchpad, a processor, and memory storing instructions to detect contacts at the touchpad over a plurality of frames of data. At each frame a measured coordinate and a current plurality of characteristics of the contacts are determined. The current plurality of characteristics of a current frame are compared to characteristics of an immediately prior frame. Where at least one of the comparisons satisfies a corresponding threshold, a coordinate jump is detected between the current frame and the immediately prior frame. Based at least on detecting the coordinate jump, a current frame intermediate coordinate value is set to an immediately prior frame intermediate coordinate value of the immediately prior frame, and a smoothing filter is applied to the immediately prior frame intermediate coordinate value to generate a smoothed immediately prior frame intermediate coordinate value, which is outputted.
