A computing device comprises a touchpad, a processor, and a memory storing instructions executable by the processor to track a contact on a touchpad. A measured velocity and a measured force of the contact on the touchpad are determined. The measured velocity is normalized to a normalized velocity and the measured force of the contact is normalized to a normalized force. Based at least in part on the normalized velocity and the normalized force, a reported position of the contact on the touchpad is temporarily frozen.

Tracking touchpad contacts

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.

Tracking touchpad touch input

Computing devices, touchpads, and related methods for adjusting a force threshold for touch input on a touchpad are disclosed. In one example, a computing device comprises a force sensing touchpad, a processor, and a memory storing instructions executable by the processor to receive a first contact on the touchpad. An area of touch of the first contact is determined, and an adjusted force threshold for touch input is determined based at least on the area of the touch. A second contact is received on the touchpad, and a touch force of the second contact is determined. Based at least on determining that the touch force exceeds the adjusted force threshold, a touch input on the touchpad is registered.
