Smoothing of touch input

A method of smoothing touch input, the method comprising:

• calculating a second order expected window of touch event positions using a previous three touch event positions;
• determining if a current raw touch event position is within the second order expected window of touch event positions;
• and
• if the current raw touch event position is within the second order expected window of touch event positions, returning a distance-agnostic smoothed position that is based on the current raw touch event position and a last-returned position;
• and
• if the current raw touch event position is outside the second order expected window of touch event positions, determining if a set of most recent raw touch event positions have remained outside the second order expected window of touch event positions for longer than a tolerated duration;
• then
• if the set of most recent raw touch event positions have not remained outside the second order expected window of touch event positions for longer than the tolerated duration, returning a last-returned position;
• or
• if the set of most recent raw touch event positions have remained outside the second order expected window of touch event positions for longer than the tolerated duration, returning a distance-influenced smoothed position based on the current raw touch event position, a last-returned position, and a distance between the current raw touch event position and the last-returned position.

A computing system, comprising:

• a touch display;
• an input module to recognize a touch event position of a touch input directed to the touch display;
• a distance-agnostic module to return a distance-agnostic smoothed position if a current raw touch event position is within an expected window of touch event positions;
• and
• a distance-influenced module to return a distance-influenced smoothed position if the current raw touch event position is outside the expected window of touch event positions for longer than a tolerated duration, the distance-influenced smoothed position being based on a distance between the current raw touch event position and a last-returned position.
