Abstract: A method for reporting touch on a touchscreen includes detecting first touch data from the touchscreen corresponding to a first touch on the touchscreen; determining coordinates of the first touch from the first touch data; reporting the coordinates of the first touch at a first time; determining predicted coordinates of a second touch based on a linear regression of historical touch data; and reporting the predicted coordinates of the second touch at a second time, where the second time occurs after the first time.

Abstract: A method for operating an electronic device includes detecting, by a touchscreen controller, a touch point on a touchscreen; determining, by the touchscreen controller, coordinates of the touch point; scaling, by the touchscreen controller, up the coordinates of the touch point to obtain scaled up coordinates by overwriting a reserved portion of a touch event protocol with additional information corresponding to the coordinates of the touch point; reporting, by the touchscreen controller, the scaled up coordinates of the touch point to an application processor; and determining, by the application processor, the coordinates of the touch point with an increased resolution by converting the scaled up coordinates into a floating point value.
