DISPLAY LATENCY COMPENSATION RESPONSIVE TO AN INDICATOR OF AN IMPENDING CHANGE IN A HAND-INITIATED MOVEMENT
Abstract:
Described embodiments include an apparatus and a method. In an apparatus, a tracking circuit detects a segment of a path defined by a user contact point moving across a touch sensitive display. A filter predicts a next contiguous segment of the path defined by the user contact point in response to an adaptively learned motion parameter. The adaptively learned motion parameter is based on at least two previous instances of the determined motion parameters respectively descriptive of a motion of a user contact point during its movement across the touch sensitive display. A compensation circuit initiates a display by the touch sensitive display of the detected segment of the path and the predicted next contiguous segment of the path. An updating circuit updates the detected segment of the path and the predicted next contiguous segment of the path as the user contact point moves across the touch sensitive display.
