Adaptive stylus position interpolation

A computing system comprising:

• a touch screen;
• a stylus;
• and
• a stylus position interpolation module configured to:
• evaluate a stylus position function to render a user's stroke of the stylus on the touch screen;
• detect one or more anomalies in the rendered stroke of the stylus;
• adapt the stylus position function to change one or more coefficients of the position function and smooth the one or more detected anomalies;
• and
• evaluate the adapted stylus position function to render a subsequent stroke of the stylus on the touch screen, wherein the detecting, adapting, and evaluating operations are performed in real-time.

One or more tangible processor-readable storage media embodied with instructions for executing on one or more processors and circuits of a device a process comprising:

• evaluating a stylus position function to render a user's stroke of a stylus on a touch screen;
• detecting one or more anomalies in the rendered stroke of the stylus;
• adapting the stylus position function to change one or more coefficients of the position function and smooth the one or more detected anomalies;
• and
• evaluating the adapted stylus position function to render a subsequent stroke of the stylus on the touch screen, wherein the detecting, adapting, and evaluating operations are performed in real-time.
