Abstract
Discussed herein is an information processing apparatus that detects a touch input at a touch panel disposed on or formed integrally with a display panel, performs sampling of the detected touch position and utilizes a predictive filter to estimate the coordinates of the touch position. The apparatus comprises a controller that actuates the predictive filter based on the application being executed and updates the display panel with the estimated coordinates when a predetermined condition is satisfied.
Claims19
An information processing apparatus comprising:
- a display configured to indicate a display position corresponding to a touch input;
- a touch sensor formed integrally with the display and configured to detect the touch input;
- circuitry configured to
- receive coordinate positions corresponding to the touch input from the touch sensor;
- sample the coordinate positions corresponding to the touch input;
- calculate a motion vector corresponding to the touch input based on the sampling of the coordinate positions of the touch input;
- compute a coefficient estimation parameter for the motion vector based on a predetermined condition;
- and
- control the display to indicate a display position corresponding to a predicted future touch input based on the coefficient estimation parameter.
An information processing method performed by an information processing apparatus, the method comprising:
- displaying a display position corresponding to a touch input;
- detecting a touch input by a touch sensor;
- receiving coordinate positions corresponding to the touch input;
- sampling the coordinate positions corresponding to the touch input;
- calculating a motion vector corresponding to the touch input based on the sampling;
