1. A device, comprising:

  • a display;

    a processor;

    a storage containing instructions;

    wherein the instructions cause the processor to;

    develop a point cloud representing a pointing object in proximity to or in contact with the display;

    select a set of points from the point cloud;

    determine the selected set of points as control points of a computational smooth surface representing the pointing object;

    determine a point nearest to the display on the computational smooth surface;

    based on the point nearest to the display, determine a point in a direction of a gradient of a curvature of the computational smooth surface; and

    report the point as a location of a desired pointing or touch action.
