1. An optical navigation system comprising:

  • a resolution switching engine to set a resolution status based on a motion speed of a tracking surface relative to an optical finger navigation sensor, wherein the motion speed is a measure of motion data over time;

    a surface detection engine coupled to the resolution switching engine, the surface detection engine to set a surface detection status based on the present resolution status that is set by the resolution switching engine; and

    a navigation engine coupled to the surface detection engine, the navigation engine to read the motion data from the navigation sensor and to report the motion data to a computing device according to the present surface detection status that is set by the surface detection engine.
