1. An information handling system comprising:

  • a processor operable to process information for presentation to a user as visual images;

    memory interfaced with the processor and operable to store the information;

    a graphics system interfaced with the processor and memory, the graphics system operable to generate the visual images at one or more display devices;

    a projector interfaced with the graphics system and operable to project the visual images at the projection surface;

    a detection device operable to detect end user inputs made at the visual images proximate the projection surface, the detection device detecting a first type of physical condition;

    an accelerometer operable to detect accelerations at the projection surface that result from impact of an object at the projection surface;

    a touch input module interfaced with the graphics system and detection device, the touch input module operable to determine an end user input at the visual image based upon a detection by the detection device at a detection location; and

    a touch input verifier interfaced with the touch input module and operable to apply a predetermined sensed condition different from the first type of physical condition to verify that the detection by the detection device at the detection input is a touch input, the touch input verifier disambiguating verified touches as inputs to the detection device from unverified touches as unintended to be inputs;

    wherein the predetermined sensed condition includes at least an acceleration caused by impact on the projection surface; and

    wherein the touch input verifier interfaces with the accelerometer and analyzes the accelerations to determine the predetermined sensed condition of a physical impact at the projection surface.
