1. A head mounted display, comprising:

  • a pico projector unit;

    an application processor for controlling the pico projector unit to project a virtual image having a virtual object located on a virtual image coordinate in a virtual image coordinate system;

    an eye image sensing unit for capturing an eye image data;

    an adjustment unit;

    a sensing apparatus for sensing a touch object to output a sensing data;

    an application specific integrated circuit (ASIC) for obtaining a real coordinate of the touch object in a real image coordinate system according to the sensing data, wherein the ASIC obtains a pupil position according to the eye image data, controls the adjustment unit to adjust an imaging position of the virtual image according to the pupil position, and determines whether the touch object touched the virtual object according to the pupil position, the real coordinate and the virtual coordinate; and

    a glasses frame for supporting the adjustment unit, the pico projector unit, the application processor, the eye image sensing unit, the real coordinate capturing device and the ASIC.
