Abstract
A head mounted display and a control method thereof are disclosed. The control method comprises following steps. An application processor controls a 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 captures an eye image data. A sensing apparatus senses a touch object to output a sensing data. An ASIC obtains a real image coordinate of the touch object in a real image coordinate system according to the sensing data. The ASIC obtains a pupil position according to the eye image data, and controls the adjustment unit to adjust an imaging position of the virtual image according to the pupil position. The ASIC determines whether the touch object touched the virtual object according to the pupil position, the real coordinate and the virtual coordinate.
