1. A method, comprising:
determining an inter-pupillary distance (IPD) value with a processor from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having a single screen the position sensitive device being configured to produce a signal that corresponds to a distance between the two sighting fixtures; and
digitally warping images by acting on corresponding digital image content according to the IPD value with the processor to optimize display of the images with two fixed optics for the determined IPD value before displaying the images on a display.
