Abstract

There is provided an information processing apparatus which occupies a small space and which is capable of supplying image information having high definition and high resolution. An information processing apparatus of the invention employs a head mount display (HMD) utilizing compact flat panel displays as a display device for displaying information. The use of a head mount display as the display device of the information processing apparatus prevents any reduction in a work space. It also makes it possible to change the size of a virtual display screen freely. In addition, the information processing apparatus of the invention is capable of displaying a plurality of pieces of information on the virtual display screen at a time.
