Abstract

In a body mounting type display system, at least a signal corresponding to display data is outputted to a computer side output transmission circuit through a bus line of a computer, and the data corresponding to the signal is written in a buffer memory of the computer side output transmission circuit by the computer. The data written in the buffer memory is read and sent, and the data is received at a body side output transmission circuit, which is restored to a signal corresponding to the signal outputted through the bus line. An image output interface connected to the body side output transmission circuit produces a signal for actuating a display device worn by a user based on the display data of the restored signal. Thus, there is provided the body mounting type display system suitable for providing information to the user who can work with hand free condition.
