Head-mounted display system

摘要

A head mounted display system connects a portable information terminal (100) and a head mounted display device (1) to each other through a PC card (200). To the PC card (200) is provided a second connector (204) for supplying power and a signal from the outside which are different from power and a signal from an internal bus of the PC card (200), separately from a first connector (205) of the PC card, and power and a signal to the head mounted display device (1) are collectively supplied by a main cable (66) connected to the first connector (205).
