PROBLEM TO BE SOLVED: To provide a device for adding a new function 'posture angle detection function' to a head mount display which is an existing device in order to solve the problems with the conventional head mount display for virtual reality integrated with the posture angle detector, such as a high cost, the large scale of the device itself, which is often the case, and consequently a difficulty in the popularization thereof to general consumers. SOLUTION: The posture angle detector may be added to the head mount display device which is set extremely high in a cost zone and in virtual reality technology a sure presence feel may be add thereto. Since function extension is inexpensively made possible, the popularization of the virtual reality technology to the general consumer levels may be prospected, by which the activation to fields, such as video industry, entertainment industry and electronic industry, may be expected.
