PROBLEM TO BE SOLVED: To obtain an observation device which enables an observer to control a high-presence display by his or her biological reaction by automatically deciding whether the display is used by a person other than the observer and biological reaction recorded as a trigger from biological reaction being observed by making the observer register his or her biological reaction, caused by inputting visual information that can not be obtained from a two-dimensional image so far to the observer's eye, as a password or trigger signal as to a high- presence display (HMD: head-mount display, three-dimensional video presenting device etc.). SOLUTION: The observation device is provided with a display means and an optical means in a housing mounted on the head of the observer and has data on whether the observation device was used and a control mechanism for the display by using certain-time biological reaction that the observer previously registered as an identification signal when the observer observes an image displayed on the display means through the optical means. |
