Claim 1
Independent Claim
71 words
A display apparatus comprising: playing means for displaying image information for an observer; detecting means for detecting a motion of at least a part of the body of said observer; and controlling means for making said displaying means display a display element for input of an operation instruction, and starting a process corresponding to said display element when said detecting means detects a specified motion in correspondence to said display element.
Claim 2
Dependent Claim
18 words
The apparatus according to Claim 1, wherein said display apparatus is mounted on the head of said observer.
Claim 3
Dependent Claim
23 words
The apparatus according to Claim 1, wherein said detecting means has visual axis detecting means for detecting a visual axis of the observer.
Claim 4
Dependent Claim
35 words
