<p>PROBLEM TO BE SOLVED: To provide an input system capable of conveniently, quickly and reliably performing an input operation without using an input device, a voice input device, etc., which are of a large size. SOLUTION: This system forms a previously defined symbol image at a fixed position in the visual field of an operator 10 in such a manner that an optical system 12b arranged a fixed position with respect to the operator 12 and an image display light emitting means 2 changes the optical path of image display light L. The combiner 16 of the system 12b transmits light from the position where the symbol image is formed. An indicator 22 for a position instruction that can be moved by the operator is arranged at the position where the symbol image is formed. The system detects the relative position of the indicator 22 to the symbol image and outputs an input signal corresponding to the detected relative position of the indicator 22 by the operation of a switch 21 by the operator 10.</p> |
