Abstract:
1. An apparatus for projecting light onto a retina of a viewer, to thereby allow the viewer to perceive a display object via a virtual image, the apparatus comprising: an emitter emitting light; a modulator modulating the light; a display unit outputting the modulated light to the retina of the viewer through an exit of the display unit, to thereby display in an image display region an image representative of the display object in the form of a virtual image, the display unit being mounted on a head of the viewer in operation; a detector detecting a relative position of a to-be-detected segment of a human body of the viewer, with respect to a reference segment of the human body, the to-be-detected segment being selected from a plurality of segments constituting the human body which are displaceable relative to each other, for detection of a motion of the to-be-detected segment, and the reference segment being selected from the plurality of segments for establishment of a reference position related to the human body; and a controller controlling the emitter and the modulator so that the image is displayed in the image display region, the controller performing display control which includes at least one of control of a display/non-display status of the image, and control of a display position of the image, based on the detected relative position.
