Apparatus and method for virtual retinal display capable of controlling presentation of images to viewer in response to viewer's motion
First Claim
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; and
a controller controlling the emitter and the modulator so that the image is displayed in the image display region, wherein the controller detects a relative motion of the viewer with respect to a position of the viewer by treating the position of the viewer as a position reference for display, and performs 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, in accordance with the detected relative motion.

Abstract
An apparatus is disclosed which projects light onto a retina of a viewer, to thereby allow the viewer to perceive a display object via a virtual image. The apparatus includes: 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; and a controller controlling the emitter and the modulator so that the image is displayed in the image display region. The controller detects a relative motion of the viewer with respect to a position of the viewer, and performs at least one of control of a display/non-display status of the image, and control of a display position of the image, in accordance with the detected relative motion.

29. A method of projecting light onto a retina of a viewer, to thereby allow the viewer to perceive a display object via a virtual image, the method comprising the steps of:
-
emitting light;
modulating the light;
causing a display unit to output 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; and
controlling the emitter and the modulator so that the image is displayed in the image display region, wherein the step of controlling includes;
detecting a relative motion of the viewer with respect to a position of the viewer by treating the position of the viewer as a position reference for display; and
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, in accordance with the detected relative motion.
