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;
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.

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.

4. 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, 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, and activates the display control, upon satisfaction of the motion of the viewer with a predetermined condition, based on the detected relative.

7. 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 that; controls the emitter and the modulator so that the image is displayed in the image display region; 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; uses, for allowing the viewer to perceive the image in the image display region, (a) a definition coordinate system for use in defining the display object, and (b) a display coordinate system for use in defining the image to be displayed in the image display region, the display coordinate system being fixed with respect to the display unit; detects a relative relationship between a position and an orientation of the head of the viewer and a reference coordinate system which is predetermined so as to be related to the human body; converts definition data which defines the display object with respect to the definition coordinate system, into display data for displaying the image with respect to the display coordinate system, so as to reflect the detected relative relationship; and controls the emitter and the modulator based on the display data. - View Dependent Claims (8, 9, 10, 11, 12, 13)

28. 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 by an emitter; modulating the light by a modulator; 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; 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; controlling the emitter and the modulator so that the image is displayed in the image display region; 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, based on the detected relative position.
