HEAD-MOUNTED DISPLAY APPARATUSES
First Claim
1. A head-mounted display apparatus, comprising:
- a reflective microdisplay;
a visible light source configured to illuminate the microdisplay;
an illumination optics unit configured to direct visible light emanated from the visible light source into the microdisplay, and allow light reflected from the microdisplay in the form of an image to pass therethrough and transmit along an optical axis;
an imaging optics unit configured to project the image from the microdisplay into an eye of a user; and
an eye tracker module, comprising;
an invisible light source configured to emanate an invisible light beam into the illumination optics unit, the illumination optics unit configured to reflect the invisible light beam along said optical axis, the imaging optics unit configured to receive and direct the invisible light beam into the eye of the user; and
a sensor configured to receive the invisible light beam reflected back from the eye of the user and to capture an image of the eye.

Abstract
A head-mounted display apparatus is disclosed, the apparatus includes a reflective microdisplay, a visible light source, an illumination optics unit, an imaging optics unit and an eye tracker module which includes an invisible light source and a sensor. The invisible light source emanates an invisible light beam which is subsequently received by the imaging optics unit and directed thereby into an eye of a user. The sensor receives the invisible light beam reflected back from the eye of the user and thereby captures an image of the eye, on the basis of which, a position of the eye is determinable by calculation. The apparatus has the advantage of an improvement in the accuracy of the object tracking and does not have influence on the user at all.

12. A head-mounted display apparatus, comprising:
-
a reflective microdisplay; a visible light source configured to illuminate the microdisplay; a first illumination optics unit configured to direct visible light emanated from the visible light source into the microdisplay, and allow light reflected from the microdisplay in the form of an image to pass therethrough along an optical axis; a second illumination optics unit disposed downstream to the first illumination optics unit along said optical axis and allowing the image from the microdisplay to pass therethrough; an imaging optics unit configured to project the image from the microdisplay into an eye of a user; and an eye tracker module, comprising; an invisible light source configured to emanate an invisible light beam into the second illumination optics unit, the second illumination optics unit configured to reflect the invisible light beam along said optical axis, the imaging optics unit configured to receive and direct the invisible light beam into the eye of the user; and a sensor configured to receive the invisible light beam reflected back from the eye of the user and to capture an image of the eye. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A head-mounted display apparatus, comprising:
-
a transmissive microdisplay; a visible light source configured to illuminate a back of the microdisplay, such that light in the form of an image is transmitted from a front of the microdisplay along an optical axis; an illumination optics unit configured to receive and allow the image from the microdisplay to pass therethrough; an imaging optics unit configured to project the image from the microdisplay into an eye of a user; and an eye tracker module, comprising; an invisible light source configured to emanate an invisible light beam into the illumination optics unit, the illumination optics unit configured to reflect the invisible light beam along said optical axis, the imaging optics unit configured to receive and direct the invisible light beam into the eye of the user; and a sensor configured to receive the invisible light beam reflected back from the eye of the user and to capture an image of the eye. - View Dependent Claims (24, 25, 26)
