Abstract

An extended reality (XR) head-mounted display (HMD) device may include a processor, a memory device, a power management unit, an HMD video display to present to a user an extended reality image of an environment, and an HMD housing fitted to be formed around a user's eyes. The HMD housing includes an HMD shield, an HMD hood comprising a fabric shroud operatively coupled to a shroud frame and a face mask operatively coupled to the shroud frame to interface with a suer's face and the HMD hood operatively coupled to the HMD shield.

First claim

What is claimed is:

1. An extended reality (XR) head mounted display (HMD) device comprising:
a processor;
a memory device;
a power management unit;
an HMD video display of the HMD device to present to a user an extended reality image of an environment; and
an HMD housing fitted to be formed around a user's eyes, the HMD housing including an HMD shield having the HMD video display mounted therein;
an HMD hood comprising a fabric shroud operatively coupled to a shroud frame and a face mask operatively coupled to the shroud frame to interface with a user's face, where the fabric shroud extends from the face mask on the shroud frame to a distal aperture of the shroud frame operatively coupled to the HMD shield; and
the HMD hood operatively coupled to the HMD housing via fitting the HMD shield into the distal aperture, distal relative to the user's face, in the shroud frame of the HMD hood.

2. The XR HMD device of claim 1 further comprising:
a hood tooth formed on a first edge around the distal aperture of the shroud frame into which the HMD housing is fitted, the hood tooth to operatively couple the HMD hood to the HMD shield via being seated in a shield slot formed in the HMD shield.

3. The XR HMD device of claim 1 further comprising:
a shroud seal formed around the distal aperture along a first edge of the shroud frame to interface with a shield groove formed on the HMD shield, the shroud seal to make an interior of the HMD hood lightproof when installed on the HMD housing.

4. The XR HMD device of claim 1 further comprising:
the fabric shroud including:
a first layer including directionally-oriented moisture wicking fibers;
a second layer including fibers woven in a first direction; and
a third layer including fibers woven in a second direction different from the first direction.

5. The XR HMD device of claim 1 further comprising:
the shroud frame being made of a pliable material, the shroud frame including a set of hood teeth that engage with a plurality of shield slots in the HMD shield by elastically bending the shroud frame over the HMD shield and into the plurality of shield slots when the HMD shield is inserted into the distal aperture in the shroud frame of the HMD hood.

6. The XR HMD device of claim 1 , wherein the face mask is made of silicone.

7. The XR HMD device of claim 1 , wherein the fabric shroud is welded onto the shroud frame along a fabric shroud perimeter formed on the shroud frame.

8. The XR HMD device of claim 1 , wherein the shroud frame is made of a pliable plastic that bends to conform to a user's face when the HMD device is worn.

9. The XR HMD device of claim 1 further comprising:
a frame bead formed along a proximal edge of the shroud frame facing the user, the frame bead to interface with a bead channel formed in the face mask to mount the face mask on the shroud frame.

10. A head mounted display (HMD) hood operatively coupled to an extended reality (XR) HMD device having an HMD shield comprising:
a shroud frame operatively coupled to the HMD shield, having a front distal aperture, and including a hood tooth formed on a first edge of the front, distal aperture of the shroud frame to operatively couple with a shield slot formed into the HMD shield of the HMD device;
a fabric shroud operatively coupled across the shroud frame from a proximal aperture of the shroud frame to the front, distal aps of the shroud frame, the fabric shroud including a plurality of fabric layers to wick moisture and block light from an HMD video display formed in the HMD shield of the HMD device that is operative coupled within the front, distal aperture of the shroud frame of the HMD hood; and
a face mask operatively coupled to the shroud frame.

11. The HMD hood of claim 10 further comprising:
a shroud seal formed on the first edge of the shroud frame along the front, distal aperture to operatively couple with a shield groove formed on the HMD shield, where the shroud seal prevent light leaking into an interior of the HMD hood.

12. The HMD hood of claim 10 further comprising:
the shroud frame being made of a pliable material, wherein the hood tooth is operatively coupled with a shield slot formed into the HMD shield of the HMD device by elastically bending the shroud frame over the HMD shield and into the shield slot.

13. The HMD hood of claim 10 , wherein the fabric shroud is welded or adhered onto the shroud frame along a fabric shroud perimeter formed on the shroud frame.

14. The HMD hood of claim 10 further comprising:
a frame bead formed along a second edge of the shroud frame around a proximal aperture facing a user, the frame bead to interface with a bead channel formed in the face mask.

15. The HMD hood of claim 10 further comprising:
the plurality of fabric layers including:
a first layer including directionally-oriented moisture wicking fibers;
a second layer including fibers woven in a first direction; and
a third layer including fibers woven in a second direction different from the first direction.

16. An extended reality (XR) head mounted display (HMD) device comprising:
a processor;
a memory device;
a power management unit;
an HMD device to present to a user an extended reality image of an environment via an HMD video display mounted within an HMD shield;
the HMD shield fitted into an HMD hood to be formed around a user's eyes;
the HMD hood including:
a shroud frame including a hood tooth formed on a first edge around a front, distal aperture of the shroud frame to couple with a shield slot formed into the HMD shield of the HMD device;
a fabric shroud operatively coupled across the shroud frame from a proximal aperture of the shroud frame to a front, distal aperture of the shroud frame to receive the HMD shield, the fabric shroud including a plurality of fabric layers to wick moisture and block light from the HMD video display in the HMD shield of the HMD device installed within the HMD hood; and
a face mask operatively coupled to the shroud frame; and

an adjustable strap mounted to the HMD shield to fit around a user's head.

17. The XR HMD device of claim 16 , further comprising:
the plurality of fabric layers including a first layer including directionally-oriented moisture wicking fibers.

18. The XR HMD device of claim 16 , further comprising:
a shroud seal formed on the shroud frame to interface with a shield groove formed on the HMD shield, the shroud seal to prevent light from leaking into an interior of the HMD hood.

19. The XR HMD device of claim 16 , further comprising:
the plurality of fabric layers including:
a first layer including fibers woven in a first direction; and
a second layer including fibers woven in a second direction different from the first direction.

20. The XR HMD device of claim 16 , further comprising:
a frame bead formed along a second edge of the shroud frame around a proximal aperture of the shroud frame to face the user, the frame bead to interface with a bead channel formed in the face mask to operatively couple the face mask to the shroud frame.
