Abstract

Claims (52)

1 . A head-mounted display system, comprising:

a head-mounted display unit; and

a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use, the head-mounted display unit comprising an interfacing structure constructed and arranged to be in opposing relation with the user's face,

wherein the interfacing structure comprises a resilient and flexible face engaging portion having a curved cross-section,

wherein the face engaging portion comprises an anterior portion extending in a radially outward posterior direction, curving around into a posterior portion extending in a radially inward posterior direction, wherein a posterior facing surface of the posterior portion provides a user contact surface,

wherein the face engaging portion comprises at least one closed loop portion having an enclosed cross-section, and

wherein:

the face engaging portion comprises a first closed loop portion and a second closed loop portion;

the first closed loop portion and the second closed loop portion are provided on respective sides of the user's nose in use; and

the first closed loop portion and the second closed loop portion are provided proximate the user's cheeks in use.

2 . The head-mounted display system of claim 1 , wherein the face engaging portion is configured such that the posterior portion is biased towards engagement with the user's face, in use.

3 . The head-mounted display system of claim 1 , wherein the face engaging portion bends around and overlaps itself to provide the at least one closed loop portion.

4 . The head-mounted display system of claim 1 , wherein the face engaging portion comprises a plurality of regions, each of the plurality of regions having a respective cross-sectional thickness, and wherein the face engaging portion comprises a forehead portion, two cheek portions, and two side portions proximate the user's sphenoid regions in use and connecting the forehead portion to the respective cheek portions.

5 . The head-mounted display system of claim 4 , wherein the plurality of regions of the face engaging portion comprises:

a first region extending around an inner periphery of the face engaging portion;

a second region extending around an outer periphery of the face engaging portion;

a third region extending around the inner periphery of the face engaging portion, positioned between the first region and the second region;

fourth regions in each cheek portion, bounded by the first region and the third region.

6 . The head-mounted display system of claim 5 , wherein the first region comprises a posterior forehead portion in the forehead portion, extending in a superior direction from the inner periphery of the face engaging portion.

7 . The head-mounted display system of claim 5 , wherein the third region comprises a superior forehead portion in the forehead portion, extending over a centre of the forehead portion into an anterior forehead portion.

8 . The head-mounted display system of claim 7 , wherein the second region comprises superior lateral portions, each extending from a respective side portion towards the superior forehead portion, and/or wherein the second region comprises an outer periphery forehead portion.

9 . The head-mounted display system of claim 5 , wherein the first region has a greater thickness than the fourth regions, the fourth regions have a greater thickness than the third region, and/or the third region has a greater thickness than the second region.

10 . The head-mounted display system of claim 5 , wherein a width of the first region in an anterior-posterior direction is greater through the forehead portion than at the cheek portions or the side portions, and/or wherein a width of the second region in an anterior-posterior direction is greater through the forehead portion than at the cheek portions.

11 . A head-mounted display system, comprising:

a head-mounted display unit; and

a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use, the head-mounted display unit comprising an interfacing structure constructed and arranged to be in opposing relation with the user's face,

wherein the interfacing structure comprises a resilient and flexible face engaging portion having a curved cross-section,

wherein the face engaging portion comprises an anterior portion extending in a radially outward posterior direction, curving around into a posterior portion extending in a radially inward posterior direction, wherein a posterior facing surface of the posterior portion provides a user contact surface,

wherein the face engaging portion comprises at least one closed loop portion having an enclosed cross-section, and

wherein the face engaging portion comprises a base portion and a loop portion comprising a loop flange, wherein the loop flange overlaps the base portion to provide the closed loop portion.

12 . The head-mounted display system of claim 11 , wherein:

the loop portion extends from an anterior position to a posterior position;

a cross-section of the loop portion tapers off between the anterior position and the posterior position; and

the loop portion includes an arcuate portion between the anterior position and the loop flange.

13 . The head-mounted display system of claim 11 , wherein the loop flange overlaps an anterior facing surface of the base portion.

14 . The head-mounted display system of claim 11 , wherein the loop flange is secured to the base portion.

15 . The head-mounted display system of claim 11 , wherein the base portion and the loop portion are integrally formed as a single component.

16 . A head-mounted display system, comprising:

a head-mounted display unit; and

a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use, the head-mounted display unit comprising an interfacing structure constructed and arranged to be in opposing relation with the user's face,

wherein the interfacing structure comprises a resilient and flexible face engaging portion having a curved cross-section,

wherein the face engaging portion comprises an anterior portion extending in a radially outward posterior direction, curving around into a posterior portion extending in a radially inward posterior direction, wherein a posterior facing surface of the posterior portion provides a user contact surface,

wherein the interfacing structure comprises a light-blocking nasal portion spanning between cheek portions of the face engaging portion,

wherein the light-blocking nasal portion comprises a pronasale portion extending radially and in a superior direction over the pronasale of the user's nose, and

wherein the light-blocking nasal portion further comprises a first bridge portion and a second bridge portion extending in a superior direction from the pronasal portion, the first bridge portion and the second bridge portion having a slot therebetween, the slot extending from a posterior edge of the light-blocking nasal portion towards the pronasale portion, and wherein the first bridge portion and the second bridge portion are configured to rest on respective sides of the user's nose bridge in use.

17 . A head-mounted display system, comprising:

a head-mounted display unit; and

a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use, the head-mounted display unit comprising an interfacing structure constructed and arranged to be in opposing relation with the user's face,

wherein the interfacing structure comprises a resilient and flexible face engaging portion having a curved cross-section,

wherein the face engaging portion comprises an anterior portion extending in a radially outward posterior direction, curving around into a posterior portion extending in a radially inward posterior direction, wherein a posterior facing surface of the posterior portion provides a user contact surface,

wherein the interfacing structure comprises a foam cushion, wherein the posterior portion extends over the foam cushion, and

wherein the face engaging portion comprises a cushion support flange extending from a radially inwardly facing surface of the face engaging portion, and wherein the foam cushion is provided between the cushion support flange and the posterior portion.
