Abstract

An immersive headset device is provided that includes a display portion and a body portion. The display portion may include microdisplays having a compact size. The microdisplays may be movable (e.g., rotational) relative to the body portion and can be moved (e.g., rotated) between a flipped-up position and a flipped-down position. In some instances, when the microdisplays are flipped up, the headset provides an augmented reality (AR) mode to a user, and when the microdisplays are flipped down, the headset provide a virtual reality (VR) mode to the user. In certain implementations, the headset includes an electronics source module to provide power and/or signal to the microdisplays. The electronics source module can be attached to a rear of the body portion in order to provide advantageous weight distribution about the head of the user.

Claims

1. An immersive headset device comprising:

a body portion adapted to be worn on a head of a user;

a display portion attached to a front of the body portion proximate at least one eye of the user to permit viewing of the display portion with the eye of the user, the display portion comprising at least one OLED display comprising a diagonal dimension in a range from 0.5 to 1.5 inches and adapted to display an image having a display resolution of at least 2k×

2k pixels; and

an electronics source module for housing at least one of power and display signal electronics operatively connected to the display portion.

2. The immersive headset of claim 1, wherein the body portion comprises semi-rigid side frame members.

3. The immersive headset of claim 2, wherein the body portion further comprises a strap assembly adapted to connect the semi-rigid side frame members about a rear of the head, the electronics source module forming part of the strap assembly.

4. The immersive headset of claim 3, wherein the electronics source module is shaped to hold the strap assembly in an appropriate location on the head.

5. The immersive headset of claim 1, wherein the display portion further comprises a diopter adjust mechanism and an interpupillary distance adjust mechanism.

6. The immersive headset of claim 5, wherein at least one of the diopter adjust mechanism and the interpupillary distance adjust mechanism is adapted to be adjusted without removing the headset from the head of the user.

7. The immersive headset of claim 1, wherein the at least one OLED display comprises two OLED displays comprising one OLED display proximate each eye of the user.

8. The immersive headset of claim 7, wherein each OLED display is adapted to receive an independent input from the electronics source module.

9. The immersive headset of claim 1, wherein the display portion is adapted to move between an immersed position in which the display is in a line-of-sight of the user and a non-immersed position by rotating with respect to the body portion.

10. The immersive headset of claim 9, further comprising a hinge mechanism adapted to rotate the display portion with respect to the body portion.

11. The immersive headset of claim 9, further comprising a holding structure adapted to maintain the display portion in at least one of the immersed position and the non-immersed position.

12. The immersive headset of claim 11, wherein the holding structure is selected from the group consisting of a spring mechanism, a snap connector, a latch, a catch, a detent, and a ratcheting mechanism.

13. The immersive headset of claim 1, wherein the electronics source module forms a disk shape.

14. The immersive headset of claim 1, wherein the electronics source module is adapted to provide data in both 2D and 3D formats.

15. The immersive headset of claim 14, wherein the electronics source module is adapted to provide the data at up to 4 k resolution at 120 Hz.

16. The immersive headset of claim 1, wherein the electronics source module is adapted to provide at least one of a single and a dual output.

17. The immersive headset of claim 1, wherein the display portion further comprises a co-axial reflective optical system.

18. The immersive headset of claim 1, wherein the display portion further comprises a doublet lens between the OLED display and an eye of the user.

19. The immersive headset of claim 18, wherein the display portion further comprises an external coverglass between the OLED display and the doublet lens.

20. The immersive headset of claim 18, wherein the display portion further comprises a fiber optic face plate disposed between the doublet lens and the eye of the user.

21. A method of configuring an immersive headset device, the method comprising the steps of:

providing a body portion adapted to be worn on a head of a user;

providing a display portion attached to a front of the body portion proximate at least one eye of the user to permit viewing of the display portion with the eye of the user, the display portion comprising at least one OLED display comprising a diagonal dimension in a range from 0.5 to 1.5 inches and adapted to display an image having a display resolution of at least 2k×

2k pixels; and

operatively connecting an electronics source module for housing at least one of power and display signal electronics to the display portion.

22. The method of claim 21, further comprising programming the electronics source module to provide data to the display portion in both 2D and 3D formats.

23. The method of claim 21, wherein the body portion comprises semi-rigid side frame members.

24. The method of claim 23, further comprising interconnecting the semi-rigid side frame members about a rear of the head with a strap assembly, the electronics source module forming part of the strap assembly.

25. The method of claim 21, wherein the at least one OLED display comprises two OLED displays comprising one OLED display proximate each eye of the user.

26. The method of claim 25, further comprising interconnecting each OLED display to the electronics source module with an independent input.

27. The method of claim 21, wherein the display portion is adapted to move between an immersed position in which the display is in a line-of-sight of the user and a non-immersed position by rotating with respect to the body portion.

28. The method of claim 27, further comprising providing a holding structure adapted to maintain the display portion in at least one of the immersed position and the non-immersed position.

29. The method of claim 21, further comprising interconnecting the electronics source module to the display portion with at least one cable.

30. The method of claim 21, wherein the display portion further comprises a doublet lens between the OLED display and an eye of the user.

31. The method of claim 30, wherein the display portion further comprises an external coverglass between the OLED display and the doublet lens.

32. The method of claim 30, wherein the display portion further comprises a fiber optic face plate disposed between the doublet lens and the eye of the user.
