Abstract

Virtual reality (VR) systems and related methods are provided. A representative VR system includes: content detection circuitry configured to determine a type of VR content from among inside-out VR content and outside-in VR content; and processor circuitry configured to execute instructions to display the VR content in accordance with the type of VR content determined. A representative method includes: determining a type of VR content provided to a head mounted display from among inside-out VR content and outside-in VR content; and displaying the VR content to the user with the head mounted display in accordance with the type of VR content determined such that, if the VR content is determined to be inside-out VR content, the head mounted display displays the inside-out VR content, and if the VR content is determined to be outside-in VR content, the head mounted display displays the outside-in VR content.

First claim

What is claimed is:

1. A virtual reality (VR) system for displaying VR content to a user, the system comprising:
content detection circuitry configured to determine a type of VR content from among inside-out VR content and outside-in VR content, wherein the content detection circuitry is further configured to provide a content detection signal based on the type of VR content determined;
processor circuitry configured to execute instructions to display the VR content in accordance with the type of VR content determined; and
switching circuitry configured to switch, responsive to the content detection signal, between an inside-out mode, in which the processor circuitry executes instructions to display inside-out VR content and, an outside-in mode, in which the processor circuitry executes instructions to display outside-in VR content.

2. The system of claim 1 , wherein:
the processor circuitry exhibits a default to display inside-out VR content;
the content detection circuitry is configured to detect presence of outside-in VR content; and
the processor circuitry is further configured to display outside-in VR content responsive to the content detection circuitry detecting the presence of outside-in VR content.

3. The system of claim 1 , wherein the inside-out VR content comprises VR content based on the MICROSOFT® WINDOWS® HOLOGRAPHIC™ platform.

4. The system of claim 1 , wherein the outside-in VR content comprises VR content based on the STEAM® VR platform.

5. The system of claim 1 , further comprising a display device configured to display images corresponding to the VR content to the user.

6. The system of claim 5 , wherein the display device is a stereoscopic display of a head mounted display, the head mounted display having a head piece configured to be worn by a user to position the stereoscopic display.

7. The system of claim 1 , wherein the processor circuitry comprises first processor circuitry, configured to process outside-in VR content, and second processor circuitry configured to process inside-out VR content.

8. The system of claim 7 , wherein the switching circuitry is configured to switch processing between the first processor circuitry and the second processor circuitry.

9. A virtual reality (VR) method for displaying VR content to a user with a head mounted display, the method comprising:
determining a type of VR content provided to a head mounted display from among inside-out VR content and outside-in VR content by determining whether a driver associated with outside-in VR content is active;
displaying the VR content to the user with the head mounted display in accordance with the type of VR content determined such that, if the VR content is determined to be inside-out VR content, the head mounted display displays the inside-out VR content, and if the VR content is determined to be outside-in VR content, the head mounted display displays the outside-in VR content; and
switching from an inside-out VR content mode to an outside-in VR content mode to display the VR content as outside-in VR content responsive to determining that the driver associated with outside-in VR content is active.

10. The method of claim 9 , wherein:
determining the type of VR content comprises detecting a component associated with outside-in VR content; and
the method further comprises switching from an inside-out VR content mode to an outside-in VR content mode responsive to detecting the component associated with outside-in VR content.

11. The method of claim 10 , wherein:
the component is an accessory; and
detecting the component comprises detecting a signal transmitted by the accessory.

12. The method of claim 10 , wherein:
the component is an external sensor remote from the head mounted display; and
detecting the component comprises detecting a signal transmitted by the external sensor.

13. A virtual reality (VR) system for displaying VR content to a user, the system comprising:
a head mounted display having a head piece and a display, the head piece being configured to be worn by a user to position the display, the display being configured to display the VR content to the user;
the head mounted display further comprising a first onboard sensor and a sensor hub, the first onboard sensor having sensor circuitry and being configured to determine movement of the head mounted display, the sensor hub having hub circuitry and being configured to receive movement information corresponding to movement of the head mounted display as detected by a first external sensor remote from the head mounted display;
wherein the head mounted display is configured to selectively display, via the display, inside-out VR content in accordance with the movement of the head mounted display based on the first onboard sensor and outside-in VR content in accordance with the movement of the head mounted display associated with detection by the first external sensor.

14. The system of claim 13 , further comprising the first external sensor.

15. The system of claim 13 , further comprising an accessory configured to transmit a signal to the sensor hub.

16. The system of claim 13 , wherein the head mounted display has a switch configured to enable selective display of outside-in VR content in response to determining presence of outside-in VR content.

17. A virtual reality (VR) method comprising:
providing a head mounted display configured to display VR content to a user; and
selectively displaying inside-out VR content to the user with the head mounted display in accordance with movement of the head mounted display based on a first onboard sensor, and outside-in VR content to the user with the head mounted display in accordance with movement of the head mounted display relative to a first external sensor remotely positioned from the head mounted display.

18. The method of claim 17 , further comprising:
displaying a first object to the user within a VR environment associated with the outside-in VR content, the first object corresponding to a first accessory, the first object being displayed in accordance with movement of the first accessory relative to the first external sensor.
