Abstract

Various arrangements for defining a marker are presented. A first defined marker presented by a public display device may be determined to be insufficient for use by a head mounted display. The first defined marker may be used as a reference point for positioning information for display by the head mounted display. In response to determining that the first defined marker is insufficient, a second marker displayed by the public display device may be defined. The second marker may have a display characteristic different from the first defined marker. The second defined marker may then be used as the reference point for positioning the information for display by the head mounted display. An indication of the second marker may be transmitted to the head mounted display.

First claim

What is claimed is:

1. A method for defining a marker, the method comprising:
determining, by a display control system, that a first defined marker presented by a public display device separate from and communicatively coupled to the display control system is insufficient for use by a head mounted display separate from and communicatively coupled to the display control system, wherein
the first defined marker is used as a reference point for positioning information for display by the head mounted display;

in response to determining that the first defined marker is insufficient, defining, by the display control system, a second marker displayed by the public display device, the second marker being at a different location than the first defined marker, wherein
the second defined marker is used as the reference point for positioning the information for display by the head mounted display; and

transmitting, by the display control system, an indication of the second marker to the head mounted display enabling the head mounted display to locate the second marker.

2. The method for defining the marker of claim 1 , wherein determining that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises:
receiving, by the display control system, feedback from the head mounted display, that indicates the first defined marker cannot be located.

3. The method for defining the marker of claim 1 , wherein determining that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises:
receiving, by the display control system, distance data indicating a distance between the public display device and the head mounted display; and
determining, by the display control system, that the first defined marker is insufficient based at least on the distance between the public display device and the head mounted display.

4. The method for defining the marker of claim 1 , wherein determining that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises:
measuring, by the display control system, an amount of ambient lighting in a vicinity of the public display device; and
determining, by the display control system, that the first defined marker is insufficient based at least on the amount of ambient lighting.

5. The method for defining the marker of claim 1 , wherein determining the indication that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises:
calculating, by the head mounted display, a distance between the head mounted display and the public display device; and
transmitting, by the head mounted display, an indication of the distance to the display control system.

6. The method for defining the marker of claim 1 , wherein:
the second defined marker is larger in size than the first defined marker.

7. The method for defining the marker of claim 1 , further comprising:
defining, by the display control system, a third marker displayed by the public display device concurrently with the second marker, the third marker having a display characteristic different from display characteristics of the second defined marker, wherein
the third defined marker is used as the reference point for positioning information for display by a second head mounted display; and

transmitting, by the display control system, the third marker to the second head mounted display.

8. The method for defining the marker of claim 7 , wherein the third defined marker and the second defined marker are presented simultaneously as part of public information presented by the public display device.

9. The method for defining the marker of claim 1 , wherein the second defined marker is a dedicated marker presented by the public display device.

10. The method for defining the marker of claim 1 , wherein the display control system determines information to be displayed on the public display device and the head mounted display.

11. The method of claim 1 , wherein determining the first defined marker presented by the public display device is insufficient for use by the head mounted display is performed by the display control system automatically without user input.

12. A system for defining a marker, the system comprising:
one or more processors; and
a memory communicatively coupled with and readable by the one or more processors and having stored therein processor-readable instructions which, when executed by the one or more processors, cause the one or more processors to:
determine that a first defined marker presented by a public display device separate from and communicatively coupled to the system is insufficient for use by a head mounted display separate from and communicatively coupled to the system, wherein
the first defined marker is used as a reference point for positioning information for display by the head mounted display;

in response to determining that the first defined marker is insufficient, define a second marker displayed by the public display device, the second marker being at a different location than the first defined marker, wherein
the second defined marker is used as the reference point for positioning the information for display by the head mounted display; and

transmit an indication of the second marker to the head mounted display enabling the head mounted display to locate the second marker.

13. The system for defining the marker of claim 12 , wherein the processor-readable instructions that cause the one or more processors to determine that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises processor-readable instructions which, when executed, cause the one or more processors to:
receive feedback from the head mounted display, that indicates the first defined marker cannot be located.

14. The system for defining the marker of claim 12 , wherein the processor-readable instructions that cause the one or more processors to determine that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises processor-readable instructions which, when executed, cause the one or more processors to:
receive distance data indicating a distance between the public display device and the head mounted display; and
determine that the first defined marker is insufficient based at least on the distance between the public display device and the head mounted display.

15. The system for defining the marker of claim 12 , wherein the processor-readable instructions that cause the one or more processors to determine that the first defined marker presented by the public display device is insufficient for use by the head mounted display comprises processor-readable instructions which, when executed, cause the one or more processors to:
measure an amount of ambient lighting in a vicinity of the public display device; and
determine that the first defined marker is insufficient based at least on the amount of ambient lighting.

16. The system for defining the marker of claim 12 , further comprising:
the head mounted display, configured to:
calculate a distance between the head mounted display and the public display device; and
transmit an indication of the distance to the display control system.

17. The system for defining the marker of claim 12 , wherein the second defined marker is larger in size tha
