Abstract

A head mountable display (HMD) is operable to detect the HMD'"'"'s overall motion relative to its current orientation, and to display extra image material so that the extra image material moves in the same general direction as real objects would be seen by the user to move if the user were not wearing the HMD.

Claims

1. A head mountable display (HMD) comprising:

a motion detector configured to detect an overall motion of the HMD relative to a current orientation of the HMD, and

a display generator configured to generate for display extra image material so that the extra image material moves in a same general direction as real objects would be seen by a user to move if the user were not wearing the HMD;

in which the HMD is configured to display a virtual video screen to the user, and the display generator is configured to generate the extra image material about at least part of a periphery of the virtual video screen.

2. An HMD according to claim 1, in which the extra image material comprises discrete objects.

3. An HMD according to claim 2, in which the discrete objects are light objects on a dark background.

4. An HMD according to claim 1, in which the extra image material comprises an image pattern.

5. An HMD according to claim 1, comprising a camera mounted with respect to the HMD, the HMD being configured to detect the overall motion of the HMD relative to the current orientation of the HMD by image analysis of images captured by the camera.

6. An HMD according to claim 1, comprising a global positioning system (GPS) detector.

7. An HMD according to claim 1, wherein the HMD is configured to acquire position data from a position detector associated with a moving vehicle in which the HMD is situated.

8. An HMD according to claim 6, in which the extra image material comprises map data or image data relating to a physical location of the HMD.

9. An HMD according to claim 1, in which the HMD is configured to display received image material having associated metadata defining the extra image material.

10. A system, comprising:

a head mountable display (HMD) comprising;

a motion detector configured to detect an overall motion of the HMD relative to a current orientation of the HMD, and

a display generator configured to generate for display extra image material so that the extra image material moves in a same general direction as real objects would be seen by a user to move if the user were not wearing the HMD;

in which the HMD is configured to display a virtual video screen to the user, and the display generator is configured to generate the extra image material about at least part of a periphery of the virtual video screen; and

one or more of a base device and an intermediate device coupled to the HMD.

11. A method of operation of a head mountable display (HMD), the method comprising:

displaying a virtual video screen to an HMD user;

detecting overall motion of the HMD relative to a current orientation of the HMD; and

displaying extra image material about at least part of a periphery of the virtual video screen so that the extra image material moves in a same general direction as real objects would be seen by the HMD user to move if the HMD user were not wearing the HMD.

12. A non-transitory machine-readable storage medium which stores computer software which, when executed by a computer, causes the computer to carry out the method of claim 11.
