Adjusting content of a head mounted display
Apparatuses, methods, systems, and program products are disclosed for adjusting content of a head mounted display. An apparatus includes a processor and a memory that stores code executable by the processor to determine a field of view for a user relative to a display of a head-mounted display unit, detect that the user is attempting to look at content that is presented on the display of the head-mounted display unit but is out of the user's field of view, and adjust the content that is out of the user's field of view to make the content visible to the user.
1. An apparatus comprising:
a processor; and
a memory that stores code executable by the processor to:
determine a field of view for a user relative to a display of a head-mounted display (HMD) unit, the field of view including first virtual content being displayed on the display;
detect that the user is attempting to look at second virtual content, wherein the second virtual content is outside the user's field of view and is not currently visible to the user; and
while maintaining the user's field of view and responsive to a change in the user's gaze, move the second virtual content that is outside the user's field of view and not visible to the user to within the user's field of view and visible to the user by moving the second virtual content that is outside the user's field of view from its current location outside the user's field of view and not visible to the user to within the user's field of view and visible to the user to allow the user to simultaneously view the first virtual content and the second virtual content in the user's field of view,
wherein the second virtual content that is moved to within the user's field of view does not block the first virtual content that is of interest to the user being displayed on the display within the user's field of view.
2. The apparatus of claim 1 , wherein the code is executable by the processor to detect that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user by detecting eye movement within an eye-box defined for the HMD unit directed towards the second virtual content.
3. The apparatus of claim 2 , wherein the code is executable by the processor to detect the eye movement within the eye-box based on input from a camera mounted on the HMD unit and pointed towards the user's eyes.
4. The apparatus of claim 2 , wherein the code is executable by the processor to detect the eye movement within the eye-box based on input from a distance sensor mounted on the HMD unit and pointed towards the user's eyes.
5. The apparatus of claim 2 , wherein the code is executable by the processor to detect the eye movement within the eye-box in response to detecting that the user is manually adjusting a position of the HMD unit on the user's head.
6. The apparatus of claim 1 , wherein the code is executable by the processor to detect that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user by detecting that the user is looking in a direction of the second virtual content and detecting that the user is moving the HMD unit in a same direction.
7. The apparatus of claim 1 , wherein moving the second virtual content further comprises resizing the second virtual content to be one of larger and smaller to avoid the second virtual content from overlapping with the first virtual content displayed on the display.
8. The apparatus of claim 1 , wherein the second virtual content that is outside the user's field of view and not visible to the user comprises tag-along content.
9. The apparatus of claim 1 , wherein the code is further executable by the processor to trigger re-calibrating the user's field of view relative to the display of the HMD unit in response to detecting that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user.
10. A method comprising:
determining, by a processor, a field of view for a user relative to a display of a head-mounted display (HMD) unit, the field of view including first virtual content being displayed on the display;
detecting that the user is attempting to look at second virtual content, wherein the second virtual content is outside the user's field of view and is not currently visible to the user; and
while maintaining the user's field of view and responsive to a change in the user's gaze, moving the second virtual content that is outside the user's field of view and not visible to the user to within the user's field of view and visible to the user by moving the second virtual content from its current location outside the user's field of view and not visible to the user to within the user's field of view and visible to the user to allow the user to simultaneously view the first virtual content and the second virtual content in the user's field of view,
wherein the second virtual content that is moved to within the user's field of view does not block the first virtual content that is of interest to the user being displayed on the display within the user's field of view.
11. The method of claim 10 , wherein detecting that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user comprises detecting eye movement within an eye-box defined for the HMD unit directed towards the second virtual content.
12. The method of claim 11 , further comprising detecting the eye movement within the eye-box based on input from a camera mounted on the HMD unit and pointed towards the user's eyes.
13. The method of claim 11 , further comprising detecting the eye movement within the eye-box based on input from a distance sensor mounted on the HMD unit and pointed towards the user's eyes.
14. The method of claim 11 , further comprising detecting the eye movement within the eye-box in response to detecting that the user is manually adjusting a position of the HMD unit on the user's head.
15. The method of claim 10 , wherein moving the second virtual content further comprises resizing the second virtual content to be one of larger and smaller to avoid the second virtual content from overlapping with content displayed on the display.
16. A program product comprising a non-transitory computer-readable storage medium that stores code executable by a processor, the executable code comprising code to:
determine a field of view for a user relative to a display of a head-mounted display (HMD) unit, the field of view including first virtual content being displayed on the display;
detect that the user is attempting to look at second virtual content, wherein the second virtual content is outside the user's field of view and is not currently visible to the user; and
while maintaining the user's field of view and responsive to a change in the user's gaze, move the second virtual content that is outside the user's field of view and not visible to the user to within the user's field of view and visible to the user by moving the second virtual content from its current location outside the user's field of view and not visible to the user to within the user's field of view and visible to the user to allow the user to simultaneously view the first virtual content and the second virtual content in the user's field of view,
wherein the second virtual content that is moved to within the user's field of view does not block the first virtual content that is of interest to the user being displayed on the display within the user's field of view.
17. The program product of claim 16 , wherein the executable code further comprises code to detect that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user by detecting eye movement within an eye-box defined for the HMD unit directed towards the second virtual content.
18. The program product of claim 16 , wherein the executable code further comprises code to detect that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user by detecting that the user is looking in a direction of the second virtual content and detecting that the user is moving the HMD unit in a same direction.
19. The program product of claim 16 , wherein moving the second virtual content further comprises resizing the second virtual content to be one of larger and smaller to avoid the second virtual content from overlapping with the first virtual content displayed on the display.
20. The program product of claim 16 , wherein the executable code further comprises code to trigger re-calibrating the user's field of view relative to the display of the HMD unit in response to detecting that the user is attempting to look at the second virtual content that is outside the user's field of view and not visible to the user.
