Abstract

A personal display system with which a user may adjust the configuration of displayed media is provided. The personal display system may include an electronic device operative to provide media to a personal display device operative to display the received media. Using one or more optical and digital components, the personal display device may adjust displayed media to overlay features of a theater, thus giving the user of the personal display device the impression of being in the theater. In some embodiments, the personal display device may detect the user'"'"'s movements using one or more sensors and may adjust the displayed image based on the user'"'"'s movements. For example, the device may detect a user'"'"'s head movement and cause the portion of media displayed to reflect the head movement.

Claims

1. A method for automatically adjusting a portion of media displayed to a user of a personal display device, comprising:

displaying media using the personal display device, wherein the portion of media displayed by the personal display device is less than the available media;

detecting a movement of the user'"'"'s head;

defining a rate and distance by which to displace the displayed portion of the media;

waiting to displace the portion of the media displayed for a period of time; and

after the period of time has passed, displacing the portion of the media displayed in response to the detected movement of the user'"'"'s head using the defined rate and distance.

2. The method of claim 1, wherein detecting a movement of the user'"'"'s head further comprises detecting a movement of the user'"'"'s head using at least one sensor incorporated in the personal display device.

3. The method of claim 2, wherein the sensor comprises at least one of an accelerometer, a position sensor, a gyroscope, a distance sensor, a biological sensor, a geodetic sensor, an optical sensor, a video sensor, and a RF sensor.

4. The method of claim 2, wherein defining the rate further comprises:

defining at least one vector based on the output of the at least one sensor; and

defining the rate of displacement of the displayed portion of the media based on the at least one defined vector.

5. The method of claim 1, wherein displacing the portion of the media displayed further comprises linearly displacing the portion of the media displayed based on the detected movement of the user'"'"'s head.

6. The method of claim 1, further comprising determining whether the periphery of the portion of media displayed in the display of the personal display device is less than the periphery of the available media.

7. The method of claim 1, further comprising:

determining whether the detected movement of the user'"'"'s head exceeds a defined floor; and

in response to determining that the detected movement of the user'"'"'s head does not exceed the defined floor, ignoring the detected movement of the user'"'"'s head.

8. The method of claim 1, further comprising:

determining whether to detect movements of the user'"'"'s head; and

in response to determining to detect movements of the user'"'"'s head, detecting movements of the user'"'"'s head.

9. The method of claim 8, wherein determining whether to detect movements of the user'"'"'s head further comprises determining whether the user provided an instruction to detect movements of the user'"'"'s head.

10. The method of claim 1, wherein detecting a movement of the user'"'"'s head further comprises detecting information comprising at least one of a direction, speed, amount, and rate of the movement of the user'"'"'s head using at least one sensor.

11. The method of claim 10, further comprising converting the detected information into at least one structure defining the movement of the user'"'"'s head for processing.

12. The method of claim 11, wherein the at least one structure comprises at least one vector quantity.

13. The method of claim 11, wherein at least one of the rate and the distance by which to displace the displayed portion of the media is directly proportional with the at least one structure.

14. The method of claim 11, wherein the rate by which to displace the displayed portion of the media is constant, and the distance by which to displace the displayed portion of the media is based on the at least one structure.

15. The method of claim 11, wherein the rate by which to displace the displayed portion of the media is based at least in part on the at least one structure, and the distance by which to displace the displayed portion of the media is independent of the at least one structure.

16. A method for automatically adjusting a portion of media displayed to a user of a personal display device, comprising:

displaying media using the personal display device, wherein the portion of media displayed by the personal display device is less than the available media;

detecting a movement of the user'"'"'s head;

defining a rate and distance by which to displace the displayed portion of the media based on the detected movement of the user'"'"'s head;

waiting to displace the portion of the media displayed for a period of time; and

after the period of time has passed, displacing the portion of the media displayed using the defined rate and distance.

17. A method for automatically adjusting a portion of media displayed to a user of a personal display device, comprising:

displaying media using the personal display device, wherein the portion of media displayed by the personal display device is less than the available media;

detecting a movement of the user'"'"'s head;

defining a rate and distance by which to displace the displayed portion of the media, wherein defining the rate and the distance further comprises;

defining at least one vector based on the output of at least one sensor used to detect the movement of the user'"'"'s head; and

defining a rate of displacement of the displayed portion of the media based on the at least one defined vector;

waiting to displace the portion of the media displayed for a period of time; and

after the period of time has passed, displacing the portion of the media displayed based on the defined rate of displacement.
