Head-mounted display apparatus for retaining a portable electronic device with display
Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.
1. A cellular telephone comprising:
a speaker;
a button;
a camera; and
a display, wherein the display is configured to operate in one of a normal viewing mode and a close up viewing mode, wherein the display is configured to operate in the close up viewing mode when the cellular telephone is connected to a head-mounted device, and wherein the display is configured to operate in the normal viewing mode when the cellular telephone is not connected to the head-mounted device.
2. The cellular telephone defined in claim 1 , wherein the display is configured to divide an image frame into a left image frame and a right image frame while operating in the close up viewing mode.
3. The cellular telephone defined in claim 1 , wherein the cellular telephone is configured to be connected to the head-mounted device using a connector.
4. The cellular telephone defined in claim 3 , wherein the connector is configured to couple to a complementary connector in the head-mounted device.
5. The cellular telephone defined in claim 4 , wherein the connector in the cellular telephone is a female connector and the complementary connector in the head-mounted device is a male connector.
6. A portable electronic device that is configured to connect to a head-mounted device, the portable electronic device comprising:
a speaker;
a button;
a camera; and
a display, wherein the display is configured to operate in one of a first display mode and a second display mode, wherein the display presents images in a first format in the first display mode, wherein the display presents images in a second format that is different from the first format in the second display mode, wherein the display is configured to present a left image frame and a right image frame while operating in the second display mode, and wherein the display is configured to operate in the second display mode in response to the portable electronic device being connected to the head-mounted device.
7. The portable electronic device defined in claim 6 , wherein the first display mode is a normal display mode, and wherein the second display mode is a close up display mode.
8. The portable electronic device defined in claim 6 , wherein the display operates in the first display mode when it is detected that the portable electronic device is being used for normal viewing.
9. The portable electronic device defined in claim 8 , wherein the display operates in the second display mode when it is detected that the portable electronic device is being used for close up viewing.
10. The portable electronic device defined in claim 6 , wherein the display is configured to operate in the first display mode when it is detected that the portable electronic device is not connected to the head-mounted device.
11. A method of operating a cellular telephone that is configured to be coupled to a head-mounted device, the method comprising:
presenting images according to a first format in a normal viewing mode while the cellular telephone is not coupled to the head-mounted device;
detecting that the cellular telephone is coupled to the head-mounted device; and
in response to detecting that the cellular telephone is coupled to the head-mounted device, presenting images according to a second format that is different than the first format.
12. The method defined in claim 11 , wherein presenting images according to the first format comprises presenting images with a first resolution.
13. The method defined in claim 12 , wherein presenting images according to the second format comprises presenting images with a second resolution that is different than the first resolution.
14. The method defined in claim 11 , wherein presenting images according to the second format comprises receiving an image frame and dividing the image frame into a first image frame and a second image frame.
15. The method defined in claim 14 , wherein presenting images according to the second format comprises presenting images according to the second format using a display in the cellular telephone.
16. The method defined in claim 15 , wherein presenting images according to the second format using the display comprises directing the first image frame to a first portion of the display and directing the second image frame to a second portion of the display.
17. The method defined in claim 16 , wherein the first image frame is a left image frame and wherein the second image frame is a right image frame.
18. The method defined in claim 17 , wherein the first portion of the display comprises a left portion of the display, and wherein the second portion of the display comprises a right portion of the display.
19. The method defined in claim 11 , wherein presenting images according to the second format comprises presenting images according to the second format in a close up viewing mode.
20. The method defined in claim 11 , wherein detecting that the cellular telephone is coupled to the head-mounted device comprises detecting a wired connection between the head-mounted device and the cellular telephone.
