Abstract

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.

Claims

1. A head-mounted device that is worn on a user'"'"'s head and configured to integrate with a removable portable electronic device, comprising:

a frame comprising a cavity that is configured to physically receive and carry the removable portable electronic device, wherein the frame places a display screen of the portable electronic device in front of the user'"'"'s eyes, and wherein the display screen of the portable electronic device acts as the primary display screen of the head-mounted device such that the display screen of the portable electronic device is primarily used to view image based content when the head-mounted display device is worn on the user'"'"'s head;

a detection mechanism configured to alter the portable electronic device based on whether the removable portable electronic device is mounted on the frame; and

an optical subassembly operative to;

receive at least one image frame from the display screen of the portable electronic device, wherein the at least one image frame comprises the image based content; and

adjust the image based content based at least in part on relative sizes of the display and the display screen of the portable electronic device.

2. The device of claim 1 further comprising:

a connector that is operative to couple with a corresponding connector of the portable electronic device, wherein the coupled connectors allows communication between the head-mounted device and the portable electronic device.

3. The device of claim 1 further comprising:

one or more input devices for receiving inputs.

4. The device of claim 1 further comprising:

one or more output devices for providing feedback associated with content being outputted by the portable electronic device.

5. The device of claim 1, wherein the frame includes a docking area for placement of the portable electronic device, wherein the docking area includes an opening that provides viewing access to the display screen of the portable electronic device.

6. The device of claim 1 wherein the portable electronic device creates an image frame of the at least one image frame that is smaller than the size of the screen when it is carried by the frame.

7. The device of claim 1 wherein the frame defines a cavity into which the portable electronic device is inserted.

8. The device of claim 1 further comprising one clip operative to help retain the portable electronic device to the frame.

9. The device of claim 1, wherein the optical subassembly is operative to adjust a resolution of the at least one image frame to compensate for how close the user'"'"'s eyes are to the display screen of the portable electronic device.

10. The device of claim 1, wherein the optical subassembly is operative to enhance viewing effects of the image based content.

11. The device of claim 10, wherein the optical subassembly is operative to:

detect that the display of the head-mounted device is larger than the at least one image frame; and

use at least one portion of the display surrounding the at least one image frame to produce a secondary effect.

12. The device of claim 11, wherein the secondary effect comprises colors associated with at least one of an edge of the at least one image frame and a corner of the at least one image frame.
