Method for detecting display screen boundaries

1 . A computer-implemented method for detecting a display screen using an extended reality display device, comprising:

receiving, at the extended reality display device, an image corresponding to a predetermined frame of a video stream, the predetermined frame comprising a plurality of specified feature points;

receiving, at the extended reality display device, data from a game data stream associated with the video stream;

monitoring a display screen that is displaying the video stream;

detecting, using image tracking, at least some of the plurality of specified feature points in the predetermined frame of the video stream as displayed on the display screen; and

determining, based on the data received from the game data stream and a known location of each detected specified feature points relative to at least one physical boundary of the display screen, the physical boundaries of the display screen.

2 . The computer-implemented method of claim 1 , further comprising:

determining, based on the detected specified feature points, an orientation and a location of the display screen.

3 . The computer-implemented method of claim 1 , wherein determining, based on the detected specified feature points, the physical boundaries of the display screen, comprises:

comparing the detected specified feature points to the image corresponding to the predetermined frame of the video stream.

4 . The computer-implemented method of claim 1 , wherein, in response to the extended reality display device failing to detect a sufficient number of the specified feature points to enable the physical boundaries of the display screen to be detected, the method comprises outputting a notification from the extended reality display device.

5 . The computer-implemented method of claim 1 , comprising receiving, at the extended reality display device, a plurality of images, each image corresponding to one of a plurality of predetermined frames of the video stream, each predetermined frame comprising a respective plurality of specified feature points.

6 . The computer-implemented method of claim 5 , wherein in response to the extended reality display device failing to detect a sufficient number of the specified feature points in a first one of the plurality of predetermined frames to enable the physical boundaries of the display screen to be determined, the method comprises receiving a second image corresponding to a second predetermined frame of the video stream.

7 . The computer-implemented method of claim 6 , comprising:

detecting at least some of the plurality of specified feature points in the second predetermined frame of the video stream as displayed on the display screen; and

determining, based on the detected specified feature points of the second predetermined frame, the physical boundaries of the display screen.

8 . The computer-implemented method of claim 1 , wherein in response to the extended reality display device failing to determine the physical boundaries of the display screen, the method comprises:

receiving at the extended reality display device a test image, the test image comprising a plurality of specified feature points;

detecting at least some of the plurality of specified feature points in the test image as displayed on the display screen; and

determining, based on the detected specified feature points in the test image, the physical boundaries of the display screen.

9 . The computer-implemented method of claim 1 , wherein the video stream is a video game or a computer game.

10 . The computer-implemented method of claim 1 , further comprising:

providing the determined physical boundaries of the display screen to one or more electronic devices operably connected to the extended reality display device via a communication network.

11 . The computer-implemented method of claim 1 , wherein the extended reality display device and the display screen are in communication with a plurality of electronic devices via a communication network, the method further comprising:

communicating with the plurality of electronic devices to determine if the physical boundaries of the display screen are known by any of the plurality of electronic devices.

12 . The computer-implemented method of claim 1 , further comprising:

generating one or more virtual boundaries aligned with or overlapping with the determined physical boundaries of the display screen.

13 . The computer-implemented method of claim 12 , wherein:

the one or more virtual boundaries are fixed relative to the respective physical boundaries of the display screen; and/or

the one or more virtual boundaries provide a virtual representation of the physical boundaries of the display screen within a virtual environment created by the extended reality display device.

14 . A device comprising:

a display;

a processor; and

a memory including executable instructions that, as a result of execution by the processor, causes the device to:

receive, at the device, an image corresponding to a predetermined frame of a video stream, the predetermined frame comprising a plurality of specified feature points;

receive, at the device, data from a game data stream associated with the video stream;

monitor the display that is displaying the video stream;

detect, using image tracking, at least some of the plurality of specified feature points in the predetermined frame of the video stream as displayed on the display; and

determine, based on the data received from the game data stream and a known location of each detected specified feature points relative to at least one physical boundary of the display, the physical boundaries of the display.

15 . The device of claim 14 , wherein the device is an augmented reality, AR, headset.

16 . A system comprising:

a display screen;

a computing device; and

an extended reality display device, wherein the display screen, the computing device and the extended reality display device are operably connected by a communication network, and wherein the extended reality display device comprises:

a processor; and

a memory including executable instructions that, as a result of execution by the processor, causes the extended reality display device:

receive, at the extended reality display device, an image corresponding to a predetermined frame of a video stream, the predetermined frame comprising a plurality of specified feature points;

receive, at the extended reality display device, data from a game data stream associated with the video stream;

monitor a display screen that is displaying the video stream;

detect, using image tracking, at least some of the plurality of specified feature points in the predetermined frame of the video stream as displayed on the display screen; and

determine, based on the data received from the game data stream and a known location of each detected specified feature points relative to at least one physical boundary of the display screen, the physical boundaries of the display screen.
