Abstract

The purpose of the invention is a method for activating a mobile device in a network comprising at least one display device being coupled to a sensor. This method is characterised by the fact that it comprises: detecting the mobile device via the sensor coupled to the display device; displaying a device representative of the detected mobile device, called a virtual device, on the display device such that the position of the virtual device on the display screen is linked to the position of the mobile device in the capture field of the sensor; activating the mobile device in the network when a determined action is applied by the user to the mobile device. Another purpose of the invention is a display device and a system implementing the method.

First claim

The invention claimed is:

1. A method implemented in a display device, the method comprising:
obtaining a first image of a physical mobile device via a camera coupled to the display device in a network;
recognizing the physical mobile device based on the first image of the physical mobile device,
wherein a detection of a wireless proximity with the physical mobile device activates the camera to obtain the first image and initiates a process to recognize the physical mobile device based on the first image;
displaying a second image comprising a representation of the physical mobile device at a first position in the second image, such that the first position of the representation of the physical mobile device in the displayed second image is linked to a position of the physical mobile device in a capture field of the camera,
wherein the representation of the physical mobile device moves in the displayed second image according to a displacement of the physical mobile device; and
responsive to detecting movement of the representation of the physical mobile device from the first position to an area of the displayed second image designated for activation,
activating the physical mobile device in the network.

2. The method of claim 1 , wherein the process to recognize the physical mobile device comprises an image processing of the first image.

3. The method of claim 1 , wherein the camera is activated from a standby state by the detection of the wireless proximity with the physical mobile device.

4. The method of claim 1 ,
wherein a shape is associated with the physical mobile device, and
wherein the process to recognize the physical mobile device comprises an object recognition from shapes.

5. The method of claim 4 , wherein the representation of the physical mobile device is based on the shape.

6. The method of claim 1 , further comprising removing the physical mobile device from the network responsive to detecting second movement of the representation of the physical mobile device away from the area of the displayed second image designated for activation or to a second area of the displayed second image designated for deactivation.

7. The method of claim 1 , wherein the first image of the physical mobile device is a front face image of the physical mobile device.

8. The method of claim 7 ,
wherein the process to recognize the physical mobile device uses a signature of the front face image of the physical mobile device, and
wherein the signature is based on visual characteristics distinguishing different physical mobile devices.

9. A display device comprising a processor and a display screen, wherein the processor is configured to:
obtain a first image of a physical mobile device from a camera coupled to the display device in a network; and
recognize the physical mobile device based on the first image of the physical mobile device,
wherein a detection of a wireless proximity with the physical mobile device is configured to activate the camera to obtain the first image and to initiate a process to recognize the physical mobile device based on the first image,
wherein the display screen is configured to display a second image comprising a representation of the physical mobile device at a first position in the second image, such that the first position of the representation of the physical mobile device in the displayed second image is linked to a position of the physical mobile device in a capture field of the camera,
wherein the representation of the physical mobile device moves in the displayed second image according to a displacement of the physical mobile device, and
wherein the processor is further configured to activate the physical mobile device in the network responsive to detecting movement of the representation of the physical mobile device from the first position to an area of the displayed second image designated for activation.

10. The display device of claim 9 , wherein the process to recognize the physical mobile device comprises an image processing of the first image.

11. The display device of claim 9 , wherein the camera is activated from a standby state by the detection of the wireless proximity with the physical mobile device.

12. The display device of claim 9 ,
wherein a shape is associated with the physical mobile device, and
wherein the process to recognize the physical mobile device comprises an object recognition from shapes.

13. The display device of claim 12 , wherein the representation of the physical mobile device is based on the shape.

14. The display device of claim 9 , wherein the processor is further configured to remove the physical mobile device from the network responsive to detecting second movement of the representation of the physical mobile device away from the area of the displayed second image designated for activation or to a second area of the displayed second image designated for deactivation.

15. The display device of claim 9 , wherein the first image of the physical mobile device is a front face image of the physical mobile device.

16. The display device of claim 15 ,
wherein the process to recognize the physical mobile device uses a signature of the front face image of the physical mobile device, and
wherein the signature is based on visual characteristics distinguishing different physical mobile devices.

17. The display device of claim 9 , wherein the display device further comprises the camera.
