Method and system for managing the interaction of multiple displays

1. A method for managing an interaction of screens in at least two devices, which, when combined, expand a display area in different alignments and orientations, the method comprising:

detecting, by the at least two devices, a contact between the at least two devices;

automatically selecting which device of the at least two devices will be designated as a primary device such that the primary device and a secondary device are designated, based on at least one of a processing power, a screen dimension, a screen proportion, a screen resolution, and a predefined user preference of each of the at least two devices;

receiving, by the at least two devices, the designation of the primary device and the secondary device;

exchanging, by the at least two devices, messages with each other containing information regarding the contact between the at least two devices specifying the contact side of each device and the screen orientation of each device;

updating an image on a screen of the primary device to display a partial area of the image in an orientation aligned with the image prior to the detecting the contact between the at least two devices, based on the exchanged information; and

updating an image on a screen of the secondary device to display a partial area of the image also in the orientation aligned with the image prior to the detecting the contact between the at least two devices, based on the exchanged information,

wherein the screen of the primary device and the screen of the secondary device together display and rotate the images as a compound image on a compound screen.

2. The method of claim 1 , wherein the at least two devices include at least one of:

at least two independent devices each including a screen; and

at least one device with a built-in primary screen and a detachable secondary screen.

3. The method of claim 1 , wherein the at least two devices have at least one of different physical dimensions and image resolutions, or have at least one of the same physical dimensions and image resolutions.

4. The method of claim 1 , wherein the contact is detected using sensors positioned on the sides of each of the at least two devices, wherein the sensors are responsible for identifying which side among a left, right, top, and bottom side of the primary device has contacted which side among a left, right, top, and bottom side of the secondary device.

5. The method of claim 1 , wherein, based on an orientation of the primary device and the detected contact between the primary device and the secondary device, the exchanged information includes:

which portion of the image will be displayed by the screen on the primary device;

which portion of the image will be displayed by the screen on the secondary device; and

orientation of the screen on the secondary device.

6. A device to expand a display area in different alignments and orientations, the device comprising:

a processor;

a detector configured to detect a contact between at least two devices including the device and a secondary device;

a selector configured to automatically select, by the processor, which device of the at least two devices will be designated as a primary device such that the primary device and the secondary device are designated, based on at least one of a processing power, a screen dimension, a screen proportion, a screen resolution, and a predefined user preference of each of the at least two devices;

a receiver configured to receive the designation of the primary device and the secondary device;

an exchanger configured to exchange messages with the secondary device containing information regarding the contact between the at least two devices specifying the contact side of each device and the screen orientation of each device; and

an updater configured to update an image on a screen of the primary device to display a partial area of the image in an orientation aligned with the image prior to the detecting the contact between the at least two devices, based on the exchanged information,

wherein the information exchanged with the secondary device allows the secondary device to update an image on a screen of the secondary device to display a partial area of the image also in the orientation aligned with the image prior to the detecting the contact between the at least two devices, based on the exchanged information, and

wherein the screen of the primary device and the screen of the secondary device together display and rotate the images as a compound image on a compound screen.

7. The device of claim 6 , further comprising at least one sensor including at least one of mechanical, electromagnetic, accelerometer, Near Field Communication (NFC), and Wireless Gigabit Alliance (WiGig) Communication.

8. The device of claim 6 , wherein the detector detects the contact by at least one of Near Field Communication (NFC), Wireless Local Area Network (WLAN), Wireless Gigabit Alliance (WiGig) Communication, and accelerometers.

9. The device of claim 6 , wherein the at least devices include:

at least two independent devices; and

at least one device with a built-in primary screen and a detachable secondary screen.

10. A non-transitory computer-readable recording medium storing a program to implement the method of claim 1 .
