Abstract

A system for linking and controlling terminals is disclosed. A user terminal includes an image unit configured to output image data corresponding to a first image to be shared with a receiving terminal viewed by a user of the user terminal, and a signal unit configured to transmit the image data outputted from the image unit and position information of a touch means touching the user terminal to the receiving terminal. Here, the position information is position information of the touch means touching the user terminal at a preset pressure level or lower or with a preset contact area or smaller, and is displayed on the receiving terminal in an image form.

Claims

1. A user terminal used in a terminal linkage system, the user terminal comprising:

an image unit configured to output image data corresponding to a first image to be shared with a receiving terminal viewed by a user of the user terminal, the receiving terminal having a size larger than the user terminal; and

a signal unit configured to transmit the image data outputted from the image unit and position information of a touch means touching the user terminal to the receiving terminal,

wherein the position information is position information of the touch means touching the user terminal at a preset pressure level or lower or with a preset contact area or smaller, and is displayed on the receiving terminal in an image form.

2. The user terminal of claim 1, wherein at least one of a shape, size, and color of a second image displayed on the receiving terminal according to the transmitted position information is varied depending on a touch strength of the touch means on the user terminal.

3. The user terminal of claim 1, further comprising:

a linkage unit configured to manage a linkage between the user terminal and the receiving terminal; and

a settings unit configured to manage settings related to the linkage,

wherein the settings unit changes at least one setting while the user terminal and the receiving terminal are in a linked state.

4. The user terminal of claim 1, wherein the user terminal further comprises a touch means unit, and the user terminal has a receiver installed thereon,

wherein the receiver senses ultrasonic waves and infrared rays emitted from the touch means to detect a position of the touch means, and the signal unit controls the receiver to transmit the position information to the receiving terminal.

5. The user terminal of claim 1, further comprising:

a display unit configured to display the first image corresponding to the image data outputted from the image unit;

an electromagnetic field generator attached to a rear surface of the display unit and configured to generate an electromagnetic field; and

a sensing unit,

and wherein the touch means has a metal coil wound around an end thereof, electromagnetic induction occurs in the metal coil due to the generated electromagnetic field, the electromagnetic field is altered due to the electromagnetic induction, and the sensing unit detects a position of the touch means by sensing the altered electromagnetic field.

6. A user terminal used in a terminal linkage system, the user terminal comprising:

an image unit configured to output image data, the image data including a first image to be shared with a receiving terminal viewed by a user of the user terminal and a second image indicating a position of a touch means when the touch means touches the user terminal and the receiving terminal having a size larger than the user terminal; and

a signal unit configured to transmit to the receiving terminal the image data outputted from the image unit,

wherein the position of the touch means is a position of the touch means touching the user terminal at a preset pressure level or lower or with a preset contact area or smaller, and the first image and the second image are displayed on the receiving terminal.

7. The user terminal of claim 6, further comprising:

a sensing unit configured to sense a touch of the touch means.

8. The user terminal of claim 6, wherein at least one of a shape, size, and color of the second image displayed on the receiving terminal according to the transmitted image data is varied depending on a touch strength of the touch means on the user terminal.

9. The user terminal of claim 6, further comprising:

a linkage unit configured to manage a linkage between the user terminal and the receiving terminal; and

a settings unit configured to manage settings related to the linkage,

wherein the settings unit changes at least one setting while the user terminal and the receiving terminal are in a linked state.

10. A user terminal used in a terminal linkage system, the user terminal comprising:

a display unit; and

a signal unit configured to transmit image information and position information of a touch means touching the user terminal to a receiving terminal having a size larger than the user terminal and viewed by a user of the user terminal,

wherein the position information is position information of the touch means touching the user terminal at a preset pressure level or lower or with a preset contact area or smaller, and is displayed on the receiving terminal in an image form.

11. The user terminal of claim 10, further comprising:

a sensing unit configured to sense a touch of the touch means.

12. A user terminal used in a terminal linkage system, the user terminal comprising:

a display unit; and

a signal unit configured to transmit combined image data to a receiving terminal having a size larger than the user terminal and viewed by a user of the user terminal,

wherein the combined image data includes first image data and second image data, the second image data relating to a position of a touch means touching the user terminal, the position of the touch means is a position of the touch means touching the user terminal at a preset pressure level or lower or with a preset contact area or smaller, and a first image corresponding to the first image data and a second image corresponding to the second image data are displayed on the receiving terminal.

13. The user terminal of claim 12, further comprising:

a sensing unit configured to sense a touch of the touch means.
