Abstract

A mobile terminal, an electronic device and a method of controlling the same are provided. The electronic device can be controlled easily and intuitively by using the mobile terminal including a touch device.

First claim

What is claimed is:

1. A mobile terminal capable of communicating with an electronic device including a display, comprising:
a touch device;
a communication unit configured to communicate with the electronic device;
a sensing unit configured to sense an orientation of the touch device, wherein the orientation of the touch device is determined based on a rotation of the touch device on an axis perpendicular to a surface of the touch device; and
a controller configured to:
perform a first matching function where the controller matches a display area of the display included in the electronic device and a touch area of the touch device included in the mobile terminal to each other based on the absolute coordinate system;
when a first point is touched at the touch area of the touch device included in the mobile terminal, generate control information including position information about a second point of the display area of the display included in the electronic device corresponding to the first point and intensity information of the touch at the first point;
transmit the control information to the electronic device through the communication unit;
detect the rotation of the touch device to be disposed in a landscape direction or a portrait direction and perform a second matching function where the controller:
in response to detecting that the touch device is disposed in the portrait direction and the touch at the first point, generates the control information including the position information and matches a width side and a length side of the display area of the display with a length side and a width side of the touch area of the touch device, respectively, and
in response to detecting that the touch device is disposed in the landscape direction and the touch at the first point, generates the control information including the position information and matches the width side and the length side of the display area of the display with the width side and the length side of the touch area of the touch device, respectively; and

control the electronic device to perform different functions according to the intensity information of the touch of the first point,
wherein the control information including the position information about the second point of the display area of the display included in the electronic device generated for the touch at the first point indicates a first location on the display area when the touch device is disposed in the portrait direction and indicates a second location on the display area when the touch device is disposed in the landscape direction, and
wherein the first location is different from the second location and both the first location and the second location correspond to the touch at the first point at the touch area of the touch device.

2. The mobile terminal of claim 1 , wherein the sensing unit includes at least one of an acceleration sensor for sensing the rotation of the touch device on the axis perpendicular to the surface of the touch device and a grab sensor arranged around the touch device to sense an external object's touch point on a body of the mobile terminal.

3. The mobile terminal of claim 2 , wherein the controller uses one of the acceleration sensor and the grab sensor as a main sensor and uses the other as an auxiliary sensor to sense the orientation variation when the sensing unit includes both the acceleration sensor and the grab sensor.

4. The mobile terminal of claim 1 , wherein the controller matches the display area and the touch area to each other based on a resolution of the display or the display area.

5. The mobile terminal of claim 4 , wherein information about the resolution of the display or the display area is previously stored in a memory of the mobile terminal or received from the electronic device.

6. The mobile terminal of claim 1 , wherein the controller receives information about the resolution of contents displayed in the display area from the electronic device through the communication unit and matches the display area and the touch area to each other based on the information about the resolution of the contents.

7. The mobile terminal of claim 1 , further comprising a haptic module configured to generate vibrations, wherein the controller controls the haptic module to generate vibrations when the touch area is touched.

8. The mobile terminal of claim 1 , wherein the mobile terminal is a remote controller.

9. A mobile terminal capable of communicating with an electronic device including a display, comprising:
a touch device;
a communication unit configured to communicate with the electronic device;
a sensing unit configured to sense an orientation of the touch device, wherein the orientation of the touch device is determined based on a rotation of the touch device on an axis perpendicular to a surface of the touch device; and
a controller configured to:
match an entire touch area of the touch device of the mobile terminal with a partial display area of the display included in the electronic device, transmit control information including position information about a second point of the partial display area of the display included in the electronic device corresponding to a first point touched in the touch area of the touch device included in the mobile terminal, intensity information of the first point, and information about the current orientation of the touch device included in the mobile terminal to the electronic device through the communication unit,
in response to detecting that the touch device is disposed in a portrait direction and a touch at the first point, generate the control information including the position information and match a width side and a length side of the display area of the display with a length side and a width side of the touch area of the touch device, respectively, and
in response to detecting that the touch device is disposed in a landscape direction and the touch at the first point, generate the control information including the position information and match the width side and the length side of the display area of the display with the width side and the length side of the touch area of the touch device, respectively,

wherein the control information controls the electronic device to perform different functions according to the intensity information of the first point,
wherein the control information including the position information about the second point of the display area of the display included in the electronic device generated for the touch at the first point indicates a first location on the display area when the touch device is disposed in the portrait direction and indicates a second location on the display area when the touch device is disposed in the landscape direction, and
wherein the first location is different from the second location and both the first location and the second location correspond to the touch at the first point at the touch area of the touch device.

10. The mobile terminal of claim 9 , wherein the sensing unit includes at least one of an acceleration sensor for sensing the rotation of the touch device on the axis perpendicular to the surface of the touch device and a grab sensor arranged around the touch device to sense an external object's touch point on a body of the mobile terminal.

11. An electronic device capable of communicating with a mobile terminal including a touch device, comprising:
a display including a display area;
a communication unit configured to communicate with the mobile terminal; and
a controller configured to
perform a first matching function where the controller matches the display area of the display included in the electr
