Abstract

A mobile terminal and a method of controlling the mobile terminal are provided. The method includes displaying at least one object, which is divided into a plurality of haptic regions, on a touch screen; receiving a touch signal for any one of the haptic regions of the object; and outputting a control signal for controlling a haptic module to generate a haptic effect. Therefore, it is possible for a user to easily determine which of the haptic regions of the object has been touched with the sense of touch.

Claims

1. A method of controlling a mobile terminal, the method comprising:

controlling a touch screen of the mobile terminal, via a controller of the mobile terminal, to display at least one object, wherein each of the at least one object is divided into a plurality of haptic regions;

receiving an initial touch input, via the touch screen, of one haptic region of the plurality of haptic regions of one of the at least one object;

outputting a control signal, via the controller, for controlling a haptic module of the mobile terminal to generate a haptic effect based on the received initial touch input;

generating the haptic effect, via the haptic module, in response to the output control signal, the generated haptic effect corresponding to the one haptic region that received the initial touch input;

receiving another touch input, via the touch screen, during generation of the haptic effect, wherein the another touch input is received away from the one of the at least one object that includes the one haptic region that received the initial touch input; and

ceasing the generation of the haptic effect based on receipt of the another touch input,

wherein the plurality of haptic regions of each of the at least one object includes at least a first haptic region and a second haptic region,

wherein the output control signal controls the haptic module to generate the haptic effect corresponding to the first haptic region of the one of the at least one object when the initial touch input is received at the first haptic region of the one of the at least one object,

wherein the output control signal controls the haptic module to generate the haptic effect corresponding to the second haptic region of the one of the at least one object when the initial touch input is received at the second haptic region of the one of the at least one object, and

wherein the haptic effect corresponding to the first haptic region of the one of the at least one object is different from the haptic effect corresponding to the second haptic region of the one of the at least one object.

2. The method of claim 1, wherein:

each of the at least one object comprises a menu icon, a control icon, a touch key or an image; and

each of the at least one object is associated with control of an operation of the mobile terminal.

3. The method of claim 1, wherein controlling the touch screen to display the at least one object comprises controlling the touch screen to display each of the at least one object such that it is distinguished from other of the at least one object.

4. The method of claim 1, further comprising performing, under control of the controller, a predetermined operation corresponding to the one of the at least one object that includes the one haptic region that received the initial touch input.

5. The method of claim 4, further comprising outputting a control signal, via the controller, for controlling the haptic module to generate a haptic effect corresponding to the predetermined operation during the performance of the predetermined operation.

6. The method of claim 1, wherein at least one of the generated haptic effects is vibration.

7. The method of claim 1, further comprising controlling the touch screen, via the controller, to display an image corresponding to at least one of the generated haptic effects.

8. The method of claim 1, further comprising controlling the touch screen, via the controller, to display a menu for setting the plurality of haptic regions.

9. The method of claim 1, further comprising:

controlling the touch screen, via the controller, to display a menu for setting a type, intensity or pattern of a haptic effect for each of the plurality of haptic regions of the at least one object.

10. The method of claim 1, further comprising:

generating a proximity signal, via a proximity sensor of the mobile terminal, indicating that an entity is approaching the one haptic region of the plurality of haptic regions of the one of the at least one object; and

outputting a control signal, via the controller, for controlling the haptic module to generate the haptic effect corresponding to the haptic region approached by the entity in response to the proximity signal.

11. A mobile terminal, comprising:

a touch screen configured to;

display at least one object, wherein each of the at least one object is divided into a plurality of haptic regions;

receive an initial touch input at one haptic region of the plurality of haptic regions of one of the at least one object; and

receive another touch input away from the one of the at least one object that includes the one haptic region that received the initial touch input;

a haptic module configured to generate a haptic effect; and

a controller configured to output a control signal for controlling the haptic module to;

generate the haptic effect based on the received initial touch input; and

cease the generation of the haptic effect based on receipt of the another touch input,

wherein the plurality of haptic regions of each of the at least one object includes at least a first haptic region and a second haptic region,

wherein the output control signal controls the haptic module to generate the haptic effect corresponding to the first haptic region of the one of the at least one object when the initial touch input is received at the first haptic region of the one of the at least one object, and controls the haptic module to generate the haptic effect corresponding to the second haptic region of the one of the at least one object when the initial touch input is received at the second haptic region of the one of the at least one object, and

wherein the haptic effect corresponding to the first haptic region of the one of the at least one object is different from the haptic effect corresponding to the second haptic region of the one of the at least one object.

12. The mobile terminal of claim 11, wherein:

each of the at least one object comprises a menu icon, a control icon, a touch key or an image; and

each of the at least one object is associated with the control of an operation of the mobile terminal.

13. The mobile terminal of claim 11, wherein the controller is further configured to control the touch screen to display each of the at least one object such that it is distinguished from other of the at least one object.

14. The mobile terminal of claim 11, wherein at least one of the generated haptic effects is vibration.

15. The mobile terminal of claim 11, wherein the controller is further configured to control the touch screen to display an image corresponding to one of the generated haptic effects.

16. The mobile terminal of claim 11, wherein the controller is further configured to control the touch screen to display a menu for setting the plurality of haptic regions.

17. The mobile terminal of claim 11, wherein the controller is further configured to control the touch screen to display a menu for setting a type, intensity or pattern of a haptic effect for each of the plurality of haptic regions of the at least one object.

18. The mobile terminal of claim 11, further comprising:

a proximity sensor configured to determine whether an entity approaches the one haptic region of the plurality of haptic regions of the one of the at least one object and to generate a proximity signal indicating which haptic region is approached by the entity and the degree of proximity between the approaching entity and the approached haptic region,

wherein the controller is further configured to control the haptic module to generate the haptic effect corresponding to the approached haptic region in response to the proximity signal.
