When such an object is displayed on the display unit 151, the area in which the object is displayed is divided into a first area A in the center and a second area B adjacent to the border, as shown in Fig. 5 (a) , And a tactile effect having different intensities or patterns in the first region (A) and the second region (B) can be generated. For example, when the second region B is touched, a first vibration is outputted, and when the first region A is touched, a second vibration larger than the first vibration is outputted.

If the proximity area and the haptic area are simultaneously set in the area where the object is displayed, the haptic area where the tactile effect is generated and the proximity area where the proximity signal is detected can be set to be different from each other. That is, the haptic region may be set narrower than the adjacent region, or the haptic region may be set wider than the adjacent region. For example, in FIG. 5A, the area including the first area A and the second area B may be a close area, and the first area A may be set as a haptic area.

5A, the area where the object is displayed is divided into three areas A, B, and C, or as shown in FIG. 5A, So that a tactile effect having different intensities or patterns can be generated for each of the divided regions. Even in the case where the area in which one object is displayed is divided into three or more areas, the haptic area and the adjacent area can be set differently according to the use environment.

Objects can be displayed in a rectangle shape or in various other shapes in addition to a circle shape. In addition, when dividing an area in which an object is displayed for setting a haptic area or an adjacent area, various methods such as division in a horizontal direction and a vertical direction, radial division, and division in a combination mode can be used in addition to a concentric division have.

The size of the adjacent area may be changed according to the degree of proximity to the display unit 151. [ That is, as shown in (a) of FIG. 5B, the proximity area may be gradually reduced to 'C', 'B', and 'A' depending on the degree of proximity to the display unit 151, It may be configured to be larger. Also in this case, the haptic area in which the tactile effect occurs, such as the 'H' area shown in FIG. 5B (b), can be configured to have a constant size regardless of the proximity.

6 is a flowchart illustrating a method of controlling a mobile terminal according to a first embodiment of the present invention. Referring to FIG. 6, a haptic mode such as a vibration output is set according to a user command or the like (S200). The haptic mode may be configured to be set to the default, or may be configured to be set according to a user command. In addition, a separate menu may be provided for setting and releasing the haptic mode.

After setting the haptic mode, the control unit 180 displays the first screen corresponding to the selected menu or operation on the display unit 151 (S202). Then, the control unit 180 checks whether a display change occurs in the first screen displayed on the display unit 151 (S204). If a display change occurs in the first screen as a result of the inspection, the control unit 180 outputs a control signal corresponding to the display change that has occurred (S206). At this time, the output control signal is a signal that can control the haptic module 157 to generate a tactile effect corresponding to the display change.

In addition, when the indicator icon or other icon displayed on the first screen is newly displayed or disappears, the display magnification of the first screen is changed when the shape or the like of the icon displayed on the first screen changes Means that the contents displayed on the screen are changed according to the change of the operation state or the like when the first screen is rotated and displayed and the shape of the image displayed on the first screen is changed.

The control signal output from the control unit 180 is transmitted to the haptic module 157. The haptic module 157 generates a corresponding haptic effect according to the control signal output from the control unit 180 at step S224.

If the pop-up screen is displayed on the first screen in step S208, the controller 180 outputs a control signal corresponding to the pop-up screen displayed in step S210. In response to the control signal, the haptic module 157 displays a pop- A tactile effect corresponding to the display of the screen is generated (S224).

The control unit 180 outputs a control signal corresponding to the second screen displayed (S214), and the control unit 180 The haptic module 157 is controlled in accordance with the control signal output from the controller 160, and a tactile effect corresponding to the display of the second screen is generated (S224).

The control unit 180 outputs a control signal corresponding to the change in brightness of the screen (S218), and if the brightness of the screen displayed on the display unit 151 is changed (S216) 157 are controlled, and a tactile effect corresponding to the changed screen brightness is generated (S224). The control unit 180 outputs a control signal corresponding to a change in voice or sound volume (S222), and the haptic module 157 is controlled in accordance with the output control signal, A tactile effect corresponding to the change in volume occurs (S224). In addition, the tactile effect can be generated according to the value set in the menu for setting the brightness of the screen or setting the volume or the like. For example, when the brightness of the screen is gradually increased, the intensity of the vibration gradually increases. On the contrary, when the brightness of the screen gradually increases, the vibration device gradually becomes weaker. In addition, when the operating state or the like is changed according to the setting items, a corresponding tactile effect can be generated.
