The mobile terminal 100 may also include at least two displays 151. For example, the mobile terminal 100 may include a plurality of displays 151 that are arranged on a single face at a predetermined distance or integrated displays. The plurality of displays 151 may also be arranged on different sides.
When The display unit 151 and a sensor sensing touch (hereafter referred to as a touch sensor) form a layered structure that is referred to as a touch screen, The display unit 151 may be used as an input device in addition to an output device. The touch sensor may be in the form of a touch film, a touch sheet, and/or a touch pad, for example.
The touch sensor may convert a variation in pressure applied to a specific portion of The display unit 151 or a variation in capacitance generated at a specific portion of The display unit 151 into an electric input signal. The touch sensor may sense pressure of touch as well as position and area of the touch.
When the user applies a touch input to the touch sensor, a signal corresponding to the touch input may be transmitted to a touch controller. The touch controller may then process the signal and transmit data corresponding to the processed signal to the controller 180. Accordingly, the controller 180 may detect a touched portion of The display unit 151.
The proximity sensor 141 (of the sensing unit 140) may be located in an internal region of the mobile terminal 100, surrounded by the touch screen, and/or near the touch screen. The proximity sensor 141 may sense an object approaching a predetermined sensing face or an object located near the proximity sensor 141 using an electromagnetic force or infrared rays without having mechanical contact. The proximity sensor 141 may have a lifetime longer than a contact sensor and may thus have a wide application in the mobile terminal 100.
The proximity sensor 141 may include a transmission type photo-electric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photo-electric sensor, a high-frequency oscillating proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and/or an infrared proximity sensor. A capacitive touch screen may be constructed such that proximity of a pointer is detected through a variation in an electric field according to the proximity of the pointer. The touch screen (touch sensor) may be classified as a proximity sensor 141.
For ease of explanation, an action of the pointer approaching the touch screen without actually touching the touch screen may be referred to as a proximity touch and an action of bringing the pointer into contact with the touch screen may be referred to as a contact touch. The proximity touch point of the pointer on the touch screen may correspond to a point of the touch screen at which the pointer is perpendicular to the touch screen.
The proximity sensor 141 may sense the proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch velocity, a proximity touch time, a proximity touch position, a proximity touch moving state, etc.). Information corresponding to the sensed proximity touch action and proximity touch pattern may then be displayed on the touch screen.
The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal receiving mode, a telephone call mode or a recording mode, a speech recognition mode and a broadcasting receiving mode. The audio output module 152 may output audio signals related to functions, such as a call signal incoming tone and a message incoming tone, performed in the mobile terminal 100. The audio output module 152 may include a receiver, a speaker, a buzzer, and/or the like. The audio output module 152 may output sounds through an earphone jack. The user may hear the sounds by connecting an earphone to the earphone jack.

If the pointer is positioned to be spaced apart by the distance longer than the distance d1 but shorter than a distance d2 on the touch screen, this position is recognized as a proximity touch with a second proximity depth. Also, if the pointer is positioned to be spaced apart by the distance longer than the distance d2 but shorter than a distance d3, this position is recognized as a proximity touch with a third proximity depth. If the pointer is positioned to be spaced apart by longer than the distance d3 on the touch screen, this position is recognized that the proximity touch has been released.
Accordingly, the controller 180 can recognize the proximity touches as various input signals according to the proximity depths and proximity positions of the pointer, and control various operations according to the various input signals.
Binocular parallax refers to the apparent difference in position of an object as seen separately by one eye, and then by the other. When the brain of a person combines an image viewed through the left eye and an image viewed through the right eye, the combined image is seen as a stereoscopic image by the person.
In the following description, the phenomenon that a person feels stereoscopic effect according to binocular parallax is called ‘stereoscopic vision’ and an image that generates stereoscopic vision is called ‘stereoscopic image’. The stereoscopic image can use a moving image or a still image.
An object included in a stereoscopic image is referred to as ‘stereoscopic object’ and content generated such that it causes stereoscopic vision is referred to as ‘stereoscopic content’. The stereoscopic content may include a stereoscopic image, a stereoscopic object, etc.
Methods of displaying a stereoscopic image using the binocular parallax are classified into a stereoscopic method and an auto-stereoscopic method.
The stereoscopic method includes a method using shades having wavelength selectivity, a patterned retarder method using light-shielding effect according polarization difference, and a field sequential glasses method that alternately provides left and right images within the afterimage lag time of eyes. In addition, there is a method that sets filters having difference transmittance for left and right eyes and obtains stereoscopic effect with respect to motion to the left and right according to a time difference of the visual system, caused by the transmittance difference.
The auto-stereoscopic method that causes stereoscopic effect at the side of an image display plane instead of an observer includes a method using a parallax barrier, a method using a lenticular lens, a method using a microlens array, etc.

A method of controlling the mobile terminal 100 according to a first embodiment of the invention and operations of the mobile terminal 100 to implement the control method will now be described in detail with reference to
Referring to
For example, the specific mode may be a mode in which information or a command can be received from a user through a touch operation of the user via the touch screen 151. This mode can be called an activation mode. In the case of a terminal employing a touch screen, the touch screen is generally controlled to be locked to prevent an erroneous operation when the user does not manipulate the terminal for a predetermined time.
A case in which the specific mode is the activation mode of the touch screen 151 will now be described as an example. However, it is noted that the specific mode is not limited to the activation mode.
Upon reception of a control input for requesting the locked specific mode to be unlocked, the controller 180 arranges a plurality of figures for receiving an unlocking pattern on the touch screen (S102).
The unlocking pattern is used as authentication information for determining whether to unlock the specific mode and may be generated in the form of at least one trajectory that connect some of the plurality of figures or in the order of touching some of the plurality of figures.
When the plurality of figures for receiving the unlocking pattern is initially arranged in step S102, the plurality of figures may be arranged in a first area.
Referring to
Referring back to
Referring to
When the user drags the first area 9a, the controller 180 re-sets an area in which the figures will be displayed on the basis of the direction and distance of the drag. That is, the controller 180 sets a second area 9b reduced from the first area 9a as the area in which the figures will be displayed and rearranges the figures in the second area 9b.
Referring back to
When the received pattern corresponds to a previously stored unlocking pattern (S106), the controller 180 unlocks the specific mode (S106). That is, the controller 180 controls the mobile terminal 100 to operate in the activation mode of the touch screen 151.
When the user inputs a pattern using the figures in step S105, the controller 180 can display the touched figures such that the touched figures are distinguished from other figures or display a trajectory formed by the touched figures on the screen to allow the user to intuitively recognize the pattern input by him/her.
Referring to
The pattern 10a can include the order of touching the figures a1 to a5 by the user or a trajectory formed by the touched figures a1 to a5.
The controller 180 compares the received pattern 10a with the previously stored unlocking pattern and unlocks the touch screen 151 when the two patterns correspond to each other.
As described above, according to the first embodiment of the present invention, it is possible to change the area in which the figures for receiving the unlocking pattern are displayed according to user input. Accordingly, the user can move the figures to a position at which the user conveniently inputs the unlocking pattern. Particularly, when the user has difficulty in inputting the unlocking pattern with one hand because the touch screen of the mobile terminal 100 is large, the user can move the figures to a position at which he/she can easily input the pattern, thereby improving user convenience.
While display positions of the figures are moved while the figures are displayed when an unlocking request for the specific mode is received from the user in the first embodiment of the present invention, the present invention is not limited thereto. According to exemplary embodiments of the present invention, the controller 180 can change the display positions of the figures using an additional screen for setting the display positions of the figures. In this case, the controller 180 displays the figures in an area set through the additional screen at the user's request for unlocking the specific mode.
Furthermore, while the display positions of the figures are changed using drag input in the first embodiment of the present invention, the present invention is not limited thereto. According to the present invention, the controller 180 can change the display positions of the figures on the basis of inputs in different forms, such as button manipulation, tapping, tilting of the mobile terminal 100, etc.

Upon reception of a control input for requesting the specific mode to be unlocked, the controller 180 arranges a plurality of figures for receiving an unlocking pattern (S202).
The controller 180 can display tridimensionality and arrange figures on the surface of the tridimensionality in step S202. In this case, the controller 180 can receive an unlocking pattern corresponding to a trajectory formed by some figures arranged on the surface of the tridimensionality or the order of touching the figures.
The controller 180 may combine the figures in the form of tridimensionality and display the figures in step S202. In this case, the controller 180 can receive the unlocking pattern corresponding to arrangement or arrangement positions of the figures.
When the controller 180 arranges the figures on the surface of the tridimensionality or combines the figures to display tridimensionality in step S202, it is possible to achieve 3-dimensional effect of the tridimensionality by controlling display characteristics such as shadow or acquire 3-dimensional effect of the tridimensionality using binocular parallax by activating the panel for producing stereoscopic vision.
Referring to
The spherical tridimensionality can be rotated and the composition of the figures displayed on the screen can be changed as the spherical tridimensionality rotates. That is, the surface of the sphere 12 displayed on the screen is changed when the sphere 12 rotates, and thus the composition of the figures displayed on the screen can be changed to correspond to the changed surface.
When the figures are arranged on the surface of the tridimensionality, the controller 180 may control a display characteristic such as color to be different for the respective figures or respectively allocating different identification information to the respective figures such that the figures can be distinguished even when the composition of the figures is changed according to rotation of the tridimensionality.

For example, the specific input can be applied through a touch gesture. In this case, the controller 180 can rearrange the figures displayed on the screen on the basis of a touch position on the screen, a drag direction, etc.
Furthermore, the specific input can be applied according to a motion of the mobile terminal 100. In this case, the controller 180 can rearrange the figures on the basis of the direction and degree of the motion of the mobile terminal 100.
When the figures are arranged on the surface of the tridimensionality, the controller 180 can rotate the tridimensionality on which the figures are arranged upon receiving the specific input in steps S203 and S204. Accordingly, the surface of the tridimensionality displayed on the screen is changed and the figures corresponding to the changed surface are displayed on the screen.
Furthermore, the controller 180 can change arrangement of the figures upon receiving the specific input in steps S203 and S204. That is, the controller 180 can change arrangement of at least some figures when the specific input is received.

Furthermore, the controller 180 may receive the pattern on the basis of arrangement or arrangement positions of the figures in step S205.
According to the above-described second embodiment of the present invention, the mobile terminal 100 can rotate tridimensionality or change arrangement of figures three-dimensionally. Accordingly, the user can have fun inputting the unlocking pattern, compared to the case in which the user inputs the pattern using fixed figures.

The controller 180 can receive the pattern according to contact touch or proximity touch on the basis of the depth of each figure according to stereoscopic vision thereof in step S303.
For example, when the figures are displayed in different depths, as shown in
In this case, when some figures are touched according to contact touch or proximity touch, the controller 180 can receive the pattern corresponding to the trajectory generated on the basis of the order of touching the figures or the order of touching the figures.
Furthermore, when figures are displayed such that the figures are seen as if they are protruded from the display plane, as shown in
In this case, the controller 180 can change the depth of the figures touched according to proximity touch and receive the pattern corresponding to the changed depth of the figures.
