The heat detecting sensor 145 may be provided around the display 151 of the terminal body. The heat detecting sensor 145 may detect the temperature on user's contact with the terminal body and then output the detected temperature to the controller 180.
The output unit 150 may generate an output relevant to a sight sense, an auditory sense, a tactile sense and/or the like. The output unit 150 may include a display 151, an audio output module 152, an alarm 153, a haptic module 154 and/or the like.
The display 151 may display (output) information processed by the terminal 100. For example, in case that the terminal is in a call mode, the display 151 may display a user interface (UI) or a graphic user interface (GUI) associated with the call. If the mobile terminal 100 is in a video communication mode or a photograph mode, the display 151 may display a photographed and/or received picture, a UI or a GUI.
The display 151 may include at least one of a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, and a 3-dimensional display.
The display 151 may have a transparent or light-transmittive type configuration to enable an external environment to be seen through. This may be called a transparent display. A transparent OLED (TOLED) may be an example of a transparent display. A backside structure of the display 151 may also have the light-transmittive type configuration. In this configuration, a user may see an object located behind the terminal body through the area occupied by the display 151 of the terminal body.
At least two displays 151 may also be provided. For example, a plurality of displays may be provided on a single face of the terminal 100 by being built in one body or spaced apart from the single face. Alternatively, each of a plurality of displays may be provided on different faces of the terminal 100.
If the display 151 and a sensor for detecting a touch action (hereafter a touch sensor) are constructed in a mutual-layered structure (hereafter a touchscreen), the display 151 may be used as an input device as well as an output device. For example, the touch sensor may include a touch film, a touch sheet, a touchpad and/or the like.
The touch sensor may convert a pressure applied to a specific portion of the display 151 or a variation of electrostatic capacity generated from a specific portion of the display 151 to an electric input signal. The touch sensor may detect a pressure of a touch as well as a position and size of the touch.
If a touch input is provided to the touch sensor, signal(s) corresponding to the touch input may be transferred to a touch controller. The touch controller may process the signal(s) and then transfer corresponding data to the controller 180. The controller 180 may therefore know which portion of the display 151 is touched.
FIG. 1 shows that the proximity sensor 141 can be provided within the mobile terminal 100 enclosed by the touchscreen or around the touchscreen. The proximity sensor 141 may detect a presence or non-presence of an object approaching a prescribed detecting surface or an object existing around the proximity sensor 141 using an electromagnetic field strength or infrared ray without mechanical contact. The proximity sensor 141 may have a longer durability than the contact type sensor and may also have a greater usage than the contact type sensor.
The proximity sensor 141 may include one of a transmittive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, an infrared proximity sensor and/or the like. If the touchscreen is an electrostatic type, the proximity sensor 141 may detect proximity of a pointer using a variation of an electric field according to the proximity of the pointer. In this case, the touchscreen (touch sensor) may be classified into the proximity sensor.
An action in which a pointer approaches the touchscreen without contacting the touchscreen may be called a proximity touch. An action in which a pointer actually touches the touchscreen may be called a contact touch. The location of the touchscreen proximity-touched by the pointer may be the position of the pointer that vertically opposes the touchscreen when the pointer performs the proximity touch.
The proximity sensor 141 may detect a proximity touch and/or a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state, etc.). Information corresponding to the detected proximity touch action and/or the detected proximity touch pattern may be outputted to the touchscreen.
The audio output module 152 may output audio data that is received from the wireless communication unit 110 in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast receiving mode and/or the like.

The audio output module 152 may include a receiver, a speaker, a buzzer and/or the like.
The alarm 153 may output a signal for announcing an event occurrence of the mobile terminal 100. An event occurring in the mobile terminal 100 may include one of a call signal reception, a message reception, a key signal input, a touch input and/or the like. The alarm 153 may output a signal for announcing an event occurrence by way of vibration or the like as well as a video signal or an audio signal. The video signal may be outputted via the display 151. The audio signal may be outputted via the audio output module 152. The display 151 or the audio output module 152 may be classified as part of the alarm 153.
The haptic module 154 may bring about various haptic effects that can be sensed by a user. Vibration is a representative example for the haptic effect brought about by the haptic module 154. Strength and pattern of the vibration generated from the haptic module 154 may be controllable. For example, vibrations differing from each other may be outputted in a manner of being synthesized together or may be sequentially outputted.
The haptic module 154 may generate various haptic effects including a vibration, an effect caused by such a stimulus as a pin array vertically moving against a contact skin surface, a jet power of air via outlet, a suction power of air via inlet, a skim on a skin surface, a contact of an electrode, an electrostatic power and the like, and/or an effect by hot/cold sense reproduction using an endothermic or exothermic device as well as the vibration.
The haptic module 154 may provide the haptic effect via direct contact. The haptic module 154 may enable a user to experience the haptic effect via muscular sense of a finger, an arm and/or the like. Two or more haptic modules 154 may be provided according to a configuration of the mobile terminal 100.

Here, the type or scheme of the signal of selecting a specific icon from the plurality of icons 12a, 12b, 12c, 12d and 12e, received in step S400, may differ from that of the selection signal received in step S120 of the above-mentioned first embodiment of the present invention and the selection signal received in step S300 of the second embodiment of the present invention.
For example, when the selection signal received in step S120 of FIG. 2 may be a short touch signal and the selection signal received in step S300 may be a long touch signal, the selection signal received in step S400 may corresponds to two short touches applied to a specific icon from among the plurality of icons 12a, 12b, 12c, 12d and 12e. 
The schemes (or types) of the selection signals received in steps S120, S300 and S400 are not limited to the above description. The selection signals received in steps S120, S300 and S400 may be differently set and are not limited to a specific example.
The controller 180 may display a list of transmitted messages corresponding to the specific icon on the touchscreen 151 (S410).
For example, when the currently selected message format corresponds to the SNS message format, the controller 180 can display a list of transmitted messages having the SNS message format on the touchscreen 151 when the list icon 13 is selected as described in FIG. 13.
FIG. 14 shows an example of a list 35 of transmitted messages having the SNS (Facebook in the present embodiment) message format.
When the currently selected message format corresponds to the SNS message format, if a specific icon from among the plurality of icons 12a, 12b, 12c, 12d and 12e is short-touched twice, the controller 180 can display a list of transmitted messages having a message format corresponding to the specific icon on the touchscreen 151.
The controller 180 may receive a signal of selecting a specific item included in the list of transmitted messages while the list of transmitted messages having the specific message format is displayed on the touchscreen 151 (S420).
The controller 180 checks whether the selected specific item corresponds to the SNS message format (S430). When the selected specific item corresponds to the SNS message format, the controller 180 may download the item selected in step S420 from a corresponding server and display the item on the touchscreen 151 (S440).
Referring to FIG. 15, the user can select a specific item “Peter” from a list of transmitted SNS messages.
The controller 180 may access Facebook to download content 40 corresponding to the selected specific item “Peter” and display the content 40 on the touchscreen 151, as shown in FIG. 16, upon selection of the specific item “Peter”
That is, the content 40 shown in FIG. 16 is a message in the SNS (Facebook in the current embodiment) message format, which has been sent to “Peter” by the user of the mobile terminal 100.
If the specific item selected in step S420 does not correspond to the SNS message format, information about the selected item, for example, transmission time, a destination such as a receiving part or an Internet address, etc. may be displayed on the touchscreen 151 in step S450.
The user may input information on a specific receiving part registered in a contact book to the destination input window 10.
The controller 180 may display only at least one icon corresponding to destination information corresponding to the specific receiving part, from among the plurality of icons 12a, 12b, 12c, 12d and 12e, on the message creation screen.
For example, if destination information on the specific receiving part input by the user, which is stored in the contact book, does not include SNS information, the SNS icons 12d and 12e are not displayed on the message creation screen.
The method of controlling a mobile terminal may be written as computer programs and may be implemented in digital microprocessors that execute the programs using a computer readable recording medium.
