     1. Field of the Invention 
     The present invention relates to a mobile terminal, and in particular to a mobile terminal providing various haptic effects. 
     2. Description of the Related Art 
     Mobile terminals are portable devices, which can provide users with various services such as a voice calling service, a video calling service, an information input/output service, and a data storage service. 
     As the types of services provided by mobile terminals become more diversified, an increasing number of mobile terminals are being equipped with various complicated functions such as capturing photos or moving pictures, playing music files or moving image files, providing game programs, receiving broadcast programs and providing wireless internet services. As such, mobile terminals have evolved into multimedia players. 
     Various attempts have been made to realize such complicated functions as hardware devices or software programs. For example, various user interface (UI) environments, in which users are allowed to easily search for and choose desired functions, have been developed. In addition, the demand for various designs for mobile terminals, such as a double-sided liquid crystal display (LCD) or a full touch screen, has steadily increased due to the growing perception that mobile terminals represent personal individuality. 
     However, there is a restriction in allocating sufficient space for a UI, such as a display device or a keypad, of a mobile terminal without compromising the mobility and the portability of a mobile terminal. In addition, there is also a restriction in properly responding to various user commands due to limited UI space. Therefore, it is useful to develop ways to control the operation of a mobile terminal using a new data input/output method, other than an existing visual representation-based simple data input/output method, to efficiently use various functions provided by the mobile terminal.

It is to be understood by those of ordinary skill in this technological field that other embodiments may be utilized, and structural, electrical, as well as procedural changes may be made without departing from the scope of the present invention. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or similar parts. 
     The term “mobile terminal,” as used herein, may indicate a mobile phone, a smart phone, a laptop computer, a digital broadcast receiver, a personal digital assistant (PDA), a portable multimedia player (PMP), or a navigation device. In this disclosure, the terms “module” and “unit” can be used interchangeably. 
       FIG. 1  illustrates a block diagram of a mobile terminal  100  in accordance with various embodiments of the present invention. As shown in  FIG. 1 , the mobile terminal  100  includes a wireless communication unit  110 , an audio/video (A/V) input unit  120 , a user input unit  130 , a sensing unit  140 , an output unit  150 , a memory  160 , an interface unit  170 , a controller  180 , and a power supply unit  190 . It should be understood that the mobile terminal  100  may include additional or fewer components than those shown in  FIG. 1 . It should also be understood that one or more of the components shown in  FIG. 1  can be incorporated within a single component and, alternatively, one or more of the components shown in  FIG. 1  can be configured using multiple components. 
     The wireless communication unit  110  may include a broadcast reception module  111 , a mobile communication module  113 , a wireless internet module  115 , a short-range communication module  117 , and a global positioning system (GPS) module  119 . 
     The broadcast reception module  111  receives broadcast signals and/or broadcast-related information from an external broadcast management server via a broadcast channel. The broadcast channel can be a satellite channel or a terrestrial channel. The broadcast management server can be a server that generates and transmits broadcast signals and/or broadcast-related information, or a server that receives a previously-generated broadcast signal and/or previously-generated broadcast-related information and transmits the previously-generated broadcast signal and/or previously-generated broadcast-related information to the mobile terminal  100 . 
     For example, the broadcast signal can be a TV broadcast signal, a radio broadcast signal, a data broadcast signal, the combination of a data broadcast signal and a TV broadcast signal or the combination of a data broadcast signal and a radio broadcast signal. 
     The broadcast-related information can include broadcast channel information, broadcast program information and/or broadcast service provider information. The broadcast-related information can be provided to the mobile terminal  100  through a mobile communication network. In such a case, the broadcast-related information can be received by the mobile communication module  113 , rather than by the broadcast reception module  111 . 
     The broadcast-related information can take various forms. For example, the broadcast-related information can have the form of an electronic program guide (EPG) of the digital multimedia broadcasting (DMB) standard, or an electronic service guide (ESG) of the digital video broadcast-handheld (DVB-H) standard. 
     The broadcast reception module  111  can be configured to receive the broadcast signal using various types of broadcasting systems, such as digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), the data broadcasting system known as media forward link only (MediaFLO™), digital video broadcast-handheld (DVB-H), or integrated services digital broadcast-terrestrial (ISDB-T) systems. The broadcast reception module  111  is configured to be suitable for every broadcast system that provides a broadcast signal as well as the above-mentioned digital broadcast systems. 
     The broadcast signal and/or the broadcast-related information received via the broadcast reception module  111  can be stored in a storage medium, such as the memory  160 . 
     The mobile communication module  113  transmits and/or receives wireless signals to and/or from at least a base station, an external terminal, or a server through a mobile communication network. Such wireless signals can include various types of data according to whether the mobile terminal  100  transmits or receives voice call signals, video call signals, text messages, or multimedia messages. 
     The wireless internet module  115  supports wireless Internet access for the mobile terminal  100 . For example, the wireless internet module  115  can be embedded in the mobile terminal  100  or installed in an external device. The wireless Internet technology implemented by the wireless internet module  115  can be a wireless local area network (WLAN), Wi-Fi, Wireless Broadband (WiBro), World Interoperability for Microwave Access (WiMAX), or High Speed Downlink Packet Access (HSDPA). 
     The short-range communication module  117  is a module for supporting short-range communication. For example, the short-range communication module  117  can be configured to communicate using short range communication technology, such as Bluetooth™, radio frequency identification (RFID), Infrared Data Association (IrDA), Ultra-wideband (UWB), or ZigBee™. 
     The GPS module  119  can receive position information from a plurality of GPS satellites. 
     As shown in  FIG. 1 , the A/V input unit  120  can include an image capture device, such as a camera  121 , and a device for detecting sounds, such as microphone  123 . For example, the camera  121  can process image data of still pictures or video obtained via an image sensor of the camera  121  in a video telephony or photo capture mode of the mobile terminal  100 . The processed image frames can be displayed on a visual output device, such as the display module  151 . 
     The A/V input unit  120  can be used to receive audio signals or video signals. The image frames processed by the camera  121  can be stored in the memory  160 , or transmitted via the wireless communication unit  110  to an external device. Other embodiments of the mobile terminal  100  can include more than one camera  121 . 
     The microphone  123  can receive external sound signals during a call mode, a recording mode, or a voice recognition mode, and can convert the sound signals into electrical sound data. For example, when the mobile terminal  100  is in the call mode, the mobile communication module  113  can convert the electrical sound data into data for transmission to a mobile communication base station and output the data obtained by the conversion. The microphone  123  can include various types of noise canceling or suppression algorithms for removing any undesirable noise in the received external sound signals. 
     The user input unit  130  can be a user input device configured to generate input data based on inputs entered by a user to control various operations of the mobile terminal  100 . For example, the user input unit  130  can include a keypad, a dome switch, a jog wheel, a jog switch, and/or a touch pad, such as a touch sensitive member that detects changes in resistance, pressure, voltage, or capacitance. 
     When the user input  130  is implemented as a touch pad and overlaid with the display module  151  in a layered manner, a “touch screen” may be formed allowing the display module  151  to function both as an input device and an output device. 
     The sensing unit  140  determines a current state of the mobile terminal  100 , such as an opened or closed state, the relative positions of the components of the mobile terminal  100  and whether the mobile terminal  100  is placed in contact with a user. The mobile terminal  100  can generate a sensing signal based on the current state of the mobile terminal  100  for controlling the operation of the mobile terminal  100 . For example, when the mobile terminal  100  is implemented as a slider-type mobile phone, the sensing unit  140  can be configured to determine whether the mobile terminal  100  is opened or closed. In addition, the sensing unit  140  can determine whether the power supply unit  190  supplies power and whether the interface unit  170  is connected to an external device. 
     The sensing unit  140  can include a proximity sensor  141 , a pressure sensor  143  and a motion sensor  145 . The proximity sensor  141  can determine the presence or absence of an object nearby and approaching the mobile terminal  100  without any physical contact with the object. More specifically, the proximity sensor  141  can determine the presence or absence of an object by detecting a change in an alternating magnetic field or the rate of change of static capacitance. The sensing unit  140  may include two or more proximity sensors  141 . 
     The pressure sensor  143  can determine whether any pressure is being applied to the mobile terminal  100  or can measure the level of any pressure being applied to the mobile terminal  100 . The pressure sensor  143  can be installed at a location in the mobile terminal  100  where the detection of pressure is desired. For example, the pressure sensor  143  can be installed in the display module  151 . In such a case, a typical touch input can be differentiated from a pressure touch input using data provided by the pressure sensor  143 , since a pressure touch input is generally applied with a greater level of pressure than a typical touch input. In addition, when a pressure touch input on the display module  151  is detected, it is possible to determine the level of pressure applied to the display module  151  upon the detection of a pressure touch input based on data provided by the pressure sensor  143 . 
     The motion sensor  145  can determine the location and any motion of the mobile terminal  100  using an acceleration sensor or a gyro sensor. 
     An acceleration sensor is a device for detecting variations in acceleration and converting the variation into an electrical signal. With recent developments in micro-electromechanical system (MEMS) technology, acceleration sensors have been widely used in various products for various purposes. For example, an acceleration sensor can be installed in an airbag system in an automobile to detect a collision. Alternatively, an acceleration sensor can be used as an input device in a computer game controller and configured to sense the motion of the human hand during play of a computer game. In one embodiment, several acceleration sensors can be installed in the mobile terminal  100  to represent various axial directions. Alternatively, only one acceleration sensor representing a Z axis may be installed in the mobile terminal  100 . 
     Gyro sensors are sensors for measuring angular velocity, and can determine the relative direction of rotation of the mobile terminal  100  with respect to a reference direction. 
     The output unit  150  can be configured to output audio signals, video signals and alarm signals. In one embodiment, the output unit  150  can include the display module  151 , an audio output module  153 , an alarm module  155 , and a haptic module  157 . 
     The display module  151  can display information processed by the mobile terminal  100 . For example, when the mobile terminal  100  is in a call mode, the display module  151  can display a user interface (UI) or a graphic user interface (GUI) for making or receiving a call. For example, if the mobile terminal  100  is in a video call mode or an image capturing mode, the display module  151  can display a UI or a GUI for capturing or receiving images. 
     When the display module  151  and the user input unit  130  form a layered structure and are thus implemented as a touch screen, the display module  151  can be used as an output device, as well as an input device. When the display module  151  is implemented as a touch screen, the display module  151  can also include a touch screen panel and a touch screen panel controller. 
     The touch screen panel, for example, can be a transparent panel attached to the exterior of the mobile terminal  100  and can be connected to an internal bus of the mobile terminal  100 . The touch screen panel can detect whether the touch screen panel is being contacted by a user. Once a touch input to the touch screen panel is detected, the touch screen panel can transmit signals corresponding to the touch input to the touch screen panel controller. The touch screen panel controller can process the signals transmitted by the touch screen panel, and can transmit the processed signals to the controller  180 . The controller  180  can determine whether a touch input has been generated and which part of the touch screen panel has been touched based on the processed signals transmitted by the touch screen panel controller. 
     In one embodiment, the display module  151  can include electronic paper (e-paper). E-paper is a type of reflective display technology that can achieve a high resolution, wide viewing angles and can maintain a displayed image even after power is no longer supplied. E-paper can be implemented on any type of substrate, such as plastic, metallic or paper. In addition, e-paper can reduce the power consumption of the mobile terminal  100 , because it does not require a backlight assembly. The display module  151  may be implemented as e-paper by using electrostatic-charged hemispherical twist balls, electrophoretic deposition, or microcapsules. 
     The display module  151  can include at least a liquid crystal display (LCD), a thin film transistor (TFT)-LCD, an organic light-emitting diode (OLED), a flexible display, or a three-dimensional (3D) display. In one embodiment, the mobile terminal  100  can include two or more display modules  151 . For example, the mobile terminal  100  can include an external display module (not shown) and an internal display module (not shown). 
     The audio output module  153  can output audio data received by the wireless communication unit  110  during a call reception mode, a call mode, a recording mode, a voice recognition mode, or a broadcast reception mode or can output audio data stored in the memory  160 . In addition, the audio output module  153  can output various sound signals associated with the functions of the mobile terminal  100 , such as receiving a call or a message. The audio output module  153  can include, for example, a speaker and a buzzer. 
     The alarm module  155  can output an alarm signal indicating the occurrence of an event in the mobile terminal  100 , such as receiving a call signal, receiving a message, or receiving a key signal. The alarm signal can be, for example, an audio signal, a video signal, and/or a vibration signal. For example, the alarm module  155  can output an alarm signal upon receiving a call signal or a message. In addition, the alarm module  155  can receive a key signal and output an alarm signal as feedback to the key signal. Once an alarm signal is output by the alarm module  155 , the user can be notified that an event has occurred. An alarm signal for notifying the user of the occurrence of an event can also be output by the display module  151  or the audio output module  153 . 
     The haptic module  157  can provide various haptic effects (such as vibrations) that can be detected by the user. When the haptic module  157  generates vibrations, the intensity and the pattern of the vibrations can be altered. The haptic module  157  can synthesize different vibration effects and can output the result. Alternatively, the haptic module  157  can sequentially output different vibration effects. 
     The haptic module  157  can provide various haptic effects other than vibrations, such as a stimulation caused by an array of vertically moving pins that are in contact with the skin of the user, a stimulation caused by a discharge or suction of air through a discharge hole or a suction hole, a stimulation involving an application of a stimulus to the surface of the user&#39;s skin, a stimulation caused by contact with an electrode, a stimulation caused by an electrostatic force, and a stimulation caused by the application of cold and warm temperatures using an element capable of absorbing or radiating heat. 
     The haptic module  157  can enable a user to feel haptic effects via a kinesthetic sense of her fingers or arms. For example, the mobile terminal  100  can include at least two haptic modules  157 . 
     The memory  160  can store various programs that are used for the processing and operations performed by the controller  180 . In addition, the memory  160  can store various data such as a phonebook, messages, still images, or moving images. 
     For example, the memory  160  can include at least one type of storage medium, such as a flash memory, a hard disk, a multimedia card, a micro type memory, a card type memory, such as a secure digital (SD) card or extreme digital (XD) card, a random access memory (RAM), or a read-only memory (ROM). In other embodiments, the memory  160  can be a network storage device that can be accessed by the mobile terminal  100  via a network, such as the Internet. 
     The interface unit  170  can interface with an external device that can be connected to the mobile terminal  100 . For example, the interface unit  170  can be a wired/wireless headset, an external battery charger, a wired/wireless data port, a card socket for a memory card, a subscriber identification module (SIM)/user identity module (UIM) card, an audio input/output (I/O) terminal, a video I/O terminal, or an earphone. The interface unit  170  can receive data from an external device or can be used to receive power from an external device. The interface unit  170  can transmit data provided by an external device to other components in the mobile terminal  100  or can transmit data provided by other components in the mobile terminal  100  to an external device. 
     When the mobile terminal  100  is connected to an external cradle (not shown in  FIG. 1 ), power can be supplied from the external cradle to the mobile terminal  100  through the interface unit  170 . In addition, various command signals can be transmitted from the external cradle to the mobile terminal  100  through the interface unit  170 . 
     The controller  180  can control the general operations of the mobile terminal  100 . For example, the controller  180  can perform various control operations related to making and receiving a voice call, transmitting and receiving data, or making and receiving a video call. 
     The controller  180  can include a multimedia module  181  for reproducing or playing back multimedia data. In one embodiment, the multimedia module  181  can be implemented as a hardware device and can be installed in the controller  180 . In another embodiment, the multimedia module  181  can be implemented as a software program. 
     The power supply unit  190  can be an external power source or an internal power source and supplies power to other components in the mobile terminal  100 . 
     The mobile terminal  100  can include a wired/wireless communication system and a satellite-based communication system. The mobile terminal  100  can be configured to operate in a communication system transmitting data as frames or packets. 
     In one embodiment, the mobile terminal  100  can be a slider-type mobile phone. However, in other embodiments, the present invention can be applied to various other types of mobile phones. 
       FIG. 2  illustrates a front perspective view of the mobile terminal  100  in accordance with various embodiments of the invention. 
     As shown in  FIG. 2 , the mobile terminal  100  includes a first body  100 A and a second body  100 B, where the second body  100 B is configured to slide relative to the first body  100 A. 
     When the first body  100 A and the second body  100 B completely overlap each other, the mobile terminal  100  is referred to as being in the closed configuration. On the other hand, as shown in  FIG. 2 , when the first body  100 A slides relative to the second body  100 B, such that a portion of the second body  100 B is partially exposed, the mobile terminal  100  is referred to as being in the open configuration. 
     When the mobile terminal  100  is in the closed configuration, the mobile terminal  100  can generally operate in a standby mode and can be released from the standby mode in response to user manipulation. On the other hand, when the mobile terminal  100  is in the open configuration, the mobile terminal  100  can generally operate in a call mode and can be switched to the standby mode either manually in response to a user manipulation or automatically after the lapse of a predefined period of time. 
     As shown in  FIG. 2 , the exterior of the first body  100 A includes a first front case  100 A- 1  and a first rear case  100 A- 2 . Various electronic components can be installed in the space (not shown in  FIG. 2 ) between the first front case  100 A- 1  and the first rear case  100 A- 2 . At least one intermediate case can be additionally disposed between the first front case  100 A- 1  and the first rear case  100 A- 2 . 
     For example, the first front case  100 A- 1  and the first rear case  100 A- 2  can be formed by injection molding of a synthetic resin. Alternatively, the first front case  100 A- 1  and the first rear case  100 A- 2  can be formed of a metal, such as stainless steel (STS) or titanium (Ti). 
     As shown in  FIG. 2 , a display module  151 , a first audio output module  153   a , a first camera  121   a , and a first user input unit  130   a  are disposed on the first front case  100 A- 1 . The display module  151  can be, for example, an LCD or an OLED. 
     In one embodiment, the display module  151  can be configured as a touch screen by incorporating the user input unit  130  in a layered manner. Therefore, a user can use the display module  151  to input information by touching the display module  151 . 
     As shown in  FIG. 2 , the exterior of the second body  100 B includes a second front case  100 B- 1  and a second rear case  100 B- 2 . A second user input unit  130   b  can be disposed on the second body  100 B. For example, the second user input  130   b  can be disposed at the front of the second front case  100 B- 1 . A third user input unit  130   c , a fourth user input unit  130   d , the microphone  123  and the interface unit  170  can be located on the second front case  100 B- 1  or the second rear case  100 B- 2 . 
     The first through fourth user input units  130   a  through  130   d , a fifth user input unit  130   e , and a sixth user input unit  130   f  can be collectively referred to as the user input unit  130 . The user input unit  130  can utilize various manipulation methods which offer a tactile feedback to the user. 
     The user input unit  130   a  can allow a user to input such commands as “start,” “end,” and “scroll” to the mobile terminal  100 . The second user input unit  130   b  can allow a user to input various numerals, characters or symbols. The third and fourth user input units  130   c  and  130   d  can be used as hot keys for activating certain functions of the mobile terminal  100 . The user input unit  130  can also allow a user to choose an operating mode and can serve as a hot key for activating certain functions of the mobile terminal  100 . 
     The microphone  123  can be configured to receive the user&#39;s voice or other sounds. 
       FIG. 3  illustrates a rear perspective view of the mobile terminal  100  in accordance with various embodiments of the invention. As shown in  FIG. 3 , the fifth user input unit  130   e , which is implemented as a wheel type input, and the second camera  121   b  can be disposed at the rear of the second rear case  100 B- 2  of the second body  100 B, and a sixth user input unit  130   f  can be disposed on one side of the second body  100 B. 
     The second camera  121   b  shown in  FIG. 3  can have a direction of view that is different from the direction of view of the first camera  121   a  shown in  FIG. 2 . In one embodiment, the first camera  121   a  can be rotatably coupled to the front case  100 A- 1  and can achieve the direction of view of the second camera  121   b . In such an embodiment, the second camera  121   b  can be optional. 
     The first and second cameras  121   a  and  121   b  can be configured to have different resolutions. In one embodiment, the first camera  121   a  can be configured to operate with a relatively lower resolution than the second camera  121   b . For example, the first camera  121   a  can be used to capture an image of the user to allow immediate transmission of the image during a video call and the second camera  121   b  can be used to capture images of general objects with high picture quality, which may not require immediate transmission in real-time, but may be stored for later viewing or use. 
     Additional camera related components, such as camera flash  125  and a mirror  126  can be disposed near the second camera  121   b . The mirror  126  allows self-image capturing by allowing the user to see himself when the user desires to capture his own image using the camera  121   b . The camera flash  125  can illuminate a subject when the second camera  121   b  captures an image of the subject. 
     A second audio output module (not shown in  FIG. 3 ) can be additionally provided in the second rear case  100 B- 2 . The second audio output module can support a stereo function along with the first audio output module  153   a . The second audio output module can also be used during a speaker-phone mode. 
     An antenna (not shown) for receiving a broadcast signal can be disposed on one side of the second rear case  100 B- 2 . The antenna can be extended and retracted from the second rear case  100 B- 2 . 
     As shown in  FIG. 3 , a slide module  100 C can be partially exposed on the first rear case  100 A- 2  of the first body  100 A. The slide module  100 C can be configured to couple the first body  100 A and the second body  100 B, such that the first body  100 A and the second body  100 B are allowed to slide up and down relative to one another. A portion of the slide module  100 C may be hidden from view by the second front case  100 B- 1  of the second body  100 B and, therefore, may not be exposed. 
     The second camera  121   b  and the other elements that have been described as being provided on the first rear case  100 A- 2  can be disposed on the first front case  100 A- 1 . 
     The power supply unit  190  can be disposed in the first rear case  100 A- 2 . The power supply unit  190  can be a rechargeable battery and can be detachably coupled to the first rear case  100 A- 2 . 
       FIG. 4  illustrates a diagram for explaining how to generate a proximity touch input in accordance with various embodiments of the invention. 
     As shown in  FIG. 4 , when a pointer  166 , such as a user&#39;s finger or stylus, approaches the display module  151 , the proximity sensor  141  located inside or near the display module  151  can detect the pointer  166  and provide a proximity signal. For example, the proximity sensor  141  can be configured to output a proximity signal indicating the distance between the pointer  166  and the display module  151 . Such a distance is also referred to in the art as a “proximity depth.” 
     The distance at which the proximity signal is provided by the proximity sensor  141  when the pointer  166  approaches the display module  151  is referred to as a detection distance. For example, the proximity depth can be determined by using a number of proximity sensors installed in the mobile terminal  100 , such as proximity sensor  141 , having various detection distances and by comparing the proximity signals provided by each corresponding proximity sensor. 
     In addition, it may be determined what part of the display module  151  is being approached by the pointer  166  and whether the pointer  166  is being moved within the proximity of the display module  151  by determining which of the number of proximity sensors  141  is providing a proximity signal. Then, the controller  180  can control the haptic module  157  to generate a haptic-effect signal corresponding to a touch key that is currently being approached by the pointer  166 . 
     The exemplary mobile terminal  100  shown in  FIG. 4  is configured to detect three proximity depths, such as proximity depths D 1 , D 2 , and D 3 , where each proximity depth represents the distance from the display module  151  to a location above the display module  151  in a substantially perpendicular direction above the display module  151 . The relationships between the proximity depths D 0 , D 1 , D 2 , and D 3  can be expressed as: D 0 &lt;D 1 &lt;D 2 &lt;D 3 . It should be understood that in other embodiments, the mobile terminal  100  can be configured to include less than or greater than three proximity sensors to enable detection of any number of proximity depths. 
     For example, when the pointer  166  comes into contact with the display module  151 , the proximity depth D 0  is detected and it is recognized as a typical touch input; when the pointer  166  is located within the proximity depth D 1  and the proximity depth D 0 , a proximity touch input at the proximity depth D 1  is recognized; when the pointer  166  is located between the proximity depth D 1  and the proximity depth D 2 , a proximity touch input at the proximity depth D 2  is recognized; when the pointer  166  is located within the proximity depth D 2  and the proximity depth D 3 , a proximity touch input at the proximity depth D 3  is recognized; when the pointer  166  is located at a distance greater than the proximity depth D 3 , no proximity touch is recognized. 
       FIGS. 5A and 5B  illustrate exemplary arrangements of haptic modules in the mobile terminal  100  in accordance with various embodiments of the invention. For example, as shown in  FIGS. 5A and 5B , the mobile terminal  100  can include a plurality of haptic modules, such as first haptic module  157   a  and second haptic module  157   b.    
     As shown in  FIG. 5A , for example, the first and second haptic modules  157   a  and  157   b  can be disposed at upper and lower sides of the display module  151 . Alternatively, referring to  FIG. 5B , the first and second haptic modules  157   a  and  157   b  can be disposed at left and right sides of the display module  151 . It should be understood that the arrangement of the haptic modules  157  shown in  FIGS. 5A and 5B  are merely illustrative and that various other arrangements of the haptic modules  157  can be achieved. For example, the mobile terminal  100  can include three or more haptic modules  157  disposed at the upper and lower sides of the display module  151  and at the left and right sides of the display module  151 . 
     The haptic modules  157 , such as haptic modules  157   a  and  157   b , can concurrently generate various haptic effects having different patterns, intensities or speeds. Alternatively, the mobile terminal  100  can be configured utilize only one haptic module  157  to concurrently generate various haptic effects. 
       FIG. 6  is a flowchart illustrating a method of controlling a mobile terminal in accordance with various embodiments of the invention. As shown in  FIG. 6 , an operating mode, such as a camera mode, a multimedia file play mode, or a broadcast-viewer mode is selected by the controller  180  (S 200 ). For example, the operating mode can be selected in response to a user command. The controller  180  then displays an operation screen corresponding to the selected operating mode on the display module  151  (S 205 ). 
     The controller  180  determines whether a user input of a first user input group is received (S 210 ). If a user input belonging to a first user input group is received (S 210 ), the controller  180  controls the first haptic module  157   a  to generate a first haptic effect corresponding to the first user input group (S 215 ) and performs an operation corresponding to the first user input group (S 220 ). 
     On the other hand, if the user input does not belong to the first user input group (S 210 ), the controller  180  determines whether a user input of a second user input group (S 225 ) is received. If a user input belonging to a second user input group is received (S 225 ), the controller  180  controls the second haptic module  157   b  to generate a second haptic effect corresponding to the second user input group (S 230 ) and performs an operation corresponding to the second user input group (S 235 ). If the user input does not belong to the second user input group (S 225 ), the controller  180  determines whether a different operating mode is selected (S 240 ). 
     If a different operating mode is selected (S 240 ), the method ends. However, if a different operating mode is not selected (S 240 ), the controller determines whether a user input of first user input group is received (S 210 ). Accordingly, operations S 210  through S 235  can be repeatedly performed until a different operating mode of the mobile terminal  100  is selected. 
     The first and second user input groups can vary according to the type of operating mode or user settings. For example, a user input for selecting a vowel can belong to the first user input group, and a user input for selecting a consonant can belong to the second user input group. Alternatively, a user input for selecting a lower case letter can belong to the first user input group and a user input for selecting a capital letter can belong to the second user input group. As another example, a user input can belong to one of the first and second user input groups according to the location of a letter that can be selected by the user input. 
     The first and second haptic effects can be generated at different locations of the mobile terminal  100 . In addition, the first and second haptic effects can have different patterns or intensities. The controller  180  can control the first and second haptic modules  157   a  and  157   b  to generate a third haptic effect for a certain type of event, where the third haptic effect can be a combination of the first and second haptic effects. 
     In this manner, it is possible to generate different haptic effects for different types of user inputs. 
       FIG. 7  is a flowchart illustrating a method of controlling a mobile terminal in accordance with various embodiments of the invention. Referring to  FIG. 7 , the controller  180  displays an operation screen corresponding to a current menu or operation selected by the user on the display module  151  (S 300 ). Examples of the operation screen include an idle screen, a still/moving image-viewer screen, a list screen, a broadcast screen, a map screen and a webpage screen. 
     The controller  180  then determines whether an event of a first event group has occurred (S 305 ). If an event belonging to a first event group has occurred (S 305 ), the controller  180  controls the first haptic module  157   a  to generate a first haptic effect corresponding to the first event group (S 310 ). On the other hand, if an event belonging to a first event group has not occurred (S 305 ), the controller determines whether an event of a second event group has occurred (S 315 ). 
     If an event belonging to the second event group has occurred (S 315 ), the controller  180  controls the second haptic module  157   b  to generate a second haptic effect corresponding to the second event group (S 320 ). If an event belonging to the second event group has not occurred (S 315 ), the controller  180  determines whether a user input, such as a touch input, has been received (S 325 ). If a user input has been received (S 325 ), the controller  180  performs an operation corresponding to the user input (S 330 ). If a user input has not been received (S 325 ), the controller  180  then determines whether another operating mode or menu has been selected (S 335 ). 
     If another operating mode or menu has been selected (S 335 ), the method ends. If another operating mode or menu has been selected (S 335 ), the controller  180  determines whether an event belonging to a first event group has occurred (S 305 ). Accordingly, operations S 305  through  5330  can be repeatedly performed until a different operating mode or menu is selected (S 335 ). 
     The first and second event groups can vary according to the types of operating modes or user settings. For example, an event that includes receiving a voice call can belong to the first event group and an event that includes receiving a video call can belong to the second event group. Alternatively, an event that includes receiving a short message service (SMS) message can belong to the first event group, and an event that includes receiving a multimedia messaging service (MMS) message can belong to the second event group. 
     The controller  180  can control the first and second haptic modules  157   a  and  157   b  to generate a third haptic effect, where the third haptic effect can be a combination of the first and second haptic effects, for a certain type of event. In this manner, it is possible to generate different haptic effects for different types of events. 
     The methods described above with respect to  FIGS. 6 and 7  will be described in further detail with reference to  FIGS. 8 through 22 . For convenience, it is assumed that the mobile terminal  100  generates a vibration as a haptic effect. However, it should be understood that the mobile terminal  100  can be configured to generate haptic effects other than a vibration. 
       FIGS. 8 through 18  are exemplary diagrams of the mobile terminal  100  performing the method described with respect to  FIG. 6 . 
       FIG. 8A  illustrates an exemplary character-input screen  400  displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 8A , if a typical touch input or proximity-touch input  403  for selecting a consonant letter is detected when the character input screen  400  is displayed, the first haptic module  157   a  disposed on the upper side of the display module  151  can generate a haptic effect. For example, a vibration  405  can be generated at the top of the character input screen  400 . 
       FIG. 8B  illustrates an exemplary character-input screen  410  displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 8B , if a typical touch input or proximity-touch input  413  for selecting a vowel is detected when the character-input screen  410  is displayed, the second haptic module  157   b  disposed on the lower side of the display module  151  can generate a haptic effect. For example, a vibration  407  can be generated at the bottom of the character input screen  400 . 
     Therefore, different haptic effects can be generated by the mobile terminal  100  depending on whether a consonant has been input or whether a vowel has been input. In addition, different haptic effects can be generated by the mobile terminal  100  depending on whether a lower case letter has been input or whether a capital letter has been input and different haptic effects can be generated by the mobile terminal  100  depending on whether a symbol has been input or whether an emoticon has been input. 
     Moreover, a haptic effect can be generated at different locations on the mobile terminal  100  for different rows of touch keys. For example, with reference to  FIG. 8B , if a touch key in a first row  412  or a second row  414  of a touch keypad is selected by a user, a haptic effect can be generated at the top of the character-input screen  410  of the display module  151 . On the other hand, if a touch key in a third row  416  or fourth row  418  of the touch keypad is selected by a user, a haptic effect can be generated at the bottom of the character-input screen  410  of the display module  151 . 
       FIGS. 9A and 9B  illustrate exemplary list screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 9A , if one of the listed items displayed on the list screen  420  is selected in response to a user input  423 , a first haptic effect, such as the vibration  406 , can be generated at the top of the list screen  420 . For example, with reference to  FIG. 9B , if a list of items displayed on the list screen  430  is scrolled through in response to a drag input  433 , a second haptic effect, such as the vibration  408 , can be generated for a short time at the bottom of the list screen  430 . 
     In one embodiment, if the items displayed on the list screen  430  are scrolled through to the extent that the top or the bottom of the list is encountered, a haptic effect that is a combination of the first and second haptic effects can be generated. Various haptic effects can also be generated in response to a flicking operation performed on the list screen  420  or  430 . 
       FIGS. 10A and 10B  illustrate exemplary screens for performing cell control displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 10A , if a user input  503  for selecting a previous item is received when the screen  500  is displayed, then a haptic effect, such as a vibration  409 , can be generated on the left side of the screen  500 . On the other hand, with reference to  FIG. 10B , if a user input  513  for selecting a subsequent item is received when the screen  510  is displayed, then a haptic effect, such as a vibration  411 , can be generated on the right side of the screen  510 . 
       FIGS. 11A and 11B  illustrate exemplary screens for playing an MP3 file or a moving image file in accordance with various embodiments of the invention. For example, with reference to  FIG. 11A , if a user input  525  for rewinding a moving image file currently being played is received when the screen  520  is displayed, then a haptic effect, such as a vibration  442 , can be generated on the left side of the screen  520 . On the other hand, with reference to  FIG. 11B , if a user input  533  for fast-forwarding a moving image file currently being played is received when the screen  530  is displayed, then a haptic effect, such as a vibration  444 , can be generated on the right side of the screen  530 . 
     For example, if a sectional repeat function is set, a haptic effect can be generated on the left side of the screen of the display module  151  at the beginning of the execution of the sectional repeat function, and a haptic effect can be generated on the right side of the screen of the display module  151  at the end of the execution of the sectional repeat function. 
       FIGS. 12A and 12B  illustrate exemplary image viewer screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 12A , an image  542  selected by the user can be displayed on the image viewer screen  540 . With reference to  FIG. 12B , if the image  542  displayed on the image viewer screen  550  is flicked or dragged, as indicated by reference numeral  553 , a complex haptic effect can be generated by combining a plurality of haptic effects in consideration of the speed and direction of the flicking or dragging of the image  542 . 
     If another image is selected, a complex haptic effect can also be generated by combining a plurality of haptic effects in order to alert the user. If a predetermined image is encountered during, for example, a slideshow, a complex haptic effect can also be generated by combining a plurality of haptic effects in order to alert the user. 
     As a further example, the dragging user input may include a velocity, such that responsive to dragging user input, a haptic feedback may be generated. This haptic feedback may occur at a plurality of locations and have an intensity which corresponds to the velocity of the dragging user input (e.g., increased velocity provides increased intensity and vice versa). Alternatively, the dragging user input may include a direction at which the input generally follows, such that responsive to the dragging user input, a haptic feedback may be generated. This haptic feedback may occur at a plurality of locations in a staggered manner that generally reflects the direction of the dragging user input (e.g., from left to right or bottom to top). 
       FIGS. 13A through 13C  illustrate exemplary editor screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, as shown in  FIG. 13A , if a “Content” section in the editor screen  600  is selected in response to a touch input, an editing page can gradually appear or disappear from the editor screen  600 , as shown in the editor screen  610  in  FIG. 13B . Furthermore, as shown in  FIG. 13C , a haptic effect, such as vibrations  445  and  447 , can be generated along a direction of the movement of the editor screen  620 . In addition, if a new screen is displayed over an existing page or if a new page gradually appears from the bottom of an existing page, then a haptic effect can also be generated. 
       FIGS. 14A and 14B  illustrate exemplary phonebook screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 14A , if a plurality of items displayed on the phonebook screen  630  are moved, deleted or copied, a complex haptic effect, such as a haptic effect including a combination of vibrations, e.g., “VIBRATION 1 ”  449  and “VIBRATION 2 ”  451 , can be generated as shown on the phonebook screen  640  in  FIG. 14B . 
       FIG. 15  illustrates an exemplary analog phone dial screen displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 15 , when the user dials each number of a phone number using the dial  657 , a haptic effect, such as one or more of vibrations  651 ,  653  and  655 , can be generated. In one embodiment, a different haptic effect can be generated for each different number dialed by the user. For instance, during operation, the terminal may receive a dragging user input initiating at a first location which generally corresponds to a selected one of the dial keys (e.g., one of 1-9 or 0) and extending in a generally counter-clockwise manner about a center-point defined by the dial keys. Next, responsive to each instance of the receiving of the dragging user input, a third haptic feedback at the mobile terminal may be generated such that the feedback may be repeated a number of times which correspond to the input number. These operations may be repeatedly performed to form a call number with the input numbers. 
     As still a further example, haptic feedback may be implemented to facilitate position location or directional applications such as GPS. For instance, the mobile terminal may display a map which represents a general location at which the mobile terminal is located. In this embodiment, a haptic feedback may be provided at one or more of a plurality of different locations of the mobile terminal (e.g., top, bottom, right, left, top-right, top-left, bottom-right, bottom-left, etc.) to reflect a suggested and corresponding change in travel direction along a suggested travel path. In general, each of the different locations correspond to a different direction of travel along the suggested travel path. For instance, if the directional application indicates that the user is to make a left turn, the haptic feedback will active on the left side of the terminal. Other turn indication may likewise be implemented using similar haptic feedback (e.g., right turns using right-side haptic feedback, etc.). 
       FIGS. 16A and 16B  illustrate exemplary thumbnail image screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 16A , if a user selects one of a plurality of thumbnail images displayed on the thumbnail image screen  660 , such as the thumbnail image  659 , then a first haptic effect, such as a vibration  665 , can be generated. Thereafter, if the selected thumbnail image is dragged and dropped over another thumbnail image via an input  663 , the first haptic effect and a second thumbnail image can be generated at substantially the same time. In addition, if one screen is laid over another screen, then two haptic effects respectively corresponding to the two screens, such as vibrations  665  and  667 , can be generated at substantially the same time. 
       FIGS. 17A and 17B  illustrate exemplary content search screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 17A , if the user chooses to open a parent folder, such as parent folder  686 , when the content search screen  680  is displayed, then a haptic effect, such as a vibration  682 , can be generated at the top of the content search screen  680 . On the other hand, with reference to  FIG. 17B , if the user chooses to open a sub-folder, such as subfolder  688 , when the content search screen  690  is displayed, then a haptic effect, such as a vibration  684 , can be generated at the bottom of the content search screen  690 . 
     If one of a plurality of files displayed on the content search screen  680  or  690  is selected, a complex haptic effect can be generated by combining a plurality of haptic effects according to whether the selected file is an image file, a moving image file or a file that cannot be executed. 
       FIGS. 18A and 18B  illustrate exemplary moving image play screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 18A , if an icon for fast-forwarding a moving image file currently being played is selected on screen  700 , then a haptic effect, such as a vibration  692 , can be generated. For example, with reference to  FIG. 18B , if an icon for fast-rewinding a moving image file currently being played is selected on screen  710 , then a haptic effect, such as a vibration  694 , can be generated. The haptic effect can be generated at different locations according to whether the selected icon corresponds to fast-forwarding or rewinding the moving image file currently being played. 
     In addition, if a plurality of notes are selected during a musical instrument-playing mode, a plurality of haptic effects respectively corresponding to the plurality of notes can be generated at substantially the same time. If one screen is replaced with another screen, a complex haptic effect can be generated by combining a plurality of haptic effects so as to provide a sensation similar to opening a zipper. If the mobile terminal  100  is released from a screen-lock state, various haptic effects can also be generated by combining a plurality of haptic effects. 
       FIGS. 19 through 22  illustrate exemplary diagrams for explaining the method described above with respect to  FIG. 7 . 
       FIGS. 19A through 19C  illustrate exemplary call reception screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 19A , a haptic effect, such as a vibration  732 , can be generated at the bottom of the call reception screen  720  during an incoming call from the caller identified as “BOSS.” As another example, with reference to  FIG. 19B , a haptic effect, such as a vibration  734 , can be generated at the top of the call reception screen  730  during an incoming call from the caller identified as “FRIEND.” As a further example, with reference to  FIG. 19C , multiple haptic effects, such as vibrations  736  and  738 , can be generated at the top and bottom of the call reception screen  740  during an incoming call from the caller identified as “RELATIVE.” 
     Accordingly, as described with respect to  FIGS. 19A through 19C , different haptic effects can be generated for different callers. The location or pattern of a haptic effect generated by the mobile terminal  100  can vary according to the biorhythm and emotional state of each caller. 
       FIGS. 20A and 20B  illustrate exemplary progress bar screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 20A , a directional haptic effect can be generated by combining a plurality of haptic effects, such as vibrations  551  and  555 , that can be generated on the left side and the center of the screen  550  of the display module  151 . As another example, with reference to  FIG. 20B , a directional haptic effect can be generated by combining a plurality of haptic effects, such as vibrations  557  and  559 , that can be generated on the right side and the center of the screen  560  of the display module  151 . In this manner, it is possible to alert the user with respect to the progress of an operation currently being performed by the controller  180 . The present invention can be directly applied to a progress bar displayed during a broadcast channel search/registration operation. 
       FIGS. 21A through 21C  illustrate exemplary call reception screens displayed by the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 21A , if a voice call is received during a predetermined operating mode, such as an MP3, FM radio, or digital multimedia broadcasting (DMB) radio mode, then a haptic effect, such as a vibration  782 , can be generated at the bottom of the screen  780  as shown in  FIG. 21B . As another example, with reference to  FIG. 21C , if a video call is received during a predetermined operating mode, such as an MP3, FM radio, or digital multimedia broadcasting (DMB) radio mode, then haptic effects, such as vibrations  792  and  794 , can be generated at the top and bottom of the screen  790  as shown in  FIG. 21C . If a call is received during a conference call or if two or more calls are merged, various haptic effects can be generated by combining a plurality of haptic effects. 
       FIGS. 22A and 22B  illustrate exemplary message reception screens displayed on the display module  151  in accordance with various embodiments of the invention. For example, with reference to  FIG. 22A , if a voice message is received by the mobile terminal  100 , then a haptic effect, such as a vibration  802 , can be generated. As another example, with reference to  FIG. 22B , if a Short Message Service (SMS) or a Multimedia Messaging Service (MMS) message is received by the mobile terminal  100 , then a haptic effect, such as vibrations  812  and  814 , can be generated. For example, the location and/or the pattern of the haptic effects described above can vary according to the type of the received message, such as whether the received message is an SMS message or an MMS message. 
     In this manner, a user of the mobile terminal  100  can easily differentiate an incoming voice call from an incoming video call, and can further differentiate an SMS message from an MMS message, based on the location and pattern of a haptic effect generated by the mobile terminal  100 . 
     Therefore, different haptic effects can be generated for different types of events. Moreover, various haptic effects can be generated upon the occurrence of various types of events, such as an alarm event or a scheduling event. 
     It should be understood that the mobile terminal  100  and the methods of controlling the mobile terminal  100  according to the exemplary embodiments described herein are not restricted to such exemplary embodiments. Therefore, variations and combinations of the exemplary embodiments described herein can fall within the scope of the invention. 
     The present invention can be realized as code that can be read by a processor (such as a mobile station modem (MSM)) included in a mobile terminal and that can be written on a computer-readable recording medium. The computer-readable recording medium can be any type of recording device in which data is stored in a computer-readable manner. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disc, an optical data storage, and a carrier wave (e.g., data transmission through the internet). The computer-readable recording medium can be distributed over a plurality of computer systems connected to a network so that computer-readable code is written thereto and executed therefrom in a decentralized manner. Functional programs, code, and code segments needed for realizing the present invention can be easily construed by one of ordinary skill in the art. 
     As described above, according to the present invention, it is possible to provide various haptic effects for different types of user inputs or events by using a plurality of haptic modules. Therefore, it is possible for a user to easily identify the type of user input or event not only with his or her sense of vision but also with his or her sense of touch. In addition, it is possible to provide various benefits such as entertainment and convenience and prevent the malfunction of a mobile terminal. 
     While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
