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 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.
The memory 160 may store a program for operations of the controller 180. The memory 160 may temporarily store input/output data (e.g., phonebook, message, still picture, moving picture, etc.).

An output window 151a may be displayed on a top portion of the display 151 and an input window 151b may be displayed on a bottom portion of the display 151. A soft key 151c representing a digit for inputting a phone number or the like may be output to the input window 151b. If the soft key 151c is touched, a digit corresponding to the touched soft key may be outputted to the output window 151a. If the first manipulating unit 131 is manipulated, a call connection for a phone number displayed on the output window 151a may be attempted.
FIG. 3B shows that an input touch may be applied to a soft key through a rear face of a terminal body. FIG. 3A shows that the terminal body is vertically arranged (i.e., in a portrait manner). FIG. 3B shows that the terminal body is horizontally arranged (i.e., in a landscape manner). The display 151 may change an output picture according to the arranged direction of the terminal body.
FIG. 3B also shows that a text input mode is activated in the mobile terminal 100. FIG. 3B shows that the touchscreen 135 may include an output window 135a and an input window 135b. The output window 135a and the input window 135b may be displayed on the display 151. A plurality of soft keys 135c representing characters, symbols and/or digits may be arranged in the input window 135b. The soft keys 135c may be arranged in a QWERTY key formation.
If the soft keys 135c are touched using the touchpad 135, the characters, symbols and/or digits corresponding to the touched soft keys may be outputted to the output window 135a. Touch input via the touchpad 135 may be advantageous in that the soft keys 135c may be prevented from being blocked by a finger in case of touch, which is compared to the touch input via the display 151. If the display 151 and the touchpad 135 are transparent, the mobile terminal 100 may visually check or determine whether fingers are located at the backside of the terminal body. Hence, more correct touch inputs may be made.
The display 151 and/or the touchpad 135 may receive a touch input by scrolling. A user may scroll the display 151 or the touchpad 135 to shift a cursor or pointer located at an entity (e.g., icon or the like) displayed on the display 151. If a finger is shifted on the display 151 or the touchpad 135, a path of the shifted finger may be visually displayed on the display 151. This may be useful in editing an image displayed on the display 151.
If both the display (touchscreen) 151 and the touchpad 135 are touched together within a predetermined amount of time, a particular function of the mobile terminal 100 can be executed. The simultaneous touch may correspond to a case that the terminal body is held by a user using a thumb and a first finger (clamping). The function may include activation or deactivation for the display 151 or the touchpad 135.
The proximity sensor 141 described with reference to FIG. 1 may now be explained in detail with reference to FIG. 4.
FIG. 4 is a diagram relating to a proximity depth of a proximity sensor. Other embodiments, arrangements and configurations may also be used.
As shown in FIG. 4, when a pointer, such as a user's finger, a pen, a stylus and the like, approaches the touchscreen, the proximity sensor 141 provided within or in a vicinity of the touchscreen may detect the approach of the pointer and then output a proximity signal.
The proximity sensor 141 may output a different proximity signal according to a distance between the pointer and the proximity-touched touchscreen (hereafter referred to as a proximity depth).
FIG. 4 shows a cross-section of the touchscreen provided with a proximity sensor capable of detecting three proximity depths, for example. A proximity sensor that identifies less than 3 proximity depths or more than 4 proximity depths may also be provided.
If the pointer fully contacts the touchscreen (d0), a contact touch may be recognized. If pointer is spaced apart from the touchscreen by a distance less than d1, a proximity touch to a first proximity depth may be recognized. If the pointer is spaced apart from the touchscreen by a distance between d1 and d2, a proximity touch to a second proximity depth may be recognized. If the pointer is spaced apart from the touchscreen in a distance less than d3 or equal to or greater than d2, a proximity touch to a third proximity depth may be recognized. If the pointer is spaced apart from the touchscreen in a distance equal to or greater than d3, a proximity touch is released.
The controller 180 may recognize the proximity touch as one of various input signals according to proximity depth and position of the pointer. The controller 180 may perform various operation controls according to various input signals.
FIG. 5 is a diagram for exampling a method of controlling a touch action when a pair of display units 155 and 156 overlap each other.
FIG. 5 shows a folder type mobile terminal in which a folder part is connected to a main body in a manner of being folded or unfolded. The mobile terminal shown in FIG. 5 includes a first display unit 155 and a second display unit 156.
The first display unit 155 provided on the folder part may be a light-transmittive or transparent type (such as TOLED), and the second display unit 156 provided on the main body may be a non-transmittive type (such as LCD). Each of the first display unit 155 and the second display unit 156 may include a touch-inputtable touchscreen.
For example, if a touch (i.e., a contact touch or a proximity touch) to the first display unit (or TOLED) 155 is detected, the controller 180 may select or run at least one image from an image list displayed on the first display unit 155 (or TOLED) according to a touch type and a touch duration.
A method may now be described of controlling information displayed on a different display unit than the second display unit 156 (or LCD) in case of a touch to the first display unit (or TOLED) 155 externally exposed in an overlapped configuration. The description may be made with reference to input types classified into a touch, a long touch, a long-touch & drag and/or etc.
In the overlapped state (a state that the mobile terminal is closed or folded), the first display unit (or TOLED) 155 may overlap with the second display unit (or LCD) 156. In this state, if a touch different from a touch for controlling an image displayed on the first display unit (or TOLED) 155, e.g., a long touch (e.g., a touch having a duration of at least 2 seconds) is detected, the controller 180 may enable at least one image to be selected from an image list displayed on the second display unit (or LCD) 156 according to the touched input. The result from running the selected image may be displayed on the first display unit (or TOLED) 155.
The long touch may be usable in selectively shifting a specific one of entities displayed on the second display unit (or LCD) 156 to the first display unit (or TOLED) 155 (without an action for running the corresponding entity). In particular, if a user performs a long touch on a prescribed region of the first display unit (or TOLED) 155 corresponding to a specific entity of the second display unit (or LCD) 156, the controller 180 may control the corresponding entity to be displayed by being shifted to the first display unit (or TOLED) 155.
An entity displayed on the first display unit (or TOLED) 155 may be displayed by being shifted to the second display unit (or LCD) 156 according to a prescribed touch input to the first display unit (or TOLED) 155 such as flicking, swirling and/or the like. FIG. 5 shows a menu displayed on the second display unit (or LCD) 156 is shifted to the first display unit (or TOLED) 155.
In case of another input (e.g., a drag is additionally detected together with a long touch), the controller 180 may execute a function associated with an image selected by the long touch so that a preview picture for the image may be displayed on the first display unit (or TOLED) 155, for example. FIG. 5 shows a preview (i.e., a picture of a male) for a menu (i.e., an image file) may be performed.
While the preview image is outputted, if a drag (or movement) toward a different image is additionally performed on the first display unit (or TOLED) 155 by maintaining the long touch, the controller 180 may shift a selection cursor (or a selection bar) of the second display unit (or LCD) 156 and then display the image selected by the selection cursor on the preview picture (i.e., a picture of a female). Thereafter, after completion of the touch (i.e., long touch and drag), the controller 180 may display the initial image selected by the long touch.
The touch action (long touch and drag) may be identically applied to a case that a slide (i.e., an action of a proximity touch corresponding to the drag) is detected together with a long proximity touch (e.g., a proximity touch maintained for at least 2 or 3 seconds) to the first display unit (or TOLED) 155.
If a touch action differing from the above-mentioned touch actions is detected, the controller 180 may operate in a same manner as the general touch controlling method.
The method of controlling the touch action in the overlapped state may be applicable to a terminal having a single display. The method of controlling the touch action in the overlapped state may also be applicable to terminals differing from the folder type terminal having a dual display.
FIGS. 6A and 6B are diagrams relating to a proximity touch recognition area and a tactile effect generation region.
FIG. 6A represents an object such as an icon, a menu item, etc. in a circle type for ease of description.
As shown in FIG. 6A(a), a region for displaying an object on the display 151 may be divided into a first region A at a central part and a second region B that encloses (or surrounds) the first region A. The first and second regions A and B may be configured to generate tactile effects, such as strength or pattern, that differ from each other. For example, the first and second regions A and B may be configured to generate 2-step vibrations in a manner of outputting a first vibration when the second region B is touched or outputting a second vibration greater than the first vibration when the first region A is touched.
If both the proximity touch recognition region and the haptic region are simultaneously set in the region having the object displayed therein, the haptic region may be set for generating the tactile effect that is different from the proximity touch recognition region for detecting the proximity signal. In particular, the haptic region may be narrower or wider than the proximity touch recognition region. For example, in FIG. 6A(a), the proximity touch recognition region may be set to the area including both the first and second regions A and B. The haptic region may be set to the first region A.
As shown in FIG. 6A(b), the region having the object displayed therein may be divided into three regions A, B and C. Alternatively, the region having the object displayed therein may be divided into N regions (N>4) as shown in FIG. 6A(c). Each of the divided regions may generate a tactile effect having a different strength or pattern. If a region having a single object represented therein is divided into at least three regions, the haptic region and the proximity touch recognition region may be set to differ from each other according to a use environment.
A size of the proximity touch recognition region of the display 151 may be set to vary according to proximity depth. For example, FIG. 6B(a) shows the proximity touch recognition region is configured to decrease by C→B→A according to the proximity depth for the display 151. The proximity touch recognition region may also be configured to increase by C→B→A according to the proximity depth for the display 151. The haptic region may be set to have a predetermined size, such as the region ‘H’ in FIG. 6B(b), regardless of the proximity depth for the display 151.
In case of dividing the object-displayed region for setting of the haptic region or the proximity touch recognition region, one of various schemes of horizontal/vertical division, radial division and/or combinations thereof may be used as well as the concentric circle type division shown in FIG. 6A.
Embodiments for a control method in the mobile terminal 100 may now be described with reference to the accompanying drawings. Embodiments may be used singly and/or by being combined together. Embodiments may be implemented more easily when the display 151 includes the touchscreen.
First Example Embodiment
According to a first example embodiment of the present invention, a calling terminal may simultaneously transmit a video call and a voice call to a called terminal. When a user of the calling terminal sends a call to the called terminal, the user may not need to select either a video call communication or a voice call communication.
An operating process of a calling terminal may be explained in detail with reference to FIGS. 7 and 8.
FIG. 7 is a flowchart of a method for providing a call of a calling terminal according to an example embodiment of the present invention. FIG. 8 is a diagram of a screen on which a processing setting a user-preferred call according to an example embodiment of the present invention. Other embodiments, configurations and arrangements are also within the scope of the present invention.
The controller 180 of a calling terminal may be in a standby mode in operation S71. If the mobile terminal 100 is in the standby mode, a determination may be made whether contact address information of a called terminal is selected via the input unit 130 or the touchscreen 151. If the contact information is selected in operation S72, then a message may be generated in operation S73 for carrying both a video call and a voice call to the selected contact address information. The generated message may be sent in operation S74. If the contact information is not selected in operation S72, the mobile terminal may remain in the standby mode.
The contact address information may include a name of a called user, a mobile phone number, a home address, a fax number, an e-mail address, a homepage address and/or etc.
The contact address information may be selected from a phonebook provided to the memory 160 or the contact address information may be inputted by a user.
The generated message may be a call connection setting message. The controller 180 may set a parameter value for making a request for the video call connection in a first bearer capability (hereafter ‘BC’) of the call connection setting message and may also set a parameter value for making a request for the voice call connection in a second BC.
The message generating process of the controller 180 may now be described. The contact address information selecting process of the calling terminal user and a method for setting a preferred call in the selected contact address information may be explained with reference to FIG. 8.
FIG. 8(a) shows that a contact address information list is displayed on a screen. A user may select contact address information 11 using the user input unit 130 or the touchscreen 151. FIG. 8(b) shows that a menu corresponding to the selected contact information may be displayed. FIG. 8(b) also shows selection of a user-preferred call scheme 12 for the selected contact address information 11. The controller 180 may then display a first window 13a and a second window 14b, as shown in FIG. 8(c), to select a preferred call scheme from the video call communication and the voice call communication.
If the user selects the first window 13a for the video call communication, the controller 180 may display a first identifier 13b within the selected contact address information 11, as shown in FIG. 8(d). The first identifier 13b may indicate that the preferred call scheme for the user is the video call scheme. The controller 180 may then set the preferred call scheme to the video call scheme within the contact address information 11.
If the user selects the second window 14a for the voice call communication, the controller 180 may display a second identifier 14b within the selected contact address information 11, as shown in FIG. 8(e). The second identifier 14b may indicate that the preferred call scheme for the user is the voice call scheme. The controller 180 may then set the preferred call scheme to the voice call scheme within the contact address information 11.
The controller 180 may check a video call connection count and a voice call connection count for the contact address information 11 for a predetermined amount of time. The controller 180 may then set the preferred call scheme to the call having a higher call connection count.
The generation of the message (operation S73) and the method for setting the preferred call scheme (FIG. 8) in the message may now be explained with reference to Tables 1 to 3.
Table 1 shows an example for a configuration of a call connection setting message for a general voice call transmission.

Referring to Table 1, ‘bc_repeat_ind_incl=0 (0x0)’ is an identifier that indicates whether a single BC or a plurality of BCs exist within the call connection setting message. Since Table 1 shows the call connection setting message for transmitting a voice call only, the single BC for the voice call transmission exists. Hence, the ‘bc_repeat_ind_incl’ is set to 0.
Additionally, ‘bearer_cap—1_incl=1’ and ‘bearer_cap—1’ are identifiers that indicate parameter values for the voice call connection are set within the first BC. Syntaxes below ‘bearer_cap—1’ are various parameter values for the voice call connection.
Finally, ‘bearer_cap—2_incl=0’ is an identifier that indicates that parameter values do not exist in the second BC.

Referring to Table 3, ‘bc_repeat_ind_incl=0 (0x0)’ is an identifier that indicates whether a single BC or a plurality of BCs exist within the call connection setting message. Since Table 3 shows the call connection setting message for transmitting a video call and a voice call simultaneously according to an example embodiment, the first BC for the video call transmission and the second BC for the voice call transmission both exist. Hence, the ‘bc_repeat_ind_incl’ is set to 1.
Additionally, ‘bearer_cap—1_incl=1’ and ‘bearer_cap—1’ are identifiers that indicate parameter values for the video call connection are set within the first BC. Syntaxes below ‘bearer_cap—1’ are various parameter values for the video call connection.
Finally, ‘bearer_cap—2_incl=1’ is an identifier that indicates that parameter values for the voice call connection are set within the second BC.
If the preferred call scheme of the user is the video call connection (as shown in FIG. 8(d)), the controller 180 may give a priority to the first BC, set the parameter values for the video call connection within the first BC, and set the parameter values for the voice call connection within the second BC. When the receiving side receives the message, the receiving side may recognize that the call scheme preferred by the caller is the video call set within the first BC.
If the preferred call scheme of the user is the voice call connection (as shown in FIG. 8(e)), the controller 180 may give a priority to the first BC, set the parameter values for the voice call connection within the first BC, and set the parameter values for the video call connection within the second BC. When the receiving side receives the message, the receiving side may recognize that the call scheme preferred by the caller is the voice call set within the first BC.
The controller 180 may control the wireless communication unit 110 so that the message created by the process shown in Table 3 may be transmitted, in operation S74 (FIG. 7), to the called terminal corresponding to the selected contact address information 11.
An operating process of a called terminal according to a second example embodiment of the present invention may now be explained in detail.
Second Example Embodiment
According to a second example embodiment of the present invention, a called terminal may be enabled to determine whether to perform a video call communication or a voice call communication with a calling terminal. An operating process of a called terminal may now be explained with reference to FIG. 9.
FIG. 9 is a flowchart of a method for providing a call of a called terminal according to an example embodiment of the present invention. Other embodiments, configurations and arrangements are also within the scope of the present invention.
The controller 180 of a called terminal may be in a standby mode in operation S91. If a call connection setting message is received from a calling terminal via the wireless communication unit 110 in operation S92, the controller 180 may check, in operation S93, whether both a video call and a voice call are included in the received call connection setting message.
The controller 180 may parse an identifier ‘bc_repeat_ind_incl’ from the call connection setting message.
If the ‘bc_repeat_ind_incl’ is set to 1, the controller 180 may recognize that both a first BC and a second BC exist within the received call connection setting message and the controller 180 may then parse parameters set within the first BC and the second BC.
By parsing the parameter values set within ‘bearer_cap—1_incl’ (first BC) and parameter values set within ‘bearer_cap—2_incl’ (second BC), the controller 180 may recognize that the video call is included in the first BC and may also recognize that the voice call is included in the second BC.
Thus, if it is determined in operation S94 that both the video call and the voice call are included within the call connection setting message, the controller 180 may display a first information 21 and a second information 22 on a screen of the display module in operation S95. The first information 21 may indicate that the video call has been received and the second information 22 may indicate that the voice call has been received.
If either the displayed first information 21 or the displayed second information 22 is selected in operation S96, the controller 180 may connect the selected call and then perform a call operation for the connected call in operation S97. An identifier 23 may be displayed to indicate that the first information is the call scheme preferred by the caller.
A method for displaying a presence of receptions of the video call and the voice call may be explained with reference to FIG. 10. FIG. 10 is a diagram of a screen showing a method for displaying a reception of a video call and a reception of a voice call according to an example embodiment of the present invention.
As shown in FIG. 10(a), if a video call is included in a first BC within the received message and a voice call is included in a second BC within the received message, and since the call included in the first BC is a call scheme preferred by a caller, the controller 180 may enable a user to select the first information 21 indicating that the video call has been received in a manner of displaying the first information 21 with priority rather than the second information 22 indicating that the voice call has been received.
As shown in FIG. 10(b), the controller 180 may display the first information 21 such that the first information 21 is discriminated from the second information 22 by adjusting a displayed size, a displayed color, a font size and/or the like of the first information 21. The controller 180 may enable the user of the called terminal to select the first information 21.
As shown in FIG. 10(c), the controller 180 may display the identifier 23 for indicating that the video call scheme is the call scheme preferred by the caller within the first information 21. The controller 180 may enable the user of the called terminal to select the first information 21.
The controller 180 may select the video call communication or the voice call communication using the motion detecting sensor 142, the brightness detecting sensor 143, the distance detecting sensor 144 and/or the heat detecting sensor 145. The controller 180 may perform switching between the video call communication and the voice call communication using the same.
FIG. 11 is a flowchart of a method for switching a video call and a voice call using a motion detecting sensor according to an example embodiment of the present invention. Other embodiments, configurations and arrangements are also within the scope of the present invention.
The first and second informations 21 and 22 may be displayed in operation S111. If a first motion for the terminal body is detected via the motion detecting sensor 142 in operation S112, the controller 180 may connect the video call in operation S113 by regarding that the first information 21 is selected. The controller 180 may then provide a call operation for the connected video call in operation S114.
The first motion may be motion that corresponds to an action for a user to perform a video call communication such as by grabbing the terminal body with fingers. Alternatively, the first motion may be motion set by a user in advance.
On the other hand, if the first motion is not detected in operation S112 and a second motion for the terminal body is detected via the motion detecting sensor 142 in operation S115, then the controller 180 may connect the voice call in operation S116 by regarding that the second information 22 is selected. The controller 180 may then provide a call operation for the connected voice call in operation S117.
The second motion may be motion that corresponds to an action for a user to perform a voice call communication such as by grabbing the terminal body with fingers. Alternatively, the second motion may be motion set by a user in advance.
If the first motion is detected in operation S118 via the motion detecting sensor 142 in the course of providing the video call communication (in operation S114), the controller 180 may switch the video call communication to the voice call communication in operation S119.
If the first motion is detected in operation S120 via the motion detecting sensor 142 in the course of performing the voice call communication (in operation S117), the controller 180 may switch the voice call communication to the video call communication in operation S121.
FIG. 12 is a flowchart of a method for switching a video call and a voice call using a brightness detecting sensor according to an example embodiment of the present invention. Other embodiments, configurations and arrangements are also within the scope of the present invention.
The first and second informations 21 and 22 may be displayed in operation S131. The controller 180 may measure and/or detect brightness of ambient light around the terminal body by controlling the brightness detecting sensor 143 in operation S132.
If the brightness measured via the brightness detecting sensor 143 is equal to or less than a reference in operation S133, the controller 180 may connect a voice call in operation S134 by regarding that the second information 22 is selected. The controller 180 may then provide a call communication operation in operation S135 for the connected voice call.
The reference may be a brightness value of a state that a video call communication is not available due to a dark environment around the mobile terminal.
If the ambient brightness of the terminal is equal to or less than the reference, the video call communication may not be possible (or may be impractical) due to the dark environment around the terminal. The controller 180 may directly provide the voice call communication to the user.
If the brightness measured via the brightness detecting sensor 143 is greater than the reference in operation S133, a current ambient brightness of the terminal may be suitable for the video call communication. Therefore, the controller 180 may connect a video call in operation S136 by regarding that the first information 21 is selected. The controller 180 may then provide a call communication operation in operation S137 for the connected video call.
If the brightness re-measured in the course of the voice call communication of the operation S137 via the brightness detecting sensor 143 is greater than the reference in operation S138, a current ambient brightness of the terminal may be suitable for the video call communication. Therefore, the controller 180 may switch the voice call communication to the video call communication in operation S139.
If the brightness re-measured in the course of the video call communication of the operation S137 via the brightness detecting sensor 143 is equal to or less than the reference in operation S140, a current ambient brightness of the terminal may not be suitable for the video call communication due to the current low brightness around the mobile terminal. Therefore, the controller 180 may switch the video call communication to the voice call communication in operation S141.
FIG. 13 is a flowchart of a method for switching a video call and a voice call using a distance detecting sensor according to an example embodiment of the present invention. Other embodiments, configurations and arrangements are also within the scope of the present invention.
The first and second informations 21 and 22 may be displayed in operation S151. The controller 180 may then measure in operation S152 a distance between a user and a terminal body using the distance detecting sensor 144.
If the distance measured via the distance detecting sensor 144 is equal to or less than a reference in operation S153, the controller 180 may connect a voice call in operation S154 by regarding that the second information 22 is selected. The controller 180 may then provide a call communication operation for the connected voice call in operation S155.
The reference may be a distance value suitable for the video call communication between the terminal body and the user.
When the distance between the terminal body and the user is equal to or less than the reference, this may be considered a state that an ear of the user is contacted with the audio output module 152 by holding the terminal body with fingers or may be considered a state that the video call communication is no possible (or is improbable) due to close distance between the user and the terminal. The controller 180 may provide the voice call communication to the user.
If the distance measured via the distance detecting sensor 144 exceeds the reference in operation S153, then a current distance between the terminal body and the user may be suitable for the video call communication. Therefore, the controller 180 may connect a video call in operation S156 by regarding that the first information 21 is selected. The controller 180 may then provide a call communication operation for the connected video call in operation S157.
If the distance re-measured in the course of the voice call communication (of operation S135) via the distance detecting sensor 144 is greater than the reference in operation S158, then a current distance between the terminal body and the user may be suitable for the video call communication. Therefore, the controller 180 may switch the voice call communication to the video call communication in operation S159.
If the distance re-measured in the course of the video call communication (of operation S157) via the distance detecting sensor 144 is equal to or less than the reference in operation S160, then a current distance between the terminal body and the user may not be possible (or may be improbable) for the video call communication. Therefore, the controller 180 may switch the video call communication to the voice call communication in operation S161.
FIG. 14 is a flowchart of a method for switching a video call and a voice call using a heat detecting sensor according to an example embodiment of the present invention. Other embodiments, configurations and arrangements are also within the scope of the present invention.
The first and second informations 21 and 22 may be displayed in operation S171. The controller 180 may measure a temperature of a user for the terminal body contact through the heat detecting sensor 145 in operation S172.
If the heat measured via the heat detecting sensor 145 is not equal to a reference in operation S173, then the controller 180 may connect a video call in operation S174 by regarding that the first information 21 is selected. The controller 180 may then provide a call communication operation for the connected video call in operation S175.
The reference may be a temperature value corresponding to a user's body temperature.
When the measured temperature is not equal to the reference, this may be considered a state that the user does not hold the terminal body with fingers. The voice call communication may not be possible (or may be improbable) while the terminal body is not held with fingers. Hence, the controller 180 may provide the video call communication to the user.
If the heat measured via the heat detecting sensor 145 is equal to the reference as determined in operation S173, then the user may currently hold the terminal body with fingers. The controller 180 may connect a voice call in operation 176 by regarding that the second information 22 is selected. The controller 180 may then provide a call communication operation for the connected voice call in operation S177.
If the heat re-measured in the course of the video call communication (of operation S175) via the heat detecting sensor 145 is equal to the reference in operation S178, then this may mean that the user may currently hold the terminal body with fingers. Therefore, the controller 180 may switch the video call communication to the voice call communication in operation S179.
If the heat re-measured in the course of the video call communication (of operation S175) via the heat detecting sensor 145 is not equal to the reference in operation S180, then the user may not currently hold the terminal body with fingers. Since the video call communication is suitable for the state that the user does not hold the terminal body with fingers, the controller 180 may switch the voice call communication to the video call communication in operation S181.
Embodiments of the present invention may provide effects and/or advantages.
Since a calling terminal transmits both a video call and a voice call to a called terminal, it may not be necessary to select either a video call communication or a voice call communication. Therefore, embodiments may enable the video call communication or the voice call communication to be connected using a single send key.
A called terminal may be enabled to determine whether to perform a video call communication or a voice call communication with a calling terminal, thereby providing a user of the called terminal with various call communication functions.
The above-described methods can be implemented in a program recorded medium as computer-readable codes. The computer-readable media may include all kinds of recording devices in which data readable by a computer system are stored. The computer-readable media include ROM, RAM, CD-ROM, magnetic tapes, floppy discs, optical data storage devices, and the like for example and also include carrier-wave type implementations (e.g., transmission via Internet).
