DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Hereinafter, exemplary embodiments will be described in greater detail with reference to the accompanying drawings.

In the following description, same reference numerals are used for the same elements when they are depicted in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in an understanding of exemplary embodiments. Thus, it is apparent that exemplary embodiments can be carried out without those specifically defined matters. Also, functions or elements known in the related art are not described in detail since they would obscure the exemplary embodiments with unnecessary detail.

FIG. 1is a schematic block diagram illustrating an electronic apparatus100according to an exemplary embodiment.

Referring toFIG. 1, the electronic apparatus100includes a voice input unit110, a motion input unit120, a storage unit130, and a control unit140. The electronic apparatus100may be realized by, but not limited to, a smart television (TV), a set-top box, a personal computer (PC), or a digital TV, which is connectable to an external network.

The voice input unit110receives input of a voice that is uttered by a user. The voice input unit110converts an input voice signal into an electric signal and outputs the electric signal to the control unit140. For example, the voice input unit110may be realized by a microphone. Also, the voice input unit110may realized by an internal component in the electronic apparatus100or an external device. The external device voice input unit110may be connected to the electronic apparatus100through a wired or wireless connection or through a network.

The motion input unit120receives an image signal (for example, a continuous frame) that is obtained by photographing a user motion and provides the image signal to the control unit140. For example, the motion input unit120may be realized by a unit including a lens and an image sensor. The motion input unit120may be realized by an internal component in the electronic apparatus100or an external device. The external device motion input unit120may be connected to the electronic apparatus100in a wired or wireless connection or over a network.

The storage unit130stores various data and programs for driving and controlling the electronic apparatus100. The storage unit130stores a voice recognition module that recognizes a voice input through the voice input unit110, and a motion recognition module that recognizes a motion input through the motion input unit120.

The storage unit130may include a voice database and a motion database. The voice database refers to a database on which a predetermined voice and a voice task matched with the predetermined voice are recorded. The motion database refers to a database on which a predetermined motion and a motion task matched with the predetermined motion are recorded.

The control unit140controls the voice input unit110, the motion input unit120, and the storage unit130. The control unit140may include a hardware processor such as a central processing unit (CPU), and a read only memory (ROM) and a random access memory (RAM) to store a module and data for controlling the electronic apparatus100.

If a voice is input through the voice input unit110, the control unit140recognizes the voice using the voice recognition module and the voice database. The voice recognition may be divided into isolated word recognition that recognizes an uttered voice by distinguishing words in accordance with a form of an input voice, continuous speech recognition that recognizes a continuous word, a continuous sentence, and a dialogic voice, and keyword spotting that is an intermediate type between the isolated word recognition and the continuous speech recognition and recognizes a voice by detecting a pre-defined keyword. If a user voice is input, the control unit140determines a voice section by detecting a beginning and an end of the voice uttered by the user from an input voice signal. The control unit140calculates energy of the input voice signal, classifies an energy level of the voice signal in accordance with the calculated energy, and detects the voice section through dynamic programming. The control unit140generates phoneme data by detecting a phoneme, which is the smallest unit of voice, from the voice signal within the detected voice section based on an acoustic model. The control unit140generates text information by applying a hidden Markov model (HMM) to the generated phoneme data. However, the above-described voice recognition method is merely an example and other voice recognition methods may be used. In the above-described method, the control unit140recognizes the user voice included in the voice signal.

If a motion is input through the motion input unit120, the control unit140recognizes the motion using the motion recognition module and the motion database. The motion recognition divides an image (for example, a continuous frame) corresponding to the user motion input through the motion input unit120into a background and a hand area (for example, spreading out fingers or clenching fist by cupping hand), and recognizes a continuous hand motion. If a user motion is input, the control unit140stores a received image on a frame basis and senses an object (for example, a user's hand) of the user motion using a stored frame. The control unit140detects the object by sensing at least one of a shape, color, and a motion of the object included in the frame. The control unit140may trace the motion of the object using locations of the object included in the plurality of frames.

The control unit140determines the motion in accordance with a shape and a motion of the traced object. For example, the control unit140determines the user motion using at least one of a change in the shape, a speed, a location, and a direction of the object. The user motion includes a grab motion of clenching one hand, a pointing move motion of moving a displayed cursor with one hand, a slap motion of moving one hand in one direction at a predetermined speed or higher, a shake motion of shaking one hand horizontally or vertically, and a rotation motion of rotating one hand. The technical idea of the present disclosure may be applied to other motions. For example, the user motion may further include a spread motion of spreading one hand.

The control unit140determines whether the object leaves a predetermined area (for example, a square of 40 cm×40 cm) within a predetermined time (for example, 800 ms) in order to determine whether the user motion is the point move motion or the slap motion. If the object does not leave the predetermined area within the predetermined time, the control unit140may determine that the user motion is a pointing move motion. If the object leaves the predetermined area within the predetermined time, the control unit140may determine that the user motion is a slap motion. As another example, if the speed of the object is lower than a predetermined speed (for example, 30 cm/s), the control unit140may determine that the user motion is a pointing move motion. If the speed of the object exceeds the predetermined speed, the control unit140determines that the user motion is a slap motion.

As described above, the control unit140performs a task of the electronic apparatus100using the recognized voice and motion. The task of the electronic apparatus includes at least one of functions performed by the electronic apparatus100, such as channel change, volume control, content replay (for example, a moving image, music or photo), or internet browsing.

The display unit193displays an image corresponding to a broadcast signal received through the broadcast receiving unit150. The display unit193may display image data (for example, a moving image) input through the external terminal input unit160or video stored in the storage unit. The display unit193may display voice assistance information for performing a voice task and motion assistance information for performing a motion task under control of the control unit140.

The control unit140performs a corresponding function by executing the software stored in the storage unit130.

Hereinafter, various exemplary embodiments will be explained with reference to the accompanying drawings.

If a user voice is recognized through the voice recognition module130k, the control unit140performs a voice task corresponding to the recognized user voice from among tasks that are controllable by a remote controller. If a user motion is recognized through the motion recognition module130l, the control unit140performs a motion task corresponding to the recognized user motion from among the tasks that are controllable by the remote controller. The voice task and the motion task may be mapped by being classified by buttons on the remote controller.

The voice task refers to a task that is controllable in accordance with a voice recognized through the voice recognition module. For example, the voice task may include at least one of functions of turning off the electronic apparatus100, channel shortcut, mute, changing an external terminal, setting a volume level, inputting texts, and reproducing/stopping an image. That is, various tasks having a name or an identifier that can be uttered by the user voice or a task requiring to input a text may be set as a voice task.

The motion task refers to a task that is controllable in accordance with a motion recognized through the motion recognition module. For example, the motion task may include channel changing, volume level control, screen navigation, slide bar control, and cursor pointing. That is, various tasks that can be controlled in phases in accordance with to a type and a direction of a user motion and a task using a cursor may be set as a motion task.

If a user voice is recognized through the voice recognition module, the control unit140performs a voice task directly corresponding to utterance included in the user voice.

For example, the control unit140recognizes a channel identifier from the voice uttered by the user. The channel identifier is to identify a channel and may include at least one of a channel name, a channel number, and a program name.

If a channel identifier is stored in the voice database stored in the storage unit130as described above, the control unit140performs a shortcut to a channel corresponding to the recognized channel identifier using the voice database. That is, if the user says “11”, the control unit140confirms whether a voice task corresponding to “11” is recorded on the voice database. If the voice task corresponding to “11” is a channel shortcut function to select channel 11, the control unit140performs the shortcut to channel 11.

If a user motion is recognized through the motion recognition module, the control unit140performs a motion task corresponding to the user motion in accordance with a direction of the user motion.

For example, if a slap motion in an upward direction is recognized through the motion recognition module, the control unit140may confirm a motion task corresponding to the slap motion in the upward direction from the motion database and may perform channel changing to change a current channel to a channel a number of which is increased by a predetermined number (for example, 1). If a slap motion in a downward direction is recognized through the motion recognition module, the control unit140may identify a motion task corresponding to the slap motion in the downward direction from the motion database and may perform channel changing to change a current channel to a channel a number of which is decreased by a predetermined number (for example, 1).

The voice tasks and the motion tasks may be mapped by being classified by buttons on a remote controller as shown inFIGS. 4 and 5.

FIG. 4illustrates buttons on a remote controller corresponding to a command to perform at least one voice task. That is, a task performed if a voice input is recognized may correspond to a task that is performed by one of the buttons on the remote controller. For example, a task that is performed by a power button401on the remote controller corresponds to a task that is performed if a voice “call word” (for example, “Ginny) or “power” is recognized. Accordingly, an external input button402corresponds to a voice “external input”. Also, a number button403corresponds to an uttered number. Also, a previous channel button404corresponds to a voice “previous channel”. A mute button405corresponds to a voice “mute” or “unmute.” Also, a channel list button406corresponds to a voice “channel list”. A smart hub/menu/search/quick menu/information display button407, a return button408, an exist button409, a social network/3D image providing button410, a help button411, and a replay/pause/stop/record button412correspond to voices corresponding to their respective names.

FIG. 5illustrates buttons on a remote controller corresponding to a motion to perform at least one motion task. That is, a task that is performed if a motion input is recognized may correspond to a task that is performed in accordance with one of the buttons on the remote controller. For example, as shown inFIG. 5, a task that is performed in accordance with a volume up/down button and a channel up/down button421corresponds to a task that is performed if slap motions in upward, downward, right, and leftward directions are recognized. Accordingly, upward, downward, leftward, and rightward directions buttons422correspond to slap motions in upward, downward, leftward, and rightward directions. A selection button423may correspond to a grab motion. A function button425may correspond to a pointing motion of a corresponding key if on screen display (OSD) includes a key guide.

The voice task and the motion task may change settings of the electronic apparatus100independently without being combined with each other. That is, the voice task may change the settings of the electronic apparatus100using a user voice recognized by the voice recognition module130k, and the motion task may change the settings of the electronic apparatus100using a user motion recognized by the motion recognition module130l.

The control unit140recognizes one of the user voice and the user motion through one of the voice recognition module130kand the motion recognition module130l. If a user voice is recognized through the voice recognition module130k, the control unit140executes a content having a content identifier corresponding to the recognized user voice from among a plurality of contents having content identifiers, respectively. If a user motion is recognized through the motion recognition module130l, the control unit140changes a plurality of contents in accordance with a direction of the user motion.

The content recited herein may be a broadcast content. In particular, if a user voice is recognized through the voice recognition module130k, the control unit140changes a current broadcast channel to a broadcast channel having a broadcast channel identifier corresponding to the recognized user voice from among a plurality of broadcast channels having broadcast channel identifiers, respectively. The channel identifier may include at least one of a channel number, a channel name, and a program name.

If a user motion is recognized through the motion recognition module130l, the control unit140changes a plurality of broadcast channels in phases in accordance with a direction of the user motion. The user motion may include a slap motion. For example, if the recognized user motion is a slap motion in an upward direction, the control unit140performs channel changing so that a current broadcast channel is changed to a broadcast channel a number of which is increased by a predetermined number. If the recognized user motion is a slap motion in a downward direction, the control unit140performs a channel changing so that a current broadcast channel is changed to a broadcast channel a number of which is decreased by a predetermined number.

The content may be one of an image content, a music content, and a photo content. If the content is one of the image content, the music content, and the photo content, the content identifier may be a name of the content.

If the content is one of the image content, the music content, and the photo content, the user motion may include a slap motion. For example, if the recognized user motion is a slap motion in a rightward direction, the control unit140may change a current content to a next content on a content list including a plurality of contents to be reproduced, and, if the recognized user motion is a slap motion in a leftward direction, the control unit140may change a current content to a previous content on the content list.

If a voice start command is recognized through the voice recognition module130k, the control unit140changes a mode of the electronic apparatus100to a voice task mode in which the electronic apparatus100is controlled in accordance with a user voice recognized through the voice recognition module130k. If a motion start command is recognized through the motion recognition module130l, the control unit140changes a mode of the electronic apparatus100to a motion task mode in which the electronic apparatus100is controlled in accordance with a user motion recognized through the motion recognition module130l.

Specifically, the control unit140may be operated in one of a remote control mode in which the electronic apparatus100is controlled by a remote controlling apparatus (for example, a remote controller), a voice task mode in which the electronic apparatus100is controlled in accordance with a voice, and a motion task mode in which the electronic apparatus100is controlled in accordance with a motion. If a command to start another mode is input, the control unit140may change a current mode to a corresponding mode.

If a voice start command (trigger voice) is recognized through the voice recognition module130kwhile the electronic apparatus100is in the remote control mode or the motion task mode, the control unit140changes a mode of the electronic apparatus100to the voice task mode. The voice start command is a command that includes a word matched with an operation of entering the voice task mode. For example, if a word “Ginny” is set as a voice start command, the control unit140changes a mode of the electronic apparatus100to the voice task mode when the word “Ginny” is recognized. The word regarding the voice start command may be directly changed by the user in a configuration mode of the electronic apparatus100or may be a fixed command that is defined as default at the manufacturing time of the electronic apparatus100.

In the voice task mode, the control unit140performs a voice task corresponding to a word included in the voice uttered by the user using the voice database.

The control unit140may maintain the voice task mode until a start command to return to the remote control mode, a mode canceling command, or a motion start command to change to a motion task mode is recognized. If no voice is recognized for a predetermined time (for example, 5 minutes) after the mode has been changed to the voice task mode, the control unit140may return to the remote control mode automatically.

If a motion start command (trigger motion) is recognized through the motion recognition module130lin the general mode or the voice task mode, the control unit140may change a current mode to the motion task mode. The motion start command is a pre-set motion to enter the motion task mode. For example, if a motion of shaking one hand horizontally 3˜4 times is set as a motion start command, the control unit140changes the mode to the motion task mode when such a motion is recognized. The motion regarding the motion start command may be directly changed by the user in a configuration mode or may be a fixed motion that is defined as default at the manufacturing time of the electronic apparatus100.

In the motion task mode, the control unit140performs a motion task corresponding to the user motion using the motion database. The control unit140may maintain the motion task mode until a start command to return to the remote control mode, a mode canceling command, or a voice start command to change to the voice task mode is recognized. If no motion is recognized for a predetermined time (for example, 5 minutes) after the mode has been changed to the motion task mode, the control unit140may return to the remote control mode automatically.

The control unit140displays one of voice assistance information including a voice item to guide voice recognition and motion assistance information including a motion item to guide motion recognition. If one of commands corresponding to the voice items included in the voice assistance information is recognized, the control unit140performs a voice task corresponding to the recognized command. If one of motions corresponding to the motion item included in the motion assistance information is recognized, the control unit140performs a motion task corresponding to the recognized motion.

Specifically, if a voice start command is recognized through the voice recognition module130k, the control unit140may control to display voice items regarding voice tasks that are controllable by the user voice. The voice items may display commands corresponding to the various voice tasks. Accordingly, if the user utters a certain command, the user can easily recognize which voice task will be performed and thus can perform the voice task more easily.

If a motion start command is recognized through the motion recognition module130l, the control unit140may control to display a motion item regarding motion tasks that are controllable by the user motion. The motion item may display motions corresponding to the various motion tasks. Accordingly, if the user performs a certain motion, the user can easily recognize which motion task will be performed and thus can perform the motion task more easily.

The voice item or the motion item may be displayed on the same area of a display screen (for example, a lower portion of the screen). The area on which the voice item or the motion item is displayed may be overlapped with a displayed image. However, this is merely an example and the voice item and the motion item may be displayed on other locations or in other methods. For example, the voice item or the motion item may be displayed on a right portion or a left portion of the display screen.

The voice assistance information may include a guide area810including the at least one voice item or a mode display area820displaying a designated mode (for example, the voice task mode or the motion task mode) of the electronic apparatus100. The mode display area820may include at least one of a mode image and a text indicating the designated mode of the voice task mode and the motion task mode. Also, the guide area810and the mode display area820may be distinctively displayed as shown inFIG. 61or may be displayed without drawing a boundary between the two areas. The mode display area820may be omitted. The location of each of the guide area810and the mode display area820may be set at the manufacturing time of the electronic apparatus100, or may arbitrarily set by the user, or the guide area810and the mode display area820may be dynamically located according to an image displayed along a UI. For example, if an OSD is displayed, the location of each of the guide area810and the mode display area820may be changed to a certain location out of an area where the OSD is displayed so that the display of the OSD is highlighted. The guide area810may be displayed on the lower portion of the display screen and the mode display area820may be displayed at a lower center of the display screen. Also, the location of the mode display area820may be changed to another location such as a lower right portion independently from the guide area810according to configuration.

In the voice task mode, the guide area810includes at least one voice items811,812,813,814,815,816,817, and818. For example, each of the at least one voice item may be a command to perform a voice task. At least one command included in the guide area810may include power off811, channel812, mute813, external input814, smart hub815, apps816, search817or all818. The power off811is a command to turn off the electronic apparatus100. The channel812is a command to perform channel shortcut. The mute813is a command to perform mute. The external input814is to command to change external input. The smart hub815is a command to perform a task of entering a smart function such as an Internet function, an application providing function, and a multimedia (for example, a moving image, music, and a photo) providing function of the electronic apparatus100. The apps816is a command to perform a task of searching an application of the electronic apparatus100. The search817is a command to perform a content, an application and web searching provided by the electronic apparatus100. The all818is a command to display all commands. The guide area818may include ‘more’ as a command instead of the all818. That is, the all818and ‘more’ may be voice items for displaying other items than the at least one voice items811,812,813,814,815,816,817, and818from among the voice items corresponding to the voice tasks. Also, if the electronic apparatus100displays other items, the electronic apparatus100may be configured not to use a pre-set timer. The pre-set timer is a timer to stop the voice task mode if at least one of the displayed voice items811,812,813,814,815,816,817, and818is not recognized for a pre-set time. If the voice task mode is stopped, the voice assistance information may disappear and the mode may be changed to a mode in which the electronic apparatus100is controlled by a general remote controller. Also, if the voice task mode is stopped, the performance of the voice task may be limited until the electronic apparatus100re-enters the voice task mode according to a voice start command. Also, if an OSD or a recognition candidate is displayed on the screen along with the voice assistance information, the motion assistance information, and additional item information, the pre-set timer to stop the designated mode may not be driven regardless of the designated mode. Also, the guide area810may include other commands than the above-described commands.

The at least one voice item811,812,813,814,815,816,817,818, which is displayed as the voice assistance information, may be differently configured according to a currently performed function. That is, the at least one command displayed on the guide area810may be differently configured according to a currently performed function. Specifically, at least one of the voice items corresponding to the voice tasks may be selectively configured according to at least one of an application, OSD, and a candidate displayed along with the voice assistance information. For example, if a smart function is currently performed in the electronic apparatus100, voice assistance information including a command “return” to return to a broadcast receiving function may be displayed. A recognition candidate may include at least one of a name having at least one of a number or a text similar to a recognized voice, a command similar to a recognized voice, a task corresponding to a similar command, a motion similar to a recognized motion, and a task corresponding to a similar motion. For example, candidates similar to a recognized voice may display a list of channel identifiers similar to the recognized voice in a pop-up window. The OSD may include current setting information of the electronic apparatus100and a setting menu of the electronic apparatus100excluding the recognition candidate. For example, as the OSD, an identifier of a current channel (a channel number or a channel name) may be displayed or an external input list or a channel list may be displayed.

The control unit140may recognize a first voice corresponding to a first voice item from among the at least one voice item811,812,813,814,815,816,817,818displayed as the voice assistance information. The control unit140may control to display additional item information regarding the first voice item corresponding to the recognized first voice. The additional item information regarding the first voice item may include an additional command regarding the first voice item, a guide message, or an utterance example. For example, if “channel” is recognized through the voice recognition module130kas a voice corresponding to the voice item812displayed on the guide area810and a task corresponding to the voice item812is channel shortcut, the display unit193may display additional item information including a guide message, an utterance example, or an additional command (for example, ‘previous’) for utterance of at least one identifier of a channel name, a program name, and a channel number, as shown inFIG. 62. The “previous” herein may be a command to display an UI including the guide area810ofFIG. 61again. The additional item information may include a guide area830including an additional command, a guide message, or an utterance example, and the mode display area820. For example, the guide message may be displayed on the left portion of the guide area830and the additional command or the utterance example may be displayed on the right portion of the guide area830.

The control unit140may recognize a second voice corresponding to the additional item information. The control unit140may perform a task corresponding to the first voice item and the second voice from among the voice tasks. For example, if the first voice item is the voice item812and “MBC” is recognized as the second voice corresponding to the additional item information ofFIG. 60, the control unit140may perform channel shortcut to change a current channel to a channel corresponding to the channel identifier including ‘MBC’. That is, the additional item information regarding the first voice item may be information for guiding utterance of the second voice to ask whether to perform the task corresponding to the first voice item or to additionally obtain information necessary for performing the task.

FIG. 63is a view illustrating motion assistance information displayed on the display unit193of the electronic apparatus100in the motion task mode according to an exemplary embodiment.

As shown inFIG. 63, the display unit193may display at least one motion item3311,3312,3313, and3314as the motion assistance information in the motion task mode. Each of the at least one motion item may include a motion image indicating a motion recognizable in the motion task mode or a text indicating a task corresponding to a recognizable motion (or a motion image). The motion assistance information may include a mode image or a text indicating the motion task mode. The motion assistance information may include a guide area3310including the at least one motion item and a mode display area3320displaying a mode of the electronic apparatus100. The mode display area3320may include at least one of a mode image and a text indicating a designated mode of the voice task mode and the motion task mode. The guide area3310and the mode display area3320may be distinctively displayed as shown inFIG. 63or may be displayed without drawing a boundary between the two areas. Also, the mode display area3320may be omitted. For example, the guide area3310may be displayed on the lower portion of the display screen and the mode display area3320may be displayed at a center of the lower portion of the display screen. The location of the mode display area3320may be changed according to configuration (for example, a right lower portion).

In the motion task mode, the guide area3310includes at least one motion item3311,3312,3313,3314. For example, each of the at least one motion item may include a motion image and a text indicating a task corresponding to the motion image. The at least one motion item included in the guide area3310may include a motion item3311indicating that a rotation motion in a counter clockwise direction corresponds to ‘back’ to go back to a previous setting, a motion item3312indicating that slap motions in upward/downward directions correspond to ‘volume up/down’ to control a volume level, a motion item3313indicating that slap motions in leftward/rightward directions correspond to ‘channel up/down’ to perform channel changing, and a motion item3314indicating that a grab motion corresponds to ‘replay’ to reproduce an image. The guide area3310may display other motion items than the above-described motion items. The motion image included in each of the above-described at least one motion item and the text corresponding to the motion image may be changed according to mapping settings between a recognizable motion and a task corresponding to the recognizable motion. For example, the guide area3310may include a motion item indicating that the slap motions in the upward/downward directions correspond to the channel up/down to perform the channel changing, and a motion item indicating that the slap motions in the leftward/rightward directions correspond to the volume up/down to control the volume level.

The at least one motion item3311,3312,3313,3314displayed as the motion assistance information may be differently configured according to a currently performed function. That is, the at least one motion item3311,3312,3314,3314displayed on the guide area3310may be differently configured according to a current function of the electronic apparatus100. For example, at least one of the motion items corresponding to the motion tasks may be selectively configured according to at least one of an application, OSD, and a recognition candidate displayed along with the motion assistance information.

The control unit140may recognize a first motion corresponding to a first motion item from among the at least one motion item3311,3312,3313,3314displayed as the motion assistance information. If additional item information exists, the control unit140may control to display additional item information regarding the first motion item corresponding to the recognized first motion. For example, if a grab motion corresponding to the motion item3314is recognized, additional item information including a guide message asking whether to reproduce a selected item or image file, or a motion item indicating that slap motions in leftward/rightward directions correspond to an answer Yes/No may be displayed.

The control unit140may recognize a second motion corresponding to the additional item information. The control unit140may perform a task corresponding to the first motion item and the recognized second motion from among the motion tasks. For example, if the first motion item is the motion item3314and a slap motion in a leftward direction is recognized as the second motion corresponding to the additional item information including a guide message asking whether to reproduce a designated image file and a motion item indicating that the slap motions in the leftward/rightward directions correspond to the answer Yes/No, the designated image file is reproduced. As described above, the additional item information regarding the first motion item may be information for guiding the second motion to ask whether to perform the task corresponding to the first motion item or to additionally obtain information necessary for performing the task.

If an error occurs in the motion recognition, motion assistance information indicating the error may be displayed. For example, the motion assistance information may include a guide message “Gesture has not been recognized. Please input again.” or a palm image that is mapped with a text indicating re-input. Also, the motion assistance information may include a guide message “Recognition of both hands is now impossible.” or a guide message “Available only in ‘Web Browser’, ‘View Photo’, and ‘Google Map App’”. The recognition of both hands may be performed to perform a task of enlarging a screen or reducing a screen, in response to a motion of moving both hands apart or pulling both hands closer to each other. Also, as part of the motion assistance information, an image or a text indicating an error may be displayed on the mode display area.

Hereinafter, a user interface (UI) for providing feedback in accordance with voice recognition or motion recognition of the electronic apparatus100will be explained with reference toFIGS. 64 to 66.

As shown inFIG. 64, the voice assistance information including the guide area810and the mode display area820may be displayed in the voice task mode. The guide area810and the mode display area820may be displayed with a visual effect that makes the guide area810and the mode display area820look like they rise from the lower end of the screen. For example, the guide area810and the mode display area820may be displayed in the form of animation for a predetermined time (for example, for 3 seconds). For example, a part of the guide area810and the mode display area820rises from the lower end rapidly and then rises slowly. The rising animation ends when the guide area810and the mode display area820are completely displayed as shown inFIG. 64. When the electronic apparatus100enters the motion task mode, the motion assistance information may be displayed in the form of animation described above. If a displayed UI of a specific mode disappears or if a mode is changed to a specific mode, various visual or auditory effects other than the above-described visual effect may be output.

If the electronic apparatus100recognizes the first voice corresponding to the first voice item, the electronic apparatus100may provide at least one of visual feedback and auditory feedback corresponding to a level of recognition accuracy in accordance with recognition accuracy of the first voice. If the electronic apparatus100recognizes the first motion corresponding to the first motion item, the electronic apparatus100may provide at least one of visual feedback and auditory feedback corresponding to a level of recognition accuracy in accordance with recognition accuracy of the first motion. The recognition accuracy herein may indicate a level based on which it is determined whether the first voice (or the first motion) is a voice (or a motion) recognizable by the electronic apparatus100, or may indicate a level based on which it is identified whether a recognized voice (or motion) corresponds to one of pre-set commands (or pre-set motions). The recognition accuracy may be an index changing according to how long it takes to identify a task corresponding to a recognized voice or motion.

For example, if “smart hub” is recognized as a voice corresponding to the voice item815, the electronic apparatus100may determine recognition accuracy by stochastically calculating the ability to identify the voice as one of the at least one command811,812,813,814,815,816,817,818included in the guide area810. The electronic apparatus100may compare the recognition accuracy and a pre-set threshold value and may differently display a visual effect according to whether the recognition accuracy is higher or lower than the pre-set threshold value. For example, as shown inFIG. 65, a rotating animation in a clockwise direction may be displayed on a background portion of an image in a mode display area6520indicating the voice task mode, according to the accuracy of voice recognition. If the recognition accuracy is lower than the threshold value, a rotation speed of the image of the animation is slow, and, if the recognition accuracy is higher than the threshold value, the rotation speed of the image is fast. When the above-described visual feedback is provided according to the recognition accuracy, auditory feedback may also be provided.

The animation, which is displayed on the mode display area820as the visual feedback, is displayed during a time period until a smart hub6600ofFIG. 66is driven and displayed after the voice corresponding to the voice item has been recognized, and may have nothing to do with the recognition accuracy.

If the electronic apparatus100recognizes the first voice corresponding to the first voice item, the electronic apparatus100may provide visual feedback or auditory feedback indicating at least one of the first voice item and the task corresponding to the first voice item. If the electronic apparatus100recognizes the first motion corresponding to the first motion item, the electronic apparatus100may provide visual feedback or auditory feedback indicating at least one of the first motion item and the task corresponding to the first motion item.

For example, if “smart hub” is recognized as a voice corresponding to the voice item815, “smart hub” may be displayed on a feedback area6530, indicating the voice item815or the task corresponding to the voice item815as shown inFIG. 65. The visual feedback may be displayed on a predetermined location of the screen without putting to a limit to the feedback area6530. Also, auditory feedback “You said, smart hub.” may be output along with the visual feedback displayed on the feedback area6530.

If a slap motion in a rightward direction is recognized as a motion corresponding to the item813, the electronic apparatus100may display visual feedback (for example, “You did, Channel UP”) indicating a task corresponding to one of the motion items on the feedback area6530, or may control to output auditory feedback using a text to speech (TTS) module (not shown) of the electronic apparatus100.

FIGS. 67 to 69are flowcharts to explain a controlling method of an electronic apparatus which provides voice assistance information and motion assistance information according to various exemplary embodiment.

FIG. 67is a flowchart to explain a controlling method of the electronic apparatus100according to an exemplary embodiment.

The electronic apparatus100may recognize a user input (a voice or a motion) using one of a voice recognition module or a motion recognition module (S6710). A user voice may input through a microphone and the input voice may be recognized by the voice recognition module, and a user motion may be photographed by a camera and the photographed motion may be recognized by the motion recognition module.

The electronic apparatus100may perform one of a voice task or a motion task in accordance with the received user input (S6720). That is, the electronic apparatus100may be operated in accordance with a designated mode of a voice task mode and a motion task mode. For example, if a voice start command or a motion start command is recognized, a mode corresponding to the recognized start command is designated.

The voice task mode is a mode in which at least one of first tasks (that is, voice tasks) is performed in accordance with a recognized voice, and the motion task mode is a mode in which at least one of second tasks (that is, motion tasks) is performed in accordance with a recognized motion. The voice tasks indicate tasks that are performed in accordance with a recognized voice, and the motion tasks indicate tasks that are performed in accordance with a recognized motion. The voice tasks and the motion tasks may be different from each other.

FIGS. 68 and 69are flowcharts illustrating a controlling method of the electronic apparatus100according to an exemplary embodiment.

The electronic apparatus100may identify which of the voice task mode and the motion task mode is designated (S6805). Although only the voice task mode or the motion task mode is displayed in the present exemplary embodiment, identifiable modes may further include a mode in which the electronic apparatus100is controlled by a remote controller. If the motion task mode is designated, the electronic apparatus100enters operation S6910ofFIG. 69and continues a controlling operation of the electronic apparatus100according to the present exemplary embodiment.

If the voice task mode is designated, the electronic apparatus100may display voice assistance information for performing the first tasks in the voice task mode in which at least one of the first tasks is performed in accordance with a recognized voice (S6810).

The electronic apparatus100may recognize a first voice corresponding to a first voice item from among at least one voice item displayed as the voice assistance information (S6815).

The electronic apparatus100may determine whether additional item information regarding the first voice item corresponding to the recognized first voice exists or not (S6820). If the additional item information regarding the first voice item does not exist, the electronic apparatus100may perform a task corresponding to the first voice item (S6825). Also, if the voice assistance information needs to be changed, the electronic apparatus100may display changed voice assistance information. For example, if mute is recognized as a voice corresponding to the voice item813, the electronic apparatus100performs mute, and changes the voice item813to the voice item2213and displays changed voice assistance information as shown inFIG. 22.

If the additional item information regarding the first voice item exists, the electronic apparatus100may display the additional item information regarding the first voice item corresponding to the recognized first voice (S6830). For example, if “channel” is recognized as a voice corresponding to the voice item, additional item information including a guide message or an utterance example may be displayed.

The electronic apparatus100may recognize a second voice corresponding to the additional item information (S6835).

The electronic apparatus100may perform a task corresponding to the first voice item and the recognized second voice from among the first tasks (S6840). For example, if the first voice item is the voice item812and the second voice is “seven”, the electronic apparatus100may perform channel shortcut to change a current channel to a channel having channel identifier7.

If the motion task mode is designated, the electronic apparatus100may display motion assistance information for performing the second tasks in the motion task mode in which at least one of the second tasks is performed in accordance with a recognized motion (S6910ofFIG. 69).

The electronic apparatus100may recognize a first motion corresponding to a first motion item from at least one motion item displayed as the motion assistance information (S6915).

The electronic apparatus100may determine whether additional item information regarding the first motion item corresponding to the recognized first motion exists or not (S6920). If the additional item information regarding the first motion item does not exist, the electronic apparatus100may perform a task corresponding to the first motion item (S6925). For example, if a slap motion in a rightward direction is recognized as a motion corresponding to the motion item3313inFIG. 33, the electronic apparatus100changes a current channel (channel 6) to a next channel (channel 7), which is located after the current channel (channel 6) according to a pre-set order, in accordance with channel-up. Also, if the motion assistance information needs to be changed, the electronic apparatus may display changed motion assistance information.

If the additional item information regarding the first motion item exists, the electronic apparatus100may display the additional item information regarding the first motion item corresponding to the recognized first motion (S6930). For example, if a grab motion corresponding to the motion item is recognized, the additional item information including a guide message asking whether to reproduce a selected item or image file or a motion item indicating that slap motions in leftward/rightward directions correspond to an answer Yes/No may be displayed.

The electronic apparatus100may recognize a second motion corresponding to the additional item information (S6935).

The electronic apparatus100may perform a task corresponding to the first motion item and the recognized second motion from among the second tasks (S6940). For example, if the first motion item is a motion item for reproducing an image and the second motion is a slap motion in a leftward direction, the electronic apparatus100may reproduce a designated image file.

The control unit140may distinctively display an executable icon of a content that is controllable through voice recognition and an executable icon of a content that is uncontrollable through voice recognition using the UI process module130j.

The control unit140may determine whether a content is supported by voice recognition using a header (not shown) of the content stored in the electronic apparatus100or a separate configuration file (not shown) included in the content.

If it is determined that the content is controllable through voice recognition, the control unit140combines an additional icon stored in the storage unit and an original executable icon of the content using the UI process module130j, and displays the combined icon. The user may know that the content is controllable through voice recognition based on the presence of the additional icon displayed on the display screen.

A plurality of additional icons may be stored in the storage unit130. The user may change an additional icon to be combined with the original executable icon through configuration.

Also, the control unit140may distinctively display a name of a content that is controllable through voice recognition and a name of a content that is uncontrollable through voice recognition using the UI process module130j, for example, by underlining and displaying the name in bold. The user may know that the content is controllable through voice recognition based on the name of the executable icon underlined and displayed in bold.

The control unit140may display an executable icon of a content that is controllable through voice recognition and a name of the executable icon distinctively from an executable icon of a content that is uncontrollable through voice recognition and a name of the executable icon using the UI process module130j.

The control unit140or the content may distinctively display a menu that is controllable through voice recognition and a menu that is uncontrollable through voice recognition from among menus of a tool bar displayed on a UI of the executed content (for example, menus ‘next’, ‘previous’, or ‘open’).

Hereinafter, a method for displaying an executable icon of an application that is controllable through voice recognition and a name of the executable icon distinctively from an executable icon of an application that is uncontrollable through voice recognition and a name of the executable icon according to various exemplary embodiments will be explained with reference toFIGS. 70 to 79.

FIGS. 92 and 93are flowcharts illustrating a controlling method of an electronic apparatus that changes a screen in response to a user motion according to various exemplary embodiments.

Referring toFIG. 92, the electronic apparatus100selects one broadcast signal from among a plurality of broadcast signals in response to a recognized user motion (S9212). The recognized user motion may be input through the motion input unit120and may be recognized by the motion recognition module130l. The electronic apparatus100provides the selected broadcast signal (S9214). The broadcast signal may be provided to the image output unit190or the display unit193. Then, in the event that the electronic apparatus100stops providing the selected broadcast signal and provides a stored content (S9216), the electronic apparatus100may re-recognize a user motion having the substantially same form as that of the recognized user motion (S9218). The stored content may be a content that is stored in the storage unit130or is received from the external terminal input unit160or the network interface180. The re-recognized user motion may be input through the motion input unit120and may be recognized by the motion recognition module130l. In response to the re-recognized user motion, the electronic apparatus100may change at least part of a screen where the provided content is displayed (S9220).

Referring toFIG. 93, the electronic apparatus100provides one of one broadcast signal from among a plurality of broadcast signals and a stored content (S9312). The electronic apparatus100recognizes a user motion through the motion recognition module130l(S9314). The electronic apparatus100may determine whether the provided signal is a broadcast signal or a content in response to the user motion (S9316). If the broadcast signal is provided, the electronic apparatus100may control a volume level of the broadcast signal or provide another broadcast signal from among the plurality of broadcast signals (S9318). If the content is provided, the electronic apparatus100changes at least part of a screen where the provided content is displayed (S9320).

As described above, the user can control the electronic apparatus100more efficiently and intuitively using the user motion.

The control unit140controls the electronic apparatus100in accordance with a remote control signal received from the remote control signal receiving unit170, a user voice input through the voice input unit110, and a user motion input through the motion input unit120. The remote controller recited herein may be a general remote controller, but this should not be considered as limiting. The remote controller may be a remote controller that includes a touch pad.

Specifically, if a voice start command input through the voice input unit110is recognized in a remote control mode, in which the electronic apparatus100is controlled in accordance with a remote control signal received at the remote control signal receiving unit170, the control unit140changes a mode to a voice task mode to perform a voice task that is controlled by a user voice input through the voice input unit110.

If the mode is changed to the voice task mode, the control unit140may control the display unit193to display an icon indicating that the mode of the electronic apparatus100is the voice task mode, and voice assistance information including a voice item guiding a voice task.

If a first button is selected from among buttons on the remote controller to change to the remote control mode in the voice task mode, the remote control signal receiving unit170receives a first remote control signal corresponding to the first button. The control unit140changes the mode of the electronic apparatus100to the remote control mode, in which the electronic apparatus100is controlled by the remote controller, in response to the first remote control signal. The first button may be a remote control mode change button to change the mode to the remote control mode. However, this is merely an example and the first button may be a certain button from among the buttons on the remote controller. If the first button is a certain button, the control unit140changes the mode to the remote control mode when receiving the first remote control signal corresponding to the first button, and then performs a task corresponding to the first button. For example, if the first button is a mute button, the control unit140changes the mode from the voice task mode to the remote control mode and then performs mute.

If a motion start command is input through the motion input unit120in the voice task mode, the control unit140recognizes the motion start command using the motion recognition module130l. If the motion start command is recognized, the control unit140changes the mode of the electronic apparatus100to a motion task mode in which the electronic apparatus100is controlled by a user motion input through the motion input unit120.

If the motion start command input through the motion input unit120is recognized in the remote control mode, in which the electronic apparatus100is controlled in accordance with a remote control signal received at the remote control signal receiving unit170, the control unit140changes the mode to the motion task mode to perform a motion task that is controlled by a user motion input through the motion input unit120.

If the mode is changed to the motion task mode, the control unit140may control the display unit193to display an icon indicating that the mode of the electronic apparatus100is the motion task mode, and motion assistance information including a motion item guiding a motion task.

If a first button is selected from among buttons on the remote controller to change to the remote control mode in the motion task mode, the remote control signal receiving unit170receives a first remote control signal corresponding to the first button. The control unit140changes the mode of the electronic apparatus100to the remote control mode in which the electronic apparatus100is controlled by the remote controller in response to the first remote control signal. The first button may be a remote control mode change button to change to the remote control mode. However, this is merely an example and the first button may be a certain button from among the buttons on the remote controller. If the first button is a certain button, the control unit140changes the mode to the remote control mode when receiving the first remote control signal corresponding to the first button, and then performs a task corresponding to the first button. For example, if the first button is a mute button, the control unit140changes the mode of the electronic apparatus100from the voice task mode to the remote control mode, and then performs mute.

If a voice start command is input through the voice input unit110in the motion task mode, the control unit140recognizes the voice start command using the voice recognition module130k. If the voice start command is recognized, the control unit140may change the mode of the electronic apparatus100to the voice task mode in which the electronic apparatus100is controlled in accordance with a user voice input through the voice input unit110.

Hereinafter, a method for changing to a remote control mode, a motion task mode, and a voice task mode according to an exemplary embodiment will be explained with reference toFIGS. 94 to 97.

Specifically, after the electronic apparatus100is turned on, the control unit140is generally operated in a remote control mode in which the electronic apparatus100is controlled by a remote control signal. In the remote control mode, a separate UI is not displayed as shown inFIG. 94. However, this is merely an example and the control unit140may display a UI indicating the remote control mode in the remote control mode.

If a voice start command is input through the voice input unit110in the remote control mode, the control unit140recognizes the voice start command and changes the mode of the electronic apparatus100to a voice task mode, in which the electronic apparatus100is controlled in accordance with a user voice input through the voice input unit110. When changing to the voice task mode, the control unit140may display voice assistance information as shown inFIG. 95.

If a first button on a remote controller is selected in the voice task mode, the control unit110receives a first remote control signal corresponding to the first button through the remote control signal receiving unit170, and changes the mode of the electronic apparatus100to the remote control mode again as shown inFIG. 94. The first button on the remote controller may be a remote control mode change button. However, this is merely an example and the first button may be a certain button on the remote controller.

If a motion start command is input through the motion input unit120in the voice task mode, the control unit140recognizes the motion start command and changes the mode of the electronic apparatus100to a motion task mode, in which the electronic apparatus100is controlled in accordance with a user motion input through the motion input unit120. When changing to the motion task mode, the control unit140may display motion assistance information3310as shown inFIG. 96.

If a motion start command is input through the motion input unit120in the remote control mode, the control unit140recognizes the motion start command and changes the mode of the electronic apparatus100to the motion task mode in which the electronic apparatus100is controlled in accordance with a user motion input through the motion input unit120. When changing to the motion task mode, the control unit140may display the motion assistance information3310as shown inFIG. 96.

If a first button on the remote controller is selected in the motion task mode, the control unit140receives a first remote control signal corresponding to the first button through the remote control signal receiving unit170and changes the mode of the electronic apparatus100to the remote control mode again as shown inFIG. 94. The first button on the remote controller may be a remote control mode change button. However, this is merely an example and the first button may be a certain button on the remote controller.

If a voice start command is input through the voice input unit110in the motion task mode, the control unit140recognizes the voice start command and changes the mode of the electronic apparatus100to the voice task mode in which the electronic apparatus is controlled in accordance with a user voice input through the voice input unit110. When changing to the voice task mode, the control unit140may display voice assistance information as shown inFIG. 95.

As described above, the electronic apparatus100may be changed to the remote control mode, the voice task mode, and the motion task mode using the remote control signal, the voice start command, and the motion start command, respectively.

FIG. 97is a flowchart to explain a method for changing to a remote control mode, a motion task mode, and a voice task mode according to an exemplary embodiment.

The electronic apparatus100is turned on and then enters a remote control mode in which the electronic apparatus100is controlled by a remote controller (S9710).

The electronic apparatus100remains in the remote control mode (S9710) unless a voice start command or a motion start command is input.

The electronic apparatus100determines whether or not a voice start command is input (S9720). If a voice start command is input (S9720-Y), the electronic apparatus100changes the mode of the electronic apparatus100to a voice task mode, in which the electronic apparatus100is controlled in accordance with a user voice input through the voice input unit110(S9730). When entering the voice task mode, the electronic apparatus100may display voice assistance information as shown inFIG. 95.

The electronic apparatus100determines whether or not a motion start command is input (S9740). If a motion start command is input in the voice task mode (S9740-Y), the electronic apparatus100changes the mode of the electronic apparatus100to a motion task mode, in which the electronic apparatus100is controlled in accordance with a user motion input through the motion input unit120(S9750).

If the electronic apparatus100is in either the voice task mode or the motion task mode, the control unit140determines whether or not to return to the remote control mode (S9760). As described above, the control unit140may return to the remote control mode if a start command to return to the remote control mode or a mode canceling command is recognized. Also, if the electronic apparatus100is in a voice task mode, the control unit140may automatically return to the remote control mode if no voice is recognized for a predetermined time (for example, 5 minutes). Similarly, if the electronic apparatus100is in a motion task mode, the control unit140may automatically return to the remote control mode if no motion is recognized for a predetermined time (for example, 5 minutes).

As shown inFIG. 97, the electronic apparatus100operates in the remote control mode (S9710), the voice task mode (S9730) and the motion task mode (S9750). In all three modes, the control unit140determines whether to switch to the voice task mode (S9720-Y), whether to switch to the motion task mode (S9740-Y), whether to switch to the remote control mode (S9760-Y) or whether to remain in the current mode (S9720-N, S9740-N, S9760-N). Although the method inFIG. 97has been described, this is merely an example and the technical idea of the present disclosure may be applied to any method for changing from/to the remote control mode, the voice task mode, and the motion task mode.

As described above, the mode of the electronic apparatus100is changed to the remote control mode, the voice task mode, and the motion task mode so that the user can control the electronic apparatus100according to a mode desired by the user.

The control unit140may control the electronic apparatus100through voice recognition using an external mobile device.

Specifically, if a user voice is input through a microphone included in an external mobile device, the control unit140receives input of the user voice through the voice input unit110, recognizes the input user voice, and performs a voice task of the electronic apparatus100in accordance with the recognized user voice. The mobile device may be, but not limited to, a remote controller, a mobile phone, a personal digital assistant (PDA), and a notebook computer. The voice input unit110may be a communication unit for receiving a user voice signal from the external mobile device.

An application for voice recognition is executed in the external mobile device and a user voice is input. If the mobile device recognizes the user voice, generates a control signal corresponding to the user voice, and then transmits the control signal to the electronic apparatus100, the control unit140may perform a voice task of the electronic apparatus100in accordance with the control signal input from the mobile device.

If an application for voice recognition is executed in the mobile device and a user voice input to the microphone included in the mobile device is input, the control unit140recognizes the input user voice and performs a voice task of the electronic apparatus100in accordance with the user voice.

If a first button included in the mobile device is selected after the application for voice recognition has been executed in the mobile device, the control unit140receives a first signal corresponding to the first button through a communication unit (not shown) and changes a mode of the electronic apparatus100to a voice task mode in response to the first signal. The voice task mode that is changed by selecting the first button included in the mobile device is a mode in which a voice task is performed in accordance with a user voice input from the microphone included in the mobile device. The voice task mode which is changed by selecting the first button included in the mobile device may be released if one of the first button and a second button on the mobile device is selected. The first button and the second button may be a physical button included in the mobile device. However, this is merely an example and the first button and the second button may be a UI that is displayed on the mobile device after the application for voice recognition has been executed.

The control unit140may receive input of a user voice from the mobile device, while the second button on the mobile device is selected in the voice task mode. The control unit140may display a UI indicating that a user voice can be input on the mobile device, while the second button on the mobile device is selected. Accordingly, the user may know that it is possible to input a voice through the UI displayed on the mobile device.

If a user voice is input to the mobile device, the control unit140does not receive a user voice through a microphone included in the electronic apparatus100.

The microphone included in the mobile device may be used when the mobile device makes a telephone call. That is, if the mobile device performs a general telephone call function, the microphone receives input of a voice for a telephone call from the user. If the mobile device executes an application for voice recognition, the mobile device may receive input of a voice to control the electronic apparatus100from the user.

FIG. 98is a flowchart to explain a method for recognizing a user voice using an external mobile device according to an exemplary embodiment.

The mobile device executes an application for voice input (S9810). The mobile device may be a mobile phone.

After the application for the voice input has been executed in the mobile device, the mobile device receives input of a user voice through a microphone included in the mobile device (S9820). The microphone included in the mobile device may be a microphone for making a telephone call.

The electronic apparatus100receives the user voice input to the external mobile device from the mobile device (9830).

If the user voice is received from the mobile device, the electronic apparatus100recognizes the user voice using the voice recognition module130k(S9840).

The electronic apparatus100performs a voice task in accordance with the recognized user voice using the voice database (S9850).

In the above exemplary embodiment, the mobile device receives the input of the user voice and transmits the user voice to the electronic apparatus100. However, this is merely an example and the mobile device may directly recognize the user voice, may generate a control signal corresponding to the user voice, and then may transmit the control signal to the electronic apparatus100.

As described above, the voice task of the electronic apparatus100is performed using the mobile device such as a mobile phone so that the user can control the electronic apparatus more easily using voice recognition.

According to an exemplary embodiment, the motion task mode may be one of a motion mode and a pointing mode according to whether a pointer is needed to perform a task. Specifically, the motion mode is a mode in which a task to change settings of the electronic apparatus100is controlled in accordance with a pre-set motion (for example, a slap motion in an upward, downward, leftward or rightward direction, a grab motion, or a rotation motion in a counter clockwise direction). For example, if a motion start command is input while the electronic apparatus100performs a broadcast receiving function, the control unit140may change a mode of the electronic apparatus100to the motion mode. Accordingly, the electronic apparatus100may perform a task such as volume control or channel change in response to a user motion matched with a pre-set motion.

The pointing mode is a mode in which a pointer is used to perform a task. For example, if a motion start command is input when the electronic apparatus100displays one of lists including a plurality of selectable items (for example, a content list, a channel list, an electronic program guide or EPG, and a web page), the control unit140may change a mode of the electronic apparatus100to the pointing mode. In the pointing mode, the control unit140displays a pointer at a center of a display screen. The pointer may be displayed at an upper position of the center of the display screen due to the presence of motion assistance information.

Hereinafter, the pointing mode will be explained in more detail.

If a motion start command is input through the motion input unit120while the electronic apparatus100displays one of a content list including a plurality of executable icons for executing applications (for example, a smart hub) and a web page, the control unit140changes a mode of the electronic apparatus100to a pointing mode and displays a pointer at a center of the display screen.

In the pointing mode, the electronic apparatus100may display motion assistance information for performing a motion task on a lower portion of the display screen. The displayed motion assistance information may be different from motion assistance information of the motion mode.

If a motion start command is input through the motion input unit120while the electronic apparatus100displays a content list, the control unit140changes a mode of the electronic apparatus100to a pointing mode. In the pointing mode, if the pointer is located at a first executable icon of the content list according to a user motion input to the motion input unit120, the control unit140displays the first executable icon distinctively from other executable icons. If a command to end a screen of the content list is input in the pointing mode, the control unit140may remove not only the content list but also the pointer from the display screen.

If a motion start command is input through the motion input unit120while the electronic apparatus100displays a web page, the control unit140changes a mode of the electronic apparatus100to a pointing mode. The web page may include a plurality of hyperlinks. In the pointing mode, if the pointer is located at a first hyperlink of the web page according to a user motion input through the motion input unit120, the control unit140displays the first hyperlink distinctively from other hyperlinks. If the pointer is located at the first hyperlink and a first user motion (for example, a grab motion) is input through the motion input unit120, the control unit140executes the first hyperlink.

Hereinafter, the pointing mode will be explained in more detail with reference toFIGS. 99 to 103.

If a content list including executable icons for executing applications is displayed as shown inFIG. 99and a motion start command is input through the motion input unit120, the control unit140may display motion assistance information and a pointer10010as shown inFIG. 100. The pointer10010may be displayed at a center of a display screen.

If a moving motion in a left-downward direction is input through the motion input unit120to place the pointer10010at executable icon “APP2”, the control unit140places the pointer10010at executable icon “APP2”. If the pointer10010is located at executable icon “APP2”, the control unit140highlights executable icon “APP2” and a name of the executable icon thicker than other icons as shown inFIG. 101.

If the pointer10010is located at executable icon “APP2” and a first user motion (for example, a grab motion) is input through the motion input unit120, the control unit120executes executable icon “APP2” as shown inFIG. 102.

If the content list is displayed and a content list release command (for example, a rotation motion in a counter clockwise direction or a button of a remote controller) is input from the user as shown inFIG. 100, the control unit140removes the content list and the pointer from the display screen and displays a broadcast receiving screen as shown inFIG. 103.

Although the content list is displayed in the above exemplary embodiment, the technical idea of the present disclosure may be applied if a web page including a plurality of hyperlinks is displayed.

FIG. 104is a flowchart to explain a method for providing a pointing mode according to an exemplary embodiment.

The electronic apparatus100displays one of a content list and a web page (S10410). The content list may include a plurality of executable icons for executing applications and the web page may include a plurality of hyperlinks.

The electronic apparatus100determines whether a motion start command is input or not (S10420).

If a motion start command is input (S10420-Y), the electronic apparatus100changes a mode of the electronic apparatus100to a pointing mode (S10430). The pointing mode is a mode to perform a task requiring a pointer (for example, executing an application and surfing a web page).

If the mode is changed to the pointing mode, the electronic apparatus100displays a pointer on a display screen (S10440). The pointer may be displayed at a center of the display screen.

As described above, the electronic apparatus100is changed to the pointing mode to perform a task requiring a pointer so that the user can control the electronic apparatus100more easily.

If a first motion is input through the motion input unit120in the pointing mode, the control unit140moves a pointer in a direction corresponding to the first motion, and, if a second motion is input through the motion input unit120, the control unit140performs a motion task corresponding the second motion.

If the second motion is input when the pointer is located at a first executable icon of the content list or at a first hyperlink of the web page, the control unit140may un-highlight the first executable icon and the first hyperlink at which the pointer is located.

The second motion may be a motion that is pre-set to perform a motion mode of the electronic apparatus100and may be one of a slap motion in an upward, downward, leftward or rightward direction, a grab motion, and a rotation motion in a counter clockwise direction.

For example, if the second motion is a slap motion in an upward, downward, leftward or rightward direction, the control unit140may move the display screen in accordance with the slap motion in the upward, downward, leftward, or rightward direction. After moving the screen, the control unit140may display the pointer at a prior location again.

Also, if the second motion is a grab motion, the control unit140may execute the first executable icon at which the pointer is located. After executing the first executable icon, the control unit140may display the pointer at the prior location again.

Also, if the second motion is a rotation motion in a counter clockwise direction, the control unit140may display a broadcast program of a currently tuned channel on the display screen. That is, the control unit140may remove the content list or the web page from the display screen and provide a broadcast receiving function. At this time, since the broadcast receiving function does not require a pointer, the pointer is not displayed.

Although the pointer is not displayed in the above example, this is merely an example. The pointer may be maintained at the location where the pointer has been displayed.

Hereinafter, a case in which a pre-set motion is input in a pointing mode will be explained in detail with reference toFIGS. 105 to 107.

If a mode of the electronic apparatus100is changed to a pointing mode as shown inFIG. 100, the control unit140displays a pointer10510at a center of the display screen as shown inFIG. 105.

If a slap motion in a rightward direction is input through the motion input unit120in the state where the pointer is displayed on the display screen, the control unit140removes the pointer10510from the display screen and changes a screen of an application display area1520to a screen of another application display area10530as shown inFIG. 106.

After moving the application display area10520, the control unit140displays the pointer10510again as shown inFIG. 107.

FIG. 108is a flowchart to explain a controlling method of the electronic apparatus100if a pre-set motion is input in a pointing mode according to an exemplary embodiment.

The electronic apparatus100displays one of a content list and a web page (S10810). The content list may include a plurality of executable icons for executing applications and the web page may include a plurality of hyperlinks.

The electronic apparatus100determines whether a motion start command is input or not (S10820).

If a motion start command is input (S10820-Y), the electronic apparatus100changes a mode of the electronic apparatus100to a pointing mode (S10830). The pointing mode is a mode to perform a task requiring a pointer (for example, executing an application and surfing a web page).

If the mode is changed to the pointing mode, the electronic apparatus100displays a pointer on the display screen (S10840). The pointer may be located at a center of the display screen.

If a pre-set motion is input through the motion input unit120in the state where the pointer is displayed (S10850-Y), the electronic apparatus100removes the pointer and performs a motion task corresponding to the pre-set motion (S10860). The pre-set motion is a motion that is pre-set in a motion mode and may be a slap motion in an upward, downward, leftward, or rightward direction, a grab motion, or a rotation mode in a counter clockwise direction.

The electronic apparatus100is controlled as described above so that the user can perform the task in accordance with the pre-set motion even in the pointing mode.

The control unit140may display a selected item distinctively from other items in accordance with a mode of the electronic apparatus100.

Specifically, the control unit140controls the display unit193to display a plurality of selectable items. The selectable item may be an executable icon of a content list or a hyperlink of a web page.

If one of a user voice and a user motion is input through one of the voice input unit110and the motion input unit120, the control unit140selects a first item from among the plurality of items in accordance with the user input. The control unit140may display the selected first item distinctively from other items. For example, the control unit140may highlight the selected first item thicker than other items.

If a name of the first item has a number of characters which exceeds a pre-set number and a mode of the electronic apparatus100is a motion task mode when the first item is displayed distinctively from other items, the control unit140may display the entire name of the first item. For example, the entire name of a selected executable icon, “Exciting Drum”, is displayed as shown inFIG. 109. The control unit140may display the entire name of the first item in a scrolling method. In the above example, the entire name of the item is displayed in the motion task mode. However, this is merely an example and the entire name of the item may be displayed even in a remote control mode.

On the other hand, if a name of the first item has a number of characters which exceeds a pre-set number and a mode of the electronic apparatus100is a voice task mode, the control unit140may display only a part of the name of the first item. The part of the name of the first item is fixed. For example, only a part of the name of the selected executable icon, “Exciting Drum” is displayed as shown inFIG. 110.

If only a part of the name of the first item is displayed in the voice task mode and a user voice input through the voice input unit110is consistent with the displayed part of the name, the control unit140executes the first item.

If there is no space in a part of the name of the displayed first item and a user voice corresponding a plurality of spellings of the name of the displayed first item is input through the voice input unit110, the control unit140executes the first item. For example, if the name of the displayed first item is “man” and voices “m”, “a”, and “n” are input in sequence, the control unit140executes the first item.

If a mode of the electronic apparatus100is a voice task mode and a plurality of items having names which are consistent with a user voice input through the voice input unit110are included among the names of the displayed items, the control unit140may display a list of a candidate group including the plurality of items. If the list of the candidate group is displayed, the control unit140may display the entire names of the items so that the user can clearly distinguish the items.

FIG. 111is a flowchart to explain a controlling method of the electronic apparatus100which displays items differently in accordance with a mode according to an exemplary embodiment.

The electronic apparatus100displays a plurality of selectable items (S11110). The plurality of items may be executable icons included in a content list for executing applications or hyperlinks included in a web page.

The electronic apparatus100receives input of one of a user voice and a user motion through one of the motion input unit110and the motion input unit120(S11120).

The electronic apparatus100selects a first item in accordance with a user input (S11130). For example, in a voice task mode, the electronic apparatus100may select the first item in accordance with a user voice input through the voice input unit110, and, in a motion task mode, the electronic apparatus100may select the first item in accordance with a user motion input through the motion input unit120. In a remote control mode, the electronic apparatus100may select the first item in accordance with a remote control signal input through the remote control signal receiving unit170.

If the first item is selected, the electronic apparatus100displays the selected first item distinctively from other items (S11140). For example, the electronic apparatus100may highlight the selected first item thicker than other items.

If a name of the first item has a number of characters which exceeds a pre-set number and a mode of the electronic apparatus100is the motion task mode (or the remote control mode) when the first item is displayed distinctively from other items, the electronic apparatus100may display the entire name of the first item. For example, as shown inFIG. 109, the entire name of a selected executable icon, “Exciting Drum”, is displayed. Also, the electronic apparatus100may display the entire name of the first item in a scrolling method.

On the other hand, if a name of the first item has a number of characters which exceeds a pre-set number and the mode of the electronic apparatus100is the voice task mode, the electronic apparatus100may display only a part of the name of the first item. The part of the name of the first item is fixed. For example, only a part (“Exciting”) of the name of the executable icon, “Exciting Drum”, is displayed as shown inFIG. 110.

As described above, only the part of the name of the item is displayed in the voice task mode, so that the user can execute the first item by uttering only the part of the name.

The control unit140displays voice assistance information including a plurality of voice items in the voice task mode. The voice assistance information includes an icon indicating that the mode of the electronic apparatus100is the voice task mode, and the icon indicating the voice task mode may be located at a center of the voice assistance information.

If the voice assistance information is displayed and a user voice corresponding to one of the plurality of voice items is input through the voice input unit110, the control unit140displays a guide message to perform a voice task on a first area of the voice assistance information, and displays the voice item on a second area of the voice assistance information. The first area may be a left area of the icon and the second area may be a right area of the icon. An output property of the guide message may be different from an output property of the voice item. The output property may include at least one of size, chroma, brightness, and color of characters.

If the user voice is a command to change a channel, the control unit140may display a guide message to guide change of a channel on the first area, and may display a voice item corresponding to an example of an utterable command to change a channel and a voice item corresponding to cancelation of change of a channel on the second area.

If the user voice is a command to turn off power, the control unit140may display a guide message to confirm turn-off of power on the first area, and may display a voice item corresponding to a command regarding whether to turn off power on the second area.

Hereinafter, displaying of voice assistance information will be explained with reference toFIGS. 112 to 114.

If a voice start command is input through the voice input unit110, the control unit140changes a mode of the electronic apparatus100to a voice task mode in which the electronic apparatus100is controlled in accordance with a user voice input through the voice input unit110. The control unit140displays voice assistance information as shown inFIG. 112.

The voice assistance information may display an icon820indicating that the current mode of the electronic apparatus100is the voice task mode. The voice assistance information may display a power off voice item811, a channel voice item812, a mute voice item813, and an external input voice item814on a left area of the icon820, and may display a smart hub voice item815, an apps voice item816, a search voice item817, and all voice item818on a right area of the icon820.

If the voice assistance information is displayed and a command, “channel”, corresponding to the channel voice item812is input through the voice input unit110, the control unit140changes the voice assistance information as shown inFIG. 113. The control unit140displays a guide message having first chroma on the left area of the icon820in the voice assistance information to perform a voice task. For example, as shown inFIG. 113, “Please say a channel name or a channel number810may be displayed on the left area.

The control unit140displays a voice item having second chroma on the right area of the icon820in the voice assistance information. The voice item may be a voice item corresponding to an example of a utterable command to change a channel and a voice item corresponding to cancelation of change of a channel (for example, a previous voice item). For example, as shown inFIG. 113, “(example: 11, MBC, previous channel, and etc.) Previous”11320may be displayed on the right area of the icon820.

The control unit140may control such that the chroma of the right area of the icon820is thicker than the chroma of the left area of the icon820.

If the voice assistance information is displayed as shown inFIG. 112and a command, “power off”, corresponding to the power off voice item811is input through the voice input unit110, the control unit140changes the voice assistance information as shown inFIG. 114. The control unit140displays a guide message having first chroma on the left area of the icon820in the voice assistance information to perform a voice task. For example, as shown inFIG. 114, “Do you want to turn off power?11410may be displayed on the left area of the icon820.

The control unit140displays a voice item having second chroma on the right area of the icon820in the voice assistance information. The voice item may be a voice item corresponding to a command regarding whether to turn off power. For example, as shown inFIG. 114, “Yes or No”11420and11430may be displayed on the right area of the icon820.

The control unit140may control such that the chroma of the right area of the icon820is thicker than the chroma of the left area of the icon820.

FIG. 115is a flowchart to explain a controlling method of the electronic apparatus100, which displays voice assistance information according to an exemplary embodiment.

The electronic apparatus100displays voice assistance information (S11510). The voice assistance information may include an icon indicating that a current mode of the electronic apparatus100is a voice task mode, and a plurality of voice items guiding the voice task mode.

If a user voice corresponding to one of the plurality of voice items is input through the voice input unit110, the electronic apparatus100displays a guide message having first chroma on a first area, and displays a voice item having second chroma on a second area (S11520). The first area may be a right area of the icon in the voice assistance information and the second area may be a left area of the icon in the voice assistance information. The second chroma may be thicker than the first chroma.

As described above, the utterable voice item is displayed with chroma different from that of the guide message so that the user can know which command the user should utter more clearly.

The control unit140displays voice assistance information including a plurality of voice items guiding a voice task. If a user voice input through the voice input unit110includes a pre-set word that does not belong to a command corresponding to the plurality of voice items, the control unit140may perform a voice task corresponding to the pre-set word.

The pre-set word may be a word that corresponds to an executable key included in a remote controller which is interlocked with (i.e. communicates with) the electronic apparatus100. For example, the pre-set word may include at least one of a command to generate a channel list, a command to generate a menu, a command to execute a social network, a command to guide a program schedule, a command to change to a 3D image, and a command to guide broadcast.

The pre-set word may be a word that corresponds to a command to provide a task related to a function performed by the electronic apparatus100. For example, if the electronic apparatus100currently performs a function of reproducing a moving image, the pre-set word may include at least one of a command to reproduce the moving image, a command to pause the moving image, a command to stop the moving image, a command to reproduce a previous file, a command to reproduce a next file, a command to skip forward, and a command to skip backward.

That is, a command corresponding to an essential function of the electronic apparatus100is pre-stored in the voice database130m, so that the user can use the essential function of the electronic apparatus100through voice recognition even if the function is not displayed in the voice assistance information.

Hereinafter, a case in which a command that does not belong to a voice item displayed on voice assistance information is uttered will be explained with reference toFIGS. 116 and 117.

If a voice start command (for example, “Ginny”) is input through the voice input unit110, the control unit140changes a mode of the electronic apparatus100to a voice task mode, in which the electronic apparatus100is controlled in accordance with a user voice input through the voice input unit110. If the mode is changed to the voice task mode, the control unit140displays voice assistance information on the lower portion of the display screen as shown inFIG. 116.

At this time, an icon820indicating that the current mode of the electronic apparatus100is the voice task mode is displayed on the voice assistance information. The voice assistance information displays a power off voice item811, a channel voice item812, a mute voice item813, and an external input voice item814on a left area of the icon820, and displays a smart hub voice item815, an apps voice item816, a search voice item817, and an all voice item818on a right area of the icon820.

If the voice assistance information is displayed and a command, “channel list”, which does not belong to the voice assistance information, is input through the voice input unit110, the control unit140may displays a channel list11700on one side portion of the display screen as shown inFIG. 117.

The channel list11700includes a broadcast channel that falls within a pre-set number range with reference to a currently tuned broadcast channel. For example, if the currently tuned broadcast channel is “9-1 KBS2”, the control unit140displays “6-1 SBS”, 7-1 KBS 1”, “9-1 KBS 2”, “11-1 MBC”, and “13-1 EBS” in the channel list1170as shown inFIG. 117.

The user may change the channel by selecting one of the channels in the channel list11700. Accordingly, even if the voice assistance information does not display a voice item corresponding to the channel list, the user can perform a task of displaying the channel list through voice recognition.

FIG. 118is a flowchart to explain a controlling method of the electronic apparatus100if a command that does not belong to a voice item displayed on voice assistance information is uttered according to an exemplary embodiment.

The electronic apparatus100displays voice assistance information (S11810). The voice assistance information may include an icon indicating that a current mode of the electronic apparatus100is a voice task mode and a plurality of voice items guiding the voice task mode.

The electronic apparatus100receives input of a command other than commands corresponding to the voice items (S11820). If the command other than the commands corresponding to the voice items may be a word that corresponds to an executable key included in a remote controller which communicates with the electronic apparatus100. For example, the word may include one of a command to generate a channel list, a command to generate a menu, a command to execute a social network, a command to guide a program schedule, a command to change to a 3D image, and a command to guide broadcast.

The command other than the commands corresponding to the voice items may be a word that corresponds to a command to provide a task related to a function currently performed by the electronic apparatus100. For example, if the electronic apparatus100currently performs a function of reproducing a moving image, the word may include at least one of a command to reproduce the moving image, a command to pause the moving image, a command to stop the moving image, a command to reproduce a previous file, a command to reproduce a next file, a command to skip forward, and a command to skip backward.

The electronic apparatus100performs a voice task in accordance with the input command (S11830). For example, if a command to generate a channel list is input, the electronic apparatus100generates and displays a channel list.

As described above, the user can perform a task corresponding to a command that is not displayed in the voice assistance information.

The control unit140may perform not only a motion task mode using one hand but also a motion task mode using both hands.

Specifically, if a motion start command using both hands is input through the motion input unit120, the control unit140may change a mode of the electronic apparatus100to a motion task mode using both hands to perform a motion task using both hands.

In a motion task mode using one hand, if a motion start command using the other hand is input, the control unit140may recognize the motion start command using both hands. Specifically, if a motion start command (a motion of shaking one hand 3˜4 times) is input through the motion input unit120as shown inFIG. 119, the control unit140changes a mode of the electronic apparatus100to a motion task mode, in which the electronic apparatus100is controlled in accordance with a user motion input through the motion input unit120. If a motion start command using the other hand is input through the motion input unit120in the motion task mode, the control unit140may change the mode of the electronic apparatus100to a motion task mode using both hands to perform a motion task using both hands.

In another exemplary embodiment, the motion start command using both hands may be recognized if a shake motion of shaking both hands simultaneously multiple times (for example, 3˜4 times) is input. Specifically, if the shake motion of shaking both hands simultaneously multiple times is input through the motion input unit120as shown inFIG. 120, the control unit140may change a mode of the electronic apparatus100to a motion task mode using both hands to perform a motion task using both hands.

The motion task using both hands may be a task of enlarging or reducing a display screen.

In particular, if an application where it is impossible to perform the motion task using both hands is executed, the control unit140may output a message that it is impossible to perform the motion task using both hands. For example, if the application where it is impossible to perform the motion task using both hands is executed, the control unit140may display an icon indicating that it is impossible to perform the motion task using both hands.

FIG. 121is a flowchart to explain a motion task mode using both hands according to an exemplary embodiment.

The electronic apparatus100receives input of a motion start command using both hands (S12110). For example, in a motion task mode using one hand, if a motion start command using the other hand is input, the motion start command using both hands is recognized as being input.

In another exemplary embodiment, the motion start command using both hands may be recognized if a shake motion of shaking both hands simultaneously multiple times (for example, 3˜4 times) is input.

If the motion start command using both hands is input, the electronic apparatus100changes a mode of the electronic apparatus100to a motion task mode using both hands to perform a task of the electronic apparatus using both hands. (S12120). The motion task mode using both hands may be task of enlarging or reducing a display screen.

As described above, the user can perform a motion task using not only one hand but also both hands.

If a motion start command is input through the motion input unit120, the control unit140changes a mode of the electronic apparatus100to a motion task mode, in which a motion task is performed in accordance with a motion of a user who inputs the motion start command. In the motion task mode, the motion task is performed only in accordance with the motion of the user who inputs the motion start command until the user who inputs the motion start command releases the motion task mode. The motion task mode is maintained even if a motion start command is input from other users than the user who inputs the motion start command.

Specifically, if a motion start command is input through the motion input unit120, the control unit140traces a hand of a user who inputs the motion start command using the motion recognition module130l. The control unit140may trace the user hand using at least one of shape, color, and motion of the user hand.

Even if a motion start command of a hand of another user is input through the motion input unit120, the control unit140does not perform a motion task by the hand of another user, and traces the hand of the user who initially inputs the motion start command and performs a motion task.

Even if a motion start command is input by another user, the control unit140may perform the motion task in accordance with the motion of the user who initially inputs the motion start command until a command to release the motion task mode is input from the user who inputs the motion start command.

Even if the hand of the user who inputs the motion start command is overlapped with hands of other users in the motion task mode, the motion task may be performed in accordance with the motion of the user who inputs the motion start command.

Alternatively, if a motion start command using one hand is input and another motion start command using one hand of a user other than the user who inputs the motion start command is input, the control unit140may change the mode of the electronic apparatus100to a motion task mode using both hands to perform a motion task using both hands. The motion task mode using both hands may be performed by one hand of the user who initially inputs the motion start command and one hand of another user.

If a plurality of motion start commands are input from a plurality of users through the motion input unit120, the control unit140determines a motion start command that is initially input from among the plurality of motion start commands. If the initially input motion start command is determined, the control unit140changes a mode of the electronic apparatus100to a motion task mode in which a motion task is performed in accordance with a motion of the user who initially inputs the motion start command.

The motion task may be performed only in accordance with the motion of the user who initially inputs the motion start command until the user who initially inputs the motion start command releases the motion task mode. The motion task mode may be maintained even if a motion start command is input from other users than the user who initially inputs the motion start command.

FIG. 122is a flowchart to explain a controlling method of the electronic apparatus100if a plurality of motion start commands are input from a plurality of users according to an exemplary embodiment.

The electronic apparatus100receives input of a plurality of motion start commands from a plurality of users through the motion input unit120(S12210). The motion start command may be a shake motion of shaking a user's hand multiple times (for example, 3˜4 times).

The electronic apparatus100determines a motion start command that is initially input from among the plurality of motion start commands (S12220). Specifically, the electronic apparatus100may determine the initially input motion start command using a shape, color, and a motion of the user hand which is used for inputting the motion start command.

The electronic apparatus100performs a motion task using the motion of the user who initially inputs the motion start command (S12230). Specifically, if the electronic apparatus100determines the initially input motion start command, the electronic apparatus100changes a mode of the electronic apparatus100to a motion task mode in which a motion task is performed in accordance with a motion of the user who initially inputs the motion start command. The electronic apparatus100performs a motion task using a motion of the user who initially inputs the motion start command in the motion task mode.

The motion task may be performed only in accordance with the motion of the user who initially inputs the motion start command until the user who initially inputs the motion start command releases the motion task mode. The motion task mode may be maintained even if a motion start command is input from other users than the user who initially inputs the motion start command.

As described above, the motion task is performed in accordance with the initially input motion start command so that a malfunction by motions of other users can be prevented.

The control unit140may perform a voice task in phases. Specifically, if a first voice of a user is input through the voice input unit110, the control unit140may display a first menu guiding at least one voice task on one area of an image in response to the first voice. If a second voice of the user is input through the voice input unit110, the control unit140may perform a voice task corresponding to the second voice of the user from among at least one voice task.

For example, if a command to change a channel is input through the voice input unit110, the control unit140may display a first menu including information for guiding change of a channel. If a user voice corresponding to a channel identifier (for example, one of a channel number, a channel name, and a program name) is input through the voice input unit110, the control unit140may change a current channel to a channel corresponding to the user voice.

If a user voice corresponding to a program name is input through the voice input unit110, the control unit140searches for the program name input through the voice input unit110from a pre-stored program guide (EPG), and changes a current channel to a channel to broadcast the input program name or schedules a watching time.

Hereinafter, a case in which voice recognition is performed in phases will be explained with reference toFIGS. 123 to 125.

If a voice start command is input through the voice input unit110, the control unit140changes a mode of the electronic apparatus100to a voice task mode in which the electronic apparatus100is controlled in accordance with a user voice input through the voice input unit110. The control unit140displays voice assistance information including a plurality of voice items as shown inFIG. 123.

If the voice assistance information is displayed and a user voice (for example, “channel”) corresponding to a channel voice item812is input through the voice input unit110, the control unit140changes the voice assistance information and displays a first menu guiding performance of a voice task. For example, the control unit140may display “Please say a channel name or a channel number”12410to guide change of a channel as shown inFIG. 124.

If a user voice corresponding to one of a channel number, a channel name, and a broadcast program name is input through the voice input unit110, the control unit140changes a current channel to a channel corresponding to the user voice. For example, if “7” is input through the voice input unit110, the control unit140displays channel 7 by tuning to channel 7 as shown inFIG. 125.

As described above, the voice task is performed in phases so that a malfunction can be prevented. Specifically, if the user wishes to change a channel, the user changes the channel after selecting the channel voice item once and thus can avoid changing to an undesirable channel.

FIG. 126is a flowchart to explain a controlling method of the electronic apparatus100which performs a voice task in phases according to an exemplary embodiment.

The electronic apparatus100displays an image (S12610). The image may include voice assistance information.

The electronic apparatus100receives input of a first voice through the voice input unit110(S12620). The first voice may be a user voice that corresponds to one of a plurality of voice items included in the displayed voice assistance information.

The electronic apparatus100displays a first menu guiding performance of a voice task in response to the input first voice (S12630).

The electronic apparatus100receives input of a second voice through the voice input unit110(S12640). The second voice is a command to perform a specific voice task.

The electronic apparatus100performs a voice task corresponding to the second voice in response to the input second voice (S12650). For example, if the second voice is a channel name, the electronic apparatus100changes a broadcast channel to a channel corresponding to the second voice.

As described above, the voice task is performed in phases so that a malfunction can be prevented.

In a voice task mode in which a voice task is performed in accordance with a user voice input through the voice input unit110, the control unit140displays at least one executable icon and a name of the executable icon.

The voice input unit110receives input of a user voice. If a first executable icon displaying only a part of a name of the executable icon exists among the at least one executable icon, and the input user voice is consistent with the displayed part of the name of the first executable icon, the control unit140executes the first executable icon.

If the input user voice is consistent with a plurality of spellings constituting the displayed part of the name of the first executable icon, the control unit140executes the first executable icon.

If a second executable icon whose name includes a special character exists among the executable icons and the input user voice is consistent with an utterable name excluding the special character included in the name of the second executable icon, the control unit140executes the second executable icon.

The special character may be a symbol that is not utterable by the user. For example, the special character may be, but not limited to, a question mark (?), a comma (,), and a period (.).

For example, if an application having a name of an executable icon, “face recognition, voice recognition”, exists, the control unit140executes the application when a user voice, “face recognition, voice recognition”, is input through the voice input unit110.

In the above example, the control unit140performs the executable icon. However, this is merely an example and the technical idea of the present disclosure may be applied if the control unit140performs a hyperlink.

Hereinafter, a method for executing an executable icon displaying a part of a name of the executable icon according to an exemplary embodiment will be explained with reference toFIGS. 127 and 128.

The control unit140displays a content list (for example, a smart hub) including a plurality of executable icons for executing an application according to a specific command of a user. If an executable icon whose name has a number of characters exceeding a predetermined number is included among the plurality of executable icons included in the content list, the control unit140may display only a part of the entire name of the executable icon. For example, if an executable icon whose name has more than 10 characters is included among the plurality of executable icons included in the content list, the control unit140does not display the entire name of the executable icon, “Exciting Drum”, and displays only “Exciting” as shown inFIG. 127.

If the content list is displayed and a voice start command is input through the voice input unit110, the electronic apparatus100changes a mode of the electronic apparatus100to a voice task mode in which the electronic apparatus is controlled in accordance with a user voice input through the voice input unit110. If the mode is changed to the voice task mode, the electronic apparatus100displays voice assistance information as shown inFIG. 127.

If the voice assistance information is displayed and “Exciting”, which is consistent with the displayed part of the name, is uttered through the voice input unit110, the control unit140executes “Exciting Drum” as shown inFIG. 128.

Also, if the voice assistance information is displayed and a plurality of spellings, “E”, “X”, “C”, “I”, “T”, “I”, “N”, and “G”, which constitute the displayed part of the name, are input through the voice input unit110, the control unit140executes “Exciting Drum” as shown inFIG. 128.

FIG. 129is a flowchart to explain a method for executing an executable icon displaying only a part of a name of the executable icon according to an exemplary embodiment.

The electronic apparatus100changes a mode of the electronic apparatus100to a voice task mode in response to a voice start command input through the voice input unit110(S12910). The electronic apparatus100displays a content list including a plurality of executable icons for executing an application.

In particular, the electronic apparatus100displays an executable icon displaying a part of a name of the executable icon on the content list (S12920). This is because the name of the executable icon has a number of characters exceeding a predetermined number and thus the entire name of the executable icon cannot be displayed.

The electronic apparatus100receives input of a user voice through the voice input unit110(S12930).

The electronic apparatus100determines whether the user voice input through the voice input unit110is consistent with the displayed part of the name (S12940).

Also, referring toFIG. 3, various software modules are stored in the storage unit130. However, the software modules are not necessarily stored in one storage unit130.

That is, the voice recognition module and the motion recognition module may be stored in separate storage units, respectively. Accordingly, the voice recognition module may recognize a user voice from a voice signal input from a microphone and may provide a result of the recognition to the control unit140. Also, the motion recognition module may recognize a user motion using an image signal photographed by a camera and may provide a result of the recognition to the control unit140.

Also, the voice recognition module and the motion recognition module may be stored in separate external apparatuses, respectively. For example, a voice recognition apparatus including a microphone may recognize a user voice using a voice recognition module and then may provide a result of the recognition to the electronic apparatus100. Likewise, a motion recognition apparatus including a camera may recognize a user motion using a motion recognition module and then may provide a result of the recognition to the electronic apparatus100.

A program code to perform the above-described controlling methods may be stored in various types of recording media. Specifically, the program code may be stored in various types of recording media readable by a terminal apparatus, such as a random access memory (RAM), a flash memory, a read only memory (ROM), an erasable programmable ROM (EPROM), an electronically erasable and programmable ROM (EEPROM), a register, a hard disk, a removable disk, a memory card, a USB memory, a CD-ROM, etc.
