According to an exemplary embodiment, an augmented remote controller may identify an object around a user and provide information related to the identified object to the user, thereby offering an augmented reality environment to the user. The object around the user may be an image display apparatus that is controllable using the augmented remote controller, an external device connected to the image display apparatus, contents available from the image display apparatus or the external device, or other types and/or other types of objects.
The augmented remote controller may identify an object around the user by collecting user-related information. For example, the augmented remote controller may collect information regarding location or bearing of the user using a Global Positioning System (GPS) or a compass. Further, the augmented remote controller may capture an image of a real environment of the user by a camera and thus identify an object around the user.
The augmented remote controller may also identify an object around the user using a Radio Frequency Identification (RFID) reader.
The augmented remote controller may identify an object around the user, search for information related to the identified object, and display the detected (or determined) information. The type of the detected (or determined) information may correspond to the type of the identified object.
For example, when the augmented remote controller identifies an image display apparatus or an external device around the user, the augmented remote controller may search for information about a content list available from the image display apparatus or the external device. Additionally, the augmented remote controller may search for information about a user interface through which the image display apparatus or the external device can be controlled. The augmented remote controller may display the detected information about the image display apparatus or the external device to the user.
The augmented remote controller may identify contents provided by an image display apparatus or an external device around the user. The augmented remote controller may search for information about content and display detected information to the user. The augmented remote controller may display a user interface through which the user can edit, play back, and/or transmit contents provided by the image display apparatus or the external device.
The augmented remote controller may identify any other type of object around the user. For example, the user may capture an image of a piece of furniture around the user using a camera provided in the augmented remote controller. The augmented remote controller may identify that the object captured by the camera is a piece of furniture, by referring to a database that stores information about images of a number of objects. The augmented remote controller may search for information regarding the furniture, such as name or manufacturer of the furniture, and display the detected (or determined) information to the user.
The augmented remote controller may augment a real image captured by the camera with detected information about an object captured by the camera. For example, the augmented remote controller may display a real image captured by the camera on a display, search for information about an object included in the displayed real image, and display the detected information about the object on the display using a pop-up window or an icon. Additionally, the augmented remote controller may display the detected information about the object as an image or as text on the display.
The user may view, through the augmented remote controller, the real image augmented with the information detected by the augmented remote controller. The user may identify information about the real image or an object included in the real image by the augmented information overlaid on the real image captured by the camera.
If the display that displays the augmented real image is a touch screen, the user may interact with the augmented remote controller by selecting a pop-up window, an icon, an image, and/or text representing the augmented information. For example, when the user selects a pop-up window representing first augmented information, the augmented remote controller may execute an application related to the first augmented information. The application may be an application that controls an object such as an image display apparatus or an external device included in the augmented real image.
If the augmented remote controller uses a transparent display, the augmented remote controller may display augmented information overlaid on a real image projected onto the transparent display. The augmented remote controller may search for information regarding an object included in the displayed real image and display the detected information as augmented information on the transparent display.
The augmented remote controller may wirelessly transmit signals to and receive signals from an image display apparatus or an external device connectable to the image display apparatus. The user may control the image display apparatus or the external device using the augmented remote controller. The augmented remote controller may receive information about operation status of the image display apparatus or the external device and display the received information on the display.
The augmented remote controller may be connected to a network including the Internet. The augmented remote controller may search for information regarding an identified object through the network and display the detected information on the display.

The coordinate calculator of the augmented remote controller interface 140 may correct handshakes or errors in the signal corresponding to movement of the augmented remote controller 200 received through the wireless communication module of the augmented remote controller interface 140. After correcting handshakes or errors, the coordinate calculator may calculate x and y coordinates of the target position at which the pointer should be displayed on the display 180.
The controller 150 may identify a movement or key manipulation of the augmented remote controller 200 from a signal received from the augmented remote controller 200 through the augmented remote controller interface 140 and may thus control an operation of the image display apparatus 100 based on the identified movement or key manipulation.
In another example, the augmented remote controller 200 may calculate coordinates of a target position to which the pointer should be moved in correspondence with movement of the augmented remote controller 200 and may output the calculated coordinates to the augmented remote controller interface 140. The augmented remote controller interface 140 may transmit information regarding the received pointer coordinates to the controller 150 without correcting handshakes or errors.
The controller 150 may provide overall control to the image display apparatus 100. The controller 150 may receive a signal from the augmented remote controller 200 through the augmented remote controller interface 140. The controller 150 may also receive a command through a local key of the image display apparatus 100.

The A/V processor 170 may select an audio signal and/or a video signal to be processed according to a user command received through the controller 150. The audio signal and/or the video signal processed by the A/V processor 170 are output through the audio output unit 185 and/or the display 180. The user command may be a broadcast channel selection command, a command to select a content to be played from among content input to the image display apparatus 100, and/or the like.
In accordance with an exemplary embodiment, the A/V processor 170 may process a video signal so that an external input two-dimensional (2D) or three-dimensional (3D) video signal is displayed on the display 180. The A/V processor 170 may process a video signal such that a user interface created by the user interface controller is displayed in 3D on the display 180. The A/V processor 170 may be described below in great detail with reference to
The display 180 may generate a driving signal by converting a video signal, a data signal, and/or an OSD signal processed by the A/V processor 170, or a video signal and/or a data signal received through the external device I/O unit to an RGB signal. The display 180 may be any one of various types of displays such as a Plasma Display Panel (PDP), a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED), and/or a flexible display. According to an exemplary embodiment, the display 180 may be capable of displaying 3D images.
For 3D visualization, the display 180 may be configured into an auto-stereoscopic 3D display (glasses-free) and/or a traditional stereoscopic 3D display (with glasses).
Auto-stereoscopy is a method of displaying 3D images without any auxiliary device, for example, special polarization glasses on the part of a user. Thus, the display 180 may display 3D images on its own. Renticular and parallax barrier are examples of auto-stereoscopic 3D imaging.
The traditional stereoscopy may require an auxiliary device besides the display 180 in order to display 3D images. The auxiliary device may be a Head Mount Display (HMD) type, a glasses type, etc. As special 3D glasses, there are polarization glasses, shutter glasses, and a spectrum filter.
The display 180 may also be implemented as a touch screen so that it is used not only as an output device, but also as an input device.
The audio output unit 185 may receive a processed audio signal (e.g. a stereo signal, a 3.1-channel signal or a 5.1-channel signal) from the A/V processor 170 and output the received audio signal as voice. The audio output unit 185 may be implemented as any of various types of speakers.

The demodulator 171 may demodulate a broadcast signal received from the broadcast signal receiver 110. For example, the demodulator 171 may receive a digital IF signal DIF from the broadcast signal receiver 110 and demodulate the digital IF signal DIF. The demodulator 171 may also perform channel decoding. For channel decoding, the demodulator 171 may include a convolutional decoder (not shown), a deinterleaver (not shown) and a Reed-Solomon decoder (not shown), and perform convolutional decoding, de-interleaving and Reed-Solomon decoding.
The demodulator 171 may perform demodulation and channel decoding on the digital IF signal received from the broadcast signal receiver 110, thereby obtaining a stream signal TS. The stream signal TS may be a signal in which a video signal, an audio signal and/or a data signal are multiplexed. For example, the stream signal TS may be an Moving Picture Experts Group-2 (MPEG-2) Transport Stream (TS) signal obtained by multiplexing an MPEG-2 video signal and a Dolby AC-3 audio signal. The MPEG-2 TS signal may include a 4-byte header and a 184-byte payload.
In order to properly handle not only ATSC signals but also DVB signals, the demodulator 171 may include an ATSC demodulator and a DVB demodulator. The demodulator 171 may output the stream signal TS to the DEMUX 172.
The DEMUX 172 may demultiplex the stream signal TS, for example, an MPEG-2 TS into an audio signal, a video signal, and a data signal. The DEMUX 172 may receive the stream signal from the demodulator 171, the network interface 120, and/or the external device I/O unit 130.
The data signal obtained by demultiplexing the input stream signal may be a coded data signal. The coded data signal may include Electronic Program Guide (EPG) information that provides broadcasting information such as titles and start and end times of broadcast programs played on each broadcast channel. For example, the EPG information may be ATSC-Program and System Information Protocol (TSC-PSIP) information in case of ATSC, whereas it may be DVB-Service Information (DVB-SI) in case of DVB.
The decoder 173 may decode the demultiplexed signals. In this exemplary embodiment, the decoder 173 may include a video decoder for decoding the demultiplexed video signal, and a scaler for controlling resolution of the decoded video signal to a resolution level at which the decoded video signal can be output in the image display apparatus 100.
In accordance with an exemplary embodiment, the A/V processor 170 may further include a mixer for mixing an external video signal input to the image display apparatus 100 with a video signal generated from the user interface controller. While the mixer may be incorporated into the formatter 175 in function, the mixer may be described herein as separate from the formatter 175, for ease of convenience. The display 180 may display an image based on a mixed video signal. The mixer may output the mixed video signal to the formatter 175.
The formatter 175 may identify a format of the mixed video signal referring to a data signal related to the video signal. The formatter 175 may convert the video signal to a format suitable for the display 180 and output the converted video signal to the display 180.
In this exemplary embodiment, the image display apparatus 100 may display a 3D image on the display 180. The formatter 175 may create a 3D video signal in a predetermined format by separating the mixed video signal into multi-view point image signals and may output the 3D video signal to the display 180. The display 180 may display a 3D image based on the 3D video signal.
A 3D image may be formed with multi-viewpoint images. The user may view the multi-viewpoint images with his or her left and right eyes. Disparity between the multi-viewpoint images viewed by the left and right eyes may provide the illusion of 3D to the user. The multi-viewpoint images that form the 3D image may be a left-eye image perceivable to the left eye and a right-eye image perceivable to the right eye.
The format of a 3D video signal may be determined according to the laybut of the left-eye and right-eye images of the 3D video signal. The left-eye and right-eye images may be provided on the left and right sides, respectively. This may be called a side by side format. The left-eye and right-eye images may be arranged vertically in a top-down format. A time-division layout of the left-eye and right-eye images may be called a frame sequential format. The left-eye and right-eye images may alternate with each other line by line. This may be called an interlaced format. The left-eye and right-eye images may be mixed in the form of boxes in a checker box format.
A video signal included in an external signal input to the image display apparatus 100 and a GUI video signal created from the user interface controller may be 3D video signals with which 3D images are realized. The mixer may mix these 3D video signals and output the mixed 3D video signal to the formatter 175.
The formatter 175 may identify the format of the mixed 3D video signal referring to a related data signal. The formatter 175 may process the 3D video signal according to the identified format and output the processed 3D video signal to the display 180. If limited 3D image formats are available to the display 180, the formatter 175 may convert the received 3D video signal to a 3D image format in which the display 180 can display a 3D image and output the converted 3D video signal to the display 180.
If the formatter 175 fails to identify the format of the mixed video signal referring to the related data signal, it may use a predetermined algorithm to thereby identify the format. For example, the formatter 175 may identify the format of an input 3D video signal by analyzing edges of an image created based on the input 3D video signal.
If the input mixed video signal is a 2D video signal that allows 2D visualization, the formatter 175 may generate a 3D video signal using a 2D-3D conversion algorithm.

The augmented remote controller 200 may identify an object around (or about) the user, referring to the user-related information collected by the sensor unit 240. The augmented remote controller 200 may also identify a user's gesture, referring to the collected user-related information. The augmented remote controller 200 may be controlled based on a command corresponding to the user's gesture. If the command corresponding to the user's gesture is a command to control an electronic device, the augmented remote controller 200 may transmit a signal carrying the control command to the electronic device.
The identification unit 250 may identify (or determine) an object around (or about) the user, such as an electronic device. The identification unit 250 may include a camera, an RFID reader, an IR sensor, etc. The identification unit 250 may capture an image of the object using the camera. The captured image of the object may be compared with images of various objects stored in the storage 220, the home server 50, and/or the network server 300. The identification unit 250 may analyze a pattern of the image and extract information about an object corresponding to an image with a pattern matching with the pattern of the captured image, thereby identifying (or determining) the object.
The identification unit 250 may also identify an object by reading an RFID tag attached to the object using the RFID reader. Alternatively or additionally, the identification unit 250 may determine presence or absence of any object around the user using the IR sensor. The augmented remote controller 200 may refer to information regarding objects matching user positions or bearings. The information regarding the objects matching the user positions or bearings may be stored in the storage 220, the home server 50, and/or the network server 300.
The identification unit 250 may identify a current location and bearing of user based on the user-related information collected by the sensor unit 240 and may extract information about an object whose presence was sensed by the IR sensor, corresponding to the user location and bearing, from the stored information regarding objects, thus identifying the object around the user (or about the user). For example, the augmented remote controller 200 may refer to map information including information regarding buildings corresponding to user locations and bearings. In this example, the augmented remote controller 200 may identify a building around the user, referring to information regarding objects corresponding to the location and bearing of the user that is carrying the augmented remote controller 200 in the map information.
The identification unit 250 may also identify a face, finger print, and/or iris of a person captured by the camera. The identification unit 250 may identify the person by comparing a pattern of the identified face, finger print, and/or iris with stored patterns of faces, finger prints, and/or irises. The controller 280 may search for information regarding an object identified by the identification unit 250. For example, if the identification unit 250 identifies a person, the controller 280 may search for information regarding the person such as name, age, and preferred contents of the person and output the detected information.
The audio I/O unit 270 may recognize the user by receiving a voice signal from the user.
The display 260 and the audio I/O unit 270 may output an image and a sound corresponding to a manipulation of the user interface 230 or a signal received from an electronic device such as the image display apparatus 100, the external device 30, the home server 50, and/or the network server 300. Thus, the user may determine from the display 260 and the audio I/O unit 270 whether the user interface 230 has been manipulated or the electronic device has been controlled.
The audio I/O unit 270 may be configured separately as an audio input unit and an audio output unit.
The display 260 may display information regarding an object included in an image captured by the camera. The display 260 may display an augmented real image obtained by superimposing detected augmented information on the captured image. In another example, if the display 260 is implemented as a transparent display with a transparent panel, the user may view a real image of his or her environment on the transparent display 260. The augmented remote controller 200 may search for information regarding an object included in the real image displayed on the transparent display 260 and thus may display the determined object-related information on the transparent display 260.
The controller 280 may superimpose the augmented information on the captured image and may thus output the augmented real image to the display 260. The controller 280 may output an augmented information-related video signal to the display 260 so that the augmented information about the object included in the real image projected onto the transparent display 260 may be superimposed on the real image. The controller 280 may provide overall control to the augmented remote controller 200.
The controller 280 may transmit a signal corresponding to a manipulation of a particular key of the user interface 230 or a signal corresponding to an operation of the augmented remote controller 200 sensed by the sensor unit 240 to an electronic device through the wireless communication module 210.
The block diagrams of the image display apparatus 100 and the augmented remote controller 200 shown in
As shown in
The augmented remote controller 200 may identify various types of objects around the user. The user may select an intended type of object through the augmented remote controller 200. For example, the user may select an electronic device so that the augmented remote controller 200 may identify or determine the electronic device. The augmented remote controller 200 may identify the electronic device around the user by using an RFID tag attached to the electronic device.
The user may select contents available from the image display apparatus 100 or the external device 200 as objects to be identified (or determined). The augmented remote controller 200 may identify or determine a content provided by the image display apparatus 100 or the external device 200 using metadata received from the image display apparatus 100, the external device 30, and/or the home server 50. That is, if an identification device such as the camera or RFID reader provided in the augmented remote controller 200 points to the image display apparatus 100, the augmented remote controller 200 may identify the image display apparatus 100 playing a content (i.e., playable content) that the user wants to be identified, and the augmented remote controller 200 may then identify the content being played in the image display apparatus 100 based on metadata related to the image display apparatus 100.
Additionally, the user may select a person for identification. In this example, the augmented remote controller 200 may read a face, finger print, and/or iris of the person by use of the camera, a finger print identifier, and/or an iris identifier in the identification unit 250. The augmented remote controller 200 may identify the person by comparing the read information with information about the faces, finger prints, and/or irises of persons stored in a database.
The augmented remote controller 200 may also recognize a person from a voice input of the person.
The user may also select an object around (or about) him or her (e.g. a building, furniture, etc.). In this example, the augmented remote controller 200 may collect information about location or bearing of the user by GPS or compass. The augmented remote controller 200 may also capture an image of the object using the camera and identify the captured object, by referring to image information about objects corresponding to the current user location or bearing in the database that stores information about objects by user location and bearing.
Information that the augmented remote controller 200 refers to for identifying an object may be stored in the image display apparatus 100, the external device 30, the storage 220 (of the augmented remote controller 200), the home server 50, and/or the network server 300. Thus, the augmented remote controller 200 may search for information regarding an identified object in the image display apparatus 100, the external device 30, the storage 220 (of the augmented remote controller 200), the home server 50, and/or the network server 300.
For example, when the augmented remote controller 200 identifies or determines the image display apparatus 100 or the external device 30, the augmented remote controller 200 may search for a list of contents being played in the image display apparatus 100 or the external device 30. The augmented remote controller 200 may also search for a list of contents stored in the image display apparatus 100 or the external device 30. Additionally, the augmented remote controller 200 may search for information regarding a broadcast signal received at the image display apparatus 100. The augmented remote controller 200 may also search for information including menus with which to control the image display apparatus 100 or the external device 30.
When the augmented remote controller 200 identifies or determines a content being played or stored in the image display apparatus 100 or the external device 30, the augmented remote controller 200 may search for information related to the content. The content-related information may be a title of the content, shopping information for the content, etc.
If the augmented remote controller 200 identifies or determines a person, the augmented remote controller may search for information regarding the person. The person-related information may specify a name, an age, a job and/or a phone number of the person, contents that the person prefers, and/or a history of contents that the person has viewed.
If the augmented remote controller 200 identifies or determines a real object around the user (e.g. a building, furniture, etc.), the augmented remote controller 200 may search for information related to the object. The object-related information may specify name, manufacturer, price, store, and/or use guide of the object.
The augmented remote controller 200 may display the determined (or detected) information on the display 260. The determined information may be displayed in a pop-up window or as an icon. The determined information may be displayed as an image or as text. The augmented remote controller 200 may display the determined augmented information superimposed on an image captured by the camera.
The controller 280 may configure a screen of the display 260 that determined information does not overlap with an object corresponding to the determined information from among the objects included in the real environment of the user. When displaying augmented information on the transparent display, the controller 280 may also configure a screen of the display 260 such that the augmented information is displayed without being overlapped with an object corresponding to the augmented information.
As shown in
In this exemplary embodiment, the object 1001 identified by the augmented remote controller 200 may be a real image of an object captured by the camera of the augmented remote controller 200. The object-related information 1002 and 1003 may be augmented information including information determined (or detected) by the augmented remote controller 200. As shown in
The object-related information may include a menu for controlling the object. In the exemplary embodiment, the second object-related information 1003 (related information 2) may be a menu by which a command may be input to the image display apparatus 100 or the external device 30. The related information 2 may also be a menu by which the current playback of a content may be discontinued or the content may be transmitted to another electronic device.
When the screen 261 is displayed on a touch screen, the user may select the object-related information 1002 and 1003 on the screen 261 by touching the touch screen. Additionally, the user may enter a command (corresponding to a particular icon) to the augmented remote controller 200 by selecting the icon in the menu included in related information 2 displayed on the screen 261.
The augmented remote controller 200 may also include a keypad 231. The user may enter a particular command to the augmented remote controller 200 by manipulating a predetermined key of the keypad 231.
As shown in
The electronic device may be an image display apparatus, an external device connectable to the image display apparatus, an external device that stores contents, and/or a storage.
In an exemplary embodiment, once an electronic device is identified (or determined), contents may be automatically searched for in the electronic device and the content may be displayed. Alternatively, upon receipt of a search command, the augmented remote controller 200 may search for content in the electronic device.
Referring to
In this exemplary embodiment, the augmented remote controller 200 may display an image of a real environment captured by the camera and determined information regarding an object on the screen 261.
The camera of the augmented remote controller 200 may capture an environment opposite to the user with respect to the augmented remote controller 200.
Among objects displayed on the screen 261, a first object 1001 may represent the image display apparatus 100, which is an electronic device controllable by the augmented remote controller 200.
In an exemplary embodiment, the image display apparatus 100 may be powered-on or powered-off. The augmented remote controller 200 may determine, for example, from a marker attached to the image display apparatus 100 that a current object captured by the camera is the image display apparatus 100. In another exemplary embodiment, the augmented remote controller 200 may determine from a pattern of a captured image of the image display apparatus 100 that an object included in a current image captured by the camera is the image display apparatus 100.
In another exemplary embodiment, the augmented remote controller 200 may transmit a signal to and receive a signal from the image display apparatus 100 according to a predetermined wireless communication standard. In this example, the augmented remote controller 200 may determine from metadata included in a received signal that a target device that has transmitted the signal is the image display apparatus 100. The augmented remote controller 200 may transmit signals to and receive signals from a target device by IR or RF communication.
The augmented remote controller 200 may identify or determine a target device through the home server 50 that stores information about the target device. That is, the augmented remote controller 200 may receive information regarding a current object projected onto the transparent display or captured by the camera from the home server 50 and acquire information about the type of the target device and contents stored or played in the target device.
The user may search for content that can be played in the target device through the augmented remote controller 200. As shown in
The user may enter a keyword related to intended contents through the third object 1003. The keyword may be displayed on the fourth object 1004. The user may want to search for movie-related contents that can be displayed in the image display apparatus 100, which is a target device, and other electronic devices. Accordingly, the user may enter a keyword ‘MOVIE’ through the third object 1003 and thus the keyword ‘MOVIE’ may be displayed on the fourth object 1004.
Referring to
The playable contents may be contents stored in the electronic device and/or contents based on signals received at the electronic device.
A locked status or a non-locked status may be determined from metadata related to the contents, which is received through the electronic device. That is, lock setting information regarding the contents may be included in the metadata.
The lock setting information may be received directly from the electronic device.
If the augmented remote controller 200 search for contents or content-related information stored in an electronic device connected to a network through a network server or a home server, the augmented remote controller 200 may determine whether the contents or the content-related information has been set as locked (or is in a locked status) based on content-related metadata received from the network server or the home server.
That is, the method for operating the augmented remote controller may include accessing the network server or the home server of the home network over a wireless communication network, and receiving lock setting information from the network server or the home server.
In an exemplary embodiment, the augmented remote controller may determine contents that are set as locked (or in a locked status) during searching for contents stored in the electronic device, such as the image display apparatus or the external device.
Information required for releasing locked contents may be stored on a content basis. The information required for releasing locked content may include user authentication information such as a password, information about a user's finger print, and/or information about a user's iris, for example.
The locked contents may contents on which an age limit is enforced for viewing by rating or may be contents that the user has set as locked.
The contents set as locked (or in a locked status) may include contents having an age limit from among broadcast contents received in the image display apparatus, contents having an age limit from among contents provided by a content provider that may be included in the network server, or contents set as locked by the user from among contents stored in the image display or the external device.
In presence of content that have been set as locked (and thus require user authentication), the controller 280 may control the display to display, in operation S830, displayed object indicating that the contents are locked.
The augmented remote controller 200 may display an icon indicating a locked status, rather than displaying content-related information.
As shown in
For content set as locked (or in a locked state), objects 1006 and 1007 (including a lock icon) may be displayed on the screen 261. The objects 1006 or 1007 (or lock icon) may indicate a locked status. The object 1006 indicating that a content has been set as locked by the user may be displayed separately from the object 1007 indicating that a content has an age limit.
If an electronic device (such as an image display apparatus, an external storage, or a DVD player) is locked, the augmented remote controller 200 may display a real image of the electronic device augmented with a lock icon, not with content information. If the lock icon is touched or a predetermined input is applied, a user authentication may be performed.
Once an electronic device is identified or determined, an operation for searching for contents and displaying the determined contents may be triggered automatically without a search command as in the example of
The augmented remote controller 200 may display the locked contents on the display 260 after user authentication.
Upon input of a user authentication in operation S840, the controller 280 may control the locked contents by releasing or unlocking the contents in operation S850.
The identification unit 250 may recognize the voice, iris, finger print, and/or face of the user. Thus, the user authentication information may be information related to the recognized voice, iris, finger print, and/or face of the user that matches information about at least one of the pre-registered voice, iris, finger print, and/or face of the user.
The identification unit 250 may include a finger print reader for reading a finger print. If a finger print read by the finger print reader matches a pre-registered user's finger print, the controller 280 may release the locked contents (or unlock contents).
An augmented remote controller equipped with a finger print reader or a scanner may perform a user authentication operation in which a user's finger print is compared with a finger print that unlocks a locked content. As shown in
if the user captures a particular object or arranges objects in a predetermined layout using the augmented remote controller 200, the locked contents may be released.
The augmented remote controller may unlock the locked contents by recognizing the voice, iris, and/or predetermined gesture of the user.
In an exemplary embodiment, the augmented remote controller 200 may further include an audio I/O unit for receiving a voice signal or a sensor unit for sensing movement of the user or the augmented remote controller 200. The controller 280 may release the locked contents, when a received voice signal matches a pre-registered user's voice or when a gesture input created based on sensed movement information matches with a pre-registered user's gesture.
As shown in
The user authentication input may also be a password. The augmented remote controller may further include a user interface having an input device (e.g. a keypad) for allowing a user to enter a password. An input of a preset password may be the user authentication.
When a lock iron representing a locked status is touched or a predetermined input is received, a user authentication process may be triggered. As shown in
If the password entered through the virtual keyboard displayed on the display 260 or the keypad matches an unlocking password, then the locked content may be released (or unlocked).
In an exemplary embodiment, the identification unit 250 may include a camera for capturing a still image or a video. If the captured still image or video matches a still image or video of a preset object or a preset layout of a plurality of objects, then the locked content may be released (or unlocked).
As shown in
Additionally, the augmented remote controller 200 may release the locked content when an image of the face of the user captured by the camera matches a user's face registered for unlocking the locked content. The face matching may be determined by comparing a pattern of the recognized face with a pattern of the registered face.
If user information matches information that triggers unlocking of the locked content during the user authentication process, the augmented remote controller 200 may release the locked content and display information about the unlocked content on the display 260.
The information about the unlocked content may include a thumbnail image of the content, a title of the content, etc. As shown in
When thumbnails of unlocked contents are displayed on the display 260, the user may select one of the thumbnails and a content corresponding to the selected thumbnail may be played in a predetermined electronic device.
In an exemplary embodiment, the controller 280 may control the display 260 to display information regarding the unlocked content and may control the unlocked content to be played in the electronic device. That is, when the locked content is released, information regarding the content may be displayed. When the user later selects the content, the content may be played. Alternatively, as soon as the locked content is released, the content may be immediately played.
Referring to
User authentication may be requested based on a type of the electronic device. For example, different users may set their passwords and user authentication inputs for a plurality of storages so that only an authorized user can access information in the storages. Alternatively, an image display apparatus may be set to be accessible only when a user authentication is from a parent.
The image display apparatus 100 may be in a powered-off state or in a standby state. In this example, when the augmented remote controller 200 identifies or determines the image display apparatus 100 and a last content or channel viewed through the image display apparatus 100 has been set as locked or has a limit for viewing, the object 1001 representing the image display apparatus 100 may be augmented with the object 1011 indicating a locked status, as shown in
Referring to
Upon receipt of a proper user authentication input that triggers unlocking of a locked channel, the augmented remote controller 200 may display the channel and content information.
In a presence of a locked content from among the contents, information about the locked content may be augmented with an object 1019 indicating a locked status.
As shown in
That is, a user may be identified or determined by receiving a user authentication input. Thus, only contents for which the user is authorized may be displayed, and/or the other contents may be displayed in a limited manner, using an object indicating a locked status.
Registering a user authentication setting may further be performed. The user authentication setting may include user information, a user authentication input method, and/or a user access class.
The user authentication setting may include an appropriate user authentication method that can identify a user, aside from a user name or a user ID. For example, the finger print, iris and/or face of the user, and/or a photo of an object may be registered, and/or a password may be set.
Additionally, the user authentication setting may include a user access class. For example, if a user turns out to be a family member under the age that is allowed to access a content, the content may be locked or prevented from viewing.
The information regarding the contents may be displayed in a different manner according to the user authentication input in the content information display operation S2030. Thus, a personalized menu and personalized contents may be provided, a user's privacy may be protected, and the user may use appropriate contents.
In an exemplary embodiment, only information about contents allowed for the user according to the user authentication input may be displayed in operation S2030. Alternatively, in the presence of a content inaccessible to the user according to the user authentication input, an object indicating a locked status may be displayed in operation S2030, as shown in
Referring to
If an underage family member is subjected to the user authentication process, the information regarding the locked content may not be displayed as shown in
An image display apparatus or an external device connected to the image display apparatus can be controlled by use of a single remote controller. Additionally, a user can efficiently use and manage contents played or stored in the image display apparatus or the external device connected to the image display apparatus, and information related to the contents.
A safe and convenient locking and unlocking function and a privacy protection function may be implemented for contents playable in an electronic device, such as an image display apparatus or an external device. Individual users' tastes may be reflected and security may be ensured. Therefore, user convenience may be increased.
The method for operating the augmented remote controller may be implemented as code that can be written on a computer-readable recording medium and can thus be read by a processor. The computer-readable recording medium may be any type of recording device in which data is stored in a computer-readable manner. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disc, an optical data storage, and a carrier wave (e.g., data transmission through the internet). The computer-readable recording medium can be distributed over a plurality of computer systems connected to a network so that computer-readable code is written thereto and executed therefrom in a decentralized manner. Functional programs, code, and code segments needed for realizing the embodiments herein can be construed by one of ordinary skill in the art.
