FIG. 1 is a block diagram illustrating the configuration of a glass-type mobile terminal 100 according to an embodiment of the present invention. Referring to FIG. 1, the glass-type mobile terminal 100 is shown having components such as a wireless communication unit 110, an input unit 120, a sensing unit 140, an output unit 150, an interface unit 160, a memory 170, a controller 180, and a power supply unit 190. Implementing all of the illustrated components is not a requirement, and that greater or fewer components may alternatively be implemented.
Referring now to FIG. 1, the wireless communication unit 110 typically includes one or more modules which permit communications such as wireless communications between the glass-type mobile terminal 100 and a wireless communication system, communications between the glass-type mobile terminal 100 and another mobile terminal, communications between the glass-type mobile terminal 100 and an external server. Further, the wireless communication unit 110 typically includes one or more modules which connect the glass-type mobile terminal 100 to one or more networks.
To facilitate such communications, the wireless communication unit 110 includes one or more of a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short-range communication module 114, and a location information module 115.
The input unit 120 includes a camera 121 for obtaining images or video, a microphone 122, which is one type of audio input device for inputting an audio signal, and a user input unit 123 (for example, a touch key, a push key, a mechanical key, a soft key, and the like) for allowing a user to input information. Data (for example, audio, video, image, and the like) is obtained by the input unit 120 and may be analyzed and processed by controller 280 according to device parameters, user commands, and combinations thereof.
The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor. Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image.
The sensing unit 140 is typically implemented using one or more sensors configured to sense internal information of the mobile terminal, the surrounding environment of the mobile terminal, user information, and the like. For example, in FIG. 1, the sensing unit 140 is shown having a proximity sensor 141 and an illumination sensor 142. If desired, the sensing unit 140 may alternatively or additionally include other types of sensors or devices, such as a touch sensor, an acceleration sensor, a magnetic sensor, a G-sensor, a gyroscope sensor, a motion sensor, an RGB sensor, an infrared (IR) sensor, a finger scan sensor, a ultrasonic sensor, an optical sensor (for example, camera 121), a microphone 122, a battery gauge, an environment sensor (for example, a barometer, a hygrometer, a thermometer, a radiation detection sensor, a thermal sensor, and a gas sensor, among others), a chemical sensor (for example, an electronic nose, a health care sensor, a biometric sensor, and the like), a heart rate detecting sensor, a sensor for sensing brain waves indicative of a user's emotion state, and a sensor (electronic patch) for sensing shivering of muscles (or skin). The glass-type mobile terminal 100 may be configured to utilize information obtained from sensing unit 140, and in particular, information obtained from one or more sensors of the sensing unit 140, and combinations thereof.
The output unit 150 is typically configured to output various types of information, such as audio, video, tactile output, and the like. The output unit 150 is shown having at least one of a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154. The display unit 151 may have an inter-layered structure or an integrated structure with a touch sensor in order to facilitate a touch screen. The touch screen may provide an output interface between the glass-type mobile terminal 100 and a user, as well as function as the user input unit 123 which provides an input interface between the glass-type mobile terminal 100 and the user.
The interface unit 160 serves as an interface with various types of external devices that can be coupled to the glass-type mobile terminal 100. The interface unit 160, for example, may include any of wired or wireless ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, and the like. In some cases, the glass-type mobile terminal 100 may perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 160.
The memory 170 is typically implemented to store data to support various functions or features of the glass-type mobile terminal 100. For instance, the memory 170 may be configured to store application programs executed in the glass-type mobile terminal 100, data or instructions for operations of the glass-type mobile terminal 100, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the glass-type mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the glass-type mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the glass-type mobile terminal 100, and executed by the controller 280 to perform an operation (or function) for the glass-type mobile terminal 100.
The controller 180 typically functions to control overall operation of the glass-type mobile terminal 100, in addition to the operations associated with the application programs. The controller 180 can provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1, or activating application programs stored in the memory 170. As one example, the controller 180 controls some or all of the components illustrated in FIG. 1 according to the execution of an application program that have been stored in the memory 170.
The power supply unit 190 can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the glass-type mobile terminal 100. The power supply unit 190 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.
At least part of the above components may cooperate with each other, so as to control an operation of a glass-type mobile terminal according to various embodiments to be explained later. A method of controlling a glass-type mobile terminal may be implemented on the mobile terminal, by driving at least one application program stored in the memory 170.
FIG. 2 is a perspective view illustrating one example of a glass-type mobile terminal 200 according to an embodiment. The glass-type mobile terminal 200 can be wearable on a head of a human body and provided with a frame 201 (case, housing, etc.) therefor. The frame may be made of a flexible material to be easily worn. The frame of glass-type mobile terminal 200 is shown having a first frame and a second frame, which can be made of the same or different materials.
The frame 201 may be supported on the head and defines a space for mounting various components. As illustrated, electronic components, such as a controller 280, a power supply unit 290 and an audio output module, may be mounted to the frame 201. Also, a lens 203 for covering either or both of the left and right eyes may be detachably coupled to the frame.
The controller 280 controls various electronic components disposed in the glass-type mobile terminal 200. The control module 280 may be understood as a component corresponding to the aforementioned controller 180. FIG. 2 illustrates that the controller 280 is installed in the frame part on one side of the head, but other locations are possible.
The display unit 251 may be implemented as a head mounted display (HMD). The HMD refers to display techniques by which a display is mounted to a head to show an image directly in front of a user's eyes. In order to provide an image directly in front of the user's eyes when the user wears the glass-type mobile terminal 200, the display unit 251 may be located to correspond to either or both of the left and right eyes. FIG. 2 illustrates that the display unit 251 is located on a portion corresponding to the right eye to output an image viewable by the user's right eye.
The display unit 251 may project an image into the user's eye using a prism. Also, the prism may be formed from optically transparent material such that the user can view both the projected image and a general visual field (a range that the user views through the eyes) in front of the user. In such a manner, the image output through the display unit 251 may be viewed while overlapping with the general visual field. The glass-type mobile terminal 200 may provide an augmented reality (AR) by overlaying a virtual image on a realistic image or background using the display.
The camera 221 may be located adjacent to either or both of the left and right eyes to capture an image. Since the camera 221 is located adjacent to the eye, the camera 221 can acquire a scene that the user is currently viewing.
The glass-type terminal 200 may be configured to further include a camera disposed close to one of left and right eyes to detect a user's eyeline (the left or right eye) and a user's facial expression. Hereinafter, such a camera for detecting a user's eyeline and facial expression will be named and referred to as a second camera.
In the drawings, the camera 221 is provided at the controller 280. However, the present invention is not limited to this. The camera 221 may be positioned at the frame, or multiple cameras may be utilized. Such multiple cameras may be used to acquire a stereoscopic image.
The glass-type mobile terminal 200 may include the user input unit 223, which can each be manipulated by the user to provide an input. The user input unit 223 may employ techniques which permit input via a tactile input. Typical tactile inputs include a touch, push, or the like. The user input unit 223 is shown operable in a touching manner as it is located on the frame. If desired, glass-type mobile terminal 200 may include a microphone which processes input sound into electric audio data.
The glass-type mobile terminal 200 may include an audio output module for outputting audio. The audio output module may be configured to produce audio in a general audio output manner or an osteoconductive manner. When the audio output module is implemented in the osteoconductive manner, the audio output module may be closely adhered to the head when the user wears the glass-type mobile terminal 200 and vibrate the user's skull to transfer sounds. In this instance, the audio output module may be provided at the same insertion part as that of the microphone.
Hereinafter, a glass-type terminal and a method for controlling the same will be explained, the method including detecting a user's emotion information and/or a user's linguistic expression information on an interest object, automatically capturing an image (an interest image) corresponding to the interest object based on the user's emotion information and/or the user's linguistic expression information, and providing (sharing) the interest image, and the interest information including the user's emotion information and/or the user's linguistic expression information so that the user may confirm and/or share not only the interest image, but also the emotion information and the linguistic expression information on the interest information.
FIG. 3 is a flowchart illustrating a control method according to an embodiment of the present invention. First, a detecting unit detects real time user's emotion information and user's linguistic expression information on an interest object (S31). The detecting unit may include a second camera configured to capture a user's facial expression (for instance, smiley, angry and sad expressions) on the interest object; a recognition unit configured to recognize the facial expression captured through the second camera; and a microphone configured to receive a voice corresponding to a user's utterance on the interest object. The recognition unit is configured to output to the controller 280 as a user's emotion information on the interest object, a model matching the captured facial expression (for instance, smiley expression) among preset expression models corresponding to the user's various facial expressions. The controller 280 recognizes a voice (for instance, wow!, good and the like) on the interest object received through the microphone 122 as a user's linguistic expression information.
The controller 280 can turn on the camera 221 when the user's emotion information and/or the user's linguistic expression information is detected (S32), and automatically capture an image corresponding to the interest object through the camera (S33). For instance, the controller 280 can capture, through the camera 221, an image (an interest image) corresponding to the interest object, e.g., a product, a building, a person and a signboard. The image corresponding to the interest object may be a still image or a video.
The controller 280 can be configured to turn on the camera 221 when the user's emotion information and/or the user's linguistic expression information is detected, and capture through the camera 221 a person who is on the current position or an owner of a peripheral device as the interest information.
The controller 280 can be configured to automatically capture an image corresponding to the interest object through the camera 221 when the camera 221 focuses on the interest object for a preset time (for instance, 2-3 seconds). The preset time (2-3 seconds) may be changed by the user or a designer's intention. The focal point of the camera 221 may be the same as or similar to the user's eyeline. The controller 280 can be configured to detect a user's gazing time at the interest object and to store the detected gazing time to a memory 170 together with the image corresponding to the interest object.
The controller 280 can be configured to detect a user's facial expression, which has been captured before and/or after based on a time point of capturing an image corresponding to the interest object, as the user's emotion information. The controller 280 can be configured to detect a user's facial expression, which has been captured at a time point of capturing an image corresponding to the interest object, as the user's emotion information.
The controller 280 can be configured to detect a user's utterance, which has been input before and/or after based on a time point of capturing an image corresponding to the interest object, as the user's linguistic expression information. For instance, the controller 280 can be configured to detect a user's utterance, which has been input through the microphone 122, ten seconds ago or ten seconds later, based on a time point of capturing an image corresponding to the interest object, as the user's linguistic expression information. The controller 280 can be configured to detect a user's utterance, which has been input through the microphone 122, from ten seconds ago to ten seconds later, based on a time point of capturing an image corresponding to the interest object, as the user's linguistic expression information.
The controller 280 can be configured to convert a user's utterance, which has been input through the microphone 122 before and/or after based on a time point of capturing an image corresponding to the interest object, into a text, and detect the text as the user's linguistic expression information. The controller 280 can be configured to turn on the camera 221 at predetermined time periods, and when the user's emotion information and/or the user's linguistic expression information on the interest object is detected while the camera 221 is turned on, automatically capture the image corresponding to the interest object.
The controller 280 can be configured to turn on the camera 221, when a user's input (for instance, a user's utterance, a facial expression (facial muscles), a button operation of a glass-type terminal, a user's gesture, a head movement, a touch input and the like) is received, and to capture an image corresponding to the interest object through the camera 221, when the user's emotion information and/or the user's linguistic expression information on the interest object is detected while the camera 221 is turned on.
The controller 280 can be configured to capture an image corresponding to the interest object through the camera 221 when the user's emotion information and/or the user's linguistic expression information on the interest object is detected, when the current position is a position that has been recorded in a schedule (a message, a messenger, a calendar, a map and the like). For instance, the controller 280 can be configured to automatically turn on the camera 221 when the user's emotion information (for instance, smiley facial expression) and/or the user's linguistic expression information on the interest object (for instance, a latest model phone) is detected, when the current position is a position that has been recorded in a schedule (for instance, an electronic appliances shop), and capture an image corresponding to the interest object through the camera 221. The user's linguistic expression information may be a user's voice accompanied by an exclamation (or designator) such as “Wow! It's a wonderful phone” and the like. The exclamation may be “Oh”, “Wow” and the like. The designator may be a pre-designated word such as “Take a picture!” and the like.
The controller 280 can be configured to capture an image corresponding to the interest object through the camera 221 when the user's emotion information and/or the user's linguistic expression information on the interest object is detected, when the current position is one of bookmarked places. For instance, the controller 280 can be configured to automatically turn on the camera 221 when the user's emotion information and/or the user's linguistic expression information on the interest object is detected, when the current position is one of bookmarked places (for instance, A Mart), and capture an image corresponding to the interest object through the camera 221.
The controller 280 can be configured to automatically capture an image corresponding to the interest object through the camera 221, when a user's emotion information and/or a user's linguistic expression information on the interest object is detected, when the current position and time have been recorded in the schedule. For instance, the controller 280 can be configured to automatically capture an image corresponding to the interest object through the camera 221, when a user's emotion information and/or a user's linguistic expression information on the interest object is detected, when the current position and time have been recorded in the schedule (for instance, A Coffee Shop, 13:00 p.m.).
The controller 280 can be configured to turn on the camera 221, when a Near Field Communication (NFC) tag, or Radio Frequency Identification (RFID) information for turning on the camera 221 is received through a near field communication module 114, and capture an image corresponding to the interest object when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on. The controller 280 can be configured to turn on the camera 221 when information for turning the camera 221 is received from an adjacent device through a near field communication module (for instance, Bluetooth), and capture an image corresponding to the interest object when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on.
The controller 280 can be configured to turn on the camera 221 when information for turning on the camera 221 is received from a server through a radio communications network, and capture an image corresponding to the interest object when a user's emotion information and/or a user's linguistic expression information on the interest object is received while the camera 221 is turned on.
The controller 280 can be configured to turn on the camera 221 based on a user's gesture (for instance, a user's gesture using hands (or fingers) or a user's head movement (for instance, a user's head movement in up, down, left and right directions, and a gradient of a user's head), and capture an image corresponding to the interest object through the camera 221 when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on. For instance, the controller 280 can be configured to detect a user's head movement through one of a motion sensor, a gyro-sensor, a geomagnetic field sensor, or a combination thereof, and turn on or turn off the camera 221 based on the head movement.
The controller 280 can be configured to turn on the camera 221 when a user's voice for controlling the operation (turn-on or turn-off) of the camera 221 is received (recognized), and capture an image corresponding to the interest object through the camera 221 when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on. For instance, the controller 280 can be configured to turn on the camera 221 when a user's voice of “camera operation,” is recognized, and capture an image corresponding to the interest object through the camera 221 when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on.
The controller 280 can be configured to turn on the camera 221 in accordance with a pause time at the current position, and capture an image corresponding to the interest object through the camera 221 when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on. For instance, the controller 280 can be configured to turn on the camera 221 when a user gazes at a “A Coffee Shop” which is the current position for one minute, and capture an image corresponding to the interest object through the camera 221 when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on. The controller 280 can be configured to turn off the camera 221 when the user moves from the “A Coffee Shop” which is the current position. The set time is not limited to one minute, and may be changed by the user or a designer's intention.
The controller 280 can be configured to turn on the camera 221 based on one or more than two of a user's facial expression, eye blink, biological signal (for instance, heart rate, trembling of skin (or muscles), and brain waves indicative of a user's feeling state), and capture an image corresponding to the interest object through the camera 221 when a user's emotion information and/or a user's linguistic expression information on the interest object is detected while the camera 221 is turned on. For instance, the controller 280 can be configured to detect a user's facial expression through the second camera disposed toward the user's face, and turn on or turn off the camera 221 based on the detected facial expression.
The controller 280 can be configured to detect a user's eye blink through the second camera disposed toward the user's face, turn on the camera 221 when the number of blinks is a first preset number (for instance, three times), and turn off the camera 221 when the number of blinks is a second preset number (for instance, four times). The first and second preset numbers are not limited to the above mentioned numbers, and may be changed by a user or designer's intention. The controller 280 can be configured to detect a user's heart rate through a sensor for sensing a heart rate, turn on the camera 221 when the detected heart rate exceeds or is less than a reference value (for instance, 20 mm Hg/80 mm Hg), and turn off the camera 221 when the detected heart rate is equal to or similar to the reference value (for instance, 120 mm Hg/80 mm Hg). The reference value (for instance, 120 mm Hg/80 mm Hg) is not limited, and may be changed by a user or designer's intention.
The controller 280 can be configured to propose to share an image corresponding to the interest object, and interest information including a user's emotion information and a user's linguistic expression information. For instance, the controller 280 can be configured to display on the display unit 151, a window (for instance, a popup window) proposing to share the interest image, and the interest information including the user's emotion information and the user's linguistic expression information when capturing the image is terminated, the interest object is out of the camera's angle of view, or the current position of the glass-type terminal is changed, and transmit (upload) to share the interest information to the SNS (Social Networking Service) server when a user's input to request to share the interest information (for instance, a user's gesture, a user's head movement, a user's voice command, a touch input, a physical input (for instance, button operations and the like) is received.
The controller 280 can be configured to display the interest information on the display unit 151 when sharing of the interest information is proposed. The controller 280 can be configured to transmit the interest information to a corresponding server using one or more of a Short Networking Service (SNS), a Short Message Service (SMS), a Long Message Service (LMS) and a Multi Message Service (MMS) when a user's input to request to transmit the interest information (for instance, a user's gesture, a user's head movement, a user's voice command, a touch input, a physical input (for instance, button operations and the like) is received.
Whenever the image corresponding to the interest object is captured, the controller 280 can be configured to store, in a memory 170, plural interest information including each captured image, and a user's emotion information and linguistic expression information on each interest object. The plural interest information stored in the memory 170 may be displayed on the display unit 251 or may be transmitted to a corresponding server using one or more of the Short Networking Service (SNS), a Short Message Service (SMS), a Long Message Service (LMS), and a Multi Message Service (MMS) according to the user's request.
FIG. 4 is a view illustrating interest information according to an embodiment of the present invention. As shown in FIG. 4, the controller 280 can display on the display unit 251, an image (4-1) corresponding to the interest object, and interest information including a user's emotion information (4-2) and a user's linguistic expression information (4-3) when a user's input is received, capturing an image is terminated, the interest object is out of the camera's angle of view, or the current position of the glass-type terminal is changed. For instance, the controller 280 can capture a phone image (4-1) corresponding to the interest object when the user's eyeline is toward the interest object (for instance, phone), and display on the display unit 251, the user's emotion information and the user's linguistic expression information (for instance, wow, good and the like) detected based on a capturing point of the phone image (4-1), as interest information. The user's emotion information (4-2) may include one or more of a character, an icon, an emoticon, a still image, and a moving image corresponding to the user's emotion information.
The interest information may further include a current position, a weekday, a date, and time information (4-4). For instance, the controller 280 can acquire a current position, a weekday, a date and time information when capturing the image (4-1) corresponding to the interest object, and display the acquired current position, the weekday, the date and the time on the display unit 251 together with the interest information, or transmit the acquired current position, the weekday, the date and the time to the corresponding server (for instance, an SNS server) together with the interest information.

Hereinafter, another method of selecting interest information to be uploaded (transmitted) to a corresponding server will be described with reference to FIGS. 8A and 8B. In particular, FIGS. 8A and 8B are views illustrating another method to select interest information to be uploaded (transmitted) to a corresponding server according to an embodiment of the present invention.
As shown in FIG. 8A, assuming a glass-type terminal 200 includes a first display unit (151-1) and a second display unit (151-2) which are disposed to correspond to the left and right eyes, respectively, the controller 280 can display plural interest information (8-1, 8-2 and 8-3) at the center of a timeline in response to a user's request according to interest information acquisition time, select specific interest information (8-2) among the plural interest information in response to a first user's input (for instance, the user's gesture, a user's voice, a head movement, a touch input, a button operation and the like), and display the selected specific interest information (8-2) on a first display unit (151-1) as a candidate group to be uploaded to a corresponding server when a second user's input (for instance, a head movement from the right to the left) is received.
As shown in FIG. 8B, assuming a glass-type terminal 200 includes a first display unit (151-1) and a second display unit (151-2) which are disposed to correspond to the left and right eyes, respectively, the controller 280 can display plural interest information (8-1, 8-2 and 8-3) at the center of a timeline of the second display unit (151-2) in response to a user's request according to interest information acquisition time (for instance, a user's gazing time and a time duration to stay at a corresponding position), and can display the attribute information (for instance, a data capacity of the specific interest information (8-2), a reproducing time of video, the number of images and the like) of the selected specific interest information (8-2) on the first display unit (151-1) and/or the second display unit (151-2) when the specific interest information is selected among the plural interest information in response to a first user's input (for instance, a user's gesture, a user's voice, a head movement, a touch input, a button operation and the like) is selected.
The controller 280 can change differently a display time of each of the plural interest information (or plural interest images) (8-1, 8-2 and 8-3) displayed on the timeline in the order of interest. For instance, the controller 280 can display the first interest information (8-1) on the second display unit (151-2) for ten seconds when a user's gazing time at an interest image included in the first interest information (8-1) among the plural interest information (8-1, 8-2 and 8-3) displayed on the timeline, is ten seconds, and may be configured to display the second interest information (8-2) on the second display unit (151-2) for three seconds when a user's gazing time at an interest image included in the second interest information (8-2) is three seconds. The display time of the plural interest information (8-1, 8-2 and 8-3) may be changed according to a user or designer's intention.
The controller 280 can guide to autofocus on one or more recommended interest information among the plural interest information (8-1, 8-2 and 8-3) or enlarge the recommended interest information so as to recommend in advance the interest information to be uploaded (shared). A condition to recommend a specific interest image among the plural interest information or images (8-1, 8-2 and 8-3) may include one of a user's gazing time at the interest image, a composition of the interest image, a brightness of the interest image, a resolution of the interest image, a high heart rate when capturing the interest image, brain waves in response to an emotional condition (for instance, good, discomfort and the like) when capturing the interest image, and the like, or a combination thereof.
The controller 280 can display two or more most recommended interest images among the recommended interest images in an enlarged manner. Thus, a user can select the recommended interest images, or move to other items (for instance, an interest image other than the recommended interest images, emotion information, a user's linguistic expression information and the like) to select a desired item therefrom. For instance, the controller 280 can select a user's desired recommended interest image or a user's desired item based on a head movement leaning in the left or right direction, a motion of facial muscles, a user's voice, a motion to gaze at an interest image other than the recommended interest image, etc.
