In this case, a combination of one BSC and at least one BS may be referred to as a "base station ". The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS may be referred to as a plurality of cell sites.

A broadcast transmitter (BT) transmits a broadcast signal to the watch type mobile terminals (100) operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the watch-type mobile terminal 100. The satellite assists in locating the watch-type mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the watch-type mobile terminal 100 can be tracked using all the techniques capable of tracking the position as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmissions.

The position information module 115 included in the watch-type mobile terminal 100 detects, computes, or identifies the position of the mobile terminal, and includes a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module can do. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi positioning system (WPS) is a WiFi positioning system that uses a WiFi module included in the watch-type mobile terminal 100 and a wireless access point (wireless AP) that transmits or receives a wireless signal with the WiFi module, Is a technology for tracking the position of the terminal 100, and refers to a WLAN (Wireless Local Area Network) based positioning technology using WiFi.

The information of the wireless AP connected to the watch-type mobile terminal 100 may be transmitted to the Wi-Fi position location server through the watch-type mobile terminal 100 or may be transmitted from the wireless AP to the Wi-Fi position location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Thereafter, the Wi-Fi location server may extract (or analyze) location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The location information of the extracted mobile terminal 100 is transmitted to the mobile terminal 100 via the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

However, the present invention is not limited thereto, and the image reproducing device 350 may include various types of image source sources capable of reproducing images such as a laptop, a PC, and a display device. When the image reproducing device 350 is implemented as a laptop, a PC, a display device, or the like and is difficult to be mounted on the VR device 300, the image reproducing device 350 may be connected to the VR device 300 to reproduce have.

The video reproducing device 350 exchanges video signals and / or control signals with the VR device 300, and can perform various types of wired / wireless communication with the VR device 300. [

The watch-type mobile terminal 100 may control the VR device 300 or the video reproducing device 350. [

For this purpose, the watch-type mobile terminal 100 can perform various kinds of wired / wireless communication with the VR device 300 and / or the image reproducing device 350. According to one embodiment, the watch-type mobile terminal 100 can perform low-power Bluetooth low energy (BLE) communication with the VR device 300 and / or the image reproducing device 350.

When the user views the virtual content through the VR device 300, the user may attach the image reproducing device 350 directly to the VR device 300 or use the connected device with the VR device 300. Therefore, it is difficult for the user to control the VR device 300 or the image reproducing device 350 while the VR device 300 is worn.

According to the present invention, it is possible to easily control the VR device 300 and / or the image reproducing device 350 by the watch-type mobile terminal 100 when viewing virtual contents in cooperation with the watch-type mobile terminal 100 I will.

4A to 4C are diagrams illustrating various operations of a user recognized by a watch-type mobile terminal according to an exemplary embodiment of the present invention.

The watch-type mobile terminal 100 according to an exemplary embodiment of the present invention can recognize various operations performed by the wearer. The various operations of the user may include, but are not limited to, movements of arms and arms, shaking hands or arms, raising or lowering an arm, gripping or stretching a fist, holding an imaginary object with fingers in the air, A teaching operation, an operation for looking in a predetermined direction, and the like.

In this case, the watch-type mobile terminal 100 detects the operation of the watch-type mobile terminal 100 or the VR device 300 using at least one of a proximity sensor, an acceleration sensor, a gyro sensor, a muscle sensor, From this, it is possible to judge what operation the user performs. The watch-type mobile terminal 100 is worn on the user's wrist, and the VR device 300 is worn on the user's head. Therefore, the watch-type mobile terminal 100 can determine the operation performed by the user from the movement of the watch-type mobile terminal 100 or the VR device 300. [

Fig. 4A shows a case where different controls are performed depending on the degree to which the user extends his / her arms. The watch-type mobile terminal 100 may detect the degree to which the watch-type mobile terminal 100 is located close to or far from the user's body based on the proximity distance and the proximity direction to the user detected by the proximity sensor. Based on this, the watch-type mobile terminal 100 can determine whether the user performs an operation of pushing or extending an arm.

The space surrounding the user can be divided into a plurality of areas. The area is defined as a space within a range separated from the user by a predetermined distance from the user. In this case, the watch-type mobile terminal 100 can control the VR device 300 and / or the image reproducing device 350 based on which area the user extends the arm. Specifically, the user can control the VR device 300 and / or the image reproducing device 350 to select the content if the user extends his / her arm to a near area, and / or to select the folder when the user reaches the remote area.

Referring to FIG. 4A, the space surrounding the user is divided into Area 1 (Area 1), Area 2 (Area 2), and Area 3 (Area 3) according to the distance from the user. In this case, the watch-type mobile terminal 100 performs different control operations depending on which area the user extends his arm.

According to one embodiment, as the distance from the user increases, a control operation for controlling the upper menu may be assigned. For example, if you stretch your arms to Area 1, you execute content, and when you extend your arms to Area 2, you run the folder to which the content belongs. If you extend your arms to Area 3 (Area 3) You can run the app that the folder belongs to.

4B illustrates a method in which a user recognizes an operation of rocking the arm. The watch-type mobile terminal 100 can detect whether or not the user has shaken his or her arm based on the displacement and the acceleration sensed by the gyro sensor and the acceleration sensor. In the steady state where the user does not shake his arm, the displacement with respect to the position of the user's arm is small. On the other hand, in the state where the user shakes the arm, the displacement of the position of the user's arm changes rapidly with time. Based on this, the watch-type mobile terminal 100 can determine whether the user performs an operation of rocking the arm.

Referring to FIG. 4B, it can be determined that the user does not shake his / her arm in the X section and the user shakes his / her arm in the Y section.

4C illustrates a method of recognizing the movement of various fingers of a user. The watch-type mobile terminal 100 can recognize the motion of the user's finger based on the motion of the muscle sensed by the muscle sensor. In this case, it is possible to determine a predetermined operation performed by the user based on the movement pattern and the shape of the finger. The predetermined operation performed by the user may include, for example, a user's operation to hold or stretch a fist, the operation to hold a virtual object with a finger on the air, and the like.

In order to more accurately sense movement of the muscles, the muscle sensor may be included in the portion of the band 202 where the muscles of the arm abut.

As shown in FIG. 4C, when the user performs an operation such as grasping a fist, spreading a fist, or touching a finger to catch an object in the air, the movement of the muscles of the arms and fingers is different. Accordingly, the watch-type mobile terminal 100 can sense movement of the various muscles and determine the operation performed by the user.

Further, the watch-type mobile terminal 100 may determine various operations of the user based on the sensing information sensed by the at least one sensor. For example, the watch-type mobile terminal 100 may determine whether the user performs an operation of pointing a predetermined direction with a finger, based on the motion of the user's finger and arm sensed by the motion sensor. As another example, the watch-type mobile terminal 100 may determine whether the user performs an operation for looking in a predetermined direction, based on the movement of the VR device 300. [ For this purpose, the VR device 300 can detect movement of the corresponding VR device 300 and transmit the information to the watch type mobile terminal 100.

Hereinafter, various embodiments in which the virtual content can be easily and conveniently controlled through the watch-type mobile terminal when the user wears the VR device 300 and enjoy the virtual content will be described in detail.

Control of Virtual Contents by Watch Type Mobile Terminal

5 is a flowchart illustrating an operation of the watch-type mobile terminal according to an embodiment of the present invention.

The watch-type mobile terminal 100 according to an embodiment of the present invention can control the virtual content displayed by the VR device 300. [

The VR device 300 displays virtual contents based on an image reproduced by the image reproducing device 350, which is worn on the user's head. To this end, the VR device 300 is equipped with or connected to the image reproducing device 350 do. Because of this characteristic, it is difficult for the user to control the VR device 300 or the video reproducing device 350 in a situation where the VR device 300 or the video reproducing device 350 is out of sight.

Accordingly, in the present invention, when the user watches the virtual content through the VR device 300 while wearing the watch-type mobile terminal 100, the virtual content can be controlled by the watch-type mobile terminal 100 do.

As shown in FIG. 5, the watch-type mobile terminal 100 performs communication with the VR device 300 (S501).

According to one embodiment, the watch-type mobile terminal 100 can perform low-power Bluetooth communication with the VR device 300. [ However, the present invention is not limited thereto, and the communication performed by the watch-type mobile terminal 100 and the VR device 300 may include various types of wire / wireless communication methods.

In this case, the watch-type mobile terminal 100 communicates with the VR device 300 so that the VR device 300 can receive information about whether the video playback device 350 displays the virtual content based on the video being played back .

Meanwhile, the watch-type mobile terminal 100 may communicate with the video playback device 350 instead of the VR device 300. [ In this case, the watch-type mobile terminal 100 can perform low-power Bluetooth communication with the image reproducing apparatus 350, thereby acquiring information on whether the image reproducing apparatus 350 is reproducing an image.

The watch-type mobile terminal 100 determines whether the virtual content is being played back (S502).

According to one embodiment, when the watchdog mobile terminal 100 determines that the VR device 300 is reproducing the virtual content, it can automatically switch to the mode for controlling the virtual content.

Accordingly, if the watchdog mobile terminal 100 determines that the virtual content is being played back (S502-Yes), the watchdog mobile terminal 100 detects the movement of the user after switching to the mode for controlling the virtual content (S503).

To this end, the watch-type mobile terminal 100 detects the operation of the watch-type mobile terminal 100 or the VR device 300 using at least one of a proximity sensor, an acceleration sensor, a gyro sensor, a muscle sensor, From this, the motion of the user can be detected.

The watch-type mobile terminal 100 controls the virtual content (S504).

Specifically, the watch-type mobile terminal 100 may control the VR device 300 or the image reproducing device 350. In this case, the watch-type mobile terminal 100 can control the VR device 300 or the image reproducing device 350 in response to the motion of the user detected in step S503.

On the other hand, if it is not determined in step S502 that the virtual content is being reproduced (No in step S502), the watch-type mobile terminal 100 ends the procedure shown in FIG.

FIG. 6 is a diagram illustrating an example in which a watch-type mobile terminal performs a function of a controller for controlling virtual contents according to an embodiment of the present invention.

Since the virtual content is not only a three-dimensional image but also has a different viewing angle for each user, the focus of the virtual content needs to be adjusted according to the user. According to the present invention, the focus of the virtual content can be adjusted by the bezel 610 included in the watch-type mobile terminal 100.

The bezel 610 is rotatable with an outer rim portion surrounding the clock screen. The bezel 610 may correspond to the window 251a shown in Fig.

The bezel 610 can be rotated in both directions. In this case, the bezel 610 can be rotated in a clockwise or counterclockwise direction, and the focus of the virtual content can be focused on or focussed in response to a clockwise or counterclockwise rotation operation, respectively out.

In addition, the bezel 610 can be pushed or pulled in a vertical direction. In this case, the bezel 610 may be pushed downward or pulled upwards, and the focal point of the virtual content may be focused on or out of focus in response to each operation.

According to one embodiment, the focus adjustment function by the bezel 610 can be performed when the VR device 300 reproduces the virtual content. In this case, if the bezel 610 is rotated or pressed while the VR device 300 does not reproduce the virtual content, a control function other than the focus adjustment function can be executed.

On the left side of FIG. 6, virtual contents shown at the user's view through the VR device 300 are shown. In this case, the virtual content is blurred because it is out of focus. In this state, the user rotates the bezel 610 clockwise or counterclockwise to adjust the focus of the virtual content.

The right side of FIG. 6 shows the virtual contents viewed at the user's view through the VR device 300 after the focus is adjusted by the rotating operation of the bezel 610. In this case, the virtual content is clearly displayed after the focus correction is completed.

In this way, when the virtual contents are reproduced, the user can adjust the focus by rotating the bezel 610 of the watch-type mobile terminal 100 worn on the wrist in both directions. According to this, even if the user wears the VR device 300, the focal point of the virtual content can be adjusted immediately in a natural posture.

7A to 7C are views illustrating another example of a watch-type mobile terminal performing a function of a controller for controlling virtual contents according to an embodiment of the present invention.

Various functions relating to viewing of virtual contents need to be performed even after the virtual contents are selected or selected and executed. However, it is difficult for the user to perform such various functions through the VR device 300 or the video reproducing device 350 while viewing the virtual contents. Accordingly, in the present invention, various functions relating to viewing of virtual contents can be performed in place of the watch-type mobile terminal 100. [

Here, various functions related to viewing of the virtual contents may include execution of a gallery app, selection of a play item, playback, pause or stop, capture, rewind, or fast forward.

7A shows a case where an execution screen of a gallery app is controlled. When the gallery app is executed in the video reproducing device 350, an execution screen of the gallery app can be displayed. A list of videos that can be reproduced by the video reproducing apparatus 350 can be displayed on the execution screen of the gallery app.

The image list may include a plurality of images. The plurality of images may include at least one of an image and a moving image. In this case, each of the plurality of images is displayed as a representative thumbnail image, and can be arranged according to a predetermined reference.

Upon receiving the input signal for searching the image list, the watch-type mobile terminal 100 may control the image reproducing apparatus 350 to scroll and display a plurality of images included in the image list. According to an embodiment, the input signal for searching the image list may be a signal for sweeping the watch screen of the watch-type mobile terminal 100 in a predetermined direction. Here, the predetermined direction may be any one of a right side, a left side, an upper side, and a lower side.

Referring to FIG. 7A, an input signal for sweeping the image list to the right is received by the watch-type mobile terminal 100. In this case, the plurality of images 701, 702, and 703 are scrolled to the left, and the plurality of images 701, 702, and 703 included in the image list are moved to the left. At the same time, the image 704 displayed on the right side before the scrolling starts to be displayed on the screen.

Accordingly, the user can easily search a plurality of images included in the image list through the watch-type mobile terminal 100.

FIG. 7B shows a case where an arbitrary image is selected from the image list. When the watch-type mobile terminal 100 receives an input signal for selecting any one of a plurality of images included in the image list, the watch-type mobile terminal 100 can control the image reproducing device 350 to reproduce the selected arbitrary image. According to an embodiment, an input signal for selecting an arbitrary image may be a signal for tapping at any one point on the watch screen of the watch-type mobile terminal 100.

To this end, the watch screen of the watch-type mobile terminal 100 and the screen of the video reproducing apparatus 350 displaying the video list may correspond to each other. Specifically, when an input signal for tapping the right side of the watch screen of the watch-type mobile terminal 100 is received, a moving image located on the right side of the screen of the video reproducing apparatus 350 on which the video list is displayed can be selected. Also, when an input signal for tapping the left side of the clock screen is received, a video located on the left side of the screen on which the video list is displayed can be selected.

In this case, an identifier may be displayed on the screen of the image reproducing device 350 corresponding to the tapping point on the clock screen so that the user can recognize it.

Referring to FIG. 7B, an input signal for tapping the center portion of the watch-type display of the watch-type mobile terminal 100 is received. Correspondingly, among the plurality of images 702, 703, and 704 displayed on the screen of the image reproducing device 350, the image 703 displayed at the center portion is selected.

Accordingly, the user can easily select an arbitrary image among the plurality of images included in the image list through the watch-type mobile terminal 100.

FIG. 7C shows a case of controlling a screen during moving picture reproduction. When the VR device 300 displays the virtual content based on the image reproduced by the image reproducing device 350, the watch-type mobile terminal 100 displays the virtual content on the watch screen of the watch-type mobile terminal 100 The virtual content can be controlled based on various operations.

Upon receiving an input signal tapping a central portion of the watch screen, the watch-type mobile terminal 100 may control the VR device 300 or the video playback device 350 to reproduce or stop the video. Specifically, the watch-type mobile terminal 100 starts to reproduce an image when receiving an input signal that hits a center portion of the clock screen in a state that an image is selected, and receives an input signal that hits a center portion of the clock screen in a state in which the image is reproduced The image reproducing apparatus 350 can be controlled to stop the image.

Upon receiving the input signal for swiping the clock screen, the watch-type mobile terminal 100 can control the VR device 300 or the image reproducing device 350 to fast-forward or rewind the image. Specifically, the watch-type mobile terminal 100 rewinds the image when receiving an input signal that sweeps the screen to the left in a state in which the image is being reproduced. Upon receipt of an input signal for swiping the screen to the right in a state in which the image is being reproduced, the image reproducing apparatus 350 can be controlled to fast-forward the image.

Control of image reproduction device by spatial characteristics caused by wear of watch type mobile terminal

8A and 8B illustrate an example in which a watch-type mobile terminal according to an exemplary embodiment of the present invention performs a function of a controller for controlling an image reproducing apparatus.

The watch-type mobile terminal 100 according to an exemplary embodiment of the present invention can control an event occurring in the video reproducing apparatus 350 when the video reproducing apparatus 350 is mounted or connected to the VR apparatus 300 .

An event may be generated in the video reproducing apparatus 350 in a state where the video reproducing apparatus 350 is mounted on the VR apparatus 300. [ Here, the event may include origination or reception of a call, transmission or reception of a text message, reception of a notification message, and the like. In this case, since the image reproducing device 350 is mounted or connected to the VR device 350, it is difficult for the user to control the event occurring in the image reproducing device 350.

According to the present invention, when the video reproducing apparatus 350 is mounted or connected to the VR apparatus 300, an event occurring in the video reproducing apparatus 350 can be controlled through the watch-type mobile terminal 100.

Specifically, an event occurring in the image reproducing apparatus 350 can be controlled by an operation of a user wearing the watch-type mobile terminal 100. [ In this case, the operation of the user may be an operation of raising or lowering the arm wearing the watch-type mobile terminal 100, a stretching or pulling operation, a shaking operation, or the like. However, the present invention is not limited thereto, and the operation of the user may be variously set according to the embodiment.

Accordingly, the watch-type mobile terminal 100 can perform an event occurring in the image reproducing apparatus 350 instead.

On the other hand, in order to notify the user that an event has occurred, an icon representing an event that has occurred may be displayed on the screen of the virtual content being played back.

In FIG. 8A, a call reception event is generated in the video playback device 350 while the user is listening to the virtual content through the VR device 300.

When the arm is lowered, the watch-type mobile terminal 100 detects this and disconnects the connected phone. In this case, since the telephone conversation is ended, the telephone icon 810 disappears on the screen of the virtual contents.

9A to 9C are views showing another example in which a watch-type mobile terminal according to an embodiment of the present invention performs a function of a controller for controlling an image reproducing apparatus.

FIG. 9A shows a case in which the control operation varies depending on the distance. Specifically, the watch-type mobile terminal 100 can control the virtual content based on whether the movement in the space occurs at a distance from the user.

Referring to FIG. 9A, different regions 910 and 920 are defined according to the distance from the user. In this case, different kinds of control operations are assigned to the motion in the space generated in the different areas 910 and 920. Specifically, a single selection is assigned to the first area 910 nearest to the user, and multiple selection or folder selection can be assigned to the second area 920 far from the user. In this case, the user may extend his / her arm wearing the watch-type mobile terminal 100 to the first area 910 or the second area 920 for single selection or multiple selection (or folder selection) 920 by moving the arms up, down, left, and right to select, execute, or delete a single desired content or folder.

To this end, the space of the areas 910 and 920 and the screen on which a plurality of contents are displayed may correspond to each other. Specifically, when the arm is moved up and down and left and right in the regions 910 and 920, contents displayed at the upper, lower, left, and right positions among the plurality of contents can be selected.

FIG. 9B shows a case where the control operation is performed in the first region 910 close to the user. For a single selection of content, the user pulls his / her arm forward in the first area 910. In a state in which the user does not leave the first area 910, the user moves the arm up or down or left or right to select the content to be deleted. Referring to FIG. 9B, among the plurality of contents displayed on the screen, the content displayed at the bottom right is selected.

When a predetermined content is selected, an icon for asking whether to delete the selected content is displayed. In this case, the user moves his / her arm left and right without leaving the first area 910 to select a desired icon. Thereby, the selected content is deleted.

9C shows a case where the control operation is performed in the second area 920 far from the user. For multiple selection or folder selection of content, the user pulls his / her arm forward in the second area 920. In a state in which the second area 920 does not exit, the user moves the arm up or down or left or right to select a folder to be deleted. Referring to FIG. 9C, a folder displayed at the center among a plurality of folders displayed on the screen is selected.

When a folder displayed at the center is selected, an icon asking whether to delete the selected folder is displayed. In this case, the user moves his / her arm left and right without leaving the second area 920 to select a desired icon. Thereby, the selected folder can be deleted. On the other hand, the case of multiple selection may be similarly performed.

10A and 10B are views illustrating another example of a controller of a watch-type mobile terminal according to an exemplary embodiment of the present invention.

The watch-type mobile terminal 100 can control an app executed in the image reproducing apparatus 300 based on whether a motion in space has occurred at a distance from the user.

Specifically, when the watch-type mobile terminal 100 performs an operation of shaking the arm in a region close to the user, the watch-type mobile terminal 100 controls the video playback device 350 to display a detailed menu item for the execution screen or content of the app. Referring to FIG. 10A, when the gallery application is executed and predetermined contents are displayed, the user shakes his arm wearing the watch-type mobile terminal 100 in the first area 910. In this case, a submenu item 1010 for the content is displayed at the bottom of the screen.

On the other hand, when the watch-type mobile terminal 100 performs an operation to shake the arm in a region far from the user, the watch-type mobile terminal 100 controls the image playback device 350 to move to the upper menu or the home screen of the corresponding content or app. Referring to FIG. 10B, the user shakes his arm wearing the watch-type mobile terminal 100 in the second region 920. In this case, a plurality of folders included in the upper menu are displayed by moving to the upper menu of the corresponding content.

Control of virtual content by NUI

11 is a diagram illustrating an example in which a watch-type mobile terminal according to an embodiment of the present invention controls virtual contents by NUI.

The virtual content displayed by the VR device 300 can be controlled by a Natural User Interface (NUI).

The NUI may be a UI that recognizes the natural movement of the user and provides information exchanged with each other. Such an NUI can be controlled not only by a control operation by an operating device such as a keyboard or a mouse but also by a control operation by the user's body such as multi-touch, pressure touch, and 3D motion recognition.

The control operation defined in the NUI may be an operation unconsciously performed by the user while listening to the virtual content. Specifically, when the user wears the VR device 300 and watches the virtual content, the user's motion is automatically generated according to the content of the virtual content to be played back. For example, the user may unconsciously move his / her hand, point to a predetermined direction, or perform an operation of capturing a content screen as the screen of the virtual content is moved or reproduced.

According to the present invention, the virtual content can be controlled according to a control operation performed by the user unconsciously. In this case, the user views the virtual content through the VR device 300. [ So that natural interaction with the virtual content can be performed.

According to one embodiment, the virtual content may be zoomed in or out based on the user's action of stretching or pulling an arm or pushing or pulling the body forward or backward. Specifically, the virtual content is zoomed in when the user stretches his arms or pushes forward, and the virtual content can be zoomed out when the user pulls his arm toward his body or backs his body.

The user unknowingly reaches out to the virtual content by stretching his arms or pushing forward to see the virtual contents more closely. Accordingly, when the user extends his or her arms or moves forward, the watch-type mobile terminal 100 can control the VR device 300 or the image reproducing device 350 to zoom in the virtual content.

On the other hand, the user unconsciously pulls the arm toward the body or pulls it backward to move away from the virtual content in order to watch the virtual contents from afar as a whole. Accordingly, when the user pulls the arm to the body or pulls the body back, the watch-type mobile terminal 100 can control the VR device 300 or the video playback device 350 to zoom out the virtual content.

Referring to FIG. 11, when a user extends the arm wearing the watch-type mobile terminal 100 forward, the virtual content is zoomed in. Thereby, the virtual contents are enlarged and displayed in detail. On the other hand, even if the virtual content is a game app or a space experience app, it is possible to control the virtual content such that the entire space is zoomed in or out according to the operation of extending or pulling the arm or the user's view is moved forward or backward on the screen .

12 is a diagram illustrating another example in which a watch-type mobile terminal according to an embodiment of the present invention controls virtual contents by NUI.

The watch-type mobile terminal 100 according to an embodiment of the present invention can control the virtual content based on the operation of the user wearing the VR device 300. [ Specifically, the watch-type mobile terminal 100 can control the virtual content based on at least one of the operation and the direction of operation of the user.

According to one embodiment, the virtual content can be selected or played based on the direction the user is viewing. Specifically, when the user moves the head, the virtual content displayed in the moving direction can be selected or reproduced.

The user unconsciously looks at the virtual content desired to be viewed. Accordingly, when the user moves the head in a predetermined direction, the watch-type mobile terminal 100 can control the VR device 300 or the video reproducing device 350 to select or reproduce the virtual content corresponding to the user's line of sight .

In this case, the watch-type mobile terminal 100 can recognize the operation of the user wearing the VR device 300 based on the movement of the VR device 300. [ Here, the operation of the user may include an operation of looking in a predetermined direction, an operation of moving the head in a predetermined direction, an operation of shaking the head up and down, and the like. For example, if the viewing angle of the VR device 300 is deviated from the front by a predetermined angle, the watch-type mobile terminal 100 may determine that the user performs an operation for looking in a predetermined direction. If the VR device 300 repeatedly moves in the vertical direction, the watch-type mobile terminal 100 may determine that the user performs an operation of shaking the head.

To this end, the watch-type mobile terminal 100 may communicate with the VR device 300 and receive information about the movement of the VR device 300. [ In this case, the VR device 300 may include a motion recognition sensor to sense movement of the VR device 300 corresponding to the movement and direction of the user's head.

The area on the space where the user moves the head can be associated with the screen on which the virtual content is displayed. Thus, in each case where the user moves the head left or right in space or faces the front, the corresponding region of the virtual content can be selected.

Referring to FIG. 12, a user wearing the VR device 300 moves the head portion to the left in the space. The movement and direction of the user is detected by the VR device 300, and the VR device 300 transmits the sensed information to the watch-type mobile terminal 100.

The watch-type mobile terminal 100 controls the video reproducing apparatus 300 to select an image displayed in an area of a virtual content corresponding to a left region of the space. Thereby, the user can unconsciously move the line of sight and select an image positioned in the direction in which the user looks. In Fig. 12, the image displayed on the left side on the virtual content is selected and displayed corresponding to the movement of the user looking left.

FIG. 13 is a diagram illustrating another example in which a watch-type mobile terminal according to an embodiment of the present invention controls virtual contents by NUI.

The watch-type mobile terminal 100 may perform a zoom-in or zoom-out function on a space included in the virtual contents, based on the NUI control operation performed by the user unconsciously viewing the virtual contents.

In the virtual content, an image reproduced by the image reproducing device 350 is displayed as a three-dimensional image, and virtual objects may be superimposed on the upper and lower layers of the three-dimensional image.

According to one embodiment, the virtual content can be zoomed in or out based on an operation of a user capturing a three-dimensional image and pulling it forward or extending an arm and pushing it back. Specifically, when a user captures a 3D image and pulls it toward the front, the virtual content is zoomed in. If the user extends his arm and pushes the 3D image backward, the virtual content can be zoomed out.

The user unconsciously grabs the 3D image and pulls it forward to watch the 3D image included in the virtual content in more detail. Accordingly, when the user captures and drags the 3D image, the watch-type mobile terminal 100 can control the VR device 300 or the image reproducing device 350 to zoom in the virtual content. On the other hand, as the virtual content is zoomed in, additional information is further displayed on the virtual content and can be provided to the user.

On the other hand, a user unknowingly stretches his arms and pushes back three-dimensional images to view virtual contents from afar as a whole. Accordingly, the watch-type mobile terminal 100 can control the VR device 300 or the image reproducing device 350 to zoom out the virtual content when the user extends his arm and pushes the three-dimensional image backward.

In Fig. 13, the user holds the three-dimensional image included in the virtual content and pulls it forward. Thereby, the virtual contents are zoomed in, and the three-dimensional image is enlarged and displayed.

14A and 14B are diagrams illustrating another example in which the watch-type mobile terminal according to the embodiment of the present invention controls virtual contents by the NUI.

The execution screen of the application can be moved to the upper menu or moved to the lower menu based on the user's operation of stretching or pulling the hand. Specifically, when the user performs the operation of extending the hand, the execution screen of the application moves to the upper menu, and when the user performs the operation of pulling the hand, the execution screen of the application can move to the lower menu. 14A and 14B, the description of FIG. 14A and FIG. 14B may be applied to other applications executed by the image reproducing apparatus 350. [0156] FIG.

To return to the upper menu without further processing the running screen, the user unconsciously stretches the running screen and pushes it backwards. Accordingly, when the user reaches out and pushes the execution screen backward, the watch-type mobile terminal 100 can control the video reproduction device 350 to switch to the upper menu screen.

Referring to FIG. 14A, an execution screen of a gallery app displaying predetermined contents is displayed. In this state, the user stretches his hand to push the execution screen backward to return to the upper menu. Thus, the execution screen of the gallery app is switched to the upper menu screen in which the entire contents list is displayed.

To proceed to a running screen and enter a submenu, the user unconsciously grabs the execution screen and pulls it forward. Therefore, when the user holds the predetermined content among the plurality of contents displayed on the execution screen or the execution screen by hand and pulls it to the front, the watch-type mobile terminal 100 enters the submenu of the execution screen or executes and displays the selected contents. Referring to FIG. 14B, the user holds the predetermined content on the upper menu screen displayed with the entire contents by hand and pulls it forward. In this case, predetermined contents are executed and displayed.

FIG. 15 is a diagram illustrating another example in which a watch-type mobile terminal according to an embodiment of the present invention controls virtual contents by NUI.

When the user viewing the virtual content performs an operation of capturing a screen at a predetermined time point, the watch-type mobile terminal 100 may control the image reproducing apparatus 300 to capture the screen at that time point as an image. In this case, the captured image may be temporarily displayed at the bottom of the screen of the virtual content so that the user can check it.

When the user desires to capture a screen at a predetermined point in time, the user can unconsciously hold the screen by hand.

In FIG. 15, the user takes a gesture to slightly grasp the screen with the hand wearing the watch-type mobile terminal 100 while listening to the virtual content. In this case, the screen at that point in time is captured. The captured image is temporarily displayed at the bottom of the screen of the virtual content.

After a lapse of a predetermined time, the user again takes a gesture to slightly grasp the screen with the hand wearing the watch-type mobile terminal 100. In this case, the screen at that point in time is captured and displayed at the bottom of the screen of the virtual content.

It is difficult to capture desired scenes because there is a limitation of view while viewing virtual contents and hand is inconvenient. However, the user can perform capturing of the image reproduced by the image reproducing device 350 with a simple and simple operation.

Meanwhile, the NUI described above can be variously modified according to the embodiment as long as it corresponds to an operation unconsciously performed by a user with an intention to perform a certain function. For example, if the user wears the watch-type mobile terminal 100 and flips the palm down, the user can refuse to receive the call. You can also lower your volume by moving your finger up to increase the volume or moving your finger down. In addition, when the user unfolds the palm of the hand, the watch-type mobile terminal 100 can perform relocation of the virtual content displayed in the current user's view.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
