Meanwhile, as described above, the control unit 280 controls an operation related to an application program and an overall operation of the mobile terminal 200. [ For example, when the state of the mobile terminal satisfies a set condition, the control unit 280 can execute or release a lock state for restricting input of a user's control command to applications.
In addition, the control unit 280 performs control and processing related to voice communication, data communication, video call, or the like, or performs pattern recognition processing capable of recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively .

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.
Meanwhile, in the mobile terminal 200 according to the present invention, in order to sense the tab through the acceleration sensor or the touch sensor, when the display unit 251 of the mobile terminal 200 is in a deactivated state, It can operate in a specific mode. This particular mode may be referred to as a 'doze mode'.
For example, in the doze mode, in a touch screen structure in which a touch sensor and a display unit 251 have a mutual layer structure, only a light emitting element for outputting a screen in the display unit 251 is turned off, The sensor may be in the on-state state. Alternatively, the dose mode may be a mode in which the display unit 251 is turned off and the acceleration sensor is kept on. Alternatively, the dose mode may be a mode in which the display unit 251 is turned off, and the touch sensor and the acceleration sensor are all kept on.
Therefore, in the doze mode state, that is, when the display unit 251 is turned off, or when the display unit 251 is turned off (the display unit 251 is inactive) When the tap is applied to at least one point on the mobile terminal 200 or a specific point of the main body of the mobile terminal 200, it is possible to detect that the tap is applied from the user through at least one of the on- have.
Hereinafter, embodiments related to a control method that can be implemented in the HMD 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
3 is a flowchart for explaining an operation procedure of a device for controlling image information displayed in the HMD in the HMD related to the present invention.
3, the controller 180 of the HMD 100 according to the embodiment of the present invention displays the initial image information corresponding to the selected content on the display unit 151 (S300). The image information may be generated in the HMD 100 or may be generated in the mobile terminal 200 connected to the HMD 100. If the control information is generated from the mobile terminal 200, the controller 180 controls the mobile terminal 200 to generate the image information through the mobile terminal 200, It is possible to receive image information and output the received image information on the display unit 151 of the HMD 100. [
On the other hand, the generated image information may be related to the virtual space experience or related to the specific multi-image data according to the selected contents. However, in the following description, it is assumed that it is related to the virtual space experience for convenience of explanation.
Meanwhile, when the image information is output as described above, the controller 180 of the HMD 100 can detect the motion of the device set to be the current motion detection target. The image information displayed on the display unit 151 may be controlled according to the motion detection result (S302).
The HMD 100 according to the embodiment of the present invention is displayed on the display unit 151 of the HMD 100 according to an input signal detected from the HMD 100 or the mobile terminal 200 It has been mentioned that image information can be controlled. The input signal sensed by the HMD 100 or the mobile terminal 200 may be a result of sensing the movement of the HMD 100 or the mobile terminal 200.
That is, when the HMD 100 is set as an apparatus to control image information currently displayed in the HMD 100, the HMD 100 controls the movement of the HMD 100, (For example, the acceleration sensor 141 and the gyro sensor 143) included in the controller 140. Then, by displaying the virtual space image in the direction corresponding to the detected motion on the display unit 151, the image information controlled according to the motion detection result of the HMD 100 can be outputted on the display unit 151 have.
Here, if the image information is generated in the HMD 100, the controller 180 of the HMD 100 generates image information on the virtual space image in the specific direction based on the result of detecting the motion of the HMD 100, Can be generated and output. On the other hand, if the image information is generated in the mobile terminal 200, the controller 180 of the HMD 100 can transmit the result of detecting the motion of the HMD 100 to the mobile terminal 200. [ The mobile terminal 200 may control the mobile terminal 200 to generate image information on a virtual space image in a specific direction based on the motion detection result of the HMD 100. The image information generated by the mobile terminal 200 may be received and displayed on the display unit 151.
On the other hand, when the mobile terminal 200 is set as an apparatus to control the image information currently displayed in the HMD 100, the HMD 100 controls the image information to be controlled according to the result of detecting the motion of the mobile terminal 200 On the display unit 151. [0154] FIG. In this case, the HMD 100 may control the control unit 280 of the mobile terminal 200 to detect movement of the mobile terminal 200. The control unit 280 of the mobile terminal 200 may sense the movement of the mobile terminal 200 using at least one of the sensors included in the sensing unit 240 of the mobile terminal 200.
Here, if the image information is generated in the HMD 100, the controller 180 of the HMD 100 may receive the result of detecting the motion from the mobile terminal 200. [ Image information on a virtual space image in a specific direction corresponding to the motion detection result of the mobile terminal 200 can be generated and output. On the other hand, if the image information is generated in the mobile terminal 200, the controller 180 of the HMD 100 generates the image information for the virtual space image in the specific direction corresponding to the motion detection result of the mobile terminal 200 The mobile terminal 200 can control the mobile terminal 200 to generate the mobile terminal 200. The image information generated from the mobile terminal 200 can be received and displayed on the display unit 151.
Meanwhile, in step S302, the controller 180 may detect whether a preset specific situation has occurred in a state of displaying image information according to a result of detecting movement of any one device (S304). The control unit 180 may change a device (hereinafter, referred to as 'controller') for controlling the image information displayed in the HMD 100 when the predetermined condition occurs in step S304 S306).
Here, the preset specific situation may be various.
For example, the preset specific situation may be a gesture of a predetermined user, a touch input, or the like. That is, when the user takes a specific gesture while wearing the HMD 100 or takes a specific gesture while holding the mobile terminal 200, the control unit 180 of the HMD 100 controls the It can be detected that the set specific situation has occurred. The control unit 180 can detect that the preset specific situation has occurred when a preset touch input is detected on the touch screen of the mobile terminal 200. [ The gesture may be sensed through sensors provided in the HMD 100 and sensors provided in the mobile terminal 200. When the gesture or touch input is sensed, The gesture or the touch input of the user can be detected as the input of the user for changing the target device to be detected, that is, the controller.
According to the input of the user, the control unit 180 can change the currently set controller to another controller. Then, the controller 150 senses the motion of the changed controller, and outputs the image information controlled according to the sensed motion on the display unit 151 (S308).
Therefore, if the controller is set as the HMD 100 in step S302, the controller 180 can change the controller to the mobile terminal 200 in step S306. In step S308, the controller 180 detects the motion of the mobile terminal 200 and outputs the image information controlled on the basis of the detected motion on the display unit 151. [ On the other hand, if the controller is set as the mobile terminal 200 in step S302, the controller 180 can change the controller to the HMD 100 in step S306. In step S308, the controller 180 detects the motion of the HMD 100 and outputs the image information, which is controlled according to the detected motion, on the display unit 151. [
In step S304, the controller 180 may detect whether a predetermined situation has occurred. If it is determined in step S304 that no preset condition has occurred, the controller 180 proceeds to step S302 to detect the motion of the currently set controller, and controls the display unit 151 ). ≪ / RTI > On the other hand, if it is determined in step S304 that the predetermined condition has occurred, the controller 180 may change the currently set controller to another controller in step S306. In step S308, the controller 150 senses the motion of the controller and outputs the image information to the display unit 151 according to the detected motion.
In the above description, it is assumed that the predetermined condition is generated according to the user's selection, that is, the user takes a specific gesture while gripping the tofu wearing the HMD 100 or the mobile terminal 200, It is needless to say that a situation that occurs irrespective of the user's selection may be the predetermined condition.
For example, the preset specific situation may be a situation where the amount of power of the currently set controller drops below a predetermined level. In this case, even if the specific gesture or the touch input is not detected, the controller 180 may proceed to step S306 to change the controller to another device.
Alternatively, the control unit 180 may detect that the preset specific situation has occurred according to a function currently being executed in the HMD 100. [ For example, the control unit 180 of the HMD 100 displays image information related to a specific function on the display unit 151 based on the motion of the HMD 100 or the mobile terminal 200 and the direction of the user's gaze , It can be detected that the preset specific situation has occurred.
In the above description, only the controller currently set is changed to another device in the case where the preset specific situation occurs in step S304, but in step S304, it is detected whether the preset specific situation is ended Of course.
For example, when image information related to a specific function is displayed on the display unit 151 as described above, the controller 180 can detect that a preset situation has occurred and change the currently set controller. In this state, if the display of the image information related to the specific function is ended on the display unit 151, the controller 180 can detect that the current situation has ended. In this case, the controller 180 may change the currently set controller again.
Accordingly, in the present invention, when a specific situation occurs, the image information output on the display unit 151 from the time when the occurrence of the specific situation is detected until the occurrence of the specific situation occurs, But can be controlled through a different device. That is, when the currently set controller is the HMD 100, the controller 180 controls the display unit 151 to display the image displayed on the display unit 151 based on the motion sensed through the mobile terminal 200 until the specific situation ends Information can be controlled.
Accordingly, when image information related to a specific function, that is, specific image information, is displayed on the display unit 151 as described above, the control unit 180 controls the display unit 151 to display The display unit 151 can be controlled so that image information controlled according to the detected motion is output on the display unit 151. [
In addition, as described above, when the predetermined condition occurs based on the remaining amount of power of the HMD 100, the controller 180 controls the controller 180 until the amount of power of the HMD 100 reaches a predetermined level, (200). Then, image information controlled according to the motion sensed by the mobile terminal 200 may be output on the display unit 151. When the mobile terminal 200 is set as a controller and the electric power of the HMD 100 is equal to or more than a predetermined level due to the charging of the HMD 100 or the like, the controller 180 may change the controller back to the HMD 100 have.
On the other hand, when the currently set controller is the mobile terminal 200, the control unit 180 controls the display unit 151 to display the image information (e.g., image information) displayed on the display unit 151 based on the motion sensed through the HMD 100 Can be controlled. In this case, the control unit 180 can display the image information controlled according to the motion detected by the HMD 100 on the display unit 151 in a state where the specific image information is displayed on the display unit 151 have. Further, when the remaining power of the mobile terminal 200 is less than a predetermined level, the controller can be changed to the HMD 100.
Meanwhile, in the above description, it is mentioned that the preset specific situation may be a gesture or a touch input of a predetermined user. In this case, the end of the predetermined specific situation may be a case where the specific function executed by the gesture of the predetermined user or the touch input is terminated. That is, for example, when a specific function is executed according to the user's gesture or touch input, while the specific function is being executed, the device controlling the image information displayed on the display unit 151 can be changed to another device And when the specific function is terminated, the image information can be controlled to be controlled according to the motion detected by the original device.
That is, if the currently set controller is the HMD 100, if the specific function corresponding to the gesture or the touch input is the function of browsing the image or the function of browsing the specific information, the controller 180 controls the image browsing function or the information browsing function The image information displayed on the display unit 151 can be controlled according to the motion sensed through the mobile terminal 200. [ When the image browsing function or the information browsing function is terminated, the image information displayed on the display unit 151 can be controlled according to the motion sensed through the HMD 100. [
Meanwhile, the preset specific situation may be the situation where the user's gesture or touch input is detected. Accordingly, when the gesture or touch input of the user is detected, the control unit 180 can change the currently set controller to another device. In this situation, the controller 180 may detect that a gesture of the user or a situation in which the touch input is sensed is terminated when the user's gesture or touch input is detected again.
The control unit 180 controls the display unit 151 according to the motion sensed through the mobile terminal 200. The display unit 151 displays the gesture or the specific function corresponding to the touch input when the currently set controller is the HMD 100. [ It is possible to control the image information displayed on the display device. When the gesture or the specific function corresponding to the touch input is detected again, the control unit may control the image information displayed on the display unit 151 according to the motion sensed through the HMD 100 again.
In the above description, it is assumed that the controller is changed to a controller different from the currently set controller in the case where the predetermined condition occurs. Alternatively, a specific controller corresponding to a specific situation may be set in advance Of course.
For example, the specific gesture sensed from the HMD 100 worn on the user's head may be a device for controlling the image information displayed on the HMD 100, and the HMD 100 may be preset. The specific gesture sensed by the mobile terminal 200 may be a device that controls the image information displayed in the HMD 100 and that the mobile terminal 200 is preset.
Alternatively, when the touch input of the user is sensed through the touch screen of the mobile terminal 200, the control unit 180 may preset the mobile terminal 200 as an apparatus to control the image information displayed in the HMD 100 have. However, when the touch input forms a predetermined pattern, the controller 180 may set a specific device corresponding to the touch input pattern as a device to control image information displayed in the HMD 100 Of course.
Or image information related to a specific function is displayed on the display unit 151 based on the movement of the mobile terminal 200 and the direction of the user's gaze, the HMD 100 or the mobile terminal 200 may be displayed on the display unit 151 according to the type of the displayed image information. The controller 200 may be previously selected as an apparatus for controlling image information displayed in the HMD 100. [ For example, when the displayed image information requires control by a finer user (for example, selection of a specific graphic object or selection of a specific content), if the image information is displayed on the display unit 151, 180 may configure the mobile terminal 200 as an apparatus to control image information displayed in the HMD 100. [
If a specific controller corresponding to a specific situation is set in advance, the controller 180 determines whether a predetermined controller corresponding to the currently generated situation is present in the current HMD 100, It is possible to confirm whether or not the device is set as the device to control the image information displayed on the screen. As a result, it is also possible to change the controller currently set in step S306 to another controller only when the predetermined controller previously set to correspond to the current situation is different from the device set to control the current image information.
Any one of the HMD 100 and the mobile terminal 200 may be preset as a basic controller for controlling image information displayed on the display unit 151. [ In this case, the controller 180 can detect the motion of any one of the devices set in the basic controller and output the image information according to the detection result on the display unit 151 without the user's selection or the occurrence of the specific situation have. Here, the basic controller may be set by a user and may be changed at any time according to a user's selection.
Meanwhile, when the controller 180 of the HMD 100 outputs image information to be controlled according to the motion detected by any one of the HMD 100 and the mobile terminal 200 in step S302, The device may not detect motion. For example, when the image information is controlled according to the motion of the HMD 100 in step S302, the controller 180 of the HMD 100 may turn off the motion detection function of the mobile terminal 200 It is possible. In this case, the control unit 281 of the mobile terminal 200 may turn off an acceleration sensor or a gyroscope sensor for detecting the movement of the mobile terminal 200.
On the other hand, when the image information is controlled according to the motion of the mobile terminal 200, the controller 180 of the HMD 100 may turn off the motion detection function of the HMD 100 in step S302. In this case, the HMD 100 may turn off the acceleration sensor, the gyro sensor, or the like for detecting the motion of the HMD 100.
4 is a flowchart illustrating an operation of changing the device controlling the HMD 100 according to the amount of power of the HMD 100 and the mobile terminal 200 connected to the HMD 100 in the HMD 100 related to the present invention Fig.
4, when the controller 180 of the HMD 100 according to the embodiment of the present invention detects that a preset specific situation has occurred according to the detection result of step S304 of FIG. 3, (S400). Here, the 'target device' may be a device that controls the image information currently displayed in the HMD 100, that is, a device other than the device set in the controller, or a device corresponding to the detected specific situation.
In step S402, the control unit 180 may check whether the amount of power of the target device to be detected is greater than a predetermined level as a result of the power amount check in step S400. If it is determined in step S402 that the checked amount of power is equal to or greater than the predetermined level, the control unit 180 may change the currently set controller to the 'target device' (S404). 3, the control unit 180 may detect the motion of the 'target device' and output the image information controlled according to the detected motion on the display unit 151. In this case,
On the other hand, if it is determined in step S402 that the checked power of the 'target device' is less than a preset level, the controller 180 may not change the currently set controller. In this case, the control unit 180 may display notification information on the display unit 151 to inform that the 'target device' is insufficient.
Meanwhile, in FIG. 4, it is described that, in the case where a preset specific situation occurs, whether or not the currently set controller is changed according to the amount of power of the 'target device' is explained. Alternatively, the controller may be changed Of course it is possible. In this case, the control unit 180 may display notification information on the display unit 151 to notify the user that the battery power is insufficient and the controller is changed accordingly.
In addition, even if the remaining power of the battery is insufficient, the image information displayed on the display unit 151 may be controlled according to the motion sensed by the device currently set to the controller according to the user's selection to be. Or if the HMD 100 and the mobile terminal 200 are both in an insufficient amount of power, the control unit 180 determines whether the amount of power consumed by the HMD 100 or the user of the mobile terminal 200 It is needless to say that the image information displayed on the HMD 100 can be controlled based on the motion detected by any one of the devices according to the selection.
According to the above description, the controller 180 of the HMD 100 according to the embodiment of the present invention may change the currently set controller based on the specific image information displayed on the display unit 151 There is a bar. FIG. 5 is a flowchart illustrating an operation of changing an apparatus for controlling image information displayed in the HMD according to a graphic object displayed on a display unit in the HMD related to the present invention. In the following description, it is assumed that the HMD 100 is set as a controller for convenience of explanation. In this case, the controller 180 detects motion of the HMD 100, for example, a rotational motion state or a linear motion state, and outputs a virtual space image of a specific direction corresponding to the sensed result on the display unit 151 .
5, the control unit 180 of the HMD 100 according to the embodiment of the present invention may output image information controlled according to the motion detection result of the HMD 100 (S500). Accordingly, the control unit 180 can output the virtual space image in the direction of the movement of the HMD 100 on the display unit 151. [
In this state, the controller 180 can sense the direction in which the user's gaze is directed. For example, the control unit 180 tracks the position of the user's pupil using the sensed value of the eye tracking sensor 142, and recognizes one area on the display unit 151 that the user is looking at according to the tracked pupil position can do. For example, if the user views the one area on the display unit 151 for more than a preset time, the control unit 180 can determine that the user is looking at the one area.
In this case, the control unit 180 may detect whether a specific graphic object is displayed in an area on the display unit 151 that the user is looking at (S504). If it is detected in step S504 that the user is gazing at the area where the specific graphic object is displayed, the information related to the predetermined specific graphic object may be displayed on the display unit 151 in step S506.
Here, if the information related to the predetermined graphic object is displayed, the controller 180 may determine that the preset status of step S304 has occurred. Accordingly, the currently set controller can be changed from the HMD 100 to the mobile terminal 200.
Accordingly, the control unit 180 may cause the display unit 151 to output image information to be controlled according to a result of the motion of the mobile terminal 200 (S506). For example, if the image information is generated and output by the HMD 100, the controller 180 receives a result of detecting movement of the mobile terminal 200 from the mobile terminal 200 in step S506 And generates image information according to the received motion detection result and outputs the generated image information. However, if the image information is generated in the mobile terminal 200, the controller 180 controls the mobile terminal 200 to generate image information according to the result of detecting the motion of the mobile terminal 200 in step S506, ), And can receive the generated image information from the mobile terminal 200 and output it.
In this state, the controller 180 can check whether the display of the information related to the specific graphic object is finished (S510). For example, when the user gazes at a display area other than the area where the image information is displayed, or when a touch command or a touch gesture of a predetermined user applied to the touch screen of the mobile terminal 200 If so, the display of the information related to the specific graphic object can be terminated. When the display of the information related to the specific graphic object is terminated, the controller 180 may change the currently set controller from the mobile terminal 200 to the HMD 100 again. In this case, image information according to the movement of the head of the user, which is sensed through the HMD 100, may be output on the display unit 151.
In the above description, it is assumed that the currently set controller is changed by a touch gesture according to a user's selection, a touch input is detected, or specific information is displayed or a remaining amount of power is insufficient. However, But is not limited thereto.
For example, the predetermined state may be a state in which a specific event occurs in the mobile terminal 200. In this case, the controller 280 of the mobile terminal 200 may transmit information related to the event occurring in the mobile terminal 200 to the HMD 100. In this case, the controller 180 of the HMD 100 may display notification information for notifying the event generated in the mobile terminal 200 on the display unit 151 of the HMD 100. In this case, the notification information may include information related to the generated event, and the state in which the notification information is displayed may be a predetermined state in which the controller is changed.
Accordingly, the controller 180 controls the image information displayed on the display unit 151 so that the mobile terminal 200 can be set. The control unit 180 of the HMD 100 may receive information on a specific event according to the selection of the user from the mobile terminal 200. Here, the selection of the user may be applied through the touch screen of the mobile terminal 200.
The control unit 180 of the HMD 100 may display the information received from the mobile terminal 200 on the display unit 151. [ Accordingly, information on an event that has occurred in the mobile terminal 200 can be displayed on the display unit 151 of the HMD 100. In this case, the user's touch input sensed through the touch screen of the mobile terminal 200 may include image information displayed on the display unit 151 of the HMD 100 (event related information received from the mobile terminal 200 In the corresponding area of the display screen.
In the above description, in the HMD 100 according to the embodiment of the present invention, a controller for controlling the image information displayed in the HMD 100 according to the user's selection or a predetermined specific situation is provided to the HMD 100, (200) is described in detail with reference to a plurality of flowcharts.
In the following description, an example in which a controller for controlling image information displayed in the HMD 100 is changed in the HMD 100 according to the embodiment of the present invention, Let's take a closer look with reference to the drawings.
6 is an exemplary diagram illustrating an example in which the HMD is controlled according to the motion of the HMD or the controller device in the HMD related to the present invention.
Referring to FIG. 6, the first diagram of FIG. 6 shows an example in which a controller for controlling image information displayed in the HMD 100 is set as the HMD 100. In this case, roll, yaw, and pitch are sensed according to the movement of the head of the wearer wearing the HMD 100, as shown in the first drawing of FIG. 6, The image information displayed on the display unit 151 of the HMD 100 can be controlled according to the roll, yaw, and pitch values.
For example, the vertical line of sight of the image 600 in the virtual space displayed on the display unit 151 of the HMD 100 may be changed according to the change of the pitch value. That is, as the pitch value increases, the viewing angle of the user looking at the image 600 of the virtual space may be higher, and accordingly, as the user views the ceiling portion of the virtual space image 600, The image information can be changed so that the portion becomes larger.
In addition, the viewing angle of the image 600 in the virtual space displayed on the display unit 151 of the HMD 100 may be changed according to the change of the yaw rate. That is, as the yaw rate increases, the viewing angle of the user looking at the image 600 of the virtual space may be shifted to the left or right side. Accordingly, when the user views the left or right side of the virtual space image 600 The image information can be changed so that the left side wall or the right side wall is made larger, as if looking at the wall portion.
Meanwhile, in this state, when a preset situation occurs, a controller for controlling image information displayed in the HMD 100 may be changed to the mobile terminal 200. [ In this case, the control unit 180 of the HMD 100 may change the image information displayed on the display unit 151 based on the movement of the mobile terminal 200. 6, when the user rotates the mobile terminal 200 forward or backward in the longitudinal direction 650, the user rotates the mobile terminal 200 on the display portion 151 of the HMD 100 The vertical line of sight of the image 600 of the displayed virtual space can be changed. That is, as the user tilts the mobile terminal 200 forward or backward, the gaze angle of the user looking at the image 600 in the virtual space may become higher or lower, The image information may be changed so that the ceiling or the floor is made larger.
When the user rotates the mobile terminal 200 left or right in the lateral direction 660, the left and right viewing angles of the image 600 in the virtual space displayed on the display unit 151 of the HMD 100 are changed . That is, as the angle at which the user rotates the mobile terminal to the left or right is greater, the viewing angle of the user looking at the image 600 of the virtual space may be shifted to the left or right side, The image information can be changed so that the left wall or the right wall is made larger as if looking at the left wall or the right wall portion of the screen 600. [
7A and 7B are diagrams illustrating an example in which user input for changing the device controlling the HMD 100 is detected in the HMD 100 related to the present invention.
7A shows an example in which a user inputs an input for changing a controller for controlling image information displayed in the HMD 100 through the mobile terminal 200. [ For example, as shown in FIG. 7A, the user inputs a predetermined touch input to the touch screen of the mobile terminal 200, or receives a predetermined gesture while holding the mobile terminal 200 There may be cases when you take.
7A shows a state in which a user views contents via the HMD 100 and a touch of the mobile terminal 200 connected to the HMD 100 wirelessly or by wire is shown in FIG. And shows an example in which a user applies a preset touch input on the screen 251.
For example, when the user is watching the content through the HMD 100, the mobile terminal 200 may be in the dose mode state described above. 7A, only the light emitting element for outputting a screen on the touch screen 251 is turned off, and the touch sensor 251 or the acceleration sensor 252 is turned off, The gyroscope sensor or the like may be in a state of maintaining the on state. Accordingly, there is no image information to be displayed, but it may be in a state capable of sensing an applied touch input or detecting the movement of the mobile terminal 200 or the like.
7A, when the touch input is applied, the control unit 280 of the mobile terminal 200 can sense the touch input and notify the control unit 180 of the HMD 100 of the touch input . The controller 180 of the HMD 100 may sense the touch input as a user input for changing a controller for controlling currently displayed image information. Accordingly, the control unit 180 may set a device other than the currently set controller as a device that controls image information displayed in the HMD 100. [ The controller 180 of the HMD 100 may detect the input of the user to set the controller to the mobile terminal 200 when the touch input as shown in FIG. .
On the other hand, FIG. 7 (a) may be a plurality of touch inputs forming a predetermined touch pattern. The touch pattern may be set to correspond to a specific device. Accordingly, when a plurality of touch inputs sensed through the touch screen 251 form a predetermined pattern, the controller 180 of the HMD 100 controls the corresponding device to display image information displayed on the HMD 100 It is also possible to set the device to be controlled.
Meanwhile, when the mobile terminal 200 is in the doze mode, the controller 280 of the mobile terminal 200 can sense the movement of the mobile terminal 200. [ Accordingly, as shown in FIGS. 7 (b) and 7 (c), when the user rotates the mobile terminal 200 or the mobile terminal 200 swings up and down in a state of holding the mobile terminal 200, It is possible to detect a position shift caused by a gesture or the like. The control unit 180 of the mobile terminal 200 may notify the controller 180 of the HMD 100 of the sensed gesture.
Then, the control unit 180 of the HMD 100 may sense the user's gesture as an input of the user for changing the controller for controlling the currently displayed image information. Accordingly, the control unit 180 may set a device other than the currently set controller as a device that controls image information displayed in the HMD 100. [
Meanwhile, FIG. 7B shows an example of detecting the head gesture of the user from the HMD 100, rather than the mobile terminal 200. FIG. For example, the gesture of such a user may be a gesture such as that shown in (a), (b), or (c) of Fig. 7b, in which the user shakes his head left or right or back and forth, . If the user's gesture is detected more than a preset number of times or a preset time, the controller 180 can detect that the user's gesture is to change the currently set controller.
Therefore, if the gesture similar to the one shown in FIG. 7B is repeated more than a preset time or a preset number of times, the controller 180 outputs the currently set controller and the other device to the HMD As an apparatus for controlling image information displayed on the display unit 100. [ Alternatively, the controller 180 of the HMD 100 may detect the gesture as an input of the user for setting the controller to the HMD 100.
7 (b), the controller 180 of the HMD 100 controls the movement of the HMD 100 in a direction in which the front surface of the HMD 100 faces the specific surface (e.g., the front surface or the rear surface) of the mobile terminal 200 State, it can be detected that the currently set controller is to be changed. For example, the control unit 180 of the HMD 100 detects that the specific surface of the mobile terminal 200 faces the HMD 100 within a predetermined distance using a camera provided in the HMD 100 . The control unit 180 of the mobile terminal 200 may determine whether the mobile terminal 200 is connected to a specific surface of the HMD 100 from a camera provided on the front surface (the surface on which the display unit 251 is formed) It is possible to detect that the specific surface of the display device faces the display device within a predetermined distance. And informs the control unit 180 of the HMD 100 of this. For example, the detection may be performed through an infrared sensor, a laser sensor, an optical sensor (or a photosensor) provided in the HMD 100 or the mobile terminal 200, and the like.
Meanwhile, when a controller for controlling image information displayed on the display unit 151 of the HMD 100 is set, the controller 180 of the HMD 100 can display information related to the device currently set as the controller have. 8A and 8B show examples of screens displayed differently according to devices controlling image information displayed in the HMD in the HMD related to the present invention.
Referring to FIG. 8A, FIG. 8A shows an example of a screen displayed when the controller is set as the HMD 100. FIG. Here, the case where the controller is set as the HMD 100 means that the image information displayed on the display unit 151 of the HMD 100 is controlled according to the movement of the head of the wearer wearing the HMD 100 .
In this case, the control unit 180 may display the graphic object 800 including information on the controller currently set in at least a part of the display unit 151. [ 8A shows an example in which the controller is set in the HMD 100 in this case.
Meanwhile, the HMD 100 may be set as a basic controller by a user. In this case, when the image information displayed on the display unit 151 is controlled by the motion sensed by the HMD 100 (when the HMD 100 is set to the controller), the control unit 180 displays 151 may not display an indication to inform the user. Thus, as shown in FIG. 8A (b), image information without special display can be displayed on the display unit 151.
On the other hand, when the currently set controller is the mobile terminal 200, the control unit 180 may display information for informing the controller on the display unit 151. [ 8B, the control unit 180 may display the graphic object 850 on the display unit 151 to indicate that the currently set controller is the mobile terminal 200. In this case, When the controller is changed to the mobile terminal 200, the controller 180 controls the operation of the HMD 100 according to the motion detected by the motion detected by the mobile terminal 200, Information on the display unit 151 can be displayed.
8A, if the controller is changed to the mobile terminal 200 while the HMD 100 is set as the primary controller, the controller 180 determines whether the currently set controller is the primary controller, It is possible to display on the display unit 151 that the device is not set as the device. In this case, the control unit 180 determines whether the image information displayed on the display unit 151 is in a state in which the controller (e.g., the HMD 100) Are set to the controller).
8B, when the controller is set to the HMD 100 and the controller is changed to the mobile terminal 200 according to a specific situation or a user's selection, a graphic object 852 in the form of a border formed on the boundary of an area where image information is displayed on the display unit 151 as shown in FIG. In this case, the graphic object 852 in the form of a border may be for indicating to the user that the device currently set as the controller is not the device set as the basic controller.
The controller 180 of the HMD 100 according to the embodiment of the present invention not only selects the user but also displays information related to a specific graphic object on the display unit 151, It is mentioned that the device to control the image information displayed in the HMD 100 can be changed. Fig. 9 shows an example of such a case. In the following description, it is assumed that the HMD 100 is set as a controller for controlling image information to be displayed for convenience of explanation.
9, the control unit 180 of the HMD 100 according to the embodiment of the present invention detects movement of the head of the user by sensors provided in the HMD 100, that is, an acceleration sensor 141 and / or the gyro sensor 143. [0033] The image information displayed on the display unit 151 can be controlled according to the sensed head movement.
In addition, the control unit 180 may track the position of the user's eyes through the eye tracking sensor 142 and recognize a specific area on the display unit 151 to be examined by the user. Accordingly, as shown in the first diagram of FIG. 9, when the user gazes at the area where the TV 900 is displayed among the virtual objects in the virtual space displayed on the display unit 151, the user can recognize this. For example, when the user views the area on the display unit 151 on which the TV 900 is displayed for more than a preset time, the controller 180 can recognize that the TV 900 is staring the TV 900.
In this case, the controller 180 may determine that the TV 900 of the virtual objects is selected by the user. Then, the control unit 180 may display on the display unit 151 information related to the virtual object selected by the user, i.e., the TV 900 and the function. Accordingly, as shown in the second diagram of FIG. 9, the control unit 180 controls the functions associated with the TV 900, that is, different graphic objects 920, 922, and 924 can be displayed on the display unit 151.
If the information (920, 922, 924) related to a specific graphic object (TV 900) is displayed on the display unit 151 as described above, the controller 180 determines whether the currently set controller It can be judged that it has occurred. This is because, as shown in the second drawing of FIG. 9, since a plurality of pieces of information are displayed, more detailed control for selecting one of them may be required for the user.
Accordingly, the control unit 180 can change the device currently set as the controller to another device. Accordingly, if the currently set controller is the HMD 100 device as in the above-described assumption, the controller 180 can change the controller to the mobile terminal 200. If the controller is changed as described above, the controller 180 may display information on the display unit 151 to inform the controller of the change. For example, the control unit 180 may display a graphical object 930 on the display unit 151, including information about the currently set controller and the controller to be changed, as shown in the third diagram of FIG.
9, when the controller is changed to the mobile terminal 200, the controller 180 displays the display on the display unit 151 according to the motion detected by the mobile terminal 200, Can be controlled. Accordingly, the controller 180 displays any one of the graphic objects 922 corresponding to the motion of the mobile terminal 200, separately from the other graphic objects 920 and 924 displayed on the display unit 151 . That is, as shown in the fourth diagram of FIG. 9, the controller 180 may further include a graphic object 950 in the form of a border around one of the graphic objects 922 corresponding to the motion of the mobile terminal 200 And may indicate that any one of the graphic objects 922 is selected by the user.
According to the above description, the controller 180 of the HMD 100 according to the embodiment of the present invention can determine whether the controller is changed according to the amount of power remaining in each device. 10A and 10B are diagrams illustrating an example in which an apparatus for controlling image information displayed in the HMD 100 is changed in the HMD 100 according to the present invention in accordance with the power state of the apparatus.
10A, when the currently set controller is changed from the HMD 100 to the mobile terminal 200, notification information 1000 for informing the controller is displayed on the display unit 151 FIG. In this case, the control unit 180 may check the amount of power remaining in the device to be set as the controller, that is, the mobile terminal 200.
If the amount of power remaining in the mobile terminal 200 is less than a predetermined level as a result of the check, the controller 180 may display information 1010 for informing the user. If the amount of power of the device to be set as the controller is insufficient, the controller 180 may not change the currently set controller.
Meanwhile, as described above, not only when the controller changes, but also when the user views the content, the controller can be changed according to the amount of power. That is, the control unit 180 can measure the amount of power remaining in the HMD 100 while the user is viewing the content. If the measured amount of power is less than a predetermined level, the control unit 180 displays notification information 1050 indicating that the current amount of power of the HMD 100 is insufficient, as shown in the first drawing of FIG. 10B, 151).
The control unit 180 can change the device currently set as the controller. That is, as shown in the first drawing of FIG. 10B, if the device currently set as the controller is the HMD 100, the controller 180 can change the controller to the mobile terminal 200. When the controller is changed as described above, the controller 180 may display the information 1060 on the display unit 151 to inform the user of the change as shown in the second drawing of FIG. 10B.
10A and 10B, even if a specific situation occurs according to the remaining amount of power of the device, even if the device currently set as the controller remains in the controller or if the specific situation does not occur, For example. However, it is needless to say that the device set by the controller may be determined according to the user's selection. That is, even if the amount of power of the specific device is insufficient, the specific device may be set as a controller or may be maintained as a controller.
In the above description, the image information displayed on the display unit 151 is controlled only in accordance with the motion of the HMD 100 or the mobile terminal 200. However, The motion of the HMD 100 and the mobile terminal 200 may be detected according to the function or the user's selection. In this case, the device for generating image information of the HMD 100 or the mobile terminal 200 receives the motion detection result from the HMD 100 and the mobile terminal 200, It is needless to say that image information may be generated. In this case, the functions controlled according to the respective movements of the HMD 100 and the mobile terminal 200 on the image information or the content may be interlocked with each other, and the HMD 100, And image information according to the motion of the mobile terminal 200 may be displayed on the display unit 151.
