[Details of the embodiment of the present invention]
Specific examples of a program, a system, and a method for controlling a head mounted display according to an embodiment of the present invention will be described below with reference to the drawings. In addition, this invention is not limited to these illustrations, is shown by the claim, and intends that all the changes within the meaning and range equivalent to the claim are included. In the following description, the same reference numerals are given to the same elements in the description of the drawings, and redundant descriptions are omitted.

  FIG. 1 shows an HMD system 100 including a head mounted display (hereinafter referred to as “HMD”) 110 according to the present embodiment. The HMD system 100 includes an HMD 110 that is worn on the user's head, a control circuit unit 120, a sensor 130, and an external controller 140. The HMD 110 includes a display 112 that is a non-transmissive display device and a sensor unit 114. The control circuit unit 120 displays a right-eye image and a left-eye image on the display 112, thereby providing a three-dimensional image using parallax between both eyes as a virtual space. By arranging the display 112 in front of the user's eyes, the user can be immersed in the virtual space. The virtual space includes various objects that can be operated by the background and the user, as will be described later.

  The display 112 may include a right-eye sub-display that provides a right-eye image and a left-eye sub-display that provides a left-eye image. Moreover, as long as the image for right eyes and the image for left eyes can be provided, you may be comprised by one display apparatus. For example, the right-eye image and the left-eye image can be provided independently by switching the shutter so that the display image can be recognized by only one eye at high speed.

  The control circuit unit 120 is a computer connected to the HMD 110, provides a virtual space to the display 112, and functions to operate various objects displayed in the virtual space. The control circuit unit 120 stores a program for controlling such an operation. The control circuit unit 120 may not be mounted on the HMD 110 and may be configured as another hardware (for example, a known personal computer or a server computer via a network). In addition, the control circuit unit 120 may implement only a part of functions in the HMD 110 and implement the remaining functions in different hardware.

  The sensor 130 detects information related to the position and movement of the HMD 110. The sensor 130 includes a sensor unit 114 and a detection unit 132. The sensor unit 114 may include a plurality of light sources. The light source is, for example, an LED that emits infrared rays. The detection unit 132 is, for example, an infrared sensor, and detects information about an angle in the real space of the HMD 110 according to the user's movement by detecting infrared rays from the light source as detection points of the HMD 110 over time. Then, it is possible to determine the time change of the angle of the HMD 110 based on the change with time of the information detected by the detection unit 132, and to detect information regarding the position and movement of the HMD 110.

  Information regarding the angle acquired by the sensor 130 will be described with reference to FIG. XYZ coordinates are defined around the head of the user wearing the HMD 110. The vertical direction in which the user stands upright is the Y axis, the front-rear direction orthogonal to the Y axis and connecting the center of the display 112 and the user is the Z axis, and the horizontal direction orthogonal to the Y axis and the Z axis is the X axis. Then, the inclination angle θx (so-called pitch angle), θy (so-called yaw angle), and θz (so-called roll angle) of the HMD 110 around each axis are detected, and information on the position and movement of the HMD 110 is detected by their change over time. can do.

  The sensor 130 may be configured by only one of the sensor unit 114 fixed near the display 112 and the detection unit 132. The sensor unit 114 may be a geomagnetic sensor, an acceleration sensor, or an angular velocity (gyro) sensor, and the inclination of the HMD 110 (particularly, the display 112) mounted on the user's head is detected using at least one of them. To do. Thereby, the information regarding the position and movement of the HMD 110 can be detected. For example, the angular velocity sensor can detect the angular velocities around the three axes of the HMD 110 over time according to the movement of the HMD 110, and determine the temporal change in the angle (tilt) around each axis. In this case, the detection unit 132 is not necessary. The detection unit 132 may include an optical camera. In this case, information regarding the position and movement of the HMD 110 can be detected based on the image information, and the sensor unit 114 is unnecessary.

The function of detecting information related to the position and movement of the HMD using the sensor 130 is referred to as position tracking. The relationship between the position tracking by the sensor 130 and the virtual camera 1 arranged in the virtual space 2 will be described with reference to FIGS. 3A and 3B. In order to describe the positional relationship between the virtual camera 1 and the sensor 130, the position of the sensor 130 is the position of the detection unit 132 when the detection unit 132 is provided, and the sensor unit 114 when the detection unit 132 is not provided. The position of 3A is a three-dimensional schematic diagram showing the relationship between the sensor 130 in the real space and the virtual space 2, and FIG. 3B is a plan view of the relationship between the sensor 130 in the real space and the virtual space 2 as seen from the Y direction. . The virtual camera 1 is disposed inside the virtual space 2, and the sensor 130 is virtually disposed outside the virtual space 2 (real space).

The virtual space 2 is formed into a celestial sphere having a plurality of meshes 3 that are substantially square or substantially rectangular. Each mesh is associated with spatial information of the virtual space 2, and a visual field image to be described later is formed based on this spatial information. In the present embodiment, as shown in FIG. 3B, it is preferable to adjust so that the center point 21 of the celestial sphere is always arranged on the line connecting the virtual camera 1 and the sensor 130 in the XZ plane. For example, when the user wearing the HMD moves and the position of the virtual camera 1 moves in the X direction, the area of the virtual space 2 so that the center 21 is located on the line segment between the virtual camera 1 and the sensor 130. Is changed.

  The external controller 140 is a device capable of communication so that various commands can be sent to the control circuit unit 120, and is preferably configured by a portable terminal capable of wireless communication. The external controller 140 can be any portable device that includes a CPU, a main memory, an auxiliary memory, a transmission / reception unit, a display unit, and an input unit that are bus-connected to each other. For example, a smartphone, a PDA, a tablet computer, a game console, and a notebook PC can be applied, and a portable terminal including a touch panel is preferable. The user can influence the object displayed in the virtual space by performing various touch operations including tap, swipe, and hold on the touch panel of the external controller 140.

  The HMD system 100 may include headphones including a microphone as any element. Thereby, the user can give a voice instruction to a predetermined object (game object or the like described later) in the virtual space. Further, in order to receive a broadcast of a television program on a virtual television in a virtual space, the HMD system 100 may include a television receiver in any element.

  FIG. 4 is a diagram illustrating functions of the control circuit unit 120 for realizing display processing of the virtual space 2 in the HMD system 100 and operation of objects displayed in the virtual space 2. The control circuit unit 120 controls an output image to the display 112 mainly based on inputs from the sensor 130 and the external controller 140.

The control circuit unit 120 includes a display control unit 200, an object control unit 300, and a determination unit 400. The display control unit 200 includes a motion detection unit 210, a visual field determination unit 220, a visual field image generation unit 230, and a spatial information storage unit 240. The object control unit 300 includes an object information storage unit 310 and a virtual camera information storage unit 320. The sensor 130, the display control unit 200, the object control unit 300, and the display 112 are connected to be communicable with each other, and can be connected via a wired or wireless communication interface. The external controller 140 is communicably connected to the object control unit 300. The spatial information storage unit 240, the object information storage unit 310, and the virtual camera information storage unit 320 include various tables for providing output information corresponding to inputs from the sensor 130 and the external controller 140 to the display 112. The determination unit 400 determines whether or not an input from the sensor 130 or the external controller 140 satisfies a predetermined condition and various objects are operated so as to satisfy the predetermined condition.

  Based on the angle information detected over time by the sensor unit 114 and the angle information of the HMD 110 detected over time by the detection unit 132, the sensor 130 displays information regarding the position and movement of the HMD 110, and the display control unit 200 and Output to the object control unit 300. The motion detection unit 210 detects the motion of the HMD 110 based on input information from the sensor 130. Then, the visual field direction serving as a reference line of sight that defines the direction of the HMD 110 in the virtual space 2 is detected. Then, the detected information is output to the visibility determining unit 220.

  The visual field determination unit 220 relates to the visual field region of the virtual camera 1 in the virtual space 2 based on the virtual space information stored in the spatial information storage unit 240 and input information from the sensor 130 (information from the motion detection unit 210). Determine information. The view image generation unit 230 generates a part of the 360 degree panorama constituting the virtual space as a view image based on the view information. The view field image is output to the display 112. The field-of-view image includes two two-dimensional images for the left eye and right eye, and these are superimposed on the display 112, thereby providing the user with a virtual space 2 as a three-dimensional image.

  The object control unit 300 identifies an operation target object based on object information in the virtual space stored in the object information storage unit 310 and user commands from the sensor 130 and the external controller 140. Then, the virtual camera information stored in the virtual camera information storage unit 320 is adjusted based on a predetermined user operation command to the operation target object. The adjusted virtual camera information is output to the display control unit 200, and the view field image is adjusted. In addition, an operation corresponding to a predetermined user operation command is performed on the operation target object, and object control information is output to the display 112 and the display control unit 200. Specific processing of the object operation will be described later.

  Note that hardware elements for realizing each function of the control circuit unit 120 can be constituted by a CPU, a memory, and other integrated circuits. Each function is realized by various programs as software elements loaded in the memory. Accordingly, those skilled in the art will understand that these functional blocks can be realized by hardware, software, or a combination thereof.

  With reference to FIGS. 5A to 5C, the visual field region 6 along the celestial sphere of the virtual space 2 that is determined by the visual field determination unit 220 will be described. 5A is a three-dimensional schematic diagram showing the visual field region 6, FIG. 5B is a YZ plane view of the visual field region 6 viewed from the X direction, and FIG. 5C is an XZ plane view of the visual field region 6 viewed from the Y direction. It is. As shown in FIG. 5A, the visual field region 6 constitutes a part of the virtual space 2. The visual field area 6 is determined based on the visual field direction 5, and the visual field direction 5 is determined based on the position and direction of the virtual camera 1. The visual field region 6 is a first region 61 that is a predetermined range around the X axis at the intersection between the virtual space 2 and the visual field direction 5, and a predetermined range around the Y axis at the intersection between the virtual space 2 and the visual field direction 5. 2 viewing areas 62. The first region 61 is set as a range including the polar angle α with the visual field direction 5 as the center. The second region 62 is set as a range including the azimuth angle β with the visual field direction 5 as the center. That is, the view field region 6 can be a region on a spherical surface having the polar angle θ in the XY plan view and the azimuth angle β in the XZ plan view with respect to the view direction 5 from the position of the virtual camera 1.

  With reference to FIGS. 6 and 7, the processing operation of the control circuit unit 120 related to the object operation in the virtual space 2 will be described. FIG. 6 is a block diagram illustrating functions of the object control unit 300 shown in FIG. The object control unit 300 includes an object specifying unit 330 for specifying an operation target object, and an object operation unit 340 for operating the specified operation target object.

  The object specifying unit 330 includes a reference line-of-sight calculation unit 331, an object determination unit 332, and an operation target object selection unit 333. The object specifying unit 330 specifies an object arranged on the visual field direction 5 that is the reference line of sight shown in FIGS. 5A to 5C in the virtual space 2 by the tilting operation of the HMD 110. For this purpose, the reference line-of-sight calculation unit 331 sets the field-of-view direction 5, and the object determination unit 340 determines whether an object is placed in the field-of-view direction 5. Further, when an object is arranged in the visual field direction 5, the operation target object selection unit 360 selects the object as the operation target object.

  The object operation unit 340 includes an external controller operation determination unit 341, a tilt operation determination unit 342, a virtual camera adjustment unit 343, an object operation specification unit 344, an object operation execution unit 345, and an object operation table 346. The object operation unit 340 performs an operation according to the tilt operation of the HMD 110 on the operation target object specified by the object specifying unit 300.

The external controller operation determination unit 341 determines whether a user's touch operation is input to the external controller 140. The tilt motion determination unit 342 determines whether a tilt motion (particularly the tilt direction) is input to the HMD 110. The virtual camera adjustment unit 343 adjusts the position and direction of the virtual camera 1 during the object operation. The object operation specifying unit 344 specifies an operation for the operation target object according to the object operation table 346. The object operation execution unit 345 performs an object operation and generates a resulting image as a view image.

  FIG. 7 shows an example of the object operation table 346. The object operation table 346 associates the user action with the action of the operation target object. That is, one-to-one correspondence is made so that the operation target object takes a predetermined action with respect to an operation such as a tilt change operation on the HMD 110 by the user or an input to the external controller 140. The action of the operation target object may be associated by an input operation to the HMD 110 or the external controller 140 alone, or may be associated with a coordinated operation of the HMD 110 and the external controller 140. Details of each action for the input will be described later.

Note that when the object operation table 346 includes information on the user action and the operation target object, the object operation unit 340 may have a function as the object specifying unit 330. That is, the operation target object information included in the object operation table 346 may be specified by the object specifying unit 330 or may be set in advance.

  Next, with reference to FIGS. 7 to 11, a processing flow for object operation in the virtual space 2 according to the present embodiment will be described. The object operation process can be realized by the interaction of the external controller 140, the sensor 130, the HMD 100, and the control circuit unit 120.

First, the position of the HMD 110 is detected by the sensor 130 (step S130-1).
The detection information of the sensor 130 is transmitted to the control circuit unit 120, and the visual field determination unit 220 determines the visual field direction 5 that is the reference visual line by the motion detection unit 210 (step S120-1). The visual field direction 5 is determined in association with a predetermined position of the visual field image as described above. The predetermined position is preferably the center point of the view image, but is not limited thereto, and may be any settable position of the view image. Further, the visual field direction may be displayed in a superimposed manner on the visual field image as some mark (for example, a circular or palm icon). Subsequently, the field of view information in the virtual space 2 is determined by the field of view determination unit 220 based on the position information and / or the tilt information of the HMD 110. Further, the visual field image generation unit 230 generates a visual field image to be displayed on the display 112 of the HMD 110 based on the visual field information (step S120-2).

  Next, the view field image is displayed on the HMD 110 (step S110-2). As will be described later, a plurality of objects that can be operated are displayed in the view field image. When the user wearing the HMD 110 moves the head while the view image is displayed on the HMD 110, at least one of the plurality of objects arranged in the virtual space 2 is the view image. Alignment is performed so as to correspond to a predetermined position.

  An example of a view field image displayed on the HMD 110 is shown in FIG. The view image G1 is a state in the virtual space displayed on the HMD 110. In the actual HMD 110, a right-eye image and a left-eye image are prepared, but for the sake of simplicity, only the left-eye image will be described here.

  In the present embodiment, a plurality of characters Ck imitating a “bear” are displayed and rubbed in the illustrated virtual space. In the illustrated field of view, the character Ck appears from outside the screen (lower left of G1), rushes up the slope Slp along the arrow DD1, changes direction when reaching the plane Pln, and proceeds along the arrow DD2. It disappears outside the screen. Note that “in the illustrated field of view” is described because the field of view can be changed by the inclination of the HMD 110 or the operation of the external controller (steps S130-1, S110-1, FIG. 7). S120-1 to S120-3, S110-2).

  Next, information on operation input (step S140-1) by the external controller 140, information on position detection of the HMD 110 by the sensor 130 (step S130-2), information on tilt by the HMD 110 (step S110-3), and the control circuit unit 120 (step S120-4). Based on these pieces of information, the control circuit unit 120 controls the position and tilt of the virtual camera (step S120-5).

  In the present embodiment, as shown in FIG. 9, the user's operation on the external controller (smart phone) 140 is reflected in the position of the virtual camera VCam. That is, as shown in the drawing, when the finger is moved forward on the touch panel of the smartphone, the virtual camera VCam moves forward (ie, advances) in the virtual space, and accordingly, the visual field region is also V1 to V2. To change.

  Next, the relationship between the virtual camera VCam and the character Ck in the virtual space will be described. As illustrated in FIG. 10, the virtual camera VCam includes a visual field region V1 that is a region displayed on the HMD 110 and a detection region Det that is a region included in the visual field region V1. The detection area is set within a distance L from the virtual camera VCam.

  Two types of characters Ck1 and Ck2 are displayed in the virtual space. The character Ck1 is included in the visual field area V1 of the virtual camera VCam, but is not included in the detection area Det. The character Ck1 proceeds along the traveling direction (X direction) in the order of the positions P_1, P_2, and P_3, and has a line of sight in the traveling direction (see dotted arrows). On the other hand, the character Ck2 is included in the field of view area V1 of the virtual camera VCam, and is also included in the detection area Det at some positions (P_12, P_13, etc.). In the present embodiment, the character included in the detection area Det is controlled so as to advance while directing its line of sight toward the virtual camera VCam. That is, when the character Ck is at the position P_11 outside the detection area Det, the line of sight is the traveling method (X direction). When the character Ck2 moves and proceeds to the position P_12 in the detection area Det, the appearance changes so that the line of sight that has been directed in the direction of travel up to that point becomes the direction of the virtual camera VCam (as seen by the virtual camera VCam). . At P_13, which is slightly advanced, the appearance is further changed, and the line-of-sight direction is further changed so that the line of sight does not deviate from VCam. And if it becomes position P_14 which is outside detection field Det, a line of sight will be returned to a direction of travel again. In this way, by performing a control in which only a character located close to him / her moves while keeping his / her eyes aligned with each other, the character can have a more natural movement.

  Even if there is a character Ck in the detection area Det, when trying to match the line of sight with the virtual camera VCam, if the direction of the neck is obviously wrong, natural expression cannot be made. Therefore, when the character Ck faces the virtual camera VCam, when the angle formed by the traveling direction and the line of sight becomes a certain value or more, the above-described processing may not be performed and the neck may not be bent any more.

  FIG. 11 shows an example of the case where the virtual camera VCam is moved by a user operation when the character Ck3 moving along the traveling direction X is looking toward the virtual camera VCam. Specifically, at the position P_31 outside the detection area Det_0 in the virtual camera VCam located at the position CP_0 before the movement, the character Ck3 has a line of sight in the traveling direction. The character Ck3 advances in the X direction, and at the position P_32 in the detection area Det_0, the character Ck3 looks toward the virtual camera VCam located at CP_0. At this time, when the user performs a swipe operation (slide operation) from the left to the right on the smartphone 140, the virtual camera VCam moves from CP_0 to CP_1, and accordingly, the detection area also changes from Det_0 to Det_1. . At this time, the character Ck3 moved from P_32 to P_33 changes its appearance so that its line of sight is directed to the virtual camera VCam after the movement.

  In this way, as long as the virtual camera moves as long as it is within the detection area, the character's line of sight will continue to follow the virtual camera VCam, providing a new game experience. Natural movement can be expressed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment.
