Therefore, there is a need for technology that can immerse in fashion shows without being restricted by the capacity of the venue.

In addition, for a user who is watching a fashion show using a terminal, it may not be possible to grasp the degree of interest in the fashion show. For example, when the user purchases clothes worn by a model from a terminal, it is estimated that there is a degree of interest in the clothes. On the other hand, if the user does not purchase the clothes, the user may purchase after the fashion show, and not having the degree of interest may not always be the low interest level. Therefore, there is a need for a technique for grasping the degree of interest of the user watching a fashion show.

The present disclosure has been made in view of the background as described above, and an object in one aspect is to provide a technology for grasping the degree of interest of a user watching a fashion show.

According to an embodiment, a computer implemented method is provided for providing information via a head mounted device. The method comprises the steps of: defining a virtual space; disposing a model object fitted with one or more clothing objects in the virtual space; displaying the model object on the head mount device; Detecting an action on the one or more clothes objects by the user of the device, and based on the actions, the degree of interest of the user on the one or more clothes objects displayed on the head mount device or the model object And determining.

In the example illustrated in FIG. 2, the computer 200 is configured to be provided outside the HMD 110. However, in another aspect, the computer 200 may be incorporated in the HMD 110. As one example, a portable information communication terminal (for example, a smartphone) including the monitor 112 may function as the computer 200.

In addition, the computer 200 may be configured to be commonly used for the plurality of HMDs 110. According to such a configuration, for example, since the same virtual space 2 can be provided to a plurality of users, each user can enjoy the same application as other users in the same virtual space 2.

In one embodiment, in the HMD system 100, a global coordinate system is preset. The global coordinate system is parallel to the vertical direction in real space, the horizontal direction perpendicular to the vertical direction, and the front-back direction perpendicular to both the vertical direction and the horizontal direction.
Have one reference direction (axis). In the present embodiment, the global coordinate system is one of viewpoint coordinate systems. Therefore, the horizontal direction, the vertical direction (vertical direction), and the front-rear direction in the global coordinate system are defined as an x-axis, a y-axis, and a z-axis, respectively. More specifically, in the global coordinate system, the x-axis is parallel to the horizontal direction of the real space. The y-axis is parallel to the vertical direction of the real space. The z axis is parallel to the front and back direction of the real space.

In one aspect, the HMD sensor 120 includes an infrared sensor. Infrared sensor is H
When the infrared rays emitted from the light sources of the MD 110 are respectively detected, the presence of the HMD 110 is detected. The HMD sensor 120 further detects the position and the inclination of the HMD 110 in the real space according to the movement of the user 190 wearing the HMD 110 based on the value of each point (each coordinate value in the global coordinate system). More specifically, the HMD sensor 120
Each value detected over time can be used to detect temporal changes in the position and inclination of the HMD 110.

The global coordinate system is parallel to the real space coordinate system. Therefore, HMD sensor 120
The respective inclinations of the HMD 110 detected by are equivalent to the inclinations around the three axes of the HMD 110 in the global coordinate system. HMD sensor 120 is an HMD in a global coordinate system
Based on the inclination of 110, the uvw visual field coordinate system is set to the HMD 110. The uvw visual field coordinate system set in the HMD 110 corresponds to the visual point coordinate system when the user 190 wearing the HMD 110 views an object in the virtual space 2.

[Uvw view coordinate system]
The uvw view coordinate system will be described with reference to FIG. FIG. 3 is a diagram conceptually illustrating the uvw visual field coordinate system set in the HMD 110 according to an embodiment. HMD sensor 12
0 detects the position and tilt of the HMD 110 in the global coordinate system when the HMD 110 is activated. The processor 10 HMDs the uvw view coordinate system based on the detected values.
Set to 110.

As shown in FIG. 3, the HMD 110 sets a three-dimensional uvw visual field coordinate system centered on the head of the user 190 wearing the HMD 110 (origin). More specifically, HMD1
10 is to tilt the horizontal direction, vertical direction, and longitudinal direction (x-axis, y-axis, z-axis) defining the global coordinate system around each axis by an inclination around each axis of the HMD 110 in the global coordinate system The three directions newly obtained by
The pitch direction (u axis), the yaw direction (v axis), and the roll direction (w axis) of the visual field coordinate system are set.

In one aspect, when the user 190 wearing the HMD 110 stands upright and views the front, the processor 10 may use the HMD for the uvw view coordinate system parallel to the global coordinate system.
Set to 110. In this case, the horizontal direction (x axis) and
The y axis) and the longitudinal direction (z axis) coincide with the pitch direction (u axis), the yaw direction (v axis), and the roll direction (w axis) of the uvw visual field coordinate system in the HMD 110.

After the uvw visual field coordinate system is set to the HMD 110, the HMD sensor 120
Based on the movement of 0, the inclination (the amount of change of the inclination) of the HMD 110 in the set uvw visual field coordinate system can be detected. In this case, the HMD sensor 120 sets the inclination of the HMD 110 to
The pitch angle (θu), the yaw angle (θv), and the roll angle (θw) of the HMD 110 in the uvw visual field coordinate system are respectively detected. The pitch angle (θu) represents the inclination angle of the HMD 110 around the pitch direction in the uvw view coordinate system. The yaw angle (θv) represents the inclination angle of the HMD 110 around the yaw direction in the uvw view coordinate system. The roll angle (θw) represents the inclination angle of the HMD 110 around the roll direction in the uvw view coordinate system.

The HMD sensor 120 detects the HMD 110 based on the detected inclination angle of the HMD 110.
Sets the uvw visual field coordinate system in the HMD 110 after movement of the HMD 110. HM
The relationship between D110 and the uvw view coordinate system of the HMD 110 is always constant regardless of the position and tilt of the HMD 110. When the position and the inclination of the HMD 110 change, the position and the inclination of the uvw view coordinate system of the HMD 110 in the global coordinate system change in conjunction with the change of the position and the inclination.

In one aspect, the HMD sensor 120 detects the HMD 110 based on the light intensity of the infrared light acquired based on the output from the infrared sensor and the relative positional relationship between the plurality of points (for example, the distance between each point). The position in the real space of may be specified as a relative position to the HMD sensor 120. Also, the processor 10 may determine the origin of the uvw visual field coordinate system of the HMD 110 in the real space (global coordinate system) based on the identified relative position.

[Virtual space]
The virtual space 2 will be further described with reference to FIG. FIG. 4 is a diagram conceptually illustrating an aspect of representing virtual space 2 according to an embodiment. Virtual space 2 is the center 21 360
It has a totally celestial spherical structure covering the whole of the direction of power. In FIG. 4, the celestial sphere in the upper half of the virtual space 2 is illustrated so as not to complicate the description. In the virtual space 2, each mesh is defined. The position of each mesh is previously defined as coordinate values in the XYZ coordinate system defined in the virtual space 2. The computer 200 associates virtual images that can be viewed by the user 190 with the partial images that constitute content (still images, moving images, etc.) that can be developed in the virtual space 2 associated with the corresponding meshes in the virtual space 2. 22 provides the user 190 with the virtual space 2 to be deployed.

In one aspect, in the virtual space 2, an XYZ coordinate system having a center 21 as an origin is defined. The XYZ coordinate system is, for example, parallel to the global coordinate system. Since the XYZ coordinate system is a kind of viewpoint coordinate system, the horizontal direction, the vertical direction (vertical direction), and the front-rear direction in the XYZ coordinate system are defined as an X axis, a Y axis, and a Z axis, respectively. Therefore, X in the XYZ coordinate system
The axis (horizontal direction) is parallel to the x axis of the global coordinate system, the Y axis (vertical direction) of the XYZ coordinate system is parallel to the y axis of the global coordinate system, and the Z axis (longitudinal direction) of the XYZ coordinate system is It is parallel to the z-axis of the global coordinate system.

When the HMD 110 starts up, that is, in the initial state of the HMD 110, the virtual camera 1
It is arranged at the center 21 of the virtual space 2. The virtual camera 1 similarly moves in the virtual space 2 in conjunction with the movement of the HMD 110 in the real space. Thus, HMD 1 in real space
Changes in the position and orientation of 10 are similarly reproduced in the virtual space 2.

As in the case of the HMD 110, a uvw visual field coordinate system is defined in the virtual camera 1. The uvw view coordinate system of the virtual camera in the virtual space 2 is defined to interlock with the uvw view coordinate system of the HMD 110 in the real space (global coordinate system). Therefore, H
When the inclination of the MD 110 changes, the inclination of the virtual camera 1 also changes accordingly. Also,
The virtual camera 1 can also move in the virtual space 2 in conjunction with the movement of the user 190 wearing the HMD 110 in the real space.

Since the orientation of the virtual camera 1 is determined according to the position and the inclination of the virtual camera 1, the user 1
The line of sight (reference line of sight 5), which is a reference when the image 90 is viewed by the virtual space image 22, is the virtual camera 1
It depends on the direction of The processor 10 of the computer 200 defines a view area 23 in the virtual space 2 based on the reference line of sight 5. The visibility region 23 is H in the virtual space 2.
It corresponds to the field of view of the user 190 wearing the MD 110.

The gaze direction of the user 190 detected by the gaze sensor 140 is a direction in the viewpoint coordinate system when the user 190 visually recognizes an object. The uvw view coordinate system of the HMD 110 is equal to the view coordinate system when the user 190 views the monitor 112. Also, u of virtual camera 1
The vw vision coordinate system is linked to the uvw vision coordinate system of the HMD 110. Therefore, the HMD system 100 in accordance with an aspect may be configured such that the user 190 detected by the gaze sensor 140
Can be regarded as the viewing direction of the user 190 in the uvw view coordinate system of the virtual camera 1.

[User's gaze]
The determination of the gaze direction of the user 190 will be described with reference to FIG. FIG. 5 is a top view of the head of a user 190 wearing the HMD 110 according to one embodiment.

In one aspect, the gaze sensor 140 detects the gaze of each of the right eye and the left eye of the user 190. In one aspect, if the user 190 is looking close, the gaze sensor 140
The eyes R1 and L1 are detected. In another aspect, when the user 190 is looking far, the gaze sensor 140 detects the sight lines R2 and L2. In this case, the angle between the lines of sight R2 and L2 with respect to the roll direction w is smaller than the angle between the lines of sight R1 and L1 with respect to the direction of roll w. The gaze sensor 140 transmits the detection result to the computer 200.

When the computer 200 receives the detection values of the lines of sight R1 and L1 from the gaze sensor 140 as the detection result of the line of sight, the gaze point N1 which is the intersection of the lines of sight R1 and L1 is specified based on the detection values. On the other hand, when the computer 200 receives the detection values of the sight lines R2 and L2 from the gaze sensor 140, the computer 200 specifies the intersection of the sight lines R2 and L2 as the gaze point. The computer 200 identifies the gaze direction N0 of the user 190 based on the identified position of the fixation point N1. The computer 200 detects, for example, the direction in which the straight line passing through the midpoint of the straight line connecting the right eye R and the left eye L of the user 190 and the gaze point N1 is the line of sight direction N0. The gaze direction N0 is the direction in which the user 190 is actually pointing the gaze with both eyes. Further, the line-of-sight direction N0 corresponds to the direction in which the user 190 actually points the line of sight with respect to the view area 23.

When the user 190 moves the HMD 110 worn on the head, the virtual camera 1 also moves in conjunction with the movement. As a result, the position of the view area 23 in the virtual space 2 changes. By this,
The view image displayed on the monitor 112 is updated to an image of the virtual space image 22 superimposed on the view area 23 in the direction to which the user 190 is directed in the virtual space 2. The user 190 is

[Control structure of HMD system]
The control structure of the HMD system 100 will be described with reference to FIG. FIG. 10 is a sequence chart showing a part of the process performed in the HMD system 100 according to an embodiment.

As shown in FIG. 10, in step S1010, the processor 10 of the computer 200 specifies virtual space image data as the virtual space definition module 231, and defines the virtual space 2.

In step S1020, the processor 10 initializes the virtual camera 1. For example,
The processor 10 arranges the virtual camera 1 at a predetermined center point in the virtual space 2 in the work area of the memory, and directs the line of sight of the virtual camera 1 in the direction in which the user 190 is facing.

In step S1030, the processor 10 operates as the view image generation module 223,

In step S1032, the monitor 112 of the HMD 110 displays a view image based on the view image data received from the computer 200. The user 190 wearing the HMD 110 can recognize the virtual space 2 when viewing the view image.

In step S1034, the HMD sensor 120 detects the position and inclination of the HMD 110 based on the plurality of infrared light beams emitted from the HMD 110. The detection result is output to the computer 200 as motion detection data.

[Face tracking]
Hereinafter, with reference to FIGS. 11 to 13, a specific example for detecting a user's facial expression (movement of a face) will be described. In FIGS. 11 to 13, a specific example of detecting the movement of the mouth of the user 190 will be described as an example. Note that the detection method described in FIGS.
Other organs that constitute the face of the user 190 (eg, eyes, eyebrows, nose,
It can be applied to detection of movement of the cheek).

FIG. 11 is a diagram for describing control for detecting a mouth from the face image 50 of the user. First
The face image 50 generated by the camera 116 includes the nose and the mouth of the user 190.

The face organ detection module 261 specifies the mouth area 51 from the face image 50 by pattern matching using the mouth template 245 stored in the face information 244. In one aspect, the face organ detection module 261 sets a rectangular comparison area in the face image 50, and changes the size, position, and angle of the comparison area, and the image of the comparison area and the mouth template 245. Calculate the degree of similarity with the image. The face organ detection module 261 specifies, as the mouth area 51, the comparison area for which the degree of similarity larger than the predetermined threshold is calculated.

The face organ detection module 261 further determines the comparison area based on the relative relationship between the position of the comparison area whose calculated similarity is greater than the threshold and the position of the other face organs (for example, the eyes and the nose). Whether or not to correspond to the mouth area is determined.

The tracking module 262 detects the mouth area 51 detected by the face organ detection module 261.
To detect more detailed mouth shape.

FIG. 12 is a diagram (part 1) for explaining the process in which the tracking module 262 detects the shape of the mouth. Referring to FIG. 12, tracking module 262 sets a plurality of contour detection lines 52 for detecting the shape of the mouth (a lip contour) included in mouth region 51. The plurality of contour detection lines 52 are set at predetermined intervals in a direction orthogonal to the height direction of the face.

The tracking module 262 may detect a change in luminance value of the mouth area 51 along each of the plurality of contour detection lines 52, and identify a position at which the change in luminance value is abrupt as a contour point. More specifically, the tracking module 262 specifies a pixel whose luminance difference (that is, luminance value change) with an adjacent pixel is equal to or greater than a predetermined threshold as an outline point. The luminance value of the pixel is obtained, for example, by integrating the RBG value of the pixel with a predetermined weighting.

The tracking module 262 identifies two types of contour points from the image corresponding to the mouth area 51. The tracking module 262 determines contour points 53 corresponding to the contours on the outside of the mouth (lip).
And a contour point 54 corresponding to the inner contour of the mouth (lip). In one aspect, when three or more contour points are detected on one contour detection line 52, the tracking module 262 may identify the contour points at both ends as the outer contour point 53. In this case, tracking module 262 may identify contour points other than outer contour point 53 as inner contour points 54. The tracking module 262 can also identify the detected contour point as the outer contour point 53 when two or less contour points are detected on one contour detection line 52.

FIG. 13 is a diagram (part 2) for explaining the process in which the tracking module 262 detects the shape of the mouth. In FIG. 13, the outer contour point 53 is shown as a white circle, and the inner contour point 54 is shown as a hatched circle.

The tracking module 262 interpolates between the plurality of inner contour points 54 to
The mouth shape 55 is identified. In this case, the contour point 54 can be said to be a mouth feature point. In one aspect, the tracking module 262 identifies the mouth shape 55 using a non-linear interpolation method such as spline interpolation. In other aspects, tracking module 262 may
The mouth shape 55 may be specified by complementing between a plurality of outer contour points 53. In yet another aspect, the tracking module 262 excludes the outline points that greatly deviate from the assumed mouth shape (a predetermined shape that can be formed by the upper lip and the lower lip of the person), and the mouth shape according to the remaining contour points. 55 may be specified. Thus, the tracking module 26
2 specifies the movement (shape) of the user's mouth. Note that the method of detecting the mouth shape 55 is not limited to the above, and the tracking module 262 may detect the mouth shape 55 by another method.
Also, tracking module 262 may similarly detect user eye and eyelid activity. The tracking module 262 may be configured to be able to detect the shape of organs such as the cheek and nose.

The structure of face tracking data will be described with reference to FIG. Figure 14
It is a figure showing an example of the data stored in storage 12 for face tracking. The face tracking data represents position coordinates in the uvw view coordinate system of a plurality of feature points constituting the shape of each organ. For example, points m 1, m 2,... Shown in FIG. 14 correspond to the inner contour points 54 constituting the mouth shape 55. In one aspect, the face tracking data is coordinate values in the uvw view coordinate system with the position of the first camera 116 as a reference (origin). In another aspect, face tracking data is coordinate values in a coordinate system based on a feature point defined in advance for each organ (origin). As an example, points m1, m2,... Are coordinate values in a coordinate system with the origin being any one of the inner contour points 54 that corresponds to the mouth angle.

The computer 200 transmits the generated face tracking data to the server 150. Server 150 transfers this data to another computer 200 in communication with computer 200. The other computer 200 receives the received face tracking data,
The face tracking data is reflected on an avatar object corresponding to the user 190 of the computer 200 that has provided the face tracking data. Other users communicating with the user 190 can visually recognize the avatar object on which the expression is reflected.

The change in emotion of the user 190 will be described with reference to FIGS. 15 and 16. Figure 15.
Represents a feature point of the face acquired when the user 190 has no expression. FIG. 16 shows facial feature points obtained when the user 190 is surprised. The feature point P shown in FIG. 15 and FIG.
It represents feature points of the face of the user 190 acquired by the tracking module 262.

In one aspect, the processor 10 captures the face of the user 190 with the first camera 116 and the second camera 117. The processor 10 generates face tracking data based on the acquired image. The face tracking generated at this time functions as reference data 248. The processor 10 stores the generated reference data 248 in the memory module 240.

The feature point P shown in FIG. 15 corresponds to the reference data 248. On the other hand, the feature point P shown in FIG. 16 corresponds to face tracking data acquired as needed while the user 190 is immersed in the virtual space 2.

In the example shown in FIG. 16, since the user 190 is surprised, the eye feature point P spreads in the height direction of the face and the eyelid feature point P moves upward in comparison with FIG. in this way,
The variation amount of the face tracking data with respect to the reference data represents the degree of interest of the user 190 for the content developed in the virtual space 2.

Thus, the processor 10 may classify the degree of interest of the user 190 into a predetermined degree (high, medium, low) when the variation of the face tracking data relative to the reference data exceeds the predetermined variation. .

In one aspect, the processor 10 calculates the variation amount of the face tracking data with respect to the reference data for each feature point, and makes the above determination based on the sum. In another aspect, the processor 10 calculates the variation amount only for a predetermined feature point (for example, a feature point corresponding to a corner of the mouth) having a large degree of change due to emotion, and makes the above determination based on the sum.

According to the above, the processor 10 can generate an image by automatic photographing when the user 190 shows an interest in the content (for example, a fashion of an avatar, etc.).

[Technical thought]
First, the technical idea according to the present disclosure will be described. According to the present embodiment, the fashion show is reproduced in the virtual reality space (for example, the virtual space 2). When the user 190 wearing the HMD 110 looks at the clothes worn by the model in the virtual space 2 for a predetermined time, it can see detailed information of the clothes. In existing fashion shows in real space, for example, clothes purchased on a smartphone can be regarded as popular clothes. On the other hand, according to the present embodiment, since the fashion show is developed in the virtual space 2, clothes that share the virtual space 2 and where the line of sight of the user watching the same fashion gathers up to the detailed information Even if it can not be seen, it can be judged as a popular garment. For example,
Garment in which the line of sight from each user continues to be visible for a certain period of time, clothing that has been viewed to detailed information, clothing purchased by the user, and a preference for clothing based on the above-mentioned technology for grasping the user's facial expression wearing the HMD 110 Clothing having a high height may be identified as a popular clothing.

Also, according to virtual reality, it is possible to make recommendations specific to each user.
The same model can be reappeared in a fashion show at another timing by putting on clothes in a different coordinate with clothes that the gaze to the model has stopped for a certain period of time but has not resulted in purchasing, and the same model can be reappeared in a fashion show. You can also

In addition, when personal preference information of each user is accumulated to a certain extent, it is possible to create a fashion show suitable for the person. Or, a model that appears in a fashion show,
It can also be your own 3D model. In this case, the user 190 tries on clothes with a high degree of interest in the virtual space 2, and the user 190 confirms in advance how it looks when purchased by visually recognizing the 3D model in such a state. be able to.

[Determining degree of interest]
A method for the server 150 to derive the degree of interest in clothes by the user 190 will be described with reference to FIG. FIG. 17 is a flowchart showing a part of the process executed by the server.

In step S1710, the processor 151 of the server 150 defines the virtual space 2.

In step S1720, the processor 151 generates a fashion show image in which the model has worn clothes.

In step S1730, the processor 151 projects a fashion show image on the virtual space 2. When the projected image is displayed by the monitor 112 of the HMD 110, the user 190 can view the fashion show. While the user 190 is looking at the monitor 112 of the HMD 110, the line of sight may be detected by the gaze sensor 140.

In step S1740, processor 151 detects that the line of sight of the user of HMD 110 is directed to the clothes, based on the signal output from the sensor.

At step S1750, processor 151 determines, based on the signal sent from the sensor,
It is determined whether the line of sight on the clothing continues for a predetermined time or more. The processor 151 is
If it is determined that the line of sight continues for a predetermined time or more (YES in step S1750), the control is switched to step S1770. If not (NO in step S1750
Processor 151 switches control to step 1760).

In step S1760, processor 151 presents detailed information on clothes. User 1
The fact that the 90 lines of sight continue for a certain period of time or longer may be presumed that the user 190 is interested in the clothes. Then, detailed information of the clothes is presented to the user 190.
In addition, the trigger in which detailed information is shown is not restricted to the time when the gaze is continuing. For example,
The detailed information may be presented based on the operation of the user 190 or based on another user recommending the clothing.

In step S1770, the processor 151 determines whether to change the clothes worn by the model. For example, the processor determines whether to change the clothes based on whether the clothes have been purchased. In this case, the clothes that were purchased but not purchased can be changed.

In step S1780, the processor 151 derives the degree of interest based on the line of sight (operation information). As an example, the degree of interest is classified according to the time when the gaze continued. More specifically, for example, if the time is less than one second, the degree of interest of the user is determined to be low. If the time is more than 1 second and less than 5 seconds, the degree of interest is determined to be medium. If the time is 5 seconds or more, the degree of interest is determined to be high. In addition, the time which a gaze wants to continue is not restricted to said example,
Other time intervals may be used.

In step S1790, the processor 151 outputs the degree of interest.
The sights of the fashion show developed in the virtual space 2 will be described with reference to FIGS. FIG. 18 is a diagram illustrating an example of an image displayed on the monitor 112 of the HMD 110. It is a figure showing an example of the picture displayed on monitor 112 of HMD110. This image is displayed based on the data sent from the server 150.

The monitor 112 includes a model object 1810 representing each of a plurality of models, an audience object 1820 representing an audience, a stage 1830, and a model object 1840.
And display. The model object 1810 may be either an existing model object or a virtual model object. The model object 1810 stands behind the stage 1830, wears a predetermined clothes, walks the stage 1830 in a predetermined order, and travels between the audience objects 1820 and 1820. The model object 1840 wears a clothing object 1841. When the model object 1840 reaches the tip of the stage 1830, it returns to the rear of the stage 1830 again and replaces the next model object.

FIG. 19 is a diagram showing a state in which the monitor 112 shows the detailed information 1900 in the virtual space 2. While the model object 1840 is at the center of the stage 1830
If the time during which the 90 lines of sight are directed to the model object 1840 is longer than a predetermined time, the monitor 112 displays detailed information 1900 as a pop-up object.
To present.

The detailed information 1900 includes the detailed description of the clothes worn by the model object 1840 and the recommendation by other users. Furthermore, the detailed information 1900 is a menu object that receives an input of an instruction by the user 190 wearing the HMD 110 ("purchase")
, "Return", "Show more"). The user 190 can give any instruction to the computer 200 by directing the line of sight to any of the menu objects or by operating the controller 160. Computer 200
When the user receives the "purchase" instruction, an input screen of information for ordering the clothes worn by the model object 1840 is presented. In another aspect, an accessory associated with the garment (eg, bag, shoes, hat, skirt, coat, etc.) or other garment or accessory associated with the model object 1840 may be recommended.

FIG. 20 is a diagram showing a screen for accepting the purchase of the clothes worn by the model object 1840. When the user 190 selects the menu object "Purchase" on the screen shown in FIG. 19, the monitor 112 displays the screen of FIG. More specifically, monitor 112 further displays object 2000. The object 2000 accepts input of a user ID and password for accessing a fashion show account. The user 1 D identifies a user 190 who desires to purchase clothing worn by the model object 1840. The password protects the user ID. The user 190 is
When the user ID and password defined in advance are input and the confirmation is pressed, the object 2000 is switched to an object representing an input screen of information necessary to purchase clothes.

[Configuration Summary]
(1) In one aspect, the processor 151 defines the virtual space 2 and places the model object 1840 equipped with one or more clothes objects 1841 in the virtual space 2. The HMD 110 displays the model object 1840 on the HMD 110. The processor 151 detects an action on the one or more clothes objects 1841 by the user 190 of the HMD 110, and the interest degree of the user 190 for the one or more clothes objects 1841 or model objects 1840 displayed on the HMD 110 based on the actions. To determine

(2) In another aspect, the processor 151 detects the line of sight of the user 190 of the HMD 110, and the line of sight of the user 190 of the HMD 110 is poured on the object (for example, the entire model object 1840 or the clothing object 1841) Based on the degree of interest of the user 190. The degree of interest indicates the degree of interest in the object to which the gaze is directed. The degree of interest may be, for example, the length of time for which the user gazes at the object, or information on whether the user watching the fashion show gazes at the object for a predetermined period of time or longer. It is defined as the number of times seen. For example, an object in which the user's gaze is directed for a certain period of time may be estimated to be of interest by the user, and a predefined value may be counted as the degree of interest.
On the other hand, it is assumed that the object that the user turned his or her gaze but immediately turned off looks at a low degree of interest by the user, and the degree of interest is zero. In another aspect, for example, an object that has been frequently gazed at the object is estimated to be highly interesting to the user.

(3) In another aspect, the processor 151 detects movement of a body other than the head of the user 190 of the HMD 110. The HMD 110 generates H based on the signal from the server 150.
A body object (a hand object, a foot object, etc.) corresponding to a body (for example, a hand, a foot, etc.) other than the head of the user 190 of the MD 110 and operates in the virtual space 2 in conjunction with the detection result of the motion of the body Display body objects. The processor 151 detects an operation of specifying one or more clothing objects 1841 by the body object, and determines the interest degree of the user 190 based on the detection result of the operation of specifying the one or more clothing objects 1841 by the body object. Do.

(4) In another aspect, the processor 151 detects the expression of the user 190 of the HMD 110, and based on the detection result of the expression of the user 190 of the HMD 110, one or more clothing objects 1841 or model objects displayed on the HMD 110 A degree of interest of the user 190 for 1840 is determined. For example, the user 190 is a clothing object 1841
Alternatively, in the case where the model object 1840 is surprised to enlarge the eye or the mouth is widely opened, the processor 151 estimates that the user 190 has a high degree of interest, and sets a predetermined value as the degree of interest. Alternatively, the processor 151 classifies the degree of interest for the user 190 as “high”. In such cases, the processor 151 may further consider whether the user 190 has uttered speech to determine the degree of interest. Since the accuracy of the degree of interest estimated in this case is higher than the degree of interest estimated based only on the change in expression, more detailed analysis is possible. Further, the processor 151 may analyze the utterance content of the user 190, and may determine that there is an interest in the clothing object 1841 or the model object 1840 if a specific word such as a positive expression or an exclamation word is included in the utterance content. Because certain words are also taken into account, the degree of interest may be more accurate.

(5) In another aspect, the processor 151 detects the sound emitted by the user 190 of the HMD 110, and one or more clothing objects 1841 or model objects displayed on the HMD 110 based on the sound being emitted. A degree of interest of the user 190 for 1840 is determined. For example, the processor 151 may determine the degree of interest of the user 190 based on whether the voice is emitted by the user 190. Alternatively, the processor 151 analyzes the content of the speech uttered by the user 190 and uses positive words (for example, "clean", "cute", "nice", etc.) or exclamation expressions ("o!"). If the user 190 includes a specific word predefined as a term representing a preference for fashion as described above, the user 190 determines that the interest for the clothing object 1841 or the model object 1840 displayed at the timing when the voice is emitted is high. And classifies the degree of interest to the clothing object 1841 or the model object 1840 as “high”. As another example, processor 151 may analyze speech content and determine emotion based on the intonation obtained from the analysis result. In this case, when it is determined that the emotion is a positive emotion, it is determined that the user 190 is interested in the clothing object 1841 or the model object 1840 displayed on the HMD 110 at that timing. As yet another example, when the processor 151 analyzes the content of the voice based on the speech of the user 190 and determines that the content of the voice designates the clothing object 1841 or the model object 1840 (for example, “that hat, cute Etc.), it is determined that the user 190 is highly interested in the clothing object 1841 or the model object 1840.

(6) In another aspect, the processor 151 includes one or more clothing objects 184
Information related to one or more clothing objects 1841 (for example, materials of the clothing, bags and other accessories matching the clothing, evaluations of other users, etc.) based on the fact that the operation for 1 continues for a predetermined time ) Is presented to virtual space 2.

(7) In another aspect, the processor 151 presents to the HMD 110 an interface object (for example, the object 2000) that accepts the purchase of the object in which the user 190 is looking.

(8) In another aspect, the processor 151 presents again an object that has not been purchased after the gaze of the user 190 has been poured, in a manner different from the manner in which the object has been presented. For example, a clothing object 1841 worn on one model object but not purchased may be worn on another model object and presented again to the virtual space 2 fashion show. The impression of clothing can vary depending on the model you are wearing, so
In this way, the degree of interest of the clothing object 1841 can be increased.

(9) In another aspect, the processor 151 places in the virtual space 2 the model object 1840 on which each of the plurality of clothing objects 1841 is attached, and stores the degree of interest of the user 190 for each clothing object 1841 in the storage 154 .

(10) In another aspect, the processor 151 can generate a plurality of model objects 184
0 is sequentially arranged in the virtual space 2, and the degree of interest of the user 190 for each model object is stored in the storage 154, respectively.

(11) In another aspect, the processor 151 changes the display mode of the clothing object 1841 displayed on the HMD 110 based on the degree of interest by another user. For example, a model to wear the clothing object 1841 is changed. Alternatively, in a scene in which the clothing object 1841 appears, a lighting pattern different from the lighting pattern (color, brightness, presence or absence of blinking, etc.) used in a scene in which another clothing object appears may be used.
In this way, the appearance of the clothing object changes, so the degree of interest to the user can be increased.

(12) In another aspect, the processor 151 determines information on clothes to be presented to the user 190 among the plurality of clothes based on the determination result of the degree of interest of the user 190, and an interface including information on the determined clothes. Present the object in virtual space 2 Virtual camera 1
When the data of the video according to is sent to the HMD 110, the monitor 112 displays the information of the determined clothing (material and other attribute information, information on recommended bags and other accessories related to the clothing, comments of other users, etc.) So that the user 190 can check their information,
Other accessories can also be purchased as appropriate.

(13) In another aspect, the processor 151 stores a plurality of panoramic videos including the appearance of the model wearing the clothes in the memory (for example, the storage 154) of the computer, defines the virtual space 2, and The panoramic video is displayed on the HMD 110 by reading out the panoramic video and expanding the panoramic video in the virtual space 2. Further, the processor 151 detects the motion of the user 190 of the HMD 110, and determines the interest degree of the user 190 for the clothes or model included in the panoramic video displayed on the HMD 110 based on the detection result of the motion. Based on the determination result of the degree of interest, an interface object (for example, object 2000) for accepting the purchase of clothes is presented in the virtual space 2.

(14) In another aspect, the processor 151 controls the progress of the panoramic video displayed on the HMD 110 based on the determination result of the degree of interest of the user 190.

[data structure]
The data structure of the server 150 will be described with reference to FIGS. 21 and 22. Figure 21.

Indicates the presence or absence of an order by the user for the clothing identified in

Referring to FIG. 22, storage 154 further includes tables 2210, 2220 and 2230.

The table 2210 includes history ID 2211, user ID 2212, and target ID 2.
213 and act 2214. The history ID 2211 identifies each of the records that make up the table 2210. The user ID 2212 identifies a user who has viewed a fashion show developed in the virtual space 2. The target ID identifies an object to which the user's gaze is directed. For example, as the target ID, a clothing ID or an ID of each accessory is used.
An operation 2214 represents an operation performed by the user. Operation 2214 is, for example, an HMD
The table 2220 may include other operations such as a gaze time of the user wearing the 110, an operation by the controller 160 of the user, an expression or voice of the user, etc. The table 2220 includes a transaction ID 2221, a user ID 2222, and an operation 2223 ,

The interest level 2233 represents the level of interest level for the combination of the model specified by the model ID 2231 and the clothing specified by the clothing ID 2232. The degree of interest 2233 is shown in three levels (high, medium, low) as an example, but may be further divided. Alternatively, the size of the degree of interest 2233 is, for example, 0.
It may be digitized as 100. As quantification, for example, the longest watched time may be set to 100, and the time of the gaze by another user to that time may be shown as a percentage.

Control structure
The holding of a fashion show in the virtual space 2 and the ordering of clothes will be described with reference to FIG. FIG. 23 shows the user 190 and the computer 20 connected to the HMD 110.
0 is a flowchart showing a part of processing executed by the server 150. In addition, data (for example, an application program for expanding a fashion show in a virtual space, content data, etc.) and functions (an arithmetic function, a communication function, etc.) of the server 150
When the HMD 110 includes the HMD 110, the process may be performed by the processor of the HMD 110.

In step S2310, the user 190 mounts the HMD 110.
In step S2315, the processor 10 activates the VR fashion show application based on the instruction of the user 190.

In step S2320, processor 151 accepts login by the user 190 to the VR fashion show based on the signal sent from computer 200. V
The video of the R fashion show may be either live video or video recording. For example, when the VR fashion show is held in an on-demand format using video recording data, the server 150 transmits, to the HMD 110, data for developing the VR fashion show based on the initial coordinated version.

In step S2325, processor 151 detects the line of sight to the clothes worn by the model based on the signal sent from computer 200. For example, when the user 190 gazes at a model object 1840 displayed in the virtual space 2, a signal from a gaze sensor is sent to the server 150 via the computer 200. When the server 150 receives a signal from the gaze sensor, it starts measurement and continues measurement until no signal is received. In addition, the detection method of the user's interest level with respect to the clothes which a model wears is not restricted to gaze. For example, when the user 190 wears a controller in hand, when the user's hand indicates the model, the server 150 is interested in the clothing of the model based on the signal from the controller. You may judge that you Or user 1
Based on 90 cheering on the model, server 150 may determine that user 190 is interested in the model's clothing. In yet another aspect, the HMD
If the camera 190 can capture the face of the user 190, the server 150 determines that the user 190 is interested in the clothes of the model based on the change in the user's expression. Good.

In step S2330, the processor 151 selects the user 19 for a predetermined fixed time.
It detects that the line of sight of 0 is directed to the clothes.

In step S2335, the processor 151 presents detailed information in the vicinity of the model object 1840 in the virtual space 2. The virtual camera 1 acquires a view image in which detailed information is presented, and the server 150 transmits data of the view image to the computer 200. When the monitor 112 displays an image based on the data, the user 190 visually recognizes that the detailed information is expanded in the vicinity of the model object 1840.

In step S2340, the processor 151 acquires the degree of interest according to the time when the gaze is directed. In one aspect, when one user 190 is enjoying a fashion show, the processor 151 calculates, as the degree of interest, the ratio between the time when the user 190 is looking at and the predetermined reference time. .

In step S2350, the processor 151 stores the degree of interest in the storage 154.

In step S2355, the processor 151 determines whether an order for clothes has been received from the user 190. If processor 151 determines that an order for clothes has been received from user 190 (YES in step S2355), it switches control to step S2360. If not (NO in step S2355), processor 151 switches control to step S2370.

In step S2360, processor 151 executes order processing and charging processing using the information sent from computer 200 based on the operation of user 190. The information sent from the computer 200 includes the identification number of the user 190 and the identification number of the ordered item (
The identification number of the clothing worn by the model object 1840), a credit card number, and the like. The order process includes transmitting the identification number of the garment selected by the user 190 and a code representing the order to the supplier of the garment. The charging process includes charging the user 190 for clothes and paying the clothes purchase price to the supplier.

In step S2370, the processor 151 records in the history DB that the order has not been reached. For example, the processor 151 sets the value of the order history 2133 for the clothes to 0 in the table 2130.

In step S2375, the processor 151 generates an image in which the next model wears another clothes in the virtual space 2. When the virtual camera 1 captures the image, data is transmitted from the server 150 to the computer 200, and the HMD 110 displays the image on the monitor 112 based on the data.

In step S2380, the processor 151 determines whether to continue the VR fashion show based on the next model. When determining that the VR fashion show based on the next model is to be continued (YES in step S2380), the processor 151 returns the control to step S2325. If not (NO in step S2380), processor 1
51 ends the process.

Referring to FIG. 24, a phase in which another coordinated fashion show is performed will be described. FIG. 24 is a flowchart showing a part of the process performed in the aspect. The same step number is attached to the same process as the above-mentioned process. Therefore, the description of the same process will not be repeated.

In step S2410, the processor 151 reads data of clothes that have not been ordered from the history DB and causes the model to wear them. More specifically, for example, the processor 151 refers to the order history 2133 of the table 2130 and extracts a record whose value is 0. The record includes a model ID 2131 and a clothing ID 2132. Processor 1
51 is a model ID different from the model ID 2131 specified in the extracted record,
For example, identification is performed in descending order or in ascending order, and an image is generated in which the model identified by the identified model ID is caused to wear the clothing identified by the clothing ID 2132. The server 150 transmits data for displaying the image to the computer 200. The monitor 112 displays the image based on the data. As a result, clothes not ordered by other models are presented again to the virtual space 2 by another model, so coordination with the other model is realized.

In step S2470, the processor 151 generates an image in which the next model wears the clothes.
