Description

  The present invention relates to a technique for presenting an image of a three-dimensional virtual space, and more particularly to a method for controlling information to be presented.

With regard to an apparatus for presenting an image in a three-dimensional virtual space, there has conventionally been a technique for controlling virtual information to be presented according to an attribute of an observer. For example, Patent Document 1 proposes a technique for reproducing the sight of different heights based on the height of an observer (presenting a child's field of view to an adult).
JP-A-5-282279

  As in the prior art described above, the control method that depends only on the attributes of the device user cannot optimally control the content presented to the user. For example, consider a case where confidential three-dimensional shape data is observed on a head-mounted display (hereinafter referred to as an HMD) or a normal two-dimensional display such as a liquid crystal monitor (hereinafter referred to as a 2D display). Assume that the user of the device is a party authorized to observe confidential data or an outsider who does not have the authority to observe.

  When interested parties observe shape data on a 2D display, if confidential data is presented on the display considering only the attributes of the device user (= related party), outsiders will look into the display and leak confidential information. There is a risk of doing. Therefore, when a 2D display is used, data to be presented must be limited even if the observer is a participant. On the other hand, since it is difficult for a person other than the observer to see the presented image, the HMD can safely present confidential information if the observer is a related person.

  As shown in this example, the information to be presented is optimally controlled (in the above example, both the convenience for the parties to access the confidential information and the safety to prevent the information from leaking to outsiders) Therefore, it is necessary to consider user attributes and device attributes in combination. However, there has been no such technique in the past.

  The present invention has been made in view of the above problems, and provides an image presentation apparatus and method capable of controlling the presentation of information to a user by a display device in accordance with the combination of the user and the display device.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to control presentation of the information to a user by a display apparatus according to the combination of a user and a display apparatus. In particular, by applying the present invention to an apparatus that presents an image in a three-dimensional virtual space, it becomes possible to present an image in consideration of security, the influence on the health of the observer, and the like.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<First Embodiment>
In the first embodiment, in order to ensure the security of the three-dimensional shape data, an example in which the content to be displayed is controlled according to the attribute of the user and the display device used for the user to observe the data will be described. It is assumed that the three-dimensional shape model displayed in the present embodiment is that of the automobile under design and includes top-secret parts.

  In addition, the user who observes this model is assumed to be an employee and an employee of a cooperating company, but in order to ensure security, the details of the shape are not shown except for the employee. Further, it is assumed that only a part of employees (for example, managers) can observe the top secret parts even if they are employees.

  As the display device, a head-mounted display (HMD) and a normal two-dimensional display (2D display) are used. When using the HMD, only the user wearing the HMD can observe the image. On the other hand, since the 2D display can be viewed by a screen other than the main user, information to be displayed must be limited in consideration of security rather than the HMD. It should be noted that an operation of observing a model (model movement / rotation, etc.) is performed by an employee of an outside contractor while viewing the 2D display.

  From the background as described above, in the present embodiment, the contents to be displayed based on the type of display device (HMD / 2D display) as the attribute of the device and the presence / absence of the post as the user attribute and the attribute of the device in the present embodiment. Control.

  FIG. 1 is a diagram illustrating an example of display content control of the image presentation device according to the first embodiment. As shown in FIG. 1, employees and managers can observe the detailed shape of the entire model including the top secret parts with the HMD and the simple shape of the model excluding the top secret parts with the 2D display. In addition, employees and non-executives can observe the detailed shape of the model excluding the top secret parts with the HMD and the simple shape of the model excluding the top secret part with the 2D display. Further, when an employee of an outside contractor observes, the HMD does not display a model but displays only a simplified shape on a 2D display. The reason why the simplified shape is displayed here is that a minimum amount of information is required to confirm the operation result of the model.

As described above, in the present embodiment, the degree of data concealment is controlled based on the user attribute and the device attribute. In the following, this degree of data secrecy is represented by a five-stage numerical value called “security level” (the degree of secrecy is low: 1 to the degree of secrecy is high: 5). That is, the display state corresponding to each security level is as follows.
・ Security level = 1: Detailed shape including top secret parts,
・ Security level = 2: Detailed shape excluding top secret parts,
-Security level = 3: Simple shape excluding top secret parts,
-Security level = 4: Simplified shape,
-Security level = 5: Not displayed.

  Next, an outline of the configuration of the image presentation apparatus according to the present embodiment will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a user attribute acquisition unit that acquires user attributes by inputting personal authentication data output from a display (head mounted display (HMD) 205 in FIG. 2), that is, user authentication information. A device attribute acquisition unit 202 receives, for example, a signal (display identification signal) representing a display type output from a display (a head-mounted display (HMD) 205 in FIG. 2) as an input, and acquires device attributes. That is, the device attribute acquisition unit 202 acquires the attribute of the display device based on the device information of the display device used for image display.

  A presentation information control unit 203 determines information to be presented to the user based on the user attributes and device attributes acquired by the user attribute acquisition unit 201 and the device attribute acquisition unit 202. An image generation unit 204 creates an image reflecting the content determined by the presentation information control unit 203 and outputs the image to a display (the head mounted display 205 in FIG. 2). That is, the presentation information control unit 203 and the image generation unit 204 change the display content by the display device based on the combination of the user attribute and the attribute including the device attribute obtained from the user attribute acquisition unit 201 and the device attribute acquisition unit 202. Is. For example, as will be described later, the display contents are changed depending on whether the display device is an HMD or a 2D display. Therefore, in addition to the function of displaying the image output from the image generation unit 204, the display used in this calibration has a function of outputting personal authentication data for specifying an observer and a function of outputting a display identification signal. I have.

  Furthermore, the detail of a structure of an image presentation apparatus is shown in FIG. Note that the image presentation apparatus of the present embodiment can also be realized by an information processing apparatus such as a general-purpose computer.

  In FIG. 3, reference numeral 301 denotes a CPU which controls the operation of the entire apparatus. A memory 302 stores programs and data used for the operation of the CPU 301. Each unit illustrated in FIG. 2 is realized by the CPU 301 executing a program stored in the memory 302. Reference numeral 303 denotes a bus, which controls data transfer between each component module. An interface 304 connects the bus 303 and various devices. Reference numeral 305 denotes an external storage device that stores programs and data to be read into the CPU 301. Reference numeral 306 denotes a keyboard, and reference numeral 307 denotes a mouse, which constitutes an input device for the user to specify program activation and program operation. The display unit 308 displays the operation result of the process. The display unit 308 is an HMD or a 2D display, and a fingerprint information acquisition unit 309 is attached to both the HMD and the 2D display. The fingerprint information acquisition unit 309 is also connected to the interface 304 in the same manner as the display unit 308, and when a person using the apparatus touches the finger, the fingerprint shape of the person is read and the apparatus is used as personal authentication data. To enter. As will be described later, an image of the three-dimensional virtual space is not displayed unless the person is authenticated as a registered user from the fingerprint of the user of the apparatus. Therefore, the user of the apparatus must always input fingerprint information before observing the image.

  Next, the flow of the entire process by the image presentation apparatus according to the first embodiment having the above configuration will be described with reference to FIG.

  When the process is started, the CPU 301 initializes data necessary for the process in step S401. More specifically, the user attribute on the memory 302 is set as belonging = “external contractor employee”, job title = “none”, the device attribute is set at display type = “2D display”, and the security level is set at “5”. To do. The CPU 301 reads a three-dimensional shape model data file, a user attribute data file, a security level determination data file, and a display device data file from the external storage device 305 and stores them in the memory 302. Details of these data files will be described later.

  Subsequently, the device attribute acquisition unit 202 acquires device attributes in step S402, the user attribute acquisition unit 201 acquires user attributes in step S403, and the presentation information control unit 203 determines the presentation contents in step S404. In the present embodiment, information to be used for display according to the combination of attributes acquired in steps S402 and S403 from information (shape data) prepared in advance according to a plurality of combinations of user attributes and device attributes. Selected. Details of these steps S402, S403, and S404 will be described later.

  In step S405, the image generation unit 204 generates a projection image of the virtual object to be presented to the user according to the presentation content determined by the presentation information control unit 203 in step S404. In step S <b> 406, the image generation unit 204 outputs the generated image to the display unit 308. For example, in the configuration illustrated in FIG. 2, the HMD 205 is connected as the display unit 308, and the image generation unit 204 outputs the generated image to the HMD 205. Note that the virtual image generation processing in step S405 can use a known method in computer graphics, and a detailed description thereof will be omitted.

  In step S407, it is determined whether or not there has been an operation for instructing the end from the user. If there is an end instruction, the process ends, and if not, the process returns to step S405. In determining the end instruction, for example, a specific key on the keyboard 306 may be assigned to the end instruction, and it may be determined whether or not the key is pressed.

  Next, the contents of the data file read in step S401 will be described.

  FIG. 5 is a diagram schematically showing a configuration of a three-dimensional shape model data file including one virtual object. The data file 501 includes an object delimiter 502 representing the start of data of one object, and shape data sets 503 and 505 for each security level. Here, the shape data set 503 is a security level 5 shape data set, and the shape data set 505 is a security level 1 shape data set. The shape data sets of security levels 2 to 4 are also stored in the same format. Each of the shape data sets 503 and 505 includes security level delimiters 506 and 508 representing the start of the security level and shape model data 507 and 509 corresponding to each security level.

  The image presentation apparatus of this embodiment loads the data file 501 having the configuration shown in FIG. 5 and accumulates shape model data corresponding to the security level in the memory 302. When there are a plurality of models, a file in which a plurality of groups of shape data sets having the configuration 501 are continuously read is read.

  Next, the user attribute data file will be described. FIG. 6 is a diagram showing a data configuration example of the user attribute data file according to the present embodiment.

  One user attribute data file 601 is composed of a plurality of user data sets 602 and 604. Each user data set includes fields of a user delimiter 605 indicating the start of user data, fingerprint information 606 for each person to be collated with information input from the fingerprint information acquisition unit 309, an affiliation 607, and a title 608. In the field of affiliation 607, information on whether the user is an employee or an employee of an external company is described. In the field of title 608, the presence or absence of the title of the user is described. The image presentation apparatus according to the present embodiment loads the user attribute data file 601 having the above configuration and constructs a user attribute database on the memory 302.

  The security level determination data file describes security levels according to user attributes and display device attributes. 7 and 8 schematically show the contents of the security level determination data file of the 2D display when the display device is an HMD. For example, in the HMD security level determination data file (FIG. 7), the security level is described as “1” when the user attribute is “affiliation = employee” and “position” = exist. Further, in the security level determination data file (FIG. 8) of the 2D display, when the user attribute is “affiliation = employee” and “position” = exist, the security level is described as “3”. The image presentation apparatus according to the present embodiment reads a security level determination data file in step S 401 and constructs a security level determination database on the memory 302.

  The display device data file is used to know the type (HMD / 2D display) from the display type. FIG. 9 is a diagram schematically showing the contents of the display device data file. For example, if the model information received from the display connected to the interface 304 indicates model A, the display type is determined to be HMD. Similarly, if the model information received from the display connected to the interface 304 indicates model B, the display type is determined to be a 2D display. The image presentation apparatus according to the present embodiment reads a display device data file as shown in FIG. 9 in step S 401 and constructs a display device database on the memory 302.

  Next, details of the device attribute acquisition process (step S402) will be described. FIG. 10 is a flowchart showing the flow of device attribute acquisition processing.

  When the process is started, in step S1001, the device attribute acquisition unit 202 inputs a display identification signal (that is, model information) from the display device, and determines the display model. In step S1002, the device attribute acquisition unit 202 searches the display device database for the model determined in step S1001, and determines whether there is a corresponding model in step S1003.

  If it is determined in step S1003 that the corresponding model exists, in step S1004, the device attribute acquisition unit 202 sets the display type that is the device attribute to the type of the corresponding model that is the search result. For example, when the display device database is constructed from the display device data file as shown in FIG. 9 and the display model is A, the display type is set to “HMD”. If the display model is B, the display type is set to “2D display”.

  If it is determined in step S1003 that the corresponding model does not exist, in step S1005, the device attribute acquisition unit 202 sets the display type to “2D display”. Here, the reason why the display type is set to “2D display” when there is no corresponding model is that it is stricter in security than the HMD and is suitable for the purpose of safely concealing data.

  Next, details of the user attribute acquisition processing in step S403 will be described. FIG. 11 is a flowchart showing the flow of user attribute acquisition processing.

  When the process is started, in step S1101, the user attribute acquisition unit 201 determines whether fingerprint information has been input to the fingerprint information acquisition unit 309. That is, it is determined whether or not the user has performed a fingerprint authentication operation. If there is no input of fingerprint information, the process returns to step S1101.

  If it is determined in step S1101 that fingerprint information has been input, the user attribute acquisition unit 201 acquires fingerprint information from the fingerprint information acquisition unit 309 in step S1102. In step S1103, the user attribute acquisition unit 201 searches the user attribute database for the fingerprint information acquired in step S1102. In step S1104, the user attribute acquisition unit 201 determines whether a person corresponding to the fingerprint information is registered.

  If the corresponding person is registered in the user attribute database, in step S1105, the user attribute acquisition unit 201 sets the user's belonging attribute and title attribute to the corresponding person's belonging and title as a search result, and ends the process. . On the other hand, if the person corresponding to the user is not registered in the user attribute database, the process returns to step S1101 and the above process is repeated.

  As can be seen from the flowchart of FIG. 11, unless the user registered in the user attribute database is authenticated, the process does not proceed after the user attribute acquisition process (step S403), and thus the image of the three-dimensional virtual space is displayed on the display. It will never be done.

  Next, details of the presentation content determination process in step S404 will be described. FIG. 12 is a flowchart showing the flow of the presentation content determination process.

  When the process is started, in step S1201, the presentation information control unit 203 searches the security level determination database for the security level corresponding to the device attribute acquired in step S402 and the user attribute acquired in step S403. Next, in step S1202, the presentation information control unit 203 determines whether or not a combination of device attributes and user attributes corresponding to the database is registered by this search.

  If it is determined that it is registered, in step S1203, the presentation information control unit 203 sets the security level according to the search result. On the other hand, if it is determined that it is not registered, the security level is set to “5” in step S1204.

  In subsequent step S1205, the presentation information control unit 203 sets the display state of the shape model registered in the three-dimensional shape model data read in the initialization process (step S401). That is, the shape model of the security level set in step S1203 or step S1204 is set to the display state, and the shape model corresponding to other security levels is set to the non-display state. However, when the security level is 5, all the shape models are set to the non-display state.

  As described above, according to the first embodiment, the information to be displayed according to the combination (security level) of attributes acquired from information prepared in advance according to combinations of a plurality of types of user attributes and device attributes. The information to be selected is selected. For this reason, the image presentation apparatus can appropriately control the display contents according to the user attribute and the display device attribute, and can appropriately conceal the three-dimensional shape data.

  In the above description, fingerprint authentication is used as a means for identifying the individual user. However, the present invention is not limited to this. For example, any authentication method such as authentication using an iris pattern, a retina pattern, a vein pattern, a face image, or authentication using an ID card can be used.

  Further, a means for determining whether or not the user is observing the display device may be provided, and when a state where the user is not observing is detected, the personal authentication may be reset (a state where the user is not specified).

  In the above description, the attribute of the user and the presence / absence of the title are used as the user attribute. However, any other attribute may be used. For example, the security level is set to 4 or less for those who are in charge of designing or operating the apparatus as a job type, but the security level is set to 5 assuming that there is no authority to observe data for persons of other job types. It is possible to consider how to control. In the above embodiment, independent shape data is prepared for each security level, but a difference from shape data of a lower security level may be held. In this case, for example, when displaying at the security level 3, the shape data of the security levels 1 to 3 is used, and an image is generated.

  Furthermore, as the display device attribute, any attribute other than the model may be used. For example, considering the display installation location as an attribute, a configuration in which the security level is lowered when the installation location is a room that is difficult for outsiders to enter can be considered. Alternatively, when the resolution of the display is high, it becomes possible to observe data in more detail. Therefore, it is possible to control to increase the security level and increase the confidentiality.

Second Embodiment
In the first embodiment, an individual user is specified, and the user attribute is acquired by searching the user attribute database. However, the user attribute acquisition method is not limited to this, and any method can be used.

  For example, the user's attributes may be acquired by recording affiliation and job title information on an ID card possessed by the user and reading the information from the ID card. Similarly, any method can be used for acquiring the device attributes. For example, a device attribute may be obtained by printing a barcode representing a device type on a display device and reading the barcode with a barcode reader.

<Third Embodiment>
In the first embodiment, the target for controlling the presentation to the user is only the virtual space information, but the present invention is not limited to this. For example, information presentation in the real space may be controlled according to the security level. In the third embodiment, such an example will be described.

  In the case where the display includes an imaging device, a so-called mixed reality image in which an image of the real space photographed around the display and an image of the virtual space are fused can be presented to the observer. Here, when there is highly confidential information in the real space, it may be necessary to hide the information in the real space. As an example, there is a case where there is a mockup of an automobile designed in a real space, and for the sake of information security, the mockup shape cannot be shown to anyone other than those concerned.

  In the above case, it is determined whether or not an imaging device is provided as an attribute of the display, and it is determined whether the user is an employee or an outside contractor. When the display includes an imaging device and the user is an external contractor, the real space image is not displayed and only the virtual space is displayed. Alternatively, the real space image may be blurred by image processing and then combined with the virtual space image. As described above, according to the third embodiment, a display suitable for a combination of the attributes is provided by processing the information to be displayed based on the combination of the user attribute and the device attribute.

<Fourth embodiment>
In the current image display technology, it is known that long-time observation has adverse effects on the observer, such as eye fatigue. In particular, care must be taken so that the visual function does not adversely affect the developing child. In addition, when a stereoscopic image is observed, since the influence on the human body is great, further caution is required.

  Therefore, the image presentation apparatus according to the fourth embodiment has a configuration in which continuous observation time is controlled in consideration of age as a user attribute and presence or absence of a stereoscopic display function as a device attribute. In this embodiment, users are classified into groups under 12 years old (hereinafter referred to as “children”) and groups 12 years old and over (hereinafter referred to as “adults”), and the continuous observation time is limited as follows. Determine.

-User attribute = child and device attribute = 3D display function available: 10 minutes
-User attribute = adult and device attribute = 3D display function available: 15 minutes,
-User attribute = child and device attribute = no 3D display function: 20 minutes
User attribute = adult and device attribute = no 3D display function: 25 minutes.

  FIG. 13 is a flowchart illustrating a process flow of the image presentation apparatus according to the fourth embodiment. Note that the processing in FIG. 13 having the same reference numerals as those in FIG. 4 is the same as that in the first embodiment, and thus the description thereof is omitted.

  After performing the initialization process (step S401), the device attribute acquisition process (step S402), and the user attribute acquisition process (step S403), the presentation information control unit 203 starts measuring the continuous observation time in step S1301. After that, as described in the first embodiment, the presentation information control unit 203 determines the presentation content according to the security level determination result (step S404), and generates a virtual image according to the determined presentation content (step S405). .

  Next, in step S1302, the presentation information control unit 203 determines whether the continuous observation time is within a limit determined according to the user attribute and the device attribute. If it is determined that the limit is not exceeded, the process proceeds to step S406. If the limit is exceeded, the process proceeds to step S407. If the time limit is exceeded, step S406 is skipped, and no image is displayed. That is, if the observation is continued beyond the limit of the continuous observation time, the image is not displayed.

  As described above, according to the fourth embodiment, it is possible to adaptively reduce adverse effects on the living body according to the age of the user and the presence or absence of stereoscopic display.

  Note that it is also possible to consider visual acuity as a user attribute when determining the limit of the continuous observation time. For example, when the visual acuity falls below a predetermined threshold, the time limit is shortened by 5 minutes. In the above description, the content to be presented to the user (whether or not to present the virtual object image) is controlled. On the other hand, the device may be controlled. For example, a method of turning off the display device when the continuous observation time is exceeded can be considered.

  As described above, in the fourth embodiment, the display operation (restriction of continuous display time) by the display device is changed based on the combination of attributes including the user attribute and the device attribute.

<Fifth Embodiment>
In the fifth embodiment, a configuration will be described in which the angle of view for drawing a projected image of a virtual object is determined based on attributes of a user and a device. In this embodiment, two types of HMDs are assumed as devices. The types of these HMDs are different, and the angle of view in the vertical direction and the horizontal direction is determined by the optical design of the display unit. However, even if a projection image of a virtual object is created based on the design of the angle of view, there is a difference in how the size of the virtual object is felt by a person when the person observes with the HMD. Moreover, the way the size is felt varies depending on the HMD model.

  Therefore, in the fifth embodiment, an angle of view that gives a “size feeling” suitable for each user and each HMD model is measured in advance, and the angle of view is adaptively selected based on the measured angle.

  FIG. 14 is a flowchart showing the flow of processing by the image presentation apparatus of the fifth embodiment. The processing with the same reference numerals as in FIG. 4 is the same as that in the first embodiment, and the detailed description thereof is omitted.

  However, in the initialization process in step S 401, the CPU 301 reads an angle of view data file from the external storage device 305 and constructs an angle of view database as shown in FIG. 15 on the memory 302. As shown in FIG. 15, the field angle database stores a set of numerical values of the horizontal field angle and the vertical field angle in degrees for each combination of the individual user and the HMD model.

  In the device attribute acquisition process (S402), the device attribute acquisition unit 202 determines the HMD model based on the display device identification signal output from the HMD. In the user attribute determination process (S403), the user attribute acquisition unit 201 specifies the individual user by fingerprint authentication.

  In step S1401, the presentation information control unit 203 searches the angle-of-view database for the combination of the HMD model determined in step S402 and the individual specified in step S403. If there is a corresponding item in the view angle database, the horizontal and vertical view angles of the HMD are set according to the search result. On the other hand, if there is no corresponding item, the angle of view of the HMD is set to a standard angle of view according to the model.

  In step S405, the image generation unit 204 sets a virtual space range to be displayed based on the angle of view set in step S1401, and generates a projection image of the virtual object based on the set range. In step S406, the image is displayed on the HMD.

  According to the configuration of the fifth embodiment as described above, since the angle of view is adaptively set according to the user's individual sense and the HMD model, it is possible to give the user a sense of an appropriate size. .

  In the above description, the angle of view is adjusted for each HMD model, but may be adjusted for each HMD solid (for example, for each manufacturing number recorded in the HMD). By doing so, the sense of size can be controlled more strictly.

  In addition, when a certain tendency is seen in the angle of view for users belonging to a certain group, the angle of view may be set for each group instead of setting the angle of view for each individual user. For example, if the angle of view is divided between a man and a woman, the user's gender may be determined and acquired as a user attribute.

  In the above description, the angle of view is controlled as an image presentation condition on the display, that is, a drawing condition. However, other conditions may be controlled. For example, in the case of an HMD that can display a plurality of screens, it is conceivable to control the relative position and orientation between virtual cameras that draw each screen. Alternatively, in the case of an HMD equipped with an imaging device, the angle of view of the imaging device, the distortion parameters of the imaging system, the relative position and orientation of the imaging device and the display device, the gain and white balance of the imaging device, and the like may be controlled. it can.

<Sixth Embodiment>
In the image presentation apparatus according to each of the above embodiments, an arbitrary attribute can be used in addition to the above-described user attribute. Examples of such attributes include operation proficiency, hobbies, preferences, nationality, religion, and the like. The device attributes are also arbitrary.
