Description

The present invention relates to a virtual reality or augmented reality reading system, a three-dimensional display control program for books and images, and an information processing method.

Using technology that defines virtual space and objects and displays them according to the viewpoint, VR (Virtual Reality) technology that provides users with experiences in virtual space, and AR (Argumented Reality) technology that displays virtual objects in the scenery of real space Reality) technology is known. In the use of VR technology and AR technology, especially by using a wearable display, a virtual space is expressed in the field of view of the user to provide a high sense of immersion.

On the other hand, the digitization of books is progressing, and there is a way to enjoy books easily without carrying the real thing. However, there is a demand not only for reading using electronic media, but also for a more free reading experience unique to electronic books.

Therefore, in recent years, a technique for displaying the content of an electronic book in virtual space is known. For example, Japanese Patent Application Laid-Open No. 2002-200003 describes a technique of using a virtual object as a display frame and further arranging a virtual object within the display frame, in which the display frame is represented as a page of a comic book.

Japanese Patent Application Laid-Open No. 2021-022207

With the technology described in Patent Document 1, by displaying comic pages as display frames in a virtual space provided by VR technology, users can enjoy reading in a free space. However, there is a problem that simply displaying the pages of a book as an image on an object gives a dull impression, which is greatly different from the impression when viewing a real book.

In view of the above circumstances, the present invention aims to provide a novel technique for realizing a natural reading experience in virtual space.

In order to solve the above problems, the present invention provides virtual reality or augmented reality reading for displaying a book object composed of a plurality of page objects in a virtual space, comprising a storage unit and a processing unit. The storage unit stores book information indicating the contents of a book, and the processing unit acquires page images of a plurality of pages constituting a book based on the book information, and obtains page images of two consecutive pages in the book. The page images are respectively rendered on both sides of the page object to display the book object based on a user's viewpoint.

With such a configuration, the page images are printed on both sides of the page object in the same way as the actual book, unlike the case where the page images are simply displayed in the form of a book. Therefore, the user can enjoy reading in the virtual space with a feeling closer to real reading. Specifically, for example, when the book object is viewed from a different perspective or when the page object is flipped, the page image rendered on the back side can be seen, giving the impression of looking at a real book. You can get a high sense of immersion.

In a preferred embodiment of the present invention, the book object is configured such that the sides of the plurality of page objects are in contact with each other at the position of the back cover, and the processing unit receives an instruction to turn a page and the page image is rendered. An animation of bending and turning the page object is displayed, and the page object with the page image of the next page rendered is displayed so as to open an adjacent page.

With such a configuration, page objects with page images rendered on both sides are displayed to move in the same way as the pages of a real book, providing a more natural reading experience.

In a preferred embodiment of the present invention, the processing unit receives an instruction to turn over a plurality of pages in succession, and has an animation in which the plurality of page objects having the page images rendered on both sides thereof are continuously warped and turned. display.

By adopting such a configuration, even when moving the viewing portion across a plurality of pages, the same expression as moving between pages in a real book is realized. Also, at this time, the page images are rendered on both sides of each page object, so instead of just displaying the "page-turning animation", the pages of the open book are turned continuously. It is displayed as if it goes on and on, and it is possible to give the user a higher sense of immersion.

In a preferred embodiment of the present invention, when receiving selection of a book to be expressed as the book object, the processing unit renders the page images of the book on both sides of each of a plurality of page objects.

Such a configuration eliminates the need for rendering each time the page is moved, thereby improving the display speed. This reduces the occurrence of phenomena that do not occur in reality, such as delays or stops in the movement of turning pages, or the display of page objects for which page images have not been rendered, resulting in a more realistic reading experience. can be provided.

In a preferred embodiment of the present invention, the processing unit renders a plurality of page images belonging to a predetermined range before and after the page on which the book object is opened, on the page object.

With such a configuration, a predetermined range near the currently opened page can be displayed immediately, so smooth display is possible even when many pages are moved. . In addition, by setting the range to be rendered to a predetermined range before and after the open page, it is possible to display quickly without impairing the sense of immersion even when memory is limited.

In order to solve the above problems, the present invention provides a three-dimensional display control program for books and images for displaying a book object composed of a plurality of page objects in a virtual space, comprising: a computer; The processing unit functions as a processing unit, the storage unit stores book information indicating the content of a book, the processing unit acquires page images of a plurality of pages constituting a book based on the book information, and the The page images of two consecutive pages in the book are rendered on both sides of the page object, respectively, and the book object is displayed based on the user's viewpoint.

In order to solve the above problems, the present invention provides an information processing method for displaying a book object composed of a plurality of page objects in a virtual space, wherein a computer stores book information indicating the content of the book, Acquire page images of a plurality of pages constituting a book based on the book information, render the page images of two consecutive pages in the book on both sides of the page object, and render the page images based on the user's viewpoint. Make the book object visible.

According to the present invention, it is possible to provide a novel technique for realizing a natural reading experience in virtual space.

The embodiments shown below are examples of the present invention, and the present invention is not limited to the following embodiments, and various configurations can be adopted.

For example, although the configuration, operation, and the like of a virtual reality or augmented reality reading system will be described in the present embodiment, similar configuration methods, devices, computer programs, and the like can also provide similar effects. Also, the program may be stored in a recording medium. Using this recording medium, a program can be installed in a computer, for example. Here, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM.

The present invention relates to a technique of displaying a three-dimensional book object by rendering a page image of a page included in an electronic book into a page object, which is a three-dimensional virtual object representing the shape of the page. In particular, in this embodiment, a wearable display that covers the user's field of vision is used to display a virtual space as a background, control the viewpoint of the virtual space according to the orientation of the user's face, and arrange book objects in the virtual space. displayed. Alternatively, instead of displaying a virtual background, an AR technique may be used that superimposes and displays a book object whose position is defined in the virtual space on a photographed image of the real space.

The electronic books handled in the present invention are not particularly limited, and various electronic books can be used regardless of various conditions such as content, number of pages, right opening, left opening, and the like.

The configuration of the virtual reality or augmented reality reading system according to this embodiment will be described with reference to FIGS. 1 and 2. FIG. In FIG. 1, a VR terminal 1 and a distribution device 2 are configured to be able to communicate via a network NW. The Internet or the like is assumed as the network NW. Note that the present invention may be configured by the VR terminal 1 alone.

As the VR terminal 1, it is possible to use any computer device equipped with a computing device such as a GPU (Graphics Processing Unit), a storage device, means for connecting to a network NW, various input/output devices including a display, and the like. . This embodiment assumes an integrated dedicated device with a GPU head-mounted display. Note that the VR terminal 1 of the present invention may be realized by using a smart phone or a tablet terminal and linking it with a wearable device. A dedicated application for functioning the arithmetic unit of the computer device as a processing unit described later, a browser application for accessing a dedicated web page, etc. are stored in the storage device, and the arithmetic unit executes various processes. , any computer device functions as the VR terminal 1 of the present invention.

The distribution device 2 includes a computing device such as a CPU or a GPU, a main storage device such as a RAM (Random Access Memory), an auxiliary storage device such as a HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, etc., a network A general computer device such as a server device having various input/output devices including means for connecting to the NW can be used. The distribution device 2 is a server that provides a service for distributing electronic books, and manages user information and electronic book information.

FIG. 2 is a diagram showing the functional configuration of the virtual reality or augmented reality reading system according to this embodiment. In this embodiment, the distribution device 2 includes a distribution unit 21 that distributes electronic book data in response to a request from the VR terminal 1, and a database 22 that stores the electronic book data. As described above, in the present embodiment, the distribution device 2 manages user information and electronic book data, and when a user purchases an electronic book, the right to use the electronic book specified in association with the user information of the user is granted. Electronic books are sold by registering information indicating that they are available. Then, when a distribution request is received from a user who has usage rights, the distribution unit 21 distributes the book data stored in the database 22 to the VR terminal 1 of the user.

Here, the information stored in the database 22 can be commonly used when general computers other than the VR terminal 1 in the system of the present invention browse books using a browser application or other book viewer application. . That is, the distribution device 2 may be, for example, a conventionally known general electronic book distribution server. , it is possible to enjoy purchased books in the VR space.

At this time, some of the electronic books sold by the existing system may not be permitted to be used on the VR terminal 1 . In this case, in the database 22, as the data of the book to be distributed, whether or not the book can be used in the VR terminal 1 of the present invention is stored. When the book is available on the VR terminal 1, the distribution device 2 distributes the book in response to a distribution request from the user.

The VR terminal 1 has a processing unit 11 and a storage unit 12 . It also has an output device such as a display and a speaker, and outputs the result of processing by the processing unit 11 . The VR terminal 1 transmits an electronic book distribution request to the distribution device 2, downloads the data of the book through user authentication, saves it in the storage unit 12, and the processing unit 11 displays based on the saved data. By executing the process, the book object is displayed. Note that the present invention is not limited to such a form. For example, a part or all of the processing unit 11 and the storage unit 12 are provided in the distribution device 2, and the display processing including rendering is performed in the distribution device 2. 1 may receive the display processing result from the distribution device 2 and display it on the display.

The storage unit 12 stores book information indicating the content of the book. In this embodiment, as book information, page images are stored for each of a plurality of pages that constitute a book. In addition to this, the book information includes various information related to the book, such as the title of the book, the number of volumes, the author, and the date of publication. Furthermore, it is preferable that a flag is set to the page that was open when reading of the book was last stopped, and the processing unit 11 displays the page from the page when the same book is opened next time.

Here, the storage unit 12 of the present embodiment stores the page image itself as book information, but the content to be expressed on the page of the book, that is, the information of characters and images for generating the page image is stored instead of the page image. may be stored. For example, there is a file format called so-called reflow type EPUB, in which the display amount and layout can be changed according to the screen size and resolution of the device used. The storage unit 12 may store such a reflowable EPUB file as book information, and the processing unit 11 may generate an image based on this, thereby obtaining a page image for each page.

The processing unit 11 acquires page images based on the book information stored in the storage unit 12, renders the page images of two consecutive pages in the book on both sides of the page object, and renders the book based on the user's viewpoint. Make the object appear on the display. In this embodiment, since page images for all pages are stored as book information, the processing unit 11 acquires page images from the storage unit 12 and renders them into page objects. That is, in the present embodiment, "obtaining a page image based on book information" refers to reading a page image included in the book information.

Specifically, first, a list of titles of books whose book information is stored in the storage unit 12 is displayed, and selection is accepted. FIG. 3 is a display example of a book selection screen. In this way, it is assumed that a bookshelf is displayed in a virtual space such as a library or a study, and books are displayed in a row on the bookshelf. In addition to the book whose book information is stored in the storage unit 12, the distribution device 2 displays a book registered with information indicating that the user has the right to use it, and when the book is selected, , the processing unit 11 may transmit a book distribution request to the distribution device 2 .

Here, for example, in the case of a series of books with a series of multiple volumes, such as the first and second volumes, in the list display, an image of the cover of one representative book, such as one volume of each title, is displayed. good too. When the selection of the title is accepted on the screen of FIG. 3, a plurality of books of the selected title, for example, volumes 1 to 10, etc., are displayed, and further selection can be accepted.

When a specific book is selected in this way, the processing unit 11 renders a plurality of page images centering on the page that was opened when browsing was stopped last time. When the book is opened for the first time, or when the book is closed after viewing up to the last page last time, the processing unit 11 performs display processing of the book object in a closed state with the front cover facing the user. .

Here, when a specific book is selected, the processing unit 11 renders all page images in a predetermined range before and after the page to be opened as a page object. For example, when opening the 200th page, page images of 100 pages before and after are rendered in the page object in this embodiment. That is, the page images from the 100th page to the 300th page are rendered into 100 page objects so that each continuous page is arranged on both sides.

Also, when the page is moved, that is, when another page is opened, the page image outside the predetermined range is rendered so that the rendering of the pages included in the predetermined range before and after each time is completed. Delete the data of the page object and render a new page image within the specified range. By rendering a plurality of page images at the time the book is opened in this way, it is possible to reduce display delays when pages are moved.

Here, the rendering process of this embodiment includes two processes: a process of converting a page image, which is binary data, into an image format and reading it into a memory; and a process of transforming the read page image in accordance with the shape of the page object. There are stages. In this embodiment, only the first stage of reading into memory is performed for a larger number of pages, for example, 150 pages before and after the page to be opened. Complete the combined transformation and display processing. As a result, even when the page is moved to a page that has not been completely rendered, it can be displayed by simply executing the second stage of transformation and display processing based on the data read into memory. This reduces processing delays.

Next, the display at the time of viewing an electronic book will be specifically described with reference to the drawings. When a specific book is selected as described above, the processing unit 11 executes display processing for switching from the virtual space at the time of book selection to another virtual space for reading. In this embodiment, multiple types of virtual spaces are registered in the storage unit 12, and the user can freely select and switch between them. It should be noted that a preferred virtual space may be registered according to the title of the book or each individual book, and the registered virtual space may be subjected to display processing.

FIG. 4 is a display example in which the processing unit 11 arranges the book objects BO in the virtual space in this embodiment. In this way, the book object BO of the present embodiment is represented by arranging the sides of the page objects PO so that they are in contact with each other, like a real book. When the pages are opened, two facing pages are placed in front with adjacent pages, similar to a real book. At this time, the page object is displayed in a flexed state that draws a curved surface due to the thickness of the bound book, and the page image rendered on the page object that draws the curved surface also exhibits distortion according to the situation. display is being processed.

A virtual space is displayed in the background, and the user can freely move in the virtual space and change the viewpoint by inputting instructions. The book object BO is arranged in the virtual space selected by the user, and the example in FIG. 4 shows an example in which a lawn environment is selected.

Here, the background can be changed arbitrarily. In this embodiment, the background is set in association with the book information indicating the content of the book, and the background is automatically selected according to the position of the book information being viewed, that is, the page opened in the book object BO. be done. Specifically, a background is stored in association with each page image, and the background is determined according to the opened page object. Alternatively, a background may be set for each unit such as a chapter or story.

In addition, for example, the background may be automatically switched according to the number of pages moved from the start of viewing, that is, the number of times the pages are turned. Alternatively, the background may be switched at predetermined intervals according to the elapsed time from the start of browsing, or the switching of the background may be determined by combining these conditions. Alternatively, for example, information on selectable backgrounds may be stored in the storage unit 12 in association with the book information, and the user may freely select from among the registered backgrounds.

When an instruction to turn a page is received on the book viewing screen as shown in FIG. 4, the processing unit 11 performs display processing of bending and turning animation of the page object in which the page image is rendered, and displays the animation on the display. Further, the page object in which the next page image is rendered is displayed on the display so as to open the adjacent page as it is. At this time, it is more preferable to reproduce a sound effect as if a paper book is being turned over.

FIG. 5 is a diagram for explaining page-turning display in this embodiment. FIG. 5 exemplifies a book that opens to the right, and the page number is displayed at the outer position of the double-page spread at the bottom of each page. When an instruction to go back one page from the state in which the 9th and 10th pages are displayed, that is, to turn over the page on the right side, the selected page object is transformed as shown in FIG. 5(a). The processing unit 11 performs display processing so that an animation of moving by pressing is displayed.

At this time, since page images are rendered on both sides of each page object visible from the user's point of view, the 9th page (side A) to be turned is also partially reversed. Also on the eighth page (side B), corresponding page images are displayed along the shape of the page object. Furthermore, the seventh page that appears when the page is turned is similarly arranged with the page image rendered in the page object, and the state of FIG. 5(a) smoothly transitions to the state of FIG. You can read the book object by moving pages in the same way as when viewing a real book.

As described above, a more natural reading experience can be provided by rendering page images on both sides of a page object and deforming and displaying the object in the same way as a real book. Various inputs such as book selection and page turning may be performed using a physical controller compatible with the VR terminal 1. A gesture may be recognized from an image, and the processing unit 11 may receive various inputs through gesture operations.

Gesture operations recognized on the book browsing screen will be described below with reference to FIGS. 6 and 7. FIG. FIG. 6 is a diagram showing an example of a gesture for inputting to move pages. FIGS. 6A to 6C are examples of gestures when turning pages one by one.

In the example of FIG. 6A, the user's fingers are detected from the captured image, it is determined whether each finger is extended, and if the index finger is extended and the middle finger, ring finger, and little finger are not extended, the gesture is recognized. Then, when the coordinates of the tip of the index finger move at a speed equal to or greater than a predetermined value, the processing unit 11 accepts this as an instruction to turn the page, and turns the page in the direction corresponding to the moving direction of the finger.

In the example of FIG. 6B, the user's finger is detected from the captured image, and the gesture is recognized when the finger is in contact with the book object at an angle within a predetermined range from the front of the book. When the gesture is recognized, the processing unit 11 accepts it as an instruction to turn a page, and turns the page touched by the user's hand.

Also, in the example of FIG. 6C, the user's fingers are detected from the captured image, and a pointer is displayed according to the position of the hand. Then, in a state in which the pointer is within the operation area at the left and right ends of the page indicated by dotted lines in FIG. is accepted as an instruction to turn a page. In this case, the direction of the page to be turned is determined by the position of the pointer.

FIGS. 6D and 6E are examples of gestures for successively turning over a plurality of pages. In the example of FIG. 6D, the fingers of the user are detected from the captured image, and the gesture is performed when the distance between the tip of the index finger and the thumb and the distance between the tip of the middle finger and the thumb are less than a predetermined value regardless of the position of the hand. to recognize Then, when a motion of rotating the hand is performed in the same manner as when a plurality of sheets of paper are piled up and flipped over, the processing unit 11 receives an instruction to turn over a plurality of pages in succession, The pages are turned continuously in the direction corresponding to the direction of rotation. Here, the processing unit 11 recognizes the rotation angle from the starting position of the gesture, and continuously executes page-turning display processing such that the greater the rotation angle, the faster the page-turning speed.

In the example of FIG. 6(e), similarly to FIG. 6(d), the gesture is recognized when the distances between the tips of the index finger and thumb and between the middle finger and thumb are less than a predetermined value. When this state is maintained for a predetermined time or longer, the processing unit 11 displays a slider as an operation unit, and when the user moves his or her hand left or right, the processing unit 11 continuously displays a plurality of pages. This is accepted as an instruction to turn over, and a plurality of pages are turned over continuously in the direction corresponding to the direction of movement. Here, the processing unit 11 recognizes the amount of movement of the slider, that is, the amount of movement from the start position of the gesture, and continuously executes page-turning display processing such that the greater the movement amount, the faster the page-turning speed. .

Note that in the present embodiment, when the gestures shown in FIGS. 6A to 6C are also recognized as continuing for a certain period of time or more, the processing unit 11 accepts an instruction to turn over a plurality of pages in succession, and performs a predetermined operation. Display processing is performed so that multiple pages are turned continuously at high speed.

Next, a gesture for inputting an instruction to move the book object will be described with reference to FIG. In the example of FIG. 7A, the fingers of both hands of the user are detected from the image, it is determined whether each finger is extended, and the state in which the index and middle fingers are bent is recognized as a "hold" gesture. When a "holding" gesture with both hands is recognized at the positions of both ends of the book object, the processing unit 11 accepts it as a movement instruction, and by moving the user's hand back and forth and left and right, the book object is moved in conjunction with the position of the hand. Display processing to move.

In the example of FIG. 7B, the fingers of both hands of the user are detected from the captured image, and the gesture is recognized when the distance between the index finger and the tip of the thumb is less than a predetermined value. Then, when a gesture is recognized for both hands, a pointer is displayed between the left and right fingers. When an action to change the distance between both hands is performed in that state, the processing unit 11 receives an instruction to enlarge or reduce, and changes the size of the book object according to the magnitude of the change in distance from the gesture recognition time. to process the display. Scaling refers to a change in the distance between the user's viewpoint and the book object in the virtual space. Enlargement corresponds to the user getting closer to the book object, and reduction corresponds to the user moving away from the book object.

The examples of FIGS. 7C and 7D show gestures for instructing movement with one hand. In this case, the user's fingers are detected from the image, it is determined whether each finger is extended, and the state in which the index and middle fingers are bent is recognized as a "hold" gesture. Then, when the "holding" gesture is recognized at the position of the edge of the book object, the processing unit 11 accepts it as a movement instruction, and by moving the user's hand back and forth and left and right, the book object is moved in conjunction with the position of the hand. Display processing to move.

Also, in the example of FIG. 7D, the user's fingers are detected from the captured image, and a pointer is displayed according to the position of the hand. Then, when the pointer is within the operation area near the center of the double-page spread shown by the dotted line in FIG. The processing unit 11 receives the movement instruction, and performs display processing so that the book object is moved in conjunction with the position of the hand when the user moves the hand forward, backward, leftward, or rightward.

As described above, by accepting various operations with movements similar to those of actual book reading, it is possible to further enhance the sense of immersion and provide a more natural reading experience.

Further, the VR terminal 1 of this embodiment has an automatic page-turning function that automatically turns pages at preset time intervals without requiring user's operation. User settings determine whether the automatic page-turning function is enabled or disabled, as well as its time interval.

When this function is enabled, the processing unit 11 generates and accepts an instruction to turn pages at set intervals by itself, and turns pages of the book object as described above. In this embodiment, as described above, various operations can be performed in a free posture without holding a device or controller. You can enjoy reading while exercising on a machine or lying down without moving your body.

On the other hand, when the amount of information varies from page to page, it is expected that there will be a desire to temporarily stop the automatic page-turning function even though it is basically used. Therefore, in the present embodiment, the processing unit 11 accepts an instruction to temporarily stop the automatic page turning while the automatic page turning function is enabled, and does not perform the page turning process while the instruction is being received. An instruction to pause automatic page turning may also be input by a controller or by a gesture. As a gesture operation for instructing to pause automatic page turning, for example, pointing a finger at a book object, touching a book object with an open hand, etc. are assumed.

As described above, according to the present embodiment, the book object can be displayed with the contents displayed on both sides of the page in the same way as a real book, thereby providing the user with a more immersive and natural reading experience. be able to. Furthermore, reading can be performed in a more flexible environment by accepting various instructions by gesture operations and automatically turning pages at predetermined intervals.
