DWANGO Co., Ltd.

Provided is a class system for taking a class conducted in an immersive virtual space by connecting a communication class server 10 and a student terminal 30 . The communication class server 10 comprises a delivery unit 103 that delivers, to the student terminal 30 , a class content for viewing a class being conducted in the virtual space, and a transmission unit 104 that transmits, to the student terminal 30 , a display signal, a non-display signal, an operation permission signal, and an operation prohibition signal respectively set according to the progress of the class. The student terminal 30 comprises a VR function unit 301 that disposes, in the virtual space, an avatar of a student that uses the student terminal 30 and controls the avatar, receives the class content, and displays the class content from the avatar's point of view, and an object control unit 303 that causes a teaching material object 500 to appear in the virtual space at a timing when the display signal is received, causes the teaching material object 500 to disappear at a timing when the non-display signal is received, enables the operation of the teaching material object 500 by the student at a timing when the operation permission signal is received, and prohibits the operation of the teaching material object 500 by the student at a timing when the operation prohibition signal is received.

An eye tracking system according to one embodiment includes at least one processor. The at least one processor is configured to: dynamically set a partial area of first content displayed on a screen as a guidance area to have a user gaze at the partial area; identify first viewpoint coordinates on the screen based on an eye movement of the user gazing at the guidance area; calculate a difference between the first viewpoint coordinates identified and area coordinates of the guidance area on the screen; and calibrate second viewpoint coordinates of the user viewing second content displayed on the screen by using the difference.

A class system for taking a class conducted in an immersive virtual space by connecting a communication class server and a student terminal. The communication class server includes a delivery unit that delivers, to the student terminal, a class content for viewing a class being conducted in the virtual space, and a transmission unit that transmits, to the student terminal, a display signal, a non-display signal, an operation permission signal, and an operation prohibition signal respectively set according to the progress of the class. The student terminal includes a VR function unit that disposes, in the virtual space, an avatar of a student that uses the student terminal and controls the avatar, receives the class content, and displays the class content from the avatar's point of view.

A student terminal is for viewing a class given in a virtual space that is immersive. The student terminal includes: a VR function section configured to display the virtual space according to virtual space information; and an input section for receiving a video capturing a desk of a student who views the class. The VR function section extracts, from the video, an area including a top plate of the desk corresponding to a desk object in the virtual space, and performs image composition for fitting a video capturing the area onto a top plate of the desk object.

A content provision system related to one embodiment includes at least one processor. The processor is configured to: generate action log information that records action information indicating an action of the first avatar operated while the first user views the content and specific action information indicating a timing of performance of a specific action by the first avatar and a detail of the specific action; reproduce the content along with an action of the first avatar based on the action information contained in the action log information, when a second user views the content after the first user viewed the content; and refer to the specific action information contained in the action log information and thereby arrange a display object that indicates the detail of the specific action in association with the first avatar at the timing of performance of the specific action by the first avatar being reproduced.

An eye tracking system according to one embodiment includes at least one processor. The at least one processor is configured to: dynamically set a partial area of first content displayed on a screen as a guidance area to have a user gaze at the partial area; identify first viewpoint coordinates on the screen based on an eye movement of the user gazing at the guidance area; calculate a difference between the first viewpoint coordinates identified and area coordinates of the guidance area on the screen; and calibrate second viewpoint coordinates of the user viewing second content displayed on the screen by using the difference.

Content distribution systems for displaying a virtual space to user terminals, content distribution methods executed by a content distribution system including at least one processor, and non-transitory computer-readable media storing a content distribution program are disclosed. An example system according to the disclosure includes at least one processor that detects when an avatar corresponding to a first user performs a predetermined action in a virtual space, and displays a content image of the virtual space on a user terminal of a second user among the plurality of user terminals. The predetermined action is invisible in the content image when the processor detects that the avatar performs the predetermined action.

A student terminal is for viewing a class given in a virtual space that is immersive. The student terminal includes: a VR function section configured to display the virtual space according to virtual space information; and an input section for receiving a video capturing a desk of a student who views the class. The VR function section extracts, from the video, an area including a top plate of the desk corresponding to a desk object in the virtual space, and performs image composition for fitting a video capturing the area onto a top plate of the desk object.

Provided is a program executable in a computer for viewing content. The computer includes a processor and a memory. The program causes the processor to execute generating a virtual space in response to an operation by a first user to designate content and setting a virtual viewpoint corresponding to the first user in the virtual space, starting reproduction of the content designated in the virtual space, and arranging, in the virtual space, at least one of an object pre-associated with the content or a second object corresponding to a second user who has viewed the content in the past. When the first user views the content, the object pre-associated or the second object is arranged at a position not related to a position of the virtual viewpoint of the second user in the virtual space or a position of the object pre-associated, when the second user viewed the content.

An avatar display device with: a storage device for storing passive permission data including a permission flag indicating permission or denial of a passive avatar in relation to an action of an active avatar with respect to the passive avatar; and an output unit which, if the action from the active avatar with respect to the passive avatar is detected, and the permission flag in the passive permission data indicates permission, outputs data for displaying, on an active terminal and a passive terminal, moving image data in which the passive avatar accepts the action of the active avatar.
