A visual field information collection method is capable of collecting visual-field information of a user wearing a head mounted display without applying a large calculation load to a processor. The visual-field information collection method to be executed by a processor includes arranging, in a virtual space in which a user wearing an HMD is immersed, a virtual camera that defines a visual axis for specifying a visual field of the user. The method includes determining the visual axis in accordance with one of a movement of the HMD and a line-of-sight direction of the user. The method includes determining whether or not the visual axis is moved from a predetermined first position to a predetermined second position. The method includes generating movement information representing that the visual axis is moved when the visual axis is moved from the predetermined first position to the predetermined second position.

A system configured to be coupled with a participant of an activity. The system comprises: a participant activity monitoring unit configured for monitoring a performance of the activity by the participant; an activity information module configured for storing performance information corresponding to the activity; and a participant performance correlator configured for delivering comparative performance data based on the monitored performance of the activity by the participant and the stored performance information.

The present disclosure relates to a method (40) performed in a system (10) for handling a media stream relating to an online game provided by a game cloud system (20). The system (10) comprises at least one node (11, 12). The method (40) comprises transmitting (41), to the game cloud system (20), a message comprising data relating to at least one virtual camera, and receiving (42), from the game cloud system (20), at least one first media stream relating to the online game as captured by the at least one virtual camera. The disclosure also relates to a corresponding system, computer programs and computer program products, and also to method in a game engine and a game engine.

An in-game display control method and apparatus, a storage medium, a processor, and a terminal are provided. The method includes that: a touch area is configured on a graphical user interface; in response to a first touch operation acting on the touch area, a movement of a preset virtual character in a game scene is controlled according to the first touch operation; a scene display area is updated according to a first position of the preset virtual character in the game scene; whether a preset specific event exists in a preset area of the first position is detected; when the specific event is detected to exist in the preset area of the first position, event attribute information of the specific event is acquired; and the scene display area in the game scene is updated according to the event attribute information.

A method of retargeting camera motion is disclosed. Data is received that describes a position of a target along a target path. Data is received that describes a position and an orientation of a first camera along a first camera path wherein the first camera is filming the target. A second camera path is computed, the second path corresponding to a second camera. The second camera path corresponds to the first camera path with one or more exceptions. The one or more exceptions include one or more of modification of orientation data corresponding to the second camera path to place the target at the center of a camera screen associated with the second camera and removing of a camera rotation roll for the second camera. A difference is computed between the first camera path and the second camera path. The computed difference is applied to a third camera path.

To enable you to take animations in a virtual space, an animation production method comprising: a step of placing a character in a virtual space; a step of placing a virtual camera for shooting the character in the virtual space; a step of acquiring action data defining an action of the character from an external source; a step of operating the character based on the action data; and a step of shooting the action of the character by the camera.

An example game device corrects a sound of a sound source located behind a virtual camera by applying a frequency filter to the sound. Specifically, an angle between an imaging direction of the virtual camera and a direction from the virtual camera toward the sound source is calculated. If the absolute value of the angle is 90 degrees or more, a filter value is calculated based on the angle. The game device also corrects the filter value based on a distance between the virtual camera and the sound source. The game device applies a low-pass filter corresponding to the filter value to the sound of the sound source.

An example game system includes a controller device, and a game process section for performing a game process based on an operation on the controller device. The controller device includes a plurality of direction input sections, a sensor section for obtaining a physical quantity used for calculating an attitude of the controller device, and a display section for displaying a game image. The game process section first calculates the attitude of the controller device based on the physical quantity obtained by the sensor section. Then, the game process section controls an attitude of a virtual camera in a virtual space based on the attitude of the controller device, and controls a position of the virtual camera based on an input on the direction input section. A game image to be displayed on the display section is generated based on the position and the attitude of the virtual camera.

A processing apparatus includes: an input interface configured to receive from a user an input for controlling a movement route of a virtual object arranged in a virtual game space; a memory configured to store arrangement information in the virtual game space and computer readable instructions, the arrangement information being associated with the virtual object; a display configured to display predetermined information; and a processor configured to arrange the virtual object at a predetermined position in the virtual game space based on the arrangement information stored in the memory, calculate a predicted route, along which the virtual object will move from the predetermined position, based on the input via the input interface, and output the predicted route to the display.

An information processing device for drawing an object arranged in a three-dimensional virtual space, in an expression viewed from a virtual camera, the object including a field object associated with a two-dimensional plane defined by a first axis and a second axis, and a specific object arranged on the field object, the device including: a change processing unit changing a region of the field object falling within a viewing angle of the virtual camera; and a deformation processing unit deforming the field object, in which in a case where the region is changed by the change processing unit, the deformation processing unit makes a deformation mode of the field object different when it is determined that the specific object is positioned in the region after being changed and when it is determined that the specific object is not positioned in the region after being changed.
