Methods, systems, and computer programs are presented for rendering images on a head mounted display (HMD). One method includes operations for tracking, with one or more first cameras inside the HMD, the gaze of a user and for tracking motion of the HMD. The motion of the HMD is tracked by analyzing images of the HMD taken with a second camera that is not in the HMD. Further, the method includes an operation for predicting the motion of the gaze of the user based on the gaze and the motion of the HMD. Rendering policies for a plurality of regions, defined on a view rendered by the HMD, are determined based on the predicted motion of the gaze. The images are rendered on the view based on the rendering policies.

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.

A game processing method executed by an information processing device includes switching a position of a virtual camera for generating an image of a first-person view point in a virtual three-dimensional space in a plurality of positions set in advance based on an operation input of a user. A direction of the virtual camera is controlled based on the operation input of the user. The direction of the virtual camera is corrected based on a positional relationship between a predetermined object present in the virtual three-dimensional space and the virtual camera when the position of the virtual camera is switched.

Handheld location based games are provided in which a user's physical location correlates to the virtual location of a virtual character on a virtual playfield.

Augmented Reality (AR) systems are provided in which video game indicia are overlaid onto a user's physical environment. A landscape detector is provided that may obtain information about the user's landscape, in addition to the user's location, in order to provide overlaying information to an AR head-mounted display and control information to non-user controlled video game characters.

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.

Embodiments of this application provide a virtual scene display method performed at a computing device. The method includes: obtaining animation data and video data; displaying an animation interface corresponding to the animation data in an animation display area of a display interface, the animation interface including a first virtual scene including a plurality of animation elements; and playing a video clip in the video data in response to an operation on the animation elements in the animation interface, the video clip presenting a picture of transformation from the first virtual scene to a second virtual scene. A virtual scene display solution provided in the embodiments of this application can reduce resource consumption of an intelligent device and reduce picture stutter.

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.
