Systems and methods are described for creating a non-curated viewing perspective in a video game platform based on a curated viewing perspective. For example, a user may be viewing a gameplay video of a video game. The user may be interested in viewing the same gameplay from a different perspective in the video game. Accordingly, a media guidance application may identify the video game in the video and retrieve video game engine data associated with the video game, to replicate, on a video game console, the gameplay depicted in the video. The user may be able to change the perspective (e.g., in-game position of the camera and the camera angle) within the replicated video game platform, via user commands. In response to receiving a user command to change the curated viewing perspective to a non-curated viewing perspective, the media guidance application may re-render the gameplay from the non-curated viewing perspective.

This application provides a mark processing method performed by a computer device. The method includes: displaying a display picture of a virtual environment; displaying an aiming prompt mark on the display picture of the virtual environment, the aiming prompt mark being used for indicating a target aimed position at which a target virtual object in the virtual environment aims; displaying a position prompt mark on the display picture of the virtual environment according to a first transparency, the position prompt mark being used for indicating a target environment position in the virtual environment; and adjusting the transparency of the position prompt mark in response to a change in relative positions between the aiming prompt mark and the position prompt mark.

An example of an image processing system includes a first HMD worn by a first user and a smart device carried by a second user. In a virtual space, a second virtual camera and a second object are placed in accordance with a position of the smart device relative to a reference in a real space. In the virtual space, a first object is placed regardless of a position of the first HMD in the real space, and a first virtual camera is placed at a position relating to a position of the first object. An image of the virtual space including the second object is displayed on the first HMD based on the first virtual camera. An image of the virtual space including the first object is displayed on the smart device based on the second virtual camera.

User action data characterizing action by a player in a game environment executing at a user client is received at a server. The game environment is created by the user client separate from the server. Data characterizing a selected viewing position is received. The selected viewing position is different than a player viewing position. The selected viewing position characterizes a viewing location within the game environment. A recreated game environment is generated from the user action data at the server. A video stream of the recreated game environment is generated. The video stream includes video from a perspective of the selected viewing position. The video stream is transmitted to a viewing client. Related apparatus, systems, articles, and techniques are also described.

A virtual reality game- and biosignal sensor-based VOR assessment and rehabilitation apparatus includes: a biosignal sensing unit which senses and notifies of head movement and eye movement of a patient using an eye tracker and an inertial measurement unit (IMU) sensor attached or installed to a head-mounted display device; a VOR function assessment unit which configures and provides a game for VOR function assessment; a patient-personalization control unit which determines, on the basis of the VOR gain of the patient, the types and order of rehabilitation games, and a rehabilitation level; and a rehabilitation game providing unit which configures and provides games for at least one among smooth pursuit, saccades, VOR rehabilitation exercise, amplified VOR rehabilitation exercise, and suppressive VOR rehabilitation exercise, and determines the difficulty levels of the games on the basis of the rehabilitation level.

A localization and tracking method, a localization and tracking platform, a head-mounted display system, and a computer-readable storage medium are provided. One or more images of odd frames and one or more images of even frames that are respectively collected with a preset first exposure duration and a preset second exposure duration by one or more tracking cameras arranged on a head-mounted display device are acquired, the one or more images of even frames at least containing blobs corresponding to multiple luminous bodies arranged on a gamepad; Degree of Freedom (DoF) information of the head-mounted display device is determined according to the one or more images of odd frames and attitude information of the head-mounted display device; and DoF information of the gamepad is determined according to the one or more images of even frames, attitude information of the gamepad, and the DoF information of the head-mounted display device.

A method of transforming a degree of freedom (DoF) in a multiple sensorial media (mulsemedia) system includes detecting, by a motion detector, a motion of an object to which motion effects are to be provided; calculating, by a motion proxy calculator, a motion proxy corresponding to the motion of the object; and transforming, by a transformer, the motion proxy into a motion command implementable within a motion range of a motion platform.

In some examples, an electronic device receives selection of a target image relating to an augmented reality presentation, displays, in a display screen of the electronic device, captured visual data of an environment acquired by the electronic device, and displays, in the display screen, guidance information relating to the target image to assist a user in finding a physical target, corresponding to the target image, in the captured visual data of the environment.

Techniques for creating more compelling augmented reality environments, and other computer-assisted experiences, are provided. In some embodiments, an augmented reality system, including a computer hardware- and software-based control system, controls a specialized headset and an array of sensors and actuators to produce an augmented environment with compelling display and social interaction features. In some embodiments, the augmented reality system creates and provides enhanced data access, permissions and experiences for users, based on different ratings of interactions between users. In some embodiments, a first such rating sets a level of access to gameplay leading to a second such rating. In some such embodiments, one user's experience related to another user is modified aesthetically, haptically or otherwise, depending on the levels granted by another user, among other factors.
