Systems and methods for tracking the position of a head-mounted display (HMD) system component. The HMD component may carry a plurality of angle sensitive detectors that are able to detect the angle of light emitted from a light source. The HMD component may include one or more scatter detectors that detect whether light has been scattered or reflected, so such light can be ignored. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of angle sensitive detectors. The processor may process the sensor data and scatter detector data, for example using machine learning or other techniques, to track a position of the HMD component. An angle sensitive detector may include a spatially-varying polarizer having a position-varying polarizing pattern and one or more polarizer layers that together are operative to detect the angle of impinging light.

An object is displayed in a three-dimensional virtual reality environment so that a first user can view an avatar of a second user in a non-obstructive form when the avatar of the second user would otherwise obstruct a view of the object from the first user.

Disclosed are systems and methods for generating a walkable 360-degree video or virtual reality (VR) environment. 360-degree video data is obtained for a real-world environment and comprises a plurality of chronologically ordered frames captured by traversing a first path through the real-world environment. One or more processing operations are applied to generate a processed 360-degree video, which can be displayed to a user of an omnidirectional treadmill. Locomotion information is received from one or more sensors of the omnidirectional treadmill, wherein the locomotion information is generated based on a physical movement on or within the omnidirectional treadmill. Using the received locomotion information, one or more playback commands for controlling playback of the processed 360-degree video are generated. One or more selected frames of the processed 360-degree video are rendered for presentation and display to the user, based on the one or more playback commands.

An information processing method is provided for a terminal device. The method includes obtaining an image including an AR target; recognizing the AR target, and generating a virtual scene including N virtual objects (N being an integer greater than or equal to 2); disassembling the virtual scene to obtain the N virtual objects; and generating object information that separately corresponds to the N virtual objects, which include a target virtual object to be interacted with by a user. The method also includes keeping the object information of virtual objects other than the target virtual object in the N virtual objects unchanged and updating the object information of the target virtual object in response to receiving an operation instruction inputted by the user for the target virtual object, such that the target virtual object is interacted independently rather than the virtual scene as whole by the user.

A VR training system includes: training terminals that generates simulation images for simulation training in common VR space and provides the simulation images to trainees individually associated with the training terminals; and a tracking sensor that detects motion of the trainees in real space. Each of the training terminals calculates a position and a posture of a self avatar in VR space based on a detection result of the tracking sensor, acquires position information on a position and a posture of another avatar in the VR space from another training terminal, and generates the another avatar in the VR space based on the acquired position information.

A method and apparatus is disclosed for assisting a user, wearing a head mounted display (HMD) that covers a user's field of vision and has a tracker providing information regarding the position and orientation of the HMD, in locating a physical controller located on a physical base station. A processor causes the HMD to display a virtual world, including a virtual representation of the physical base station and physical controller along with a virtual hand that helps guide the user to the physical base station to allow the user to pick up the physical controller. Another embodiment allows an area in the physical world to be defined within which the user should remain, for example to avoid physical obstacles. The processor causes the HMD to display a warning, such as a virtual fence, to alert the user if the user approaches to within a preselected distance of the boundary.

A variable-resistance exercise machine with wireless communication for smart device control and interactive software applications, comprising a wireless network interface that receives input from a user device and provides output to a user device; a plurality of moving surfaces that each provide an independent degree of resistance to movement based on received input and that detect movement and provide output to a user device based on the movement; and a plurality of rigid rails that provide a rigid support for a human user to grasp, and that provide attachment points for a user to affix a variety of devices.

A method for generating a limitless path in a virtual reality environment (VR) for a continuous locomotion within a real physical space using Head-Mounted-Display (HMD) device associated with a user is provided. The method includes determining a line segment between two points that corresponds to an initial path travelled by the user. The method includes detecting a boundary of the VR environment to generate a next line segment. The method includes generating and adding a new line segment to end of the initial path. The method includes generating and adding the new line segment to the end of the next line segment. The method includes generating an updated path by adding the new line segment in a direction at the angle of shift angle to the direction of the next line segment. The method includes, configuring to output updated path as two-dimensional points to render updated path into VR environment.

A method of providing a virtual space. The method includes defining a virtual space by a processor. The method further includes displaying a field of view of the virtual space on a head mounted display device. The method further includes detecting, by the processor, a motion of the user wearing the head mounted display device. The method further includes determining, by the processor, a flying direction for an object in the virtual space in response to the detected motion. The method further includes flying, by the processor, the object within the virtual space in accordance with the flying direction. The method further includes moving, by the processor, the field of view in the flying direction.

The present disclosure provides a centralised virtual and augmented reality activity system comprising a plurality of co-located virtual reality suites, each fully equipped with virtual reality accessories and set in an environment that is safe and spacious. The user devices of each suite are managed by a central server, also in the same location, which allows for interactions both between users of the different suites and facilitates normal interaction between the user devices and the internet.
