Teleportation (in VR)
Teleportation in VR is a locomotion method allowing users to move instantly to a designated spot within the virtual environment. It's significant as it helps in avoiding motion sickness and allows for easier navigation in VR spaces.
Spatial Audio
Spatial audio in VR refers to sound that changes in real-time as the user moves through a virtual environment, providing a 3D auditory experience. It significantly increases immersion and aids navigation within VR.
Tracking Systems
Tracking systems in VR refer to the technology used to monitor the position and orientation of the user and the VR equipment. These systems are significant because they enable realistic and responsive movements within the VR environment.
Eye Tracking
Eye tracking technology in VR detects and follows eye movements, allowing the VR system to adjust content based on where the user is looking. This is significant for improving user interaction and enabling foveated rendering.
Frame Rate
Frame rate refers to the number of individual frames or images that are displayed per second in VR. A high frame rate is significant for a smooth and realistic VR experience.
Presence
Presence in VR is the feeling of being physically present in a non-physical world. It is significant because it enhances user engagement and the overall VR experience.
VREngine
VR Engine, also known as a game engine tailored for VR, provides development tools and software specifically designed for creating virtual reality content. Engines like Unreal and Unity are significant for simplifying VR development.
Chaperone System
A chaperone system is a safety feature in VR that displays boundaries of the real-world play area to prevent users from walking into physical objects. It is significant for preventing accidents and maintaining user safety while immersed.
6DOF
Six Degrees of Freedom (6DOF) refers to the freedom of movement in a 3D space that includes forward/backward, up/down, left/right translation, as well as roll, pitch, and yaw rotations. It's crucial for creating a realistic VR experience as it allows users to move naturally.
Foveated Rendering
Foveated rendering is a technique that renders the highest quality image in the area where the user's gaze is focused while reducing the quality in the peripheral vision. This is significant in VR as it reduces the processing load and improves performance.
HMD
Head-Mounted Display (HMD) is a device worn on the head with a display in front of the eyes to provide immersive virtual experiences. It is significant in VR as it delivers the visual aspect of the immersive environment.
Latency
Latency in VR is the delay between a user's action and the displayed response. Low latency is vital to prevent motion sickness and ensure a comfortable and convincing VR experience.
