Eye Tracking
Eye tracking in VR is a technology used to detect where a user is looking within the virtual environment, allowing for improved control and rendering techniques.
Field of View (FoV)
Field of View in VR is the extent of the observable world seen at any given moment through the VR headset, important for immersive visuals.
Virtual Environment (VE)
A Virtual Environment is a digital space that simulates a physical presence in real or imagined worlds, commonly used for education and training.
Six Degrees of Freedom (6DoF)
6DoF refers to the freedom of movement in three-dimensional space that includes forward/back, up/down, left/right, and rotation around three perpendicular axes. Critical for realistic VR experiences.
Room Scale VR
Room Scale VR allows users to navigate a virtual environment by physically walking around in a designated space, tracked by sensors.
HMD
Head-Mounted Display (HMD) is a wearable device that contains a screen in front of the eyes to provide an immersive virtual experience. Commonly used in gaming and simulations.
Presence
Presence in VR is the psychological sensation of being in a virtual space, which is fundamental to the effectiveness of VR applications.
Mixed Reality (MR)
Mixed Reality combines real and virtual worlds to create new environments where physical and digital objects co-exist and interact in real-time, used in enhanced training simulations.
Spatial Audio
Spatial Audio in VR is a sound technology that imitates the way humans hear sounds in the real world, enhancing the realism of the virtual environment.
Latency
Latency in VR refers to the delay between a user's action and the corresponding visual feedback in the virtual environment, which can cause motion sickness if too high.
Telepresence
Telepresence in VR is the sensation of being physically present in a non-physical world, often used for remote meetings and collaboration.
Foveated Rendering
Foveated Rendering is a technique that reduces the workload on graphics processing by focusing on rendering high-resolution imagery only where the user's gaze is directed.
Locomotion
Locomotion in VR refers to the methods that allow the user to move through the virtual environment, including walking in place, teleportation, or joystick movement.
Avatar
An Avatar in VR is a digital representation of a user or player, which they can customize and control within the virtual environment.
Haptic Feedback
Haptic Feedback in VR involves tactile sensations through devices like gloves or controllers to simulate touch or interaction with virtual objects.
