Eye Tracking

StarStarStarStar

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.

StarStarStarStar

Field of View (FoV)

StarStarStarStar

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.

StarStarStarStar

Virtual Environment (VE)

StarStarStarStar

A Virtual Environment is a digital space that simulates a physical presence in real or imagined worlds, commonly used for education and training.

StarStarStarStar

Six Degrees of Freedom (6DoF)

StarStarStarStar

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.

StarStarStarStar

Room Scale VR

StarStarStarStar

Room Scale VR allows users to navigate a virtual environment by physically walking around in a designated space, tracked by sensors.

StarStarStarStar

HMD

StarStarStarStar

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.

StarStarStarStar

Presence

StarStarStarStar

Presence in VR is the psychological sensation of being in a virtual space, which is fundamental to the effectiveness of VR applications.

StarStarStarStar

Mixed Reality (MR)

StarStarStarStar

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.

StarStarStarStar

Spatial Audio

StarStarStarStar

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.

StarStarStarStar

Latency

StarStarStarStar

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.

StarStarStarStar

Telepresence

StarStarStarStar

Telepresence in VR is the sensation of being physically present in a non-physical world, often used for remote meetings and collaboration.

StarStarStarStar

Foveated Rendering

StarStarStarStar

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.

StarStarStarStar

Locomotion

StarStarStarStar

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.

StarStarStarStar

Avatar

StarStarStarStar

An Avatar in VR is a digital representation of a user or player, which they can customize and control within the virtual environment.

StarStarStarStar

Haptic Feedback

StarStarStarStar

Haptic Feedback in VR involves tactile sensations through devices like gloves or controllers to simulate touch or interaction with virtual objects.
