18 Virtual Reality Terminologies You Need to Know – Part I

1. Virtual Reality

Virtual Reality is a technology that creates an artificial and simulated environment, which can be similar or different from the real environment.

2. Head mounted display or HMD

Head mounted display or HMD is a common term used in the virtual reality world. It is the hardware that provides users the virtual reality experience. It can be either glasses/goggles, helmets, or headpieces.

3. Haptics

One of the exciting things about VR is that you try to reach out and "feel” something. This feedback is known as haptics.

4. Eye Tracking

The sensors in the VR headset carefully track your eye position, guiding you to a specific direction and image. This is called eye tracking. If you are playing a VR game, then eye tracking helps in delivering a real-life experience.

5. Head Tracking

Similar to eye tracking, tracking the position of the head in the VR experience helps you to look at the content from any direction. This is head tracking.

6. Motion Tracking

Motion tracking is the ability to track every movement made by the person wearing the VR headset. It helps you in closely aligning the person to the VR experience.

7. Field of View (FoV)

The Field of View (FoV) is the angle of the visual field. The higher the angle, the better the VR experience. The normal human eye reaches up to 200 degrees.

8. Blind Spot

Blind Spot is the area that the human eye cannot see. It is also the area of the content that cannot be displayed. Some VR headsets cuts off the display in the blind spot to save power.

9. Latency

Latency is the time taken by the VR headset to receive the trigger and update the display. In VR, the latency should be below 20 milliseconds for an immersive experience. If the latency is greater, then it can lead to motion sickness.
