Question 1

What is the difference between virtual reality (VR) and augmented reality (AR)?

Accepted Answer

Virtual reality (VR) immerses the user in a fully digital environment through a headset, blocking out the real world. Augmented reality (AR) overlays digital elements onto the real world, typically via a smartphone, tablet, or smart glasses. Mixed reality (MR) combines both, allowing virtual objects to interact with the physical environment.

Question 2

What is extended reality (XR)?

Accepted Answer

Extended reality (XR) is an umbrella term that covers all immersive technologies: virtual reality (VR), augmented reality (AR), and mixed reality (MR). It spans the entire spectrum from fully virtual environments to simple overlays of digital information on the real world.

Question 3

What is a standalone VR headset?

Accepted Answer

A standalone VR headset operates without being tethered to a PC or console. It has its own processor, tracking sensors, and battery built in. Popular models include Meta Quest 3, Pico 4, and Apple Vision Pro. They offer great freedom of movement and are ideal for professional deployments (training, events).

Question 4

What is 6DoF tracking in virtual reality?

Accepted Answer

6DoF (six degrees of freedom) tracking captures both the rotation and position of the head in space (up/down, left/right, forward/backward). Unlike 3DoF which only detects rotation, 6DoF allows you to physically move within the virtual environment, providing a much more natural sense of immersion.

Question 5

What is spatial storytelling?

Accepted Answer

Spatial storytelling (or immersive storytelling) is the art of telling stories in three-dimensional space. Unlike traditional storytelling (linear, framed by a screen), it leverages the full 360° environment to guide the viewer's gaze and emotions. It applies to virtual tours, immersive training, cultural experiences, and VR/360° marketing.
