Questions Asked in Immersive Storytelling and Virtual Reality Interview
Q 1. Explain the difference between VR, AR, and MR.
The terms VR, AR, and MR represent different levels of immersion in digital environments. Think of it like a spectrum of reality augmentation.
- Virtual Reality (VR): Completely replaces your real-world surroundings with a simulated environment. You’re fully immersed, typically wearing a headset that blocks out your physical view. Imagine being transported to another planet – that’s VR.
- Augmented Reality (AR): Overlays digital information onto the real world. You see your real-world surroundings, but with added elements. Think Pokémon Go – the Pokémon appear on your phone screen, superimposed over your view of the street.
- Mixed Reality (MR): Blends the real and virtual worlds seamlessly, allowing you to interact with both digital and physical objects. Imagine a virtual object in your living room that you can walk around and even touch (through haptic feedback). MR requires more advanced technology than AR and provides a greater sense of presence.
The key differences lie in the level of immersion and interaction with the real world. VR is fully immersive, AR overlays information, and MR blends the two seamlessly.
Q 2. Describe your experience with a specific VR/AR development engine (e.g., Unity, Unreal Engine).
