What’s different between virtual and augmented reality?
Which reality do you prefer? That may be an increasingly common entertainment choice in the next year or two as virtual-reality headsets such as Sony’s Project Morpheus and Facebook’s Oculus Rift go on sale and as companies such as Microsoft push augmented or “Mixed”-reality technology with what it’s calling “HoloLens.”
But what’s the difference between these technologies? There’s a lot of crossover, but generally speaking, virtual-reality is more fully immersive. Imagine “Tron,” in which the human characters are inside a virtual world. A headset like Oculus Rift or Samsung’s GearVR could simulate that in a video game, or in films.
Augmented reality or mixed reality is more like a virtual layer on the real world or real-world objects (say a basketball) interacting with virtual settings. A cell phone app that appears to make a virtual, 3-D-animated pet show up on your coffee table would be one example of augmented reality.
