New technologies are coming in virtual reality headsets, and terms are getting bandied about like everybody already knows what they are. Here are most of the terms you’re hearing, and what they mean
Rumors suggest that Apple VR will have an 4K display for each eye, a powerful M-series processor, and extensive user tracking features. It could cost up to $2,000 in its first iteration.
The following terms apply to the headset market in general and have been used, at least in part, to describe upcoming features for Apple’s headset. These terms are lightly technical, but aren’t self-explanatory at first glance.
All the terms are listed alphabetically. We’ll be adding new terms as they are introduced.
What is augmented reality?
Augmented reality, or AR, refers to a software overlay that is independent of the real world. Consumers got their first taste of AR products through things like the Nintendo 3DS, PS Vita, and Google Glass.
Augmented Reality places digital objects as an overlay of the real world
Apple has pushed hard for augmented reality to become an integral part of its operating systems. However, it hasn’t moved beyond being an interesting party trick, for the most part.
Users can use augmented reality on their iPhone or iPad today for various gaming experiences or art installations. Apple has even added an AR direction mode to Apple Maps, though it is limited and requires the user to hold their iPhone up in the air to view the information.
Augmented reality differs from mixed reality, which uses information from the real world to produce 3D overlays. AR is more passive, meaning it will look more like a heads-up display, not a fully-rendered video game.
For example, “Pokemon Go” will use a device’s LiDAR to find a flat surface and place a Pokemon there to interact with. It doesn’t change what kind of environment is viewed through the display — the software just adds the creature irrespective of what is surrounding it.
It is expected that Apple will use augmented reality in a limited fashion for its first virtual reality headset. It may allow for some real-world image passthrough to help users set up rather than offer full AR experiences.
What is eye-tracking?
Eye tracking uses the exact movement of the user’s eyes to animate an avatar or control movements. This is different from foveated rendering or field of view.
For example, a VR headset with eye tracking can be used to animate an avatar’s eyes within a virtual meeting room. It enables a more realistic depiction of the user’s emotion or viewing direction.
This is also useful for judging when a user is trying to see outside their field of view without turning their head. The VR experience can adjust to show that region or navigate a menu with minimal user interaction.
What is field of view?
Field of view is the area visible in front of the user’s eyes due to the available screen real estate. VR headsets generally have a set field of view that is …….
