Mini-glossary: Virtual reality terms you should know

Mini-glossary: Virtual reality terms you should know | Moodle and Web 2.0 | Scoop.it
Virtual reality is the buzzy "it" technology these days, and by the looks of things, it's going to be that way for a while. If you're still fuzzy on what it all means, take a few minutes to dig yourself out of the jargon pile by getting familiar with some of the keywords you're likely to run into, as well as a quick hit on the big products on the market, and what will be hitting the market this year and next.

Head mounted display or HMD
This is probably one of the most common terms you're bound to run into in hearing or reading about virtual reality, especially because for the most part, HMDs are the current form of hardware delivering VR experiences to users. It's typically goggles or a helmet of some type, the kind you strap to your face or put on your head. That's where you're viewing the VR experience. Some have sensors for head tracking, some don't.

Head tracking
Speaking of head tracking, this term refers to the sensors that keep up with the movement of the user's head and move the images being displayed so that they match the position of the head. In short, if you're wearing an Oculus Rift, for example, head tracking is what lets you look to the left, right, up, or down, and see the world that's been built in those directions.

Eye tracking
Eyetracking is similar to headtracking, but matches leans on where the user's eyes are looking. So for example, there's an HMD (you learned this earlier!) called FOVE that integrates eye tracking into their headset. In their demo, the user can aim a weapon (it looks like a laser) by looking in a different direction. Alternatively, a game like Rocket Toss relies on the user aiming with his or her head to determine the direction of rings.

Field of view (FOV)
Field of view is the angle of degrees in a visual field. Having a higher field of view is important because it contributes to the user having a feeling of immersion in a VR experience. The viewing angle for a healthy human eye is about 200 degrees. So, the bigger that angle is, the more immersive it feels.

Latency
If you've ever tried a VR experience and noticed that when you turn your head, the visuals don't quite keep up, that's latency. It's unpleasant, because that's not something that happens in the real world. That lag is an oft-cited complaint about VR experiences that aren't up to par for a variety of reasons.

Simulator sickness
Simulator sickness is a conflict of sorts between what your brain and body think they're doing. Your eyes say, "We're moving!" And your brain says "Nope! Let's get nauseated!" Science Magazine suggests that this disparity is interpreted as a toxin, and the human body does what it can to get that toxin out, ergo, vomiting. As much as people look at virtual reality and want to do things like fly or jump, for many folks, it's the beginning of a bad idea. But, as everyone has different thresholds, not everyone gets sick, or as sick as someone else might. This is one of the big challenges for developers — figuring out how to move people without making them ill.

Judder
Outside of virtual reality, judder is a significant shaking. But as for VR, Oculus' CTO Michael Abrash defined it like this in a blog post from 2013 when he was still at Valve Software: "a combination of smearing and strobing that's especially pronounced on VR/AR HMDs."

Refresh rate
If you're looking at a television, or, in this case, a virtual reality experience, you're looking at a series of images. The refresh rate is how fast those images get updated. Higher refresh rates cut down on lag, and cutting down on lag means there's less of a chance of getting sick. It also means more responsive experiences. You definitely want to be north of 60 frames per second.

Haptics
Here's another word that's not exclusive to virtual reality, but still gets play. It's tactile feedback. In VR, that would mean users feeling like they're touching something that's not really there. In June, Oculus unveiled its Oculus Touch controllers — the Half Moon prototype, and one of the features was haptics.

Presence
If virtual reality strives to takes users and immerse them in new environments, presence is what's achieved when that happens. Plain and simple, users feel like they're there, wherever "there" is.

Metaverse
There's not exactly a definitive definition. It's a bit prickly. Broadly, it's a bit of a philosophical underpinning of virtual reality; Forbes defines it as a "collective virtual reality," but there's plenty of debate about what that applies to and really, what exactly that is. A suggestion: check out Snowcrash by Neal Stephenson. It's a 1992 sci-fi that envisions a metaverse.

A brief rundown of the big players
Oculus Rift

Oculus has released two developer kits, and has a prototype called Crescent Bay they've been demoing in the past year or so. Their consumer version is slated to hit the market in Q1 of 2016. Facebook bought the company in 2014 for $2 billion.

Samsung Gear VR Innovator Edition

The Gear is powered by Oculus, but differs in that its display is the screen of the Samsung Galaxy S6 and S6 Edge. There's been one previous iteration. The Samsung platform features a variety of games, game demos, 360 videos, 360 videos, and other VR experiences both computer-generated and cinematic.

Sony's Project Morpheus

Project Morpheus will be compatible with PlayStation 4. There's no release date, but it's expected sometime in the first half of 2016. In pictures, you typically see people wearing the headset and holding two wands as input devices.

HTC Vive

The buzz is that the Vive might be the Rift's best competition. It's a partnership between hardware maker HTC, and videogame maker Valve, powered by the SteamVR platform. It has two wireless hand controllers, and two sensors to be placed in the room. It's supposed to be released toward the end of 2015.

Google Cardboard

Google introduced its cardboard holder in 2014 at its I/O conference. A user's cell phone fits into the front and the user hold the holder up to his or her face. It doesn't have any sensors, which makes some VR purists dismiss it as too low quality, as it relies on the phone's accelerometer. On the other hand, the fact that it's cheap and the newer version accommodates phones with screens up to 6 inches, can potentially put VR in the hands of a very wide audience. Users can find apps on the Google Play store. There's also the Cardboard app.

How “Playing With Technology” Led Me to the Job of My Dreams

How “Playing With Technology” Led Me to the Job of My Dreams | Moodle and Web 2.0 | Scoop.it

"What an awesome TED Talk! The description is: “What happens when you’re looking for a job in the middle of a recession? Stop doing what people tell you to do. Charlie Hoehn talks about making up your own rules and how he started only working on things he wanted to pursue and how it changed his life.” I completely agree with Charlie’s premise that we don’t find the work we love with a college degree. We pigeon-hole ourselves into a niche where we have to search on Monster.com for a job, and then despise the search results. Or we write on our resumes “proficient in Microsoft Office” and then wonder why no one cares."
