But really, What is VR?

The definition of Virtual Reality can be a bit slippery and can vary depending on who you ask. But all subjectivity aside, virtual reality is a computer-generated artificial environment. When done properly, VR transports users to an alternate simulated environment created to stimulate a user’s sight, smell, touch, hearing and vision to make them belief the experience is real. Achieving this goal hinges on whether the specific VR technology can make a user feel that they are “in” the experience. Of course, not all senses must be tapped to create such an allusion, but the more senses stimulated the better for total immersion. Here is where the VR community is at with stimulating the various senses.

Vision

Head Mounted Displays, or HMD’s, like the PlayStation VR and Oculus Rift are becoming the clear choice for VR end users as a method for delivering high class graphics at historically rock-bottom prices. HMD’s are display devices that are worn on one’s head or as part of a helmet. The Oculus company was a pioneer in compiling the technology at reasonable rates around 2015. Prior to the Oculus Rift, most consumer HMD’s had a diagonal field of view of about 30 to 40 degrees, and you were only able to see a small image way off in the VR distance. But the oculus Rift debuted a 110-degree diagonal field of vision that made users feel less like they were staring at a VR screen and more like they were “in” the experience. What’s more, the device originally sold for $600 dollar’s making it accessible to programmers and gamer’s alike.

Once HMD hardware became available the applications for the device have expanded rapidly including innovations in gaming, aviation, engineering, and medicine. Companies like XR are using HMD tech to deliver workspace solutions to a variety of industries.

Audio

When it comes to VR immersion, perhaps the most important sensory input is sound as people react first to auditory cues than visual ones. Many VR content creators use binaural recording to create a 3-D sound sensation. Two microphones are set up 7 inches apart often in a ‘dummy head recording” where each “ear” is fitted with a microphone. This type of recording and play back go back to 1881 but did not gain favor with the public until the 1980’s. Spatial audio is now coming into its own with the ability to “localize” a sound, where if you had your eyes closed you could imagine certain sounds emanating from a particular direction and distance.

Touch

Tactile inputs are still being developed and incorporated into the VR landscape. Tactile input can include light touch, firm touch, and the perception of different textures including dry to wet and messy. Such inputs as omni-directional treadmills simulate walking or running through content rather than passively experiencing from a chair or couch. Tactile input wearables such as the ‘teslasuit’ are being integrating Electro Muscular Stimulation, or EMS, into a wireless suit. The suit is intended to mimic sensations ranging from a cool breeze to the impact of a bullet. Such technology has not yet gone mainstream, but when it does, it is sure to be a game changer.

Other tactile inputs have been developed and implemented in VR for over 20 years. Haptics or touch feedback has progressed from vibrating rumble motors to ultrasonic feedback. Children of the 90’s will remember one of the first widespread applications of haptics as the “rumble pack” attachment to the Nintendo 64 game controller. When one pulled the trigger on the controller a spinning weight motor would make the controller vibrate simulating action. Modern Haptics can be found in newer smart-phones.

Taste & Smell

The taste and smell sensations have not developed in VR at the same rate as the other senses. This remains a mystery to those that see these sense’s as the holy grail of the VR experience. Recent research by the University of Ottawa has found that adding smell to a VR environment “increases the sense of presence”. Several theme park attractions have used perfumery to trick the minds and noses of audiences. When the viewer approaches a dumpster, an unpleasant odor would fill the room. Or conversely as the attraction content approached an orange grove a pleasant citrus odor would be piped in. Perceptions of smell can also alter what a VR user is tasting according to the Tokyo University’s Cyber Interface Lab who is undergoing a “Meta-Cookie” project.

Tomorrow’s VR

Tomorrow’s VR will incorporate all the senses into an experience that rivals real life and beyond. Leaders of the VR sector like Oculus founder, Palmer Luckey, and Tsunami XR CEO, Alex Hern, are at the forefront of this breakthrough. Some analyst are predicting the VR market to rise to $209.2 billion in 2022, which will surely be attributed to heightened sensory inputs.

  1. Head Mounted Displays, or HMD’s, like the PlayStation VR and Oculus Rift are becoming the clear choice for VR end users as a method for delivering high class graphics at historically rock-bottom prices. HMD’s are display devices that are worn on one’s head or as part of a helmet.

  2. I think virtual reality is an interesting concept with a promising future. It will certainly make playing video games a lot more exciting.

  3. I actually used a VR headset for the very first time the other day! It was just a video, not a game, but it was a neat experience. I didn’t expect it to be so much like watching a 3D movie (with without the red/blue lenses of course) and it was still quite immersive without headphones. I’m sure wearing headphones would have made the experience much different and I can’t imagine how it would have been with taste or smell too.

  4. Virtual reality is good. In this article, they gave nice information about Virtual reality. Very easy to understand.
    Informative.

  5. Great to see so much compitition in the market of video gaming and VR technology. I own the HTC Vive and as much as i love it, Im really excited to see what new technology and innovations these big and new companies can offer to us gamers. Thanks for the great informative article.

  6. I gotta agree, taste and smell would indeed be the Holy Grail of Virtual Reality. I’ve not gotten to experience the new VR yet but I’m really excited about it. I figure by the time I can afford it, it’s going to be super neat! Haptics are also getting better and cooler. Welcome to the future!

  7. I just recently purchased VR goggles so my son could use them with his phone. He has absolutely loved being able to experience watching videos with virtual reality. They have to be real careful when wearing though. I have seen him run into a wall because he would get so wrapped up in them.

  8. I’ve got to say, I can’t stop considering me buying a VR headset, even when I know that the technology is going to be advanced so much further in the next few years, as mentioned in the article. Even though current VR headsets only immerse in the sight and sound senses, it still seems like you are completely in the world played out in your head. Am very excited to see this develop in the future.
