Immersion + Interactivity = Tele-Presence. That is how the VR techies define Virtual Reality. For us regular folks, here is a simpler definition: Virtual reality is computer generated environment that allows the user to experience an alternate reality. This reality may or may not resemble ‘real life’. The headset uses two small lenses to feed the user’s eyes with three-dimensional images while headphones supply the accompanying soundtrack or noises.
The VR Engine
Virtual Reality headsets are powered by regular personal computers, since contemporary PCs are sophisticated enough to run software for Virtual Environments. Headsets consist of two monitors, one for each eye, and they combine images to create a stereoscopic effect. This creates the illusion of depth while exploring a virtual world.
The user is literally is immersed into a new world that is ‘near reality’ or virtual – so this is called immersion. Once in the user can interact with this new world. The combination of the immersion and the interactivity is what is called Telepresence.
Remember this formula? Immersion + Interactivity = Tele-Presence
VE designers determine the success of their design when the user becomes completely unaware of their real surroundings and solely focuses on their existence within the virtual environment.
So far most VE involve visual and audio simulation but engineers are working to incorporate the user’s sense of touch – user force feedback and touch interaction is called haptic systems.
- VE= Virtual Environments
- VRX= Virtual Reality Experiences
- Haptic Systems = User Force Feedback and Touch Interaction
How is it already changing our lives?
For perhaps the most obvious place of entry, virtual reality is edging into the Entertainment industry. Films are being filmed exclusively for VR headsets while live-streamed concerts are giving users a front-row experience from the comfort of their own home.
If you recall the computer monitor at the Home Depot that helps you select the right colour for the living room, it makes sense that the design industry has eagerly adopted VR tech. Pop on a headset, feed in a picture or two of the room that needs a renovation, you can build a new space with 3-D tools.
Collaborative experiences beyond traditional gaming are gaining momentum, you can tap in friends to help you build a 3-d painting -Google’s Tiltbrush. You can use apps and wand-like controllers to add further customisation to the 3-D experience.
Gaming has gotten infinitely cooler with VR as now game designers flip the switch on traditional designing, creating easter eggs and predicting where their player will actually turn or reach out and touch in the gaming dimension – the possibilities are only limited by their creativity
There is the logical extension of VR tech with Tourism and Exploration of places near and impossibly far – Google Cardboard and others promise a tour of the Planet Mars.
However, I think the potential of disrupting Meditation is infinitely more exciting! Psychologists in the United States have already starting using it with army vets to treat Post-traumatic Disorder. Researchers are using VR worlds to explore human behaviour in a safe space, suspended from reality.
Studies have shown VR sessions to work better than traditional painkillers – meaning it can be used in place of medicines to heal with distraction and engagement of the mind.
Video conferencing has become common-place, but VR technology means logging onto a Tele-presence robot that wheels around automatically in the workplace while you work from a remote location. It’s not all work, you can also log onto a chat room, not much different from The Sims, and chat or play in the guise of your game avatar.
Shopping in virtual reality is gonna be like never before,as you can try on a new pair of shoes or squeeze into a shirt before buying it online.
What Skills Are Required to Break into VR Tech Industry?
The virtual reality space has taken off and the demand for job candidates with VR knowledge has gone up by 37% since 2015! Since the tech is new, VR Startups and research companies are facing difficulty filling that demand. There are a large number of jobs available for those open to building virtual-reality apps, games, and experiences. If there is anything that screams CAREER OPPORTUNITY – this would be it.
There are two different types of VR content being created for VRX:
- 360 VR Video, and
- True-VR .
A career in 360 VR Video asks for experience in Film Production and VFX skill-set. The 360 video medium is a highly complex mixture of on-location production skills, sophisticated technical cameras and detailed post-production techniques. Once the experience is hot, technicians need to stitch scenes back into 360 spheres with tools like Kolor, or Nuke compositor. The final edits are made in Premiere, while any motion graphics tweaking is accomplished with After Effects or Fusion.
360 VR Video content can be used on Youtube 360, Facebook 360 as well as all apps and devices that play VR.
A contender for a job in the 360 VR would require portfolio that exhibits:
- Examples of grading and editing,
- VFX breakdowns of complex fixes ,
- Motion Tracking and embedded motion graphics,and
- A showreel with their best 360 video work, including samples of before and after post-production stitching.
Entering into a career in True-VR requires a strong pre-knowledge of game engine technology as well as a demonstrable game design skills-set. The workflow for True-VR is similar to traditional game development, from modelling and animating to the eventual rendering. Virtual Experiences created by True-VR technicians are geared for headsets such as Oculus Rift, Playstation VR, HTC Vive, and even the humble Samsung Gear VR.
Familiarity with the following programs will be beneficial for any True-VR hopeful:
- Animation and Modelling: Maya or 3ds Max
- Sculpting and Texturing: Mudbox, ZBrush, or Mari
- Final Rendering and Publication: Unity or UnReal Engine
Within True-VR there are two career paths:
Those looking to become VR Developers should have a showreel of VR experiences they have created for game engines, a downloadable link to the game or experience, sample code in C#, C+ or equivalent and further detail of the content they have created.
Those wanting to become 3D Artists should have a showreel that best exhibits their artistry in live games and experiences, wireframes and samples of their work in a game engine like Unity, UE4 or Marmoset.
- Strong Knowledge of Realtime Game Engine Tech + Arts Skills: Designing and Developing with 3D Modelling Software such as 3ds Max or Maya, texture or sculpting in Zbrush or Mari and Unity or UnReal Engine to pull the whole project together.
- SDKs (Software Development Kits) being used by VR developers, such as SDK 0.8 for Oculus,
- Head tracking, 3D calibration and side-by-side rendering, and
- Programming Experience with C or C ++ languages.
Leaning towards hardware? Skills from PC and Mobile Phone technology easily transfer over to immersive filming. You will need experience in Optics since visualisation is key for developing engaging Virtual Environments (VE).
Past Gaming – Where Else Can VR Be Found?
VR jobs are expected to show up in education, military and medical fields as tech can be used for trainings, simulations, safety modulations – as well as construction, engineering and architecture that can exploit 3D design to optimise models/estimates.
Venture into Computer Vision to understand the fundamentals of VR Tracking and camera-based user interaction. Cognitive computer engineers are needed to help businesses create, test, and evaluate cognitive software designed for their computer network.
On The Horizon
Scientists are also exploring the possibility of developing biosensors for VR use. A biosensor can detect and interpret nerve and muscle activity. With a properly calibrated biosensor, a computer can interpret how a user is moving in physical space and translate that into the corresponding motions in virtual space. Biosensors may be attached directly to the skin of a user, or may be incorporated into gloves or bodysuits. One limitation to biosensor suits is that they must be custom made for each user or the sensors will not line up properly on the user’s body
Thinking Out Loud
Is this it, fellow humans? Is the pinnacle of human ingenuity and creativity limited to regurgitating real-life scenarios onto digital screens for rapid consumption? Are we fulfilling the prophecy predicted by the animated movie ‘Wall-E’?
Are we destined to become increasingly sedentary, floating about on hoverchairs, consuming packaged foods, viewing the world through strapped-on headsets and booking our flights to the nearest planet?
