Here are the essential VR concepts where we give a brief explanation to help you along on your Virtual Reality journey.
When developing the VR experience, we are able to minimize the effects of simulator sickness by utilizing teleportation to move, software optimization to ensure high framerates as well as other best practices.
Depth of the 3D world in VR creates spatial awareness of the virtual world as your left and right eyes are seeing different images on the VR headset. You can now tell how far the virtual objects are from another object instinctively as this is exactly what happens in real life.
Scale of the 3D world in VR is often life size. You can see a blue whale in its full majestic size compared to a 10cm image or video on a screen.
Positional or 6DOF tracking allows a player to replicate their real life movement with the virtual movement. More advanced VR headsets like HTC Vive and Oculus Quest have this tracking type. These devices will allow the players to feel more immersed and allows more dynamic VR experiences.
Hand tracking makes use of sensors like the leap motion device or the inside-out tracking cameras on the VR headset itself to track your hand gestures to replicate in VR. It is often used for simple actions that does not need high accuracy.
Hand controllers are tracked to a high precision and represent your hands. In addition, there are buttons on it that allow you to perform different and precise actions when you press them. They also offer a tactile feedback when you press on them.
A basic spatialized sound setup will allow you to tell you where the sound comes from accurately, whether it is behind, to the left or right, from far away or just beside you. A more complicated spatialized sound setup will take into consideration the size, shape and material of the virtual environment when calculating how the sound travels and bounces off surfaces to reach your ears.
The simplest form that we always design for is to use vibrations on the hand controllers so that people know that they have touched or triggered something in the virtual world. Other ways of integrating haptics into VR is by using custom controllers or additional equipment like haptic vests.
Why use Virtual Reality for Business
VR is an amazing technology that brings immersion in ways not possible with a computer or smartphone. However it is not the solution to every problem. VR works for business when applications are able to achieve cost-savings, increased productivity, reduce risks and also achieve the impossible. Often these use cases need to be tested with a prototype to see if it is successful in enabling businesses.
