While this wasn’t a true VR test, because well…I don’t have a VR HMD sadly… I was able to simulate it pretty well using my Perception Neuron 32 Kit MoCap system, as well as Weibo’s excellent PN Plugin for UE4 as well as attaching a camera to my actor’s head.
Imagine all the possibilities in gaming if we had full control of ours bodies?! Obviously there are hand solutions available already, and your HMD would take care of the head movement. But what about if you want to elbow someone? Or Knee them? Or Kick them?
