Jason Jerald of NextGen Interactions has been involved with creating computer graphics and next-generation 3D computer interfaces for 20 years. His virtual reality consulting client list ranges from Oculus VR, Valve and Sixense Entertainment to NASA Ames Research Center, Battelle Pacific Northwest National Laboratories, Naval Research Laboratories, HRL Laboratories, DARPA & NIH.


We talk about some of his research and thoughts on VR latency, simulator sickness, presence and VR input devices & 3D user interface constructs. We also cover highlights from the IEEE VR, 3DUI, SIGGRAPH & Neurogaming conferences.
