Ofcourse, once you threw the ball too high, the virtual version would stop mid-air and before you knew it, you got smacked in the head with reality. The solution was cool, and very-very expensive. There was also some technology for untethered VR that actually worked, so we might see VR cabels dissapearing sooner than we might think.
Next we had a presentation by Aleksander Väljamäe, a local academic and researcher who has been heavily involved in VR related science since the beginning of the 2000s. The presentation gave a really brief introduction to his wealth of work already done in the VR space. This included auditory illusions, the sense of self-motion, out of body experiences etc. Currently Aleksander is setting up a new lab in Tallinn University to investigate brain-computer interactions through media. For anyone dealing with VR audio, this talk will surely give some interesting new insight.
