Brains and VR - Why Should I Care?Virtual Reality is the most “Human” technology to date!Virtual Reality is about tricking your brain. We must first know the limits of our Perception, to be able to fool it and to augment it.

Motion SicknessTheories
Sensory conflictEvolutionary / Poison
Postural Instability Theory (Riccio and Stoffregen 1991)
Rest Frame Hypothesis (Prothero and Parker 2003)
Eye Movement Theory
@azadux
Motion SicknessHow to “fix” motion sickness? Smart Design!
Don’ts
No roller coasters
No strafing
No accelerated movements
Do’s
Add reference objects (cockpit style)
Notched rotation
Avoid up and down jumping (unless the person themselves jump)

Foveated Rendering Human 1.0 Eye Spec
Shutter, Aperture, lens, and an image sensor in the back called Retina
10 mm focal length lens
Variable f-number 3.2 to 8.3
576 megapixel!
7 megapixels actually matter.@azad

VR is a tool!
@azadux
Cognitive Research IssuesLengthy process
Ideas can run out of steamExpensive
Many ideas don’t get testedData collection issues
Tools, participants, and researchers vary@azad

VR as a Research ToolSuper-fast Prototyping
Test ideas quickly with Pilot experiments Everything is being tracked
Gaze, head angle, hands, walking location, emotion
@azadux
Research gets published and lost in Journals
But...
