Analysis of some problems that could arise when developing an application for VR with a current game engine (e.g. Unity3D)

1. VIRTUAL REALITY

2. • Some interesting uses nowadays
• VR correlated health issues and how to avoid/reduce them
• Brief presentation of VR Parachuting
• Problems encountered w.r.t.“canonical” videogames
• Solutions adopted for performance improvement
KEY POINTS

3. ARCHITECTURE

4. SURGERY

5. Headache
Stomach awareness
Nausea
Sense of vomiting
Disorientation
CYBERSICKNESS

6. THE MAIN CAUSE
• 3 semicircular canals
filled with liquid
• Head rotations
around 3 axes move
liquid inside them
• Liquid pushes on
cupula, which
translates mechanical
movements into
electric signals

7. • Adequate resolution (> 1080p)
• Low pixel persistence (< 3 ms)
• High graphics refresh rate (> 60 Hz, 95 Hz adequate)
• Tracking accuracy (< 1 mm translation, 0.25° orientation)
• Low latency (< 25 ms)
REQUIREMENTS
• Wide field of view (> 80°)

8. Static objects into view
• Virtual cockpit
• Virtual nose
