Virtual Reality programming and designing issues

  1. 1. VIRTUAL REALITY
  2. 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. 3. ARCHITECTURE
  4. 4. SURGERY
  5. 5. Headache Stomach awareness Nausea Sense of vomiting Disorientation CYBERSICKNESS
  6. 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. 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. 8. Static objects into view • Virtual cockpit • Virtual nose TRICKS http://www.purdue.edu/newsroom/releases/2015/Q1/virtual-nose-may-reduce-simulator-sickness-in-video-games.html
