The document discusses various applications of virtual reality (VR), highlighting health issues like cybersickness and solutions for improving VR performance. Key technical requirements for VR systems include high resolution, low latency, and accurate tracking. It also briefly mentions VR parachuting and specific challenges related to video game performance.
Virtual Reality programming and designing issues
- 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 TRICKS http://www.purdue.edu/newsroom/releases/2015/Q1/virtual-nose-may-reduce-simulator-sickness-in-video-games.html
