  • VIRTUAL REALITY

  • 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

  • ARCHITECTURE

  • SURGERY

  • Headache

    Stomach awareness

    Nausea

    Sense of vomiting

    Disorientation

    CYBERSICKNESS

  • 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

  • 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)

  • Static objects into view Virtual cockpit Virtual nose

    TRICKS
