0 likes355 views
This document discusses solutions for virtual reality motion sickness from Preview Labs, a company that focuses on rapid prototyping for games and interactive software. It outlines various solutions that have been implemented or studied, such as showing a virtual nose, limiting field of view, subtle vignetting, avoiding rotation and tilting, indicating collisions, and ensuring a gradual build-up of VR experiences. It also describes challenges encountered in prototyping a forklift simulator and journey game. Links are provided for further information on different solutions and studies.

VRCheck 2017 - Preview Labs
- 1. Rapid prototyping for games & interactive software Development in Belgium, and of鍖ce in New Haven, CT Prototyped over 100 projects since 2010 The only company worldwide with this focus @PreviewLabs
- 2. PC Mobile Educational Serious VR AR Support for any platform or genre! We like prototyping so much, we made it our business model @PreviewLabs
- 9. Di鍖erent causes Motion felt but not seen Motion seen but not felt Felt motion and seen motion do not correspond Virtual reality sickness
- 10. Solu:ons are already present in VR products Latency Advanced tracking sensors Frame rate
- 11. Experimental solu:ons Purdue University study: showing a nose in VR
- 12. Experimental solu:ons Reliefband: delivers nerve-modulating electrical pulses to the area of the brain controlling nausea
- 13. Other solu:ons Hyper-Dash: VR Movement based on your center of gravity. If you tilt with your body, youll move (Fantom Fathom LLC)
- 14. Other solu:ons Electrodes stimulating your inner ear. Technology 鍖rst used for military 鍖ight sims (Mayo Clinic)
- 18. Case: ForkliE Operator Goals: more realistic, less motion sickness It made motion sickness even worse when parameters werent tweaked well It made motion sickness only marginally better when parameters were perfectly adjusted Result: Seems not really worth the time and effort
- 20. Case: ForkliE Operator Gradual instead of abrupt movements would work, right? Yes, but what if you bump into something? Abrupt stops are realistic behavior! Gradual movements would even increase motion sickness in this case. Solution: indicate that the user is almost going to bump into something. Brace yourself! Other solution: We added rear view mirrors.
- 22. Case: ForkliE Operator Best solution: no locomotion at all? Teleportation is often used in VR titles But not really an option if youre making a vehicle simulator
- 24. Journey for Elysium Prototype At the very least, avoid rotation and tilting at all costs. Its much worse than just moving!
- 25. Other solu:ons Limiting in-game view by a static surrounding environment (e.g. Cockpit)
- 26. Other solu:ons Subtly vignetting the players 鍖eld of view if he/she is moving in VR (Columbia Engineering)
- 27. Other solu:ons Do not show body parts if they are not tracked
- 28. Other solu:ons People will start compensating after repeated experiences in VR. Ensure a slow build-up of VR experiences.
