| The Valve publications page has a few slides and documents relating to Valve presentations regarding VR: http://www.valvesoftware.com/company/publications.html One of my favorite tidbits comes in the presentation, "Lessons learned porting Team Fortress 2 to Virtual Reality", on preventing VR motion sickness: http://media.steampowered.com/apps/valve/2013/Team_Fortress_... > Don’t change the user’s horizon line, ever. You can see here how the camera follows the motion and rotation of the character’s head and so it rolls. Your actual head isn’t going to roll when you get killed by an Eyelander, so the mismatch will make you sick. Here's the presentation's video, bookmarked at the aforementioned insight: https://youtu.be/Gpr0FE2ATaY?t=19m36s For those of you non-TF2 players, the "Eyelander" is the name of a player-wieldable sword, and when it connects, the victim's head flies off and rolls around the ground. Apparently simulating that effect (changing the user's "horizon line") will make people very sick. |
