VirtualSpace - Overloading Physical Space with Multiple Virtual Reality Users

どんなもの？

複数人を同じ物理空間につめこんでvrやらせつつ、ぶつからないようにうまく誘導することで空間シェア

先行研究と比べてどこがすごい？

this requires less space than the redirected walking technique

suggesting new usecase of visual guidance by incentives

技術や手法のキモはどこ？

各人が使えるスペースをtileとして区切って、うまく誘導

その上でtileを移動させる

それぞれのアプリ同士がうまく譲ったり奪ったりできる仕組み

どうやって有効だと検証した？

議論はある？

次に読むべき論文は？

what you like about it (explain why)

Virtual RAMという一見関係がないcomputer scienceの分野の仕組みを、空間/人間との類似を見出して転用していること。単なるアナロジーではなく、アルゴリズムまで転用できているのがすごい。

what you don't like about it (explain why),

what you think should have been done differently (explain why)

they should have tried the condition of "VirtualSpace without maneuvers" and "pre-allocated tiles with maneuvers"

current two conditions have two variables - pre-allocated divided space vs virtualspace and static vs maneurvers.

what you think should be done next (explain why).

we can apply this redirection technique for other usecases such as avoiding collisions with furnitures or other people not using VR. we can even try to let users walk in the city with VR HMD, by guiding users to walk the pedestrian pathway and follow the pedestrian crosswalk signals.
