Yet the problem is that exploring large virtual environments is limited by the physical play area. To deal with this, many studies have considered redirection methodologies that imperceptibly manipulate the user\u2019s translational distance or direction in VR by constantly applying a gain while the user is walking. In this study, we propose RedirectedDoors, a novel redirection technique that manipulates the user\u2019s orientation during door-opening motions. A main characteristic of this technique is that the user\u2019s door-opening angle is coupled with the system\u2019s rotational manipulation of the entire VE at a specific ratio (i.e., gain) around the axis of the door hinge. Door opening is a routine daily action possibly compatible with many VR applications. From the results of user study, our technique showed a higher space efficiency of redirection.<\/p>\n<\/div>\n\n\n\n<div class=\"is-layout-flow wp-block-column\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"435\" src=\"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/redirecteddoors-1024x435.png\" alt=\"\" class=\"wp-image-3344\" srcset=\"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/redirecteddoors-1024x435.png 1024w, https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/redirecteddoors-300x127.png 300w, https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/redirecteddoors-768x326.png 768w, https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/redirecteddoors-1536x652.png 1536w, https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/redirecteddoors.png 1839w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"jetpack-video-wrapper\"><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe class='youtube-player' width='1170' height='659' src='https:\/\/www.youtube.com\/embed\/Iv-1pdqwahQ?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=ja&#038;autohide=2&#038;wmode=transparent' allowfullscreen='true' style='border:0;' sandbox='allow-scripts allow-same-origin allow-popups allow-presentation'><\/iframe><\/span><\/div>\n<\/div><\/figure>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h3>Publication<\/h3>\n\n\n\n<h4>International<\/h4>\n\n\n\n<ul><li>Yukai Hoshikawa, Kazuyuki Fujita, Kazuki Takashima, Morten Fjeld, and Yoshifumi Kitamura.
