The technology provides many benefits given its highly immersive experience. Yet the drawbacks are that it requires large physical spaces. It can also lack the haptic feedback when touching objects. We have developed a new system to overcome this problem: RedirectedDoors+. The system, which built upon an existing visuo-haptic door-opening redirection technique, allows participants to subtly manipulate the walking direction while opening doors in VR, guiding them away from real walls. At the same time, it reproduces the realistic haptics of touching a doorknob, enhancing the quality of the experience. To provide users with that experience, RedirectedDoors+ employs a small number of &#8216;door robots.&#8217; The robots have a doorknob-shaped attachment and can move in any direction, giving immediate touch feedback when the user interacts with the doorknob. In addition, the virtual environment rotates in sync with the door movement, ensuring the user stays within the physical space limits. A simulation study conducted to evaluate the performance of the system demonstrated the physical space size could be significantly reduced in six different virtual environments. A validation study with 12 users walking with the system likewise demonstrated that this system works safely in real-world environments.<\/p>\n<\/div>\n\n\n\n<div class=\"is-layout-flow wp-block-column\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.icd.riec.tohoku.ac.jp\/wp-content\/uploads\/287_opening_new_doors_in_the_vr_world_t-1-e1743478288703.jpg\" alt=\"\" class=\"wp-image-5268\"\/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-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\/cdr1cvpe2_c?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 has-alpha-channel-opacity\"\/>\n\n\n\n<h3>Publication<\/h3>\n\n\n\n<h4>International<\/h4>\n\n\n\n<ul>\n<li>Yukai Hoshikawa, Kazuyuki Fujita, Kazuki Takashima, Morten Fjeld, Yoshifumi Kitamura, RedirectedDoors+: Door-Opening Redirection with Dynamic Haptics in Room-Scale VR, IEEE Transactions on Visualization and Computer Graphics, Vol. 30, Issue: 5, pp. 2276-2286, March 2024<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>RedirectedDoors+ Room-scale virtual reality (VR) is one where users explore a virtual environment by physicall [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":933,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"templates\/page-full-width.php","meta":[],"_links":{"self":[{"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/4133"}],"collection":[{"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=4133"}],"version-history":[{"count":1,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/4133\/revisions"}],"predecessor-version":[{"id":4143,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/4133\/revisions\/4143"}],"up":[{"embeddable":true,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/933"}],"wp:attachment":[{"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=4133"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
