In this study, we propose LoopBot, a novel technique to provide continuous haptic feedback from grounded objects using only a single user-following robot. Specifically, LoopBot is equipped with a loop-shaped haptic prop attached to an omnidirectional robot that scrolls to cancel out the robot\u2019s displacement, giving the user the haptic sensation that the prop is actually fixed in place, or \u201cgrounded.\u201d To prove the concept of LoopBot, we implement a prototype for the experience of walking while grasping handrails. A preliminary user test (\ud835\udc41 = 10) also shows that the subjective realism of the experience and the sense of the virtual handrails being grounded were significantly higher than when the prop was not scrolled.<\/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\" loading=\"lazy\" width=\"959\" height=\"348\" src=\"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/image-1.png\" alt=\"\" class=\"wp-image-4167\" srcset=\"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/image-1.png 959w, https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/image-1-300x109.png 300w, https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/image-1-768x279.png 768w\" sizes=\"(max-width: 959px) 100vw, 959px\" \/><\/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\/YhgQCpXWImA?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>Tetsushi Ikeda, Kazuyuki Fujita, Kumpei Ogawa, Kazuki Takashima, Yoshifumi Kitamura, LoopBot: Representing Continuous Haptics of Grounded Objects in Room-scale VR, Proceedings of the 37th Annual ACM Symposium on User Interface Software and Technology (UIST &#8217;24), Article No. 135, pp. 1-10, October 2024,&nbsp;<a href=\"https:\/\/dl.acm.org\/doi\/10.1145\/3654777.3676389\">10.1145\/3654777.3676389<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>In room-scale virtual reality, providing continuous haptic feedback from touching grounded objects, such as wa [&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\/4129"}],"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=4129"}],"version-history":[{"count":4,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/4129\/revisions"}],"predecessor-version":[{"id":4170,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/4129\/revisions\/4170"}],"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=4129"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
