The system controls the inclination angle and motion speed with the aim of achieving manipulative but unobtrusive posture guidance.<\/p>\n\n\n\n<p>To demonstrate its potential, we first built a prototype of TiltChair with a seat that could be tilted by pneumatic control. We then investigated the effects of the seat\u2019s inclination angle and motions on task performance and overall sitting experience through two experiments. The results show that the inclination angle mainly affects the difficulty of maintaining one\u2019s posture, while the motion speed affected the conspicuousness and subjective acceptability of the motion. However, these seating conditions did not affect objective task performance. Based on these results, we propose a design space for facilitating effective seat-inclination behavior using the three dimensions of angle, speed, and continuity. Furthermore, we discuss promising applications according to the design space.<\/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\" src=\"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-content\/uploads\/sites\/3\/thumb\uff08\u5c0f\u3055\u3044\uff09-2.png\" alt=\"\" class=\"wp-image-1271\"\/><\/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\/9XvbA-nKTBc?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>Publications<\/h3>\n\n\n\n<h4>International<\/h4>\n\n\n\n<ul id=\"block-5bd43ccb-2bf1-4a83-bf8e-32b75803abfc\"><li>Kazuyuki Fujita, Aoi Suzuki, Kazuki Takashima, Kaori Ikematsu, Yoshifumi Kitamura,<br><span class=\"has-inline-color has-black-color\"><a href=\"https:\/\/doi.org\/10.1145\/3411764.3445151\">TiltChair: Manipulative Posture Guidance by Actively Inclining the Seat of an Office Chair<\/a>,<\/span><br>Proc. of the 2021 CHI Conference on Human Factors in Computing Systems (CHI &#8217;21), May. 2021.<\/li><\/ul>\n\n\n\n<h4>Domestic<\/h4>\n\n\n\n<ul><li>\u9234\u6728 \u84bc\u751f, \u85e4\u7530 \u548c\u4e4b, \u9ad8\u5d8b \u548c\u6bc5, \u6c60\u677e \u9999, \u5317\u6751 \u559c\u6587,<br><a href=\"https:\/\/www.interaction-ipsj.org\/proceedings\/2021\/data\/pdf\/1A07.pdf\">TiltChair:\u5ea7\u9762\u306e\u524d\u50be\u306b\u3088\u308a\u59ff\u52e2\u8a98\u5c0e\u3059\u308b\u30aa\u30d5\u30a3\u30b9\u30c1\u30a7\u30a2<\/a>\uff0c<br>\u30a4\u30f3\u30bf\u30e9\u30af\u30b7\u30e7\u30f32021\u8ad6\u6587\u96c6\uff0cpp. 134-139\uff0c2021\u5e743\u6708\uff0e<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"<p>TiltChair We propose TiltChair, an actuated office chair that physically manipulates the user\u2019s posture by act [&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\/1274"}],"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=1274"}],"version-history":[{"count":8,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/1274\/revisions"}],"predecessor-version":[{"id":2032,"href":"https:\/\/www.icd.riec.tohoku.ac.jp\/en\/wp-json\/wp\/v2\/pages\/1274\/revisions\/2032"}],"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=1274"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
