For example, touching on the desk by the user should be reproduced by the avatar in the remote space to correctly convey the intended meaning. It is unlikely, however, that the two involved physical spaces are exactly the same in terms of the size of the room or the locations of the placed objects. Therefore, a naive mapping of the user's joint motion to the avatar will not create the semantically correct motion of the avatar in relation to the remote environment. Existing studies have addressed the problem of retargeting human motions to an avatar for telepresence applications. Few studies, however, have focused on retargeting continuous full\u2010body motions such as locomotion and object interaction motions in a unified manner. In this paper, we propose a novel motion adaptation method that allows to generate the full\u2010body motions of a human\u2010like avatar on\u2010the\u2010fly in the remote space. The proposed method handles locomotion and object interaction motions as well as smooth transitions between them according to given user actions under the condition of a bijective environment mapping between morphologically\u2010similar spaces. Our experiments show the effectiveness of the proposed method in generating plausible and semantically correct full\u2010body motions of an avatar in room\u2010scale space.<\/jats:p>","DOI":"10.1111\/cgf.14740","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T09:49:51Z","timestamp":1684835391000},"page":"13-24","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Online Avatar Motion Adaptation to Morphologically\u2010similar Spaces"],"prefix":"10.1111","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0832-6545","authenticated-orcid":false,"given":"Soojin","family":"Choi","sequence":"first","affiliation":[{"name":"Visual Media Lab, KAIST"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7090-146X","authenticated-orcid":false,"given":"Seokpyo","family":"Hong","sequence":"additional","affiliation":[{"name":"Samsung Advanced Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0714-4686","authenticated-orcid":false,"given":"Kyungmin","family":"Cho","sequence":"additional","affiliation":[{"name":"Anigma Technologies"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8355-7522","authenticated-orcid":false,"given":"Chaelin","family":"Kim","sequence":"additional","affiliation":[{"name":"Visual Media Lab, KAIST"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1925-3326","authenticated-orcid":false,"given":"Junyong","family":"Noh","sequence":"additional","affiliation":[{"name":"Visual Media Lab, KAIST"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,5,23]]},"reference":[{"key":"e_1_2_13_2_2","doi-asserted-by":"crossref","unstructured":"Al-AsqharR.
