However, the collaboration dynamic and its effectiveness may vary depending on the individuals involved. Particularly in scenarios where two individuals remotely control a robotic avatar without the possibility of direct communication, understanding each other\u2019s characteristics can result in enhanced performance. To achieve this, it is essential to ascertain if individuals can discern their partner\u2019s characteristics within the merged embodiment. This paper investigates the accuracy with which participants can distinguish between two different collaborating partners (one attempting to lead and one attempting to follow) when sharing control of a robot arm during a block pick-and-place task. The results suggested that participants who changed their roles according to the different roles of the two partners achieved the highest discrimination rates. Furthermore, participants changed their movements through the trials, adapting their actions to their preferred approach. This research provides insights into the factors determining individuals\u2019 ability to understand partner characteristics during control of collaborative avatars.<\/jats:p>","DOI":"10.1145\/3698237","type":"journal-article","created":{"date-parts":[[2024,10,1]],"date-time":"2024-10-01T14:58:51Z","timestamp":1727794731000},"page":"1-16","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["\u201cTogether with Who?\u201d Recognizing Partners during Collaborative Avatar Manipulation"],"prefix":"10.1145","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-0335-8492","authenticated-orcid":false,"given":"Kenta","family":"Hashiura","sequence":"first","affiliation":[{"name":"Keio University, Yokohama, Japan and The University of Tokyo, Bunkyo-ku, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3346-718X","authenticated-orcid":false,"given":"Takayoshi","family":"Hagiwara","sequence":"additional","affiliation":[{"name":"Keio University, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9036-3566","authenticated-orcid":false,"given":"Giulia","family":"Barbareschi","sequence":"additional","affiliation":[{"name":"Keio University, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8738-8540","authenticated-orcid":false,"given":"Sohei","family":"Wakisaka","sequence":"additional","affiliation":[{"name":"Keio University, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6303-5791","authenticated-orcid":false,"given":"Kouta","family":"Minamizawa","sequence":"additional","affiliation":[{"name":"Keio University, Yokohama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,11,15]]},"reference":[{"issue":"5","key":"e_1_3_1_2_1","doi-asserted-by":"crossref","first-page":"625","DOI":"10.1068\/p7008","article-title":"Me, myself, and I: different recognition rates for three photo-IDs of the same person","volume":"40","author":"Bindemann Markus","year":"2011","unstructured":"Markus Bindemann and Adam Sandford. 2011.
