Our primary aim was to examine whether physical contact by hugging a <jats:italic>Hugvie<\/jats:italic> could reduce the stress of speaking with an unfamiliar person on the phone in individuals with ASD. We enrolled 24 individuals and requested them to carry out phone conversations either using only a mobile phone or using a mobile phone along with the <jats:italic>Hugvie<\/jats:italic>. All participants in both groups completed questionnaires designed to evaluate their self-confidence while talking on the phone, and also provided salivary cortisol samples four times each day. Our analysis revealed that the medium of communication was a significant factor, indicating that individuals with ASD who spoke with an unfamiliar person on the phone while hugging a <jats:italic>Hugvie<\/jats:italic> had stronger self-confidence and lower stress levels than those who did not use <jats:italic>Hugvie<\/jats:italic>. Hence, we recommend that huggable devices be used as adjunctive tools to support individuals with ASD during telephonic conversations with unfamiliar people.<\/jats:p>","DOI":"10.1371\/journal.pone.0254675","type":"journal-article","created":{"date-parts":[[2021,7,23]],"date-time":"2021-07-23T17:34:30Z","timestamp":1627061670000},"page":"e0254675","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["A huggable device can reduce the stress of calling an unfamiliar person on the phone for individuals with ASD"],"prefix":"10.1371","volume":"16","author":[{"given":"Hidenobu","family":"Sumioka","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2567-0276","authenticated-orcid":true,"given":"Hirokazu","family":"Kumazaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taro","family":"Muramatsu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichiro","family":"Yoshikawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Ishiguro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haruhiro","family":"Higashida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teruko","family":"Yuhi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaru","family":"Mimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,7,23]]},"reference":[{"key":"pone.0254675.ref001","doi-asserted-by":"crossref","first-page":"702","DOI":"10.1089\/cyber.2014.0098","article-title":"Face-to-face or not-to-face: a technology preference for communication","volume":"17","author":"NI Jaafar","year":"2014","journal-title":"Cyberpsychol Behav Soc Netw"},{"key":"pone.0254675.ref002","doi-asserted-by":"crossref","first-page":"344","DOI":"10.1016\/j.jaac.2017.01.007","article-title":"Are social and communication difficulties a risk factor for the development of social anxiety?","volume":"56","author":"H Pickard","year":"2017","journal-title":"J Am Acad Child Adolesc Psychiatry"},{"key":"pone.0254675.ref003","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1111\/j.1944-9720.1998.tb01333.x","article-title":"Listening comprehension anxiety: students\u2019 reported sources and solutions","volume":"31","author":"AJ Vogely","year":"1998","journal-title":"Foreign Lang Ann"},{"key":"pone.0254675.ref004","doi-asserted-by":"crossref","first-page":"246","DOI":"10.1016\/j.neubiorev.2008.10.004","article-title":"The science of interpersonal touch: an overview","volume":"34","author":"A Gallace","year":"2010","journal-title":"Neurosci Biobehav Rev"},{"key":"pone.0254675.ref005","doi-asserted-by":"crossref","first-page":"39718","DOI":"10.1038\/srep39718","article-title":"Eyeblink synchrony in multimodal human-android interaction","volume":"6","author":"K Tatsukawa","year":"2016","journal-title":"Sci Rep"},{"key":"pone.0254675.ref006","doi-asserted-by":"crossref","unstructured":"Chang A, O\u2019Modhrain S, Jacob R, Gunther E, Ishii H.
