Our work introduces \u201ciBreath\u201d, a novel system to detect breathing gestures similar to clicks using bio-impedance. We evaluated iBreath\u2019s accuracy and user experience using two lab studies (n=34). Our results show high detection accuracy (F1-scores &gt; 95.2%). Furthermore, the users found the gestures easy to use and comfortable. Thus, we developed eight practical guidelines for the future development of breathing gestures. For example, designers can train users on new gestures within just 50 seconds (five trials), and achieve robust performance with both user-dependent and user-independent models trained on data from 21 participants, each yielding accuracies above 90%. Users preferred single clicks and disliked triple clicks. The median gesture duration is 3.5-5.3 seconds. Our work provides solid ground for researchers to experiment with creating breathing gestures and interactions.<\/jats:p>","DOI":"10.1145\/3743710","type":"journal-article","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T14:28:48Z","timestamp":1757428128000},"page":"1-37","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["iBreath: Usage of Breathing Gestures as Means of Interactions MHCI016"],"prefix":"10.1145","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0527-1208","authenticated-orcid":false,"given":"Mengxi","family":"Liu","sequence":"first","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2643-4504","authenticated-orcid":false,"given":"Daniel","family":"Gei\u00dfler","sequence":"additional","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2123-828X","authenticated-orcid":false,"given":"Deepika","family":"Gurung","sequence":"additional","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9855-1040","authenticated-orcid":false,"given":"Hymalai","family":"Bello","sequence":"additional","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8976-5960","authenticated-orcid":false,"given":"Bo","family":"Zhou","sequence":"additional","affiliation":[{"name":"Embedded Intelligence","place":["Kaiserslautern, Germany"]},{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]},{"name":"University of Kaiserslautern-Landau (RPTU)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6760-5539","authenticated-orcid":false,"given":"Sizhen","family":"Bian","sequence":"additional","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0320-6656","authenticated-orcid":false,"given":"Paul","family":"Lukowicz","sequence":"additional","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]},{"name":"University of Kaiserslautern-Landau (RPTU)","place":["Kaiserslautern, Germany"]}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1419-7425","authenticated-orcid":false,"given":"Passant","family":"Elagroudy","sequence":"additional","affiliation":[{"name":"German Research Center for Artificial Intelligence (DFKI)","place":["Kaiserslautern, Germany"]}]}],"member":"320","published-online":{"date-parts":[[2025,9,9]]},"reference":[{"key":"e_1_3_4_2_2","unstructured":"2017.
