Despite these benefits, many individuals find it difficult to regularly attend in-person yoga classes due to factors like geographical location, physical and\/or mental health status, work schedules, or personal commitments. Currently, people try to overcome these barriers by using digital technologies, accessing live or recorded yoga lessons online and watching them on common screens. However, practicing yoga via traditional 2D screens can present challenges such as difficulty in perceiving and understanding the postures, as well as feeling less engaged, motivated, and socially connected with the instructor. This paper introduces an augmented reality (AR) solution that enables individuals to participate in yoga classes with a 3D instructor appearing in real-life size and depth within their living environments. The paper evaluates the application through a user study that compares it to the traditional 2D video approach. Results demonstrate significantly higher scores in perceived empathy, behavioral involvement, technology acceptance, and intrinsic motivation with the 3D instructor. Moreover, they suggest that combining the 3D instructor with additional AR elements that guide the user has a positive effect on user\u2019s self-competence. In discussing the findings, the paper outlines specific ways in which the application could be further improved.<\/jats:p>","DOI":"10.1007\/s10055-025-01231-z","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T15:29:00Z","timestamp":1757950140000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Yoga in augmented reality: comparison of a 3D experience versus traditional video of a lesson"],"prefix":"10.1007","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5975-4294","authenticated-orcid":false,"given":"Luca","family":"Chittaro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"1231_CR1","doi-asserted-by":"crossref","unstructured":"Anderson F, Grossman T, Matejka J, Fitzmaurice G (2013) YouMove: enhancing movement training with an augmented reality mirror.
