While the potential of AR is well known, the perspectives and requirements of individuals with mental disabilities, who face both cognitive and psychological barriers at work, have yet to be addressed, particularly on Head-Mounted Displays (HMDs). To understand practical limitations of such a system, we conducted a mixed-methods user study with 29 participants, including individuals with mental disabilities, their colleagues, and support professionals. Participants used a commercially available system on an AR HMD to perform a machine setup task. Quantitative results revealed that participants with mental disabilities perceived the system as less usable than those without. Qualitative findings point towards actionable leverage points of improvement such as privacy-aware human support, motivating but lightweight gamification, user-controlled pacing with clear feedback, confidence-building interaction patterns, and clearer task intent of multimodal instructions.<\/jats:p>","DOI":"10.3390\/virtualworlds5010001","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T08:40:53Z","timestamp":1767602453000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Accessible Augmented Reality in Sheltered Workshops: A Mixed-Methods Evaluation for Users with Mental Disabilities"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2690-4887","authenticated-orcid":false,"given":"Valentin","family":"Knoben","sequence":"first","affiliation":[{"name":"Institute of Robotics and Autonomous Systems (IRAS), Karlsruhe University of Applied Sciences, Moltkestra\u00dfe 30, 76133 Karlsruhe, Germany"},{"name":"Institute for Anthropomatics and Robotics (IAR), Karlsruhe Institute of Technology, Kaiserstra\u00dfe 12, 76131 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malte","family":"Stellmacher","sequence":"additional","affiliation":[{"name":"Institute of Robotics and Autonomous Systems (IRAS), Karlsruhe University of Applied Sciences, Moltkestra\u00dfe 30, 76133 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4556-6959","authenticated-orcid":false,"given":"Jonas","family":"Blattgerste","sequence":"additional","affiliation":[{"name":"Faculty of Technology, University of Applied Sciences Emden\/Leer, Constantiaplatz 4, 26723 Emden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9569-5201","authenticated-orcid":false,"given":"Bj\u00f6rn","family":"Hein","sequence":"additional","affiliation":[{"name":"Institute of Robotics and Autonomous Systems (IRAS), Karlsruhe University of Applied Sciences, Moltkestra\u00dfe 30, 76133 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4551-2582","authenticated-orcid":false,"given":"Christian","family":"Wurll","sequence":"additional","affiliation":[{"name":"Institute of Robotics and Autonomous Systems (IRAS), Karlsruhe University of Applied Sciences, Moltkestra\u00dfe 30, 76133 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1117\/12.197321","article-title":"Augmented reality: A class of displays on the reality-virtuality continuum","volume":"Volume 2351","author":"Milgram","year":"1995","journal-title":"Proceedings of the Telemanipulator and Telepresence Technologies"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"589","DOI":"10.1177\/00187208221105135","article-title":"Effects of augmented reality-, virtual reality-, and mixed reality\u2013based training on objective performance measures and subjective evaluations in manual assembly tasks: A scoping review","volume":"66","author":"Daling","year":"2024","journal-title":"Hum.
