We track the real components on the expert\u2019s side to monitor the operations of an expert. We leverage a remote rendering technique that we proposed previously to relieve the rendering burden of the augmented reality end devices. By conducting a user study, we show that the proposed method outperforms conventional instructional videos and sketches. The answers to the questionnaires show that the proposed method receives higher recommendation than sketching, and, compared to conventional instructional videos, is outstanding in terms of instruction clarity, preference, recommendation, and confidence of task completion. Moreover, as to the overall user experience, the proposed method has an advantage over the video method.<\/jats:p>","DOI":"10.1145\/3429285","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T00:56:03Z","timestamp":1620780963000},"page":"1-23","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["An Augmented Reality Online Assistance Platform for Repair Tasks"],"prefix":"10.1145","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0110-4165","authenticated-orcid":false,"given":"Lu","family":"Sun","sequence":"first","affiliation":[{"name":"School of Electrical Engineering and Computer Science, University of Ottawa, Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hussein Al","family":"Osman","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Computer Science, University of Ottawa, Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jochen","family":"Lang","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Computer Science, University of Ottawa, Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2021,5,11]]},"reference":[{"volume-title":"Proceedings of the 2nd ACM Symposium on Spatial User Interaction. 113--122","author":"Adcock Matt","key":"e_1_2_1_1_1","unstructured":"Matt Adcock , Dulitha Ranatunga , Ross Smith , and Bruce H.
