First, we developed a spatial AR remote collaboration platform that supports sharing the remote expert\u2019s HP or EG cues. Then the prototype system was evaluated with a user study comparing three conditions for sharing non-verbal cues: (1) a cursor pointer (CP), (2) HP and (3) EG with respect to task performance, workload assessment and user experience. We found that there was a clear difference between these three conditions in the performance time but no significant difference between the HP and EG conditions. When considering the perceived collaboration quality, the HP\/EG interface was statistically significantly higher than the CP interface, but there was no significant difference for workload assessment between these three conditions. We used low-cost head tracking for the HP cue and found that this served as an effective referential pointer. This implies that in some circumstances, HP could be a good proxy for EG in remote collaboration. Head pointing is more accessible and cheaper to use than more expensive eye-tracking hardware and paves the way for multi-modal interaction based on HP and gesture in AR remote collaboration.<\/jats:p>","DOI":"10.1093\/iwcomp\/iwaa012","type":"journal-article","created":{"date-parts":[[2020,7,27]],"date-time":"2020-07-27T13:15:52Z","timestamp":1595855752000},"page":"153-169","source":"Crossref","is-referenced-by-count":40,"title":["Using a Head Pointer or Eye Gaze: The Effect of Gaze on Spatial AR Remote Collaboration for Physical Tasks"],"prefix":"10.1093","volume":"32","author":[{"given":"Peng","family":"Wang","sequence":"first","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"},{"name":"These authors contributed equally to this paper"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoliang","family":"Bai","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"},{"name":"These authors contributed equally to this paper"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Billinghurst","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"},{"name":"Empathic Computing laboratory, University of South Australia, Mawson Lakes 5001, Australia"},{"name":"These authors contributed equally to this paper"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shusheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiping","family":"He","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dechuan","family":"Han","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Advanced Manufacturing Engineering, Chongqing University of Posts and Telecommunications, ChongQing 400065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haitao","family":"Min","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiqi","family":"Lan","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu","family":"Han","sequence":"additional","affiliation":[{"name":"Cyber-Physical Interaction Laboratory, Northwestern Polytechnical University, Xi\u2019an 710072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,7,27]]},"reference":[{"key":"2021070704035948400_ref1","doi-asserted-by":"crossref","DOI":"10.1145\/2702613.2732927","volume-title":"ShowMe: a remote collaboration system that supports immersive gestural communication","author":"Amores","year":"2015"},{"key":"2021070704035948400_ref2","doi-asserted-by":"crossref","first-page":"1151","DOI":"10.1145\/2851581.2892459","article-title":"GazeTorch: enabling gaze awareness in collaborative physical tasks","author":"Akkil","year":"2016","journal-title":"CHI Conference on Human Factors in Computing Systems-Late-Breaking Work"},{"key":"2021070704035948400_ref3","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/j.future.2017.12.055","article-title":"User experience and interaction performance in 2D\/3D telecollaboration","volume":"82","author":"Anton","year":"2017","journal-title":"Future Gener.
