However, the size of the AR field of view (AR-FOV), which is smaller than one\u2019s own FOV, might affect interaction with nearby floor-based holographic objects. The study\u2019s primary objective was to evaluate the effect of AR-FOV size on the required head orientations for viewing and interacting with real-world and holographic floor-based objects during standstill and walking conditions. Secondary, we evaluated the effect of AR-FOV size on gait speed when interacting with real-world and holographic objects. Sixteen healthy middle-aged adults participated in two experiments wearing HoloLens 1 and 2 AR headsets that differ in AR-FOV size. To confirm participants\u2019 perceived differences in AR-FOV size, we examined the head orientations required for viewing nearby and far objects from a standstill position (Experiment 1). In Experiment 2, we examined the effect of AR-FOV size on head orientations and gait speeds for negotiating 2D and 3D objects during walking. Less downward head orientation was required for looking at nearby holographic objects with HoloLens 2 than with HoloLens 1, as expected given differences in perceived AR-FOV size (Experiment 1). In Experiment 2, a greater downward head orientation was observed for interacting with holographic objects compared to real-world objects, but again less so for HoloLens 2 than HoloLens 1 along the line of progression. Participants walked slightly but significantly slower when interacting with holographic objects compared to real-world objects, without any differences between the HoloLenses. To conclude, the increased size of the AR-FOV did not affect gait speed, but resulted in more real-world-like head orientations for seeing and picking up task-relevant information when interacting with floor-based holographic objects, improving the potential efficacy of AR cueing applications.<\/jats:p>","DOI":"10.1371\/journal.pone.0311804","type":"journal-article","created":{"date-parts":[[2024,10,21]],"date-time":"2024-10-21T20:01:11Z","timestamp":1729540871000},"page":"e0311804","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["A larger augmented-reality field of view improves interaction with nearby holographic objects"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-4554-3628","authenticated-orcid":true,"given":"Eva M.","family":"Hoogendoorn","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daphne J.","family":"Geerse","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jip","family":"Helsloot","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bert","family":"Coolen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John F.","family":"Stins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8534-1124","authenticated-orcid":true,"given":"Melvyn","family":"Roerdink","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,10,21]]},"reference":[{"key":"pone.0311804.ref001","first-page":"12","article-title":"Holocue: A wearable holographic cueing application for alleviating freezing of gait in Parkinson\u2019s disease","author":"DJ Geerse","year":"2022","journal-title":"Frontiers in Neurology"},{"key":"pone.0311804.ref002","first-page":"4104712","article-title":"The beneficial effects of conventional visual cues are retained when augmented reality glasses are worn","author":"S Janssen","year":"2020","journal-title":"Parkinson\u2019s Disease"},{"issue":"4","key":"pone.0311804.ref003","doi-asserted-by":"crossref","first-page":"1095","DOI":"10.3390\/s20041095","article-title":"Avoiding 3D obstacles in mixed reality: does it differ from negotiating real obstacles?","volume":"20","author":"B Coolen","year":"2020","journal-title":"Sensors"},{"key":"pone.0311804.ref004","doi-asserted-by":"crossref","unstructured":"Miyake T, Al-Sada M, Zhong T, Wang W, Sugano S, editors.
