We adapt OctoPocus to 3D mid-air gestures in Virtual Reality (VR) using an optimization-based recognizer, and by introducing an optional exploration mode to help visualize the spatial complexity of guides in a 3D gesture set. A replication of the original experiment protocol is used to compare OctoPocus in VR with a VR implementation of a crib-sheet. Results show that despite requiring 0.9s more reaction time than crib-sheet, OctoPocus enables participants to execute gestures 1.8s faster with 13.8% more accuracy during training, while remembering a comparable number of gestures. Subjective ratings support these results, 75% of participants found OctoPocus easier to learn and 83% found it more accurate. We contribute an implementation and empirical evidence demonstrating that an adaptation of the OctoPocus guide to VR is feasible and beneficial.", "year": 2021, "uri": "http://iihm.imag.fr/publication/FHR+21a/", "id": 936, "bibtype": "article", "abbr": "FHR+21a", "authors": { "1": { "first_name": "Katherine", "last_name": "Fennedy" }, "2": { "first_name": "Jeremy", "last_name": "Hartmann" }, "3": { "first_name": "Quentin", "last_name": "Roy" }, "4": { "first_name": "Simon", "last_name": "Perrault" }, "5": { "first_name": "Daniel", "last_name": "Vogel" } }, "date": "2021-01-01", "type": "Revues internationales avec comité de lecture", "journal": "IEEE Transactions on Visualization and Computer Graphics" }]);
