Yet, previous studies havenot found a clear benefit, some even finding it detrimental. Wereport on the first study to control for two important factors, wordsuggestion accuracy and typing efficiency. Our accuracy factor isenabled by a new methodology that builds on standard metrics ofword suggestions. Typing efficiency is based on device type. Resultsshow word suggestions are used less often in a desktop condition,with little difference between tablet and phone conditions. Veryaccurate suggestions do not improve entry speed on desktop, but doon tablet and phone. Based on our findings, we discuss implicationsfor the design of automation features in typing systems.", "authors": { "1": { "first_name": "Quentin", "last_name": "Roy" }, "2": { "first_name": "Sébastien", "last_name": "Berlioux" }, "3": { "first_name": "Géry", "last_name": "Casiez" }, "4": { "first_name": "Daniel", "last_name": "Vogel" } }, "year": 2021, "uri": "http://iihm.imag.fr/publication/RBC+21a/", "id": 935, "bibtype": "inproceedings", "abbr": "RBC+21a", "address": "Yokohama / Virtual, Japan", "date": "2021-05-08", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "booktitle": "CHI 2021 - Conference on Human Factors in Computing Systems" }, { "lang": "en", "publisher": "Institute of Electrical and Electronics Engineers", "type_publi": "irevcomlec", "title": "OctoPocus in VR: Using a Dynamic Guide for 3D Mid-Air Gestures in Virtual Reality", "url": "https://hal.archives-ouvertes.fr/hal-03317991", "abstract": "Bau and Mackay's OctoPocus dynamic guide helps novices learn, execute, and remember 2D surface gestures. 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" }]);
