Motivated by studies of speech rate convergence, we conducted an experiment to examine whether user preferences for system pace are correlated with user pace. Subjects frst completed a series of trials to determine their user pace. They then completed a series of hierarchical drag-and-drop trials in which folders automatically expanded when the cursor hovered for longer than a controlled timeout. Results showed that preferences for timeout values correlated with user pace-slow-paced users preferred long timeouts, and fast-paced users preferred short timeouts. Results indicate potential benefts in moving away from fxed or customisable settings for system pace. Instead, systems could improve preferences by automatically adapting their pace to converge towards that of the user.

However, many users seem to be reluctant to switch to expert interaction. We hypothesize the cause might be the aversion of making errors. To test this, we designed two intermediate modes for the FastTap interaction technique, allowing quick confirmation of what the user has retrieved from memory, and quick adjustment if she has made an error. We investigated the impact of these modes and of various error costs in a controlled study (N=36). We found that participants adopted the intermediate modes, that these modes reduced error rate when error cost was high, and that they did not substantially change selection times. However, while it validates the design of our intermediate modes, we found no evidence of greater switch to memory-based interaction, suggesting that reducing the error rate is not sufficient to promote expert use of techniques.", "authors": { "1": { "first_name": "Alix", "last_name": "Goguey" }, "2": { "first_name": "Sylvain", "last_name": "Malacria" }, "3": { "first_name": "Andy", "last_name": "Cockburn" }, "4": { "first_name": "Carl", "last_name": "Gutwin" } }, "year": 2019, "uri": "http://iihm.imag.fr/publication/GMC+19a/", "pages": "1:1-10", "bibtype": "inproceedings", "id": 908, "abbr": "GMC+19a", "address": "Grenoble, France", "date": "2019-12-10", "type": "Conférences nationales avec comité de lecture sur texte complet", "booktitle": "Actes de la 31e conférence francophone sur l'Interaction Homme-Machine (IHM 2019)", "type_publi": "colcomlec" }]);
