We first explore how users grasp 3D printed dials of different heights and circumferences in order to inform the form factor of shape-changing dials.

E.g., users are not always sure to answer how often they use trains. Enabling users to input their uncertainty is thus important to increase the data’s reliability and to make better decision based on the data. However, few interfaces have been explored to support uncertain input, especially with TUIs. TUIs are more discoverable than GUIs and better support simultaneous input of multiple parameters. It motivates us to explore different TUI designs to input users’ best estimate answer (value) and uncertainty. In this paper, we first generate 5 TUI designs that can input both value and uncertainty and build low-fidelity prototypes. We then conduct focus group interviews to evaluate the prototypes and implement the best design, SplitSlider, as a working prototype. A lab study with SplitSlider shows that one third of the participants (4/12) were able to discover the uncertainty input function without any explanation, and once explained, all of them could easily understand the concept and input uncertainty.", "authors": { "1": { "first_name": "Miriam", "last_name": "Greis" }, "2": { "first_name": "Hyunyoung", "last_name": "Kim" }, "3": { "first_name": "Andreas", "last_name": "Korge" }, "4": { "first_name": "Albrecht", "last_name": "Schmidt" }, "5": { "first_name": "Céline", "last_name": "Coutrix" } }, "year": 2019, "uri": "http://iihm.imag.fr/publication/GKK+19a/", "pages": "493-510", "bibtype": "inproceedings", "id": 862, "abbr": "GKK+19a", "address": "Paphos, Cyprus", "date": "2019-09-02", "document": "http://iihm.imag.fr/publs/2019/Interact19-SplitSlider-Greis.pdf", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "booktitle": "Proceedings of the 17th IFIP TC.13 International Conference on Human-Computer Interaction (INTERACT 2019)" }, { "chapter": 79, "publisher": "Frontiers", "type_publi": "irevcomlec", "lang": "en", "bibtype": "article", "title": "KnobSlider: Design of a Shape-Changing Parameter Control UI and Study of User Preferences on Its Speed and Tangibility", "url": "http://doi.org/10.3389/frobt.2019.00079", "journal": "Frontiers in Robotics and AI", "year": 2019, "uri": "http://iihm.imag.fr/publication/KCR19a/", "pages": "1-19", "volume": 6, "id": 863, "abbr": "KCR19a", "authors": { "1": { "first_name": "Hyunyoung", "last_name": "Kim" }, "2": { "first_name": "Céline", "last_name": "Coutrix" }, "3": { "first_name": "Anne", "last_name": "Roudaut" } }, "date": "2019-08-29", "document": "http://iihm.imag.fr/publs/2019/Frontiers19-KnobSlider-Kim.pdf", "type": "Revues internationales avec comité de lecture", "abstract": "Professionals such as sound engineers or aircraft pilots heavily use physical knobs and sliders on their interfaces.

To have advantages from both physical and touchscreen control interfaces, we explore design space of control interfaces and suggest design guidelines in the following steps. We first conduct a formative study with eight professionals who use knobs and sliders. Based on their feedback, we propose design requirements for future parameter control interfaces.
