Title: | Fortunettes: Feedforward about the Future State of GUI Widgets | Authors: | COPPERS, Sven LUYTEN, Kris VANACKEN, Davy Navarre, David Palanque, Philippe Gris, Christine |
Issue Date: | 2019 | Publisher: | ACM | Source: | Proceedings of the ACM on Human-Computer Interaction, 3 (Art N° 20) | Abstract: | Feedback is commonly used to explain what happened in an interface. What if questions, on the other hand, remain mostly unanswered. In this paper, we present the concept of enhanced widgets capable of visualizing their future state, which helps users to understand what will happen without committing to an action. We describe two approaches to extend GUI toolkits to support widget-level feedforward, and illustrate the usefulness of widget-level feedforward in a standardized interface to control the weather radar in commercial aircraft. In our evaluation, we found that users require less clicks to achieve tasks and are more confident about their actions when feedforward information was available. These findings suggest that widget-level feedforward is highly suitable in applications the user is unfamiliar with, or when high confidence is desirable. | Keywords: | Feedforward; Intelligibility; User Interface Widgets | Document URI: | http://hdl.handle.net/1942/28246 | ISSN: | 2573-0142 | DOI: | 10.1145/3331162 | Rights: | Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.
