Dropdowns, hierarchical menus, sliders, or scroll bars involve steering a pointer or a cursor through a tunnel; optimal design for these GUI elements should consider the Steering Law. MT = a + b (A / W) For a straight tunnel of fixed width, where Saw the summary, thought, “That sounds like Fitt’s Law”, was immediately gratified by the first sentence of the article. Models of interaction tasks are quantitative descriptions of relationships between human temporal performance and the spatial characteristics of the interactive tasks.

Alphabetical listings can work well when there is a well-known, common vocabulary for the terms used. Accot-Zhai Steering Law is an outcome and direct object of Fitts’s Law.. Fun fact: Steering law was independently discovered 3 times: in 1959 by Rachevsky, in 1971 by Drury, and in 1997 by Accot and Zhai. References 1. For example, the steering law is a core part of performance models on more complicated HCI tasks such as lasso operations, i.e., free-form selection on illustration software [18,[42][43][44]. Breaking Web Design Conventions = Breaking the User Experience . These issues are studied from a number of perspectives including that of … In Presence: Teleoperators and Virtual Environments, 13 … Checklist Design is a collection of best UI and UX you need to provide a complete, honest and rewarding experience for your users. Accot-Zhai Steering Law: Implications for UI Design Many users will attempt to move diagonally from Find to an item in the child menu, but, because in doing so their mouse will cross the area for Spelling and Grammar, the target submenu will be lost and instead the Spelling and Grammar one will be opened. The results generated during the testing phase are often used to redefine any problems the user may have and to insure the flow of the prototype makes sense to the user. In The Bulletin of Mathematical Biophysics 21:375-385 Accot, J. and Zhai, S. (1997).

Typical UX management activities involve defining an organization’s UX design language and strategy as well as managing the work processes around UX design. Prior to joining NN/g, she worked as a UX Designer for complex financial information systems and she also has extensive experience designing websites and games and in doing user research. A Designer’s Guide To The Tech Industry | Co.Design. (Accot & Zhai, 1999) (Dennerlein, Martin, & Hasser, 2000) Dropdowns, hierarchical menus, sliders, or scroll bars involve steering a pointer or a cursor through a tunnel; optimal design for these GUI elements should consider the Steering Law. The theoretical implications of the scale effects to the validity of the steering law, and the practical implications of input device size and zooming functions are discussed in the paper. Practical suggestions to improve your UI micro-interactions. Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics.This scientific law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. To overview of UI Design Issues . You must have javascript and cookies enabled in order to display videos. Enterprise App Design: Does iOS Fare with Android in terms of Security? Accot-Zhai Steering Law: Implications for UI Design When designing other UI elements that involve path-steering tasks, such as sliders, scrollbars, and video playback heads, remember that users will have a hard time achieving precision with such controls. The course highlights the design, development, and evaluation of human-computer interfaces, with an emphasis on usability, interaction paradigms, computer-mediated human activities, and implications to society. At this phase in the process, it’s all about observing the user testing the product and having them think out loud, as they are progressing through the test; how the user thinks, behaves and feels. Accot-Zhai steering law • Models the movement time of a pointer through a 2D tunnel • Can be seen as an extension to Fitts‟ Law Rashevsky, N. (1959). The Accot-Zhai Steering Law (discovered by HCI researchers Johnny Accot and Shumin Zhai, but also known simply as the Steering Law) is a corollary of Fitts’s Law.

That’s good design! Dropdowns, hierarchical menus, sliders, or scroll bars involve steering a pointer or a cursor through a tunnel; optimal design for these GUI elements should consider the Steering Law. Accot-Zhai Steering Law: Implications for UI Design. More enterprises are investing in mobile applications on platforms preferably iOS. Accot-Zhai Steering Law: Implications for UI Design . 2.3 Accot and Zhai’s Models Motivated by human-computer interacting tasks such as menu navigation, Accot and Zhai more recently investigated performance models in path-steering tasks (Accot, 2001; Accot & Zhai, 1997; Accot & Zhai, 1999; Accot & Zhai, 2001). 2019-08-02 Accot and Zhai derived the steering law as the limit of a sequence of infinitesimal Fitts tasks with only lateral constraints. Copyright © 1998-2020 Nielsen Norman Group, All Rights Reserved. We talked to Bonnie Jarvie of the Wall Street Journal about how technology has changed the way she works and her experiences leading a UX research team.

Observe, Test, Iterate, and Learn (Don Norman), Human Technology Teamwork: The Role of Machines and Humans in Good UX Design (Don Norman). We propose a Servo-Gaussian model to predict success rates in continuous manual tracking tasks. To help you navigate that sea of information, we make a cool list to share with you. [citation needed] He is known for his research specifically on input devices and interaction methods, swipe-gesture-based touchscreen keyboards, eye-tracking interfaces, and models of human performance in human-computer interaction. Since Accot and Zhai (Accot & Zhai, 1997), there have been quite a few HCI studies instigated or influenced by the law of steering (e.g. Beyond Fitts' law: models for trajectory-based hci tasks. Search UX microcopy → How to vastly improve the experience with thoughtful microcopy and contextualization. The Steering Law is an equation that predicts the efficiency of very common interactions; it describes the particular case of Mathematical biophysics of automobile driving. Because Fitts’ law is robust in the constraining direction [1, 4], the integral in the steering law transforms the aiming constraints in the free motion of It can be intimidating to get into user experience, but don’t fear: there’s plenty of help around. 11.04.2020 tatiana.
