Pinching and spreading gestures are prevalent in mobile applications today, but these gestures have not yet been studied extensively. We conducted an exploratory study of pinch and spread gestures with seated participants on a phone and a tablet device. We found device orientation did not have a significant effect on ...

As software systems evolve, new interface features such as keyboard shortcuts and toolbars are introduced. While it is common to regression test the new features for functional correctness, there has been less focus on systematic regression testing for usability, due to the effort and time involved in human studies. Cognitive ...

Several theories of how novices explore a new interface have arisen in HCI and have led to methods and tools for UI practitioners to predict users' behavior on proposed interfaces and improve their design ideas before implementation. These tools depend on obtaining quantitative estimates of information scent, which usually requires ...

In an age where HCI research is embracing softer approaches, we must not neglect the practical value of engineering research for HCI. This video challenges the assumption that engineering interactive systems takes a lot of effort with little pay-back or reward. We take CANCEL as an example. Not many people ...

In this study, we explore the role of age and fluid intelligence on the behavior of people looking for information in a real-world search space. Analyses of mouse moves, clicks, and eye movements provide a window into possible differences in both task strategy and performance, and allow us to begin ...

CogTool-Explorer 1.2 (CTE1.2) predicts novice exploration behavior and how it varies with different user-interface (UI) layouts. CTE1.2 improves upon previous models of information foraging by adding a model of hierarchical visual search to guide foraging behavior. Built within CogTool so it is easy to represent UI layouts, run the model, ...

We describe the motivation for research aimed at extending predictive cognitive modeling of non-expert users to a broader population. Existing computational cognitive models have successfully predicted the navigation behavior of users exploring unfamiliar interfaces in pursuit of a goal. This paper explores factors that might lead to significant between-group differences ...

Usability is recognized as a critically important quality of software, as evidenced by its inclusion in SE 2004: Curriculum Guidelines for Undergraduate Degree Programs in Software Engineering. However, many techniques for designing useful, usable and desirable software depend on knowledge and skills in the behavioral sciences, making them difficult for ...

Usability concerns are often difficult to integrate into real-world software development processes. To remedy this situation, IBM research and development, partnering with Carnegie Mellon University, has begun to employ a repeatable and quantifiable usability analysis method, embodied in CogTool , in its development practice. CogTool analyzes tasks performed on an ...

We studied the extent to which time-on-task is correlated with perception of usability for people who are familiar with a phone model and for those who are not. Our controlled experiment, conducted in Japan, correlated subjective usability assessments with time-on-task for expert and novice users on three different mobile phone ...

Predictive human performance modeling has traditionally been used to make quantitative comparisons between alternative designs (e.g., task execution time for skilled users) instead of identifying UI problems or making design recommendations. This note investigates how reliably novice modelers can extract design recommendations from their models. Many HCI evaluation methods have ...

Designers often have no access to individuals who use screen reading software, and may have little understanding of how their design choices impact these users. We explore here whether cog-nitive models of auditory interaction could provide insight into screen reader usability. By comparing human data with a tool-generated model of ...

Low-end mobile phones are becoming generally available throughout the world and the main window onto the Web. A large constituency for Web access is being created whose experience Web designers are not familiar with, particularly because of the central role of auditory, rather than visual access. This is analogous to ...

UI designers use a variety of prototyping tools, from paper and pencil sketching, to drag-and-drop mock-up tools (e.g., Balsamiq Mockups), to sophisticated suites of modeling tools and toolkits (e.g., iRise or dijit, the dojo GUI toolkit ). Many projects would benefit from quickly analyzing prototypes at an early stage without ...

Human performance models based on information foraging theory have proved capable of predicting navigation behavior on the Web. They can therefore provide a useful tool for Web site design. They may also be effective for modeling auditory navigation within a single Web page. Designers often struggle to accommodate this sort ...

Usability-supporting architectural patterns (USAPs) were developed as a way to explicitly connect the needs of architecturally-sensitive usability concerns to the design of software architecture. In laboratory studies, the Cancellation USAP was shown to significantly improve the quality of architecture designs for supporting the ability to cancel a long-running command, sparking ...
