Feng, Jing and Spence, Ian (2008): Attending to large dynamic displays. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2745-2750. Available online

Although studies have shown that physically large displays bring benefits in performance and user satisfaction, the expanded field-of-view (FOV) places considerably higher demands on our cognitive capacities. Understanding how we process information over a wide FOV is increasingly important to optimize interface design. So far, however, empirical investigations are scarce. We present an experimental paradigm and framework for research with large displays and we report a preliminary experiment that explores attentional performance over a wide FOV. The paradigm simulates aspects of tasks that are facilitated by large displays. Our data suggest that processing abilities in the center and periphery are similar only if distractors are not present. With distractors, peripheral processing is disrupted and performance is poorer than in the center. In general, both accuracy and speed decline if the user must process information simultaneously in both areas. We discuss the implications for interface design, and describe further work that we are planning within this framework.

Gwizdka, Jacek and Spence, Ian (2007): Implicit measures of lostness and success in web navigation. In Interacting with Computers, 19 (3) pp. 357-369

In two studies, we investigated the ability of a variety of structural and temporal measures computed from a web navigation path to predict lostness and task success. The user's task was to find requested target information on specified websites. The web navigation measures were based on counts of visits to web pages and other statistical properties of the web usage graph (such as compactness, stratum, and similarity to the optimal path). Subjective lostness was best predicted by similarity to the optimal path and time on task. The best overall predictor of success on individual tasks was similarity to the optimal path, but other predictors were sometimes superior depending on the particular web navigation task. These measures can be used to diagnose user navigational problems and to help identify problems in website design.

Gwizdka, Jacek and Spence, Ian (2005): Indirect assessment of web navigation success. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 1427-1430. Available online

Despite much research on hypertext and web navigation, relatively little is known about the relationship between web navigation strategies and success. We present two exploratory studies designed to explore the relationships between several web navigation metrics that are based on similarity to an optimal path to predict task success. The data suggest that the relationships between these measures depend on the particular web navigation task.

Gwizdka, Jacek and Spence, Ian (2005): Predicting outcomes of web navigation. In: Proceedings of the 2005 International Conference on the World Wide Web 2005. pp. 892-893. Available online

Two exploratory studies examined the relationships among web navigation metrics, measures of lostness, and success on web navigation tasks. The web metrics were based on counts of visits to web pages, properties of the web usage graph, and similarity to an optimal path. Metrics based on similarity to an optimal path were good predictors of lostness and task success.

More and more we're being asked to live with technology that is technically reliable, because it was created to fit our knowledge of the physical world, but that is so complex or so counterintuitive that it's actually unusable by most human beings.

-- Kim Vicente, The Human Factor, p. 17.
