... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested.

Eisenhut, Sandra M. and Beaton, Robert J. (1995): Micro Saint Modeling of Visual Displays and Controls Consoles. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 16-19.

An experiment was conducted to evaluate the feasibility of using a predetermined time system (PTS) with the simulation model Micro SAINT as a method for making design decisions for a navy electronic interactive display and control console. Prototypes for different configurations were created using a Macintosh workstation. Configurations varied across two levels of symbol set, color condition, and screen format for three different target density scenarios. A Micro SAINT simulation model, emulating a single integrated task performed by the operator for all 24 prototype configurations, was constructed. The model was validated by regressing predicted performance scores on actual performance scores obtained from six subjects operating the prototypes. The model also successfully predicted the performance of a second group of six subjects. Although the questions of how to acquire standard deviation data and task time distributions remain, the use of a PTS in network simulation modeling can provide objective data for console designs without incurring the high costs associated with actual prototype construction and testing.

Kahn, Michael J., Tan, Kay C. and Beaton, Robert J. (1990): Reduction of Cognitive Workload through Information Chunking. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 1509-1513.

Two experiments were conducted to determine whether grouping of icons on complex graphic displays reduces information processing loads, as measured by the Subjective Workload Assessment Technique and error rates. In Experiment 1, between 2 and 25 symbols were presented on a computer display. Participants were asked to chunk symbols under class labels and store these labels in short-term memory. Two different display formatting variables were tested: spatial proximity grouping of icons was manipulated across three levels, while temporal grouping was manipulated across two levels. Results suggest that display grouping helps operators organize, encode, and store information into task relevant chunks and, in turn, reduces subjective workload and error rates. Experiment 2 was similar to Experiment 1, except that participants were required to remember individual icon names (i.e., participants were asked to remember as many as 25 item names). Results suggest that for chunk formation, storage, and parsing tasks, display grouping may reduce subjective workload, but not error rates.
