Hammontree, Monty, Hendrickson, Jeffrey J. and Hensley, Billy W. (1992): Integrated Data Capture and Analysis Tools for Research and Testing on Graphical User Interfaces. In: Bauersfeld, Penny, Bennett, John and Lynch, Gene (eds.) Proceedings of the ACM CHI 92 Human Factors in Computing Systems Conference June 3-7, 1992, Monterey, California. pp. 431-432.

“Our on-line data capture and analysis tools include an event capture program, event data filtering programs, a multimedia data analyzer, and a retrospective verbal protocol recorder for use with the multimedia data analyzer. Off-line observation logging is also supported. Additional plans for development include the integration of an online time-synchronized observation logger, and time-synchronized eyetracking data recording. The tool set provides an integrated multi-source data collection, processing, and analysis system for: 1) comparing and evaluating software applications and prototypes; 2) evaluating software documentation and instructional materials; and 3) evaluating on-line training. The tools currently run on Macintosh computers and under Microsoft Windows. Plans are to port the tools to run under Presentation Manager and Motif.”

Hammontree, Monty, Hensley, Billy W. and Hendrickson, Jeffrey J. (1991): Event Capture and Analysis Tools for Graphic User Interfaces. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. p. 1165.

“This was a demonstration of a set of tools used to: 1) compare and evaluate software applications and prototypes; 2) evaluate documentation and instructional material; and 3) process video tape recordings of human-computer interaction (HCI). These tools include an event capture tool, which records events related to objects in graphical user interfaces, data filtering tools, which translate and aggregate user-generated events into meaningful characterizations of the interaction, and a multimedia data analyzer, which couples event logs and video recordings from HCI testing sessions.”

Hendrickson, Jeffrey J. (1989): Performance, Preference, and Visual Scan Patterns on a Menu-Based System: Implications for Interface Design. In: Bice, Ken and Lewis, Clayton H. (eds.) Proceedings of the ACM CHI 89 Human Factors in Computing Systems Conference April 30 - June 4, 1989, Austin, Texas. pp. 217-222.

“This study was conducted to provide evidence for the nature of visual search processes with menus, and to derive design principles for menu-based natural language (MBNL) interfaces to databases. The effects of window size, window activity, and query length were investigated. It was found that longer queries were performed faster with single active windows, but multiple active windows were rated as more 'natural'. Query times increased with query length, as did eye fixation frequencies, fixation durations, and dwell times. Errors were most likely to occur on the longest query. Fixation durations also varied with window size. However, visual behavior depended on the area being viewed and on the interaction between window activity and query length. In contrast with previous studies, it was also found that menus were not scanned randomly. However, scanpaths were less deterministic with multiple active windows and became even more unconstrained as query length increased. User interface design recommendations were derived from the findings.”
