Page, Stanley R., Johnsgard, Todd J., Albert, Uhl and Allen, C. Dennis (1996): User Customization of a Word Processor. In: Tauber, Michael J., Bellotti, Victoria, Jeffries, Robin, Mackinlay, Jock D. and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 96 Human Factors in Computing Systems Conference April 14-18, 1996, Vancouver, Canada. pp. 340-346.

“The purpose of the study was to identify the customization changes users typically make to their word processor. Ninety-two percent of the participants customized their software in some way. Participants who used the software most heavily also did the most customization (p < .05). Most of the customization was done to facilitate the participants' work practices. The most common changes involved providing easier access to custom or often-used functionality. Button Bars seemed to provide an easy and effective means for participants to customize access to the functionality they wanted. Few participants customized the visual appearance of the interface.”

Johnsgard, Todd J., Page, Stanley R., Wilson, Robert D. and Zeno, Ronald J. (1995): A Comparison of Graphical User Interface Widgets for Various Tasks. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 287-291.

“The purpose of the present study was to compare user performance, accuracy and preference while using standard user interface controls or "widgets" to complete specific types of tasks. Radio buttons were significantly faster, accurate, and preferred than any other widget for the mutually exclusive selection tasks. For the non-mutually exclusive selection tasks, check boxes were significantly faster and preferred. These widgets were superior due to the fact that all possible options were initially visible. As the number of options increased, the time to complete each task also increased. A practitioner's table for selecting effective widgets for specific types of tasks is provided. Further implications for user interface design and research are discussed.”
