Blackwell, Jason, Sheridan, John, Instone, Keith, Schwartz, David R. and Kogan, Sandra (2009): Design and adoption of social collaboration software within businesses. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2759-2762.
Social networking and collaboration sites are having a large impact on people's personal lives. These same applications, similar functions and related experiences are being adopted within businesses. This special interest group will address the issues around social collaboration software in the business setting. What is the value for the business and its users? How do you measure success? What strategic design and user experience issues are key for successful adoption? What roles do user experience professionals play in this type of social system?

Tetzlaff, Linda and Schwartz, David R. (1991): The Use of Guidelines in Interface Design. In: Robertson, Scott P., Olson, Gary M. and Olson, Judith S. (eds.) Proceedings of the ACM CHI 91 Human Factors in Computing Systems Conference April 28 - June 5, 1991, New Orleans, Louisiana. pp. 329-333.
We studied the use of an evolving interface style book to evaluate the role of such guidelines in the development of style-conforming interface designs. Although the designs were judged to be generally conforming, study participants had significant difficulty in interpreting the guidelines. Our designers were manifestly task oriented and impatient with extraneous material. They depended heavily on the pictorial examples, often to the exclusion of the accompanying text. We conclude that dependency on guidelines should be minimized, and that guidelines should be developed primarily to complement toolkits and interactive examples, focussing on information intrinsically unavailable through those vehicles.

Hill, Greg W., Gunn, William A., Martin, Shirley L. and Schwartz, David R. (1991): Perceived Difficulty and User Control in Mouse Usage. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 295-299.
This study was conducted to determine the relative perceived difficulty of performing different mouse tasks (pairings of mouse actions with button combinations). Right-handed individuals with various types of computer experience used a 3-button mouse to perform 49 simple target acquisition tasks. Perceived difficulty judgments varied with tasks. Significant groupings of tasks along the difficulty dimension were also apparent. For most mouse tasks, the left and center buttons were judged to be relatively easier to use than the right button. Additionally, chorded use of the left and center buttons was perceived to be easier than use of the right button alone. The results suggest that systems should both rely upon the right mouse button as a default setting for system-related functions. Other considerations for mouse usage are discussed.

Schwartz, David R. (1988): The Impact of Task Characteristics on Display Format Effects. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 352-356.
A study was conducted to determine how well the display format effects described by Tullis (1983, 1984) and the resulting prediction equations could be generalized to other display situations. Task complexity and visual monitoring load were identified as task variables which could potentially moderate the format effects and, thus, were varied factorially. The current study also sought to extend Tullis's findings to tasks where the use of several pieces of information from predictable display locations is required. In general, the data indicate the need to study Tullis's format dimensions more fully before using his regression equations to evaluate display designs for use outside the task situation in which the equations were developed. Also, subjects were unable to evaluate their performance accurately under alternative display designs. Their evaluations seemed to be determined mostly by the perceived ease with which information was extracted from the display. This outcome should serve as a warning to system designers. That is, empirical human performance research should be conducted when performance is the paramount design criterion and a validated prediction system, such as the one developed by Tullis for search, is not available.
