Mohageg, Michael F. (1999): User Interface Design in the Post-PC Era. In: Bullinger, Hans-Jörg (ed.) HCI International 1999 - Proceedings of the 8th International Conference on Human-Computer Interaction August 22-26, 1999, Munich, Germany. pp. 1137-1142.

1991

Mohageg, Michael F. (1991): Object-Oriented versus Bit-Mapped Graphics Interfaces; Performance and Preference Differences for Typical Applications. In Behaviour and Information Technology, 10 (2) pp. 121-147.

“This study used a standardized evaluation to compare two direct manipulation graphics interfaces. The interfaces investigated were: (1) object-oriented (vector) graphics; and (2) bit-mapped graphics (object-oriented graphics interfaces are not to be confused with object-oriented programming or object-oriented data bases). Experienced and novice subjects performed objectively derived benchmark tasks appropriate for two-dimensional graphics packages. Both performance and preference data were collected. Task completion time, aborted attempts, learning effects, and errors constituted the performance measures. For the preference data, subjects completed questionnaires to rate the interfaces on both an absolute and a relative basis. Results indicate that the object-oriented graphics interface is superior to bit-mapped interface for most tasks included in the benchmark set. The advantages of the object-oriented interface are especially pronounced for graphic manipulations such as rotation, resizing (scaling), and general editing.”

Mohageg, Michael F. (1989): Differences in Performance and Preference for Object-Oriented vs. Bit-Mapped Graphics Interfaces. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 385-389.

“This study used a standardized evaluation to compare two direct manipulation graphics interfaces: (1) object-oriented (vector) graphics and (2) bit-mapped graphics (object-oriented graphics interfaces are not to be confused with object-oriented programming or object-oriented data bases). Experienced and novice subjects performed objectively derived benchmark tasks appropriate for two-dimensional graphics packages. Both performance and preference data were collected. Task completion time, aborted attempts, learning effects, and errors constituted the performance measures. For the preference data, subjects completed questionnaires to rate the interfaces on both an absolute and a relative basis. Results indicate the superiority of the object-oriented graphics interface to the bit-mapped interface for most tasks, especially manipulation (e.g., scaling, moving, etc.) of graphics. The implications of these results for the use of direct manipulation graphics interfaces are discussed.”

Jorna, Gerard C., Mohageg, Michael F. and Snyder, Harry L. (1988): Performance, Perceived Safety, and Comfort of the Alternating Tread Stair. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 981-984.

“This study determined the perceived safety and comfort of an alternating tread stair and a conventional ships ladder. The alternating tread stair and the conventional ships ladder were also compared with respect to travel time and missteps. Subjects in military uniform ascended and descended both the alternating tread stair and the conventional ships ladder under load and no-load condition. In the load condition subjects performed trials while carrying a 9-kg tool box, and in the no-load condition trials were performed without the tool box. Results indicate that the alternating tread stair is perceived to be safer and more comfortable to use. Moreover, the alternating tread stair had significantly fewer missteps.”
