	abstract = {User frustration with information and computing technology is a pervasive and persistent problem. When computers crash, network congestion causes delays, and poor user interfaces trigger confusion there are dramatic consequences for individuals, organizations, and society. These frustrations, not only cause personal dissatisfaction and loss of self-efficacy, but may disrupt workplaces, slow learning, and reduce participation in local and national communities. Our exploratory study of 107 student computer users and 50 workplace computer users shows high levels of frustration and loss of 1/3{\textendash}1/2 of time spent. This paper reports on the incident and individual factors that cause of frustration, and how they raise frustration severity. It examines the frustration impacts on the daily interactions of the users. The time lost and time to fix problem, and importance of task, strongly correlate with frustration levels for both student and workplace users. Differences between students and workplace users are discussed in the paper, as are implications for researchers.},

	abstract = {Annotating photographs is such a time-consuming, tedious and error-prone data entry task that it discourages most owners of personal photo libraries. By allowing the user to drag labels, such as personal names, from a scrolling list and drop them onto a photo, we believe we can make the task faster, easier and more appealing. Since the names are entered in a database, searching for all photos of a friend or family member is dramatically simplified. We describe the user interface design and the database schema to support direct annotation, as implemented in our PhotoFinder prototype},

	title = {User Interfaces for a Complex Robotic Task: A Comparison of Tiles vs. Overlapped Windows},
	journal = {Institute for Systems Research Technical Reports},
	year = {1997},
	month = {1997///},
	abstract = {High complexity tasks, such as remote teleoperation of robotic vehicles, often require multiple windows. For these complex tasks, the windows necessary for task completion, may occupy more area than available on a single visual display unit (VDU). Since the focus of the robotic task constantly changes, modular control panels that can be opened, closed, and moved on the screen are invaluable to the operator. This study describes a specific robotic task and the need for a multi window interface that can be easily manipulated. This paper examines two multi-window management strategies: tiled (fixed size) and arbitrary overlap. Multi-window searches were performed using the two management styles and they were compared on the basis of search completion time and error rates. Results with 35 novice users showed faster completion times for the tiled management strategy than for the arbitrary overlap strategy. Over factors such as the number of windows available, the number of displayed windows workload of opening or closing windows, and effect of learning are discussed.},
