In this paper, we report preliminary findings from an experimental study in which twenty-eight users answered questions by performing strategic information searches on web pages. Pages, which varied in length from 100 to 850 words, were displayed on either a standard, desktop monitor (full-sized) or a palm handheld interface (small-screen). Overall, users(More)
An increasing amount of information is being disseminated to decision-makers via web interfaces. Because there is also an increase in the use of personal digital assistants (PDA's), future web sites must accommodate handheld access. With easy ability to synchronize content from the web with handheld systems, basic web design assumptions should be reexamined(More)
Goal-driven analysis is a methodology for determining what the user needs for solving complex problems. It is designed for use in systems with illstructured problems, such as performance support or decision support systems, rather than the welldefined problems addressed by conventional task analysis. It assists in the creation of systems that enhance and(More)
Through exhaustive two-hybrid screens using a budding yeast genomic library, and starting with the splicing factor and DEAH-box RNA helicase Prp22p as bait, we identified yeast Prp45p and Prp46p. We show that as well as interacting in two-hybrid screens, Prp45p and Prp46p interact with each other in vitro. We demonstrate that Prp45p and Prp46p are(More)
Human–information interaction (HII) for simple information and for complex information is different because people’s goals and information needs differ between the two cases. With complex information, comprehension comes from understanding the relationships and interactions within the information and factors outside of a design team’s control. Yet, a design(More)
The conventional techniques for task analysis derive the basic tasks that make up user actions. However, in the complex-problem solving environment, attempts to describe step-by-step actions breakdown because no single route to a solution exists. Although individual tasks can be defined, task-analysis normally results in the tasks being divorced from(More)
The technical communicator's job has changed from creating a document to creating information appropriate for a communication situation with multiple user groups and highly dynamic information needs. Many of the communication failure issues we consistently see have a root cause not based on how people interact with computers, but with a failure to(More)
This paper addresses the issues surrounding analysis and design which supports developing web-based information for use in situations which require supporting multiple levels of audience knowledge and ability. Firmly focused on communicating information, it addresses the analysis and design of information content requirements for systems that assemble(More)
