Making sense of a body of data is a common activity in any kind of analysis. <italic>Sensemaking</italic> is the process of searching for a representation and encoding data in that representation to answer task-specific questions. Different operations during sensemaking require different cognitive and external resources. Representations are chosen and(More)
Although individual use of computers is fairly widespread, in meetings we tend to leave them behind. At Xerox PARC, an experimental meeting room called the Colab has been created to study computer support of collaborative problem solving in face-to-face meetings. The long-term goal is to understand how to build computer tools to make meetings more effective.
his discovery does not work. His helio-centric view allowed him to think that the sun, so near to the center of the planetary system, and so large, must somehow cause the planets to move as they do. In addition to this strong conjecture , he also had to generalize his findings for Mars to all planets by assuming that the same physical conditions could be(More)
WYSIWIS (What You See Is What I See) is a foundational abstraction for multiuser interfaces that expresses many of the characteristics of a chalkboard in face-to-face meetings. In its strictest interpretation, it means that everyone can also see the same written information and also see where anyone else is pointing. In our attempts to build software(More)
<italic>CommonLoops blends object-oriented programming smoothly and tightly with the procedure-oriented design of Lisp. Functions and methods are combined in a more general abstraction. Message passing is invoked via normal Lisp function call. Methods are viewed as partial descriptions of procedures. Lisp data types are integrated with object classes. With(More)
The selection of what to do next is often the hardest part of resource-limited problem solving. In planning problems, there are typically many goals to be achieved in some order. The goals interact with each other in ways which depend both on the order in which they are achieved and on the particular operators which are used to achieve them. A planning(More)
The analysis of DNA structure from restriction enzyme segmentation data has been viewed by molecular geneticists as one of their simpler analysis problems. This paper treats segmentation problems as a case study in the selection between data-driven and model-driven hypothesisformation. The main purpose of this paper is to set forth some useful(More)
