Professor Ellis -- The Collaboration Technology Research Group (CTRG)

The Collaboration Technology Research Group (CTRG) is a group of faculty and students at the University of Colorado (Boulder, CO) who are investigating the areas of groupware, workflow, and computer supported cooperative work. I will give an overview of the thrusts and goals of this group, and then discuss some of the ongoing research of the group. CTRG conducts both basic and applied research on theories, organizational studies, modeling, and systems implementation. We believe that the state of the art can best be advanced by an interdisciplinary approach that encompasses research as well as application of the research results to problems that exist in today's commercial environments. The talk will conclude with some pressing unsolved problems of the field.

Professor Fischer -- Making Learning a Part of Life - The Center for Lifelong Learning and Design (L3D)

Learning can no longer be dichotomized into a place and time to acquire knowledge (school) and a place and time to apply knowledge (the workplace). The Center for Lifelong Learning and Design (L3D) explores effective learning opportunities in the many settings through which people pass over the course of their lives and integrates distinct perspectives -- theory, system design, practices, and assessment -- in "making learning a part of life". The center (1) views learning as an ongoing social process in which one learns new knowledge as one needs it, (2) develops innovative intelligent systems to augment human creativity, (3) supports communities of learners, and (4) uses technology as a catalyst for fundamentally rethinking the future of learning and education.

Professor Nutt -- System Support for Applications Needing Negotiated Quality of Service

In the last few years our group has been prototyping a multiperson virtual environment using low-cost workstations interconnected with networks. This domain is designed to make use of interactive and on-demand continuous media in addition to a number of other tasks that fall on a spectrum between hard real-time and best-effort response. A brute force implementation of applications demands excessive system resources, even though the actual requirements by different parts of the application vary according to the way the virtual environment is being used at the moment. We are exploring approaches whereby resources are allocated by dynamically adjusting requirements according to the applications' current needs and the availability of system resources. This talk summarizes our work on the nature of the support required from the operating system and the concomitant obligations of application programs.

Refreshments will be served immediately before the talk at 3:30pm.
