Project Name VizION - The VizClass Interface Operating Network
Team Members Dirk Groenveld, Mike Elkin, Falko Kuester and Tara C. Hutchinson
Project Sponsor National Science Foundation (NSF)



The rise of ubiquitous computing environments creates a need for middleware systems that facilitate spontaneous, reliable, and efficient communication between many different devices of varying complexity. By their nature, these environments have to manage components and elements entering and leaving the system unpredictably. As appliances grow in number and complexity, the middleware needs to adapt and remain responsive even in adverse situations. VizION is a middleware framework, specifically designed for ubiquitous collaborative educational spaces. VizION aims to address the challenges encountered in these environments, through a distributed approach, a network of nodes with little need for a centralized entity. Its decentralized approach helps avoid performance bottlenecks and potential points of failure that would paralyze the entire environment. VizION presents a simple, unified platform to the application developer, hiding many of the complexities of distributed environments, and thus allowing ease of system extension. The test-bed application of VizION is the VizClass project at the University of California, Irvine, an interactive classroom specifically geared towards digitally enhanced engineering education.


This research is supported in part by the National Science Foundation (NSF) under Grant Number EIA-0203528 and the California Institute for Telecommunications and Information Technology (Calit2) SURF-IT Fellowship Program. The above support is greatly appreciated.
