ITR: Active Information Spaces based on Ubiquitous Computing

点击翻译按钮获取中文摘要

The project researches a new form of operating system to manage a model ofcomputing called an Active Space. It integrates physical spaces that containubiquitous computers into a computational environment that supports humanactivity and applications. With anytime/anywhere ubiquitous devices, theusers' view of the computational environment is extended beyond the physicallimits of a computer and is placed into the surrounding physical space,augmented with computers that sense and affect that space around the user.Applications become mapped not just to views associated with specificwindows in a monitor but instead to the physical environment. Therefore,the physical space, augmented with communicating computer devices, becomes adistributed computing system.Active Spaces have the potential for creating multi-billion dollarindustries. Automated surgery, collaboration and engaged learning are a fewof the compelling examples. Gaia, an operating system for Active Spaces,will accommodate diversity by exploiting standards for interoperation andcooperation. System services track, authenticate and support mobile userswith reconfigurable graphics, multimedia and Active Space applications. Aunifying object bus, component model, and adaptive stream model extends plugand play to distributed mobile ubiquitous computers cooperating to support acomputational environment within physical spaces like cities, buildings androoms.
