The NIST Smart Space Project
About this document
The NIST Smart Space Laboratory has been created to offer assistance to industrial research and product development laboratories to face the numerous performance and interoperability challenges inherent in the Smart Work Spaces of the future. We believe that the shift to Pervasive Computing is already well under way and will have as much impact on industry and daily life as personal computing did. Our Modular Test Bed is designed to allow our industrial and academic laboratories to bring their technologies together for integration and performance testing needed.
Pervasive Computing refers to the trend to numerous, easily accessible computing devices connected to each other and to a ubiquitous network infrastructure. This will create new opportunities and challenges for IT companies as they place computers and sensors in devices, appliances, and equipment in buildings, homes, workplaces, and factories. Within a few years, embedded devices able to execute complex software applications, and use wireless communications will be the norm and their effective use requires distributed interfaces on numerous, small, and even invisible devices.
The second version of the data flow system focuses on advanced forms of human-computer-interaction, integrating wireless networks with dynamic service discovery, automatic device configuration, and sensor based perceptual interfaces. The objectives are to:
This middleware makes it possible to integrate components that were not intentionally designed to work together, such as speaker identification, and speech recognition systems. Many constituent technologies are under separate development in industry, so the issues of interoperability and integration are paramount. This project will develop metrics and reference material based on real implementations for industrial use. Important technologies include sensor-based collaborative interfaces using:
Standardization and measurements are critical to foster integration, interoperability, and the development of emerging technologies but are often not addressed by individual companies for economic reasons. The lack of common software infrastructure, tools to create, manage, measure, test, and debug pervasive services, standards in key areas such as service discovery, APIs, wireless networks, automatic configuration, and ad hoc transactional security, all currently impede widespread adoption of pervasive computing. Also, measurements, and tests developed and performed in a public forum allow competing research systems to be compared and improved to build on the best features of previous iterations. It is a long-term research platform that will provide a sensor-rich collaborative working environment. Sensor technologies include microphone arrays, video camera arrays, smart badges, I.R. room scanners, and possibly person position sensors.
The purpose of this document is to present the NIST Data Flow System II (NDFS-II) and to help the user to get started. It is dedicated to users, who develop client nodes and use the framework to transport data between them. This user's guide is also useful for programmers whose task is to intervene on the system code.
