“Smart” and “attentive” services using users’ context are going to be realized in future ubiquitous computing environment. Sensor network is receiving considerable attention as one of the key technologies to keep track of the users’ context in the real world. Conventional sensor network research mainly aimed at environmental monitoring. However requirements of the sensor network infrastructure ...

In ubiquitous environments the transition from data to knowledge is becoming significant as more and more data is captured by numerous, usually separated technologies. These technologies are labeled as automated agents, semantic web or ubiquitous computing. As information is data with a certain meaning and knowledge is information with understanding how to apply it in a certain situation, the n...

The area of activity identification is maturing well in the HCI and ubiquitous computing fields. However, although algorithm development is proceedings well, without publicly available datasets on which to compare results it is difficult to consolidate the disparate work being done. This problem exists because realistic datasets describing human activity are difficult and expensive to gather an...

This paper reports on a case study that was conducted to investigate infrastructure requirements for enterpriseenabled, ubiquitous workspaces of the future. We first set the context for future work environments by reviewing current research activities in the areas of intelligent interactive rooms and enterprise computing. The work reported in this paper involved integrating MIT’s Metaglue multi...

From earliest times, humans have developed strategies for increasing their ability to remember and commemorate significant events in the history of their communities. Epics have been created, memorized, and passed on through generations even before the development of written records. Monuments have also been built to commemorate important events. Stratagems for helping people to retain informat...
