: A Visualization Tool for Location Awareness to Support Informal Interactions, people in a single office, and the movement of people throughout the environment. We describe the context of the environment in which the tool is used, the features embodied in this tool, variations we have implemented for representing location and movement information, and some potential extensions for future versions of the tool.

The framework components include digital cameras running specific software, a distributed communication and storage infrastructure, tools for watching and annotating photographs. The framework also includes tools for notifying photographers when their pictures are accessed.

Enabling Context-Awareness from Network-Level Location Tracking,environments, applications will have to be adaptive, which requires context-awareness. We propose in this paper an efficient way to export context-dependent informations to applications by exploiting location knowledge available at the network level. This method is illustrated by a prototype using Mobile-IP and a context-aware Web browser.

Integrating PDAs into Distributed Systems: , and PalmORB, handheld devices seamlessly in a distributed computing environment. Componentized applications, adaptable middle- ware frameworks, and standardized protocols play a significant role in this new paradigm. We also describe an implementation within this paradigm using PalmORB, a CORBA client for the 3Com Palm devices.

The probes focus designers‘ attention onto successfully managing complexity and in coping with socio-economic influences on design practice in the real

The humble and somewhat fragmented PDA market will be swept aside as our need to consume overpowers our need to be organized. The ubiquitous Internet has taken the potential for these devices way beyond the niche of ele
