The software architecture of distributed systems is about to change due to new requirements of modern mobile devices. New network techniques, like ad-hoc radio communication or peer-to-peer networks allow mobile devices to sense their environment and to interact with other devices dynamically. This paper presents a cutting-edge way to describe objects and(More)
Software cockpits (software project control centers) provide systematic support for monitoring and controlling the activities in a software development project. Important aspects are to track progress, to visualize team performance, and to provide feedback about the quality of delivered results. Therefore, software cockpits integrate and visualize data from(More)
The growing availability of wireless LAN technologies together with the pervasive use of mobile and embedded computing devices gives strong raise for internet services adapted to context, particularly the location of their use. In multiuser cooperation environments for closed area communities like learning and teaching teams in wireless university campus(More)
The tracking of objects and humans has recently received a lot of attention as a tool to improve business processes, occupational and public safety. In wireless sensor networks location information is needed to put sensor readings into geographical context. In industrial environments wireless sensor networks can facilitate deployment of tracking(More)
The availability of e-Inc reading devices, such as Amazon's Kindle, and tablets like the Apple's iPad dramatically pushed the market for electronic books and magazines. The well known advantages of electronic content compared to printed media are instant delivery, multimedia capability, less weight and additional media related services, such as dictionaries(More)
Remote access to plant/machine HMIs has always been an area of great interest. A broad range of well-established solutions is available to fulfill the various tasks from remote operation to remote maintenance (e.g., VNC). Depending on the regarded solution, there are more or less strong demands on the respective client device. In the course of the gaining(More)
Current research on localizing objects and humans typically concentrates on a single technical solution in one of the following main categories: radio-based, acoustic, and image processing systems. Together with more mature systems (like GPS) numerous localization techniques coexist in isolation. But having a closer look on deploying localization systems in(More)
