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)
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)
As the use of wirelessly connected embedded mobile devices grows in vast quantity, their situative use and context sensitive behavior becomes an essential feature. For the implementation of context awareness in mobile appliances, the need for the efficient gathering, representation and delivery of context information evolves. This paper describes issues(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(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)
GeoPointer presents a concept which enables a smartphone to act as a tangible pointer, in order to receive information about an object in the real world. By pointing to an object, such as a peak or a building, the user automatically receives context information about the selected object. The aim is to introduce the intuitive approach of pointing to objects(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)
Effective multitouch interaction does not reduce itself to a simple tracking of five fingers, there are several emerging effects that could prevent intuitive interaction in industrial appliances. This use-case describes practical challenges that were documented during the design and implementation of a holistic user interaction design in the domain of(More)
