With the computational power of modern smartphones constantly increasing, resource intensive applications are becoming feasible to an ever growing extent. In this paper, we report on a research project recently started. Its aim is to develop an application for smartphones that combines pedestrian and public transport navigation including the computation of(More)
Efficient human-computer-interaction is a key to success for navigation systems, in particular when pedestrians are using them. Due to the increasing computational power of recent mobile devices, complex multimedia user interfaces to pedestrian navigation systems can be implemented. In order to be able to provide the best-suited interface to each user, we(More)
Several studies show that the use of landmarks is crucial for pedestrian navigations systems. Furthermore, there are well-defined landmark features like its visual salience. However, the assessment and the selection of landmarks especially in large scale indoor environments is rarely examined. We conducted a user study in the university of Regens-burg and(More)
In this paper, we outline a possible formalization of the semantics of the XML-based ODX language. ODX is a substantial part of the emerging automotive ASAM MCD standard, which describes a middleware layer between offboard diagnosis applications and onboard diagnosis services of electronic control units (ECUs) of cars. The contribution of our work is(More)
For the elderly, falls are among the most frequent causes of severe injuries or even death. Therefore it is highly desirable to develop methods for early recognition. Numerous indicators have been proposed and thoroughly validated, that allow medical staff to identify persons at a high risk of falling. However, these indicators suffer from pragmatic(More)
