Context Sensitive Enterprise Applications for 3G Mobile Environments


Mobile technology is an integral part of today?s computing environments. Mobile devices like mobile phones and PDAs open up new opportunities for communication and information access. 3G wireless networks (especially UMTS) and the evolution of mobile devices will further extend these opportunities. A prerequisite for the commercial success of wireless technology is the availability of a rich set of mobile applications. But because of the heterogeneity of mobile execution environment the development of mobile applications with a high level of usability is a challenging problem. Applications have to be adapted to the varying resources and capabilities of mobile devices, the different quality of connections, different markup-languages as well as to individual user requirements.

In general applications can be adapted in two ways: manual and automated. ?The manual creation of multiple dedicated versions of and application results in good usability and design. The disadvantage is the (in most cases) unreasonable effort to create and maintain the consistency of all the versions of the application. Automated adaptation in contrast requires much less effort but in most cases usability and design of the application after the automated adaptation are unpleasant or even unacceptable.

In the project a combined approach is pursued. The aim of the project is the development of a device independent, XML-based markup language to describe user interfaces and information for their (semi-) automated adaptation to different devices. Therefore, at design time meta information is manually added to the user interface description. This meta information is used to control the automated adaptation process at runtime. During this process device specific versions of the generically described application are generated. This approach should result in a better usability after the automated adaptation while reducing the effort for the development of applications. Aims of the work packages are the examination of concepts for the description of meta data, the design of architectures for the processing of generic user interface descriptions and meta data and the validation of these newly developed concepts.
