Kurzbeschreibung (Abstract)

As of today, only simple office applications such as calendar and email applications are widely used on mobile devices - more complex applications still lack acceptance. The limited user interface features and the more difficult data input on mobile devices demand a redesign of complex applications to meet the needs of employees on the road. Especially in the context of enterprise applications, the complexity of information presented by typical desktop applications has to be reduced to the essential amount needed in a specific mobile usage scenario. This requires that the application is aware of the user context, including the device type and the current location. By using context information, parts of an application can be automated to minimize the required amount of user interaction. This paper describes the evolution of a typical enterprise application for Sales Order Entry towards a location-aware and personalized mobile application. Our implementation bases on a real word scenario for sales force automation and incorporates recorded customer feedback from an earlier prototype implementation. The major contribution of this paper is the integration of real-time location information with enterprise backend data. We use a Geographical Information System (GIS) based mapping service to access customer data depending on a location provided by an Enterprise Resource Planning (ERP) system. We will describe the mapping between GIS and ERP data and show how this approach improves the usability of mobile applications.
