Developing agile user interfaces for heterogeneous devices in business processes

Thanks to the increasing popularity of mobile devices, for accessing business process powered services people now can use various devices for different circumstances or tasks in order to have optimized performance. To support this kind of heterogeneous situation, user interfaces must be agile enough to adapt. In our research, we have identified five key requirements and five design guidelines to help developers to achieve this. Furthermore, we have introduced the concepts of user interface process and user interface service, where user interface development for business processes is well positioned in a bigger picture of Web Service and Service Oriented Architecture. Our research results have been presented by a case study developing a group messaging system.
