Evaluation of User Interface Transcoding Systems

Users access the Web through an increasingly diverse set of devices, such as mobile telephones, personal digital assistants, notebooks and tablet PCs. Services and content need to be accessible by anyone, anywhere, anytime, and anyhow. Device independent authoring is the goal of service providers. This paper presents an abstract model in form of a finite state machine (FSM). The FSM is the basis for the comparison of user interface transcoding systems (UITS). Based on this abstract model we identify the strengths and weaknesses of these approaches on an architectural level.
