Video-based requirements engineering for pervasive computing applications: an example of preventing water damage

In today's software-intensive system development, negotia- tion between customer and supplier of required functional- ity is typically text-based. While text may be expressive enough to describe simple interactions between end-users and systems, it is severely limited when trying to unambi- guously describe complex interactions. Those potentially involve a plethora of stakeholders, mobile devices, and maybe even require revolutionary interaction paradigms. For such innovative systems, we propose to employ "video- based requirements engineering". Our film submission shows how a filmic representation of a scenario increases its understandability. The story is an example from the pervasive computing domain of home automation: The system protects the owner of an apartment from expensive water damage. After this exposition, the film shows how our tool may front-load a video-based analysis into subsequent system development steps: The same scenario is used in a short overview of the currently available tool support.
