  abstract = {Understanding the work context of future system users is essential
	in requirements engineering. It is particularly crucial when developing
	ubiquitous systems that react on context changes. This paper discusses
	the need for in-situ requirements elicitation approaches to build
	mobile and context-aware systems. We identify three different levels
	of support: The first level covers contextual techniques without
	tool support. Second level support is based on existing RE approaches
	and mobile tools. Third level support utilizes context-aware tools
	receiving context-specific information to guide analysts in the field.
	These tools enhance requirements gathering for ubiquitous systems.
	We present a context-aware tool prototype for on-site scenario walkthroughs
	and discuss how the underlying scenario-based approach needs to be
	adapted. Our tool-based approach was tested in an initial evaluation
	study. Finally, the paper presents requirements for RE approaches
	supporting ubiquitous system development based on lessons learned
	from using level II and III tools.},
