Usability is crucial for the user acceptance of software products. Some usability requirements influence software architecture and therefore should be considered early in the software development process. In this short paper, we propose the design of generic interaction scenarios that are mined from best practices (patterns). Our scenarios describe a user or system interaction as stimulus, the response of the system, and its assessment. We classified them in order to provide them in a knowledge base, as they are used for scenario-based analyses that assess usability properties of mobile applications.
