Engaging patterns: Challenges and means shown by an example

This paper presents first results of a research project whose goal is to develop a pattern language that enhances business software by motivating and engaging elements. The goal of the pattern language is to turn the soft and vague term of "emotions in user interaction design" into constructive design Guidance. The patterns are especially tailored for joy-of-use in business applications. The main contribution of this paper is the description of quality characteristics for this pattern language. They are illustrated by references to existing pattern descriptions and elaborating their deficiencies. This paper shows how these weaknesses were addressed in the pattern language
