Abstract
In user-centered design, attention has shifted from improving usability and addressing ergonomic problems to wider perspectives such as experiences in everyday life. This shift has forced user-centered practitioners to evaluate and develop tools for finding new means of understanding user experience for design. Visual, playful and open-ended probes have raised fresh interest in the design community. In order to create a deeper understanding of this approach, this paper presents the fundamental qualities of probes and, based on empirical data and literature, describes four reasons for applying them in the product development and concept design context: for inspiration, for information, for participation and for dialogue.
