A user experience-based approach to home atmosphere control

The complex control problem of creating home atmospheres using light, music, and projected wall-art can be reduced by focusing on desired experience, rather than product functions and features. A case study is described in which subjective interpretations of living room atmospheres were measured and embedded into a prototype display system. A personalization mechanism is proposed to manage individual differences in atmosphere ratings, enabling a user model to evolve over time. To create a meaningful and simple control mechanism for a wide range of users, three interfaces were developed and studied, ranging from concrete to abstract control and from structured to exploratory navigation.
