We propose that an interactional perspective on how emotion is constructed, shared and experienced, may be a good basis for designing affective interactional systems that do not infringe on privacy or autonomy, but instead empowers users. An interactional design perspective may make use of design elements such as open-ended, ambiguous, yet familiar, interaction surfaces that users may use as a basis to make sense of their own emotions and their communication with one-another. With such tools, users are provided with power over their own data and the interpretation of it ? providing for privacy and autonomy. We describe the interactional view on design for emotional communication, and provide a set of orienting design concepts and methods for design and evaluation that help translate the interactional view into viable applications. From an embodied interaction theory perspective, we argue for a non-dualistic, nonreductionist perspective on affective interaction design. Author Keywords ...
