Model Assisted Creativity Sessions for the Design of Mixed Interactive Systems: A Protocol Analysis

Abstract. To help designers face the complexity of mixed interaction and iden-tifying original and adapted solutions, we developed and evaluated an original approach to interaction design. This approach, called Model Assisted Creativity Sessions (MACS), aims to combine the best elements of both a model of mixed interaction, and a collaborative and creative session. The objective is twofold: to support the exploration of the design space, and to establish a common lan-guage between participants. To assess the viability of this approach, we relied on a protocol analysis of the verbal recordings of two existing design situations. Results show that the model impacts the generation of ideas and that partici-pants use the model concepts to share their thoughts during the session
