LUMA

An (es)sense master research project by Koen Beljaars

This research project focuses on how to design for perceptive activity in artifacts in order for crossing in perception of expressivity between person and artifact to happen. It is part of the research of Deckers et al (2011), on designing for perceptual crossing between person and artifact. In their work they propose a series of design notions which are meant as a tool for synthesis when designing for perceptive activity in artifacts. In this research we follow a research through design approach in order to generate design specific knowledge on the application of these design notions when designing an artifact capable of showing expressivity through its perceptive behavior. We designed LUMA, an dynamic light design capable of expressing a variable level of excitement thought its perceptive actions. We conducted research using the LUMA design in order to investigate how the stage of perception of expressivity can be reached in an artifact and if crossing of perception of expressivity can happen over the course of interaction between person and artifact. For this we specifically investigate the relation between the perceived expressivity and the occurrence of a cross-influential interplay of expressivity between person and artifact. The results of our experiment show that clarity in variability of this expression is essential for this interplay to occur. We discuss possible changes to the design to improve the clarity in variability of expressivity as well as further research steps.
