By building a felt time repertoire, designers can sensitively feed a sense of time into their design work. And this in turn can help them produce an interaction gestalt that is richer, more sensual. My research on this suggests that this is not entirely easy, however. One has to develop a ‘feel’ for time. My research exploration began when I worked on designing a biofeedback data system, Affective Health, struggling with the tension and division between clocktime and the users’ unceasingly changing, ‘felt’ experiences. By turning to artistic practice, of music and culinary arts, I hoped to find keys to this question. Through connecting interaction-design research to these practices, I could start unfolding possibilities of temporal aesthetics in interaction design. I point to a space where designers can expand their understanding of felt time and playfully explore the sense of time that interactive systems and physical materials can deliver. Through the aspects below I point to the importance of being sensitive to felt forms and expressions of time to approach the temporal gestalt in interaction.
