There are rhythms of action and response to all human-computer interactions. As we click, swipe, tap and sway to their beats, these rhythms intersect with the rhythms of our everyday lives. Perhaps they synchronize, perhaps they disrupt each other or maybe they dance together. Whatever their impact, our experience of these rhythms will colour our experience of an interaction design. Developing an understanding of rhythmic experience within an interaction design, requires a focus on methods that foreground temporal relationships, rhythmic flow, and rhythmic performance. These methods involve iterative cycles of first-person experience and third person observation. They also involve the production and analysis of representations of rhythm across multiple sensory domains. Like rhythm itself, the focus is on change and continuity, on the cyclic and the linear, and on the patterns of their movement across time.
