Shard is a cycle trainer that transforms from a functional object to an artistic light installation when not in use. Shard creates an immersive experience through haloed lighting around the cyclist. Moving away from the prevalence of biofeedback interaction design based on screens and numbers, Shard influences behavior through ambient light and does not demand direct attention for consumption of information. Shard has two working modes: cycling mode and standby mode, in both the modes Shard gives ambient light based on input taken from sensors on the bike or data from the app.
