Flow:towards communicating directional cues through inflatables

Current research in wearable technologies have shown that we can use real-time tactile instructions to support the learning of physical activities through vibrotactile stimulation. While tactile cues based on vibration may indicate direction, they do not convey the direction of movement. We would like to propose the use of inflatables as an alternative form of actuation to express such information through pressure. Inspired by notions from embodied interaction and somaesthetic design, we present in this paper a research through design (RtD) project that substitutes directional metaphors with push against the body. The result, Flow, is a wearable designed to cue six movements of the wrist/forearm to support the training of elementary sensory-motor skills of physical activities, such as foil fencing. We contribute with the description of the design process and reflections on how to design for tactile motion instructions through inflatables.
