Come Closer describes a combined research and art installation using wearable technology and collaborative interaction to explore and challenge the sense of personal space and proximity to others. Participants become acutely aware of each other; aware of their presence in both physical and virtual space. They are encouraged to probe and investigate the boundaries that define personal space, to test them and to cross them. Interaction is defined entirely by position in a room, and the distances between them and others. The movements of the participants are logged and analysed for expected and unexpected behaviours.
