CONCEPT Affec tive Geometr y is a projec t about touch, play, and obser vation. I fr y is a small mechanical creature that lives in close proximit y to the body. By communicating and reac ting through vibrations, I fr y mirrors human physical states and tells time. The intimate and invisible interac tions draw attention of conscious and unconscious behavior to an ex ternal physical representation of the body – I fr y. Time becomes a private and physical language. Differentiating moments, mak ing time/body affec tive, giving them charac ter, the projec t presents an alternative way of time awareness and body expression.

TECHNOLOGY Affec tive Geometr y is felt through three vibration INTERAC TIONS motors in contac t with sk in. This exac t number of I fr y is inspired by pleasure humans experience motors presents an interesting range of vibration, BEHAVIOUR when touching and being touched. I t is physical time yet occupies a small sur face. The motors are proI fr y ’s responses and ex ternal physical representation of the body with grammed with difference in: acceleration strength or mirroring is diwhich one can be physically playful and expec t physical reof the vibration, time length of the vibration and vided into three sponse.
