The amplification of biodata through dynamic textile displays opens the potential for novel ways of communicating our emotions, health and of understanding others. In this paper, we present HeartMe: a provocation of awareness in heart disease by using thermochromic displays. We present our design process to create three displays with different thermochromic textile patterns and heating circuits. Different variables were used such as heating up timing, cooling down timing and temperature in order to create dynamic and controllable interfaces with thermochromic inks. They interact with user's heartbeat rates, exploring the possibilities of thermochromic as social displays.
