Engin Ayaz, Tak Cheung, and Doug Kanter created HeartWave, a tabletop device which uses water ripples to visualize the heartbeat of two people at once. The sides of the tank are equipped with Polar heart beat sensors, which actuate electromagnets to pulse a fin, generating each wave. According to Doug, “variations in liquid and lighting allow for a range of unique HeartWave experiences.” The box is constructed from a plexiglass frame with blue foam, black plastic, and is coated with Magic-Smooth polymer finish. Not only did the group create the great video above, but they also painstakingly documented the process of designing and building HeartWave. It’s definitely a slick project, but they’re not quite satisfied yet. On their wish list is enhanced lighting effects, coding refinements, and better interactivity cues for the user. No matter what, it’s a nice piece!
