In this short research project, the team (titled "chipmonks") built and tested various approaches to enhance personal digital communication with the use of sensors (specifically motion, touch and heartbeat) and various actuators (vibration, light or sound).Experiment in using the electric cunductivity of the human skin to detect human presense. Building sensor array to measure touch through glass surface. Testing a low resolution sensor on a sandblasted sheet of glass. Light as a way to imitate that presense. Strong light sources can penetrate skin. Blood with more oxigen is darker. It's possible to detect heart rate by measuring changes in light. The very few components needed to detect heart beat through glass surface. Heart of a Canadian. A hidden speaker attached to a surface creates the illusion of pulse. A surface emulating a pulse using a salvaged speaker.
