Designer Michal Kohút created an interactive installation called ’0, 1′, which uses a person’s eye blinks as input to control the lights in the gallery. Using a pair of glasses with a sensor that reads reflections in the eye, the microprocessor is able to evaluate when the wearer blinks and quickly turns the lights off and on. This happens so fast that the person wearing the glasses doesn’t even notice the change. You can see the device in action in the video below:
