Abstract
A badge emits light to signal that the person wearing the badge has clean hands. The light is discontinued after a period of time to indicate that the person should proceed to wash his/her hands. The badge may emit light in a distinct manner (or generate sound) during a time period in which the person is supposed to be washing his/her hands. This distinct signal would be generated in response to user input, which should be entered only when the person wearing the button is beginning to wash his/her hands.
