When the fire breaks out, people’s first reaction is to open the door. Usually, the knob is very hot which indicate the danger inside the room. My design fits a temperature device in the knob which can measure the indoor temperature. Normally, the knob is green. But once the fire started, the color of knob would turn to harsh glare of red light which alerts people to the danger. So people can leave the fire site as soon as possible. As you can see, my design just transfers tactile stimuli to visual experience.
