Recently、 some controversial news about priority seat happens frequently. Because there are some people in demand like women in early pregnancy and people in physical discomfort、 they cant be judged by their appearances. So、 we try to improve the situation to let people in demand can sit at ease or avoid priority seat being vacant when no one needs it. We design it by using the theory of the sensor light. We set up the sensor light with an button can be controlled by the people. When people sit on the priority seat、 the sensor light lights automatically. It means that they can yield their seats. However、 people in demand can push the button to turn off the sensor light to let others know they need the priority seat. After people left the priority seat、 the sensor light reset again. This device can reduce the controversy about priority seat、 and avoid priority seat being vacant when no one needs it.
