Under the influence of COVID-19, we are spending more time together with the people we live with. The kitchen is the most common space where roommates have conflicts and is usually one of the major reasons for people to move out. These conflicts are usually caused by roommates' lack of communication over chores distribution, roommates' lack of responsibilities of doing chores, and their feeling of unfairness when doing too many chores. Our design is an integrated system including physical sensors, lights display, speaker unit, and an app. Working together, the system helps roommates distribute chores fairly, remind them of their responsibilities when necessary, and encourage their positive communications.
