Nowadays people become busier than ever before. Even though people still have 24 hours in each day, it feels as if no one has “free time” to do anything. Thus, busy people prefer using their limited time to clean the most important area indeed. It is how the idea “dust map” came. Users can create the map by themselves and the appliance will collect data to predict or explain the level of cleanliness at home. In this way, users are able to know which area should be cleaned the most and which area can be skipped out of their limited time. The project is to redesign the UI of Philips SpeedPro Max, based on this futuristic idea.
