The inventor designed an umbrella that flies behind a person
The main idea of John Tse was to create a device that could follow the user without requiring physical control. The umbrella, which operates like a drone, allows the user to keep their hands free, which is especially convenient for using mobile devices or carrying bags. The ToF camera, unlike traditional optical systems, uses the principle of sonar to determine the distance to a person. It measures the time it takes for light to return from objects, allowing it to ignore visual interference
