Tea is a popular beverage and drinking it can be pleasant and promote health. Drinking the right amount of tea can bring refreshment and promote digestion, but quoting too much tea can be harmful to the human body. Brewing water with trace minerals can promote the taste and flavor of tea, and grasping the right brewing temperature can promote the precipitation of tea nutrients. In this article, we introduce Tip Cup, an interactive system that helps users obtain information about their tea through sensors and encourages beneficial tea brewing. Tip Cup consists of a hardware teacup and an application. During use, the tea cup and the application detect and record tea parameters for real-time feedback. The app guides the user to drink a good quality and appropriate amount of tea. We conducted a preliminary user study of the Tip Cup, evaluating four college students. The results show that Tip Cup has a high acceptance level and promotes users to brew quality tea.
