In this paper, we present a framework for the user interface (UI) design of liquid UIs. These we define as UIs which utilize liquid, e.g. water, as a material for mediating the interaction or displaying information. Liquid UIs represent a novel type of tangible interface, which emphasizes experiental and aesthetic aspects. The framework defines design properties including the degree of contact with the liquid, liquid movement, the physical properties of the liquid and the containment mechanism.
