Description:
Fountains, reflecting pools, and other water displays have a long history in art and architecture. In the fountain industry, an “interactive fountain” is one that guests can touch or walk inside of to get wet. This is counter to our typical definition of an interactive system which requires sensors to detect user actions, and an output that changes in response to these actions. In this work, techniques for making truly interactive water displays are presented.
Submerging Technologies is a collection of three interactive water displays (Figure 1) which demonstrate sensing techniques that exploit the electro-optical properties of water itself. Municipal water is fairly conductive, typically 30-1500 μmhos/cm. [CWT 2004]. This conductivity is sufficiently high that the water can be used as a capacitive proximity electrode. Municipal water is also very transparent, and can serve as an optical waveguide.
