While you might think of water jugs as something you drink out of, as demonstrated in Die Hard 3, these containers can also form a unique user interface. While much less violent, and not part of an elaborate bomb diffusion ruse, the Pour Reception device acts as a radio that uses capacitive sensing to interact with water in a much richer way.
Created by the team of Tore Knudsen, Simone Okholm Hansen, and Victor Permild, Pour Reception features internal speakers, an AUX input, a small guide, and two glasses resting on a smooth surface. You can turn the stereo on by adding water, and change stations by transferring water from one jar to another. Touching the glass fine-tunes the channel and filters the noise emanating from the unit. Finally, placing a finger in the water can pause the music momentarily.
Pour Reception is controlled by an Arduino Leonardo using the Tact library for advanced capacitive input. This input is then translated into commands using Wekinator machine learning software, along with a Processing sketch that allows the computer and Arduino to work together.
While a knob and switches would be more convenient for this type of interface, the setup is meant to cause you to reflect on how you engage with other digital items, perhaps inspiring new ways to interact with things that you otherwise take for granted.
As seen in the video above, the resulting build looks quite finished, and might even fit in in an upscale apartment as a piece of functional art!
