Using a capacitive sensing arrangement, artists Tore Knudsen, Simone Okholm Hansen, and Victor Permild have come up with a way to interact with music with two glasses of water.
One pours water into a glass to turn the radio on. Channels can then be changed by transferring water from one glass into the other, and fine-tuned by touching the outside of container. Volume can even be adjusted by poking a finger into the water itself.
An Arduino Leonardo is used to pick up capacitive signals, and data is then sent a computer where a program called Wekinator decodes user interactions.
Pour Reception is a playful radio that strives to challenge our cultural understanding of what an interface is and can be. By using capacitive sensing and machine learning, two glasses of water are turned into a digital material for the user to explore and appropriate.
The design materials that we have available when designing digital artifacts expands along with the technological development, and with the computational machinery it is possible to augment our physical world in ways that challenges our perceptions of the objects we interact with. In this project, we aim to change the users perception of what a glass is – both cultural and technical.
