This sketch uses conductive silver ink to create capacitive sliders on paper. Three sliders can control Hue, Saturation, and Value to help a designer tactfully choose colors. The interface features a “tap in/tap out” button, so the user lifting their finger on the slider doesnt affect the color reading.
This interface is a sketch at bringing digital decisions, like RGB color,
into the physical world through tangible interaction.
The project features teensy 3.2’s touchRead() function for capacitive input.
As an attempt to reduce interference noise in the sensor system, a swatch of conductive fabric was added to the opposite side of the page; it was grounded to the the teensy. Sensor signal smoothing still needs works.
