Slider Swatch

Our Swatch deals with the question of how a simple switch with different triggers can best be put into the context of e-textiles. With the help of a button, you make contact between different tracks. Depending on where the button is located, different actions are triggered. To make it easier to use, we have chosen 3 different LEDs, which light up when the button touches the respective track. Our Swatch is technically easy to implement and simple to understand, even though it took a lot of work and effort to develop the idea. The Slider can be applied to different types of textiles at any time and is hardly noticeable because of its minimalist and clear design. Nevertheless, it convinces with its functionality, because it allows for seamless integration of electronic circuits using elements already available in textile production.

Thanks to Anna Blumenkranz and Irene Posch for helping us with the publication of the paper and the Augsburg University of Applied Sciences for providing us with material.



The hack of the ‘two sided button’ is cool. The slider swatch demonstrated is well crafted and documented. The concept is quite simple and I have yet to see it accomplished with this specific technique.
