I/O Stickers is an electronics construction kit made up of adhesive sensors and actuators. Users can place these special electronic stickers onto contact points in pre-wired and pre-programmed pages, and the pages will transmit the state of the input (sensor) sticker to a corresponding output (actuator) sticker. Building the electronics is a simple matter of matching the sticker to the correct footprint. Users can design the interaction by choosing the sensor and actuator stickers, and then personalize the interface by decorating over the flat, electronic stickers with their choice of craft materials. I/O Stickers is designed to empower users to create electronics while also leveraging existing skills in craft, resulting in works that are creatively expressive as well as technically sophisticated.
