Light switches ruin interiors. In 2026, we got rid of them. Using Conductive Paint based on graphene or silver, any surface becomes a touch panel. Lobby wall, reception desk, chair armrest — everything becomes an interface. We explore how to create invisible buttons under a layer of regular plaster and turn navigation into an interactive quest.
Drawing as Circuit
Paint works as wiring. We apply it as graphic patterns, logos, or hide it under a finish coat. Touching it with a hand closes a capacitive circuit, and a controller (Arduino/Raspberry) executes a command: turn on lights, call an elevator, or start a video presentation. It's magic: the wall feels your touch.
Interactive Navigation
Touch & Go
In the lobby, we draw a building map with conductive ink. The guest touches the desired office on the map, and an LED path on the floor lights up leading to it. It's intuitive and hygienic (surface is easy to clean, unlike buttons). The reception turns into a musical instrument: touching different desk zones changes the ambient sound.
