Here’s a poetic exploration of the humble light switch, highlighting what may be lost if everything becomes smart.
Let there be light switches – from dark living rooms to dark ecology
It means the resilient light switch, like the door handle, reveals the accumulated touch of all those gone before, a patina of presence. Juhani Pallasmaa said that the doorhandle is the handshake of the building; is the light switch the equivalent for the room? […]
Pallasmaa, in his The Eyes of the Skin, noted that touch is a key part of remembering and understanding, that “tactile sense connects us with time and tradition: through impressions of touch we shake the hands of countless generations”. Is this reach for the switch merely functional, then? A light switch can stick around for decades, as with the doorhandle. When you touch the switch, you are subconsciously sensing the presence of others who have done so before you, and all those yet to do so. You are also directly touching infrastructure, the network of cables twisting out from our houses, from the writhing wires under our fingertips to the thicker fibres of cables, like limbs wrapped around each other, out into the countryside, into the National Grid.
If we always replace touch with voice activation, or simply by our presence entering a room, we are barely thinking or understanding, placing things out of mind. While data about those interactions exist, it is elsewhere, perceptible only to the eyes of the algorithm. We lose another element of our physicality, leaving no mark, literally. No sense of patina develops, except in invisible lines of code, datapoints feeding imperceptible learning systems of unknown provenance. As is often the case with unthinking smart systems, it is a highly individualising interface, revealing no trace of others.
I think I now need to re-read Bret Victor’s take on the future of interaction design, that I mentioned earlier.
