The Lightbulb Computer

gist
Former Apple prototyper Guillaume Ardaud proposes the Lightbulb Computer, a speculative projector-plus-computer-vision device shaped like a large bulb that screws into any Edison socket or a portable base. Prototype demos show it projecting recipes, maps, photos, board games, and family boards onto surfaces, responding to voice and pointing, which he argues is a more social path than screens or smart glasses.
ideas
- Socket as platform. The bulb form fits a battery lamp base or any ceiling or wall Edison socket, and a ceiling mount sees and projects across a whole room.
- Four modalities. It hears voice commands, sees where you point, analyzes what its camera sees, and projects or highlights things in the real world.
- Shared, hands-free use cases. Kitchen timers and recipes, study questions, trip-planning maps, projected photos, board games, pointing to control smart-home devices, ambient bedside and hallway displays, and augmented physical maps.
- Against eyewear. Headsets and glasses are constrained in power and thermals, interfere with faces, and require everyone to own compatible devices; marketing shows shared content nobody in the room can actually see.
- A gap in projector history. I/O Bulb, LuminAR, Dynamicland, Folk Computer, and the Humane Pin all used projection, but none targeted everyday personal computing; privacy would need on-device processing and hardware camera guardrails.

“Modern visions for the future of human-computer interaction are excessively focused on smart glasses and headsets - devices that are constraining & socially awkward.”
“I call this vision the Lightbulb Computer: a device that combines a projector with computer vision, in the shape of a large lightbulb.”
“All the videos shown here are from a real - yet bulky - prototype setup.”
“And maybe most important of all, it feels fundamentally antisocial.”
