Modern visions for human-computer interaction focus too heavily on smart glasses and headsets—devices that are constraining and socially awkward. This project explores an alternative: the Lightbulb Computer, a speculative device combining a projector with computer vision in the shape of a large lightbulb.
The lightbulb form factor allows it to be mounted in a portable lamp-like base, screwed into any Edison socket, or placed on a desk with a battery base. The ceiling offers a great vantage point to project anywhere in a room, and lightbulb sockets are a near-ubiquitous worldwide standard.
The device reacts to voice commands, sees where you point, analyzes what it sees, and projects content onto real-world surfaces. In the kitchen, it can pin widgets like recipes and timers on various surfaces—a natural way to work with wet or flour-covered hands. When studying, you get answers projected right where you need them.
For trip planning, it displays a giant map with gesture controls for panning and scrolling. You can send photos from your phone to project on any surface, play board games quickly with no setup, and control smart home devices by simply pointing. An ambient display next to your bed shows time, weather, and calendar without staring at a screen.
