The Lightbulb Computer
Points and comments are a snapshot, not live.
A designer proposes a projector-based 'Lightbulb Computer' as an alternative to headsets for spatial computing.
Guillaume Ardaud, a former Apple prototyper, presents a speculative device combining a projector and computer vision in a lightbulb form factor. It mounts in lamp bases or ceiling sockets and responds to voice, gestures, and vision to project interactive content onto surfaces. Example use cases include kitchen timers and recipes, map collaboration, board games, smart home control, and ambient displays. The author argues projector-based computing is more social than eyewear-based computing and less isolating than screen-based computing. All demos are from a real but bulky prototype using a 4K laser projector, a Mac, and a webcam.
What commenters are saying
Commenters are broadly intrigued, comparing the concept to projects like Dynamicland, Folk Computer, and MIT's SixthSense. The author engages directly, clarifying the prototype is real and emphasizing the UX-first design approach. Debate emerges over feasibility: some question the quality of camera-based text reading at angle and projection visibility in lit rooms. A few express privacy concerns, likening the device to a telescreen. The author notes interest in an open-source, locally-processed version. One commenter highlights prior art like Samsung's 2014 projector phone and the short-throw form factor.
