The Lightbulb Computer

Guillaume Ardaud proposes the "Lightbulb Computer," a speculative device combining projector technology and computer vision in a lightbulb form factor that can be mounted in standard sockets or portable bases. Rather than relying on face-worn devices like smart glasses, this concept projects information directly onto surfaces in physical spaces, enabling hands-free interaction through voice commands and gestures for practical uses like cooking, studying, trip planning, and shared activities. The design aims to create a more natural and socially convivial alternative to screen-based computing by augmenting everyday environments with ambient spatial information.
