Designer Guillaume Ardaud unveils speculative 'Lightbulb Computer' concept
Designer Guillaume Ardaud has published a speculative hardware concept called the Lightbulb Computer, which combines a projector and computer vision inside a standard lightbulb form factor. The device, shown via design prototypes and an accompanying video, responds to voice commands and pointing gestures, projecting interactive overlays like recipes, timers and answers to questions directly onto household surfaces.
