Dyson's new $499 toothbrush has a camera inside it, and the camera can't see through toothpaste foam. Which explains why Dyson is suddenly selling toothpaste. The camera is a 1mm macro lens with 100,000 pixels, tucked under the bristles. It shoots 28 frames a second into a model trained on 470,000 dental images, spots the gap between two teeth, and fires a jet of mouthrinse into it within 100 milliseconds. Flossing while you brush. Six years and 16 million lines of code to get there. Nearly…
Dyson trained an AI on 470,000 dental images and put it inside a toothbrush. With a camera. That flosses for you. In real time. It's called the CameraJet for $499. Launched today. A 100,000-pixel macro lens sits inside the brush head. It takes 28 images per second while you brush. The AI detects gaps between your teeth and within 100 milliseconds fires a precision jet of mouthrinse directly into the gap. It's computer vision doing your flossing. While you brush. Automatically. Only Dyson would look at a toothbrush and think it needs a camera, a machine learning model, and a jet engine.
