The AI Pin is a wearable device designed by Humane Inc., intended to offload tasks typically performed on a smartphone. It is equipped with a virtual assistant, camera, projector, and touch-sensitive panel, allowing users to interact through voice, touch, and gestures. The device projects text onto the user's hand using a green laser and uses cellular connectivity for internet access, aiming to provide a screenless way to perform various tasks like making calls, taking photos, and answering questions.
