Description: “Knowledge Navigator 1987 mock-up. The device opened like a book, with the “spine” lifting the face to an easy reading angle, and acting as a carrying handle when closed. The dark circle at the top is a video camera similar to a modern webcam, the slot in the upper right holds a memory card, and the grills on either side of the screen are speakers. In one featurette, the screen is also shown acting as a scanner.”
