Apple announced a new computer last week, to great fanfare. The Vision Pro is a computer that is worn on your face, but the novel aspect is how you use it. Rather than view the computer’s output through a physical screen, that output is projected directly into your eyes with two very small but high-resolution displays a very small distance in front of you. Rather than control the computer through a keyboard, mouse, or touch screen, the primary user interface is through eye tracking and gestures.

Just as they removed the stylus for screens when they launched the iPhone, Apple requires no physical controller to use the computer. The computer senses what you are interested in interacting with by watching your eye movement and then looks at your hands to determine what you want to do.
