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.
