One of the most maligned features of the Apple Vision Pro is the screen on its front, called EyeSight, which shows an image of your eyes, recreating what they're doing inside the headset. The opinion of most the TechRadar team is that it's anywhere from "dystopian" to "an outright abomination" – but I think it's maybe the smartest new idea the headset has. And not only that, but the principle behind it is something I'd like to see more tech use, starting with the AirPods Max 2.
In software/user experience design, there's a concept called an 'affordance'. Since what a piece of technology is actually doing is usually hidden, the basic idea of an affordance is that it tells you what's happening, or it tells you how you can interact with something. So, the tabs on your browser are an affordance – the software doesn't organize them like that in the background, but a tab arrangement makes it easy to switch between them, and to see what you have open. The fuel gauge on a car is an affordance, telling you what's happening hidden deep inside it.
