    It requires a camera to do any remotely useful HUD stuff. If you want automatic translation, or in-world displays, it needs to see the world.

      Smartwatches don’t have cameras for the most part, smartglasses don’t need them either. Also a camera isn’t required for audio translation.

        I meant text translation obviously. You don’t need glasses for audio.

        And yeah, smartwatches don’t have cameras. They aren’t doing anything that needs them. AR, by definition, requires it to know about its environment. It needs a camera at minimum. You could have just smart glasses that can display texts or something, but AR needs cameras.

            What kind of information would my HUD show me, though? Like, idk, my heart rate? I don’t want my life to look like some first person shooter.

            Where I would get something out of it, would be e.g. when I am repairing stuff to show me where’s what (even while thinking about it, I am not sure 😅). Or when I am looking at something in a store to automatically pull up reviews or comparisons. Or showing a manual and highlighting the right screws when building furniture or such.

            Welp, not gonna shell out more than low digit hundred Euros for something like that, but all use cases which seem remotely cool…require a camera.

      In my fantasyland you would pair them with another device, like a phone, and it would do all the work. The glasses would basically be nothing more than a receiver and a display

        Yes, well that’s a fantasy when it comes to AR. It’s augmented reality, it needs to see the reality to augment it, else it’s just a static screen in front of your face. It isn’t anything new or interesting if you don’t have the camera in the front.
