the retail price for these will be around USD 350 or so. companies other than apple will launch similar glasses for about USD 189.
the Macrumors article does not indicate or hint or rumorize that there is any screen/display in these.
what these will be is simply a microphone and headphone system that allows you to interact with apps on your iPhone that you have with you in yr pocket or bag, via Bluetooth.
additionally there will be a camera with video capability as well, as the article says. like a Go Pro. the camera will provide info about the location you are in - the outdoor menu of the cafe, the mountains you see in the horizon what are those mountains names,
i don't think there will need to be an infrared camera, but that was rumored for AirPods to achieve the same thing.
not expensive.
your optician will be able to make standard optical lenses for these to fit your prescription and/or make them into sunglasses.
these glasses provide a way for you to record your surroundings as you move through them without holding up yr iPhone. so picture yourself playing with your dog, taking a video of it. picture yourself walking up the steps of Mont St. Michel.
however, these will not be released in the Macrumors rumored timeframe. Improved Siri will prevent them from being launched until more like 2027 Spring.
Vision Pro has the distinct disadvantage of your face being covered with a goggles kind of mask (even if an appearance of your eyes can be seen from the outside). these glasses allow you to be in the moment and interact with everyone at the party.
i hope apple would have the courage for there to be a small diode that would light up green to show people that you are in fact recording them. i hope it remains true to that.
an additional chip that would need to be built into the frames is a motion reducing sensor. so that your videos are not going left and right up and down so quickly or jaggedly with the motions of your head. apple already has a similar chip in the newer iPhones. non-apple versions of these frames would not likely have this motion reducing capability.
if the videos could be streamed, i imagine someone at the party/event could stream it to someone like grandparents who are not there, or someone in the hospital. or YouTubers doing live streaming in the streets of Tokyo.
the battery that is needed in the glasses would be AirPods sized. the heavy lifting done by the iPhone battery.
