Live with intent.

Guy doing the testing things responded to my concerns about privacy with "yeah, that's entirely fair"

Talking out loud to a pair of glasses feels stupid as fuck even in a room with an audience specifically for testing the glasses. I cannot imagine having to make requests of the glasses in any public space without feeling like a sellout dork on par with cybertruck owners.

Glasses accurately, but inefficiently (and imo insufficiently) described the people I was looking at, by mentioning them one by one, describing everything about their clothing in between. Maybe this is just me, but I feel like "three people standing in front of me" should be the first piece of information, not "a person in front of you with dark hair standing and wearing scrubs and white shoes holding a clipboard. A person to the left of you with long brown hair standing and wearing scrubs and white shoes. A person to the right of you-"

Glasses stop describing any time someone says anything and also, sometimes, if nothing happens at all. The wait time for it to resume is the perfect amount of seconds for it to feel awkward, which is impressive.

Glasses inaccurately described the office / eye test room I was in as a theater storage area, presumably because there was wood in it. Told it to stop doing this when it started describing everything in the room, fairly inaccurately based on this assumption.

Asked it to read a book page for me. Took three attempts at asking for it to do so. Took a picture of the page, processed, read the chapter number and three words, and stopped. Guy said sometimes you have to tell it to continue. Asked it to continue reading. It resumed describing the room from before.

How does anyone use these and think they're cool

I can see them hypothetically being an accessibility tool but honestly only if they had a keypad command input option. Having to state everything aloud is just so awkward, especially at the volume it needs to register. Like I don't want to sit in a nice restaurant and loudly instruct my glasses to read the menu to me just to get a handful of prices and no words. If there were a communication keyboard style mix and match for simple commands (or even just "read", "id", "find (option)") that could be sent and received quietly, maybe. MAYBE. but it utterly failed at the main things a low vision accessibility device is even for. AND they look stupid.
