the categorization that I've made has been purely reactionary, to what exists, because I do believe that there's some holy grail, I don't, I don't even know if it's possible. I don't know how long it will take. But I do think that we can imagine one pair of glasses that are, you know, the Tony Stark, Edith glasses, they're slim, they're sexy, and they do absolutely everything that we could ever want them to do. And so probably as time goes on, there's going to be fewer categories as the technology gets better. And so the reason why we have multiple categories now is because there's a whole bunch of areas in which we have to make trade offs right now. And so companies are seeing this list of trade offs. And they're thinking about what use cases do we want to achieve with the glasses, and then, you know, deciding what trade offs to make, to best align with the use cases. And so just looking at all the glasses that exists now, you can kind of see a trend of the sort of categories that people end up falling into, based on the trade offs that they've made based on, you know, weight, and power and tether, and sensors and, and things. So, I mean, the the first category I think of the one I'm most excited about, and that we've mostly been talking about are kind of the head up display all day wearable info glasses that are focused mostly on providing information. So it's not really mixed reality, where there's, you know, direct mixing of physical light input and the augmented input. It's more, it's about the context, but it's text information or light image information. And so the trade off there is there's, you know, a lower resolution, Lower Field of View, often monocular, often monochrome, less sensors, maybe no camera, maybe microcontroller, instead of a high power compute device. But all those decisions are made so that we can get a pair of glasses that you can wear all day comfortably. And they don't need, you know, advanced visual experience, because they're just providing you with snippets of information at a low frequency. Another area we've seen is audio glasses, so they don't have a display. They don't have a camera, their main thing is they have a microphone, and they have speakers. And the main things that's for is usually listening to music, listening, consuming some kind of content like a podcast, or an intelligent assistant. So you have an intelligent assistant on your head, you can ask it a question. And it can provide you with with output, but you know your answer. So also screen glasses, which are, you know, a lot all of these kind of fade into each other. But the screen glasses are basically that they're designed for the use case of using them as a screen so you're supposed to watch stuff. So they usually have like, no sensors, or few sensors. They don't necessarily have tracking, and they're almost always tethered. Because to get that Good visual experience with a higher resolution and higher field of view and stereo scopic binocular rather, you don't have the weight and power budget for the compute, and batteries. So they're almost always tethered to a phone or a laptop, when you get to that kind of category, there's camera glasses, which have been around for a long time, which is just the half a camera, usually not much else. And the main focus is content creation is is filming and, and pictures, the health and fitness area is maybe doesn't doesn't deserve its own category. Haven't figured it out yet. But devices that are tailor made for a specific sport, or for health and fitness. And they're expected that you only wear them while you're doing that thing. And there's there's also Mr. glasses, which are hardly glasses, even today, if they're if they're actually mixed reality, combining the digital content with the real world, they need, you know, multiple cameras, you know, pose tracking, good display, good visual experience, a lot of compute power with low latency, a lot of just power requirements, they're almost always tethered, or they're a headset today to achieve that kind of use case. And then the last is like kind of Ophthalmic glasses, which are all about, like helping you see better. So there's examples of, for the people who are blind, to be able to help them to at least see a little bit better with kind of like a magnification, or there's kind of these tinting glasses that will automatically tint for you or those you know, maybe like a magnification glasses or something like that, that can help you see better. And then there's specialty, which is just the been I throw everything else in, which is usually just the glasses that are that are kind of head up display info glasses, but they're designed for one specific use case. They're kind of like an appliance, and they can't do anything else. They're designed not to do anything else. But this is the current bins that I've that I've created and place things in. And there's a bunch of examples of glasses that exists today that fit into each of those.
