Smart glasses maker Even Realities today released its latest model, the Even G2 Display Smart Glasses. Featuring a monochrome display, stylish frames, and a unique ring controller, G2s are available now for $599. In contrast to Meta Ray-Ban Displays' "do-everything" approach, G2s are designed to do one specific thing: provide a smart display that only the wearer can see. Instead of a camera and speaker, the G2s feature a suite of basic apps, like a teleprompter and a map that you can see with a tilt of your head or a touch of your ring, packed into a pair of light, slick-looking designer frames. The idea is to create cool-looking everyday glasses that are useful instead of obtrusive.Improvements over the last generation of Even Realities smart glassesI reviewed Even Realities' G1 smart glasses (and even used them to scam a free drink) and found them impressive. Well, Even Realities says these are even better. It has improved on the micro-LED display from the last generation—which is pretty great already—to provide a bigger, sharper, and brighter display that includes two-level 3D, so certain information can appear closer to your field of view.Another new wrinkle is contextual AI: Switch it on during a conversation, and, according to the company at least, your glasses will silently display "suggestions for a more meaningful exchange" that only you will be able to see. If implemented correctly, this feature could be a useful way to augment your life—and if it can provide closed captioning for conversations, I'm fully on board. All of the above is controlled via a smart ring that lets you click, tap, and scroll. It also monitors your vital signs and health information, so you could display a live-read of your heart-rate or the number of steps you've taken that day. A new app infrastructure (and third-party support)Those are all welcome upgrades, but maybe the most interesting improvement isn't to the G2's hardware. On its website, Even Realities promises third-party app support is coming soon. G1 glasses do everything they're designed to do really well, but the actual use cases are fairly limited—a teleprompter is cool, but how often do you really give speeches? Opening the glasses up to developers who want to make something new on the Even OS could result in a must-have app, or at least improve apps the glasses already have. Even Realities nailed the basics with the G1, and these technical improvements and G2’s app support could turn a great concept into an everyday essential. That is, if everything works. Once I test 'em out, I'll let you know how they match up to what's being promised.
