Liam's idea is really good. I like the concept of Flow, even though it doesn't quite work for me.

Also, I think 600×600 is perfectly capable of displaying full sentences.

The real problem is text input.

Web apps on the Meta Ray-Ban Displays don't have text or voice input, and typing by swiping on a QWERTY keyboard is ... painful.

So I put together a small prototype that uses the glasses' gyroscope to continuously steer a cursor over a QWERTY keyboard.

Surprisingly, it worked... okay.

I don't think this is the right solution, but I was genuinely surprised by how usable it felt, so I thought it was worth sharing.

- Pinch to select the highlighted key
- Swipe Up/Down to adjust cursor sensitivity
- Swipe Left/Right to recenter the cursor

I'd love to hear what you think.

How did it feel to use? Would you prefer something completely different, or do you think head-controlled input has potential?

🏓 For context: A friend and I both got Meta Ray-Ban Displays, so we started Ping Pong Prototyping (PPP). One of us shares a demo, then it's the other's turn. This is my return to Liam's Flow.

u/Different_Poetry_849 made another great one with Planes, point at an aircraft and get info about it in AR.

We’ve been doing a lot of location-based prototypes that use the camera, the world around you, and head movement. So for my PPP return, I wanted to try something a bit different: reading designed around a glanceable display.

I made Flow, an RSVP reading app for Meta Ray-Ban Display.

RSVP stands for Rapid Serial Visual Presentation. Instead of reading paragraphs, words appear one at a time in the same place. I first came across it through an Instagram Reel and thought it was a really interesting way of processing information.

It feels like a good fit for Ray-Ban Display because paragraphs can be awkward in a small field of view, but one word at a time feels surprisingly natural.

Personally, I can read RSVP at 450+ WPM when focused. At around 300 WPM, I can still do other things while reading, which is the part I find most interesting.

Right now I’ve been testing it with daily news, stocks, a few public-domain books like Alice in Wonderland, and language switching. I did some research and RSVP does seem to work in other languages too, although English is by far the most researched.

Curious what people think:

Would you use something like this for news, articles, books, docs, or messages?

Is the value speed reading, hands-free reading, accessibility, or making glanceable displays more useful?

What features would make it actually useful?

This is my return to Planes, ball’s back on their side of the table.

I’ll put the demo link in the comments.

I've waited long enough, and  u/Far-Temporary6630 missed his chance to return after my Full Debug.

The score is finally 1:0. 🏓

It's my serve again.

I wanted to be the smartest-looking person on the hike, so I decided to build an app that shows mountain peaks and other prominent landmarks around me.

The problem? I couldn't really build and test it from home.

So I came up with this setup:

• Connected the GitHub repo to Cloudflare Pages using my own domain.
• Gave Codex permission to edit, commit, and push changes.
• Set up remote access to Codex from the mobile app.
• Left my laptop running at home and went on a 2-day hike.

While hiking, every time I wanted to add something or just spotted a bug, I simply asked Codex to fix it. Within moments, the changes were deployed, and I could immediately test them on the Meta Ray-Ban Displays.

It honestly felt like cheating.

I've never been more productive on a hike.

Your return, u/Far-Temporary6630. Don't miss your turn this time. 😄

Returning my serve, u/Different_Poetry_849**. 🏓**

Nice hike. Smart glasses that name mountains for you, very civilized.

Me? I stayed indoors and taught my glasses to throw sharp objects.

I linked the Meta Ray-Ban Displays to my Scolia Home 2 dartboard. The board already auto-scores every throw, so I figured: what if each dart could do something? So I built a little suite of minigames that live right in the display while you play:

• 🪨 Asteroid — every dart chips away at a rock hurtling toward you. Miss, and it gets closer.
• 💣 Bomb Defusal — hit the right segments in the right order before the timer runs out. Wrong wire, boom.
• ⭕ Tic Tac Toe — the board becomes the grid. Land your dart in the square you want.
• 🔐 Safe Crack — dial in the combination, one throw at a time.

There's also a guide built in to get you started.

These are first prototypes, mostly to answer a question I was curious about: how does it feel to play with a non-spatialized display? The MRBD HUD isn't full AR — it's a little heads-up panel, not anchored to the world. My honest takeaway: it works better than I expected. It definitely makes darts more playful. Having the game react in your periphery while you focus on the board is a surprisingly good loop.

Super big thanks to Scolia for partnering with me on this one! It all runs on their board and their API — the real-time throw detection is what makes these games possible in the first place. Couldn't have built it without them.

Lots more to come. Your turn, and no hiding on a mountain this time. 😄

Liam made another great one! The darts app looks awesome. I'd love to try it, but I don't actually own this fancy dartboard. Four games are a lot, too.

As my return, I finally got around to finishing an old prototype.

Today I happened to drive past Berlin Airport, so I stopped to see if it actually worked in the real world. I had to make a few tweaks cleaned up some UX details in Ikea parking, and once again, I was surprised by how well the Meta Ray-Ban Displays handled a purely AR experience.

Planes - an app for plane spotters. Point at any aircraft and learn everything about it.

I really like where this project is heading and would love to keep working on it. The only problem is I'm not a plane spotter myself.

If any of you are aviation enthusiasts, I'd really appreciate your feedback.

What would make an app like this genuinely useful?

• A personal library of all the aircraft you've spotted?
• Notes and comments for each sighting?
• A companion mobile app or website with more detailed information?
• Sharing sightings with friends?
• Something completely different?

I'd love to hear what would actually excite people in the plane-spotting community.

For MRBD developers

Even before I got my hands on the Meta Ray-Ban Displays, I noticed that AR content in other people's demos always seemed to "slide" whenever it was away from the center of the display. Only objects in the middle appeared to line up perfectly with the real world.

When I started building my own prototypes, I saw exactly the same behavior.

After questioning Codex, I discovered it had simply assumed a 58° camera FOV. I built a small debug tool and started testing different values in the real world.

My conclusion was that the monocular display has an effective FOV of roughly 12–14°.

The funny part is... it doesn't actually feel good to use.

With a realistic FOV, AR content aligns better, but it becomes much more jittery and you can fit very little information on screen. For both Peaks and Planes, I ended up rendering with a 30–33° FOV instead. It sacrifices alignment near the edges, but the experience feels noticeably more stable and comfortable overall.

I'm curious what other MRBD developers have settled on. Have you found a better compromise for AR-heavy experiences?

🏓 For context: A friend and I both got Meta Ray-Ban Displays, so we started Ping Pong Prototyping (PPP). One of us ships an app, then it's the other's turn to return. This is my return to Liam's darts app—now the ball's back on his side of the table.

I started the replacement process in March. Meta sent me the return label in April, approved my replacement, then canceled the original replacement order because of an internal mistake. In June, I had to start the entire process over again. Now I can’t even upload my prescription because of an issue on their end.

I think Meta took my prescription glasses, kept them, and still hasn’t fulfilled my replacement. I’ve been without my glasses for months while being sent back and forth between Meta and LensCrafters, with no resolution.

I did file yesterday with my Bank of America paid debit card last year picked up item Jan 2026 been with issue since March

Idk what to do ?

I want working item

Hey all! Excited to share the first emulator for the Meta Ray Ban Displays.

Like many of you, I've been building web apps since the dev kit dropped ~1 month ago, and kept running into the same problem that there's no easy way to preview them without loading onto the actual glasses. So I built one!

https://hud.xyz/emulator

Drop in any web app URL

Paste in your web app URL and it renders straight onto the glasses. Test your app's layout and colors without the physical glasses, then share clean screenshots for your demo once you're ready.

Accurate lens transparency

Accurately preview how your app looks on the MRBD lenses in different environments and lighting conditions (around 30-40% transparency I feel is pretty close to IRL).

Glasses mode or 1:1

Toggle between frames and the 600x600 pixel view if you want to see your app in the correct resolution.

Day and night environments

Flip between light and dark modes to check contrast and legibility in different conditions. The MRBDs use projectors to render their screens, so it's good to make sure your app is readable both indoors and outside :)

hud.xyz is still in v1, so stay tuned for more updates! If there's something you want to see simulated or tweaked, let me know.

Very welcome to feedback - bugs, feature requests, the sorts.

Reading technical books is hard. Unknown words, confusing phrases, and misunderstood concepts require opening your phone, starting Claude, and working with Sonnet through a series of exchanges to finally get it.

Refocusing on the reading after such a hard context switch can be difficult. Repeated enough times and your attention span starts to deteriorate.

Fix: The assistant deeply understands your book and answers your questions by voice while you read, sidestepping the current process entirely.

All you have to do is:

- Upload a PDF version of your physical book and start reading

- Say "Hey Lumos" along with your inquiry (e.g. "why does det(A)=0 mean the matrix loses volume?")

- Assistant researches the book and responds by voice

- Continue reading until you need help again

It's in extreme beta but works well enough where I won't read a book without it. If you're interested in trying it, please reach out.

Video demonstration coming soon.

Wore my Neural Band during a hot day last saturday and haven’t worn it since. When I took it off; these marks were red but I figured it would subside after a day or two… 5 days later, here we are. It’s not tender to the touch and doesn’t hurt but it definitely stands out. I put my apple watch on over to cover it for the day. The skin feels rubbery compared to all the non damaged skin around it.. Anybody else have this issue?

PSA for anyone who's had their glasses a while. Check your neural band! The white stuff isn't damage, it's just dead skin and dirt built up 🤢. I am planning on soaking it in lukewarm water and scrubbing it out with my fingers/nails. The band is IPX7 so water is fine.

Hey everyone, I’ve been building an early prototype called Mentor on Call for Meta Ray-Ban Display / Meta Display glasses.

The idea is an expert-on-demand assistant that lives on the glasses. You choose a mentor trained on a manual, checklist, or persona, then ask it questions about what you are seeing. For visual questions, the companion captures a still image, sends it to Gemini with the active mentor context, and the display shows a small avatar, response, and eventually a highlight over the part being discussed.

This clip uses a Miranda-inspired fashion-editor mentor because outfit critique makes the visual loop easy to understand. The bigger direction is more practical: repair manuals, machine setup, restaurant procedures, training checklists, or any situation where someone needs guidance while looking at the real world.

The design constraint I’m exploring:

- Web App stays lightweight and display-only: mentor picker, avatar, captions, image preview, targeting hints.

- Phone/DAT companion acts as the eyes, ears, and controller: camera/audio, Gemini calls, backend coordination. But they have a lot of design limitations around what is possible or not for this use-case like no continuous camera mirror; visual turns are user-triggered stills.

Small note: this is not available as an app yet. I’m posting it as an early prototype to get feedback from other builders and people thinking about glasses-native AI interfaces. If anyone is interested in helping test, shape, or eventually launch something like this, I’d love to chat.

This is my first web app, so it is definitely a little silly, but it was a really fun way to learn about the capabilities and limitations of building for Meta Ray-Bans Display and how I can bring my UI/UX skills into a more lightweight, glanceable interface!

Bbang (빵) helps you decide what kind of Korean bread to get when you cannot choose. You can spin through different Korean bakery breads, get a random pick, swipe to learn more about each bread, and use a nearby bakery finder to see where you might be able to get one. You can also save bakeries you have visited so you can keep track of favorites.

I can't share a public link yet because I am using the free tier of the Google Places API, but send me a DM if you would like to try it!

Hope to make more web apps soon 👍

I bought the Display last week in hopes to use for translation, particularly Ukrainian language. I understand it is not available yet, but even joining the Early access program, I only have access to the default languages it came with it. Are the other languages for the early access for everyone or just certain users? Here are my screenshots of what I have.
