35 seconds on my Rokid Glasses running Rokid Lumen, recorded straight from the HUD: a notification arrives, a quick 👍 reaction, a WhatsApp chat (demo data), dictation, the apps grid, the Controls tab, and the screen going off with a middle-finger double tap on the Meta Neural Band.

For this recording the band's commands were sent over adb and the dictated sentence is a synthetic voice, so the screen capture stays clean. In daily use it's the band on my wrist doing exactly the same thing.

New since the video:

- Write with the band: on any text field, pick Write and draw letters with a finger on any surface. The band's own handwriting model types them in. The same works as a keyboard for your phone's apps.

- Setup without a computer: the phone app installs the glasses app, arms it, and can claim the band with your Meta account. No adb, no PC.

- Gesture profiles on the phone (media, navigation, your own), copies of a web app (personal and work WhatsApp), typing from the phone, and log sharing.

Hey everyone,

I've been living with my Rokid Glasses for a while and I think they're some of the best hardware in this category. They're light, the HUD disappears when you don't need it, and since you can keep them charged while you're wearing them, battery stops being something you think about (power capsules).

What held them back for me was input. The touchpad on the temple works, but reaching for your head every time you want to scroll gets old fast.

Then the Meta Neural Band showed up, and that turned out to be the missing piece. So I built Rokid Lumen, an open source platform that turns the Rokid Glasses into a small app platform driven entirely by the band:

• Thumb swipe to move, index tap to open, middle tap to go back
• Middle double tap turns the screen off and on, like on Meta's glasses. Middle hold pauses the controls. Pinch and turn for volume
• A home with three tabs: your phone's notifications, a grid of apps, and controls (batteries of the glasses, band and phone, volume, brightness, do not disturb)
• Meta Ray-Ban Display-style web apps running on Rokid, offline (.mrbd.zip) or online. WhatsApp, Telegram and Reddit clients already run on it
• Notifications with a banner, an inbox grouped by app, quick replies, dismiss (it also clears on the phone) and a 15-minute snooze
• Dictation: focus a field and talk. Android recognizer, OpenAI, ElevenLabs, Azure, or Vosk fully offline
• Internet through your phone when there's no Wi-Fi, and the band can also control your phone
• Updates from GitHub, right from the companion app

This would not exist without these people, and I want to thank them properly:

• u/Monstreboss (Anezium), for Rokid Nexus and R08 Access Bridge. Nexus showed me what a platform on these glasses could look like: Lumen's notification relay, its sensitive-content filtering and the dictation engines follow his work, and R08 Access Bridge proved the glasses could be driven through an accessibility service and armed from the glasses themselves. Lumen's input, navigation, settings screen and self-arm are derived from it, and he kindly licensed it under Apache-2.0 so Lumen could ship in the open. Seriously, go star his repos and support him on Ko-fi.
• u/ajunior7 (callbacked), for kinesis, which cracked the Neural Band protocol: pairing, ownership, encryption and gestures.
• u/Equal_Chemist (896kb), for air-gestures, which brought the band to Linux and Android. Lumen literally grew out of it.
• hacha, for rokid-r08-wake, the self-arm technique.
• Meta, for the open Ray-Ban Display UI Toolkit. Every screen follows its design.

Before you try it, the honest part:

• Claiming the band with air-gestures unlinks it from Meta's glasses and app until you factory-reset it. The link is unofficial, so a band firmware update could break it.
• The first install needs a computer with adb, and setup takes about 15 minutes. (working on it).
• Android only. It's early, tested on my own glasses and phone.

If you build MRBD-style web apps, they should run here with little or no change. There's a developer guide and a skill for coding agents in the repo.

I'd love feedback, bug reports and app ideas. Not affiliated with Meta or Rokid.
