# Ray-Ban Meta Display glasses concept applications by L+R Explore a curated showcase of demo web apps bridging emerging wearable tech with real-world utility, bringing imagination to life on [Meta Ray-Ban Display glasses](https://wearables.developer.meta.com/docs). [DisplayGlasses.dev](https://displayglasses.dev) is a resource by L+R which includes a simulator for the Ray-Ban Meta Display glasses and a [getting started guide](https://displayglasses.dev/docs). Built by the team at [L+R](https://levinriegner.com). **Legend** | | Status | | Feature | | Feature | |:---:|---|:---:|---|:---:|---| | ✅ | Working on the glasses as described | 🎙 | Voice control through Meta AI (WebMCP) | 🔊 | Synthesized sound (Web Audio, no audio files) | | 🔌 | Working, but depends on a live third-party API or server | ✍️ | Text entry through neural handwriting | 🎞️ | Animation loop (requestAnimationFrame) | | 🧪 | Concept: real interface, simulated data or service. Its README has a “Making it real” section | 🧭 | Head motion and orientation (gyroscope / IMU) | 🖌️ | Canvas 2D / WebGL drawing | | | | 📍 | Location (GPS) | 🧩 | Inline SVG graphics | | | | 🎤 | Microphone or speech recognition | 🌐 | Calls an external API or live data source | | | | 📷 | Camera | 📡 | Real-time connection (WebSocket) | | | | 🔗 | Deep links between apps | 🤖 | AI model in the loop | | | | 💾 | Saves locally on the glasses | | | **Input on every demo:** the Meta Neural Band and the temple touchpad. Swipe your thumb along your index finger (or the touchpad) for ▲ ▼ ◀ ▶, pinch index finger to thumb to select, pinch middle finger to thumb to go back. Demos marked ✍️ also take text through the glasses' neural handwriting. Web apps get exactly these inputs: wrist rotation, pinch-and-hold scrolling and custom gestures are reserved for the system, and there is no vibration or haptic feedback. **Under the hood, every demo** is vanilla HTML, CSS and JavaScript with no framework and no build step, uses CSS animation for transitions and focus, self-hosts its fonts, works offline through a service worker, and has a QR code in its README to add it to your glasses. Previews are the raw 600×600 lens output. ## Hosted demos ### Primary demos > UI polished and complete.

It applies the additive waveguide blend (plus-lighter) over a real-world background image, so you can judge contrast and legibility without a physical device. Try it live: [https://displayglasses.dev](https://displayglasses.dev) Features: - Load any URL into the simulated 600x600 HUD - Drag to reposition, resize the display - Swap background scenes or upload your own image/video - Adjust HUD brightness, size, and background brightness - Press **H** to hide all UI overlays for clean screen recordings Meta also ships an official **Display Simulator** Chrome extension with its [Web Apps AI toolkit](https://github.com/facebook/meta-wearables-webapp): a 600×600 additive-display frame with D-pad input, display tuning, recording, and a QA checklist. Use it alongside the L+R simulator for day-to-day testing; neither replaces a pass on the glasses. ## Running an app locally ```bash cd python3 -m http.server 8080 ``` Open `http://localhost:8080` in Chrome, set the viewport to 600x600 via DevTools, and navigate with arrow keys. ## License MIT — see [LICENSE](LICENSE).
