Meta has rolled out a major update for its Ray-Ban Display smart glasses, introducing a futuristic new typing system powered by air gestures and neural input technology.

The feature, called Neural Handwriting, had previously been limited to beta testing within apps like Messenger and WhatsApp, but is now becoming available to all users on both Android and iOS. It also works across Instagram and standard phone notifications, allowing users to search contacts, send messages, and reply without needing a physical keyboard.

The system relies on the included Neural Band accessory bundled with the $800 glasses. Using advanced surface electromyography (sEMG) technology, the band can detect tiny muscle signals generated when users move their fingers as if writing letters on surfaces like a desk, palm, or even their leg. The gestures are then translated into text input for the glasses.

The Neural Handwriting feature arrives as part of Meta’s broader Update 125 rollout, which also adds several other upgrades. A new display recording feature can now capture the in-display interface, the camera’s point of view, and surrounding audio together in a single video recording.

Navigation has also improved significantly. Maps now provide richer search results, expanded walking directions across the United States and major cities including London, Paris, and Rome, as well as saved home and work locations alongside voice-guided navigation.

Messaging and social apps are receiving upgrades too. WhatsApp now supports group video calls and live captions for phone calls, while Instagram gains improved Reels and direct message navigation. Facebook integration has also expanded with widgets for birthdays and sports updates.

One of the most significant long-term changes, however, is Meta officially opening the Ray-Ban Display platform to third-party developers. Through the Device Access Toolkit SDK for Android and iOS, developers can integrate glasses-focused features into existing apps or create entirely new experiences specifically for the wearable platform.

Developers can also build dedicated web apps optimized for the glasses, and early experiments are already showing unconventional use cases. Community-made apps reportedly include aviation utilities, grocery list managers, transit navigation tools, games, and even YouTube playback directly within the display interface.

With gesture typing, expanded app functionality, and growing developer support, Meta appears to be positioning the Ray-Ban Display as more than just a smart wearable accessory, moving it closer to a fully interactive computing platform.
