Meta Wearable Device Access Toolkit - Overview of the developer preview

A summary of two presentations from Meta (see links below) and some key takeaways/thoughts.

Meta Wearables Device Access Toolkit
Developer Preview: Introducing Meta Wearables Device Access Toolkit

Meta will soon release a new SDK to let developers build mobile apps that integrate directly with Meta AI Glasses — including the new Ray-Ban Display glasses.

𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 𝐏𝐫𝐞𝐯𝐢𝐞𝐰: Rolling out to a limited group of developers in phases throughout Fall 2025.

𝐅𝐮𝐥𝐥 𝐒𝐃𝐊 𝐋𝐚𝐮𝐧𝐜𝐡: Planned for 2026

𝐒𝐃𝐊 𝐈𝐍𝐂𝐋𝐔𝐃𝐄𝐒:

• APIs for:
  • Media streaming
  • Photo capture
  • Error handling
• Sample applications
• Testing options:
  • Developer mode — testing with real glasses
  • Mock device kit — testing without hardware (e.g., injecting video for simulation & E2E testing)

𝐍𝐎𝐓𝐀𝐁𝐋𝐄 𝐓𝐀𝐊𝐄𝐀𝐖𝐀𝐘𝐒
The Meta AI app manages the connection approval between your mobile app and the AI glasses. It’s unclear whether this extra step through the Meta AI app will make the setup process feel clunky or add friction for users.

The Mock Device Kit appears to support injecting video into an AI glasses simulator — potentially a major boost for both development and end-to-end testing. This isn’t possible in most traditional mobile app simulators.

For now, the SDK won’t support sending imagery to the Ray-Ban Display HUD or accessing gestures from the Neural Band. When those features arrive, they’ll unlock far more customized in-app experiences.
