Meta revealed a wearable called Muse Charm for its Muse AI agent. The device is palm-sized and can attach to a keychain. It has a small screen showing the agent’s avatar. Users tap a fingerprint sensor to start talking to Muse. Zuckerberg said it is the fastest way to talk to Muse without glasses. The device packs the full Muse voice and avatar system. It is designed to keep users connected to Muse at all times. Meta still needs to finalize the component layout. Shipping is planned for December in time for the holidays.
