Camera glasses have cameras for photo and video capture, but may not have displays. Mentra Live is the primary example.

​
Mentra Live

  • Camera: 1080p with streaming
  • Display: No
  • Microphone: Yes (with VAD)
  • Speaker: Yes
  • Buttons: Yes (press, double press, long press)
  • LEDs: RGB + white privacy light
  • WiFi: Yes
// Mentra Live capabilities
{
  modelName: "Mentra Live",
  hasCamera: true,
  hasDisplay: false,
  hasMicrophone: true,
  hasSpeaker: true,
  hasButton: true,
  hasLight: true,
  hasWifi: true
}

​
Building for Camera Glasses

Use capabilities to detect camera-equipped hardware and adapt the rest of your app experience. 
protected async onSession(session: AppSession, sessionId: string, userId: string) {
  const caps = session.capabilities;

  if (!caps?.hasCamera) {
    session.logger.warn('No camera available');
    return;
  }

  const camera = caps.camera;
  if (camera) {
    session.logger.info('Resolution:', camera.resolution);
    session.logger.info('Can stream:', camera.video.canStream);
    session.logger.info('Can record:', camera.video.canRecord);
  }
}
Camera capture, photo upload, and camera streaming are documented in the standalone Mentra Bluetooth SDK docs.

Camera And Streaming

Request photos and start camera streams from supported smart glasses.

​
Audio-First Interactions

Without displays, use voice, buttons, and LEDs for feedback. 
protected async onSession(session: AppSession, sessionId: string, userId: string) {
  await session.audio.speak('Ready');

  session.events.onTranscription(async (data) => {
    if (!data.isFinal) return;
    await this.handleCommand(data.text);
  });

  session.events.onButtonPress(async (data) => {
    if (data.button === 'select') {
      await session.audio.speak('Button pressed');
    }
  });
}

​
WiFi Connectivity

if (caps.hasWifi) {
  session.logger.info('Device has WiFi');
}

​
Best Practices

  • Provide clear audio feedback because camera glasses may not have displays.
  • Use button shortcuts for quick actions.
  • Use LEDs for brief status indicators when available.
  • Always check capabilities before enabling hardware-specific flows.
