Recommendations & Risk Indicators

The icons in the top-right corner provide real-time information on the platform's readiness for data collection.

Indicators

1. Glasses State

  • Green (Ready): No action needed.
  • Amber (Resetting): Glasses are currently resetting.
  • Red (Need Reset): Hold a neutral face for a few seconds until the glasses vibrate, and the icon turns green.

2. Bluetooth Settings

Glasses Battery Level

  • Green (>30%): Battery is sufficient for optimal data quality.
  • Amber (20–30%): Battery is low; consider charging soon.
  • Red (<20%): Critical low battery. For optimal data quality, maintain battery levels above 30%. Plug in the glasses if needed.

Connection Strength

  • Excellent (BLE RSSI > -55 dBm): Excellent bluetooth connection, no action needed.
  • Good (-55 dBm > BLE RSSI > -90 dBm): Signal strength is moderate; consider moving closer if connection is unstable.
  • Poor (BLE RSSI < -90 dBm): Critical low signal. Move the device closer to the OCOsense glasses, remove obstacles, ensure the glasses have over 20% battery, and try again. Check the average packet loss per minute in Settings.

Pre-Collection Checklist

Before starting data collection or troubleshooting issues, always:

  • Ensure a stable internet connection.
  • Verify Bluetooth connectivity through the Bluetooth screen.
  • Confirm the OCOsense glasses are connected (blue light flashing).
  • Check the glasses battery level (35% or higher). Glasses can be used while charging.
  • Verify sufficient iPad battery (35% or higher).
  • Confirm adequate iPad storage for temporary data storage.
  • Ensure the glasses are properly positioned on the face.
  • Disable iPad auto-lock to prevent interruptions in data collection.
