Bluetooth Connection Details:

  • Device Name: Use this reference when contacting support.
  • Battery Level: Shows the battery level of the OCOsense glasses (may take a few seconds to display).
  • Connection Strength: Displays the current connection status.
  • BLE RSSI: Reflects Bluetooth signal quality. A higher RSSI value indicates a stronger signal.

Tap the Sensor Data button to access the screen displaying real-time sensor readings.

Sensor Data Screen

On this screen, you can monitor and adjust sensor data for optimal performance.

  1. View Options:
    • Glasses Fit: For accurate data, the proximity sensors should be no more than 32mm (1.26 inches) from the skin. In Fit Mask view, red sensors indicate out-of-range, and green sensors indicate in-range. Adjust the glasses until all sensors appear green.
    • Face Expressions: After calibration (see the Calibration section), this view shows if the glasses are correctly mimicking the user's expressions.

  2. Check Data Streams: Navigate through the tabs to view real-time data for each sensor.
    • IMU + Pressure: Signals from the Inertial Measurement Unit (Accelerometer, Gyroscope, Magnetometer, and Euler angles) and the pressure sensor.
    • Nav X Cumsum: Cumulative sum of the X-axis navigation sensor signals.
    • Nav Y Cumsum: Cumulative sum of the Y-axis navigation sensor signals.
    • Nav X and Y: Raw navigation signals from both X and Y axes.
    • Prox: Signals from the proximity sensors.
  3. When finished, close the Sensor Data screen and tap the Settings (cog) icon in the top-right corner to manage additional options.
