Improving the Ring Signal Quality
The Ring Data Quality
If the Ring data quality is not adequate, check the following:
- Check GSR Connections: Make sure that the metal sensors are making adequate contact with the underside of the second phalanges of the index and middle fingers. (The phalange is the middle part of the finger between the joints). The elastic strap should be tight enough to keep the sensor in contact.
- Check BVP Sensor: Make sure the fingertip completely covers the optical BVP sensor. Verify that the elastic strap is snug but not too tight or this could cut off circulation and interfere with the signal. Note that BVP sensors will usually only work in the same place for 2-4 hours before local circulation will be reduced and sensor sensitivity could degrade. For long experiments, consider changing the sensor location or giving the participant a break.
- Movement Artifact: Note that both GSR and BVP data can be affected by movement artifact. The built-in IMU provides a mechanism for filtering out data that may be temporarily degraded by movement of the fingers.
- Battery Charge: Verify that the battery had adequate charge. Using the device with low battery power (indicated by a red LED) may degrade signal quality. We do not recommend using the device while charging, as this can introduce noise to the signal.
- Bluetooth Connectivity: If saving data to a computer or tablet, verify that the Bluetooth connection is not being interrupted or lost (or switch to microSD recording)
- Review Quickstart Guide: Review the Ring Quickstart Guide for setup instructions.
