What is the thumb-bridge troubleshooting test for INSIGHT headset functionality?

The Thumb-Bridge Troubleshooting Test is a procedure used to check the functionality of the Insight headset independent of head shape or fit.

1. Make sure the Insight headset is fully charged.

Do this by plugging the Insight charging cable into the headset, and then connecting the cable into a functional USB port on a computer or use a USB adapter to plug into an electrical wall outlet. (Note: If you use a computer make sure it does not go to sleep – the headset will not charge if the computer goes to sleep or is turned off.)
Let the Insight charge for a full 24 hours. Then move to the next step.
2. Connect the Insight via USB dongle or Bluetooth to a computer or mobile device running an Emotiv application.

Within the given application the Contact Quality map will display the contact quality of each channel corresponding to the Insight’s sensors.
3. Place the thumb of one of your hands over BOTH of the sensors on the Reference Arm. The Reference Arm is the black, flexible extension coming from the bottom, left side of the Insight. Make sure the thumb makes strong contact with both of the sensors, otherwise the test will not work.

4. While holding both of the reference sensors, start to gently squeeze. Now, using the other hand gently squeeze one of the other sensors so that your thumb makes strong contact with the sensor pad.

5. Allow for the headset to adjust and start capturing signal by waiting for 5 to 10 seconds.

6. On the Contact Quality Map, the corresponding channel of the sensor that is being squeezed should change from black to red or yellow, then green. The channel should stabilize and stay green as long as you continue to squeeze that sensor.

7. If needed, repeat this Steps 3 through 6 for each sensor to test for full functionality of all the channels.

* The Thumb-Bridge Test may be used for the T7 sensor/channel (the one touching the left temple). This sensor can’t really be squeezed, so instead simply place your thumb on the sensor while applying gentle pressure. The corresponding channel should change to green as described above.

If a certain channel/sensor is problematic and the Thumb-Bridge Test does not get it to turn green then remove the problematic sensor tip and replace it with another one that is functional. Proceed to run the test as described above. If the channel works after the sensor tip is swapped, then the problem is not in the headset itself but with that sensor tip in particular. Conversely, if the after replacing the sensor and the channel remains black on the Contact Quality Map then the problem is within the headset itself and not with the sensor(s).
