Black screen when trying to record a HumanTrak test

When you start a new testing session in HumanTrak, you may occasionally notice a black or blank screen, which will usually self-resolve after approximately ten (10) seconds once the software connects to the camera.

If you are seeing a black screen for longer than ten seconds, this would indicate a connection issue between the camera and the HumanTrak system.

Use the below troubleshooting steps to resolve.

1. Exit your testing session.

2. On the home screen, click on Settings in the left menu, and confirm that the camera selected as the 'Body tracking camera' matches the physical camera that you have.

3. Ensure your laptop is running at the best performance levels by:
   1. having your laptop plugged in and on charge, and
   2. closing all applications on your laptop other than the HumanTrak software.

Once the above steps have been checked, try and start a new session.
