Data quality issues

EEG and HRV data issues

The accuracy of Pylot’s cognitive performance metrics relies on getting good-quality data from the HRV and EEG sensors. A few poor samples will have minimal impact, and these are easily handled by the apps that filter this data. However, problems arise when there is consistently poor-quality data. This is generally the result of:

Excessive movement
A poorly fitted band
Hair between the sensors and your skin

Fixing Data Issues

The most common fixes for data issue warnings are:

Tighten the band so it is firmly comfortable
Ensure the sensors are all in contact with your skin, and no hair is in between the sensors and your forehead
Avoid excessive movement. Lots of walking, jumping, etc may result in the sensors sliding over the skin and not getting good data
Position the sensors so the HRV sensor is in the centre of the forehead and the single EEG sensor is on the left.
