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.
