A headgear includes a shell including a shell exterior and a shell interior; a visor connected to the shell; an electroencephalogram (EEG) sensor in the shell interior that generates a first signal indicative of state of a brain of a rider; a photoplethysmogram (PPG) sensor in the shell interior that generates a second signal indicative of blood flow rate in the rider's brain; an image sensor disposed in the shell interior that captures an image of the rider and generate image data; and a processor that: receives the first signal from the EEG sensor; receives the second signal from the PPG sensor; receives the image data from the image sensor; determines an attention score of the rider based on the first signal, the second signal, and the image data; and generates an alert signal when the attention score is below a pre-defined threshold value.
