Driver distraction analysis based on FFT<br />
of steering wheel angle<br />
Driver Distraction causes a lot of (deadly) accidents every year<br />
R.I.P.<br />
Therefore, we focus on the steering wheel angle to detect<br />
<strong>and</strong> avoid distracted driving situations<br />

Frequency [HZ]<br />
By making a Fast Fourier Transformation of the steering<br />
wheel angle, we can see differences in the spectra<br />
between normal (green) <strong>and</strong> distracted (blue) driving<br />
• Average amplitude range from 1 to 7<br />
• Less steering corrections<br />
• Averge amplitude range from 3 to 12<br />
• Max value of amplitude much higher<br />
• Big problems with lane tracking
