Figure 4
Vertical axis is FFT absolute power (uv2) and horizontal axis is 14 features; Left side bar charts (dark blue and green) are behavior of first-group subjects (right-handed men), first and eighth FFT absolute powers of right-turning are much more than left turning. Two up right bar charts (yellow and red) are behavior of second-group subjects (women), eleventh FFT absolute power of right-turning is more than left-turning and fifth FFT absolute power of left-turning is more than right-turning. Three down right bar charts (light blue and orange) are behavior of third-group subjects (people without driver’s license), first, fifth and ninth FFT absolute powers are more in left-turning than right-turning.
