Upskirt Possibility at sitting(diagram)
Girls frequently caught up with such situation, on position of the knee together with the perspective spot between the upper limb of the skirt are 4 cm apart, but the distance from the hemline to your underwear is 12 cm, by the side looked of the
" exposed area " and the skirt will form a right triangle A B C (Diagram below)
If viewers eye E happen to be a straight line segment extended direction towards B to C ; Then point B will fall into his center field of vision, if we make E and vertical line to A and C, the vertical line segment extended straight line D and E makes a right triangle D, E, C can be similar with right triangle A, B, C.
If △ A, B, C , The A, B length is A, C 1/3 distance.
Therefore in C, D, E the D, E length also should be D, C 1/3 distance .
And because D, C is the contour interval between the viewer's eye and skirt.
Assume that this distance is 1.6 meters, then the length ( eye distance and the skirt height) X is 53.3 cm.
But if the height of the viewer is 170 centimeters when in a ordinary sitting posture, his eye and the skirt suspend actually can have 70 centimeters disparities.
