The effect of the torsion spring coefficient on the accuracy of judgment (AOJ, %).

Stiffness	Index
	ODR	IP	SR	CI
K1	88.75	93.75	75	98.33
K2	85	91.25	75	95
K3	80	83.75	75	87

ODR: outline depression rate; IP: indentation proportion; SR: surface reflectance; CI: comprehensive index; AOJ: the accuracy of judgment.
