A three dimensional touch control apparatus includes a touch panel and a controller. The touch panel receives a plurality of initial touch control actions respectively operated by a plurality of touchpressures in an initial period, wherein, each of the initial touch control actions is operated by touching a touch media to the touch panel along a moving direction. The controller is used to: in theinitial period, detect a plurality of capacitance sensing values generated at a plurality of positions along the direction respectively corresponding to each of the initial touch control operations;operate a multiple nonlinear regression operation to obtain a plurality of regression parameters according to the capacitance sensing values; and in a real detection period, receive a real touch control action, obtain a detected sensing capacitance value, and obtain a touch area signal by adjusting the detected sensing capacitance value according to the regression parameters. By means of the touchcontrol pressure judged through the compensated sensing capacitance value, the misjudgment phenomena can be reduced, and the touch control detection accuracy can be improved.
