An inductance and a magnetic texure are also included in housing unit 110, when magnetic texure produces relative to induction coil 116
One displacement variable, make induction coil 116 that there is an inductance variable quantity, the signal S according to corresponding to producing inductance variable quantity, sensing
Signal S caused by coil 116 is sent to the nib 112 of active capacitance pen 100 and then is sent to touch input equipment 50, removes
Outside this, signal S can be also sent to touch input equipment 50 by the present embodiment by induction coil 116.
Separately it should be noted that, the active capacitive touch pen 100 mentioned by the present embodiment need not be such as MCU or microprocessor
Control unit go to calculate the pressure value that active capacitive touch pen 100 is pressurized, the present embodiment is directly by the active electric
Nib 112 and the transmission signal S of induction coil 116 to touch input equipment 50, this measure of appearance stylus 100 can not only reduce entirety

Lift the ease of use of active capacitive touch pen 100.
In addition, above-mentioned signal S can be for example a string ripple signal, but the present invention is not limited system.
As shown in figure 1, then, carrying out step S120, received by the way that the inductive loop 53 in touch input equipment 50 is synchronous
At least signal S transmitted to the nib 112 and induction coil 116 for coming from active capacitive touch pen 100.
In the present embodiment, the inductive loop 53 in touch input equipment 50 is synchronously received from active capacitive touch pen
After at least signal S that 100 nib 112 and induction coil 116 is transmitted, further comprising the steps of, touch input equipment 50
The basis signal S of inductive loop 53 sensing result, show pointer position 54 (such as in the touch surface 52 of touch input equipment 50

Stylus is to favour touch input equipment 50, and the signal S (such as string ripple signal) that active capacitive touch pen 100 is launched is formed
Field region will not change.Similarly understand, when active capacitive touch pen 100 favours handwriting device 50, incline same
Active electric is rotated under rake angle θ and holds stylus 100, the field region that the signal S is formed (such as string ripple signal) still will not
Change, so still can be under abovementioned steps S140 calibration steps so that pointer position 54 is overlapped with pen tip position 56 (as schemed
Shown in 4).Therefore, touch input equipment 50 will not be influenceed by because active capacitive touch pen 100 is tilted and rotated, touch-control
Input equipment 50 remains to judge and calculates corresponding coordinate value.
In summary, in active capacitive touch pen calibration method provided by the invention, active capacitive touch pen
