The embodiment of the invention relates to a control method of an input device. The control method comprises the steps that a signal level judgment module determines whether an annular coil with the signal level larger than a first voltage threshold exists in a rough measurement feedback signal or not; if yes, the controller extracts a preset high voltage threshold value and a preset low voltage threshold value in the memory; the controller extracts a large voltage rough measurement coil and a small voltage rough measurement coil in the rough measurement feedback signals; the coil selection module is used for connecting the large-voltage rough measurement coils with the signal sending module in sequence according to the fine measurement instruction; the coil selection module is used for sequentially connecting the small-voltage rough measurement coils with the signal sending module through the phase reversal module; the signal receiving and processing module receives the accurate measurement feedback signal and sends the accurate measurement feedback signal to the controller; the signal level judgment module determines whether an annular coil of which the signal level is greater than a second voltage threshold exists in the accurate measurement feedback signal or not; if so, the controller extracts the maximum voltage fine coil and the minimum voltage fine coil in the fine feedback signal and generates an indication coordinate value.
