Claim:
1. A recognition method for an input device including a plurality of electrical conductors located at different heights, applied to an electronic device with a capacitive touch screen which has a function of height detection, different input devices having different electric field height information, wherein the method comprises: obtaining a sequence of capacitance values by connecting/disconnecting the plurality of electrical conductors in the input device to/from a ground in a preset order, upon detection of a touch control operation of the input device; obtaining electric field height values as the electric field height information of the input device, wherein the electric field height values correspond to multiple capacitance values in the sequence of capacitance values according to a preset correspondence between the capacitance values and the electric field height values; and determining attribute information of the input device according to a preset correspondence between the electric field height information and the attribute information of the input device.
