1. An accidental touch prevention method which is applied to a wearable device, wherein the wearable device comprises a touch control structure and a capacitive touch sensor configured to collect capacitance values of at least two touch channels whose distances from the touch control structure are not equal to one another, and wherein the accidental touch prevention method comprises:
when an event of triggering the touch control structure is detected, obtaining a capacitance value of each of the touch channels collected by the capacitive touch sensor;
determining whether the capacitance values of all of the touch channels conform to a preset distribution state of capacitance value, the preset distribution state of capacitance value being a distribution state of the capacitance values of all of the touch channels when the touch control structure is triggered under a condition of non-accidental touch; and
if not, determining that the touch control structure is accidentally touched, and not responding to the event of triggering the touch control structure,
wherein the obtaining the capacitance value of each of the touch channels collected by the capacitive touch sensor comprises:
using the channel value of each of the touch channels collected by the capacitive touch sensor; and
performing fitting according to a channel value range and the channel value of each of the touch channels to obtain the capacitance value corresponding to each of the touch channels, wherein the channel value range of each of the touch channels comprises a maximum channel value and a minimum channel value.
