The immersion detection method may further include: if the number of times that the touch screen of the electronic equipment is triggered at the multiple points within the first preset time is determined to be smaller than or equal to the preset value, the multiple-point triggering information of the touch screen of the electronic equipment is detected again.
For example, if it is detected that the number of times that the touch screen of the electronic device is multi-triggered within the first preset time is less than or equal to the preset value, it may be determined that the electronic device is not in water, and the multi-point trigger information belongs to the normal trigger operation of the user, so that the state of turning on the touch response function of the touch screen of the electronic device may be maintained, and the multi-point trigger information of the touch screen of the electronic device may be re-detected.
