Abstract

The present disclosure provides an electronic device input method and an electronic device. The method includes receiving a first type of input signal in an input area of the electronic device, and determining a first input area and a second input area based on the input area according to the first type of input signal. The first input area is used to receive a first type of input signal, and the second input area is used to receive a second type of input signal. The first type of input signal is different from the second type of input signal.
