Abstract: A processing method includes projecting a display content of an electronic device to a terminal device having a display output module through a connection channel; and acquiring sensing parameters through a gravity sensor. The method further includes in response to determining that the sensing parameters satisfy a support surface placement condition, processing input parameters based on a plane transformation strategy to obtain response parameters, the input parameters obtained by a touch sensing module for a focus displayed in an output area of the display output module. The method further includes controlling, according to the response parameters, a display position of the focus in the output area to respond to a movement operation, a moving direction of the display position of the focus in the output area being consistent with a direction of the movement operation of the operating body with respect to the reference.
