Claim:
1. A projection method, comprising: acquiring a target content to be projected in an electronic device; determining a projection parameter for projecting the target content, wherein the projection parameter comprises a beam changing parameter of projection beams of the target content at a light path changing module, wherein the light path changing module has a plurality of refractive indices or reflective indices, and the beam changing parameter comprises the projection beams being refracted and a target refractive index thereof, or the projection beams being reflected and a target reflective index thereof; adjusting a beam output mode of the light path changing module for projection beams of the target content based on the projection parameter; and based on the beam output mode, projecting, via the light path changing module, the projection beams of the target content into a first region of a projection carrier which is located away from the electronic device by a first distance, wherein the area of the first region varies with the beam output mode.
