Abstract: Disclosed are a dynamic display method based on an operating body, a computer-readable storage medium and electronic device. The method includes: determining a position of a to-be-displayed icon on a screen in response to an air operation performed by the operating body relative to the screen in space; displaying the icon at the determined position; determining a first movement physical quantity of the operating body in response to detecting the operating body moving; determining a second movement physical quantity of the icon on the screen based on the first movement physical quantity; and controlling the icon to be dragged on the screen based on the second movement physical quantity. Thus, a user can know whether the air operation is accurate or not in real time according to a moving track of the icon, which improves the user's sense of control and the accuracy of the air operation.
