A learning method to be implemented by an electronic device including a processor and a display unit and cooperating with an imaging frame includes: storing a set of image data related to a virtual 3D image of an object, and a total score associated with the object; displaying, by the display unit, image parts respectively on display areas that surround a central area according to the set of image data, in a manner that the virtual 3D image of the object is reconstructed in the imaging frame when the imaging frame is placed on the display unit and corresponds to the central area in position; determining, by the processor, whether a time duration for which the display unit displays the image parts is not smaller than a predetermined time duration; and when affirmative, adding, by the processor, a learning score to the total score.
