A user interface method and apparatus which allow a user to intuitively control electronic devices connected to a home network by using a virtual 3D space layout diagram, and electronic devices and storage media therefor are provided. The user interface method includes: generating a virtual 3D space layout diagram based on 3D position information regarding at least one electronic device connected to a home network; displaying the generated virtual 3D space layout diagram; receiving an input signal based on the displayed virtual 3D space layout diagram; and performing a user interface function corresponding to the received input signal.
