An object is held in any one of a plurality of specific orientations to present an aspect, corresponding to a specific orientation, to an imaging module of an electronic device. An image of the aspect is captured. The current captured image is compared with images in a library of image-command associations to find a match. If a match is found, the electronic device triggers a command execution of the matching image-command association. If no match is found, a new image-command association is established and stored in the library of the image-command associations.
