22. The method of claim 21 , wherein the region of effect defines an area in which the spell output is to be applied to the one or more external output devices within the area, and the method further comprises: determining by the computer device, a spell output intensity for the spell output, wherein the spell output intensity is based on a position of the one or more external output devices within the region of effect relative to the wand position and the spell output intensity indicates an intensity at which the one or more internal output devices and the one or more external output device are to be activated: and adjusting by the computer device, the spell output intensity based on the degree of similarity including decreasing the spell output intensity according to the number and order of operations of the spell sequence that match the number and order of operations of the defined spell sequence and based on a distance between the position of the one or more external output devices within the region of effect and the wand position including decreasing the spell output intensity as the distance increases.
