1. A non-transitory computer-readable recording medium recording an information processing program, which when executed by a computer, causes the computer to perform operations comprising: storing, in a memory accessible by the computer, a plurality of associations between a feature and a plurality of aspects of a virtual object; acquiring an image of a real space captured by an imaging device; detecting the feature from the image of the real space; counting, based on the detecting, a number of times of detection of the feature for which it is determined that an elapsed time from last-time detection of the feature is equal to or more than a non-zero first threshold; changing a first aspect of the virtual object, determined based on a first association from the stored plurality of associations, to a second aspect of the virtual object, determined based on a second association from the stored plurality of associations, the virtual object placed in a virtual space on a basis of the feature when the feature is detected again after an elapsed time from last-time detection of the feature is equal to or more than a non-zero first threshold; generating an image of the virtual space in which the virtual object in the second aspect is placed on a basis of the feature; and displaying an image on a display device such that the image of the virtual space is superimposed on an image of the real space.
