The aim of the paper is to develop the concept of perceptual relation and to apply it to digital environments. First, the meaning of perceptual relation is phenomenologically analyzed and defined as the interaction between the whole and its parts, which is theorized by the founders of Gestalt psychology. However, this relation is not considered as an intrinsic, but as an extended one, implying also the relation with the surrounding world (Umwelt). Subsequently, this concept of extended relation is applied to a chosen object (a ball) as it is perceived in four different kinds of digital dimensions (on-screen, virtual, augmented, and hybrid). Through a phenomenological analysis, I argue that, whereas the whole-part configuration remains the same, some modes of appearance of the object (multisensoriality, figure-ground interaction, affordances, and persistence) are different. In order to define this dynamic, I have coined the concept of transdimensional analogy.
