2. Characteristics of Game Transfer Phenomena in Location-Based Augmented Reality Games

This chapter explores sensory perceptions, cognitive mix-ups and slips of actions associated with augmented reality (AR) technologies, such as in location-based AR games. The research on Game Transfer Phenomena (GTP) has demonstrated that playing video games in AR and non-AR can induce sensory perceptions, manifesting as seeing images overlaying physical objects (e.g., seeing power bars above people’s heads or maps in the corner of the eye), hearing sounds coming from game-related objects, and perceiving physical objects as distorted or having misperceptions (e.g., confusing birds with aeroplanes). The aim of this chapter is twofold. The first is to provide an overview of the GTP research conducted on location-based AR games. The second is to highlight the peculiarities of GTP in AR games. While a broad variety of the GTP reported in non-AR games has also been found in location-based AR games, the key characteristic of these games is that the gameplay occurs through interactions in the physical context. The physical context is part of the game by means of (i) the overlaying of game images on the physical context and (ii) the game being played through interactions in the physical context. The key peculiarities of GTP in these games are (i) the temporal manifestation of GTP while/after playing, (ii) the two-way transfer of effects from the virtual to the physical and vice versa, (iii) the increased chances of the occurrence of certain forms of GTP (e.g., the urge to do something related to the game, misperceptions of physical stimuli, tactile sensations) including cognitive mix-ups and slips of actions when confusing virtual objects with real objects and (iv) the GTP triggered by the outputs from a multipurpose device.
