Beyond Human: Animals as an Escape from Stereotype Avatars in Virtual Reality Games
This work addresses the design of VR games for players by showing that nonhuman avatars can increase enjoyment, though it is incremental in exploring avatar morphology.
The study explored the use of nonhumanoid animal avatars (e.g., scorpion, rhino, bird) in virtual reality games to enhance virtual body ownership and game enjoyment, finding a correlation between these factors and deriving design implications.
Virtual reality setups are particularly suited to create a tight bond between players and their avatars up to a degree where we start perceiving the virtual representation as our own body. We hypothesize that such an illusion of virtual body ownership (IVBO) has a particularly high, yet overlooked potential for nonhumanoid avatars. To validate our claim, we use the example of three very different creatures---a scorpion, a rhino, and a bird---to explore possible avatar controls and game mechanics based on specific animal abilities. A quantitative evaluation underpins the high game enjoyment arising from embodying such nonhuman morphologies, including additional body parts and obtaining respective superhuman skills, which allows us to derive a set of novel design implications. Furthermore, the experiment reveals a correlation between IVBO and game enjoyment, which is a further indication that nonhumanoid creatures offer a meaningful design space for VR games worth further investigation.
