Virtual Reality Games: Extending Unity Learn Games to VR

Research involving virtual reality (VR) has dramatically increased since the introduction of consumer VR systems. In turn, research on VR games has gained popularity within several fields. However, most VR games are closed source, which limits research opportunities. Some VR games are open source, but most of them are either very basic or too complex to be easily used in research. In this paper, we present two source-available VR games developed from freely available Unity Learn games: a kart racing game and a 3D adventure game. Our hope is that other researchers find them easy to use for VR studies, as Unity Technologies developed the games for beginners and has provided tutorials on using them.
