Database of virtual objects to be used in psychological research

Although many visual stimulus databases exist, to our knowledge, none includes 3D virtual objects, that can directly be used in virtual reality (VR). We present 121 objects that have been developed for scientific purposes. The objects were built in Maya, and their textures were created in Substance Painter. Then, the objects were exported to an FBX and OBJ format and rendered online using the Unreal Engine 4 application. Our goal was to develop the first set of high-quality virtual objects with standardized names, familiarity, and visual complexity. The objects were normed based on the input of 83 participants. This set of stimuli was created for use in VR settings and will facilitate research using VR methodology, which is increasingly employed in psychological research.
