Dartmouth Digital Commons: Tarsier Goggles: a virtual reality tool for experiencing the optics of a dark-adapted primate visual system . “Tarsier Goggles is a virtual reality (VR) project that allows everyone to experience how a tarsier might see. It serves as a tool to engage in hands-on scientific concepts in optics, perceptual science, and evolutionary biology, and also challenges our own thinking about our environment. The experience is self-guided and allows users to toggle between human and tarsier in order to explore different realistic environments with both sets of eyes. Built in Unity3D with SteamVR for the HTC Vive Pro. For various functionalities like teleportation, splash screens, and tooltips for our tutorial, we use Virtual Reality Toolkit (VRTK), an open source library.” Tarsiers are those primates with enormous eyes. MNN has a good overview.
