Screen captures from each VRLE in Tarsier Goggles. Paired images simulate the vision of humans (left) and tarsiers (right) under identical twilight conditions, revealing differences in visual sensitivity (brightness), acuity, and color discrimination. a, b VR environment where users can elect to receive guidance. c, d The “Matrix” VRLE contains a lattice of beams that is intended to emphasize human-tarsier differences in visual acuity and color vision. e, f The “Labyrinth” VRLE is intended to emphasize human-tarsier differences in visual sensitivity by challenging users to navigate a dark (scotopic) environment. g, h The “Bornean Rainforest” VRLE enables naturalistic exploration within the understory of a lowland dipterocarp forest
