Superception – Expanding human perception with personal projection mapping

Created by Shunichi Kasahara in collaboration with Satoru Higa, Takuto Usami, Shotaro Hirata and Tetsuya Konishi, "Superception" (Super + perception) is a research framework that uses computer technologies to intervene and transform human perception. One of these research projects, “HeadLight" is a system that allows humans to experience the perceptual world of nonhuman species through personal projection mapping.

HeadLight consists of a laser source small project with a wide conversion lens, a headphone and a pose tracker. HeadLight has a fish-eye conversion lens on the projector which enables much wider projection image. However, the conversion lens produces strong distortion in the projected image with pincushion shape. The Headlight system compensates this distortion based on a fisheye model distortion. Therefore, it enables wide-angle visual projection from the point of view of user up to 131 degrees in diagonal angle, minimum approx. 105 deg. horizontal and 55 deg. vertical, which covers a large field of view of human.
