Abstract

High-resolution Extended Reality (XR) rendering imposes energy demands. While perceptually driven power optimization methods exploit properties of the human visual system, they assume symmetric visual sensitivity across both eyes. We investigate whether inter-ocular asymmetry in chromatic sensitivity can be leveraged for power reduction. Using 4-Alternative Forced Choice (4AFC) measurements and Radial Basis Function Neural Network modeling (RBFNN), we derived per-eye discrimination maps. These maps were discretized and validated on video content using 2-Alternative Forced Choice evaluation. Results show that the nondominant eye tolerates stronger chromatic reduction without degrading binocular quality, enabling up to 24% power savings.
