Introduction
-The MXR contrast perception tool measures the contrast sensitivity of human participants on a virtual or augmented reality (VR or AR) head-mounted display (HMD). Contrast sensitivity response (CSR), as the reciprocal of the threshold (minimum detectable) contrast of the human participant, is measured at various spatial frequencies. This is achieved using a 2D sinusoidal pattern with predefined contrast and spatial frequency, known as a Gabor target. The Gabor target can be rendered at a single or 9 locations across the display field of view (FOV) as illustrated below.
