Abstract : Stereo and bi-ocular head-mounted displays (HMDs) require the user to fuse two images into a coherent picture of the three- dimensional world. The human visual system performs this task constantly but when the input images contain both real and graphical depictions, the problem becomes more difficult. A vertical disparity in the graphics causes diplopia for users flying to fuse the real and virtual objects simultaneously. We implement three methods to measure and collect this disparity and assess them with a collection of a single model of optical see-through HMD.
