A toolset was developed for characterizing and correcting spatial misalignment in head-mounted displays.A hardware system consisting of two cameras and various rotation and translation stages was used to emulate the ocular position of most human observers.A checkerboard pattern was displayed on the HMDs and matched to a reference pattern through an image registration process.The HMD image registration process is carried out after the effects of camera distortion and keystone effect are removed.The registration process is repeatable with a standard
