Abstract
A scene depicted using a binocular display device may be mis-calibrated in the vertical axis and generate vertical alignment error. A free-fusion state inducing scene may be first displayed that presents a user of the device with a contrasting scene that allows the user to recognize effects of vertical alignment error. Once accustomed to the free-fusion inducing scene, a vertical alignment error measurement scene may be displayed to the user to determine the vertical alignment error generated due to the miscalibration of the device. Based on the observed vertical alignment error, user input may be obtained to align the two patterns. A correction factor may be determined based on the user input and the device may be calibrated based on the correction factor.
