Abstract
A head-mounted display device is disclosed, which includes an at least partially see-through display, a processor configured to detect a physical feature, generate an alignment hologram based on the physical feature, determine a view of the alignment hologram based on a default view matrix for a first eye of a user of the head-mounted display device, display the view of the alignment hologram to the first eye of the user on the at least partially see-through display, output an instruction to the user to enter an adjustment input to visually align the alignment hologram with the physical feature, determine a calibrated view matrix based on the default view matrix and the adjustment input, and adjust a view matrix setting of the head-mounted display device based on the calibrated view matrix.
