Abstract: Method and system for enhancing visual perception of augmented reality presentation. Location and line-of-sight (LOS) of user wearing see-through head-mounted display (HMD) is detected. A background environment viewed through HMD is determined based on detected location and LOS. Color-attribute(s) of background environment at background location corresponding to user LOS is determined and compared with color-attribute(s) of foreground supplementary image to be displayed on HMD overlaid onto background environment at background location. When an incompatibility condition is detected, visual parameter(s) of supplementary image is adjusted to minimize incompatibility. Color-attribute determination may use information obtained from users previously at background environment, and may be based on user perception resulting from interactions of: geographic location, time when background environment viewed, and user LOS.
