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. Supplementary image may be displayed at alternate background location determined according to non-color characteristic of supplementary image. Supplementary image may be displayed according to physical characteristics of HMD display screen.

Abstract: Method and system for enhancing visual perception of augmented reality presentation. The location and line-of-sight (LOS) of a user wearing a see-through head-mounted display (HMD) is detected. A future background environment to be viewed by the user through the HMD is predicted based on at least the detected location and detected LOS. At least one color-attribute of the future background environment at a background location corresponding to a user LOS is predicted. The predicted color-attribute is compared with at least one color-attribute of an intended foreground supplementary image to be projected on the HMD overlaid onto the future background environment at the background location. When an incompatibility condition is detected, at least one visual parameter of the supplementary image is adjusted to minimize the incompatibility condition, and the supplementary image is projected on the HMD at the background location with the adjusted visual parameter.
