Abstract: A device for determining relative orientation between two locations including an imager, an inertial-orientation-sensor firmly attached to the imager for determining information relating to the orientation thereof and which exhibits drift and a processor coupled with the imager and with the inertial-orientation-sensor. The processor determines a first orientation-measurement and first time-tag when the device is oriented with a first-orientation-indicator located at a first location. The processor determines a second-orientation-measurement and second time-tag when the device is oriented with a second-orientation-indicator located at a second location. The processor determines a third-orientation-measurement and third time-tag when the device is oriented again with the first-orientation-indicator. The processor determines the drift associated the inertial-orientation-sensor according to difference between the first-orientation-measurement and the third-orientation-measurement the respective time-tags associated therewith. The processor determines an angle-difference between the first-orientation-indicator and the second-orientation-indicator according to the first-orientation-measurement and the second-orientation-measurement, the first and second time-tags and the drift.

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.
