Abstract
A viewing device comprising a controller, a transparent display and a visual shutter. The controller is configured to determine a color of virtual content to be displayed; determine a background color contrasting the virtual content displayed; determine a display area corresponding to where the virtual content is to be displayed; cause the visual shutter to enable a background to the virtual content to be displayed, the background having the contrasting background color thereby providing a contrasting background to the displayed virtual content (DVC); and to cause the transparent display to display virtual content for overlapping at least one visual object (VO) perceivable through the transparent display at least partially onto the background. The visual shutter is configured to enable the background by operating in a mode wherein at least a portion of the visual shutter is blocked to obstruct the VO in the blocked portion of the visual shutter.
