HUMAN-CENTRIC DESIGN & IMAGES/DISPLAYS

According to foundational principles as defined by humanfactorsengineeringergonomics.com, ([2025]), "[t]here are three aspects to visibility. The first is image clarity, which was considered earlier. Image clarity is perhaps the most germane to photographic and computer-projected images. The second aspect of visibility is the location of the display within the operator's field of vision...that the normal line of sight is not directly horizontal from the viewer, but is oriented at a 15° angle downward slope"...wherein "[t]he optimal orientation" of a design output could be suggested as human-centric implentations considering how the central versus peripheral locations of displays ranging between the angles of 30° to 45° determine the most adaptable "line[s] of vision" for intended perspective development and subsequent action(s)/non-action(s) emergence (Guastello, 2014).
