A system projecting information onto a transparent surface in the user’s field of view, allowing individuals to view data without averting their eyes. As an example, consider navigation information appearing on a car’s windshield, enabling drivers to maintain focus on the road ahead.
Such technology enhances situational awareness and reduces cognitive load by presenting vital information unobtrusively. Originally developed for military aviation, its benefits in improved safety and efficiency have led to adoption in various sectors, including automotive, sports, and industrial applications. Its evolution reflects an increasing demand for streamlined information delivery.
