“…Drivers typically move their head and/or their eyes to a display to bring the fovea or area of highest acuity vision onto the display. The ability of the driver to detect and respond to vehicles or objects on the road ahead when glancing downward is determined by the limits of the human peripheral visual system, more so by the up-down visual dimension rather than the left-right one, as shown in the [9], [10] data, and is well known from human visual periphery studies [20]. These limits are more closely associated with the actual downward angle in the vertical dimension of the driver's eyes, not the 2D side angle in vehicle coordinates.…”

The Alliance of Automotive Manufacturers (Alliance) has produced a document in which Principle 1.4 gives criteria and methods for calculating downvision angles to navigation and telematics displays in vehicles. This paper describes the details of the criteria and methods for determining compliance. Visual displays placed high in the vehicle instrument panel help drivers to use their peripheral vision to monitor the roadway for major developments, even during brief glances to the display. The Alliance has developed two criteria to define the maximum allowable downward viewing angle for displayed information in North American vehicles. One criterion is for use in two-dimensional Computer Aided Design (CAD) analyses, and one is for use in threedimensional CAD analyses. Alliance Principle 1.4 is consistent with known driver performance research data, and known facts about the peripheral sensitivity of the human visual system.
