What is in the plan view for BDM Closest Viewer includes the image width, horizontal
viewing angles, closest viewer, and farthest viewer. Elevation view with max eye height to top
of screen maximum 30 degrees.



Practical percent element height range 2% to 4%



Element Height Formula EH = FV / 200, EH is element height, FV is furthest viewer,



ADM Image Height Formula IH = (IR x FV) / 3438


Where:
IH is the image height
IR is the vertical image resolution
FV is the farthest viewer distance
3438 is the acuity factor for ADM (20/20 Vision)



ADM Farthest Viewer Formula FV = (IH / IR) x 3438
Where:


FV is the farthest viewer distance


IR is the vertical image resolution


IH is the image height


3438 is the acuity factor for ADM

, BDM Image Height Formula H = FV / (200 x %EH)
Where:


IH is the minimum image height for the space


FV is the farthest distance a viewer will be from the image


%EH is the percent element height, which is the height of the element being viewed expressed
as a percentage of overall image height


200 is the acuity factor for Basic Decision Making


Note that the display shall have sufficient resolution to render an element at its smallest
prescribed size.


Farthest Viewer Distance shall be determined either by physical measurement in an existing
space or from the architectural layouts.



Percent Element Height, BDM %EH = FV / (IH x 200)
Where:


%EH is the Percent Element Height


FV is the Farthest Viewer Distance


IH is the Image Height
