This model is useful for checking that there is comfortable view to a monitor for users in various postures (as defined in ISO Standard 11064-4:2004).
The model includes an indication of the 'Primary Display Zone'* for people in the following defined postures:
A: Bent Forward
B: Sat Erect
*Primary display zone; 40 degrees above and below the Line of Sight (LOS), and 35 degrees left and right of LOS.
Note that the LOS angle and eye position changes for each posture.
There are a set of cones to represent the primary display zone for both 5th percentile females (the purple set) and 95th percentile males (the blue set). #Control_Room #Ergonomics #Human_Factors #Posture #Viewing_Cone #Workstation
