Design For Reach

How far does the LCD needs to in order for the individual to be able to reach.

Use the link length mannequin and the stature of the individual to find the reach

proportions.

Individual’s Stature is 58.0 inches.

Reach length = 0.186(58in) + 0.146(58in) +0.108(58in) = 25.52

inches.

This means that the LCD can be placed 25.52 inches from the shoulders.
