The distance between the keys should be between 18 and 20 mm

(ISO 9241).The alphanumeric keys of the keyboard have to be

separate from the function keys (ISO 9241).Dark keys on a light color

background make reading easier and increase productivity (Snyder,

1990).The middle row of the keys may not be higher than 30 mm,

measured from the desk (DIN 2137). The keyboard should have the

ability to tilt and be separate from the screen so as to allow the

worker to find a comfortable working position avoiding fatigue in the

arms or hands. (Council Directive 90/270/EEC).
