♦ When considering the user’s distance from the screen, the following are useful
guidelines:
– The distance from the user’s eyes to the viewing screen should be
approximately the same as the distance from the user’s eyes to the keyboard.
– For most people, the reading distance that is the most comfortable is
approximately 20 inches.
– The workstation surface should have a minimum depth of 36 inches to
accommodate distance adjustment.
– Adjust the screen angle to minimize reflection and glare, and avoid highly
reflective surfaces for the workstation.
♦ Use a well-designed copy holder, adjustable horizontally and vertically, that allows
referenced hard-copy material to be placed at the same viewing distance as the
screen and keyboard.
♦ Keep wires and cables out of the way of users and passersby.
♦ Choose a workstation that has a surface large enough for other tasks and that
provides sufficient legroom for adequate movement.
