DOCUMENT HOLDERS

Document holders are used to hold copy material and position it for the task. The copy should be at a distance from the eyes so the material can be comfortably read. Holders reduce the amount of neck bending and twisting caused by prolonged viewing of documents placed on the desk beside the keyboard.
The best location for the holder depends on the nature of document, the weight of the document, the typist's skill, whether the original document needs to be annotated as information is entered, etc.
ANGLE BOARDS

Angle boards are placed on desks to allow the angle of the work surface to be adjusted. They allow the neck to be in a more upright posture while reading and writing for prolong periods. These boards perform a similar function to a draftsperson's drawing board. As these boards can take up a large amount of desk space they are generally only recommended for people who spend long periods of time reading and/or writing.
KEYBOARDS

Research suggests that the "ergonomic" keyboards (split keyboards with each hand at a different angle) are more comfortable to use than standard keyboards. This is because the wrist stays in a natural line rather than having to be bent toward the little finger. However, some people find the extra width makes the position of the mouse worse. If the number pad is not often used, consider keyboards without a number pad. These allow the mouse to be brought closer to the centre line of the body.
