Ergonomics
Ergonomics
(from
Greek ergon work and nomoi natural laws) is the
study of
designing objects to be better adapted to the shape of the
human
body and/or to correct the user's
posture. Common examples include
chairs
designed to prevent the user from sitting in positions that may have a
detrimental effect on the
spine, and the
ergonomic desk which offers an
adjustable keyboard tray, a main desktop of variable height and other
elements which can be changed by the user.
Ergonomics also governs the design
of alternative
computer
input devices for people who want to avoid
repetitive stress injury or
carpal tunnel syndrome. A normal
computer keyboard tends to force users to keep their hands
together and hunch their shoulders. To prevent the injuries, or to
give relief to people who already have symptoms, special split
keyboards, curved keyboards, not-really-keyboards keyboards, and other
alternative input devices exist.
