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.

Ergonomics also governs the design of alternative computer input devices for people with 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 avoid this, both for those who already have problems and for those who want to avoid getting them, there are split keyboards, curved keyboards, not-really-keyboards keyboards, and other alternative input devices.
