An ergonomic keyboard is a computer keyboard designed with ergonomic considerations to minimize muscle strain and a host of related problems. Typically such keyboards for two-handed typists are constructed in a V shape, to allow right and left hands to type at a slight angle more natural to the human form.
A "fixed-split keyboard" is a single board, with the keys separated into two or three groups, allowing the user to type at a different angle than the typical straight keyboard.
An "adjustable split keyboard" has the keyboard split into several independent pieces, so the angle between them can be easily changed.
A further development of the split concept are contoured keyboards like the 1977 Maltron or the newer Kinesis Advantage line, which place the keys into two depressions set approximately at shoulder width, with function keys set between the key groups for use with the thumbs. In this configuration, very little movement of arms and wrists is required.
Handheld ergonomic keyboards are designed to be held like a game controller, and can be used as such, instead of laid out flat on top of a table surface. They allow the user the ability to move around a room or to lean back on a chair while also being able to type in front or away from the computer. Some variations of handheld ergonomic keyboards also include a trackball mouse that allow mouse movement and typing included in one handheld device.
Angled split keyboard
The angled split keyboard (sometimes referred to as a Klockenburg keyboard) is similar to a split keyboard, but the middle is tented up so that the index fingers are higher than the little fingers while typing. Key Ovation makes the Goldtouch ergonomic keyboard which is an adjustable angled split keyboard.
Other ergonomic keyboards
Other ergonomic keyboards have fixed, vertically aligned keys, so the user types with their hands perpendicular to the ground, thumbs-up. Still others allow a range of rotation and elevations. A few ergonomic keyboards do not have the typical one key per letter, such as a keyer or a keyless ergonomic keyboard. DataHand eliminates the need for any wrist motion or finger extension.
It is claimed that an ergonomic keyboard may reduce muscle strain and reduce risk of carpal tunnel syndrome or other kinds of repetitive strain injury, but one should be aware that many “ergonomic” keyboards change the musculoskeletal region exposed to risk, instead of eliminating hazardous postures. Manufacturers also claim that after a user takes the time to adjust to this style of keyboard, they can increase typing speed.
Ergonomic keyboards are above the average price of standard keyboards (due to sophisticated manufacturing). You may need some practice to get used to the new layout and typing experience. These keyboards are mostly beneficial for users with the skill of "blind-typing". Without this skill the average user may not find any true benefit, as it feels more complicated than using a standard keyboard.
