Traditional vs. Split Keyboards
Traditional keyboards are not designed with ergonomics in mind. When you type on a traditional keyboard, your arms have to reach in from the sides of your body at an angle. Because traditional keyboards are not angled themselves, this means that your wrists have to then bend out in order to line your hands up with the position of the keys on your keyboard. This unnatural positioning of the wrists has become second nature for many of us, but for many, this awkward typing position can cause discomfort, especially after long typing sessions.
Split keyboards solve this problem by allowing each half of the keyboard to be positioned to better match the natural position of your arms while typing. There are two kinds of split keyboards: unibody and split-body. Unibody keyboards simply split the keys on the keyboard into two groups, and usually angle these keys to align with the angle of your ams while typing. Split-body keyboards have 2 separate halves that can be angled and spread apart to match your specific needs.
