Microsoft has designed and sold a variety of ergonomic keyboards for computers. The oldest is the Microsoft Natural Keyboard, released in 1994, the company's first computer keyboard. The newest models are the Sculpt Ergonomic Keyboard (2013), the Surface Ergonomic Keyboard (2016), and the Microsoft Ergonomic Keyboard (2019). In general, ergonomic keyboards are designed to keep the user's arms and wrists in a near-neutral position, which means the slant angle (the lateral rotation angle for the keys in each half relative to the axis of the home row in a conventional keyboard) is approximately 10 to 12.5°, the slope (the angle of the keytop surfaces starting from the front edge closer to the user towards the top of the keyboard, relative to a horizontal plane) is -7.5°, and the tent or gable angle of each half (the angle of the keytops from the center of the keyboard towards its left and right edges, relative to the horizontal desk surface) is 20 to 30°. Notes The first generation of the Microsoft ergonomic keyboards, named the Natural Keyboard, was released in September 1994, designed for Microsoft Windows 95 and Novell Netware. It was designed for Microsoft by Ziba Design with assistance and manufacturing by Key Tronic. The Microswitch division of Honeywell, which was responsible for that company's keyboards and was acquired by Key Tronic in early 1994, is also credited with design input. The keyboard uses a fixed-split design, with each half of the alphanumeric section separated, laterally rotated, and tilted upwards and down from the center of the keyboard. This key arrangement was ergonomically designed to prevent carpal tunnel syndrome and other repetitive strain injuries associated with typing for long periods of time. Another innovation was the integrated wrist pad helping to ensure correct posture while sitting at the computer and further reducing strain on the neck, arms and wrists. This keyboard also introduced three new keys purposed for Microsoft's upcoming operating system: two Windows logo keys () between the and keys on each side, and a key between the right Windows and Ctrl keys.
