Keyboard design refers to the layout and arrangement of keys on a keyboard, which can significantly affect typing efficiency and comfort. Common layouts include QWERTY, AZERTY, and Dvorak, each catering to different typing preferences and languages. Ergonomic designs aim to reduce strain on the hands and wrists, often featuring split layouts or adjustable angles. In addition to layout, keyboard design also encompasses key shape, size, and feedback. Mechanical keyboards, for example, use individual switches for each key, providing tactile feedback and durability. Other designs may focus on slim profiles or wireless connectivity, catering to various user needs and preferences.
