Explain why some computer keyboards have an azerty layout while others have a qwerty layout.

In short (click here for detailed version)

The azerty layout is used in France, while the qwerty layout is more common in English-speaking countries. These choices stem from the historical legacy of early typewriters and the specific linguistic needs of each country.

Historical origins of AZERTY and QWERTY layouts

The QWERTY layout was born in the United States around the end of the 19th century, at a time when the first typewriters were emerging. At that time, the keys of the machines could easily get tangled and jammed when two adjacent letters were typed too quickly. To avoid this problem, inventor Christopher Sholes created the QWERTY layout by spacing out the most commonly used letters in English to slightly slow down typing (yes, slow down, you read that right) and thus reduce jamming.

As for the AZERTY keyboard, it is an adaptation of QWERTY primarily designed for French-speaking users. European manufacturers, particularly the French, wanted a keyboard suited to the French language, altering the placement of several frequent letters like A and Z. This change made it easier to type common words in French, thus giving rise to the famous AZERTY.

Linguistic influences and adaptation to languages

The AZERTY and QWERTY keyboards have evolved differently based on the dominant language in which they were used. Typically, AZERTY fits French better: the most frequent letters like "A," "E," or "Z" are placed in easily accessible positions. In contrast, the QWERTY layout, originally designed for English, prioritizes the placement of letters according to the frequency of English words. The differences logically arise from the specific vocabulary and sounds used in each language. For example, in French, there is direct access to accents on the top keys (é, è, ê, à), while the English keyboard does not really need them. Each language has thus adapted its own keyboard more or less directly to make typing more intuitive and faster.

Industrial standards and adoption by manufacturers

Keyboard manufacturers do not reinvent the wheel in isolation. They follow industry standards that make their lives easier: simplified production, reduced costs, and interchangeability of components. When the Remington typewriter became a commercial success in the late 19th century, its QWERTY keyboard became a spontaneous reference that many other American manufacturers adopted. In France, local manufacturers preferred to gradually adapt the keys to their French-speaking customers: that's how the AZERTY variant became popular. And today, even though it would be technically easy to create more ergonomic layouts, the weight of habit and compatibility with existing devices prevent manufacturers from revolutionizing their designs. As a result, QWERTY and AZERTY have become sort of de facto standards, simply because everyone has become accustomed to them.

Geographical distribution and cultural reasons

If you live in France or Belgium, you probably use an AZERTY keyboard, while in the United States, the United Kingdom, or English-speaking Canada, it's more of a QWERTY. The boundary between these two layouts is mainly cultural and linguistic: we adapt the keyboard to the language we commonly use. For example, the AZERTY keyboard mainly facilitates typical French characters like accents or the famous "é" that often appear in our sentences. In contrast, the QWERTY layout fits well with English, which is generally devoid of those complicated accents. With globalization, some countries adopt the dominant standard, and QWERTY has become the most widespread worldwide. However, some countries like Germany with their QWERTZ keyboard assert their linguistic identity by seriously adapting the keyboard to their specificities. Ultimately, it is as much a cultural reflection as a practical matter.

Effects of different arrangements on effectiveness and learning

The layout of the keyboard directly influences typing speed and comfort, especially over long periods. For example, QWERTY was initially designed to prevent mechanical typewriters from jamming during fast typing, not to maximize efficiency. AZERTY, on the other hand, has certain practical features for writing in French, but it has keys placed in a rather illogical manner, which can slow down learning for beginners. Today, other alternative layouts like Dvorak or BÉPO are being studied and created specifically to reduce finger movement and muscle strain. They thus promise a smoother, faster, and less tiring typing experience, but they require a significant adjustment period to be mastered properly.

Frequently Asked Questions (FAQ)

1

Why are some letters on the keyboard arranged in an apparently random way?

Unlike a common misconception, the initial QWERTY layout was not random: it was designed to prevent mechanical jams in typewriters by spacing out frequently typed letters. This historical constraint led to an apparently irrational distribution, which persists today out of habit.

2

Does the choice of keyboard layout have a real impact on fatigue or user comfort?

Sure! Here's the translation: "Yes, the layout can directly influence accuracy, speed, and the feeling of muscular or joint discomfort during prolonged use. Ergonomic layouts, such as DVORAK, aim to reduce fatigue by limiting finger movements and making better use of hand alternation."

3

Are there other keyboard layouts besides AZERTY and QWERTY?

Yes, there are several other keyboard layouts. Among the most common are QWERTZ, primarily used in German-speaking countries, as well as DVORAK and COLEMAK, which prioritize ergonomic efficiency and typing speed. Each layout has its own advantages depending on usage and linguistic preferences.

4

What keyboard layout optimizes typing speed the most?

Some layouts, such as the DVORAK or COLEMAK layouts, are often cited as more ergonomic and optimized for increasing typing speed by reducing the distance traveled by the fingers. However, learning them requires time and practice; QWERTY and AZERTY remain predominant due to habit and standardization rather than optimal efficiency.

5

Can you easily change the layout of an AZERTY keyboard to QWERTY or vice versa?

Sure! Here’s the translation: "Yes, this is generally possible through the computer's settings. On most modern operating systems (Windows, macOS, or Linux), you can change the software layout of the keyboard independently of the physical keys. However, note that it may be necessary to use stickers or memorize the new layout if your physical keys no longer match."
