![]() This strengthens memory, along with repetition and dictation exercises, and gives you plenty of opportunities to practice new material. To help you practice each key, the corresponding letter appears on the screen and is read out loud. Some programs, such as Touch-type Read and Spell, use a multi-sensory technique to reinforce what you learn. They show you where to position your hands on the keyboard and walk you through the right keys to hit with each finger. There are courses designed specifically to teach you typing. ![]() An online typing course can teach basic finger positioning Typing quickly and accurately with correct finger placement involves building up some muscle memory in your hands, so they feel comfortable reaching for keys in sequence and the movements become automatic. ![]() But becoming a pro at typing requires more than just knowing which finger sits on which key.įirst you will need to learn how to reach the keys with the correct fingers and then you’ll have to practice, practice and practice some more. If you liked this post, feel free to follow me on Twitter, or check out any of my other posts.If you are considering learning how to touch-type, then you’re probably aware there is a certain base position in which to rest your fingers so they can reach all of the keys on the keyboard. Instead, looking at an average to above average typist, we can see that their fingers would travel no more than 1.5 miles in a day. We’d have to write all of “A Tale of Two Cities” in a single day for us to hit a total travel distance of 12 miles. Let me know if you’re willing to let me install a key logger on your computer so I can get a more accurate number □. So, it seems reasonable to assume that, in practice, an individual might type 45K lines a day or 120K (15K x 8 hours) lines a day assuming they don’t take any breaks or have any interruptions. On average, English words contain five characters per word hence the 250 strokes / min assumption. This article argues that we all type much less than we think, while providing a nice upper limit for testing. In this characters dictionary, we defining a mapping between characters and the straight line distance to their origin keys on the home row (measured in cm on the Apple Magic Keyboard). So, in order to be accurate, I should only count the distance to and from Shift when the input changes from upper to lower case. You’d naturally press the Shift key at the start of the word COOL and release your finger only at the end when there are no more uppercase characters to type. If you’re using Shift, you’ll encounter a similar problem. So instead of counting a finger’s distance to the key and then the distance back to its origination location, the distance back should only be included if the new character differs from the previous one. It’s likely they’d keep it there and just press the key twice. Typically, a user typing cool wouldn’t bring their finger back to the home row after typing the first o. Additionally, we’d also add the straight line distance returning from t back to f.Īlthough it seemed reasonable at first, I realized we would have to deal with a few more edge cases. In contrast, if they typed t, we would add the straight line distance from the center of the f key to the center of the t key. Taking the image above as an example, if the letter f was typed, no straight line distance would be travelled. ![]() Then, the final typing distance would simply be calculated as the sum of these values. The algorithm would simply measure how far a finger moves from its original location (in centimeters) on the home row. After typing a character, the user will return their finger to the home row unless the character repeats.All measurements involved are based off the Apple Magic Keyboard and I’m estimating the vertical change on a key press to be 1mm.Typists use touch-typing and set their hands in the way shown in the image above.
