Learn to type faster

Touch typing

This web application will help you to learn touch typing, which means typing through muscle memory without using your eyesight to find the keys on the keyboard. It can improve your typing speed and accuracy dramatically. The opposite is hunt-and-peck typing, a method of typing in which you look at the keyboard instead of the screen, and use only the index fingers.

The teaching method

This application uses a unique approach. It employs statistics and smart algorithms to automatically create typing lessons that match your current skill level. It works by repeating the following cycle:

  1. The algorithm generates a list of random words for you, based on your typing skills. Your skill level is measured using the typing statistics collected so far. The words consist of a set of letters selected by the algorithm.
  2. You type the given words. You try to make as few mistakes as possible.
  3. As you type, the algorithm collects your typing statistics, such as the time-to-type metric for each individual key. At the end, these statistics are used to generate the next list of words for step one.

At each stage you just type the provided lists of words, and the computer does the rest.

The word generating algorithm

This application generates random but readable and pronounceable words, using the phonetic rules of your native language. These words look almost natural, and often are. Typing sensible text is much easier than repeating random letters, and it helps you remember frequent key combinations. The latest point is crucial. For example, it’s almost impossible for the letter ‘W’ to follow the ‘Z’ in English, and you will never type such a combination in this application. Instead, you will type more common words, such as ‘the’, ‘that’, ‘with’, and so on. Soon you will learn how to type the ‘th’ combo really fast.

The words are generated from the letters which are selected using the following rules.


알고리즘은 알파벳 몇 개에서 시작해요


방금 시작하셨다면 과거 타자 실력을 저희가 몰라서 ‘E’, ‘N’, ‘I’, ‘T’, ‘R’, ‘L’처럼 몇 개의 흔한 알파벳으로 단어 목록을 만들어 드려요. 모든 단어들은 이 알파벳만을 사용해 만들어지고, 나머지 알파벳으로 단어를 만들지 않아요. 쓰이지 않은 알파벳은 기록이 아직 없기 때문에 회색으로 표시돼요.


You learn the initial letters


As you begin to type the generated words, the computer collects your typing statistics. The indicators start to change their colors from red to green. The color red means the typing speed for that individual key is slow, and the color green indicates the opposite. At this stage your goal is to make all the letters green by improving your typing speed. Please note that in this example, letter ‘T’ is highlighted as it has the worst typing speed metric, so it becomes the target letter. The target letter is included in every generated word and this is a crucial piece of information to know. It means that at any given time you are practicing the exact key that gives you the most trouble.


The algorithm adds more letters


When your typing speed improves, and all the letters finally become green, a new letter ‘S’ is added to the set. The random words will be generated from this new expanded set of letters. Letter ‘S’ is the target letter and appears in every generated word. Again, the indicator color of this letter is gray because its typing statistics are unknown.


You learn additional letters


At this step your goal is to make this new letter green, and when this happens, yet another letter is added to the set, and the cycle continues. Realistically speaking, it is very likely that the typing speed of the previous letters will degrade, and you will see that they become red again, as in the example. This is expected, your goal is still the same, to make the new target letter green to unlock the next one.


The cycle repeats


If you are persistent enough, sooner or later all the letters will become green. Congratulations, you have achieved your main goal! However, this does not mean that you should stop learning, you can keep going for as long as you wish.

The precise meaning of each indicator color is given in the following legend.

Indicator color coding.
  • ? A non-calibrated key with an unknown confidence level. You still have not pressed this key yet.
  • ? A calibrated key with the lowest confidence level. The more times you press this key, the more accurate this metric becomes.
  • ? A calibrated key with the highest confidence level. The more times you press this key, the more accurate this metric becomes.
  • ? A key with increased frequency. It takes you the most time to find this key so the algorithm chose it to be included in every generated word.
  • ? A key which was manually included in the lessons.
  • ? A key which was not yet included in the lessons.

The right way to use keyboard

Put all your fingers on the home row, the one containing the Caps Lock key. There are small bumps on the keys ‘F’ and ‘J’, put your index fingers on the bumps. Each finger is responsible for its own set of keys, as explained in the next illustration.
