Typing Coach

This web typing application will help you to learn touch typing which means typing through muscle memory without using your eyesight to find the keys. 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.

This application uses a sophisticated computer algorithm to generate typing lessons that match your skill level. These lessons consist of random words generated using a subset of the full alphabet of letters. The size of the subset and individual letter frequency is controlled by the algorithm, which provides you with the best learning experience.

Initially it starts generating words from a small subset of the most frequent letters in the alphabet.

When you are typing these words, the application measures the time-to-type metric for every letter in that subset. This time is used to measure your learning progress. The more familiar you become with a letter, the less time it takes for you to type it.

Once you familiarize yourself with the entire current subset of letters, the algorithm expands it by adding more and more letters to the subset.

When the algorithm includes a new letter to the current subset, the frequency of this letter is artificially boosted so that it will be included in every generated word of a lesson.

The algorithm can also artificially rearrange letter frequencies, placing an emphasis on the letters with the worst time-to-type metric.

This means you will always be typing the letters that you are least familiar with.

This virtual keyboard. It helps you memorize key positions. Use it to find the keys and try not to look at your physical keyboard. There are small bumps on the F and J keys of your keyboard. Use these to correctly position your index fingers without having to look at the keys. Once your index fingers are in the right position you will be able to locate the remainder of the keys. For each Key you will notice a small number represent your confidence with that Key.

Typing speed is measured in either Words per Minute (WPM) or Characters per Minute (CPM). The definition of a word is standardized to be five characters, so 10WPM is equal to 50CPM.

This is the accuracy indicator is computed as the percentage of characters typed without errors. Many typos in the same position count as 25% point error.

The Level is calculated from your typing speed, error count, and the current size of the letter set. The formula is designed to reward for typing speed, and punish for error count. You cannot obtain a high score by typing fast while also making many errors.
