Typing at the speed of thought without looking down, from finger placement to designing input methods.
Typing is what moves the sentence in your head onto the screen without losing any of it. It starts with learning where your fingers rest. From there it runs through typing without looking, then the speed and accuracy real work demands. Next comes the stamina to hold both through long sessions, and a setup tuned for symbols and shortcuts. Higher up, you go past your own speed and start designing how other people type and contributing to input methods themselves.
Develops a standardized copy-typing task across 1,682 participants and reports speed distributions by language and keyboard layout, plus non-linear change with age. Measured basis for where each level draws its speed and accuracy band.
Analyzes 136.9 million keystrokes from 168,960 participants, reporting a mean of 51.56 WPM (SD 20.2), roughly 78 WPM and above for the top 10%, under 26 WPM for the bottom 10%, and a mean uncorrected error rate of 1.167%. Measured basis for the speed and accuracy bands at each level.
Defines the standard learning order: finger positions, then words, then short passages, then long passages. The most widely used typing curriculum in Korea and the authority behind the learning path at the beginner and intermediate levels.
Directs the user to adjust chair and work surface height for a neutral body posture, keep elbows about the same height as the keyboard and close to the body, and raise or lower the keyboard feet to hold straight, neutral wrists. Grounds the Lv.1 posture item and the Lv.4 ergonomic setup item.
