Dayi method

Dayi (Chinese: 大易; pinyin: dàyì, literally "great ease") is a system for entering Chinese characters on a standard QWERTY keyboard using a set of 46 character components.

The keyboard layout for the Dayi input method contains keys for many of the Kangxi radicals in its entirety.

[1] In comparison, in Cangjie, "車" in "輸" (JJOMN) is represented by "JJ" for "十十", thus requiring up to 5 keys per Chinese character.

A user of Cangjie would require experience and attention to decomposition rules to notice that the "田" segments of the Kangxi radical are omitted.

Unlike other input methods, Dayi's use of 46 character components instead of 26 happens to be its greatest impediment, because it makes typing digits and punctuation marks very inconvenient.
