Dayi (literally "big easy") uses a set of 46 character components laid out on a standard QWERTY keyboard. A Chinese character is built by combining up to four of these characters, using a system not unlike that of Cangjie.
On most keyboards in Taiwan, most keys show four symbols. On the keys, the Latin letters are in the upper left, Zhuyin symbols on the upper right, Cangjie symbols on the lower left, and Dayi symbols on the lower right.
Dayi (literally "big easy") uses a set of 46 character components laid out on a standard QWERTY keyboard.
A Chinese character is built by combining up to four of the 40 of the 46 characters (other six is provided for typing Taiwan address), using a system similar to that of Cangjie, but is decomposed in stroke order instead of in geometric shape in Cangjie.
Unlike other input methods, Dayi's use of 46 character components instead of 26 happens to be its greatest ill, because it makes typing digits and punctuation marks very inconvenient.
