characters into computers.
A set of 37 Chinese phonetic and 5 intonational symbols are used to input the

and 8 special alphabets, is used to input the simplified Chinese characters. The
user keys in the appropriate Pinyin alphabets to bring up a menu of homonyms
on the display, then selects the desired Chinese character by typing its sequence
number on the menu. At the maximum, 8 keystrokes uniquely specify a
simplified Chinese character.
Once input to the computer, the keystroke information is mapped into the
internal character representation code for further processing.
