Abstract

This invention relates to a method for two-keystroke KANJI character input in which the home row of keys plus the keyboard space bar are operative as a ZIPF law coding pad. The method provides instant learning for the novice operator as well as efficiency for the expert typist. Illustratively, suppose a multiple character keyboard organized in rows and having a space bar is invoked. Suppose, two-stroke codes are assigned to a predetermined number of the most frequently occurring KANJI characters constituting, say, 65 percent of the characters in the language. The algorithm includes the following factors: 1. Select n keys from the character-entry keys of a computer-assisted keyboard entry system. 2. Select m other keys from the keyboard. 3. Select the mxn (m times n) most useful ideograms from the language of interest.
