Abstract
Abstract An input method including a novel keyboard facilitates entry of Chinese characters into a computer. Character Roots or Radicals are selected in accordance with the first pen-stroke used by Chinese in writing such Root or Radical and those that begin with the same stroke are symbolized on keys in separate selected sections of the keyboard. As a further aid, Roots or Radicals that have the same second pen-stroke are selected and symbolized on specified keys having a secondary identification design or motif. The method includes selecting, in the traditional Chinese order of writing, the first Root to be encoded and, from the keyboard, the key having such Root thereon, the location selection being facilitated as described above, and actuating the key, and continuing to select the second and third Roots in the character and actuating the corresponding keys.
