Abstract
The invention shows that words or phrases may be input without ambiguity in some languages and with a little ambiguity in most languages by applying (language restricted) RSM and CVSK. Moreover, this invention proposes an innovative system which recognizes in early stage of input whether an input value is a simple code or a full code by CIM (i.e. Language Restricted CIM) with a language restricted input method as FIM.
