摘要
PURPOSE: A Vietnamese input system by using a shortened type keypad and a method thereof are provided to input effectively Vietnamese by using the limited number of input clusters. CONSTITUTION: An input module(10) is comprised of the first clusters to which a plurality of consonants are allocated, and tones of voice and second clusters to which a plurality of vowels are allocated. A control unit(20) extracts the first scan code corresponding to the input signals inputted through the input module(10). When the first scan code which is extracted is a scan code corresponding to a vowel, the control unit(20) recognizes the second scan code inputted continuously as a tone scan code, and mixes and outputs the first and second scan codes. The control unit(20) includes a scan code extraction module(22) for extracting a scan code corresponding to a signal inputted through the input module(10). A scan code discrimination module(24) discriminates whether the extracted scan code is a scan code corresponding to the vowel inputted from the second cluster. When the scan code discriminating result is a vowel, a tone mixing module(26) mixes and then outputs the tone scan code corresponding to the signal inputted from the first cluster continuously with the extracted scan code. A stack(28) stores temporarily a vowel for mixing with a tone.
