Abstract: A Nine-Grid keyboard with the precise full-Pinyin input of the minimum syllable-oriented, characterized by: it consists of a Nine-Grid main-level keyboard with five additional vowel-finals keys, A, E, U, I and O, and combines the minimum syllable-oriented input sub-keyboards of eight full-mapping levels, and when the conversion conditions of Pinyin syllables are satisfied, the input key is clicked from the keys marked as 2-9 of main-level keyboard, so as to trigger switching to the input sub-keyboard of each mapping level, and any click input of the input sub-keyboard at each mapping level will return to the main-level keyboard, and the precise full-Pinyin input can be realized on the Nine-Grid keyboard through the minimum syllable-oriented and five additional vowel-finals keys. All keyboards of the embodiment of the invention are simplified to a fixed format, and removed the multiple Pinyin syllables prompt scrolling selection bar of the traditional Nine-Grid keyboard; the input complexity of the traditional Nine-Grid is obviously reduced; this new way of input changes “Post-Click Intervention Input” to “Click-and-Predict Input”, and effectively improves input efficiency.
