Description

technical field [0001] The invention relates to the field of hand-held device input, in particular to a variable display keyboard and an input method. Background technique [0002] With the advent of the 3G era, various applications on handheld devices are becoming more and more abundant. Various handheld devices not only have the functions of calling / schedule management / browsing, but also have more interactive applications that require users to input a large amount of text, such as mobile office, Mobile Blog and Mobile Mail and more. In the existing input methods of handheld devices, the input device cannot simultaneously achieve high standards of "efficiency", "ease of use", and "fault tolerance", so as to meet the use requirements of a large amount of text input. [0003] At present, the handheld products listed in China mainly need to input content in English and Chinese. Among them, in terms of input forms, Chinese usually has two input methods, pinyin and strokes. T...
