Abstract: Manuscript input data processing device including a controlling terminal and a controlled terminal. The controlling terminal includes a display section, an input section and a pen unit. The controlled terminal includes a word selection unit, a memory, a display/control unit and a word operation unit. The controlling terminal has functions of control and display, while the controlled terminal has functions of memory, selection and display. The pen unit is used to touch and sequentially write on the input section the word stroke sequence and corresponding position shown in the word display unit by way of special notation. The display/control unit will record the word track written by the pen unit into the memory. At the same time, the data are output to the corresponding position in the word display unit. After the user completes the correct writing of the word stroke sequence, another word can be selected and automatically displayed. Alternatively, the same word can be used for further practice.
