Abstract: A system for implementing the sliding input of a text based upon an on-screen soft keyboard on an electronic equipment is provided. The system comprises a feature lexicon module, a feature lexicon establishment module, a user interface module, a sliding trajectory feature extraction module, a rough classifying and filtering module, a rough matching and filtering module and an accurate matching and sorting module. A method for implementing the sliding input using the system is also provided. The system and the method can input a word according to the preorder trajectory of the input portion, and cleverly use a forecasting-between-slidings input, decrease a sliding distance, effectively improve the input speed and accuracy of words, and simplify the operation for the users.
