A stroke learning and correcting method and system. The stroke learning and correcting method comprises the steps of: S11, detecting in real time whether a Chinese character which a user has selected to practice has been received, and if yes, moving on to step S12; S12, acquiring the strokes of the Chinese character currently being written; and S13, determining whether the strokes of the Chinese character currently being written are correct, and if not, automatically displaying the correct strokes. When writing a Chinese character, a user can promptly learn whether the strokes currently being writing are correct, thus visually and conveniently learning stroke mistakes, and improving the practice effect and writing skills of Chinese characters.
A: Disclosed are a Chinese character simple stroke input method and a Chinese character simple stroke search method. Chinese character strokes are divided into several simple strokes without a salient point, and simple stroke feature information of a Chinese character is formed by the total number of the simple strokes, stroke types of the simple strokes, the stroke type of the simple strokes at a specific part, and the stroke number of different types of simple strokes. A correspondence is established between the simple stroke feature information and a corresponding input component on an input device, to implement input of Chinese characters. A Chinese character database is established according to the simple stroke feature information, thereby implementing search of Chinese characters. The present invention simplifies complex Chinese strokes, so that when inputting Chinese characters, a user does not need to memorize much basic knowledge such as complex rules, keyboard code correspondences and character roots, and therefore, people from both China and other countries can easily grasp the method. In addition, as the user may input the simple stroke feature information of the Chinese character in any sequence and combination, the operation is simple and convenient.
B: A writing scoring system determination method, a system and an apparatus, the method comprising the following steps: S1: acquiring an external writing action; S2: according to the writing action, calculating a writing path; S3: displaying the writing path; S4: deciding whether a completed writing action has been received, and if so, performing scoring according to the writing path; if not, returning to S1. In the present writing scoring system determination method, system and apparatus, a means of deciding that writing is complete has been changed from a time-based determination mode to an action-based determination mode, decreasing human-machine interaction time and improving user experience; using a specified action for completion determination prevents wrong operations such as a system responding early because writing was too slow.
C: Disclosed is a multi-character continuous handwriting input method. A character is written on a touch unit; after character number i is written, character number i+1 is written overlappingly over character number i. When a user is writing, a determination is made whether the current stroke belongs to character number i or to character number i+1. When the user is determined to have started writing overlappingly character number i+1, the display color of character number i is dimmed automatically; this facilitates clear tracking by the user on a display screen of the self-written strokes of the new character. In the method, multiple characters are written continuously without pauses; when character number i+2 is being written, character number i disappears automatically from the display screen, and the color of character i+1 is dimmed automatically. The present invention obviates the need for the user to pause before writing a different character, and allows for the continuous writing of multiple handwritten characters on a handwriting screen, and for the corresponding recognition and display processes, thereby improving greatly the efficiency of handwritten text input.
D: An encryption and decryption method for a terminal and a terminal. The method comprises: collecting the handwriting input information inputted when a user performs the encryption, and storing the handwriting input information as an encryption password, wherein the handwriting input information includes inputted Chinese characters, stroke order of the inputted Chinese characters, and handwriting style characteristics; collecting the handwriting input information inputted when the user performs the unlocking, and determining whether the handwriting input information inputted when the user performs the unlocking is consistent with the encryption password or not, and if yes, the unlocking succeeds, or otherwise the unlocking fails. The above technical solution combines three handwriting recognition modes of the inputted Chinese characters, the stroke order of the inputted Chinese characters, and the handwriting characteristics so as to determine whether the password is correct or not, and the technical solution has the greater security than the related techniques such as unlocking pin codes and unlocking patterns, can protect the private information of the user better, and improve the reliability of the terminal encryption.
