Abstract

The invention discloses a method for writing characters on a touch screen, which relates to a touch screen character writing technology. The method is proposed according to the writing and applicationcharacteristics of a Multi-touch screen and comprises the following steps: transferring a standard character from a character database,; receiving a character to be compared and input by a user; andcomparing each stroke to be compared with each standard stroke so as to obtain a first comparison result and a second comparison result, wherein the standard character consists of standard strokes, the strokes comprise standard structure property values and standard shape property values, the first comparison result shows whether the structure property value to be compared of each stroke to be compared is the same as the standard structure value of the standard stroke or not, and the second comparison result shows whether the shape property value to be compared of each stroke to be compared isthe same as the standard shape property value of the standard stroke or not. The invention also discloses a device for achieving the method. The invention is easy to implement and is particularly sui table for penmanship exercises.

Description

technical field [0001] The invention relates to touch screen character writing technology, in particular to a method and device for writing characters on a touch screen. Background technique [0002] In recent years, touch screens have become popular for their ease of use, robustness, fast response, and space-saving advantages. The application of text writing through the touch screen has also emerged at the historic moment. Since the current touch screen is a single-contact mode, when writing text, it is a line with a constant width. The text matched with the line input by the user is displayed to the user and the user's selection is accepted, thereby completing the input of the text information. [0003] At present, with the continuous development of technology, a multi-touch (Multi-touch) screen technology has emerged, and the Multi-touch screen can simultaneously obtain information from multiple points on the screen. Multi-touch screens are mainly used in the field of m...
