Pen calligraphy expression method based on force information

Abstract

The invention discloses a pen calligraphy expression method based on force information, wherein a three-dimensional force sensor is used for acquiring vector information of a three-dimensional handwriting force generated through the contact between a pen nib and a signature plane. In a pen handwriting process, the three-dimensional force sensor can be used for sensing and outputting information change of three-dimensional handwriting dynamic force acted on the three-dimensional force sensor in real time; a pen contact region generated through the contact between the pen nib and a paper plane is calculated through acquiring and converting the information; and operation and process are carried out on the pen contact region according to the force information, so that a pen calligraphy expression effect under the force information is achieved. The pen calligraphy expression method based on the force information comprises the following steps of: initializing the three-dimensional force sensor so as to obtain three-dimensional handwriting force data and three-dimensional handwriting force information numerical values; carrying out preprocessing calculation; and calculating the pen contact region. According to the pen calligraphy expression method based on force information, disclosed by the invention, a writer can really experience a pen calligraphy expression difference caused by different handwriting forces, so that a new technical measure for pen character creation and calligraphy training on a computer or pen calligraphy correction is provided.

Description

technical field [0001] The invention relates to the field of computer information and automation electronics, in particular to a pen calligraphy expression method based on force information. Background technique [0002] As a writing tool for Chinese characters, the fountain pen has the advantages of small size, easy to carry, convenient to write, durable, and the written characters are not easy to fade. From an aesthetic point of view, although the line expression and artistic appeal of fountain pen calligraphy are not as rich as those of brush calligraphy, they are far better than other hard pens such as pencils and ballpoint pens. severity. A beautiful pen writing can also give people a beautiful enjoyment. Especially in recent years, with the popularization and improvement of pen calligraphy teaching, the majority of pen calligraphy educators and enthusiasts have carried out beneficial exploration and research on the pen calligraphy, structure, composition and calligra...
