Graphics is an important and effective form of visual symbols，and it has an important meaning for spreading information. Graphics are composed of two parts：picture and form，which are artificial and functional. Compared with other media such as text，graphics are more functional and can truly spread a certain concept or image content.①Sign language is an intuitive and natural way of visual communication. It recognizes the content to be conveyed by gestures in accordance with specific rules. It has strong consistency and expandability. At the same time，graphics are a visual symbol language with descriptive functions. The two have an inseparable relationship.

The graphic design and research of sign language refers to the presentation of sign language in a functional form of visual graphics，and a new interpretation of sign language graphic design. ②In the specific implementation process of this design，what kind of visual symbol，what kind of visual expression and what design method can most directly and effectively convey the visual information of sign language are the core issues of the research of this thesis. The sign language graphic design adopts Visual graphic representations，based on the study of previous materials and literature，can conclude that there are three rigorous and objective ways to convey visual information in graphic design，namely：simulation，understanding and symbolism. The simulation method is the most basic visual expression method in the graphic design method，and its application is also the most widely used. Knowing method refers to the graphic design method based on the design of simulation method，in other words，it is the graphic design method based on the external image of basic objective things that can be interpreted by people. It re-integrates，interweaves or deforms，and derives two or more graphics with typical external characteristics of visual information. Symbolism is the most complex and diverse of the three graphic design methods. Refers to the more abstract method in graphic design.

Based on the accumulation and provision of the concrete graphic elements of hand gestures in the early stage，the graphic transformation of the following sign language gestures has begun. The process of transformation is a simplified induction of the hand shape，using simple and flat vector lines to illustrate the gestures. ③Eliminate unnecessary hand-shaped details，make it simple but not simple，while highlighting visual impact. The sign language language that needs to be graphically extracted is based on the icons in the "Chinese Sign Language" explanatory dictionary reference book. Simplify，refine and integrate according to the concrete hand gestures，use simple and intuitive points，lines and planes to form a graphic language to express，and draw the simplified and integrated hand shapes in the software by means of vector diagrams.

The research and design of this thesis is the interpretation of the related concepts of sign language and graphics. The previous analysis on the frequency of sign language use by deaf and hearing people is completed. Finally，the method of sign language graphics is constructed based on the specific theoretical methods of graphic design. Analysis and research summarize the visual graphic language of sign language gestures and vocabulary，carry out element extraction，analysis，visual transformation，integration，redesign，and complete the design draft of the sign language visual image. This design has certain research and practical significance. The overall design of sign language graphics is carried out through visual graphics with strong image impact and modern sense. To attract everyone's interest in sign language recognition and learning. In this way，it can achieve sign language reading while meeting the needs of perceiving graphics，arouse social care for the disadvantaged groups，and build a sign language communication bridge between deaf-mute people and hearing people.
