A Study of Blind People based on Morphological Recognition Color - Graphic Research

Objective: This paper puts forward a way that is most helpful to blind people"s touch and reading of graphic color, and improves the situation that the blind people can"t see the color in the daily life of "seeing" art exhibition, which increases the field of color in the blind people"s lives and helps the blind people to study art creation in the future. ① Understand the infinite charm brought by color and improve self-worth ② Broaden the employment scope of the blind ③ Benificial to enrich the spiritual and cultural life of the visually impaired, provides an effective demonstration for the blind to quickly read the application field of graphic color, which is the basis for the future study of dynamic graphic color.Background: Blind people have problems such as "travel difficulty", "image recognition difficulty", "color recognition difficulty" in their lives (Meng et al., 2017). They cannot appreciate the color elements in paintings and use complex colors for artistic creation. They can only rely on the sense of touch, hearing and smell for sensory compensation because of the visual impairment. When they face such information as colorful graphics and images, there is always a lack of effective information acquisition methods. The traditional method is to obtain the rough shape or the voice description image through the tactile image; the blind volunteers also play a vital role in helping the blind to understand the analysis and describe it to the other party through the form of voice; secondly, the blind electronic assistant device can scan and understand its image and color through advanced recognition technology, then describe it in the form of voice (Huiying et al., 2014). However, the artificial description of color can not exclude the understanding of certain human consciousness and it can not convey color or graphic information without damage as well; the electronic assistant device for the blind is too modular and lack of imagination; most importantly, color images replace in a high speed in the Internet era, artificial help and paper tactile images can not carry tactile color or image information in real-time. Method: Firstly, the basic problem is understood through the user interview method. Secondly, the existing blind people"s method of touching and reading color is used to determine the problem. Through the observation of the blind people"s daily study life, the range of graphics that the blind people often touche is determined. Finally, the touch pattern is determined by the touch test.Results: Through the extraction of blind people"s daily learning and life of the commonly used graphics for induction. Secondly, setting the size and arrange the figure according to the Braille international standard and make a 3D model according to the set size and arrangement. Finally, according to the experimental model, we can test it in the specific population of the blind and get the figure that can make the blind touch and read quickly.Conclusion: The choice, size, and arrangement of graphics are the key factors for blind people to read and touch graphics. It is the result of different tests.Application: Focusing on blind users, the use of graphic shapes instead of color can be applied to blind exhibitions, blind teaching, blind art creation, blind film, blind social sharing, etc. We hope to help blind people open up new areas of reading through future research projects.
