Research On The Morphological Feature Of The Portable Audio Used By Visually Impaired People

According to the survey,for now the market of the portable audio players in china has faced the situation that the high-end market is controlled by foreign well-known enterprises while the low-end market homogenization is serious.Therefore the audio industries in China are in urgent need of improve their brand value through design and technology,they must rely on scientific research,and to explore new design breakthrough by aiming at specific people.On the other hand,the number of the visually impaired people is amazing with the increasing trends in China,and this group has a strong demand of portable audio,while we have kept little attention to this aspect.Besides,for now the designers usually treat disabled people with sympathy,they always want to correct the disfigurement for the disabled people,leading to the final design of the products,although the final product that they design maybe can realize the basic function demand,the potential condescending attitude will bring negative emotion to the visually impaired people.This paper is try to study the characteristic of the portable audio forms for the visually impaired people:First,through the method of sorting secondary data,starting with the portable audio itself,understanding the development of the portable audio;by analyzing and summarizing the data that searching in the web,we will see the pattern of the market;we will carve up the market according to the price,and choose a typical product from each of pattern for specific parameters analysis,to make the foundation for latter market positioning;at the same time,we will investigate the living situation of the visually impaired people,analysis their physiological and psychological characteristics,and analysis the products for visually impaired people,finally get the preference of visually impaired people in form and material.Then using User Centered Design analysis theory as the guidance of the central dogma,which is based on user behavior(Human Factor Analysis System and Norman Behavior Analysis System)and the theory of memory(Memory Theory and Schema Theory)as the theoretical basis for the study of the operation interface for visually impaired people;using Observation and Interview,User Archetypes,Empathy Map and Service Blueprint as research method,and finally according to the background of education the visually impaired people will be divided into "blind school" and "social",we will conclude possible opportunities for each of these two groups.Finally we will extract the key points of design from each chapter,sum up that the basic idea of this design is to avoid the feelings of compassion,try to fully exploit the potential of visually impaired people during the design,enhance their user experience,to create psychological advantage.And we will use these different facilities characteristic elements between two kinds of visually impaired people where in "blind school " and " social " into the project of Suzhou Shangsheng company,then we will get two kinds of portable audio for visually impaired people which are meet the function and reasonable needs.On the one hand,this paper has filled up the lack of the research of portable audio for the visually impaired people,and provided a new direction for the development of portable audio design;on the other hand,presented the theory of "Respect Design" which is providing a new design method for the disabled people.
