The Interface Design Research For Visually Impaired Users APP

3G,socialization,video,network telephone and mobile device have become almost the main stream in modern society.The mobile internet market's design level to the relevant production is raising day by day at home and abroad.Following with the advent of Internet Plus era,the way of information design changes day by day and brings more fresh technical experience to users.An “Internet Plus App” era has coming.People's lifestyle and entertainment was influenced by kinds of applications.The application experience design brings both convenience and new challenges to people.Since Information Accessibility Research Association proposed that “To expand the boundaries of human and Internet connection”,a series of accessibility production for visually impaired population entered into market and the mobile device for this population has becoming the main stream.According to < The basic situation report of Chinese Internet users with visual impairment>,92% of the 220 visual impaired respondents use smartphone and 22% of them use taxi booking Apps.The mobile Apps is slowly approaching the special population.But there is no App interface template for visually impaired population in today's market.There is no set of standard design principles as a reference for the relevant roles such as UI designer,product manager and programmer.Although the accessible mobile phone interface are published in the market,it is only the implementation of hardware and software,and there is still lack of interface design aesthetics,interaction and emotional experience design.It is a big bug for the visually impaired population in the aspect of controllability design.This paper takes these problems as starting point.It introduces the design theory of information accessibility firstly and then simply discuss the development of today's Appinterface for visually impaired users.Finding a breakthrough from existing research and direction.Research on the visually impaired users and explore the interface functions,interaction and emotional experience,then summarize the information design principle of App interface for visually impaired users.On this basis,this paper adopts the research methods of literature review,interview,observation,questionnaire,etc.Then clearly analysis the visually impaired users' lifestyle,physical and mental state and the way of perceiving the world.On this way,the requirement of App interface design for visually impaired users will be explored.Finally the information will be layered in aspect of emotional experience and the App interface information structure will be built.Finding principle and method of design from the information structure and state for the information carding.And explain and demonstrate from actual project case,for the applicability of the design principle and method of visually impaired users interface design.The annotation of this paper is that it intermeshed investigational methods.It uses questionnaires to investigate the visually impaired population and combines multichannel model designing method based on the function and interaction information design.It create a brand new design for interface information in aspect of auditory and tactile.It adheres the thinking of raising the problems-analysis the problems-solving the problems.And scientifically summarize a set of design principle of App interface design for visually impaired users.
