Research On Visual Design Of Map App Based On Color Vision Impaired Users

In China today,all kinds of service-type mobile phone apps have long been able to achieve a large scale and large area of population coverage.Among them,map service apps,which are related to the safety and convenience of people’s travel in "food,clothing,housing and transportation",are even more indispensable.Today,all kinds of service-type apps ignore special groups when providing services to the majority of users,and there is still little research in the field of meeting the service needs of special groups,The "people-oriented" advocated by modern design philosophy also includes these special groups as service objects,which requires us to break the boundaries of design and promote the development of design and social progress from a higher ideal level.This design study will be based on the interface guidance design of the map service type app of the mobile client,optimize and improve the interface of the existing map APP in the market to better meet the needs of the color vision impaired user group,help the color vision impaired user group to better use the map app,optimize the sense of experience,and solve the travel difficulties in life.
