Research On The Application Of 2.5D Illustration In App User Interface Design

With the advent of the new media era in China,the art of illustration also shows diversified development.2.5 D illustration emerges as the times require.The combination of technology and art has taken on a new look.APPS have gradually become a part of our lives,whether from learning knowledge to life shopping or entertainment in the hands of mobile APPS,convenient and fast apps also enrich our way of life.Poverty Alleviation has also been a policy called for and implemented by the state to improve people’s livelihood.The "cloud food basket" poverty alleviation APP enables the poor groups to make use of the APP to sell agricultural and sideline products and enlist resources from the society to help them,on-line get the help of caring people,so as to achieve the goal of poverty alleviation and create social value.2.5D illustration is now widely used in many design fields,such as APP,website,e-commerce product poster,game picture and so on.Through the relevant theory and case analysis of 2.5 d illustration and APP user interface design,this paper deeply studies the application of 2.5 d illustration in APP user interface design,this paper summarizes four design principles of 2.5 d illustration in APP user interface design,including unity principle,individuation principle,practicality principle and emotion principle.This paper summarizes the basic visual form of 2.5 d illustration in the APP instinct layer,the interaction experience between the behavior layer and the APP interface,and the emotional resonance between the user and the APP on the reflective layer.In order to meet the deeper emotional needs of users and personalized experience.In the part of design practice,this paper takes "cloud food basket" as the research object,studies the applicability and functionality of the APP,and analyzes the current application status of the APP.The feasibility of 2.5D illustration in the design of APP user interface is verified in practice.
