The methodology of developing a mobile application design for creating a genealogical tree

Abstract

The aim of the study is to develop a mobile application design to create a genealogical tree. The article focuses on the subtleties that need to be considered when designing an interface. The creation of an intuitive family tree in this paper is proposed on the basis of the online service Coggle, which is designed to develop mental maps. During the development process, the task was set to place many functions of the mobile application so that the user was comfortable and understandable to use them and there were no redundant design elements. As part of the study, the design for the mobile application of the family tree should be developed for the Android platform. The paper presents and analyzes the main criteria that should be in the program for mobile application development. The list of the basic stages which are necessary for creation of design of the mobile application for development of a genealogical tree is resulted. The article offers a general structure of the mobile application. The general features of preparation of styles of the basic colors and fonts are analyzed. A system of requirements that should be taken into account in the process of creating an interactive prototype of a mobile application of the family tree is presented. Based on the system of requirements, an interactive prototype of the mobile application was created, where the systems of transitions between pages and animation of transitions were implemented. This study also describes the settings for the created pages of the application and implemented navigation in the application with different types of transitions of such types as interactive click navigation, overlaying a new element on the page and horizontal and vertical scrolling. The practical result of the study is a list of recommendations to the designer and developer regarding the design of a mobile application for creating a family tree.
