Design And Research Of The Touch-operation-based Dynamic Geometry Software

In the background of educational informationization,this study focuses on two questions: What is the status of development about dynamic geometry software from PC-based to smart mobile terminal devices;how to design a touch-operation-based dynamic geometric software that is intelligent,friendly and welcomed by learners.The study found that the current dynamic geometry software in the design did not fully consider the characteristics of mobile devices,operating gestures have no uniform norms and standards to guide,and lack of feedback,which result in poor user experience.The user expectations for dynamic geometry software from high to low are: easy to operate,simple interface,powerful,fun gesture operation,easy to share.To solve the above problem,we do concise design to the user interface of the geometry software program in this paper,and use the general gestures which are natural and easy to understand to make the operation more convenient and simple.Drawing based on the basic graphics and gestures design are the important and difficult points of the research,after canceling the secondary menu,we need to create logical relationship between the basic graphics classes and their associated sub-classes,then rebuild and show the new object by reading the object ID and their attribute relationship,which means we achieve drawing based on the basic graphics by the h uman-computer interaction method of what you think is what you get;on the gestures design,with full consideration of the features of the touch mobile devices and the user's operating habits,we introduce many gestures to perform different functions,and make the operation more simple and quick.We build Android development environment and achieve the basic drawing functions of the software which is based on the needs of users,and propose overall design of touch-operation-based dynamic geometry software,then put forward the system development framework and process from user experience perspective,which can provide a reference for similar project design and development.
