Research On An Interactive Graphics Toolkit For Mobile Applications And Its Implementation

In recent years, with the constant popularity of mobile devices, a variety of software applications flooded in people's lives. The development of application is increasingly focusing on the user-centered design, promoting good user experience, which bring new challenges to user interface designers and developers. First, the input modal of mobile device is different from the conventional PC's and the interactive approach is also changed. The user interface development technology of the traditional PC is not suitable for mobile devices. Secondly, the development of graphics in mobile interface is extremely complicated, and does not possess interactive features, either. It can't provide effective and high-efficient operation for the user.In the user interface of traditional PC, the application of visual object and operable graphical representation are not only easy to understand but also can improve the efficiency of the operation, which is widely used. Nowadays, it is also widely used in Web applications and mobile devices. However, the current mobile platform develop operable graphic objects in user interface window based on platform providing low-level graphical objects and events mechanisms. The process is tedious and time-consuming, not having high availability interactive features. Constructing an interactive graphical toolkit can provides a possible solution on mobile platforms. Making the operable graphic objects and specific interactive semantic package can help the developers to design user interface without caring the graphics rendering and interactive semantic computation. By introducing interactive graphical into the development of mobile user interface and designing the interface with graphic objects with interactive features as the basic unit, it can effectively improve the interactivity and usability of application software. However, the mobile user interface development platform does not provide support for interactive graphics developers. The developer still need to encode manually in order to achieve interface graph and interactive event added, and its code does not have reusability.In order to solve the above problems, this paper proposes an interactive graphical toolkit based on mobile platform, named MIGT. The toolkit improves the present interactive graphics development technology, which can enhance the efficiency of mobile user interface development and the usability of interface. The toolkit system has two main characteristics. On the one hand, using a XML-based description language describe interactive graphics. It can not only be applied directly to the development tools, reducing the learning curve for developers, avoiding second hand coding, which can improve the efficiency of interface development. On the other hand, designing and achieving interactive graphic base and its presentation model and event model, separating graphics and interactive events can reuse graphical elements and interaction events and improves the user interface's interactivity and usability effectively. Finally, this paper uses an interactive living housekeeper example to verify the feasibility and effectiveness of the toolkit system.
