Interactive Graphic Research For Mobile Devices

The Interactive Graphics has been widely used on PC platform by its numerous merits, including metaphor ability、direct manipulation and the feature that what you see is what you get. Furthermore,we can experience visual culture and aesthetic value from interactive graphics. With the phenomenal development of IT technology, we have transited from PC period to mobile period. According to the investigation and analysis done by us, we found that the Interactive Graphics remains to have application prospect. However, the Interactive Graphics is not widely used on mobile platform by now, which is subject to following two aspects:the first one is the process that developing Interactive Graphics application is inefficient. The mobile platform only provide static graphics render library but not interactive graphics library, so it is difficult to build graphics object and maintain the relationship between those objects effectively. The second one is that there is no effective Interactive Graphics transmission machanism, then users can’t get good experience in online inter-operations. Therefore, a protocol to transmiss Interactive Graphics between mobile devices is urgently needed.Aim at those above-mentioned problems, this paper designed and realized a mobile device oriented light-weight Interactive Graphics library(MDO-LWIGL)and an Interactive Graphics transmission protocol based on XML(MIGTP). MDO-LWIGL is based on MVC architecture, including render、event handler and object manager. By use of this library, it’s only need to define graphics objects by ignoring how to render graphics objects in the development of Interactive Graphics application. So it becomes easy to handle interactions on those objects. MIGTP can describe Interactive Graphics objects and interaction events based on XML, which is a declarative language. So MIGTP can mask platform and hardware differences between mobile devices. By realizing the MIGTP generator and parser, the MIGTP content can be transmissed transparently, which can be an effective solution to transmiss Interactive Graphics between heteroplasmic mobile devices.To validate the correctness and validity of MDO-LWIGL and MIGTP, this paper finally realized a demo example named "Online Renju". Here the detailed design and realization were presented.
