Research On The Extraction Of Interactive Features Of Flash Animations

With the rapid development of computer technology and network informationtechnology,resources for learning network is also attend more and more attention of schools andcountries.Flash uses the technology of vector graphics and streaming media technology whichmade the Flash animation files has simple manufacture, the unique visual effect,faster speed oftransmission on the internet, more flexible online interaction.So Flash animation has been rapiddevelopment. Flash animations since its inception in1999with its unique advantage has becomeexcellent teaching and learning resources, which are widely used. Flash animations with itsstrong interactive ability can make the students from learning resources recipients into learningresources participants, so that it can better stimulate learners interest in learning, improvelearning efficiency. Not only a good learning resources, in the teaching of Flash animation for itsvivid concrete demonstration of teaching content it is also teachers’ love. Compared with thetraditional education teaching resources, Flash animation as a new visual media resources, whichnot only can be embedded in graphics, video, sound, text and other elements in different mediaobjects, you can also use the mask, filter, deformation characteristics of generating morecomplex dynamic visual effect and changeable and movie clips can be achieved; multiple nestedbetween different video clips and call each other, through the buttons, movie clips and the timeaxis set action script to achieve Flash animations’ strong interactivity, control etc…Based on theabove characteristics, the current Flash animation with an irresistible force becomes a form ofnetwork multimedia resources in the most popular in today’s digital age. SWF file is a form ofrelease Flash animation According to statistics, the world browser percent more than ninetyembedded Flash player (FlashPlayer) used to play SWF files. Flash animation is widely usedespecially the interactive application in education and teaching makes the interactive analysis ofthe characteristics of Flash animation and its extraction research has become an important topic Therefore, this article from the interactive feature elements of the Flash animation starting,explore the retrieval of Flash animation interaction feature based on content, analysis andextraction of interactive features to achieve the Flash animation composition element, is one ofthe research and development achievements of ontology Flash content management and searchengine system.In this paper, the author start from the released of Flash file (.swf) format specification based,applied the tool of object-oriented Visual C++programming, add the interactive feature analysisof content features Flash animation elements of the platform in the extraction and analysis anddrag the button interaction, follow the mouse, analyzing and extracting the keyinteraction.Through the comprehension of reading instruction and SWF file labelinformation,the author analysis and extraction interactive elements of Flash animation featuresuch as button labels and displays information about the interactive feature list tags to follow themouse events and key events.The paper extract the features and semantic and add it to thecorresponding feature index database, content the retrieval system based on Flash service,increase the interactive property, from the interaction point of search of Flash animation, whichcan improve the retrieval accuracy and efficiency; provides browsing returned to the interface forthe Flash retrieval system, learning, teachers and students used to provide more accurate, vivid,comprehensive Flash resources, thus digital learning environment to improve the learners’learning efficiency, promote the development of the digital education resource.
