The interactive system which interacts human with computer has been recognized as one direction of computer development for a long time. For example, in cinema, a person gets information he wants or plays the media data while moving by using a mobile device. As the development of this system, we designed and implemented the system interacts with users in a small terminal. Our study has three categories. The first category is the development of new interactive media markup language (IML) for the writing interactive media data. The second category is the IML translator which translates IML into the best form to be played on mobile device. And the third category is the IM player, which plays the transferred media data and interacts with user. IML was designed for controlling vector graphics and general media objects in detail and supporting synchronization. Also, it was designed to be operated in small mobile device as well as desktop PC or set-top box which has high CPU performance. The...
