An Approach to Interactive Media System for Mobile Devices

摘要

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 player, implemented finally, is operated on PDA (HP iPAQ) and plays the multimedia data consist of vector graphics (OpenGL), H.264 and AAC etc. according to the choice of user. This system can be used in the ways of interactive cinema and interactive game, and can substitute new interactive web services for existing web services.
