Presentation System of Still Picture Teaching Material Using the Implant-JPEG

摘要

The authors developed a presentation system for still image teaching materials, which enables various image information embedded in still images on the World Wide Web to be displayed while synchronizing that information with audio explanations and also enables other related image information to be referenced interactively. This paper presents an overview of the presentation system and reports on a creation tool for still image teaching materials, which supports the creation of still image teaching materials to be used in the presentation system. The presentation system's viewer, which is provided to enable the user to accurately understand the image information, has functions not only for changing the display of the image that was pointed to so that the indicated image can be differentiated from other images but also for displaying explanatory text for the image and displaying additional information such as information for other related images. In addition, the system's search function enables the user to find a high-level concept to which the image information belongs and easily retrieve other picture information having the same high-level concept. The presentation data can be easily maintained and managed by putting together and distributing the information for the still image and each partial still image in an implant-JPEG format file called a capsule.
