I. Introduction

Focus: issues and techniques of creating and using multimedia content indication
-Not easy to design an effective multimedia interface that allows us to make full use of multimedia
-Past vs. Present
-Need effective representations of multimedia contents

II. Issues

-Multimedia Interface Cycle (fig. 7.1)

Issues in coping with the problems of the multimedia interface cycle:

• Interface design that realizes intuitive and effective interactions appropriate for the application and usage. It should follow our information comprehensive style. This is the focus of this chapter.
• Structure in data description and processing which realizes the above interface design with high flexibility and efficiency.
• Processing algorithms that support the efficient data handling in computers.
