In this class, the definitions of media, multimedia and multimedia system will be clarified and the usage of them will be
investigated from the engineering viewpoint. Especially, focusing on the information and communication technologies with graphics,
visual information processing and human sense in engineering will be explained. In addition, how to quantify the psychological
values of auditory information and visual information will also be mentioned. Finally, 3D display technologies will be introduced.
The purpose of this class can be divided into two. One is to comprehend the technologies which connect the physical quantities
obtained by auditory and visual senses with the psychological values acquiring the concepts of media, multimedia and multimedia
system. The other is to comprehend 3D display technologies acquiring human's stereoscopic elements.
- To comprehend multimedia systems based on the characteristics of human's auditory sense, voice and visual sense.
- To comprehend how to quantify the human senses.
- To comprehend 3D display technologies.
