In ancient times, information was recorded using some characters and/or artistic pictures to transfer their historical circumstances. During the 18th and 19th centuries when storage methods of sound were developed, information contained not only the text and artistic pictures but also raw auditory information from the real world. Furthermore, cameras were found to be helpful in processing static and dynamic visual information. By using various techniques in wide fields, we can handle text documents, sound, and visual information. In recent years, communication technologies have grown rapidly. The growth of the Internet enabled transmission information including text, sound, and video files worldwide. However, information stored by conventional devices does not contain haptic information, although the human body has haptic organs as well as auditory and visual organs.
