Digital transformation is driving so many changes in daily life and industry. The automobile industry is in a similar situation. In some cases, element techniques in areas called metabuses are also being adopted, such as 3D animated digital cockpit, around view, and voice AI, etc. Through the growth of the mobile market, the norm of human-computer interaction (HCI) has been evolving from keyboard-mouse interaction to touch screen. The core area was the graphical user interface (GUI), and recently, the audio user interface (AUI) has partially replaced the GUI. Since it is easy to access and intuitive to the user, it is quickly becoming a common area of the in-vehicle experience (IVE), especially. The benefits of a AUI are freeing the driver's eyes and hands, using fewer screens, lower interaction costs, more emotional and personal, effective for people with low vision. Nevertheless, when and where to apply a GUI or AUI are actually different approaches because some information is easier to process as we see it. In other cases, there is potential that AUI is more suitable. This is a study on a proposal to actively apply a AUI in the near future based on the context of various scenes occurring to improve IVE.

Conventional home audio system (e.g. AV Receiver, CD Player etc) has a various functionality of audio play, channel mixing, but the remote controller of these audio players is too complex, difficult for user to manage them effectively. Users want to use these functionalities with more easy, comprehensible way. In this study, "intelligent real-sound presentation technology" that support high quality, realistic audio and the "design of complex information and controller of real sound using intelligent real sound play and control interface" will be introduced. So user can actively, realistically enjoy and play real sound based on user's preference, emotion and circumstance, instead of user's passive service.

Mobile device has a constraint such as a small physical display size and interaction. One of the most important issues in mobile devices is the express an identity of one's products company. It can be appeal to the user in side of consistency. Thus, we integrate and extract an identity element from user experience including, Graphical User Interface, Information Architecture and Audio User Interface. The study was conducted by a task force team with User Interface practitioners of managing divisions of each product. In this study, methods and processes that were attempted in order to establish consistency principles of user experiences, enhancing the various characteristics of each product, are described. The results and practical experiences obtained through the processes are introduced.

전통적으로 기존의 제품은 정적인 환경에서의 학습과 언어적인지가 중요시되며, 제품 조작 시에도 커뮤니케이션의 많은 부분을 시각적 인터페이스에 주로 의존한다. 그러나 기술의 진보와, 사회환경의 변화에 따라 많은 제품들이 휴대용 제품으로 변화하고 있으며, 제품의 크기 또한 경박단소화되어 제품의 사용방법이 점점 더 블랙박스화 되어 가고 있다. (중략)

Audio-based SNS also needs a visual guide to reach the contents desired by the users. Therefore, this study investigates visual interface design elements that influence the experience of using audio contents in audio-based SNS. Prior researches have identified that the generally acknowledged interface design elements are important for the usability of audio contents. Through the analysis of the currently launched audio-based SNS, the influence of general interface elements were again confirmed, and via the analysis of other audio content services, a new interface evaluation element was explored. Accordingly, with five general interface evaluation elements-layout, color, icon, typography, graphic image, multimedia elements are newly defined and proposed as crucial factors in evaluating the UI of audio-based SNS.

In this paper, we can confirm the result of intuitive interface software implementation for operating a digital PA(Public Address) controller and the performance of audio mixer control part. Developed user interface software provides the maintaining management and control function of digital hybrid mixer. This SW loaded in the integrated control server controls an sound status of the audio mixer TAD-168M and checks the device status for Public Address integrated system. Also, this SW enables the integrated control and the continuous upgrade. Developed SW is connected to TAD-168M with Ethernet and linked to PC Lan port and the 4-port switch, located in the backside of TAD-168M, by LAN cable for communicating with operating PC. Integrated control including system management, audio control and uplink broadcasting control for broadcasting system will be made available with this novel developed system.

In this paper, we introduce an interface for exploring music using emotional model. First, we survey arousal-valence factors of various music and calculate a correlation between audio fefatures of music and arousal-valence factors to build an AV model. Then, various music is aligned and arranged using the AV model and the user can explore music in this interface. To select the desired music more intuitively, we introduce new fade in/out function based on the location of the user's mouse point. We also offer several mode of selecting music so user can explore music using most suitable mode of interface. With our interface, the user can find the emotionally desired music more easily.

Recently DSP chips are widely used in high quality car audio to achieve high quality sound and to process various sound sources, e.g. navigation, cell phones. In this paper, we developed a set of design tools useful for developing high quality car audio systems using Philips' SAF7730 car audio chips. The tool is consist of the GUI(Graphic User Interface) program running on the Windows operating system and the interface board which performs data conversion between RS232C and I2C protocols. The developed system has been successfully applied to commecial car audio design.

AUI(Advanced User Interaction) interface aims to enhance interaction between various input/output devices and scene descriptions represented by video, audio, and graphic. Recently, MPEG-U part 2 standardization for the AUI interface is under development by MPEG(moving picture experts group). This paper introduces MPEG-U part 2 standard and presents MPEG-U part 2 AUI interface system. The AUI interface system consists of user interface in/output modules and MPEG-U XML generation/interpretation modules. The former and the latter are for UID data handling and XML data processing, respectively. This system MPEG-U standards-based input/output devices and to improve the interaction with the user can be used as a framework. By implementation of the proposed AUI interface system, MPEG-U usage scenario is introduced and it is verified that the AUI interface system conforms to MPEG-U standard.
