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.

본 논문은 XML의 여러 응용분야 중에서 악보를 XML로 표현하는 기법에 대한 기존의 연구 현황에 대해 알아보고자 한다. 악보를 XML로 나타내는 방법에는 musicML, scoreML, musicXML, musiXML등이 있다. 이러한 악보를 XML로 나타내는 방법을 응용하여 music XML과 데이터베이스와 연동, musicXML을 이용하여 입력된 악보를 MIDI(Musical Instrument Digital Interface) 파일형식으로 Web상에서 연주하도록 하는 방법에 대해 알아보고자 한다. 이러한 music XML 현황연구를 통해 그 동안의 연구과정에 대해 알아보고, 더 나아갈 방향을 제시하도록 하겠다.

As the market of music download stores moved into the mobile epoch the market was growing explosively. Recently, the digital music market tends to move from the mp3 download market to streaming service and the users can use the service on their mobile devices without reference to any inconvenient download and limited storage capacity. It was found that they mainly use the recommendation music playlist, instant player, main player and sharing of the functions of the streaming service from the user behavior research. This is noticeable features that set apart from the mp3 download service. However, the interface design of the streaming app followed the previous service and it needs the optimization of its UI design. In this study, the usability of high ranked three mobile streaming apps was evaluated. The result of the test was that Naver music and Bugs had high scores overall in four sections of the streaming service features. On the other hand, the Melon had primarily high score in color application on the service. The aim of this study is to suggest the direction of the UI design of music streaming service through the understanding of essence of streaming service and evaluation the usability test.

People have tendency of forgetting music title, though they easily remember particular part of music. If a music search system can find the title through a part of melody, this will provide very convenient interface to users. In this paper, we propose an algorithm that enables this type of search using feature transformation function. The original music is transformed to new feature information with sequential melodies. When a melody that is a part of search music is given to the system, the music retrieval system searches the music similar to the feature information of the melody. Moreover, this transformation function can be easily extended to various music recognition systems.

Previous studies of music, user interface, and human-computer interaction have used sounds which include musical structure rather than real music. This study investigated whether real music affects objective and perceived usability. Silence, sound, and music conditions were compared in experiment 1 (kimchi refrigerator) and 2 (remote controller for air conditioner). Participants' performances of reaction time and accuracy, and the degree of subjective satisfaction were analyzed. The results showed that main effects on task performances were not different significantly; however, perceived usability of music condition was better than sound condition, which was better than silence condition. It means that musical user interface improves perceived usability while not interfering task performance. This study provides a basis of emotional and aesthetic effects of music in home appliances design, and can be applied to studies for the blind. More specific guideline for the musical user interface can be drafted if further studies consider more various tasks, context, musical structure and types for the appliances.

In this paper, I describe about edutainment contents to infant. We can call following PANSORI that user can experience national classical music that is our country tradition music using imagination musical instrument instead of actuality musical instrument, and is one at national classical music. Also manufacturing operationalized Touch-Face that is intelligence style interface platform that can play that tradition pattern and basis use style hand that is a tool the immediate perception enemy use and touch display directly as unaccustomed infant and children are easy and convenient to base. Because of these reason, educational contents can become help to study efficiently because there is in preschool education more on Touch-Face base.

In this paper, we carried out recognition experiments for noisy speech having various levels of car noise and output of an audio system using the speech interface. The speech interface consists of three parts: pre-processing, acoustic echo canceller, post-processing. First, a high pass filter is employed as a pre-processing part to remove some engine noises. Then, an echo canceller implemented by using an FIR-type filter with an NLMS adaptive algorithm is used to remove the music or speech coming from the audio system in a car. As a last part, the MMSE-STSA based speech enhancement method is applied to the out of the echo canceller to remove the residual noise further. For recognition experiments, we generated test signals by adding music to the car noisy speech from Aurora 2 database. The HTK-based continuous HMM system is constructed for a recognition system. Experimental results show that the proposed speech interface is very promising for robust speech recognition in a noisy car environment.

This study was to investigate the influence of using Therapeutic Instrumental Music Performance (TIMP) in uninvolved hand function for children with spastic cerebral palsy. Participants were recruited from a welfare center for people with cerebral palsy(CP). Ages ranged from 11 to 12, and a total of 15 TIMP sessions were provided for 3 weeks. Hand function tests were used including Jebsen Hand Function Test for hand function, Box and Block Test for dexterity of uninvolved hand, and MIDI (Musical Instrument Digital Interface) evaluation for velocity of fingers. The TIMP program consisted of hand percussion playing and keyboard playing with changes of timbre and tempo. While the scores of Jebsen test and Box and Block test were improved for all participants, outcomes of MIDI analysis showed differences among participants. Overall, hand function improvements were observed after the completion of using the TIMP program, and the results implies that the TIMP program can be applied in upper extremity rehabilitation for children with CP.

The purpose of this study was to define the effects of noise and background music on the trunk muscle fatigue during dynamic lifting and lowering tasks. Six healthy male subjects with no prior history of low back disorders participated in this study. The participants were exposed to two levels of background noise such as 40dB noise and 90dB noise and three levels of background music such as no music, slow music, and fast music. Six different combinations of background noise and background music were played while the participants were performing the lifting task at 15% level of Maximum Voluntary Contraction. Electromyography signals from six muscles were collected and fatigue levels were analyzed quantitatively. In results, the 90dB noise increased trunk muscle fatigue and slowed down the recovery. The trunk muscle fatigue was the lowest when the fast music was played for as background. After recovery, the 90dB noise increased trunk muscle fatigue. The trunk muscle fatigue was the lowest when the slow music was played for as background. The results can be useful to manage the cumulative fatigue of trunk muscles due to background noise and music during repetitive lifting and lowering tasks in industry.
