Automation and mechanization of work make people put the machine into operation and watch the state of operations. In the process of those works, they are apt to have accidents caused by their carelessness. To reduce such accidents, we can practise TOUCH and CALL, which Is to Indicate and ascertain the dangerous parts at every process before performing works. The objectives of thls study are to show quantitatively the efficiency of TOUCH & CALL and to examine the effects of S-R compatibility. The results show that reaction time is longer(0.138-0.279sec.) in case of indicating with finge,s and shouting than that of responding only visually. On the other hand, the error rate decreases by 3.3 times-7times. From this, it is considered to verify quantitative estimation on multiple feedback of TOUCH & CALL.

Automation and mechanization of work make people put the machine into operation and control the state of operation. In the process of those works they are apt to have accidents caused by their carelessness. To reduce such accidents, we can practice "TOUCH '||'&'||' CALL", which is to indicate and ascertain the dangerous parts at every process before performing tasks. The objectives of this study are to examine the effects of S-R compatibility and to show quantitatively the efficiency of TOUCH '||'&'||' CALL. The results show that: 1. Reaction time in case of indicating with fingers and shouting is slightly longer (0.138sec. .approx. 0.279sec. ) than that of responding only visually. However, the error rate decreases by 1/3.3 .approx. 1/4.2 times. Frome this, it is considered to verify quantitative estimation on multiple feedback of TOUCH '||'&'||' CALL. 2. In the stimulus-response relation aspect, numeric numeric stimulus-numeric response shows lower error rate (0.033% .approx. 0.133%) than any other stimulus-response relation, ahd shorter reaction time is proven ( 0.556sec. .approx. 0.835sec. ). These data suggest that having the order of stimulus-response arranged in accordance with the experimental knowledges and conceptional compatibility can bring down the error rate considerably.

This paper describes the automated call routing for call center system based on speech recognition. We focus on the task of automatically routing telephone calls based on a users fluently spoken response instead of touch tone menus in an interactive voice response system. Vector based call routing algorithm is investigated and normalization method suggested. Call center database which was collected by KT is used for call routing experiment. Experimental results evaluating call-classification from transcribed speech are reported for that database. In case of small training data, an average call routing error reduction rate of 9% is observed when normalization method is used.

This paper describes the automated call routing for train ticket reservation aid system based on speech recognition. We focus on the task of automatically routing telephone calls based on user's fluently spoken response instead of touch tone menus in an interactive voice response system. Vector-based call routing algorithm is investigated and mapping table for key term is suggested. Korail database collected by KT is used for call routing experiment. We evaluate call-classification experiments for transcribed text from Korail database. In case of small training data, an average call routing error reduction rate of 14% is observed when mapping table is used.

본 논문에서는 유아를 대상으로 한 에듀테인먼트 콘텐츠에 대하여 기술한다. 우리나라 전통 음악인 국악을 사용자가 실제 악기가 아닌 가상 악기를 이용하여 체험해 볼 수 있고, 국악에 하나인 판소리를 따라 부를 수 있게 한다. 또한 전통문양과 기본도형을 이용한 놀이를 직감적 도구인 손을 이용하여 디스플레이를 직접 터치할 수 있는 지능형 인터페이스 플랫폼인 Touch-Face를 기반으로 조작이 익숙하지 않는 유아 및 아동들이 쉽고 편리하게 조작할 수 있게 하였다. 이러한 기반 위에 교육적 콘텐츠는 보다 더 유아 교육에 있어서 효율적으로 학습하는데 도움이 될 수 있다.

As technologies have been developing, our lives are getting easier. Today we are surrounded by the new technologies such as AI and IoT. Moreover, the word, "smart" is a very broad one because we are trying to change our daily environment into smart one by using those technologies. For example, the traditional workplaces have changed into smart offices. Since the 3rd industrial revolution, we have used the touch interface to operate the machines. In the 4th industrial revolution, however, we are trying adding the speech recognition module to the machines to operate them by giving voice commands. Today many of the things are communicated with human by voice commands. Many of them are called AI things and they do tasks which users request and do tasks more than what users request. In the 4th industrial revolution, we use smartphones all the time every day from the morning to the night. For this reason, the privacy using phone is not guaranteed sometimes. For example, the caller's voice can be heard through the phone speaker when accepting a call. So, it is needed to protect privacy on smartphone and it should work automatically according to the user context. In this aspect, this paper proposes a method to adjust the voice volume for call to protect privacy on smartphone according to the user context.

음성자동응답시스템(Automatic Response Systems, ARS)은 VUI(Voice User Interface)와 TTI(Touch Tone Interface)를 기반으로 하고 있으며, 현재 가장 널리 사용되는 커뮤니케이션 시스템 중 하나이다. 그러나 많은 사용에도 불구하고, ARS에 대한 불편 사항들이 끊임없이 지적되고 있다. 이는 기술 개발을 넘어, 사용자와 사용성에 대한 체계적인 연구 부족에서 기인한 측면이 있다. 본 논문에서는 ARS 메뉴체계에서의 사용성 저해 요소를 발견 분석하여, ARS 설계를 위한 개선의 지침을 제공한다. 두 개의 인터넷 서점 ARS를 선정하여 피실험자들이 "도서 반품 신청하기"라는 작업을 실행한 후 정해진 설문조사 결과와 인터뷰 내용을 분석하였다. 본 연구에서 메뉴 구조의 복잡성, 메뉴명의 대표성 부족, 사용자 위치인지의 어려움, 메뉴간 이동의 어려움 등 네 가지 문제들을 발견하였고, 이를 피할 수 있는 방법들을 논의하였다.

Communicating devices for the seriously disabled using eye-ball movement or some body movement are proposed. The first one is a device to use image processing, whose input signal is eyeball movement, A feature of this device is that the device can be readily realized using a note-book computer with USB (Universal Serial Bus) interface bus. This device is incorporated with a word processing software called Nearly Ladder. The second one is an emergency call switch which is used by a patient who can move his finger slightly. The patients can switch on the emergency switch only by touching a switch with his finger. The essence of this sensor is a touch sensor. The sensor can be realized using onl...

Questionnaire survey has been made for the above study. First, 65 question sheets have been distributed to railway operators and 55 sheets of them have been collected from them. SPSS 12.0 program package has been used to analyze those sheets concerning age, experience, school, background as a frequency analysis and t-test has been made to find out recognition level difference of a cheer response, depending on the operator's experience. T-verification has been made for two groups such as less than 10 years, and 10 years or more experience. Result from correlation analysis showed that there was no difference due to operators' experience.

스마트 미러는 거울에 디스플레이와 임베디드 컴퓨터를 부착하여 거울 기능과 함께 사용자에게 다양한 정보를 제공해주는 IoT 장치이다. 본 논문은 스마트 미러가 사용자에게 정보를 제공하는 독립형 장치(stand alone device)라는 개념에서 벗어나 스마트 미러들이 연결되는 네트워크를 구성하고 사용자들이 다른 스마트 미러 사용자들과 대화하고 정보를 공유하는 CoMirror 시스템을 제안하고 구현하였다. CoMirror 시스템은 1개의 CoMirror 서버를 중심으로 여러 CoMirror 클라이언트들이 연결되는 구조이다. CoMirror 클라이언트는 라즈베리파이와 미러 필름, 터치 패드, 디스플레이 장치, 웹 카메라 등으로 구성되며, 서버에는 얼굴 학습과 인식, 사용자 관리, 클라이언트들 사이의 메시지 교환을 위한 중계 역할, 화상 통화 연결 설정 등의 기능이 구현되었다. 사용자들은 서버를 경유하여 다른 CoMirror 사용자들과 텍스트, 이미지, 오디오 등의 메시지를 주고받을 뿐 아니라, 1:1 화상 통화를 할 수 있도록 구현되었다.
