Communication is one of the very important factor in MMORPGs where a large number of users participate at the same time. The voice chatting system, which was appeared in the development process of the chatting system, failed in Korea but it was a great success in China. The purpose of this study is to analyze this cause. The research scope of this study is as follows. We set the range of this study from 2003 to 2015. This period covers the beginning of the growth of the Chinese game industry up to the present. The research target games are MMORPGs, which ranked 1st in sales and concurrent users. In the research and survey analysis process, various factors such as the input speed of Chinese and Korean characters and the relationship between men and women were investigated and analyzed. In conclusion, chatting system in Chinese MMORPGs has developed into three stages and we found out that voice chatting in China was relatively popularized rather than in Korea. China's slow typing speed and excellent voice chatting system were the main factors.

Applying the concept and components of human nature to the conversational agent in the smart home context, this study investigated the effects of the level of anthropomorphism and interaction type on the emotional user experiences and future use intention. The results of experiment study showed that the high-low condition of anthropomorphism and the voice-chatting interaction type have impacts on the perceived closeness, likability, and future use intention. That is, people evaluate the conversational agent as more close, likable, and useful when they perceive more human nature components and when in the voice interaction mode. Psychological resistance was lower in the voice than in the chatting mode regardless of the level of anthropomorphism. The results also demonstrated an interaction effect of anthropomorphism and interaction type on the future use intention: the effect of anthropomorphism existed only in the voice interaction mode. It leads to the conclusion that a conversational agent with the voice recognition interface should be designed with the higher level of human nature components for the continuous use.

최근, 스마트폰 가입자 수가 1000만 명을 넘어설 전망으로 한국은 스마트폰 열풍이며 그중에서도 안드로이드 사용자가 폭발적으로 늘고 있는 추세다. 이러한 추세에 발맞춰 사람과 사람의 관계에 중심을 두는 서비스인 SNS가 급격히 성장하여 모바일의 장점을 살린 음성중심의 모바일SNS, 즉 보이스 채팅 시스템이 많은 인기를 끌고 있다. 그러나 기존 보이스 채팅 시스템의 대화상대 선정, 참여자들 간의 유대감 형성, 발언권 확보와 같은 주요 문제점들을 해결하기 위해 그룹형성, 멤버위치표시, 인원제한을 이용가능하게 하는 CCG(Closed Chatting Group, 폐쇄형 채팅 그룹)라는 '개설자의 현재 위치를 중심으로 형성된 채팅 그룹'을 도입한 CCG기반 보이스 채팅 시스템을 제안한다. 또한 기존의 사용성 낮은 디자인을 사용자 중심의 인터페이스 디자인을 사용하여 편리성을 제공한다. 사용자 중심의 CCG 기반 보이스 채팅 시스템인 SIC는 마음에 맞는 다양한 사람들과 원활한 커뮤니케이션을 할 수 있도록 도와 줄 것이다.

After COVID-19, various metaverse platforms for online lectures are being provided. Most of the classrooms are tiered type, and they are divided into intensive classrooms and open classrooms depending on the shape of the classrooms. Intensive classrooms provide a one-sided lecture format, so there are many difficulties in conducting communication-based classes that carry out team missions like PBL classes. In this study, we propose a metaverse classroom that applies the functions of a multiplayer online role-playing game (MMORPG), one of the game genres suitable for PBL classes. The proposed system provides various interaction techniques for PBL classes. We evaluated user satisfaction when this was applied to actual classes. As a result of the evaluation, it was found that users preferred text and voice chatting more than video chatting and solving missions like games was very helpful in online classes.

Voice user interface has become a commercially viable and extensive interaction mechanism with the development of voice assistants. Despite the popularity of voice assistants, the academic community does not utterly understand about what, when, and how users chat with them. Chatting with a voice assistant is crucial as it defines how a user will seek the help of the assistant in the future. This study aims to cover the essence and construct of conversational AI, to develop a classification method to deal with user utterances, and, most importantly, to understand about what, when, and how Chinese users chat with voice assistants. We collected user utterances from the real conventional database of a commercial voice assistant, NetEase Sing in China. We also identified different utterance categories on the basis of previous studies and real usage conditions and annotated the utterances with 17 labels. Furthermore, we found that the three top reasons for the usage of voice assistants in China are the following: (1) greeting, (2) function, and (3) music. Chinese users like to interact with voice assistants at night from 7 PM to 10 PM, and they are polite toward the assistants. The whole percentage of negative feedback utterances is less than 6%, which is considerably low. These findings appear to be useful in voice interaction designs for intelligent hardware.

In this paper, a VoIP (Voice on Internet Protocol) terminal system, which can process voice in real time based on Linux, is designed and implemented. The hardware of it is designed using a i486 processor and a DSP codec chip which encodes and decodes voice data in real time. As an operating system, RTLinux, which is a real-time operating system based on Linux, is ported to manage real-time voice processing. The voice processing module of the system uses G.723.1 voice codec of ITU-T standard. It transfers voice data within 30ms to assure good voice quality. In order to satisfy the real time requirements and QoS (Quality-of-Service) for the voice data, the real-time voice processing device driver is designed and implemented. To verify the system, the chatting application program is developed and tested for QoS of the system.

This paper presents an active assisted-living system in wireless sensor and actor network (WSAN) in which the mobile robot roles an actor. In order to provide assisted-living service to the elderly people, position recognition of the sensor node attached on the user and localization of the mobile robot should be performed at the same time. For the purpose, we use received signal strength indication (RSSI) to find the position of the person and ubiquitous sensor nodes including ultrasonic sensor which performs both transmission of sensor information and localization like global positioning system. Active services are moving to the elderly people by detecting activity sensor and visual tracking and voice chatting with remote monitoring system.

The educational effect and practical use of collaborative learning produced in virtual learning communities are being discussed actively in these days. A higher-level interactive tool is essential for successful Internet-based collaborative learning through the network. In this paper, we designed and implemented an integrated browser which has the integrated learning environment to support collaborative learning, and thus the user interface of the network client(News, FTP, HTTP, SMTP, voice text chatting Clients) is improved. Therefore, the educational effect of Internet-based collaborative learning is get closer to that of face-to-face learning.

The Web is a way to share documents and communicate. However, voice and video data can be transmission in real time and currently being developed by the objects and the objects that interact to further develop the Internet. Existing video and audio programs to transmission data to the interface of different types of systems a lot of constraint condition on the cost of the interface, extensibility. In this paper, voice and audio transmission system a different operating system, improve the constraints of the ERP system compatibility and extensibility is a open source based system developed by the research. The program is different types of systems and interface, extensibility with program design and development methodologies, and open source-based system composed This system is good for cost saving and extensibility. Therefore, systems research and development, Extensibility and excellent on the interface, system design and development methodologies, such as real-time video conferencing, HMI, and take advantage of your video available from SNS.
