The conversational agent, which is at the forefront of the 4th industry, aims to personalize the user-centered focus in the future and holds an important position to have a hub that can be connected to various IoT devices. It is a challenge for interactive agents to recognize the user's emotions and provide the correct interaction to personalization. The study first I looked at emotional definitions and scientific and engineering approaches. Then I recognized through social perspectives what social function and what factors emotions have and how they can be used to understand emotions. Based on this, I explored how users can be discovered emotional social factors in communication. This research has shown that social factors can be found in the user's speech, which can be linked to the social meaning of emotions. Finally, I propose a model to discover social factors in user communication. I hope that this will help designer and researcher to study user-centered design and interaction in designing interactive agents.

Starting with 21st Century, the role of the design has been widened and designers began to regard the psychological and behavioral factors as main design considerations. These factors are the core elements especially in designing interactive space. This research proposed the user-centered design methodology for interactive space. It developed Programming Process for Supporting Interactive Behaviors. To compose the process, this research analyzed the influential factors on the interactivity and the results were applied on the process. This newly proposed Programming Process contains four basic stages which are 'Opportunity Identification Cell', 'Intersubject Cell', 'Interaction & Interface Cell', and 'Programming Solution Cell'. More detailed tasks are also specified for each stage. This research asserts that the design process for Interactive space should differ from the past design processes in the fact that it puts much more attention on systemizing the psychological and behavioral elements than before. Therefore the design process for Interactive space should be reinforced with the data related to these psychological and behavioral understandings. The Programming Process of this paper is an attempt to enlarge the roles of these data in designing interactive space, and thus it is an attempt to accommodate the contemporary user-centered design paradigm.

Recently, product design innovation to improve user experience has been perceived as a core element of enterprise competitiveness due to the fierce market competition and decrease of the technological gap between companies, but there is insufficient services to support the product experience evaluation of small and medium-sized companies (SMCs). The aim of this study is to develop a web-based product user experience evaluation and certification system supporting product design practices for SMCs. For system interface design, we conducted systematic functional requirement elicitation methods such as user survey, workflow analysis, user task definition, and function definition. Then main functions, information structure, navigation method, and detailed graphic user interfaces were developed with consideration of user interactions and requirements. In particular, it provides the databases for evaluation efficiency to support the evaluation process above a certain level of performance and efficiency, and knowledge databases to utilize in the evaluation and product design improvement. With help of the developed service platform, It is expected that the service platform would enhance SMCs' product development capability with regard to the user experience evaluation by connecting the consulting firms with SMCs.

In order to complete the AR UI design simply and quickly, the usable factors were studied in this thesis. The primary aim of interface design is to increase the usability. The various factors should be considered together when we evaluate the usability. The idealized usable working model is based on user-centered with the aim of perceiving the interests of users, operating easily and completing targets. In order to ensure the types of usable factors, literature survey method had been used and a total of 85 usable factors had been collected by this survey. To make the usable factors can adapt the augmented reality, the concept of factors should be redefined. We extract the items which is adaptable and user-centered, combine or delete the items that have the same meanings and finally select 25 usable evaluative factors. Then we take HCI professional as the object and collect the data by Heuristic Evaluation. We systematize the usable factors by Principal Component Analysis, and observe the correlation between the usable factors and classify those which have high correlation.

As human-centered design has become new paradigm in the whole field of design, they make an effort to understand users in the field of graphic interface design. However, there are not much of study to systematic process for human-centered approach in graphic interface design. Therefore, in this paper, the study was conducted to develop application methodology of prototype in the graphic user interface design process. The study consists of three sections. first, definition, types and application methods are introduced by secondary research. Second, all the knowledge gathered above by secondary research are integrated in the newly proposed Prototype-based interface design process. There are many types of prototype from idea sketches on the paper to final working prototype realized by computer. It is needed to develop and test appropriate prototype with appropriate techniques by objectives of the stages. Finally, the proposed prototype-base design process is verified and exemplified through the process of using prototype in the development of multi-user educational multimedia product.

Purpose - This study is to integrate organizational factors into UCD process. For this research purpose, we investigated the organizational factors which influence people behaviors in the context of user-centred design practice(UCP). And this study presents organizational culture, organizational learning and change management as the organizational factors. Especially, this study is to investigate how change management influences the relationship between the organizational culture/learning and UCD performance. Research design, data, and methodology - Using the survey methodology with a questionnaire, this study distributed the questionnaire to the experienced 112 practitioners of user-centred design practice in 52 Korean small and medium companies. The organizations differed in range and size from medium-scale, which is under 100 of employees, and to small-scale, which is from 100 to 500. Results - Organizational culture and organizational learning have positive effects on user-centred design practice performance as expected. And change management strengthens the positive relationship between organizational learning and user-centred design practice performance but has no effect on the relationship between organizational culture and user-centred design practice performance. Conclusions - This is the first empirical study of investigating and demonstrating some key organizational factors' relationships and UCD performance of an organization, which will support to institutionalize UCD within an organization, providing theoretical foundations.

Currently, various technological models and services are emerging because of the development of information and communication technology and the convergence of industries. The ICT car field is expanding because of technological convergence in the automobile industry. However, ICT convergence services are still being developed based solely on technology; characterization of users and their needs is lacking. Therefore, two types of ICT car services that apply human-centered design processes are developed in this study. These processes create services and models while considering the quality and functions of products based on users (instead of technology) when developing products or services. Usability evaluation was performed on the developed services; a human-centered design process was applied to the results to confirm that the derived services resulted in high satisfaction. In the future, these research results will provide useful applications when developing ICT car services and strategies.

This research suggests a design process that effectively complements the human-centered design through an objective data-driven approach. The subjective human-centered design process can often lack objectivity and can be supplemented by the data-driven approaches to effectively discover hidden user needs. This research combines the data mining analysis with co-design process and verifies its applicability through the case study on the smart heating jacket. In the data mining process, the clustering can group the users which is the basis for selecting the target groups and the decision tree analysis primarily identifies the important user perception attributes and values. The broad point of view based on the data analysis is modified through the co-design process which is the deeper human-centered design process by using the developed workbook. In the co-design process, the journey maps, needs and pain points, ideas, values for the target user groups are identified and finalized. They can become the basis for starting new product development.
