This study was conducted to analyze the characteristics of the artificial intelligence chatbot service of the library and compare the usability of the chatbot service applied to the library, and to propose a plan to improve the usability of the artificial intelligence chatbot service in the library. In order to achieve this research purpose, usability comparison factors were extracted through previous studies on the usability evaluation of artificial intelligence chatbot services, and based on case studies, artificial intelligence chatbot services applied to libraries were classified into their own website-based and SNS-based chatbot services according to the platform. Experiments, questionnaires, and interviews were conducted to evaluate the usability of website-based and SNS-based chatbot services applied to the library. Based on the results of the usability evaluation, implications and improvement plans for the artificial intelligence chatbot service of the library were derived.

In this study, we evaluated web usability for hospital web sites in Korea and analyzed the evaluation results of web usability. Estimators investigated twelve hospital web sites and answered a questionnaire. They also performed predefined tasks which were frequently used services in hospital web sites. We had an interview with the estimator for finding what happened in process of evaluating usability. The evaluation results showed that university hospital provided comparatively better web usability for users. But ambiguous and complicated user interface caused confusion among users. The simplifications of service processes and interfaces were necessary to improve web usability. Some hospitals did not offer primary web services and their services related to the tasks were not systematic.

In the case of electronic payment, the obligation to use the certificate-based authentication was abolished. As Fin-tech service providers gain autonomy, various authentication methods are provided. SMS, ARS, PIN, Text-passwords, Fingerprints are popular authentication methods in the mobile Fin-tech services. In this study evaluate the usability and security of authentication methods in a unified mobile environment. We evaluate the usability through SUS and interview. Also we evaluate the security level of authentication methods through NIST guideline. At the result of the usability evaluation, Fingerprint authentication method had been determined as the highest usability, also Fingerprint authentication method had been determined as the safest authentication method by obtaining Security Level 4.

This research is for developing a usability evaluation model based on customer sensation using Quality Function Deployment, which evaluates the relationship between consumer sensation and usability among the physical design factors of dishwashers. Four aspects of the evaluation model; overall sensation factors, detail sensation factors, usability evaluation factors and physical design factors of products were analyzed in three sequential processes of QFD. The sensation evaluation factors and the usability evaluation factors were created from regression analysis of the results of the sensation and usability test. Moreover, thirty-one physical design factors selected through group discussion of ergonomist and manufacturers. Among them, 19 physical design factors according to priority were applied to evaluation model using QFD. With the evaluation model using four aspects, physical design factors influencing user sensation were generated. These factors were 'alarm sound', 'dishwasher size', 'button size' and 'display size'. Consequently, the degree of influences was tested. Design guidelines for dishwashers were derived from finally generated physical design factors.

Currently mobile game market has expanded rapidly due to the development of smart phone. In addition, mobile web board game has been developed consistently. However, several problems appear in users' usability. That is why the user who plays game do not satisfy in aspect with usability. The objective of this research analyses the factors to investigate the efficiency and the accuracy among usability those in web board game based on smart phone. We conduct to research the efficiency and the accuracy in traditional usability literatures and derive the proper usability factors based on smart phone. We expect to provide the guideline related on usability in mobile board game in the future.

Today's mobile devices including smartphones are gradually taking a prominent position in many areas as portable multimedia computers and establishing a new computing paradigm. Nevertheless, it would not be easy for smartphone applications to provide users with a high level of usability under the current environment due to the physical hardware characteristics of each smartphone, which are expected to have a negative impact on the qualities of system, information, and service that smartphone applications provide. Thus, this study examined: 1) the effects of the perceived qualities of system, information, and service of smartphone applications on the perceived usability of the applications, and 2) the effect of the usability on users' individual performance with the given application. A survey was conducted and structural equation modeling (SEM) was used to analyze the data. This study found that there are significant effects of the perceived qualities of system, information, and service of smartphone applications on the perceived usability of the applications. In addition, this study also found a significant effect of the usability of samrtphone applications on the individual performance with the application.

This study is analyzed by comparing the evaluation of usability and study achievement for simulation learning based on Web 3D and VR and it is aimed to verify the characteristics of the virtual reality through a difference in studying effect between each learning method. Therefore, this study is analyzed by comparing the evaluation of usability and study achievement for the CSI Forensics Lab simulation content that has been developed in two learning methods for scientific experiments of DNA analysis with the 75 university students of Life Science as a population(Web 3D=37, VR=38). The results of the study, in usability of user task action, exploratory and navigation, Web 3D simulation learning was positive in a significant difference, but in usability of satisfaction, VR simulation learning was positive in a significant difference. In study achievement, Web 3D simulation learning was slightly higher but did not confirm the significant differences between both of learning.

The purpose of this study was to investigate the improvement of the educational web service by using of usability test. For this purpose, a case study was performed with three teachers. They solved three problems, which were linked to the usability of educational web site, with think-aloud. All their actions in the screen and their verbalizations were recorded as computer files. Recoded data were analyzed with the task-performance time analysis, behavior code analysis, and problem behavior graph analysis. From the result of analysis, five improvement strategies were proposed for the development of EDUNET which is an educational information service system and a national teaching & learning center.
