The role of archives and records centers is expanding, however many potential users are not aware of the importance of the records and archives. As a method to improve the archival information services to users, in this study, we developed chatbot that supports the interaction between the users and the archives and records centers. Thus we examined the specific development procedures and methods, analyzed user requests and questions of the archives and records center of Myongji university as a case, and conducted a logical structure design for chatbot development. After building the chatbot based on IBM Watson Conversation and Kakaotalk messenger, we were able to find how the chatbot interacted with the users through a pilot run. Based on the experience of developing information service chatbot, the implications related the introduction of the chatbot were suggested which include determination of the level of the chatbot, analysis of the user requests, selection of the tool for the chatbot, and syntax setting for the conversational interaction.

Objective: This study aims to draw an efficient UI design by comparing the usability of App drawer and single-layered home screens, which are smartphone home screens. Background: Because smartphone home screen is frequently used including the installation, deletion, and editing of APPs, it should be designed with easily controllable information structure. There is a need to seek a user-friendly UI by comparing the usability of App drawer and single-layered home screens, of which methods to search Apps are different. There is also a need to examine an efficient UI and the factors to improve from the user perspective. Method: This study targeted 30 Android OS and iOS users to evaluate the App drawer and single-layered home screens, of which UI structures are different. Each participant was instructed to carry out an App searching task and App deleting task, and the execution time and the number of errors were measured. After the tasks were completed, they evaluated satisfaction through a questionnaire survey. Results: In the App searching task with low task level, there was no difference in execution level between the App drawer and single-layered home screens. However, the single-layered home screen showed higher efficiency and accuracy in the App deleting task with high task level. As for the group difference according to use experience, there was no difference in satisfaction among Android OS users, but iOS user satisfaction with single-layered home screen with which they were familiar was higher. Conclusion: As for home screen usability, the single-layered home screen UI structure can be advantageous, as task level is higher. Repulsion was higher, when users, who had used easier UI, used complex UI in comparison with user satisfaction, when users familiar with complex UI used easier UI. A UI indicating the current status with clear label marking through a task flow chart-based analysis, and a UI in which a user can immediately recognize by exposing hidden functions to the first depth were revealed as things to improve. Application: The results of this study are expected to be used as reference data in designing smartphone home screens. Especially, when iOS users use Android OS, the results are presumed to contribute to the reduction of predicted barriers.

Multichannel on digital TV not only gave opportunities to the TV audience to view a wide range of programs. but also made it difficult for them to search for the program which they plan to view among over 1000 programs broadcasted on more than 100 channels. In this paper the functions of EPG (Electronic Program Guides) required by the users on digital TV were derived from the systematic analysis of multichannel viewing situations. In the situation analysis the situations where they viewed programs on more than 100 channels were generated systematically and the viewing processes in those situations were analyzed to identify user needs and derive the required functions of EPG. We surveyed the viewing behavior of the audience who subscribed to a digital satellite broadcast. SkyPerfecTV. in Tokyo. Japan. The purpose of the survey was to verify the validity of the functions derived from the situation analysis and to identify hidden user needs which were difficult to in the situation analysis. The functions were implemented on a working prototype of EPG based on a digital TV simulator which broadcasts 500 programs on 100 channels and can be controlled by three working prototypes of personal remote controllers. The working prototype will be used in Participatory Design to make it possible for the users to experience and verify the usefulness of the required functions of EPG and also find problems in user interface design of EPG
