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

The Contemporary paradigm to understand the complexity and diversity is moving to 'Becoming' that taken place in reviewing at the relation of various concepts. In Japan, After the collapse of modern architecture has been declared 'Metabolism' was appeared. They tried to apply organism's metabolic system to buildings based on ecological thoughts. But Metaboilsm's projects had revealed limitations of representation that the city on the mechanical system became a huge scale. As a result, It caused a break the cultural context of the region in Japan. After then, Japanese Architects expressed a pluralistic aspects of modern society for the restoration of disconnected cultural context. From this perspective, The thought of 'becoming' is a new role for Contemporary Japanese Architect. This research is focused of projects of SANAA, Ito Toyo, Sou Fujimoto, because they have spatial thought about realizing the space through the ways organizing the various potential possibilities in the simple external form not stimulated. They are realize the 'becoming-space' within the architecture. This 'becoming-space' gives people in building the new characteristics and experience that potential interactions among user, architecture and nature. It is non-representational space not fixed, but changing organically and variably.

Recently, museums are attracting the attention of visitors and society. However, research on museum interpretation conducted at domestic and foreign is relatively limited. The plan design of the museum commentary system was mainly based on the perspective of the experts, and most of them do not reflect the desire of the visitors. This study focused on visitors' experience of using museum Interpretation system. Through analyzing the effect of the Interpretation system of the museum that the visitor feels, we examined whether the Interpretation system of the museum meets the cultural needs of the visitors and identified the problems and deficiencies in the system. After that, the problems were rearranged and suggested the main elements of the commentary system of the museum finally, so as to help improve the museum commentary system and the educational function.In the first part of the study, the four major explanatory methods existing in the museum were confirmed. After that, we conducted in - depth interviews on four types of commentary methods and collected existing problems and deficiencies. The results of the type analysis were grouped into 14 types and the questionnaire was used to conduct a general survey on 14 problems. In this study, the user 's discomfort and problems were identified in the museum Interpretation system, and based on this, five key elements necessary for the museum Interpretation system were derived. Among them, inhalation is the weakest element in the museum commentary system, and future research will be conducted on how to apply each factor. I hope that you will be a reference material when you carry out research on the optimization of the Interpretation system of the museum and the improvement of the Interpretation experience.
