This study investigates the user experience about the camera application and the operation environment that share the photographed pictures with the SNS in a smartphone user environment which is a necessity of modern people. To do this, 10 task tasks were selected based on 3 aspects such as manipulation, editing, and sharing, and the task execution time was measured after tasks were performed on 8 persons, 4 persons in 20s. Experiments conducted mainly on Samsung Experience 8 and LG UX 6.0, which are representative user interfaces of Android mobile operating system, showed that there are differences in usability between the three interfaces for each interface. In the course of the experiment, all of the subjects mentioned ease of operation and various functions as advantages. However, the complexity of text-based interfaces has been difficult to use because of the variety of functions that can be set up. Future research will be needed to improve the usability of camera applications by user interface.

Recently, the number of people wishing to return to farming is increasing, However, the lack of farming experience and management information of returnees is one of the main reasons for increasing the probability of agricultural failure. This study proposes an interface to support early facility cultivation management decision-making for returnees who want facility cultivation. The proposed interface is designed with UML(Unified Modeling Language) and provides key decision-making information such as land/crop suitability, land/facility costs, and management costs according to input data such as cultivation areas, selected crops, and cultivation types selected by the user. Through the proposed interface, facility cultivators can effectively and quickly acquire initial decision-making information for facility cultivation in the desired target area.

We propose an intelligent interface algorithm using hand gesture recognition information based on artificial intelligence. This method is functionally an interface that recognizes various motions quickly and intelligently by using MediaPipe and artificial intelligence techniques such as KNN, LSTM, and CNN to track and recognize user hand gestures. To evaluate the performance of the proposed algorithm, it is applied to a self-made 2D top-view racing game and robot control. As a result of applying the algorithm, it was possible to control various movements of the virtual object in the game in detail and robustly. And the result of applying the algorithm to the robot control in the real world, it was possible to control movement, stop, left turn, and right turn. In addition, by controlling the main character of the game and the robot in the real world at the same time, the optimized motion was implemented as an intelligent interface for controlling the coexistence space of virtual and real world. The proposed algorithm enables sophisticated control according to natural and intuitive characteristics using the body and fine movement recognition of fingers, and has the advantage of being skilled in a short period of time, so it can be used as basic data for developing intelligent user interfaces.

본 논문에서는 가속도 센서를 이용한 손가락의 움직임을 인식하는 손가락 동작 인식 장치와 블루투스 통신을 통하여 전송된 손가락의 동작정보를 이용하여 스마트폰에서 문자 입력이 가능한 문자입력 인터페이스를 구현하였다. 중환자실에는 의식은 있으나 말을 못하고, 손을 자유롭게 움직일 수 없는 상태의 환자들에게 의사나 가족과의 보다 나은 의사소통을 통해 스마트폰을 활용한 인터페이스를 개발하여 오진 및 사고를 방지하고 환자의 상태를 이해하는데 도움을 줄 수 있는 환경을 구축하였다.

In this paper, we provide interfaces according to user application environments and provide tools through web-site that users can create interface to apply a wide range of application environment. HTML5 is used in the creation processing, so users can create various interfaces by dragging mouse and apply it to multimedia, game applications as well as documents by using the ASCII code and key events that are provided in the Android OS. Database of interfaces is stored in HDFS (Hadoop Distributed File System) based on Hadoop for management and users can have their own designed interface or select interfaces through simple login any time. In order to provide interface quickly, HIVE based on Hadoop is used for search and the data is provided in XML file which smart mobile can process quickly.

With the emergence of the smart grid era, the interest in green energy which reduce carbon emissions and environment-friendly smart grid which combines the advantages of power and IT technology is increasing around the world. To use the smart grid effectively heterogeneous systems such as EMS, MOS and WIS must be linked together. However, additional interface should be developed to link EMS and heterogeneous systems since IEC has only defines the interface for EMS. Especially, to link legacy system and new system, some software might need to be designed and developed because separate interfaces for connection can be developed depending on each system and environment. In this paper, we propose an integrated interface based on CIM for interconnection between systems. A proposed interface can integrate messages of heterogeneous system and will be able to reduce costs that could be incurred by the removal of the existing system and the addition of the new system.

As the propagation of smart devices has increased and the variety of the devices also has been diversified, various existing functions are concentrated on these smart devices. One of the phenomena is that the paper-book market has partially transferred into an e-Book market. As the demand of the e-Book has increased over time, the improvement of the types of e-Book on the market can be observed. In this study, the usability evaluation on the interface of the e-Book viewer for the types of application, which can be installed in the smart devices, has been conducted. The items for the usability evaluation of the e-Book were defined, the usage patterns were observed objectively and a questionnaire technique was applied. By analyzing the usability evaluation of e-Book interface, the directions for production and improvement of e-Books have been suggested.

Increasingly important UI(user interface) on the digital media era, and increasing awareness about the user experience. In this study, by considering these realities, what impact smartphone UI experience, this product attitudes and purchase intentions you want to check. First, the findings of the smartphone UI experience influence on product attitudes of the smartphone was confirmed. Second, the smartphone's UI experience was confirmed also in the purchase of smartphones that partially affects. Finally, attitudes were identified as affecting the purchase of products for smartphones. The results of this study, the strategies suggest the need for consideration of future marketing strategy for smart phones smartphone's UI experience. Especially valuable experience for the smartphone-focused marketing strategy, such as the administration of post-A/S system, ie, around experience than are necessary. Finally, in order to improve the consumer's purchase decision more than anything that can enhance the positive attitude of consumers for its products marketing strategies are necessary.
