Recently, among smart phone functions, cameras are one of the most popular functions and have become one of the most influential functions for purchasing smartphones. However, the basic camera application of the smart phone has a complicated user environment, which is causing many difficulties for the first time user. In this study, Galaxy S7, which is the newest Galaxy S series among the most used Galaxy S series in Korea, was selected and the usability test of the camera application was limited to shooting and editing sharing functions. As a result, first, improvement of icon graphic and label of text form should be provided at the same time to increase the recognition rate and attention of the icon. Second, it is necessary to simplify the structure and provide an intuitive interface in order to facilitate access to various modes and functions. Third, it is necessary to simplify the provision of personalized customized menus or functions in the development of the camera application because it causes a high failure rate and inconvenience in the special functions which are not widely used.

This study aims to develop an all-fabric integrated smart jacket in order to create a temperature-regulating system based on a user experience design. For this research, previous research technologies of a textile switch interface and a temperature-regulating system were utilized and a unifying technology for the all-fabric integrated smart jacket was developed which can provide the appropriate temperature environments to the human body. A self-heating textile was applied at the areas of the back and hood in the final tested jacket, and an embroidery circuit was developed in the form of a rectangle in the back and in both ears of the hood, taking into account the pattern of the jacket part where it was be applied and the embroidery production method. The textile switch interface was designed in a three-layer structure: an embroidery circuit line in a conductive yarn, an interval material, and a conductive sensing material, and it was made to work with the input and output sensors through the multiple input method. After the all-fabric integrated smart jacket was produced according to the pattern, all of the textile band lines for transmission were gathered and connected with a miniature module for controlling temperature and then integrated into the inside of the left chest pocket of the jacket. After the users put on this jacket, they were asked to assess the wearing satisfaction. Most of them reported a very low level of irritation and discomfort and said that the jacket was as comfortable as everyday clothing.

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.

ISO11783은 농업 산업분야 통신 프로토콜의 국제 표준으로, 농용트랙터 및 작업기 ECU 간의 통신 프로토콜을 표준화한다. 이 표준은 서로 다른 제조사의 제품 간에 호환성을 갖게 하며, 정밀 농업에 대한 핵심 기반을 제공한다. 현재 해외에서는 이미 ISO11783 기반의 AFS(Advanced Farming System)를 통한 정밀농업이 상용화되어 농가에 보급되고 있다. 이에 비해, 국내에서 이러한 표준을 따르는 농기계들은 미비한 실정이며, 향후 농업의 정밀 농업화를 통한 고부가가치 창출 및 선진국의 무역 장벽에 대비와 해외 수출 판로 개척을 위해 ISO11783 표준에 대한 R&D가 필요로 한다. 이에 IsoAgLib를 분석하고 임베디드 보드에 Porting하여 ISO11783 기반 작업기 ECU를 구현하였고, 이를 기반으로 ISO11783 기반 작업기 ECU의 구현 방법을 발표한다. IsoAgLib의 시스템 아키텍처는 계층화 되어 있어, 타겟에 의존적인 계층만 수정하여, IAR 환경에서 Cortex M3 보드에 포팅을 완료하였다. 작업기 ECU들은 자신만의 인터페이스 화면을 갖으며, 이를 Object pool이라 한다. 이것을 Virtual Terminal(VT)에 업로드 하여, VT가 해당 작업기 ECU의 사용자 인터페이스 기능을 제공하도록 한다. 이에 작업기 ECU 구현 1 단계로, 'VT-Designer'를 통하여 Object pool를 설계한다. 2 단계, 'vt2iso'를 통해서 Object pool을 IsoAgLib 상에서 사용할 수 있도록 변환한다. 3 단계, 포팅된 IsoAgLib project에 변환된 파일을 포함 시킨다. 4 단계, 작업기 ECU의 주기적인 작업 및 각 메시지 수신시 수행할 작업을 코딩한다. 5 단계, 빌드 및 타겟 보드에 업로딩 한 후, New Holland 사의 $Intelliview^{TM}$ iv display (VT)과 연결하여 동작을 확인한다. 확인 결과로 VT에 디자인한 Object pool이 표시 되며 soft key 입력 시 작업기 ECU에서 LED가 변한다. 결론적으로, 연구 결과를 바탕으로 ISO11783 기반의 작업기 ECU의 디자인 및 구현이 가능하며, 이를 통해 향후 국내의 ISO11783 기반의 작업기 ECU의 개발에 도움을 줄 수 있다.

This study aimed to understand the sex differences in cognitive behaviors in website design and demonstrate a practical basis for utilizing these differences into more user-centered design concept. Especially, we focused on the sex-different preference according to the information architecture of website navigation. First, We investigated general differences between men and women in cognitive behaviors through various literature studies. According to our investigation, men's cognitive works generally tend to follow a regular sequence and proceed step by step. On the other hand, women's cognitive style is generally characterized by random generation and simultaneous progress. To examine that these differences can be found in use of website navigation, we made an experiment in website design. We designed several test websites that have same contents but different style of navigation structure. A similar number of men and women were chosen for this test and they implemented given tasks. During the test, participants reported their preference on each websites and their implementing time and number of errors were collected. Based on the analysis of test data, it was possible to conclude that male participants' preference for the navigation with a narrow and deep information structure is relatively higher than female participants' preference for the same navigation, On the other hand, female participants have a preference of the navigation with a broad and swallow information structure. The result of study showed that there is a close correlation between the sex differences in preference of navigation types and the general sex differences in cognitive behavior. This finding can be used as a basis for designing the website navigation in which sex differences are reflected.
