가상 환경에서는 3차원 작업 공간과 3차원 인터랙션이 가능하나, 대부분의 가상현실 애플리케이션은 2차원의 색상 선택기를 사용하고 있다. 본 논문은 가상 환경에서 3차원 색 공간에 기반한 3차원 색상 선택기를 구현하고, 기존 2차원 색상 선택기와 색상 선택 성능을 비교하였다. 3차원 색상 선택기는 3차원 색 공간을 그대로 사용하여 직관적이며, 가상현실 장비인 컨트롤러를 사용하여 색 공간의 특정 지점에 3차원 포인터를 위치시킬 수 있기 때문에, 간단한 사용자 작업으로 색상을 선택할 수 있다. 이에 비해 2차원 색상 선택기는 컴퓨터 환경에서 색상을 다루는 작업을 하는 기존 사용자들에게 익숙하다는 장점이 있으나, 2차원 인터페이스로 색의 속성을 설정해야 하므로 여러 단계의 사용자 작업이 요구되는 단점이 있다. 사용자 실험을 토대로, 가상 환경에서 2차원 색상 선택기 외에 3차원 색상 선택기의 유용성을 확인하였으며, 3차원 색상 선택기를 활용하여 가상 환경에서 자연스러운 3차원 작업을 할 수 있었다.

3D interaction between humans and computers has been possible with the popularization of virtual reality, and it is important to study natural and efficient virtual reality user interfaces. In user interface development, it is essential to analyze and evaluate user factors. In order to analyze the influence of factors on users who use the virtual reality color picker, this paper divides the user groups based on whether they major in art or design, whether they have experience in virtual reality, and whether they have prior knowledge about 3D color space. The color selection error and color selection time of all user groups were compared and analyzed. Although there were statistically significant differences according to the user groups, all user groups used the virtual reality color picker accurately and effectively without any difficulties.

다양한 분야에서 컬러의 중요성이 높아짐에 따라 목적에 맞으면서도 조화로운 컬러들을 선택하는 것도 중요한 일이 되었다. 본 연구에서는 사용자가 다수의 컬러를 선택하고자 할 때, 컬러 선택의 어려움을 줄이고 사용자 만족도가 높은 컬러를 얻는 것을 목표로 하고, 이를 위해 대량의 컬러 데이터를 추출 및 분석하여 사용자들이 많이 사용하여 선호도가 높은 컬러 조합을 반영한 새로운 컬러 추천 인터페이스를 제안하였다. 또한 인터페이스의 효율성과 사용자가 선택한 컬러들에 대한 만족도에 대한 설문조사를 수행함으로써 제안한 인터페이스의 유용함을 평가하였다. 그 결과 기존의 컬러 선택 인터페이스와 비교하여 효율성과 만족도 모두 높은 평가를 받았다.

The purpose of this study is to provide color information in order to planning and merchandising in china fashion through the color of Beijing opera. In objective study, we collect total 302 Beijing opera images. The collecting method of source data is to extract digital color data by color picker. We transform RGB color data to H V/C, CIE L*a*b and analyze the attributes of color and tone, three-dimensional analysis. The results of this study are as follows : 1. The color distrbution of Beijing opera is R(26.9%)>YR(18.2%)>PB(11.6%)>Y(9.6%). Traditional preference color, red is most popular color as 26.7%:, the practice of vivid tone red is numerous. 2. The tone distribution of Beijing opera costume is P(16%)>It(13.9%)>d(11%)>5(9.6%)>4kg (8.2%)>b(7.1%:). The value o# Beijing opera costume distribute medium and medium-high and the chroma of those distributes low. 3. High chroma yellow is restrictive color as the symbol of emperor in china but medium-low chroma yellow is very frequently used. 4. Blue is often used in china costume. Especially in Beijing opera costume blue is symbol of bravery, dignity, cruel character 5. White in Beijing opera costume is much used for symbol of righteous loyalist. Black is less used than white in Beijing opera costume and black is authority color for symbol of the prime minister.

With the advent of the Fourth Industrial Revolution, people need healing. Research in neuroarchitecture shows that people feel happy and stable when working with nature, and patients heal quickly. Therefore, This study aims to quantitatively analyze the colors that help psychological healing in the painting images depicting nature by setting 'Natural Colors' of Biophilic Design as the subject of research. So the purpose of this study was to measure Biophilic Color and to develop Biophilic Color Palette. We extracted Biophilic colors using Impressionist Monet's Landscape painting. After extracting colors using Photoshop Color Picker, we converted RGB color code to NCS color code and Munsell color code. The results of this study were as follows; The ratio of Y was high in the GY-series and YR-series. This is due to the characteristic of impressionism that expresses the change of color by light in close relationship with light. Y is universally considered to be pleasant, representing happiness, sunshine and optimism. Therefore, it is possible to create an environment that helps psychological healing by utilizing the Y-series color palette. Average Blackness was 28. Average Chromaticness was 34.61. The significance of this study is to propose a biophilic color palette that is useful for psychological healing by quantifying the color code of biophilic colors depicted and expressed with adjective images and idiomatic color names. Quantitative and empirical studies on healing colors are needed continuously and should be actively utilized in healing environment planning.
