Abstract

In a virtual environment, a 3D workspace and 3D interaction are possible, but most virtual reality applications use a 2D color picker. This paper implements a 3D color picker based on 3D color space in a virtual environment, and compares color selection performance with the existing 2D color picker. The 3D color picker is intuitive by using the 3D color space as it is, and it can position the 3D pointer at a specific point in the color space using a controller, which is a virtual reality device, so a user can select a color in one step. On the other hand, the 2D color picker has the advantage of being familiar with existing users who work with colors in a computer environment, but has a disadvantage that requires several steps of user interaction since it has to set color properties through 2D interfaces. Based on user experiments, we confirmed the usefulness of a 3D color picker in addition to a 2D color picker in a virtual environment, and it was possible to perform natural 3D work in a virtual environment using the 3D color picker.

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.
