Nail art design system using interactive evolutionary computation with VR

Abstract

In this study, we have developed an interactive design support system with virtual reality (VR) devices. This system automatically creates nail art painting images on a three-dimensional (3D) finger model. A system user can put on a head-mounted display and look at these images in VR space. They can control the 3D finger model in VR space using their hands and observe the nail art designs from various angles. The system provides various nail designs to the user and optimizes the designs according to the user’s evaluation using an interactive genetic algorithm (IGA), which is one of the major methods for interactive evolutionary computation. To build the system, we implemented a tournament-style evaluation method for IGA that we proposed in a previous study. This method provides a simple paired comparison judgment to the user evaluating the candidates. In this system, the candidates are the nail art designs. The nail art design system creates various French nail designs that have different colors with the same basic design. The system allows users to easily and quickly select their favorite design. In the system, the user can choose two different nail art designs, one of which is painted on the 3D finger model on the left hand and the other of which is painted on the rig ht hand. The users can then easily evaluate the candidates by comparing the two designs in detail in VR space.
