Kose develops groundbreaking makeup simulation system

 Kose combines the cutting-edge high-speed projection mapping technology owned by Yoshihiro Watanabe's laboratory at the Tokyo Institute of Technology with the color correction technology developed by the company that can project appropriate colors from the reflection characteristics of the skin. We have developed a realistic make-up simulation system that can


This system has been applied to the make-up simulator "COLOR MACHINE", which has been deployed as a beauty attraction at the concept store "Maison KOSÉ Ginza" since August 17th. The "COLOR MACHINE" will be exhibited at the world's largest technology trade fair "CES 2023" to be held in January 2023.


The company values ​​the diverse beauty that each individual possesses, and also aims to provide color makeup that meets the different needs of each customer. On the other hand, it is not easy to select the one that suits you from among many makeup products, so we aimed to develop a service that allows you to choose the product that suits you more convincingly while enjoying the selection process.

Makeup simulators that run on smartphone apps are known as existing tools to assist makeup selection, but in our research, we focused on projection mapping technology from the idea of ​​creating a more realistic makeup experience using the actual face. In makeup, it is essential to project onto parts that move a lot due to facial expressions, such as the eyes and mouth. In addition, in order to reflect the target color in the makeup, the company developed a color correction technology based on the light reflection characteristics of the skin. By combining these, we succeeded in developing an immersive make-up simulator that can achieve a natural finish as if you were actually applying make-up even on a moving face.

For practical use, the human eye is said to be able to discern discrepancies of about 1/100th of a second, so a system that could follow the movement of a person's face at high speed was required. In order to optimize the high-speed tracking technology possessed by Yoshihiro Watanabe's laboratory at Tokyo Institute of Technology for application in makeup, through joint research, technology that recognizes facial expressions at high speed and graphics that instantly generate makeup images according to facial expressions Improved technology. In addition, in order to achieve high-speed image projection, a special projector that can update the image 1000 times per second was used to achieve natural makeup projection that perfectly follows the movement of the face. In addition, by improving the followability, the makeup does not shift and strong light enters the eyes, making it possible to enjoy makeup without feeling glare.
