The "Chromatic Vision Simulator" has been made Open-Source and the "Chromatic Vision Simulator Android version 3.0" has been released.

8 years have passed since color vision support tool "Chromatic Glass" and "Chromatic Vision Simulator" were released to the world. Meanwhile, throughout the world, understanding of color vision diversity has progressed, and situations where people with color vision feel inconvenience in conducting ordinary living are gradually decreasing.
Today I will be making an announcement that will be a big milestone among my research activities over the last 8 years.

Especially, the "Chromatic Vision Simulator" has been used by more than 470,000 people in over 100 countries and has become a major application. It is also used in school education in countries such as the United States and Germany. However, because of the difficulty of applying color science to practical applications, even after 8 years since the launch of the application, almost no rival apps that have similar performance and the same scientific accuracy have appeared.

I would like to have more people use this technology which will be useful to many people who usually feel inconvenienced by color. From such thinking, I decided to release all the source code of the "Chromatic Vision Simulator" as open source.

In publishing, in order to do it lawfully and without causing annoyance to anyone, I discarded the old source code of the application and rewrote all the code from scratch to match the latest Android devices and OS. And finally, the "Chromatic Vision Simulator Android Version 3.0" is complete.

The source code of this version of "Chromatic Vision Simulator" has been published under MIT license, and as long as people comply with its license terms, they can freely reuse it with almost no restrictions. In the future, everyone can freely add color vision simulation functions to their own software and applications.

In developing this version, I would like to thank my alumni Hirofumi Ukawa and Masataka Matsuda who provided support and guidance with a lot of time and effort, and all my friends who cooperated in testing.
