Younger brother of our CEO is visually impaired. His eyesight started to get worse since he was a student, and it is getting worse everyday. One day, his younger brother said, “I know what building is in Paris, France, but I don’t know what building is in front of my eyes right away. One time, my friend who is also visually impaired took a taxi, and the driver stopped him 30 meters behind his house, and he got off and wandered for two hours.” Our CEO felt that it is truly important for visually impaired to provide location information. So he started to develop a walkway navigation service for visually impaired. Starting from Korea, we did a demo project in Ho Chi Minh district 10 until this March. Now we want to expand our service to the whole of Vietnam.
