Children are often anxious when faced with a long time on a bullet train, and there are cases of children chasing and crying on the train, leading to other passengers' dissatisfaction. I designed an augmented reality device for children on trains, allowing them to "start their journey early." With windows as the "screen", the virtual content is combined with the location outside the window to form an interactive interface, showing children interesting and informative content, so that the process of riding the train is not boring but meaningful.

High-speed rail is one of the symbols of China's rapid development. With the expansion of the influence and the rapid increase of the number of high-speed rail in China, taking high-speed rail has become one of the preferred modes of transportation for people to travel. At the same time, potential problems in the process of high-speed rail travel also need to be solved. The topic of "children are disgusting on high-speed trains" frequently appears on social media and is widely discussed, but hidden behind the problem is the anxiety caused to children during a long time of high-speed trains. The design of Travel-in is edutainment and fun, so that children will not feel boring on the high-speed rail, and at the same time can get popular science education, which is suitable for the future development trend of Chinese society.
