In this project, I used AR (argument reality) technology to create an urban monument, allowing him to float in every corner of the city. This is my response to the trend of media cities-cities that will become part of our interactive medium and serve as a broader connection between strangers. I look forward to inviting the audience to discuss whether we can give virtual objects a special meaning and become our emotional sustenance or information relay. Can they become part of the urban landscape? Effective in bridging the boundary between physical and virtual. I look forward to letting everyone think about the new relationship between us and the city through this project.
