The project ‘New York Story’ is an mobile interactive video for the Big Screen in the IAC building in which people can share their favorite memories of New York with each other. The basic idea of this project is derived from the question, "What is your favorite memory in New York City?" Being in New York, where the world’s culture and art flourishes most, enable people to have exciting memory with enlarging their cultural perception. We intended to collect and share their favorite and unique memories with other people by using everyday mobile device.
