What is "AR Mail From Harbin"?

AR Mail from Harbin is a small augmented reality (AR) application that works with a set of postcards. Each postcard is printed with a portion of the plan of St. Sophia, the main church in the center of the city of Harbin. A user can assemble a 3D model of the building by laying out the postcards in the proper composition. By combining a photogrammetric capture of the church, AR technology, and traditional paper media, this tool enhances visitors’ experience at the historical location, increases their understanding of its spatial design, and promotes social interaction between the visitors on site and their friends in remote locations, all in a playful setting.
