Old Photo Hunting in Kyoto - September 1, 2015 at Kyoto

What is MemoryHunt?

MemoryHunt, or memory hunting, is to find a place of memories using photographs overlayed on the viewfinder of the camera.

It was originally developed to find the place where old photographs were taken. The best way to do this is to try to take exactly the same picture. If you can do this, then the place you take the photo is close to the place where the target photograph was taken. The app can record the location into the metadata so that we can share the photographs on the map.

It is then extended to other applications, especially for recording the change of landscape in disaster affected areas. Overlay of photographs with the current landscape is an effective method for paying attention to the detail of change, and will be useful for refreshing or learning memories of the disaster.
