MemoryHunt - Mobile App for Hunting the Place of Memories

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.

Applications to Disaster Reduction

10th Anniversary of Tsunami at Banda Aceh, Indonesia (Dec. 2014)

Created by Mahruza Murdani, TDMRC, Syiah Kuala University.

To get an idea of what "MemoryHunt" is, we provide photographs taken at Aceh, Indonesia, to compare photographs after Tsunami disaster to recovery.

This experiment was carried out by Prof. Nishi Yoshimi, and Prof. Yamamoto Hiroyuki at CIAS, Kyoto University as part of Area studies on disaster reponse.

20th Anniversary of Hanshin-Awaji Earthquake (Jan. 2015)

Applications to Tourism

Finding a special viewpoint at a tourist site and taking pictures with the same composition can be used for pilgrimages to sacred sites in anime or tours to find scenes from movies/music. It is also possible to develop the difficulty of taking pictures with the same composition into a game-like activity, such as photo-orienteering.

Tokyo Old Photo Hunting

Find the place of old photos together. The target is Meiji and Taisho Eras in the Photographs (Tokyo) from National Diet Library.

The landscape has changed so much from when the photo was taken about 100 years ago to today that it is sometimes difficult to identify the location just by looking at the current map. For this reason, some old maps can be used as reference maps from the app.

Photographs of Past and Present

Photographs of Past and Present is an example of doing the same thing as the above app with a regular camera. The same thing can be done with a regular camera, but it requires some ingenuity to take pictures while comparing past pictures with the current landscape. Our experience at this time led to the development of a memory hunting app, which in turn developed into the memory graph app.

User Registration

Memory Hunting will start user registration in the future, but for the moment, the system can be used without registration.
