My grandmother has dementia. It made me realise how easily a family can keep a photograph and lose the story behind it. I built Trace & Tell for the person in a family who looks after the photos and wants to ask about them while someone still remembers. Choose a detail in a photograph, put a question into your own words and print it to take to a relative. Afterwards, save their answer beside the photograph in a small family exhibit. “I don’t remember” can stay in their own words, too. Each exhibit links back to the photograph and the exact question they answered. If that question changes later, the app preserves the earlier wording and flags the exhibit for review. The demo uses historical photographs, recorded model responses and clearly labelled fictional recollections.
