Dementia is an incurable mental condition that is suffered by 749,000 Koreans. That number is expected to rise to over 3 million by 2050. It is emotionally difficult when a loved one is afflicted, and children who witness this suffer the most as parents lack ways to help them understand. We wanted to empower families help kids cope, while increasing understanding about the condition so that they can recognize its symptoms and get early treatment. Working with experts in child psychology, we authored a fairy-tale entitled “Who Sprinkled Salt on My Cake?” and created it with a magical Augmented Reality technology that made children interested and understand about dementia easily. Total 30,000 copies of the book were distributed to children throughout Korea via almost 400 schools and libraries.
