Seventy-nine years have passed since the Hiroshima bomb, and the survivors’ number is decreasing due to aging. PLAY SPACE, a peace education organization in Hiroshima is committed to collecting as many stories as possible to promote peace education. However, despite the survivor’s willingness to share their stories, they often experience trauma when recounting their stories. As a small non-profit organization in Hiroshima with limited resources, PLAY SPACE could not afford an extensive amount of budget. We sought a more direct and cost-effective solution to address the problem.

PLAY SPACE has developed a handkerchief device and app that applies the knowledge of certified psychologists and therapists. By converting a handkerchief, which the elderly are accustomed to using into a device, vital data such as heart rate, skin temperature, and perspiration are acquired without causing anxiety to the elderly. The vital data is sent to the interviewer’s smartphone while the AI analyzes and detects the survivor’s mental state. The AI app will select and provide optimal questions (such as questions to calm the survivors when they are upset) or pause the interview if the individual is in an overly tense state and encourage care to recover. This system was developed in collaboration with university psychologists and therapists, incorporating advanced therapeutic techniques accessible to students and others without knowledge. Beyond the testing phase, these systems are currently in active operation.

A method has been developed to collect episodes while providing mental care to traumatized survivors. Through this system, the aim is to gather as many previously untold episodes as possible and utilize them for peace education. Additionally, with media attention for this activation, it challenges the common misconception in Hiroshima that "survivors most talk about their experiences.
