To help Alzheimer’s patients live better with their disease, we developed an app that alerts the patient when a family member is nearby. We use beacon technology to detect the presence of a relative, which means the app can work anywhere offline and even indoors. The alert shows predefined key memories that the patient had shared with the relative and mentions the type of their relationship. This way, the patient will no longer feel uncomfortable or anxious when they don’t recognize their own family members or friends.
