Incidents of child abduction and loss occur frequently, and each piece of news affects the hearts of people across the country. It also prompts us product developers to make more useful products, hoping to help children and parents. So in what scenarios are children’s watches used? Today we conducted interviews with 20 parents and summarized the following usage scenarios for children’s watches: Children going to and from school: 1)Through children's watches, parents can know the location of their children in real time to ensure that they arrive at school or go home safely. 2)Traveling or large-scale activities: When children travel or participate in large-scale activities, parents can know the child's specific location in real time through the children's watch. If the child gets lost or changes route, parents can also grasp the situation in time. 3)Interest classes and social activities: When children participate in interest classes or other social activities, parents can keep in touch with their children through the watch to ensure their safety. 4)Large playgrounds and crowded places: parents can quickly find their children through kid's watches to avoid being separated due to crowds 5)Emergency: In an emergency, if a child is lost or in danger, parents can immediately contact the child through the watch to provide necessary help and guidance.
