Children's playground trampolines are often combined with interactive games, such as setting up interactive projections. Players can interact with virtual game scenes, characters or props during jumping, such as stepping on virtual monsters, planes, etc., and also have a variety of game scenes, such as cities, oceans, forests, etc., which greatly increases the fun and challenge. During the jumping process, children need to constantly adjust their body posture and balance to adapt to the elasticity of the trampoline, which is of great help to improve the body's balance, coordination and reaction ability. At the same time, they can also exercise muscle tissues such as legs, back, and abdomen, promote bone development and strengthen physical fitness. It is a good parent-child interaction platform. Parents can play and compete with their children to enhance their parent-child relationship. In the children's playground, children are also provided with a platform for communication, interaction and competition with other partners, which helps to cultivate children's social skills and teamwork spirit.
