About

Serene Kid

Features
Read full description

It is a small electronic device that works in conjunction with a smartphone (tablet) app. It monitors the child's motor behavior while he or she is watching a favorite cartoon. The Serene KID device analyzes the child's movements, sets an individual criterion for "correct" motor behavior, and controls the viewing of the movie. If the child's motor behavior is normal, the movie runs smoothly. If the child shows excessive motor activity, the screen goes out, briefly depriving the child of the pleasure of watching the movie. Each such daily session lasts 20 minutes. After about a month, the excessive motor activity will disappear, perseverance will appear and attention will become stable. Serene KID is a training device that works automatically and does not require any effort from either the parents or the child. Serene KID does not require any special knowledge and skills. Anyone with a smartphone can use Serene KID. Serene KID - uses the best technologies of behavioral therapy, which managed to "embed" in a microprocessor device. The essence of Serene KID technology is to accelerate the development of brain mechanisms that inhibit excessive excitation and control behavior. The technology is based on the development of natural brain mechanisms and does not use any physical influences. The technology utilizes the child's natural desire for entertainment.
