This project aims to develop "Kids activities", a smart bracelet.
It is an interactive health application that targets Childhood obese children (4-12), as it encourages them to move and practice some simple and appropriate sports.
The Smart bracelet interest with an audio guide that engages them to move. The Smart bracelet uses "natural language processing" to make recommendations and implement actions. In addition to the movement sensors that will track the activities and movement of the child.
How does that system work?
In general, The child wears a Smart bracelet. The system will use NLP to interact with the child by asking to do some exercises (such as walking, jumping, ...), or eat healthy foods, and the app will take the response from the kid.The system can sense the movement of kids by using sensors. In addition to creating a weekly record of the child's activity, it is sent to the parents in android app.
