Network and application design for children tracking and identification system with HTML5 and asynchronous communication (Future Kindergarten Project)

The absence of information system which could display condition, actual activity, and annual reporting of kindergarten students in a platform which could be accessed easily anywhere and anytime has led to be a major block between coordination of student, parent, and teacher. One of the most difficult technical implementation is how to compile and display the update of children´s position and activity in a fast (near real-time) duration while accessed from outside communication. Based on these problems, the authors designed and developed a network and application system of tracking and identification module for classroom in the Future Kindergarten Project. This network is consist of series of webcams connected in serial communication with processing unit, where each of them is connected locally with server inside the kindergarten, which can be wiressly accessible from parents. The display of children´s position is done with HTML5 Canvas technology. Data update is done by method of periodic asynchronous communication with server and speeding up the function´s execution time. User interface is developed in a web-basis with a Responsive Design concept. As a result. The web is capable to be displayed in cross-platform (from smartphone to personal computer) with average data update speed up to 254 ms with LAN cable in teacher network configuration and 1154 ms with wireless local access in parent network configuration.
