S-Pencil: A Smart Pencil Grip Monitoring System for Kids Using Sensors

Abstract

Recent advances in sensor technology and ubiquitous computing have sustained them as a better alternative for kids activity monitoring system. This paper presents a system that continuously monitors the proper pencil grip and writing activity of kid using accelerometer and pressure sensors. The system creates a labeled dataset for recognizing the correct location of pencil grip, holding direction of the pencil, and writing activity of kids. The system uses a supervised machine learning technique and labeled dataset for classifying whether a kid properly uses a pencil or not. In addition, a prototype system is developed and adequately tested on real-time user data. The prototype uses accelerometer and pressure sensors for extracting the writing activities. The system uses bluetooth low energy for wirelessly transferring the sensed data of writing activities to the parent and teachers. The system is suitable for kids due to its low cost, small size, and low-power consumption. © 2017 IEEE.
