Development of IoT-Based Data Shoes for Daily Life Step Count

Abstract

© 2018 IEEE. During the past few years, Internet of Things (IoT) has unprecedentedly become a buzz word in most areas of business and industry. In this paper, we have developed an IoT solution for human gait monitoring based on a data shoe system over the internet via 3G/4G LTE or internet router. A private Java application server displays the walking information via graphs and widgets together with Blynk which is a platform on android and iOS mobile apps. To observe gait information, we have adopted force sensitive resistors (FSRs) installed under the insole of the shoes for collecting walking data. ESP8266 Wi-Fi modules were used as low cost data transfer. Bridge widgets function is used for device-to-device communication between both shoes. Step countering, as one of the most important gait parameters, was chosen for evaluating this solution with a simple walking algorithm. The accuracy of step countering is compared to iPhone apps in difference walking styles. The integration of sensors, wireless technology and IoT could improve the data shoe system in terms of facilitating the users and administrators to access the gait monitoring, primarily in the step count.
