A Coaching CMS with Wireless Sensors using ANT+ Connectivity Solution

Abstract

In this paper, a design of Content Management System (CMS) linking up with a mobile device (smartphone, tablet PC etc.) for transmitting, monitoring sensor data and feedback is proposed. The system is intended for fields of sports, rehabilitation promoting health and so forth. Users (athletes, rehabilitants etc.) are equipped with wireless sensors using ANT protocol in addition to the mobile device during training for the purpose of acquiring activity data including biomechanical, physiological parameters and so on. A mobile device buffers sensor data locally and forwards it via wireless network to a web server on the Internet. Simultaneously, the video streaming of activity scenes are recorded from camcorders and forwarded through another transmission line to a streaming service (e.g., Ustream). Principally, the CMS functionality comprises two services. As a synchronous/real time service, the server provides experts (coaches, physiatrists etc.) with analysis and feedback by remote access. In this way, experts are able to analyze the parameters which reflect users’ performance and return the feedback in almost real time. Also for an asynchronous/subsequent service, after training users and experts can replay streaming video linked feedback triggers during the entire training on a time-series plots of the web interface.
