The goal of this project is to develop a wearable device that helps hearing-impaired athletes on the field to sense the referee's whistle. In order to achieve this, we have designed and produced a device in wearable form-factor that will not discomfort the users during physical activities.
The device has the capability of real-time signal processing and frequency analysis. Specially designed circuitry conditioning the signals gathered from onboard electret microphone and apply various filtering algorithms. Real-time spectrum analysis to the signals from the microphone carried out with its onboard AVR microcontroller.
Spectrum analysis of 14 different referee whistles carried out and embedded firmware developed according to that data. Four different wearable form factors, wristband, chest band, ankle band, armband, evaluated in the sportsfield conditions.
More than 22 prototype units manufactured and tested on over 120 sportsmen performing in different branches like netball, volleyball, handball, sprint, and athletics. In the direction of the feedback of the sportsmen and their trainers, the design of the device improved in order not to block the freedom of movement.
