The paper reports an experimental study that was carried out in Manaus (Amazonas, Brazil) with the participation of eight visually impaired athletes on 100 m sprint Paralympic races. A trajectory correction system was used, based on an accelerometer and a gyroscope for motion detection, an algorithm to track the athlete's trajectories and a haptic actuator for the interaction with the athletes. The experimental results show the relevance in the use of this type of systems in Paralympic 100 m races for visually impaired athletes, mainly with the purpose of increasing their autonomy by mimicking their guides.
