NavSwim is a pair of smart goggles designed for blind swimmers, suitable for daily training and competitions. The system includes goggles and a signal transmitter connected to a suction mechanism, featuring an Inertial Measurement Unit (IMU) and an Ultra Wideband (UWB) module for measuring distance and monitoring athletes' posture in real time. Using artificial intelligence, the goggles provide alerts through vibrations and voice prompts for turns and posture corrections. This technology empowers blind athletes to compete more independently, enhancing fairness and efficiency in competitions.
