A real-time feedback navigation system design for visually impaired swimmers

Abstract

Due to lack of exercise, the visually impaired have a higher risk of developing critical health problems. Among all the sports, the acceptability of swimming is higher for the visually impaired. Swimming can be an excellent exercise for them, for not only maintaining good health, but also improving the illness caused by inactivity’s sedentary. Due to inconvenient, environmental unfriendly, safety concern and some personal obstacle, most of the visually impaired are not willing to swim in public swimming pool. Results showed that the obstacle and unfriendly space are the main reason that affect the willingness of visually impaired to swim. A swimming goggle with real-time feedback navigation system and environmental sensor will be designed to assist, guide direction, reducing obstacles and difficulties of both swimmers and caregivers, providing a convenient way for them to take part in this activity.
