APSMART of abstract
◦ Solution: An IrDA link based on a serial infrared transceiver has been designed
swimmer’s and implemented for real-time feedback.
◦ Methodology: A wrist-mounted accelerometer provided stroke information to the
transmitter. The signal was detected using a photodiode detector. Both the transmitter
and receiver units measured 27 × 19 mm. Propagation experiments in air and under
water were performed in a glass tank (91 × 39 × 45 cm) to validate the system. The
maximum link length in air was 2 m and in still water 70 cm. In water with bubbles,
the range reduced to 50 wrist cm. This distance is sufficient for –head
communications during swimming.
◦ Conclusion: The information transmitted was the time duration of one complete
stroke, which was updated every stroke and presented to the swimmer using an RGB
LED mounted on the goggles. The hard ware, software and implementation methods
for the IrDA system are described.

Abstract rephrasing
◦
Maintaining a consistent stroke rate is crucial for optimizing swimming performance
and efficiency. Due to Lack of a convenient and waterproof system for real-time
feedback during swimming. By using an IrDA link based on a serial infrared transceiver
has been designed and implemented for real - time swimmer's feedback. A wrist
mounted accelerator provided stroke information to the transmitter and the signal was
detected using a photodiode. The information transmitted was the time duration of one
complete stroke and updated every stroke then presented to swimmer by an RGB LED
mounted on the goggles. Both transmitter and receiver units measured 27x19 mm,
propagation experiments in air and underwater were performed in glass tank (91x39x45
cm) to validate the system. The maximum link length in air was 2 m and in still water 70
cm, in water with bubbles, the range reduced to 50 cm. this distance is sufficient for
wrist - hand communication during swimming. This can lead to better and improved
swimming performance.
