Smart eyewear for keen swimmers
Smart goggles that help swimmers log laps have been designed by a UK engineering student.
The Inview goggles display a lap count and time elapsed on their lenses so swimmers can track their progress.
Invented by industrial design student Katie Williams, the goggles use an in-built compass to spot when swimmers complete laps.
Ms Williams said the goggles would let swimmers concentrate on improving their strokes rather than count laps.
Small size
Ms Williams said the idea for the Inview goggles came out of her past experiences as a lifeguard at her local swimming pool.
Many keen swimmers rely on a wristwatch or wall-mounted pace clock to keep track of lap times but both change the way that people swim.
"If they have a watch on a lot of swimmers will move their left arm differently, just to see how fast they are going," she said. "It's wasting energy for them really."
Many swimmers also found it difficult to keep track of how many laps they had swum, especially if they were doing a lot of them or were concentrating on getting a stroke perfect, she said.
"I never knew how many I'd swum," said Ms Williams.
The Inview goggles rely on a compass that orients itself when a swimmer first enters the pool. This compass spots when a swimmer changes direction and logs a lap.
The Inview goggles were designed and built for a third-year project on an Industrial Design course at Brunel University.
