Dedicated lap swimmers just have to know their daily distances in the pool. But are they going to concentrate on swimming or counting? Katie Williams, an industrial design grad student at London's Brunel University has come up with a way to relieve them of that choice: Inview smart goggles.
Williams, a former lifeguard, knew that repeatedly checking a wristwatch or wall-mounted pace clock can interfere with a swimmer's stroke. Her goggles incorporate a compass that self-orients when the swimmer enters a pool. It then detects a change in direction that indicates the end of a lap and logs the information. A heads-up display shows the lap count and time elapsed that allow swimmers to chart their performance.
In prototype at present, the commercial version of the package housing the compass and counter will be slightly larger than a quarter and will be attached to the backstrap of the goggles.
