Right direction

A pair of swimming googles has been designed which projects elapsed time and number of laps onto the swimmer's field of vision.  I'm not overly concerned about my times, but it'd be liberating not to have to keep a conscious count of lengths, and I can imagine it being of real use to competitive swimmers in training.

The aspect which impresses me most is the technique by which the device increments the number of lengths.  When the swimmer enters the pool, he/she presses a 'start' button, thereby setting the direction of facing.  A compass in the unit then notes each time the direction changes by 180°.  Elegant simplicity.
