Timothy Kraft, of the University of Alabama at Birmingham (UAB) Vision Science Research Center, is also a competitive target shooter, and he decided to develop a new gunsight that improves marksmanship with intuitive aim:
Opti-sight is a precision-milled half-triangle shape that replaces the traditional pistol gunsight. The design relies on subjective contours, an optics principle that explains how the subconscious mind fills in the blanks when the eye sees half of a familiar shape like a circle, square or triangle, Kraft says.
It looks a lot like the sights on Marko's Steyr pistol, which he graciously let me shoot earlier this year. I've never tried this one, and recall the old saw that fishing lures are designed to catch fishermen. Still, it's an interesting idea.
