Researchers demonstrate smart gun prototype


Researchers at the New Jersey Institute of Technology moved a step closer to their goal of creating a "smart gun" that can be fired only by its owner, showing off a working prototype at a firing range. The gun relies on biometric sensors in the grip and trigger that can track a gun owner's hand size and strength. The NJIT team, which is working with Australian weapons-maker Metal Storm (which we assume is unrelated to the European headbangers of the same name), claims the prototype identifies gun owners with 90% accuracy.
