Abstract :
As locks become more and more complex and numerous, locksmiths have less opportunity to practice on and find design flaws with each type of lock. As in other fields, such as dentistry, haptic simulations can provide an alternative form of practice. Lock picking is inherently suited to haptic simulation, as feedback during lock picking is limited to the sense of touch, and the inner workings of locks are intentionally hidden to prevent easy inspection. The technique used to bypass a simple pin-tumbler lock relies on haptic feedback experienced through both hands, with one hand managing a tension wrench and the other hand manipulating a pick. A visual-haptic simulation of pin-tumbler locks that mimics the sensations of lock picking was developed and tested. Experimental results show that haptic training with our simulation enables participants to more quickly pick their first tumbler lock and provides better preparation to pick more difficult locks. Our visual-haptic simulation could be used to provide practice on increasingly difficult locks, and if generalized, could be used to model any number of complex locks on the market, enabling locksmiths and lock-designers to test the security of various locks, or to train apprentices.
