More On Gunshot Detection
from the there-are-ears-above-you dept
Joe Schmoe writes in with a link that is basically a followup story to a story we had a few months ago about remote sensors that can be used to detect the location of gunshots. The idea is for police or military uses, but I can see how it could easily be expand in the same way that security cameras work. Forget security cameras, why not get security "ears"? Pop in some voice recognition, and you could catch people on the street just talking about the crimes they plan to commit.

Why stop at sound
We could have smell detectors. Upscale stores of the future could keep the rabble out of the store by locking doors when it detects a stinky person.
Or, to borrow an idea from my cat, how about micro-air-current detectors? Her whiskers seem to detect certain kinds of movement that vision, hearing, or smell cannot.

Or sound generators
I've read some reports that suggest infra-sound (frequencies so low the ear cannot perceive them) can cause heightened emotions in people -- more positive if they are positive, more negative if they are negative. Or it can make people sense a ghostly presence nearby, a "gut feeling" (literally)
Sense of touch is a fascinating thing. We all have hundreds of micro-perceptions of touch that most of us ignore. I'm a contact juggler and feel like I've enhanced this aspect of our existence.

Already used in military
Military humvees already use this tech to determine the origin of incoming fire.
The .50 cal turret uses small mics to pinpoint the source of gunshots. When activated, the system automatically aims the turret and gun towards the sound and fires a few rounds without any manual action taken by the soldier manning the gun.

Re: Already used in military
yeah, and let's hope that there aren't a bunch of nuns taking orphans out on a picnic between the .50 cal and the gunshots, or, for that matter, another humvee
