Is that a big problem? Why don't the gun owners who perceive that as a problem use the safety or buy a gun with greater trigger pressure? If they don't do those things, why would they want to pay to add this feature?
Gun owner loses concentration for a second. Safe is left unlocked. Child gains access to firearm. Child mimics television and pulls the trigger. Childs hands are too small/weak, firearm is heavy, grip on firearm is frail, gun does not fire.
It's not really a big problem in the grand scheme of things. If you follow the 4 safe behaviors(google it if necessary) it's pretty much impossible to have an accidental discharge.
But mistakes happen (and idiots happen), and occasionally someone has an accidental discharge while handling or cleaning.
I think where this would really shine is for user recognition/unlock as mentioned by a previous poster. There have already been attempts at user recognition, but those relied on magnetic rings or RFID chips.

Or, it can result in more dead people.
Guns that don't go off when the trigger is pulled get people killed.
FWIW, "cleaning their gun" is usually cop for "the family doesn't need the stigma of a suicide ane needs the insurance money if any".
There's also some evidence that a lot of the "kid found a gun" are successful murders (by parents) or, at best, depraved indifference. The families that have them are usually "interesting".
IIRC, the stuff about kids is in Gary Kleck's "Point Blank: Guns and Violence in America" although there was probably some stuff in Philip Cook's "Gun Control".
I stopped reading the research 10-15 years ago, long after it became clear that the research didn't have any effect on people's positions.
The other good source is "Armed and Considered Dangerous: A Survey of Felons and Their Firearms" by Wright and Rossi. They were tasked by the Carter administration with gathering the available research to prove that gun control worked.
