Generally "industrial" means "industrial strength", or built for a harsh environment, or even "easily cleaned"
It may be large, strong, possibly unattractive.
It may be more of the kind in arcarde games that take a lot of abuse and are less likely to break.
It may be impervious to dust, grease, dirt in general, or liquids, eg "IP67".
So applications?. controlling industrial machinery, arcade where it gets used often and violently, dirty, or even maybe sterile (less likely without more description), cranes, diggers (maybe), steer remote cameras, robotic manipulators.

It may be just the thing for passionate gamers but likely lacking the blue mood lights :)
