This issue has come up a few times in my campaigns. I'll call for a Computers check to "scan a planet" or "scan a ship" for more information, and I've had a few players say it should be a Perception check, rather than a Computers check. Another example would be using Perception to search for information within a computer database, rather than specifically use Computers.
My reasoning is that the character isn't exactly looking/listening/tasting/etc. but rather having a computer program do the leg work of physically "scanning" something for more details. Now if the party was physically looking out their viewport windows at something, that'd be a Perception check.
One of the players said that it makes Computers much more powerful if can be used for several types of checks. Their reasoning was that everyone in the Star Wars universe knows how to use a computer, and most skill uses might involve the use of a computer, but actually scanning/searching for something important required the Perception skill. Computers was regulated to slicing mostly.
How are people handling this in their games? My main reasoning for using Computers was that Computers skill checks were listed in the modules for those examples I gave.
