You can also put your STDIN read into a thread. Here is an example where each key is detected, but you can write it more simply if you are willing to let STDIN to be line buffered, where the line comes in only after you hit a Return. 
#!/usr/bin/perl
use warnings;
use strict;
use Term::ReadKey;
use threads;

$|++;

# works non-blocking if read stdin is in a thread
my $thr = threads->new(\&read_in)->detach;

while(1){
print "test\n";
sleep 1;
}

sub read_in{
        while(1){
         my $char;
         if (defined ($char = ReadKey(0)) ) {
            print "\t\t$char->", ord($char),"\n";    
            #process key presses here
            if($char eq 'q'){exit}
            #if(length $char){exit}  # panic button on any key :-)
            }
          }
}

__END__
