This should get you started: 

#! perl -slw
use strict;
use Term::ReadKey;

while( 1 ) {
    my $key = ReadKey 0.1;
    print 'Got: ' , defined $key ? "'$key'" : ' nothing!';

}
__END__

c:\test>"ReadKey(Term).pl"
Got:  nothing!
...
Got:  nothing!
Got: ' '
Got:  nothing!
...
Got:  nothing!
Got: 'v'
Got:  nothing!
Got:  nothing!
Got:  nothing!
Got: 'V'
Got:  nothing!
...
Got:  nothing!
