I mean to ask that we know that resurrection stone brings people nearly back from the death . So how exactly can we interact with a person who is "livelier than a ghost but less than alive"? I mean we can talk and see (partially) the ghosts, but the resurrected persons are more than a ghost. So what are the additional ways we can interact with them?
As you mentioned, you can talk to the resurrected person - as we see when Harry talks to
Lupin, Sirius, and his parents.
You can see the person you called back - they're not just a disembodied voice.
(This part is probably what answers your question the most.)
As we see when Harry summons
Lupin, Sirius, Lily, and James,
the people interact with the world around them -
He knew it had happened, because he heard slight movements around him that suggested frail bodies shifting their footing on the earthy, twig-strewn ground that marked the outer edge of the forest.
