Life-reading eyes / Analize aura and invisibility

[Atracious]

Hey, I recently noticed the Life-Reading Eyes on d20pfsrd and was wondering how they/the analyze aura spell they use would interact with invisible creatures.

I feel that if I have it on the magic aura mode I would see as per arcane sight.
Health mode would be as per the shaman's life spirit hex Life Sight.
Emotions would show any living creature unless under mind blank.
And alignment aura mode would only show if a creature had an alignment aura ability.
Any help would be appreciated.

Target one creature or object

so you need to be able to target an invisible creature, normally you cant target creatures you cant see. Cant see a creature,then you cant target the creature
