While this spell gives you no control over the creature, each time it comes into physical contact with  another living being, you can choose to transfer your sensor to the new creature. 

In this way, your sensor can infiltrate a closely guarded area. 

During your turn in a round, you can use a free action to switch from seeing through the current creature’s  eyes to seeing normally or back again.
