Force Sense

"It had to be one of Dooku's minions, of course. And it wasn't always possible to identify other Force-users simply from the impression they left in the Force, only that they were around, but some - some just announced who they were so clearly that they might as well have stood there in the flesh."

- Star Wars: The Clone Wars, Karen Traviss

"I can sense everything going on in that room. Trust me." "It's too risky... besides, your senses aren't that attuned, my young apprentice." "And yours are?" "Possibly."

- Anakin and Obi-Wan, Attack of the Clones

"My son is with them." "Are you sure?" "I have felt him, my Master.""

- Vader and Palpatine, Return of the Jedi

Force Sense is the ability to perceive one's surroundings. The term is broad. One well-known application is sensing the presence of other Force-users, usually (if not exclusively) after prior acquaintance. One might compare it to seeing a crowd of people. Some stand out on their own; some stand out because their faces are familiar.
