1) normally a living-room has a wide, empty mid-area and "slots" around it, as you can see on the first 4-5 pictures.
2) when you want people to split up, you would design a room in rows, like churches or supermarkets.
3) when you want to lead a (customer) person through a defined route, you would use labyrinth/spiral-style ending at the cashpoint, see picture of the small supermarket (wich is a mess with 2 dead ends when thinking of room-design and customer-psych^^)
4) when you want to give the visitors full freedom in exploring the room, choose a big room divided in different sections by pillars as splitters (see modern malls).
little excursion to room-design.
hope it helps.
