Some tablets with a plan of your housse comes with it, on the black ones you can touch anywhere on it and it telepots you there if there isn't already someone at the exact location you touched, on the white ones you can teleport some objects(food from the fridge, phones and electronics, etc.) to you. Each member of the family as one of each tablet. Each of'em can put some restrictions on the others teleportation Ex: lock your own room so other people don't teleport in there. In the settings of the tablet you can choose where it will respawn if gets too far away(about 500m)from that location.
