In some malls I have seen these touch screen displays where one can search for and see directions to the store (generic). However, they are very rare, and usually only one per mall, which is appalling. I remember seeing this thing in Kuala Lumpur and that thing - which was placed at several locations inside the mall - even suggests which lift, which stair case, or escalator to take if its on a different floor, and all that from the current location, not a fixed point
