We have a working setup. [Wang, Quanxian] Suppose a case. A family has F(father), M(mother), Son(S), Daughter(D) They are all drivers. They have one car with Tizen IVI system. There are 4 seats for driver(front-left), others are customers(Front-right, Back-left, Back-right). Every one has his own account on this Tizen IVI system. Every one maybe the driver and customer.
Today, F is driver, you bind F with front-left display. Tomorrow, M is driver, do you want M use this display, or you want to reconfigure it? Customer or driver is not tizen ivi configure expert. So, the ideal case is that 'Any user who login into the Tizen IVI system should have the chance to select the visible and free displays as he want automatically instead of static binding'. I think I have do full explanation about that. This is just my personal view and hints from my investigation. Thanks everyone to be patient for this long discussion. Wish our Tizen IVI system could be accepted by customer.
