Quick, what’s the point of having a navigation system in your car? To get where you want to be going, right? Well, IBM has another idea: maybe instead of taking you where you want to go, navigation systems should be offering to take you where a paying advertiser wants you to go. Say, right past their shop, for example. Popular Science quotes from one of IBM’s patent applications
Conventional route planning systems determine optimal routes based on different preferred conditions, including minimizing travel time or minimizing the distance traveled. By focusing on optimal route determination, the known route planning systems fail to consider non-optimal routes whose presentation to travelers may have value to other parties.
So, it’s not quite to the point of your nav system saying “I can’t let you not pass a Starbucks, Dave,” but in the future your navigation could strongly suggest that, rather than going to the farmer’s market, you stop by the supermarket that happens to pay IBM the most.
