A navigation system having a travel situation detection function for providing a navigation route of a travel between a start point and an end point includes a storage unit and an inference engine. The storage unit stores a travel purpose determiner that suitably determines a travel purpose according to a travel situation of a predetermined type having time specificity, and the inference engine infers the end point of the travel based on the travel purpose that results from an application of a detected travel situation by the travel situation detection function to the travel purpose determiner.

When a vehicle deviates from a guide route at a first branch point, the state of the first branch point is memorized. Afterward, when a second branch point becomes a target for a route guide and the state of the second branch point is similar to the memorized state, a user of the vehicle is provided with a guide for preventing deviation from the guide route at the second branch point with a manner of the guide changed. This procedure allows learning of tendency of the user with respect to a state apt to cause the user to mistake a guide route. A guide to help prevent a user from deviating from a guide route at a branch point can be thus performed appropriately.

There is disclosed a technique for automatically creating a detailed program table for playing contents according to various conditions. According to this technique, a constraint condition generation unit 103 acquires a condition (constraint condition) related to a user and describes this constraint condition through the use of a constraint condition description function. A constraint condition solution unit 104 carries out constraint solution processing by making reference to content attribute information stored in a content attribute storage unit 124 on the basis of the constraint condition description function supplied from the constraint condition generation unit, thereby deriving an optimal program table (optimal solution) defining a temporal arrangement of a plurality of contents. Moreover, in the case of constraint excess which leads to finding no optimal solution, a constraint condition priority acquisition unit 105 narrows down an optimal program table or performs recalculation while, in the case of constraint shortage which leads to finding a plurality of optimal solutions, a score setting unit 106 narrows down an optimal program table or performs recalculation. On the basis of the optimal program table thus created, a content acquisition unit 109 carries out content acquisition processing and a program playing unit 110 performs playing processing.
