BEHAVIOR GUIDING DEVICE, ITS METHOD, ITS PROGRAM AND RECORDING MEDIUM RECORDING THE PROGRAM

PROBLEM TO BE SOLVED: To provide a navigation device capable of guiding movement of a vehicle well. SOLUTION: Curve status in a traveling direction is recognized based on shape data of a front road of the vehicle and size of centrifugal force is operated from a speed of the vehicle. Sound data corresponding to bending of the curve are sound-emitted from a direction side of the curve at an amount of sound corresponding to size of acceleration and centrifugal force. Conversation of an occupant is collected and a word of the conversation is analyzed. When the word of the conversation is same as sound/voice tag corresponding to a direction of the curve, sound-emission is controlled to the state that an amount of the sound of the sound-emitted sound data is decreased in response to the number of conversation and the size of the amount of sound. A driver can confirm the movement state by the conversation action, nap etc. can be prevented and certain safe traveling can be performed. An occupant can confirm the movement state of the vehicle by conversation and action and carsickness can be reduced well. Game feeling can be provided and good movement environment can be provided.
