Information providing method and information providing system

An information providing system for providing information for a user who is an occupant of a vehicle, comprising:

• an output equipment for outputting the information;
• an information determining unit for determining information to be provided to the user;
• an information output unit for outputting the information to be provided to the user determined by the information determining unit through the output equipment;
• a user state information acquiring equipment for detecting the user's reaction to the output information;
• and
• an interest level estimating unit for estimating the interest level of the user for the output information based on the user's reaction acquired by the user state information acquiring equipment,
• wherein the information output unit outputs second information which is more detailed information on the first information through the output equipment when the interest level of the user for the output first information is estimated to be higher than a predetermined first threshold, and
• wherein the user state information acquiring equipment detects a line-of-sight direction of the user,
• the information providing system further comprising:
• a visible region extracting unit specifies a visible region visible to the user and an object in the visible region based on the detected line-of-sight direction of the user,
• a user behavior information acquiring unit detects user behavior information on a user's behavior,
• an attention level estimating unit estimates an attention level of the user for each of the object in the visible region based on preference information on the user's preference level accumulated in a database and user information including user behavior information on the detected user's behavior while detecting the user's behavior,
• an attention object specifying unit specifies an attention object which is an object with the highest attention level of the user,
• a confidence level estimating unit estimates a confidence level, which is a magnitude of specification accuracy for the attention object, based on information on the object in the visible region and the user information,
• wherein the information determining unit determines the attention object as a topic and the information on the attention object as the first information, and
• wherein the information output unit outputs the corresponding first information in a form of an output according to magnitude of the confidence level.
