First Claim
1. An apparatus for providing information for vehicle comprising:
- conversation inputting means for inputting contents of a conversation of a user in a vehicle;
speech-recognition means for recognizing the contents of the conversation by using a speech recognition;
keyword extracting means for extracting a keyword to be used for a user'"'"'s interest determination from the contents of the conversation recognized by the speech recognition;
mental condition detecting means for detecting a mental condition of a user when the contents of the conversation is inputted by detecting at least one of a heart rate, a breathing rate and a blood flow velocity of the user, the mental condition being shifted to either a good feeling state or a poor feeling state in speaking;
mental condition quality determining means for determining quality of the detected mental condition,base data accumulating means for handling the result of mental condition quality determination as mental condition information that is linked with the keyword, and for accumulating a pair of the result of the mental condition quality determination and the linked keyword as interest determining base data;
user interest information extracting means for extracting a keyword reflecting a user'"'"'s present interest based on the mental condition information as user interest information from the interest determining base data;
service information collecting means for collecting service information to be served to the user by searching based on the keyword extracted as the user interest information; and
service information output means to output the collected service information in a form of an image, audio, or those combination, wherein;
the mental condition quality determining means includes mental point converting means for converting the mental condition detected by the mental condition detecting means into a mental point which is defined to have a larger numerical value as the mental condition becomes better;
the base data accumulating means accumulates the interest determining base data which is provided by handling the mental point as the mental condition information to be associated and linked with the keyword; and
the user interest information extracting means analyzes a frequency of occurrence of the keyword accumulated in the base data accumulating means, and gives a higher ranking of priority for searching the service information to the keyword which has a higher occurrence frequency and better result of the mental condition quality determination, whereinthe base data accumulating means accumulates only the keyword extracted within a latest predetermined period, and deletes the keyword accumulated for the predetermined period.

Abstract
The apparatus detects a mental condition of a user when a conversation content is inputted. The apparatus further collects service information based on a keyword extracted from conversation and a detected mental condition. For example, a user'"'"'s interest is determined by considering a mental condition, i.e., a user'"'"'s feeling, when the conversation containing the keyword is held. For example, the apparatus provides information collected based on the keyword which the user expresses a good feeling. As a result, it is possible to collect information reflecting the user'"'"'s interest and hobby more exactly from a user'"'"'s conversation in the vehicle. It is possible to provide the apparatus for providing information for vehicles which can respond to a variety of user tastes.
