Information presenting apparatus and control method therefor
First Claim
1. A control method for an information presenting apparatus mounted in a vehicle, the method comprising:
- estimating with a processor of the information presenting apparatus whether an emotion felt by a driver of the vehicle is a positive emotion or a negative emotion, based on a physical quantity acquired by a sensor mounted in the vehicle;
identifying with the processor based on information from the sensor whether a line-of-sight of the driver is directed to a frontward direction or a sideward direction, wherein the frontward direction indicates that the line-of-sight of the driver is directed to a front of a road on which the vehicle travels, and wherein the sideward direction indicates that the line-of-sight of the driver is directed to a side of the road;
acquiring with the processor a current road situation on one or more roads outside the vehicle related to the direction of the line-of-sight of the driver when it is identified that the direction of the line-of-sight of the driver is the frontward direction or the sideward direction;
estimating with the processor a sentiment of the driver based ona) the estimated emotion of the driver being the positive emotion or the negative emotion,b) the identified direction of the line-of-sight of the driver being the frontward direction or the sideward direction, andc) the acquired current road situation;
determining with the processor an operation to obtain information for maintaining or modifying the estimated emotion felt by the driver, based ona) the estimated emotion felt by the driver being the positive emotion or the negative emotion,b) the identified direction of the line-of-sight of the driver being the frontward direction or the sideward direction, andc) the acquired current road situation; and
controlling with the processor an output interface of the information presenting apparatus, to present the information for maintaining or modifying the estimated emotion felt by the driver, wherein the information for maintaining or modifying the estimated emotion felt by the driver is obtained by the processor executing the determined operation.

Abstract
A control method for an information presenting apparatus includes: estimating an emotion felt by a user, based on a physical quantity acquired by a sensor; generating identification information that identifies a cause that causes the user to feel the estimated emotion, based on the physical quantity acquired by the sensor or information that a presenter included in the information presenting apparatus presents to the user; and controlling presentation performed by the information presenting apparatus, by using information obtained by executing predetermined processing using the estimated emotion and the generated identification information.

14. A control method for an information presenting apparatus, the method comprising:
-
estimating an emotion felt by a user, based on a physical quantity acquired by a sensor; generating, by a processor, identification information that identifies a cause that causes the user to feel the estimated emotion, based on the physical quantity acquired by the sensor or information presented to the user by an output interface of the information presenting apparatus; and controlling, by the processor, the output interface of the information presenting apparatus, to present information for maintaining or modifying the estimated emotion felt by the user, the information for maintaining or modifying the estimated emotion felt by the user being obtained by executing a predetermined processing using the estimated emotion and the cause identified by the generated identification information, wherein the information for maintaining or modifying the estimated emotion felt by the user includes content different from the information forming the basis for generating the identification information, wherein the cause is a piece of speech data using a first language, the piece of speech data being presented to the user by the output interface through speech output; in the estimating, a degree of understanding indicated by the user about the piece of speech data using the first language presented as the information forming the basis for generating the identification information by the output interface is estimated as the emotion; in the generating, information that identifies the first language of the piece of speech data presented by the output interface is generated as the identification information; in the executing of the predetermined processing, when the estimated degree of understanding is smaller than a predetermined degree, a piece of speech data using a second language different from the first language is obtained as the information for modifying the estimated emotion felt by the user; and in the controlling, the output interface is controlled to present the obtained piece of speech data using the second language through speech output. - View Dependent Claims (15)

16. An information presenting apparatus mounted in a vehicle comprising:
-
a processor; and a memory that stores a program, wherein the program causes the processor to execute; estimating whether an emotion felt by a driver of the vehicle is a positive emotion or a negative emotion, based on a physical quantity acquired by a sensor mounted in the vehicle; identifying, based on information from the sensor, whether a line-of-sight of the driver is directed to a frontward direction or a sideward direction, wherein the frontward direction indicates that the line-of-sight of the driver is directed to a front of a road on which the vehicle travels, and wherein the sideward direction indicates that the line-of-sight of the driver directs to a side of the road and wherein the downward direction indicates that the line-of-sight of the driver directs to a display panel of the information presenting apparatus; acquiring a current road situation on one or more roads outside the vehicle related to the direction of the line-of-sight of the driver when it is identified that the direction of the line-of-sight of the driver is the frontward direction or the sideward direction; estimating a sentiment of the driver based on a) the estimated emotion of the driver being the positive emotion or the negative emotion, b) the identified direction of the line-of-sight of the driver being the frontward direction or the sideward direction, and c) the acquired current road situation; determining an operation to obtain information for maintaining or modifying the estimated emotion felt by the driver, based on a) the estimated emotion felt by the driver being the positive emotion or the negative emotion, b) the identified direction of the line-of-sight of the driver being the frontward direction or the sideward direction, and c) the acquired current road situation; and controlling an output interface of the information presenting apparatus, to present the information for maintaining or modifying the estimated emotion felt by the driver, wherein the information for maintaining or modifying the estimated emotion felt by the driver is obtained by the processor executing the determined operation.
