  • Publication number: 20200201442
    Abstract: A gesture recognition result acquiring unit (2a) acquires a gesture recognition result indicating a recognized gesture from a gesture recognition device (11). A voice recognition result acquiring unit (2b) acquires a voice recognition result that is provided by voice recognition of an uttered voice and that indicates function information corresponding to an utterance intention from a voice recognition device (13). A control unit (2d) registers the gesture and the function information in a storage unit (2c) while bringing the gesture and the function information into correspondence with each other, by using the gesture recognition result acquired from the gesture recognition result acquiring unit (2a) and the voice recognition result acquired from the voice recognition result acquiring unit (2b).

  • Publication number: 20180130467
    Abstract: A speech recognition unit recognizes speech within a preset period. A determination unit determines whether the number of utterers in a vehicle is singular or plural. A recognition control unit adopts a recognition result relating to speech uttered after receiving an indication that an utterance is about to start when the number of utterers is plural, and when the number of utterers is singular, adopts a recognition result regardless of whether the recognition result relates to speech uttered after the indication is received or the recognition result relates to speech uttered in a case where the indication is not received. A control unit performs an operation corresponding to the recognition result adopted by the recognition control unit.

  • Patent number: 9410818
    Abstract: According to a navigation device of the invention, at the time of performing turning guidance for a user who drives a vehicle, it is possible to perform the guidance in a way easy-to-understand for the user. Namely, a presentation of a preceding vehicle is made using an actual image or a graphic image of a vehicle that is the same as the actually seen vehicle, so that the user who drives the vehicle in traveling will understand that he/she only has to follow the preceding vehicle actually traveling ahead. This results in such route guidance that does not cause misunderstanding of a turning point and is very easy-to-understand.
