A recognition result determination section determines whether or not a character string identified by a speech recognition section through a speech recognition process includes a desire type character string (non-specific instruction type operation character string) in which an object to be operated is not specified. Further, a request level determination section determines a request level related to the desire type character string by detecting a change in sound pressure level on the basis of a speech signal. When the recognition result determination section makes a positive decision, a level-based instruction execution section specifies the object to be operated and gives a predetermined operation instruction on the basis of a content of the desire type character string and a request level determination result.

Speech recognition with request level determination

An operating device for operating at least one vehicle electronic device includes an image display device connected to the vehicle electronic device, a controller including an input device for operating the electronic device, and a sensor for detecting one of a touch and an approach of a user at the input device. When the sensor detects one of the touch and the approach of the user at the input device, the image display device displays a predetermined image concerning the input device on a display screen.

Operating device for operating vehicle electronics device

An input device for an information terminal includes an operational experience determining device for determining the operational experience of a user in accordance with the speed of inputting data by the user to a data input screen and a display control device for changing the content on the data input screen in accordance with a result of the determination by the operational experience determining device.
