Abstract: 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.

Abstract: 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.

Abstract: 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.
