Abstract: A human machine interface (HMI) system controls operation of a graphical user interface (GUI) being displayed on a display located in a vehicle. The HMI system includes an interface device, an interface operation module, and a device selection module. The interface device is operable to control the GUI and includes a knob member and a touchpad. The interface operation module receives input data from the interface device in response to an operation of the interface device. The device selection module designates at least one of the knob member or the touchpad as an active device based on a device selection criteria. The interface operation module transmits data from an active device to a display module controlling the GUI and disregards data from an inactive device.

Abstract: An apparatus and method for virtual navigation includes a control which controls the dimensional appearance of a first image on a display. The control comprises a second image associated with the first image and a mechanism for altering the appearance of the first image in response to selecting a portion of the second image. The second image is preferably displayed on a display and includes indicia for representing multiple modes of operation. The mechanism for altering the appearance of the first image is preferably a stored program. Alternatively, the mechanism may be implemented in electronic circuitry. An important element of control is the ability to combine indicia which represent different functions into a unitary control apparatus. Each combination of two or more indicia (e.g., direction, speed, incremental or continuous movement, etc.) results in a unique modular and multi-functional control.
