Claim of US Patent No. 9,846,495

1. A human machine interface system for controlling operation of a graphical user interface being displayed by a display module
on a display located in a vehicle, the human interface system comprising:
an interface device operable to control the graphical user interface, the interface device including a knob member and a touchpad,
wherein the knob member is moveable, and the touchpad detects a touch by the user;

an interface operation module controlling the interface device and receiving input data from the interface device in response
to an operation of the interface device; and

a device selection module designating at least one of the knob member or the touchpad as an active device based on a device
selection criteria;

wherein:
the interface operation module transmits data from the knob member to the display module and disregards data from the touchpad
in response to the device selection module designating the knob member as the active device and the touchpad as an inactive
device;

the interface operation module transmits data from the touchpad to the display module and disregards data from the knob member
in response to the device selection module designating the touchpad as the active device and the knob member as the inactive
device; and

the device selection criteria identifies at least one of the knob member or the touchpad as the active device based on at
least one of a movement of the knob or an input touch detected by the touchpad, such that:

the device selection module designates the knob member as the active device and the touchpad as the inactive device in response
to the knob member being moved a distance greater than or equal to a predetermined threshold; and

the device selection module designates the touchpad as the active device and the knob member as the inactive device in response
to the interface operation module recognizing the input touch detected by the touchpad as a valid input.
