Touch-sensitive user-interface including configurable virtual widgets
View Patent ↗A touch-sensitive graphical user interface (GUI) may include a touch screen configured to display a graphical user interface including an arrangement of one or more virtual widgets, each virtual widget having a shape and including one or more user interface elements displayed via the graphical user interface. The arrangement of the one or more virtual widgets is configurable. A microcontroller may be configured to sense a touch at the touch screen, identify a virtual widget corresponding with the touch, and initiate an action including at least one of (a) controlling an actuator to provide haptic feedback at an area of the touch screen on which the identified virtual widget is displayed or (b) controlling an electronic device associated with the user interface system.
1. A user interface system, comprising:
a touch screen configured to display a graphical user interface (GUI) including an arrangement of one or more virtual widgets, each virtual widget having a shape and including one or more user interface elements displayed via the GUI;
wherein the arrangement of the one or more virtual widgets is configurable;
an application tool configured to:
parse a GUI definition to identify a plurality of GUI elements in the GUI;
create a record comprising entries of identified GUI elements;
group the identified elements into virtual widgets based on the relative location of the identified GUI elements;
arrange the record of identified GUI elements into a tree-like structure of GUI elements;
collapse identified GUI elements grouped together into virtual widgets into a single collective GUI element in the tree-like structure of GUI elements; and
generate search instructions responsive to the tree-like structure of elements of GUI elements; and
a processor configured to:
sense a touch at the touch screen;
use the search instructions generated by the application tool to identify a virtual widget corresponding with the touch at the touch screen; and
initiate an action including at least one of (a) controlling an actuator to provide haptic feedback at an area of the touch screen on which the identified virtual widget is displayed or (b) controlling an electronic device associated with the user interface system.
2. The user interface system of claim 1 , wherein the processor is embodied in a microcontroller.
3. The user interface system of claim 1 , wherein at least one virtual widget of the GUI comprises an assemblage of multiple active GUI elements, including at least one virtual button, virtual slider, virtual knob, virtual dial, or other virtual user interface.
4. The user interface system of claim 1 , wherein at least one virtual widget of the GUI comprises an assemblage of multiple discrete active GUI elements that collectively define a virtual button, a virtual slider, a virtual knob, a virtual dial, or other virtual user interface.
5. The user interface system of claim 1 , wherein:
the user interface system further comprises a head unit;
the processor is embodied in a touch controller separate from the head unit; and
the touch controller processor is configured to generate and send the head unit a widget message indicating a position or state of the identified virtual widget corresponding with the touch at the touch screen.
6. The user interface system of claim 5 , wherein the widget message sent by the touch controller processor to the head unit indicates at least one of a touch-related position, a rotation, a touched/untouched status, or a number of detected touches on the virtual widget.
7. The user interface system of claim 5 , wherein the touch controller processor is configured to identify a touch-related state of the virtual widget as a function of a detected touch location, touch force, or other measurable aspect of the detected touch on the touchscreen, and wherein the widget message generated by the touch controller processor indicates the identified touch-related state of the virtual widget.
8. The user interface system of claim 1 , wherein the touch screen is configured to selectively display a plurality of different GUI pages, each GUI page including a different set of virtual widgets.
9. A method, comprising:
displaying, at a touch screen, a graphical user interface (GUI) including an arrangement of one or more virtual widgets, each virtual widget having a shape and including one or more user interface elements displayed via the GUI;
wherein the arrangement of the one or more virtual widgets is configurable;
parsing a GUI definition to identify a plurality of GUI elements in the GUI;
creating a record comprising entries of identified GUI elements;
grouping the identified elements into virtual widgets based on the relative location of the identified GUI elements;
arranging the record of identified GUI elements into a tree-like structure of GUI elements;
collapsing identified GUI elements grouped together into virtual widgets into a single collective GUI element in the tree-like structure of GUI elements;
generating search instructions responsive to the tree-like structure of elements of GUI elements;
sensing, by a processor, a touch at the touch screen;
using the search instructions to identify, by the processor, a virtual widget corresponding with the touch at the touch screen; and
initiating, by the processor, an action including at least one of (a) controlling an actuator to provide haptic feedback at an area of the touch screen on which the identified virtual widget is displayed or (b) controlling an electronic device associated with the user interface system.
10. The method of claim 9 , wherein the processor is embodied in a microcontroller.
11. The method of claim 9 , wherein at least one virtual widget of the GUI comprises an assemblage of multiple active GUI elements, including at least one virtual button, virtual slider, virtual knob, virtual dial, or other virtual user interface.
12. The method of claim 9 , wherein at least one virtual widget of the GUI comprises an assemblage of multiple discrete active GUI elements that collectively define a virtual button, a virtual slider, a virtual knob, a virtual dial, or other virtual user interface.
13. The method of claim 9 , wherein:
the processor is embodied in a touch controller separate from a head unit; and
the method comprises:
generating, by the touch controller processor, a widget message indicating a position or state of the identified virtual widget corresponding with the touch at the touch screen; and
sending the widget message from the touch controller processor to the heat unit.
14. The method of claim 13 , wherein the widget message sent by the touch controller processor to the head unit indicates at least one of a touch-related position, a rotation, a touched/untouched status, or a number of detected touches on the virtual widget.
15. The method of claim 13 , comprising:
identifying, by the touch controller processor, a touch-related state of the virtual widget as a function of a detected touch location, touch force, or other measurable aspect of the detected touch on the touchscreen, and
wherein the widget message generated by the touch controller processor indicates the identified touch-related state of the virtual widget.
16. The method of claim 9 , comprising selectively displaying, at the touch screen, a plurality of different GUI pages, each GUI page including a different set of virtual widgets.
