Abstract

Certain example embodiments relate to vending machines with large area transparent touch electrode (LATTE) technology, and/or associated methods. By using the low-E Ag-based coatings described herein, it is possible to create new vending machine user interfaces that are more interesting and interactive than conventional interfaces. Touch-based user interfaces may be useful in vending, attract, and game-playing modes into which example vending machines may be placed and under which they may be operated.

First claim

What is claimed is:

1. A vending machine, comprising:
a cabinet including a plurality of product placement areas;
a window to the product placement areas, the window being connected to the cabinet;
a first transparent multi-layer low-emissivity (low-E) coating supported by the window and patterned into a first set of electrodes, the first set of electrodes being configured to enable all or part of the window to be used as a touch panel configured to accept touch-related inputs to the vending machine; and
processing resources including at least one processor and a memory, the memory comprising instructions that, when executed, are configured to:
receive touch-related operation information corresponding to accepted touch-related inputs, the touch-related operation information being indicative of touch positions and touch types, the touch types including touches of the window, non-touch proximity detections, and gestures; and
control the vending machine to operate in one of a plurality of different operating modes and respond to received touch-related operation information, the different operating modes including product-vending and game-playing modes.

2. The vending machine of claim 1 , wherein touch positions are defined in relation to the product placement areas.

3. The vending machine of claim 2 , wherein touch positions overlap and are coextensive with the product placement areas.

4. The vending machine of claim 1 , wherein the window comprises first and second substantially parallel substrates that are laminated together, the first substrate supporting the first low-E coating, the second substrate supporting a transparent conductive coating that is patterned into a second set of electrodes, the first and second sets of electrodes being configured to enable all or part of the window to be used as the touch panel.

5. The vending machine of claim 4 , wherein the transparent conductive coating is a second low-E coating.

6. The vending machine of claim 5 , wherein the first and second low-E coatings each include a plurality of thin film layers, and wherein the first and second low-E coatings have substantially the same thin film layer structures.

7. The vending machine of claim 4 , wherein the first and second sets of electrodes are configured to enable all or part of the window to be used as a self-capacitance touch panel.

8. The vending machine of claim 4 , wherein one of the first and second sets of electrodes is configured as transmit electrodes and the other is configured as receive electrodes, the first and second sets of electrodes being configured to enable all or part of the window to be used as a mutual capacitance touch panel.

9. The vending machine of claim 8 , wherein the transparent conductive coating is a second low-E coating.

10. The vending machine of claim 4 , wherein the window further comprises optically-clear adhesive.

11. The vending machine of claim 1 , wherein:
the window includes only one low-E coating;
the first set of electrodes is patterned into transmit and receive electrodes; and
the first set of electrodes is configured to enable all or part of the window to be used as a mutual capacitance touch panel.

12. The vending machine of claim 1 , further comprising at least one light source configured to project light onto the window to prompt and/or respond to touch-related input under control of the processing resources and in accordance with the operating mode that is operating.

13. The vending machine of claim 12 , wherein the at least one light source and the first set of electrodes are configured to enable all or part of the window to be used as a projected capacitive touch panel.

14. The vending machine of claim 12 , wherein the processing resources are configured to control the at least one light source to provide a visual indication relative to a given one of the product placement areas, responsive to a detection of touch-related input provided in connection with that product placement area.

15. The vending machine of claim 12 , wherein the processing resources are configured to control the at least one light source to provide a visual indication relative to a given one of the product placement areas to prompt an action to be taken, and/or to indicate an action being taken, relative to the given product placement area, in connection with a game play mode of a game.

16. The vending machine of claim 1 , wherein the processing resources are configured to control the vending machine to vend a product in response to a predetermined series of inputs and/or input types being detected in relation to a given one of the product placement areas using the window as the touch panel, the to-be vended product corresponding to the given product placement area.

17. The vending machine of claim 1 , further comprising a third transparent multi-layer low-E coating supported by the window and patterned into third electrodes, the third electrodes being tuned to receive frequencies from a contactless payment instrument brought into close relative proximity to the vending machine, wherein the memory includes further instructions that are executable to process received frequencies to enable payment for items being vended by the vending machine.

18. A vending machine, comprising:
a cabinet including a plurality of product placement areas;
a capacitive touch panel configured to accept touch-related inputs to the vending machine;
a first glass substrate arranged as a window to the product placement areas, the first glass substrate being connected to the cabinet and forming part of the touch panel;
a first transparent multi-layer low-emissivity (low-E) coating supported by the first glass substrate and being patterned into a first set of electrodes, the first low-E coating including a layer comprising Ag, a layer comprising zinc oxide directly below and in contact with the layer comprising Ag, a layer comprising Ni and/or Cr directly above and in contact with the layer comprising Ag, and at least one silicon-inclusive layer above and at least one silicon-inclusive layer below the layer comprising Ag; and
processing resources including at least one processor and a memory, the memory comprising instructions that, when executed, are configured to control the vending machine to operate in one of a plurality of different operating modes and, in connection therewith, respond to touch-related operation signals received from the touch panel, the different operating modes including product-vending and game-playing modes.

19. The vending machine of claim 18 , further comprising:
a second glass substrate that is substantially parallel to and spaced apart from the first glass substrate, the second glass substrate also forming part of the touch panel; and
a transparent conductive coating supported by the second glass substrate and patterned into a second set of electrodes.

20. The vending machine of claim 18 , further comprising at least one light source configured to project light onto the window to prompt and/or respond to touch-related input under control of the processing resources and in accordance with the operating mode that is operating, wherein the touch panel is a projected capacitive touch panel making use of the at least one light source.

21. The vending machine of claim 20 , wherein the processing resources are configured to control the at least one light source to provide a visual indication relative to a given one of the product placement areas to:
prompt an action to be taken, and/o
