Abstract

A button deck includes a substrate and a two-part non-penetrating pushbutton assembly with an upper portion positioned on an upper surface of the substrate and a lower portion positioned on a lower surface of the substrate. The upper portion includes a button face positioned in a button frame that is coupled to the upper surface of the substrate. The button face is configured to be pressed to move within the button frame toward the upper surface of the substrate. The upper portion and the lower portion are configured to work together to provide a signal to an EGM that the button face has been pressed. The pushbutton assembly is non-penetrating because it does not provide any penetration points through the substrate of the button deck.

First claim

What is claimed is:

1. A button deck for an electronic gaming machine (EGM), comprising:
a substrate having an upper surface and a lower surface; and
a non-penetrating pushbutton assembly, including:
an upper portion positioned on the upper surface of the substrate, the upper portion including:
a button frame coupled to the upper surface of the substrate;
a button face positioned in the button frame and configured to be pressed such that the button face moves within the button frame toward the upper surface of the substrate; and
a plurality of magnets coupled to the button face; and

a lower portion positioned at the lower surface of the substrate, the lower portion including:
at least one electromagnet positioned such that it is aligned with one or more of the plurality of magnets, and
a control board electrically coupled to the at least one electromagnet and configured to:
drive the at least one electromagnet to create a magnetic field;
identify a fluctuation in power required to drive the at least one electromagnet caused by a magnetic field of the plurality of magnets interacting with the magnetic field of the at least one electromagnet when the button face is pressed by a player; and
send a signal to the EGM that the button face has been pressed.

2. The button deck of claim 1 , wherein the upper portion of the non-penetrating pushbutton assembly is coupled to the upper surface of the substrate with adhesive.

3. The button deck of claim 1 , wherein the plurality of magnets comprises at least three static magnets.

4. The button deck of claim 3 , wherein the upper portion:
does not include an overlay with a cutout for the upper portion; and
does not include a cable connecting the upper portion to the lower portion or the EGM.

5. The button deck of claim 1 , wherein the control board is configured to change a force required to press the button face by controlling an intensity of the at least one electromagnet.

6. The button deck of claim 1 , wherein the control board is configured to disable the non-penetrating pushbutton assembly by controlling the at least one electromagnet to reverse the magnetic field to pull the button face into a pressed position.

7. The button deck of claim 1 , wherein the control board is configured to control an intensity and a direction of the at least one electromagnet to provide haptic feedback via the button face and to rattle the button face within the button frame.

8. The button deck of claim 1 , wherein the substrate is a display and the button face comprises a transparent material such that the display is visible through the button face.

9. The button deck of claim 1 , wherein the substrate is a display and the button frame comprises a light diffusing material such that diffused light from the display is visible through the button frame.

10. A method for operating a button deck for an electronic gaming machine (EGM) that includes:
a substrate having an upper surface and a lower surface; and
a non-penetrating pushbutton assembly, including:
an upper portion positioned on the upper surface of the substrate, the upper portion including:
a button frame coupled to the upper surface of the substrate;
a button face positioned in the button frame and configured to be pressed such that the button face moves within the button frame toward the upper surface of the substrate; and
a plurality of magnets coupled to the button face; and

a lower portion positioned at the lower surface of the substrate, the lower portion including:
at least one electromagnet positioned such that it is aligned with one or more of the plurality of magnets, and
a control board electrically coupled to the at least one electromagnet; the method comprising:

driving the at least one electromagnet to create a magnetic field;
identifying a fluctuation in power required to drive the at least one electromagnet caused by a magnetic field of the plurality of magnets interacting with the magnetic field of the at least one electromagnet when the button face is pressed by a player; and
sending a signal to the EGM that the button face has been pressed.

11. A computer program product stored in a non-transitory medium usable to control a button deck for an electronic gaming machine (EGM) that includes:
a substrate having an upper surface and a lower surface; and
a non-penetrating pushbutton assembly, including:
an upper portion positioned on the upper surface of the substrate, the upper portion including:
a button frame coupled to the upper surface of the substrate;
a button face positioned in the button frame and configured to be pressed such that the button face moves within the button frame toward the upper surface of the substrate; and
a plurality of magnets coupled to the button face; and

a lower portion positioned at the lower surface of the substrate, the lower portion including:
at least one electromagnet positioned such that it is aligned with one or more of the plurality of magnets, and
a control board electrically coupled to the at least one electromagnet; the computer program product comprising:

first instructions executable by the control board to drive the at least one electromagnet to create a magnetic field;
second instructions executable by the control board to identify a fluctuation in power required to drive the at least one electromagnet caused by a magnetic field of the plurality of magnets interacting with the magnetic field of the at least one electromagnet when the button face is pressed by a player; and
third instructions executable by the control board to send a signal to the EGM that the button face has been pressed.
