Contactless tactile feedback on gaming terminal with 3D display

1. An electronic gaming machine for providing a game to a player, the electronic gaming machine comprising:

a display having a display surface,

a locating sensor generating an electronic signal based on a player's location in a sensing space, the sensing space including a region adjacent to the display surface;

at least one ultrasonic emitter configured to emit an ultrasonic field when the ultrasonic emitter is activated, at least a portion of the ultrasonic field being located in the sensing space, the ultrasonic field providing a pressure differential detectable by a human hand; and

one or more processors coupled to the display, the locating sensor and the plurality of ultrasonic emitters, the processors configured to:

determine that a game screen provided by the game includes an interface element associated with a contactless feedback effect;

identify a location of one or more player features based on the electrical signal from the locating sensor;

determine a mid-air location to be associated with the interface element associated with the contactless feedback effect based on the identified location of the one or more player features; and

provide an ultrasonic field at the mid-air location that induces a pressure differential at the mid-air location to provide a contactless haptic feedback to the player.

2. The electronic device of claim 1 , wherein determining the mid-air location comprises:

identifying a location that is within a threshold distance of the identified location.

3. The electronic device of claim 1 , wherein determining the mid-air location comprises:

identifying a location that is between the player feature and the display.

4. The electronic device of claim 1 , wherein the game screen includes two or more interface elements associated with contactless feedback effects and wherein determining a mid-air location comprises determining a mid-air location with each interface element associated with one of the contactless feedback effects.

5. The electronic gaming system of claim 4 , wherein determining the mid-air location comprises determining a center point associated with the two or more interface elements and determining mid-air locations that align the center point with the player feature.

6. The electronic gaming system of claim 5 , wherein the center point is aligned with the player feature by placing the center point along a line that is substantially perpendicular to the display and which passes through the player feature.

7. The electronic gaming system of claim 1 , wherein the game screen includes a single interface element associated with a contactless feedback effect and wherein determining the mid-air location comprises determining a mid-air location that is aligned with the player feature.

8. The electronic gaming system of claim 7 , wherein the mid-air location is aligned with the player feature when a line that is substantially perpendicular to the display passes through the player feature and the mid-air location.

9. The electronic gaming system of claim 1 , wherein the mid-air location is a location at which the pressure differential cannot be felt by the player feature unless the player feature is moved from the identified location to a location that is nearer to the display.

10. The electronic gaming system of claim 7 , wherein the mid-air location is less than 10 cm from the identified location.

11. The electronic gaming system of claim 7 , wherein the mid-air location is less than 5 cm from the identified location.

12. The electronic gaming system of claim 1 , further comprising:

determining that the mid-air location has been activated and, in response, updating the game screen.

13. The electronic gaming system of claim 1 , wherein the interface element is a virtual button.

14. The electronic gaming system of claim 1 , wherein determining a mid-air location comprises determining a mid-air location that is located along a line that extends between the player feature and a portion of the display that is used to depict the interface element.

15. A processor-implemented method for providing a game to a player, the method comprising:

determining that a game screen provided by a game includes an interface element associated with a contactless feedback effect;

identifying a location of one or more player features based on an electrical signal from a locating sensor;

determining a mid-air location to be associated with the interface element associated with the contactless feedback effect based on the identified location of the one or more player features; and

providing an ultrasonic field at the mid-air location that induces a pressure differential at the mid-air location to provide a contactless haptic feedback to the player.

16. The method of claim 15 , wherein determining the mid-air location comprises:

identifying a location that is within a threshold distance of the identified location.

17. The method of claim 15 , wherein determining the mid-air location comprises:

identifying a location that is between the player feature and a display.

18. The method of claim 15 , wherein the game screen includes two or more interface elements associated with contactless feedback effects and wherein determining a mid-air location comprises determining a mid-air location with each interface element associated with one of the contactless feedback effects.

19. The method of claim 18 , wherein determining the mid-air location comprises determining a center point associated with the two or more interface elements and determining mid-air locations that align the center point with the player feature.

20. The method of claim 19 , wherein the center point is aligned with the player feature by placing the center point along a line that is substantially perpendicular to the display and which passes through the player feature.
