Abstract

Systems and methods for rendering a haptic effect at a user input element associated with a haptic output device are provided. A primary range and a secondary range of positions are defined for the user input element associated with the haptic output device. In addition, a boundary range of positions is defined for the user input element associated with the haptic output device, the boundary range partially overlapping each of the primary and secondary ranges. A position of the user input element is monitored, and the haptic effect rendered in response to an entry of the user input element to positions within the boundary range.

First claim

We claim:

1. A method for rendering a haptic effect at a trigger user input element, the trigger user input element configured to move in a rotational direction and associated with a haptic output device, the method comprising:
defining a primary range and a secondary range of positions for the trigger user input element;
defining a boundary range of positions for the trigger user input element, the boundary range partially overlapping each of the primary range and the secondary range;
monitoring a rotary position of the trigger user input element;
scaling the primary range, secondary range, and boundary range of positions; and
rendering the haptic effect in response to an entry of the trigger user input element to positions within the boundary range.

2. The method according to claim 1 , wherein the rotary position of the trigger user input element is measured by a potentiometer.

3. The method according to claim 1 , wherein the haptic effect extends a minimum or a maximum range of the trigger user input element.

4. The method according to claim 1 , wherein the position of the trigger user input element is transmitted to a host device as one or more bytes including analog to digital converted data.

5. The method according to claim 1 , wherein the haptic output device is disposed at a peripheral device comprising a controller or a gamepad.

6. The method according to claim 1 , further comprising calculating a normalized position of the trigger user input element.

7. A device comprising:
a processor; and
a memory storing a program for execution by the processor, the program including instructions for:
defining a primary range and a secondary range of positions for a trigger user input element associated with a haptic output device;
defining a boundary range of positions for the trigger user input element, the boundary range partially overlapping each of the primary range and the secondary range;
monitoring a rotary position of the trigger user input element;
scaling the primary range, secondary range, and boundary range of positions; and
rendering a haptic effect in response to an entry of the trigger user input element to positions within the boundary range,
wherein the trigger user input element is configured to move in a rotational direction.

8. The device according to claim 7 , wherein the rotary position of the trigger user input element is measured by a potentiometer.

9. The device according to claim 7 , wherein the haptic effect extends a minimum or a maximum range of the trigger user input element.

10. The device according to claim 7 , wherein the position of the trigger user input element is transmitted to a host device as one or more bytes including analog to digital converted data.

11. The device according to claim 7 , wherein the haptic output device is disposed at a peripheral device comprising a controller or a gamepad.

12. The device according to claim 7 , further comprising instructions for calculating a normalized position of the trigger user input element.

13. A non-transitory computer readable storage medium storing a program configured to be executed by a processor, the program comprising instructions for:
defining a primary range and a secondary range of positions for a trigger user input element associated with a haptic output device;
defining a boundary range of positions for the trigger user input element, the boundary range partially overlapping each of the primary range and the secondary range;
monitoring a rotary position of the trigger user input element;
scaling the primary range, secondary range, and boundary range of positions; and
rendering a haptic effect in response to an entry of the trigger user input element to positions within the boundary range,
wherein the trigger user input element is configured to move in a rotational direction.

14. The computer readable storage medium of claim 13 , wherein the rotary position of the trigger user input element is measured by a potentiometer.

15. The computer readable storage medium of claim 13 , wherein the haptic effect extends a minimum or a maximum range of the trigger user input element.

16. The computer readable storage medium of claim 13 , wherein the position of the trigger user input element is transmitted to a host device as one or more bytes including analog to digital converted data.

17. The computer readable storage medium of claim 13 , wherein the haptic output device is disposed at a peripheral device comprising a controller or a gamepad.

18. The computer readable storage medium of claim 13 , further comprising instructions for calculating a normalized position of the trigger user input element.

19. The method according to claim 1 , wherein movement of the trigger user input element is limited to the primary range when no haptic effect is being rendered.
