Abstract

A method for providing haptic feedback is provided for a device that produces haptic noise, such as a power tool with an electric motor that produces noises and vibrations while in operation. An environmental condition of the device can be sensed while the device is being operated and generating haptic noise. A haptic noise characteristic of the device can be determined. A haptic drive signal based on the environmental condition and haptic noise characteristic can be generated. The haptic drive signal can be applied to a haptic output device associated with the device.

Claims

1. A vehicle haptic generation system, comprising:

a sensor configured to detect a plurality of vibrations felt by a driver of a vehicle;

a haptic output device configured to provide haptic feedback to the driver in response to a plurality of detected vibrations; and

a haptic output manipulator configured to dynamically adjust a parameter of the haptic feedback based on the plurality of detected vibrations.

2. The system of claim 1, wherein the haptic output device is integrated into a car seat.

3. The system of claim 1, further comprising selecting the haptic feedback based on an environmental condition.

4. The system of claim 3, wherein the environmental condition includes road vibrations.

5. A method of producing a haptic effect using thresholds, comprising:

determining a first haptic perception threshold and a second haptic perception threshold;

detecting a change in an environmental factor as a result of an operation of a device;

updating the first and second haptic perception thresholds based on the change in the environment factor; and

producing a haptic effect that exceeds the first updated haptic perception threshold but is less than the second updated haptic perception threshold.

6. The method of claim 5, wherein the environmental factor associated with the operation of the device comprises an operating temperature of the device.

7. The method of claim 5, wherein the environmental factor associated with the operation of the device comprises an ambient temperature surrounding the device.

8. The method of claim 5, wherein an environmental factor associated with the operation of the device comprises a vibration of the device.

9. The method of claim 5, wherein an environmental factor associated with the operation of the device comprises an amount of sound produced by the device.

10. The method of claim 5, wherein the haptic effect comprises a quantitative and qualitative aspect.

11. The method of claim 5, wherein the first haptic perception threshold is a threshold for perception and the second haptic perception threshold is a threshold for attention breakthrough.

12. The method of claim 5, further comprising a third haptic perception threshold, wherein the third haptic perception is a threshold for a pain.

13. A non-transitory computer readable medium with instructions stored thereon,

when executed by a processor, produces a haptic effect, comprising:

determining a first haptic perception threshold and a second haptic perception threshold;

detecting a change in an environmental factor as a result of an operation of a device;

updating the first and second haptic perception thresholds based on the change in the environment factor; and

producing a haptic effect that exceeds the first updated haptic perception threshold but is less than the second updated haptic perception threshold.

14. The non-transitory computer readable medium of claim 13, wherein an environmental factor associated with the operation of the device comprises an operating temperature of the device.

15. The non-transitory computer readable medium of claim 13, wherein an environmental factor associated with the operation of the device comprises an ambient temperature surrounding the device.
