Abstract

A vehicle haptic feedback system includes a haptic actuator, a detection device, and a controller. The haptic actuator is configured to provide haptic feedback to a vehicle driver. The detection device is disposed in an interior of the vehicle and is configured to capture movements of the vehicle driver and output data representing the movements. The controller is coupled to the detection device and is configured to receive a signal from the detection device indicative of the movements. The controller is also coupled to a haptic effect feedback system. Based on the signal, the controller is configured to send a signal to select a haptic effect from an effect table and is configured to send a signal to the haptic actuator to provide the selected haptic effect. The haptic actuator is coupled to a driver'"'"'s seat, a steering wheel, a driver'"'"'s seat belt, and/or an object wearable by the driver.

Claims

1-23. -23. (canceled)

24. A vehicle haptic feedback system comprising:

a haptic actuator configured to provide haptic feedback to a vehicle driver;

a detection device disposed in an interior of the vehicle, wherein the detection device is configured to capture movements of the vehicle driver and output data representing the movements made by the vehicle driver; and

a controller coupled to the detection device and configured to receive a signal from the detection device indicative of the movements, wherein the controller is coupled to a haptic effect feedback system,

wherein based on the signal indicative of the movements, the controller is configured to send a signal to select a haptic effect from an effect table and configured to send a signal to the haptic actuator to provide the selected haptic effect, and

wherein the haptic actuator is coupled to at least one of a driver'"'"'s seat, a steering wheel, a driver'"'"'s seat belt, and/or an object that is wearable by the vehicle driver.

25. The system of claim 24, wherein the movements of the vehicle driver are hand and/or finger movements.

26. The system of claim 24, wherein haptic actuator is coupled to an object that is wearable by the driver of the vehicle, and wherein the object is at least one a pair of gloves, a hat, a necklace, a wrist band, and/or wristlets.

27. The system of claim 24, wherein the haptic actuator is selected from group consisting of electromagnetic motor actuators, eccentric rotating mass, linear resonant actuators, shape memory alloy actuators, electro-active polymer actuators, vibrotactile actuators, inertial actuators, piezoelectric actuators, and moving magnet actuators.

28. The system of claim 24, wherein the detection device is at least one camera.

29. A method of providing haptic feedback to a driver of a vehicle comprising the steps of:

tracking movements of a driver of the vehicle to detect a particular movement by the driver from a table of movements;

selecting a haptic effect from a table of effects based on the detected movement; and

providing the haptic effect to the driver through a haptic actuator,

wherein the haptic actuator is coupled to at least one of a driver'"'"'s seat, a steering wheel, a driver'"'"'s seat belt, and/or an object that is wearable by the vehicle driver.

30. The method of claim 29, wherein the step of tracking movements of the vehicle driver comprises tracking hand and/or finger movements of the driver.

31. The method of claim 29, wherein haptic actuator is coupled to an object that is wearable by the driver of the vehicle, and wherein the object is at least one a pair of gloves, a hat, a necklace, a wrist band, and/or wristlets.

32. The method of claim 29, wherein the haptic actuator is selected from group consisting of electromagnetic motor actuators, eccentric rotating mass, linear resonant actuators, shape memory alloy actuators, electro-active polymer actuators, vibrotactile actuators, inertial actuators, piezoelectric actuators, and moving magnet actuators.

33. The system of claim 29, wherein the step of tracking movements of the vehicle driver comprises tracking movements via at least one camera.
