Abstract
A haptic feedback method includes: providing a wearable haptic feedback device comprising one or more bone-conduction haptic feedback units, and driving the one or more bone conduction haptic feedback units with at least a first signal processed using a bone conduction head related transfer function, ‘bHRTF’.
Claims19
A haptic feedback method comprising the steps of:
- providing a wearable haptic feedback device comprising one or more bone-conduction haptic feedback units;
- and
- driving the one or more bone conduction haptic feedback units with at least a first signal processed from an input signal using a bone conduction head related transfer function, ‘bHRTF’, that models how vibrations propagate through human tissue.
A haptic feedback system, comprising:
- a wearable haptic feedback device (54, 802′) comprising one or more bone-conduction haptic feedback units;
- and
- an audio processor (20, 30) adapted to output at least a first signal processed from an input signal using a bone conduction head related transfer function, ‘bHRTF’, that models how vibrations propagate through human tissue, the at least first signal used to drive the one or more bone conduction haptic feedback units.
A haptic feedback method, comprising:
- applying an excitation signal directly to a first location on a head of a user;
- generating, by a first haptic vibration sensor in physical contact with the head at a second location, a first measurement signal of vibrations of the head at the second location caused by propagation of the excitation signal through the head from the first location to the second location;
- deriving a bone conduction head related transfer function from the excitation signal, the first measurement signal, and a measure of the spatial relationship between the first location and the second location on the head;
- providing a wearable haptic device comprising a first bone conduction haptic unit;
- processing the excitation signal using the derived bone conduction head related transfer function to provide an input signal for the bone conduction haptic unit that corresponds to the first measurement signal;
- and
- driving the first bone conduction haptic unit with the input signal to reproduce the vibrations of the head at the second location when the first bone conduction haptic unit is placed in physical contact with the head at the second location.
A non-transitory, computer-readable storage medium containing a computer program comprising computer executable instructions which, when executed by one or more processors of a computer system, cause the computer system to perform actions of a haptic feedback method, comprising:
- driving one or more bone conduction haptic feedback units of a wearable haptic feedback device with at least a first signal processed from an input signal using a bone conduction head related transfer function, ‘bHRTF’, that models how vibrations propagate through human tissue.
