Abstract

A haptic signal distribution system capable of distributing haptic synchronous signals includes a master haptic device and groups of slave haptic devices. In one embodiment, the master haptic device is configured to distribute haptic synchronous signals to slave haptic devices. The haptic synchronous signals, for instance, may include information relating to a tempo for a piece of music. A haptic signal distribution system, for example, allows a master wearable haptic device to selectively distribute haptic synchronous signals to one or more groups of slave wearable haptic devices via a wireless communications network. Upon receipt of the haptic synchronous signals, each slave wearable haptic device generates a series of haptic feedback having a rhythm of beats in response to the haptic synchronous signals.

Claims

1-15. -15. (canceled)

16. A method for providing a series of haptic feedback comprising:

generating a first set of haptic signals in accordance with haptic data;

generating a second set of haptic signals in accordance with the haptic data;

transmitting the first set of haptic signals to a first slave wearable haptic device for generating a first series of haptic feedback; and

transmitting the second set of haptic signals to a second slave wearable haptic device for generating a second series of haptic feedback.

17. The method of claim 16, further comprising:

sensing movements of a master wearable haptic device; and

producing the haptic data in response to the movements of the master wearable haptic device.

18. The method of claim 16, further comprising retrieving the haptic data from a storage location in a master wearable haptic device.

19. The method of claim 16, wherein generating a first set of haptic signals in accordance with haptic data further includes adding inaudible temporal synchronization queues in the haptic signals.

20. The method of claim 16, further comprising synchronizing a master clock in the master wearable haptic device and a slave clock in the slave wearable haptic device.
