摘要

A haptic communication device includes an array of cutaneous actuators to generate haptic sensations corresponding to actuator signals received by the array. The haptic sensations include at least a first haptic sensation and a second haptic sensation. The array includes at least a first cutaneous actuator to begin generating the first haptic sensation at a first location on a body of a user at a first time. A second cutaneous actuator begins generating the second haptic sensation at a second location on the body of the user at a second time later than the first time.

說明書

In one embodiment, the cutaneous actuators 1722 may be voice coils that convert an analog AC-coupled signal (the actuator signals 1718) to proportional mechanical motion. The cutaneous actuators 1722 may be arranged on a semi-rigid backing that secures them in position against the body 1726 with enough pressure that the haptic vibrations 1724 can be perceived by the user. In other embodiments, the haptic communication device 1720 may include piezoelectric, electroactive polymer, eccentric rotating mass, and linear resonant actuators. Other embodiments of the haptic communication device 1720 are illustrated and described in detail with respect to FIGS. 1, 8B, 8E, 9A-9E, 11A, 11I, 12A-12B, 15A and 16A-16L among others.

FIG. 17B is an illustration of an example temporal envelope 1728 for encoding of the speech signals 1706 and transmission to the cutaneous actuators 1722, in accordance with an embodiment. The signals shown in FIG. 17B include the speech signals 1706, the temporal envelope 1728, and carrier signals 1734.
