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 actuator signal generator 1776 decomposes the speech signals 1706 into frequency bands. For example, an array of band-pass filters that span the speech spectrum may be used to decompose the speech signals 1706 into the frequency bands. The actuator signal generator 1776 extracts a corresponding temporal envelope (“ENVi”) from each frequency band Fi. Each corresponding temporal envelope ENVi represents changes in amplitude (e.g., 1732) of the frequency band Fi. The actuator signal generator 1776 generates the actuator signals 1718 by encoding changes in the amplitude of the frequency band Fi from each corresponding temporal envelope ENVi into the carrier signals 1774.
