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

Embodiments also relate to a haptic communication system to convey speech messages to a receiving user. A sending user may utter speech sounds or type in a text message into a speech signal generator that generates speech signals corresponding to the speech sounds or the textual message. A temporal envelope of the speech signals is used to convey the speech messages to the receiving user. The temporal envelope represents changes in amplitude of the speech signals. Carrier signals having a periodic waveform are generated and altered using the changes in amplitude of the speech signals to create actuator signals to convey a representation of the temporal envelope to cutaneous actuators. The cutaneous actuators generate haptic vibrations based on the actuator signals. The haptic vibrations represent the speech sounds or textual message that the receiving user is able to understand.

FIG. 17A is an illustration of an example haptic communication system 1700 for envelope encoding of speech signals 1706 and transmission to one or more cutaneous actuators 1722, in accordance with an embodiment. The haptic communication system 1700 includes a microphone 1704, a keyboard 1708, a speech synthesizer 1712, an envelope encoder 1716, and a haptic communication device 1720. In other embodiments, the haptic communication system 1700 may include additional or fewer components than those described herein. Similarly, the functions can be distributed among the components and/or different entities in a different manner than is described here.
