  • Patent number: 10943503
    Abstract: A haptic communication device includes a speech signal generator configured to receive speech sounds or a textual message and generate speech signals corresponding to the speech sounds or the textual message. An envelope encoder is operably coupled to the speech signal generator to extract a temporal envelope from the speech signals. The temporal envelope represents changes in amplitude of the speech signals. Carrier signals having a periodic waveform are generated. Actuator signals are generated by encoding the changes in the amplitude of the speech signals from the temporal envelope into the carrier signals. One or more cutaneous actuators are operably coupled to the envelope encoder to generate haptic vibrations representing the speech sounds or the textual message using the actuator signals.

  • Patent number: 10748448
    Abstract: Embodiments relate to enhancing haptic communication by using two or more cutaneous actuators to create constructive or destructive interference patterns on the receiving user's skin. The actuator signals for the two or more cutaneous actuators are shaped and generated so that the two or more cutaneous actuators cause vibrations on the receiving user's patch of skin to increase or decrease. In this way, various enhancement to haptic communication can be achieved.
