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 encodes features of the temporal envelope 1728 into the carrier signals 1774 by increasing or decreasing a number of the cutaneous actuators 1722 activated proportional to the amplitude (e.g., 1732) of the speech signals. For example, as the amplitude 1732 according to the temporal envelope 1728 increases, the carrier signals 1774 are altered such that the actuator signals (e.g., 1718) activate (turn on) a larger number of the cutaneous actuators 1722 on the haptic communication device 1720. This may result in a larger area of the user's body 1726 receiving stimulation from the haptic vibrations 1724. This may also create a sense of continuous tactile motion (e.g., stroking or moving touch) on the body 1726 rather than discrete actuation points, as described above with reference to FIG. 15B. As the amplitude 1732 according to the temporal envelope 1728 decreases, the carrier signals 1774 are altered such that the actuator signals 1718 activate a smaller number of the cutaneous actuators 1722 on the haptic communication device 1720. Altering the number of cutaneous actuators 1722 activated results in more sophisticated haptic communication effects. The information related to the words of a social touch lexicon described above with reference to FIG. 15B may thus communicated by altering the number of the cutaneous actuators 1722 activated proportional to the amplitude 1732 of the speech signals. By changing the amplitude and patterns of vibration, a large number of combinations, rhythms or messages may be reproduced.
