The first cutaneous actuator 1508A may end generating the first haptic sensation (at time t3) after a time interval indicating a duration time of the first haptic sensations. For example, the first cutaneous actuator 1508A may alter a time interval between the first time t1 and the third time t3. The time interval between the first time t1 and the third time t3 indicates the duration time t3?t1 of the first haptic sensation. The smooth continuous motions may be modeled as a function of the duration time t3?t1 of the haptic sensations for stroking motion. The duration time t3?t1 determines the speed of the stroke. The duration time t3?t1 of the first haptic sensation may be increased or decreased to determine which preferred duration time t3?t1 provides better communication of the haptic sensations and words of the social touch lexicon.
In one embodiment, the second cutaneous actuator 1508B may be turned on after the third time t3 has passed, in which case a pause may occur between speakers. Such a configuration may provide other types of haptic communication to the user's body 1500. Again, methods to determine a preferred pause time between the third time t3 and the second time t2 may be implemented similar to the methods described below with reference to
