In one embodiment, the distance 1516 separating the first cutaneous actuator and a last cutaneous actuator of the array 1502 is less than 15 cm. The distance 1516 between the first cutaneous actuator 1508A and the last cutaneous actuator on the array 1502 is the length of the device 1516 and corresponds to the length of the surface on the body 1500 that experiences the calming or pleasant touches. For example, the length 1516 may be 14 cm along a line of the dorsal forearm 1500. Larger or smaller spacing distances 1512A or lengths 1516 may be used to vary the sensations provided to the user. Different distances 1512A and lengths 1516 may also be used to determine a preferred distance 1512A or length 1516, as described below with respect to 
The array 1502 of the cutaneous actuators may be a one-dimensional array, a two-dimensional array or a two-dimensional pattern having cutaneous actuators spaced unevenly and distributed across the substrate 1504. The array 1502 of the cutaneous actuators may include one or more rows of cutaneous actuators and one or more columns of cutaneous actuators.
