FIG. 11F illustrates an example of haptic outputs of different frequencies, according to an embodiment. In addition to the single, two point, and different duration haptic output described above, in other embodiments the haptic output generated by a cutaneous actuator 1104 from a actuator signal 1111 can have a repeating pattern, such as a waveform, with the repetition of the pattern being at different frequencies. FIG. 11F illustrates a low frequency 1131 pattern and a high frequency 1133 pattern. The high frequency 1133 pattern repeats at a higher frequency than the low frequency pattern 1131. In the illustrated example, the duration 1132 of the low frequency pattern is also longer than the duration 1134 of the high frequency 1133 pattern, however, this does not always need to be the case. If the haptic output is a vibration that can be represented as a waveform, then the duration of each pattern in the waveform can be considered a wavelength, and the maximum intensity of the haptic output can be considered the maximum amplitude. Furthermore, although a single maximum intensity level for the haptic output is illustrated for both the low frequency 1131 and high frequency 1133 haptic outputs, in other embodiments the amplitude can be variable and may differ depending on the frequency, and may further differ over time.
