More than two cutaneous actuators may be employed to create more diverse inner body sensations. FIG. 8C is a schematic diagram illustrating three cutaneous actuators 802C, 802D, 802E for generating sensory illusions of a center point of vibrations in the receiving user's body 824 (e.g., the user's head) moving from point 834A to 834B, according to an embodiment. A first cutaneous actuator 802C is mounted on the top, a second cutaneous actuators 802D is attached to one side of the body part 824, and the last cutaneous actuators 802E is attached to the opposite side of the body part 824. By activating the cutaneous actuators in a certain sequence, the sensation of actions or motions in the user's body part 824 can be generated. For example, by activating cutaneous actuators 802C simultaneously with cutaneous actuator 802D followed by addition vibrations from cutaneous actuator 802E causes the sensation of vibrations to move from a center point 834A between the cutaneous actuators 802E, 802D to another location 834B closer to the cutaneous actuator 802C.
FIGS. 8D through 8G are timing diagrams illustrating the waveforms of actuator signals 830A, 830B applied to two cutaneous actuators, according to embodiments. The actuator signals 830A, 830B are assumed to cause corresponding cutaneous actuators to generate vibrations with approximately the same wave patterns. By modulating the amplitude and/or time of the vibrations at the actuators 802A, 802B, various illusory sensation can be generated.
