The processes and their sequences illustrated in 
The sensation or illusion of motions or actions within a user's body part provided by embodiments described herein may enhance immersiveness of application such as video games. Further, such sensations or illusion may be adopted to widen vocabulary and/or increase bandwidth of haptic communication. Such illusions may produce instructional and directional cues for navigation purposes and object interactions. Inside the body illusion may have medical applications, and could be used to massage the head to reduce headaches and reduce motion sickness and balance disorders.
Haptic Communication System Using Interference of Haptic Outputs
Embodiments also relate to enhancing haptic communication by using two or more cutaneous actuators to create constructive or destructive interference patterns on the receiving user's skin. The actuator signals for the two or more cutaneous actuators are shaped and generated so that the two or more cutaneous actuators cause vibrations on the receiving user's patch of skin to increase or decrease at different locations. In this way, various enhancement to haptic communication including, but not limited to, (i) improved spatial resolution of the vibrations, (ii) creation of virtual cutaneous actuators, and (iii) providing additional encoding schemes for embedding information in the vibrations can be achieved.
