摘要

A haptic communication device includes an array of cutaneous actuators to generate haptic sensations corresponding to actuator signals received by the array. The haptic sensations include at least a first haptic sensation and a second haptic sensation. The array includes at least a first cutaneous actuator to begin generating the first haptic sensation at a first location on a body of a user at a first time. A second cutaneous actuator begins generating the second haptic sensation at a second location on the body of the user at a second time later than the first time.

說明書

FIG. 8B is a diagram illustrating cutaneous actuators 802A, 802B on a part of receiving user's body 824 (e.g., torso, forearm, leg, head) to generate illusion of actions or motions occurring within the receiving user's body, according to an embodiment. In the embodiment of FIG. 8B, two cutaneous actuators 802A, 802B are located at opposite sides of the user's body part 824. The cutaneous actuators 802A, 802B can be any type of actuators but vibrotactile actuators, such as voice coils and motors, are better adapted to providing these inner body illusions.

By activating the two cutaneous actuators 802A, 802B with a predetermined time interval, the user perceives motions or actions occurring within the user's body part 824 instead of the user's skin. For example, an illusory sensation such as (i) a bullet or projectile entering from a patch of skin and exiting through another path of skin, (ii) a virtual actuator vibrating inside the body part, (iii) a center point of motion moving gradually from one point to another, (iv) saltation occurring inside the body part can be generated. By controlling parameters such as the amplitude, timing and/or sequence of activation, the motion or action inside the user's body part 824 can be emulated.
