Haptic communication system using cutaneous actuators for simulation of continuous human touch
摘要
說(shuō)明書
The haptic communication system may include cutaneous actuators 108 that transmit information related to social touch to the body 112 when a user is sending the information (i.e., the user is now a sending user). The cutaneous actuators 108 may be positioned on the array 100 to provide vibratory feedback when another user sends a haptic communication to the body 112 of the sending user. In embodiments, one actuator may induce a feedback vibration, while another actuator creates a second vibration to suppress the first from propagating to unwanted regions of the body 112 or array 100 to localize the haptic experience, as described below in detail with reference to
In embodiments, the cutaneous actuators 108 may be one or more of voice coils, linear resonant actuators (LRAs), eccentric rotating mass actuators, piezoelectric actuators, electroactive polymer actuators, shape memory alloy actuators, pneumatic actuators, microfluidic actuators, and acoustic metasurface actuators. A voice coil includes a former, collar, and winding and provides motive force to the body 112 of the user by the reaction of a magnetic field to current passing through the coil. An LRA uses a voice coil and AC input to produce a vibration with a frequency and amplitude corresponding to an electrical signal. An eccentric rotating mass actuator uses the magnetic field of a DC current to move a small rotating mass to produce lateral vibration. A piezoelectric actuator produces a vibration corresponding to an AC current applied to it.
In embodiments, the haptic output produced by the cutaneous actuators 208 may include information on one or more of pressure, temperature, texture, sheer stress, time, and space.
