Haptic communication system using cutaneous actuators for simulation of continuous human touch
摘要
說明書
The haptic communication system 1800 generates 1884 actuator signals 1818 by encoding the parameters 1852 from the sensor signals 1806 into the broadband carrier signals 1828. In one embodiment, the physical location on the body 1826 of the user that is being actuated may be encoded into the broadband carrier signals 1828. For example, the location of the particular one or more actuators that are driven by the actuator signals 1818 convey information (e.g., identifying a particular phoneme) to the body 1826 of the user. In another embodiment, the amplitude of each frequency component can be used to encode information. In another embodiment, sequences of activation of different actuators can be used to encode information. In another embodiment, features of the power spectrum 1862 can be used.
The haptic communication system 1800 receives 1886 the actuator signals 1818 by cutaneous actuators 1822 communicatively coupled to the broadband signal generator 1816. In one embodiment, the cutaneous actuators 1822 may be voice coils that convert an analog AC-coupled signal (the actuator signals 1818) to proportional mechanical motion. The cutaneous actuators 1822 may be arranged on a semi-rigid backing that secures them in position against the body 1826 with enough pressure that the haptic vibrations 1824 can be perceived by the user.
