  • Vibrotactile device
    Patent number: 12688762
    Abstract: A vibrotactile device and method including an audio signal input unit, manual parameter input unit, microcontroller, vibration motor controller, and at least one vibration motor are provided. The microcontroller is coupled to the audio signal input unit and manual parameter input unit. The vibration motor controller is coupled to the microcontroller and the at least one vibration motor. At least one signal is generated by at least the audio signal input unit or the manual parameter input unit. A modulated signal is generated based, in part, on a filtered signal from the audio signal input unit and a vibration duty cycle is generated, based on a tempo value and a note value of the manual parameter input unit, to generate at least one driving parameter, respectively. The vibration motor controller drives the at least one vibration motor based on the at least one driving parameter.
