Abstract
A system for producing tactile stimulation includes a processing subsystem. Additionally or alternatively, the system can include a tactile device, input devices, and/or any other suitable components. A method for providing tactile stimulation includes receiving a set of waveform signals associated with a set of transducers; assigning a set of waveform parameters to the set of transducers based on the set of waveform signals; and controlling the set of transducers based on the set of waveform parameters. Additionally or alternatively, the method can include organizing the waveform signals into a set of groupings and/or any other suitable processes.
Claims20
A method for creating mid-air tactile stimulation at a haptic stimulation device comprising a plurality of ultrasound transducers, the method comprising:
- at a processing subsystem of the haptic stimulation device:
- generating a first set of control signals with a first phase value;
- and
- generating a second set of control signals with a second phase value, different from the first phase value;
- and
- at a control subsystem communicatively coupled to the processing subsystem:
- receiving the first set of control signals and the second set of control signals from the processing subsystem;
- and
- transitioning a drive signal for a subset of the plurality of ultrasound transducers from the first set of control signals to the second set of control signals without setting the drive signal to an off state during the transition.
A system comprising:
- a haptic stimulation device comprising a plurality of ultrasound transducers;
- a processing subsystem configured to determine a set of groupings, wherein each grouping comprises a subset of the plurality of ultrasound transducers, wherein determining the set of groupings comprises maximizing a distance between the transducers of each respective grouping;
- and
- a control subsystem communicatively coupled to the processing subsystem, wherein the control subsystem is configured to broadcast a set of control signals to each grouping of the set of groupings.
