Abstract
Systems and methods for providing haptic feedback at multiple resonance frequencies are disclosed. For example, one disclosed apparatus includes a resonator with a base and a plurality of projections, a first projection of the plurality of projections having a first resonance frequency and a second projection of the plurality of projections having a second resonance frequency, and a piezoelectric actuator coupled to the resonator and operable to output a haptic feedback effect at the first resonance frequency and at the second resonance frequency.
Claims19
An apparatus comprising:
- an input module;
- a resonator comprising multiple resonance frequencies, the resonator configured to output a haptic effect wherein the resonator comprises a plurality of projections;
- and
- a processor coupled to the input module and the resonator, the processor configured to:
- receive an input signal from the input module;
- determine the haptic effect based in part on the input signal, wherein determining a haptic effect based in part on the input signal comprises selecting one of the projections;
- and
- output a haptic signal associated with the haptic effect to the resonator.
A method comprising:
- receiving an input signal from an input module;
- determining a haptic effect based at least on part on the input signal;
- and
- outputting a haptic signal associated with the haptic effect to a resonator comprising multiple resonance frequencies, the resonator configured to output the haptic effect, wherein the resonator comprises a plurality of projections and wherein determining a haptic effect based in part on the input signal comprises selecting one of the projections.
A non-transitory computer readable medium comprising program code, which when executed by a processor is configured to cause the processor to:
- receive an input signal from an input module;
- determine a haptic effect based at least on part on the input signal;
- and
- output a haptic signal associated with the haptic effect to a resonator comprising multiple resonance frequencies, the resonator configured to output the haptic effect, wherein the resonator comprises a plurality of projections and wherein determining a haptic effect based in part on the input signal comprises selecting one of the projections.
