Abstract
The present invention provides an apparatus and system for providing haptic feedback in a user interface. In one embodiment, the apparatus includes a manipulandum, a resistive actuator, and a biasing element disposed between the manipulandum and the resistive actuator. Further, the biasing element is coupled to one of the manipulandum or the resistive actuator and releasably coupled to the housing, the manipulandum or the resistive actuator.
Claims30
An apparatus comprising:
- a manipulandum;
- a resistive actuator configured to output a force to resist movement of the manipulandum;
- and
- a biasing element having a first end and a second end, the biasing element disposed between the manipulandum and the resistive actuator, wherein either:
- the first end is coupled to the manipulandum and the second end is releasably coupled to the housing or the resistive actuator, or the first end is coupled to the resistive actuator, and the second end is releasably coupled to the housing or the manipulandum, and
- wherein the biasing element is configured to be releasably coupled based on receiving a first signal and to output a biasing force substantially simultaneously with the force output by the resistive actuator.
An method comprising:
- providing a manipulandum;
- providing a resistive actuator configured to output a force to resist movement of the manipulandum;
- and
- disposing a biasing element between the manipulandum and the resistive actuator, the biasing element having a first end and a second end, and wherein either:
- the first end is coupled to the manipulandum and the second end is releasably coupled to the housing or the resistive actuator, or
- the first end is coupled to the resistive actuator, and the second end is releasably coupled to the housing or the manipulandum, and
- wherein the biasing element is configured to be releasably coupled based on receiving a first signal and to output a biasing force substantially simultaneously with the force output by the resistive actuator.
A non-transitory computer readable medium comprising instructions, that, when executed, cause a processor to perform the steps of:
- generating a first signal to releasably couple a biasing element with a resistive actuator, a manipulandum, or a housing;
- and
- communicating the first signal to the biasing element, the biasing element configured output a biasing force substantially simultaneously with a resistive force output by the resistive actuator.
