Abstract
A haptic device having a plurality of operational modes, including a first operational mode and a second operational mode is provided. The first operational mode is associated with a frequency range. The second operational mode is associated with a frequency range that is different from the frequency range of the first operational mode. A controller is coupled to the haptic device, and is configured to send the haptic device a plurality of control schemes. Each control scheme is uniquely associated with an operational mode from the plurality of operational modes.
Claims40
An apparatus, comprising:
- a haptic device having a plurality of operational modes including a first operational mode and a second operational mode, the first operational mode being associated with a frequency range, the second operational mode being associated with a frequency range being different from the frequency range of the first operational mode, and a third, transitional operational mode associated with a frequency range that lies between the frequency ranges of the first and second operational modes;
- and
- a controller coupled to the haptic device, the controller configured to send the haptic device a plurality of control schemes each being uniquely associated with an operational mode from the plurality of operational modes.
An apparatus, comprising:
- a haptic device configured to provide at least three haptic feedback responses, each haptic feedback response being uniquely associated with an operational mode of the haptic device and with a particular one of first, second and third frequencies, wherein the second frequency is a transitional frequency that lies between the first and third frequencies;
- and
- means for combining the haptic feedback responses based on at least one pre-determined parameter to produce a multi-mode haptic feedback response.
A processor-readable medium comprising code representing instructions to cause a processor to:
- send a first control signal to at least one haptic device collectively having a plurality of operational modes including a first operational mode and a second operational mode, the first control signal being associated with the first operational mode and a frequency range;
- and
- send a second control signal to the at least one haptic device, the second control signal being associated with the second operational mode and a frequency range, the frequency range of the second control signal being different from the frequency range of the first operational mode, the second control signal being different from the first control signal;
- and
- send a third control signal to the at least one haptic device, the third control signal being associated with a third transitional operational mode and a frequency range that lies between the first and second frequency ranges.
A method, comprising:
- producing a first frequency response using a haptic device, the first frequency response being associated with a first frequency range;
- producing a second frequency response using the haptic device, the second frequency response being associated with a second frequency range that is separated from the first frequency range by a transition frequency range that lies between the first and second frequency ranges;
- and
- adjusting a response of the haptic device based on at least one pre-determined parameter to produce a transitional response in the transition frequency range.
A method, comprising:
- sending a first control signal to at least one haptic device collectively having a plurality of operational modes including a first operational mode and a second operational mode, the first control signal being associated with the first operational mode and a frequency range;
- sending a second control signal to the at least one haptic device, the second control signal being associated with the second operational mode and a frequency range, the frequency range of the second control signal being different from the frequency range of the first operational mode, the second control signal being different from the first control signal;
- and
- sending a third control signal to the at least one haptic device, the third control signal being associated with a third transitional operational mode and a frequency range that lies between the first and second frequency ranges.
