System and method for controlling haptic devices having multiple operational modes

A processor-readable medium comprising code representing instructions to cause a processor to:

• send a signal to cause a lead-in voltage pulse to be applied to a haptic device, the lead-in voltage pulse configured to cause the haptic device to provide a haptic sensation above a pre-determined sensation threshold within a first predetermined period of time;
• send a signal to cause power to be provided to the haptic device to maintain the haptic sensation above the pre-determined sensation threshold during a second pre-determined period of time after the first pre-determined period of time.

A processor-readable medium comprising code representing instructions to cause a processor to:

• send a signal to cause power to be provided to a haptic device to maintain a haptic sensation provided by the haptic device above a pre-determined sensation threshold during a first predetermined period of time;
• send a signal to cause a stopping voltage pulse to be applied to the haptic device, the stopping voltage pulse configured to cause the haptic device to stop providing the haptic sensation within a second pre-determined period of time after the first pre-determined period of time.

A method, comprising:

• providing steady-state power to a haptic device, the power being configured to cause the haptic device to output a haptic sensation above a pre-determined sensation threshold;
• applying a voltage pulse to the haptic device, the voltage pulse being
• configured to change the haptic sensation output by the haptic device by a predetermined amount within a pre-determined reduced response time.

A method, comprising:

• applying a lead-in voltage pulse to a haptic device, the lead-in voltage pulse configured to cause the haptic device to provide a haptic sensation above a predetermined sensation threshold within a first pre-determined period of time;
• providing power to the haptic device to maintain the haptic sensation above the pre-determined sensation threshold during a second pre-determined period of time after the first pre-determined period of time.

A method comprising:

• providing power to a haptic device to maintain a haptic sensation provided by the haptic device above a pre-determined sensation threshold during a first predetermined period of time;
• and
• applying a stopping voltage pulse to the haptic device, the stopping voltage pulse configured to cause the haptic device to stop providing the haptic sensation within a second pre-determined period of time after the first pre-determined period of time.
