Claim 14:
15. A method for haptic vibration braking, the method comprising:
at a current time frame, applying a pattern signal, output from a pattern generator, to a haptic vibrator for vibration braking while the haptic vibrator is vibrating;
iteratively setting an amplitude of the pattern signal at the current time frame to a plurality of potential values;
obtaining, using a vibration sensor coupled to the haptic vibrator, a plurality of vibration measurements generated by the haptic vibrator at the current time frame corresponding to the plurality of potential values;
selecting a value among the plurality of potential values as an optimal amplitude of the pattern signal at the current time frame, the selected value corresponds to a minimum vibration measured among the plurality of vibration measurements; and
applying the optimal amplitude of the pattern signal at the current time frame and repeating above steps to iteratively obtain an optimal amplitude of the pattern signal at each subsequent one or more time frames, until the haptic vibrator has a vibration below a threshold.
