A haptic actuator may include a housing having opposing first and second ends and first and second coils carried by the housing adjacent respective first and second ends thereof. Each coil may have a respective passageway therethrough. The actuator may include a field member including first and second masses adjacent respective first and second ends of the housing, and a permanent magnet having first and second ends coupled to respective ones of the first and second masses. The actuator may also include first and second flexures mounting respective first and second masses to the respective first and second ends of the housing so that the field member is reciprocally movable within the passageways of the coils responsive to powering the coils and so that the ends of the permanent magnet are within respective passageways of the coils when the coils are unpowered.

The disclosure relates to technology for haptic stimulation. A haptic interface device comprises an array comprising haptic stimulation elements configured to generate a stimulation pattern. The haptic interface device comprises a controller configured to continually propagate the stimulation pattern on a user's skin, including repeatedly eliminate a portion of a first end of the stimulation pattern and replace the eliminated portion with a new portion at a second end of the stimulation pattern.

In one aspect, a headset may include a housing, at least one processor in the housing, a transparent display accessible to the processor and coupled to the housing, and at least first and second vibrators accessible to the processor and coupled to the housing. The first and second vibrators may be located at different positions with respect to the housing. The headset may also include storage accessible to the processor and coupled to the housing. The storage may include instructions executable by the processor to track a person as the person moves through an environment. The instructions may also be executable to, based on tracking the person, actuate one of the first and second vibrators to indicate a direction in which the person is to travel and/or to alert the person of an object that is within a threshold distance to the person.

A method for determining and mitigating over-excursion of an internal mass of an electromechanical transducer may include measuring a sensed signal associated with the electromechanical transducer in response to a driving signal driven to the electromechanical transducer, determining a non-linearity value based on the sensed signal, mapping the non-linearity value to a probability of over-excursion of the internal mass, and applying a gain to a signal path configured to generate the driving signal based on the probability.
