1. An apparatus comprising:
an ultrasonic actuator configured to provide haptic stimulation to a part of a body located at a target location by:
generating an ultrasonic signal; and
forming sound pressure at the target location via the generated ultrasonic signal;
an object sensor provided around the ultrasonic actuator and configured to detect an object within a region between the ultrasonic actuator and the target location; and
a control module configured to stop operation of the ultrasonic actuator based on detecting the object within the region.
