Techniques and equipment provided to persons with functional deficits to assist them in moving safely from one location to another. For people with blindness or low vision, the term orientation and mobility (OM) training is used. Orientation involves knowing where in space one is located. Mobility involves enacting a plan to get to a desired location. For blindness and vision deficits, OM training involves developing sensory awareness and using devices such as long canes, guide dogs, or electronic sensing aids.
