ABSTRACT:
An apparatus for searching for a sensed object which is capable of immediately finding the direction in which a movable sensed object is present, from the contents displayed on an operation unit at hand. The searching apparatus includes a portable operation unit, an absolute direction sensor contained in the operation unit and generating an absolute direction signal which indicates an absolute direction, a removal sensor for automatically sensing a removal of the operation unit from the sensed object, a displacement sensor for sensing the state of displacement of the operation unit to generate displacement information, a controller generating direction indicating information which indicates the direction in which the sensed object is present, based on the displacement information and the absolute direction signal, a display for displaying contents of the direction indicating information; and a manual operation element for controlling the contents displayed on the display through the controller.
