AbstractThree separate methods are used to provide the user with sounds that help the user understand where a particular current position is relative to a "location of interest" (LOI) within the viewable object. First, the user is able to use sound marks to mark specific LOIs within viewable objects so that the user may return to those LOIs at a later time. Second, the user is provided with view regions which aurally indicate the LOS of frequeuntly used portions of the viewable object. Lastly, the user is given an aural indication of the current position of the position identifier relative to the viewable object as a whole. This is called relational positioning. Each type of aural LOI indication can be presented to the user regardless of how the user is moving through the viewable object.
