Information objects are compared according to user a specified distance measure and the magnitude of this distance measure is reported to a user by producing audio tones representative of the magnitude of the distance measure between the information objects. In one embodiment, a user interface for computers, including audio feedback in which a substantially fixed pitch audio tone is associated with a first selected object, and a second audio tone, associated with a second selected object, varies in pitch as the second object is moved relative to the first object. User configurable audio tone parameters allow the use of any function relating variations in audio tone to a distance measure.
