A computer-implemented method and apparatus for modifying an entity sensory representation. An entity sensory representation representing an entity is received. The entity sensory representation comprises a plurality of sensory representations that represent a plurality of items that are part of the entity. Each of the plurality of items is associated with a set of values for a set of measurable factors of interest. A set of scale factors is calculated for each of the plurality of sensory representations based on the set of values associated with the each of the plurality of items. The plurality of sensory representations is modified using the set of scale factors to form a plurality of modified sensory representations that establish a relative relationship between the plurality of items represented by the plurality of modified sensory representations with respect to the set of measurable factors of interest.
