Slack, Jon and Conati, Cristina (1992): Effective Graphics: Accessing Spatial Relations. In: Monk, Andrew, Diaper, Dan and Harrison, Michael D. (eds.) Proceedings of the Seventh Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers VII August 15-18, 1992, University of York, UK. pp. 175-189.

“Graphical interfaces derive part of their effectiveness from encoding to-be-communicated information as spatial relations. Encoding the information in this way facilitates the User's access to it by exploiting the rapid perceptual operations that identify and encode the spatial relations implicit in the visual array. The paper outlines a representation framework for the cognitive/perceptual encoding of graphically presented information. The processes that access the information by extracting and decoding spatial relations can be specified within this framework. These specifications provide a basis for costing the information extraction routines thereby enabling the notion of `effective graphics' to be quantified. An example is worked through in detail, showing how these ideas can be applied to the generation of the optimal graphical format for quantitative relational data.”
