The Electronic Memory Palace: Spatial Data Management Systems (SDMS) are those which rely on spatial clues as an indication of where specific information is located. Knowledge communities are assembled by the user in ways that ultimately assist in the retrieval of information. This concept can be implemented though the use of iconographic keys, or by association with the physical placement of the clues on the screen. The concept is applicable beyond the physical confines of the computer screen, and will be operable in 3-D spatial constructs configured into the fabric of rooms and buildings. The Electronic Memory Palace (EMP) will be the ultimate personal computer that can discern and assimilate the user's idiosyncrasies (vagaries, inconsistencies, ambiguities) by monitoring the interaction between the user and the SDMS construct. Based on that assimilation, the computer will assemble a predictive model of the user's associative thought patterns and verbal expressions. Interactivity between the computer and the user in this construct will become increasingly familiar as the computer assimilates the context sensitive criteria that characterize user preferences. The EMP will invoke the necessary contextual inferences to interact with the user on the highest personal level. As a result, the user will be able to engage in intimate conversation (dialogue) with the (personal) computer to bring forth ideas and concepts that neither user nor machine working alone could have produced.
