Spatial Ability, Imagery and Human-Computer Search Dynamics.
Vigil, P. J.
Online searching is a complex problem solving task requiring the searcher to combine multiple sets into Boolean expressions. Since spatial ability has been correlated with problem solving tasks which involve abstract conceptual associations, this report argues that it is a significant factor in the information user's ability to both comprehend and learn human-computer interface (HCI) search dynamics. Applications of route spatial knowledge (i.e., the memory of a sequence of events or the knowledge to execute a given task) and survey spatial knowledge (i.e., the global perspective of the network of events that organizes an activity or task) are evaluated and compared, and the use of spatial imagery in storing and retrieving semantic information is described. Individual differences in spatial ability, which compound the complexity of the system design task, are explored. It is concluded that powerful interface software that addresses human cognitive factors needs to be developed. It is projected that, once this has been achieved, the ability to capture and code expert searcher algorithms and expert intermediary interview techniques, and to put all of this capability and knowledge into a dynamic interface, will probably not be far in the future.
