The effects of structural cues from multiple metaphors on computer users' information search performance

Since the 1980s metaphors have been used to design computer interfaces in order to facilitate user learning. As computer systems become more complex, the issue of using a large number of metaphors of narrow scope to design interfaces has arisen. Several researchers have proposed the use of multiple metaphors in the design of computer systems. This study set out to compare the effects of structural cues derived from single versus multiple metaphors used in designing hypertext systems. A total of 54 undergraduate students were asked to perform selected information search tasks. The results show that the provision of metaphorical cues helped subjects to find a greater number of accurate answers in a shorter period of time. The more complete mapping between the base and target domains in the design of the interface, along with cues from multiple metaphors, may have helped subjects to develop more sophisticated representations of the hypertext structure. r 2002 Elsevier Science Ltd.
