Usability Problem Identification Using Both Low- and High-Fidelity Prototypes
Document Actions
This article describes an experimental comparison of using low and high fidelity prototypes in usability evaluations. In the experiment, substantially the same sets of usability problems were found in the low- and high-fidelity conditions. Moreover, there was a significant correlation between the proportion of subjects detecting particular problems in the low- and high-fidelity groups. In other words, individual problems were detected by a similar proportion of subjects in both the low- and high-fidelity conditions. The authors concluded that the use of low-fidelity prototypes can be effective throughout the product development cycle, not just during the initial stages of design. (Feb-01-98)
