Value Added by the Axiomatic Usability Method for Evaluating Consumer Electronics
In this paper we demonstrate how to use the axiomatic evaluation method to evaluate usability of consumer electronic products. The axiomatic evaluation method examines three domains of a product: customer, functional, and control domains. This method collects not only usability problems reported by the users, but also usability problems found through the mapping matrix between the three domains. To determine how well this new usability evaluation method works, an experiment was conducted to compare the axiomatic evaluation method with a think-aloud method. 60 participants were randomly assigned to use one method or the other to evaluate three popular consumer electronic devices. Number of usability problems discovered and completion time were collected and analyzed. Results showed that the axiomatic evaluation method performed better than the think-aloud method at finding usability problems for the mobile phone and about user expectation and control.
