TL;DR

This paper compares inspection and usage testing methods for evaluating E-services accessibility, finding that usage tests more effectively identify usability issues for people with disabilities.

Contribution

It introduces a comparative analysis of inspection and usage testing techniques for E-service accessibility evaluation, highlighting the superior problem detection rate of usage tests.

Findings

Usage tests identify more accessibility issues for disabled users.

Inspection methods are less effective in detecting usability problems.

Usage testing shows higher problem detection rates.

Abstract

This article proposes to describe and compare the contributions of various techniques of evaluation of the accessibility of E-services carried out starting from (i) methods of inspection (on the basis of traditional ergonomic criteria and accessibility) and (ii) of tests of use. It show that these are the latter which show the best rate of identification of the problems of uses for the poeple with disabilities
