ABSTRACT
As we discussed in Chapter 1, the accessibility of artifacts is a well-debated issue in human-computer interaction (HCI). In particular, researchers and practitioners have remarked strongly on the ethical aspects of the “right of access” for all users (Roulstone, 2010), concurrently supporting the diffusion of the international rules and guidelines for assessing and verifying the accessibility of technological products (e.g., Section 508, WCAG). Nevertheless, while accessibility is a well-discussed topic, the role of disabled users and the advantages of their involvement in the interaction evaluation are often undervalued as a secondary issue.
