2. The second level is the UX evaluation of the assistive solutions (i.e., the matching
of users with technical solutions). This step is the core of the matching process,
when the user is involved in the trial of the AT and in the evaluation of the UX.
After the match, it is possible to measure the effectiveness in the real world of the
AT and the satisfaction of the user both with the AT and the ATA process by a
survey and questionnaires (Figure 15.6).
The UX evaluation is one of the most important steps for achieving the rehabilita-
tion priority indicated by the World Health Organization that is “to ensure access to
appropriate, timely, affordable, and high-quality rehabilitation interventions” (WHO
2011, p. 121) to provide ATs that are “suited to the environment” and “suitable for the
user” by also granting an “adequate follow-up to ensure safe and efficient use” (WHO
& the World Bank 2011, p. 118). In fact, the UX evaluation is applied for measuring both
the interaction with the AT and the assessment of the whole ATA process as perceived
by the users to evaluate and improve them.
Another kind of application of the UX framework is the design of the product. In the
next sections we will describe the sonification concept to create a particular kind of
UX evaluation of ATA
Measures of UX evaluation

Costs: Cost perceived by user
• Availability: Opportunity of access (by user self )

) The dimensions and the measures of the UX evaluation of the model's functioning of the ATA
process of a center for technical aid. In this schema, the UX evaluation of the AT, with its dimensions, is part
of the efficiency and efficacy evaluation of the relationship between the user and the center for technical aid.
