The Matching Person and Technology model, as shown in this diagram, with AT as the example, occurs within
and requires assessment of the context of environmental and personal factors.
To do that, the ATA process has to be evaluated by those dimensions, described
by Scherer and DiCowden (2008), of well-being that involve person, milieu, and
technology.
Accessibility at this level is determined by the possibility and the satisfaction
of the contacts, measured by the following dimensions: the costs perceived by the
users in terms of use and access to the service for obtaining the goal, the possibil-
ity to reach the service (availability), the ease of contact (comfort), the expectation
of the users (appearance), and the users' perceived (or known) performance of the
service. The efficiency in the ATA process is guaranteed by the collection of data
and by the center for technical aid's staff (multidisciplinary team). The efficiency,
defined as the “Resources expended in relation to the accuracy and completeness
with which users achieve goals” (ISO 1998), is measured by the costs in terms of
time and workload perceived by users to obtain the AT. In this step the efficiency
of the process, defined as “Accuracy and completeness with which users achieve
specified goals” (ISO 1998), is strictly related to the efficacy in ideal conditions. In
fact, before the users' UX evaluation of the AT and the use of the AT in a daily life
condition, it is impossible to measure the real effectiveness of the process and the
satisfaction of the user.
