Abstract. Moving rapidly into digital economy expands the need for accessibil-
ity coming from the growing number of people with disabilities, in various con-
texts. Additionally, ubiquitous computing has amplified the need for interactive
systems to be able to adapt to their context of use, enhancing their utility while
preserving usability. Cloud4all project [0] aims to develop a complete new
paradigm in accessibility, by replacing adaptation of individual products and
services, with auto-configuration of any mainstream product or service, using
cloud technologies to activate and augment any natural accessibility the product
or service has, based upon a set of the user’s Needs & Preferences (N&Ps). In
order to assess this goal, Cloud4all has developed an evaluation framework, as
part of the User Centred Design (UCD) iterative process. This paper provides
an overview of the 1
st
pilots’ evaluation framework, together with ideas and
plans about the general framework of the pilot test.
Keywords: Accessibility, evaluation framework, auto-configuration, scenario,
usability, user experience, Cloud4all.
1 Introduction
In order to be useful, ubiquitous systems need to be designed following user centered
design, so that the users’ Needs & Preferences (N&Ps) are taken into account in the
entire design and development process [2]. The goal of this user centered design
(UCD) is to create tools and products that satisfy the user who is willing to use them
due to their increased utility, ease of use, and pleasure provided by the interaction
with them. However, the evaluation of pervasive computing systems and their influ-
ences on users is quite difficult because it requires analysis of real users in a real con-
text [3].
User centered design is enhanced by the involvement of real users in a real context,
doing multiple evaluations of the products under development during the development
