This paper presents a walkthrough evaluation method for assessing, in a Universal Access perspective, interactive systems. The methodology is an adaptation of the traditional cognitive walkthrough used for many years in the usability engineering community. Cognitive walkthrough involves a simulation of the problem-solving process of an average user, to(More)
This paper describes the framework and development process of adaptive user interfaces within the OASIS project. After presenting a rationale for user interface adaptation to address the needs and requirements of older users, the paper presents and discusses the architecture and functionality of the OASIS adaptation framework, focussing in particular on an(More)
Today, as the users and contexts of use of Information and Communication Technology (ICT) become more diverse, there is a significant need to understand all the factors that may affect the quality of the user-experience, and to measure them systematically.

This paper introduces the concept of Virtual Prints (ViPs) as an intuitive metaphor for supporting interaction and navigation, as well as a number of additional tasks in virtual environments (VEs). Three types of ViPs are described: Virtual Footprints, which are used for tracking user navigation (position, orientation and movement), Virtual Handprints,(More)
This paper presents an evaluation method, along with the underlying theory, for assessing interactive systems and specifying their quality in terms of universal access. The method is an adaptation of traditional walkthroughs and is aimed to incorporate user diversity, for example in terms of individual abilities, skills, background, levels of expertise,(More)
This paper introduces the harmonized accessibility methodology (HAM) that has been defined and deployed in the context of the ACCESSIBLE project. HAM is aimed to harmonize existing collections of related design knowledge, such as heuristics, guidelines, standards, etc., and thereby provide the grounds for defining ontology-based rules and, and thereby(More)
