“…For example, Benyon et al [16] reported a study which compared four different interfaces and found that older users were initially substantially slower with all the interfaces. However, the large difference was radically reduced with practice, a result that they put down to slowness in forming mental models.…”

Cognitive abilities and disabilities are increasingly important in today's information-based workplace, particularly in relation to the accessibility of advanced information society technologies. As this paper discusses, new technologies can create problems for human decision making, stress levels, general cognition and e-accessibility. Yet it is not easy to identify possible new e-accessibility solutions to these problems. This is where theories of cognitive aspects of e-accessibility could be useful to generate solutions to these problems of HCI in general and of accessibility in particular. The purpose of this paper is to report a new generative theory (called Simplex 2), provide validating evidence for it from two meta-analyses and demonstrate a proof of concept through the application of Simplex to the solution of HCI problems. Two qualitative meta-analyses are reported for two different samples (N 1 = 90 and N 2 = 100) of relevant and contemporary conference papers. Whilst a few more concepts were identified, only nine cognitive concepts emerged from both analyses, validating the predictions of Simplex, which is also used for cognitive user modeling. Given the sample sizes and the successful replication, it is clear that these nine factors feature prominently in current research and practice in universal access and inclusive design. Further support for the value of this theory is found in a consideration of the requirements of older adult users and from studies of cognitive overload and augmentation. Uses of Simplex include the evaluation of existing systems, assessment of user requirements, system development in combination with models of task, context of use and technology platform and through the concepts of cognitive augmentation and overload to identify future opportunities for new, accessible, cognitive solutions. A proof of concept of Simplex is demonstrated by the treatment of HCI accessibility problems and as a generative theory for the development of new solutions.

“…3), since the contextual conditions may determine the outcome of the user experience with a system. Such diversity may be induced by the user's (1) tasks; (2) characteristics, such as physiological, psychological and socio-cultural [3]; (3) cognitive situation; (4) behavioural situation; (5) access equipment and other user agents; and (6) social and environmental conditions. In terms of user characteristics, key personal differences may involve variances in gender, physical and cognitive abilities, language, culture, experience, background, etc.…”

“…The term usability was first introduced, and its importance recognised, long time before the appearance of computer systems and digital technologies. 3 As automation and machines started to be integrated into everyday life, usability started to be investigated in more depth. The advent of computer systems and the Internet, as well as their rapid integration in everyday life activities, have led to the establishment of usability as a formal term in the literature that encompasses the quality of interaction between users and a system.…”

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, equipment used, etc., as key input to evaluation. The method aims at addressing as many as possible of the qualities of a system that might affect diverse users throughout their usage of the system and which, ultimately, have an impact on the system's wide acceptance. The proposed method, described here, extends the cognitive walkthrough method by introducing a simulation of the users' reasoned action process in order to assess whether users can, and will be, in favour of accessing, exploring, utilising and, ultimately, adopting a system. Additionally, the method allows considering in the assessment process various aspects of diversity among target users and use conditions, rather than assessing for the so-called average user, aiming at incorporating accessibility, usability and acceptance as intrinsic measurements. Finally, the paper presents ORIENT, a prototype inspection tool developed as a means to further facilitate experts in conducting such walkthroughs in practice, and which offers step-by-step guidance throughout the process until final reporting. Preliminary experiences with the application of the method in the domain of e-Services are also discussed.

“…In TADEUS a functional role actually corresponds to a specific view of a task. The set of individual properties corresponds to user characteristics, such as "lefthanded", and thus allows us to incorporate the framework developed by Benyon et al [2].…”

User diversity and design representation: Towards increased effectiveness in Design for All

This paper addresses user modelling for "Design for All" in a model-based approach to Human-Computer Interaction, paying particular attention to placing user models within organisational role-and taskrelated contexts. After reviewing a variety of user modelling approaches, and deriving requirements for user modelling related to Design for All, the paper proposes a role-driven individualised approach. Such an approach is based on a model-based representation schema and a unifying notation that keeps the user's models and the contextual information transparent and consistent. Individualisation is achieved by coupling symbolic model specifications with neural networking on synchronisation links between symbolic representation elements. As a result, user modelling for Design for All is achieved not by stereotypical user properties and functional roles, but by accommodating the actual users' behaviour.
