AUK is a 3x3 multi-tier onscreen keyboard. It supports various entry modes, including 1 to 10-key and joystick modes, allowing text entry with a remarkable range of devices. This paper presents the menu structure of AUK, the alternative entry modes, and several layouts for novice, moderate and expert users. The potential of AUK, as a text entry solution(More)
In automatic user interface adaptation, developers pursue the delivery of best-fit user interfaces according to the runtime-supplied profiles of individual end users and usage contexts. Software engineering of automatic interface adaptability entails: (a) storage and processing of user and usage-context profiles; (b) design and implementation of alternative(More)
The potential of Information and Communication Technologies to improve the overall quality of life of all citizens cannot be underestimated. In particular, in the context of Ambient Intelligent environments, technological developments provide a great opportunity for the integration and the improvement of quality of life of people from vulnerable groups(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)
In the design of user interfaces that adapt automatically to end-users and usage contexts , designers should be prepared to cope with large design spaces; these spaces will be necessary to accommodate design constraints posed by the diversity in the target user population and the various contexts of use. Adaptation-oriented design is considered a powerful(More)
This paper presents an augmented reality environment for students' improved learning, which is based on unobtrusive monitoring of the natural reading and writing process. This environment, named SESIL, is able to perform recognition of book pages and of specific elements of interest within a page, as well as to perceive interaction with actual books and(More)
The Web is constantly evolving into an unprecedented and continuously growing source of knowledge, information and services, potentially ac-cessed at by anyone anytime, and anywhere. Yet, the current uptake rates of the Web have not really reached their full potential, mainly due to the design of modern Web-based interfaces, which fail to satisfy the(More)
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)
