ABSTRACT
This paper reports on the outcomes of the first phase of the eCAALYX project -- an European project which aim is to develop a complete solution that improves the quality of life of the older adult with chronic conditions by monitoring his health and by improving the communication with his caretakers. Specifically, the authors are responsible for creating a TV user interface for older adults with chronic conditions.
The work described followed a multi-disciplinary approach strongly influenced by Human-Computer Interaction (HCI) methodologies. The main contributions of this paper are two-fold and materialize into i) a user research study that covers aspects such as perception, cognition, mental and psychosocial changes that occur with age and ii) an example-based description of the process of creating personas. John, the diabetic persona, is the example provided that abstracts the process followed to generate the remaining personas in the project.

Nunes et al. describe the development of a number of user personas-standard user interface design tools in which subpopulations of the user community are characterized by fictional archetypes-to guide the development of user interfaces for older adults. Much of the paper lists the relevant infirmities of age-mainly, decreasing competence in the areas of vision, hearing, motor skills, cognition, and memory. None of this information is new, and its relevance to the design of interfaces for older populations has long been recognized. The persona development process reported in the paper is also a standard practice that is frequently described in introductory texts on human factors. The paper fails to discuss the presented personas' efficacy, and there is no mention of field testing and validation. This paper does not report any new research ideas, and the professional practices it describes are basic and well understood. Consequently, this paper is not recommended for the human factors and user interface design communities. Online Computing Reviews Service
