Article: Process of design and usability evaluation of a telepsychology web and virtual reality system for the elderly: Butler
[show abstract] [hide abstract]
ABSTRACT: Butler is a multi-application system based on Internet technology and virtual reality, designed to meet the needs of elderly users. Its objectives are to assist elderly populations in accessing technology and new forms of communication, replicating, as far as possible the way of lineal interaction that this population group had traditionally to interact with information in order to facilitate the first contacts with technology. Butler is equipped with e-mail, videoconferencing, blogging, access to the Internet through a well-known web search engine, image and sound gallery, new contacts searcher, and two virtual reality environments. In this paper we describe Butler’s most relevant features taking into account the usability design process and the usability evaluation of the system, which, after pilot testing, have proven to be highly acceptable and satisfactory to users. We also present the results of evaluations pertaining to the iconography used in the program, the navigation and users’ help design process, and the first functional prototype, all of which were designed and redesigned with the aid of web heuristics and guidelines for the web design for elderly users. Results suggest important features to be taken into account when designing and developing this sort of application for the elderly.International Journal of Human-Computer Studies 10/2012; 71:350-362. · 1.17 Impact Factor -

ABSTRACT: The purpose of the present study was to analyse the psychometric properties of the 'Questionnaire of Sociocultural Influences on the Aesthetic Body Shape Model' (CIMEC-26) in a Spanish adolescent population. This questionnaire measures the influence of agents and situations that transmit the current aesthetic model, and assesses environmental influences favouring thinness. The CIMEC-26 was administered to a sample of 4031 female primary and secondary school students ranging in age from 10 to 17 years (M = 14, SD = 1.34). Results suggested that the CIMEC-26 has acceptable internal consistency (α = .93). The oldest group (15-17 years) had the highest scores on all factors and the highest total scores, suggesting greater influence of the aesthetic body shape model and higher vulnerability to social pressure to achieve it. Factor analysis suggested three moderately interrelated components of the scale. Confirmatory factor analysis showed that both the three-factor solution and the original five-factor structure had good fit indices, although the latter showed the best fit. The CIMEC-26 proved to be an effective instrument for research on the social influence on the aesthetic body model in female adolescents.European Eating Disorders Review 01/2012; 20(3):255-6. · 1.38 Impact Factor -
