“…Existen varios proyectos relacionados que han realizado experiencias en TDI y usabilidad, de los cuales destacamos [10]; [11];[12]; [13]; [14]; [15]; [16]; [4] que se han centrado en servicios de T-Learning. En la mayoría de ellos se definen las características que deben tener dichos servicios y se recomienda, en gran medida, que estos deben ser fáciles de usar.…”

RESUMENEn este artículo propone la extensión de un método de inspección denominado RECOEXTDI (REcorrido COgnitivo EXtendido para aplicaciones de Televisión Digital Interactiva), que evalúa la usabilidad de aplicaciones soportadas en ambientes de Televisión Digital Interactiva (TDI). El método propuesto tiene tres insumos básicos: el método original del recorrido cognitivo, las características de las aplicaciones de TDI y una experimentación inicial realizada en un laboratorio de TDI. Para la evaluación de RECOEXTDI se describe un caso de estudio en el que se hace una evaluación de usabilidad de una aplicación TDI utilizando el método tradicional y el extendido. De esta manera, se comparan los resultados obtenidos con la ejecución de los dos métodos. El método RECOEXTDI permitió encontrar una mayor cantidad de problemas de usabilidad en menor tiempo comparado con el método tradicional. PALABRAS CLAVE: Evaluación de usabilidad, Métodos de Inspección, RECOEXTDI, Televisión Digital Interactiva (TDI) ABSTRACTThis article propose the extent of an inspection method called RECOEXTDI (REcorrido COgnitivo EXtendido para aplicaciones de Televisión Digital Interactiva) to evaluate the usability of applications supported on Interactive Digital Television (IDT) environments. The former method has three basic inputs: The original cognitive walkthrough method, the characteristics of TDI applications, and early testing performed in a TDI laboratory. To assess RECOEXTDI, it is described a case study in which an evaluation of the usability of a TDI application is made, by using the traditional and the extended method. In this way, the results obtained are compared with the implementation of the two methods described. The RECOEXTDI method allowed finding a larger number of usability problems in shorter time, compared with the traditional method.

Age Factors in Biometric Processing

In this chapter, we examine the implications of ageing for the usability of biometric solutions. We first set out what usability means, and which factors need to be considered when designing a solution that is 'usable'. We review usability successes and issues with past biometric techniques, in the context of a set of solutions, before considering how usability will be affected for ageing users because of the physical and cognitive changes they undergo. Finally, we identify the opportunities and challenges that ageing presents for researchers, developers and operators of biometric systems.

“…Using a WebTV system, trained older adults showed increased perception of social support and connectivity and strong intention to use the online system continuously (Cody, Dunn, Hoppin, & Wendt, 1999), though we should be cautious about the possible confounding effect of the relationship with a trainer on the positive effect of social computing. In addition, usability studies on older adult users of the interactive TV system also presented useful data on how to enhance interface design (Obrist, Bernhaupt, Beck, & Tscheligi, 2007).…”

The expansion of the social computing environment as a new basis for socioeconomic activities could enhance the quality of life of older adults, but also it could make the problem of digital divide more serious. In this study, the research directions and agenda of social computing for an aging society are presented, which have two major directions: basic study and applied study. Regarding human aspects in social computing mainly dealt with in the basic study, existing research and related theories on cognitive characteristics, information usage patterns, and social network site use of older adults were examined. In the applied study, a study about the most effective contents application and interfaces through user needs analysis, usage context analysis, prototype design, and so on, was conducted. Those studies are discussed to develop applications on a PC platform, mobile platform, and IPTV platform targeting the older adults population.
