Abstract. The adaptation of user interfaces for people with special needs is a promising approach in order to enable their access to digital services. Model-based user interfaces provide a useful approach for this purpose since they allow tailoring final user interfaces with a high degree of flexibility. This paper describes a system called Adaptation Integration System aimed at providing Cameleon Reference Framework model-based tools with a mechanism to integrate adaptation rules in the development process. Thus, more accessible user tailored interfaces can be automatically generated. The services provided by the system can be applied at both design time and runtime. At design time, a user interface can be tailored at any abstraction level in the development process. At runtime, changes in the context of use trigger the adaptation process. Adaptation rules are stored in a repository tagged with meta-information useful for the adaptation process, such as the granularity of the adaptations and the abstraction level. As case studies, two applications have been developed using the services provided by the system. One of them exploits the benefits at design time whereas the other application is devoted to describe the adaptation process at runtime. The results obtained in these two scenarios demonstrate the viability and potential of the Adaption Integration System since even inexperienced designers may efficiently produce accessible user interfaces.

"Assisted Interaction Data Analysis of Web-Based User Studies"

March 14 2015 ·

News

Abstract. User behaviour analysis requires defining experimental sessions with numerous participants. In this context, the specification of experiments is a demanding task, as several issues have to be considered such as the type of experiment, the type and number of tasks, the definition of questionnaires and the user interaction data to be gathered. The analysis of collected data is also complex and often requires repeatedly examining recorded interaction videos. In order to deal with these tasks, we present a platform called RemoTest which assists researchers to specify and conduct experimental sessions as well as to gather and analyse the interaction data. This platform has been applied to define different formal user studies on the web and has assisted researchers in detecting the main interaction characteristics of different user profiles and settings.

ABSTRACT

The Information Society demands that accessibility issues are taken into account in all user interfaces. To this end, the inclusion of accessibility requirements in the early phases of the conceptualization and development process can lead to the creation of barrier free user interfaces. As a consequence, users with special needs may be able to interact without having to undergo problematic situations. In this sense, the model-based automated interface generation promises to be a worthwhile basis for research which seeks to find practical systems for the creation of accessible user-tailored interfaces. The main advantage of this type of system is that they enable any designer to create suitable user interfaces whatever their level of expertise in accessibility issues. Hence such systems must include all the necessary accessibility requirements throughout their entire process.

This thesis defines a reference framework for the development of model-based automated user interface generation systems. The objective of this framework is to define and build a top-down methodology for improving the automated generation of user-tailored interfaces for people with special needs under different constraints and assessing the suitability of the user interfaces generated. In addition, this reference framework enables the definition of specific constraints which must be taken into account due to the explicit requirements of some developments.

The proposed reference framework has been assessed by the development of three different systems each one with specific requirements and each applicable under different scenarios in ubiquitous environments. The user-tailored interfaces obtained from these systems have been assessed using different expert-based techniques as well as by end-user testing.

In addition, support tools for facilitating the creation of the necessary models according to the Cameleon Reference Framework have been developed. Thus, the tedious task of dealing directly with the specification of accessibility requirements in different models such as the abstract user interface model and the task model has been simplified. Therefore, these tools along with the systems developed based on the defined reference framework help to contribute to the easy generation, management and maintenance of accessible user-tailored interfaces.

Experiment Design Workshop

Course

En un sentido literal, un experimento es una prueba pero desde el punto de vista másformal D. C. Montgomery lo define como “una prueba o serie de pruebas en las que sehacen cambios deliberados en las variables de entrada de un proceso o sistema paraobservar e identificar las razones de los cambios que pudieran observarse en larespuesta de salida”.Para analizar los resultados de los experimentos y obtener conclusiones válidas yobjetivas este taller pretende mostrar a los asistentes técnicas estadísticas que permitanentre otras cosas: comparar tratamientos experimentales, determinar las variablesverdaderamente influyentes, cuantificar el efecto de las variables en el resultado delexperimento, etc.El germen de este taller está basado en las ideas de G. E. Box, “Teaching engineersexperimental design with a paper helicopter”, y presentará un “toy problem” con el quelos asistentes podrán experimentar de manera real y aplicar las técnicas que sepresentarán.

Seminar

Las estrategias que emplean los usuarios para superar las dificultades con las que se encuentran en la Web son indicadoras de problemas de interacción y navegación. Por tanto, si somos capaces de detectar tales estrategias automáticamente podemos intervenir en la interfaz y solucionar problemas de usabilidad en tiempo real. Presentamos un método mediante el cual (1) identificamos las estrategias de superación en grupos de usuarios que son más proclives a sufrir problemas en la Web (usuarios con discapacidades); (2) desarrollamos y desplegamos estudios longitudinales para detectar automáticamente tales estrategias en poblaciones menos proclives a sufrir problemas; (3) ajustamos los algoritmos de detección en base al feedback recibido en los estudios. Markel Vigo investiga modelos cognitivos de comportamiento humano en la Web. Desde 2011 trabaja en el proyecto "COPE: Coping Strategies on the Web" en el que colaboran el "Web Ergonomics Lab" de la Universidad de Manchester (UK) y el Laboratorio de HCI de la UPV/EHU.

Seminar

Mari Feli González es Licenciada en Psicología por la Universidad Civil de Salamanca (2.004), ha realizado un Master en Neuropsicología Clínica por la Universidad Autónoma de Barcelona (2004-2007). En la actualidad, está realizando su trabajo de tesis doctoral: "Rendimiento cognitivo en el proceso de envejecimiento: Contribución de los factores biopsicosociales - ELES"  Trabaja en Matia Instituto Gerontológico - INGEMA como investigadora desde 2005. Dentro de esta área desarrolla, principalmente, proyectos de investigación relacionados con la caracterización, evaluación e intervención cognitiva y con el estudio, en las personas mayores, de los procesos cognitivos implicados en el manejo de las nuevas tecnologías. La charla se centrará en proyecto GUIDE - Gentle User Interfaces for Elderly People (GA: 248893). Esta charla es complementaria a la que en su día hicieron otros socios de este proyecto y se centrará en cómo se ha tenido en cuenta a los usuarios en este proyecto. A lo largo de los tres años de duración del proyecto GUIDE se ha seguido la aproximación User Center Design (UCD). Dependiendo de la fase del proyecto, se han adecuado los objetivos y la metodología de los estudios con los usuarios. Los resultados obtenidos en cada una de estas fases han sido tenidos en cuenta en el desarrollo del siguiente prototipo. A lo largo de estos tres años más de 150 participantes han evaluado el sistema. La mayoría de las evaluaciones se han realizado en España pero algunas de ellas también se han llevado a cabo en Alemania y en Reino Unido.
