Several member of the research group take part within JolasmATIKA pilot project, with the aim of transmitting certain computing concepts to students in non-universitary centers. It will be made by using games and by means of students of different grades. For more information see the video (in Basque language):

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.

Evidence suggests that compliance to accessibility standards does not guarantee a satisfying user experience on the Web. Theactual accessibility of a website is worthless if users cannot perceive it. Unmet content and functionality related expectations havebeen identified as the main user problems not covered by guidelines. We expand on this by examining the role played by subjectiveand experiential dimensions, and particularly expectations, on users’ perceived web accessibility. We conducted a study with11 blind participants, who had to navigate on 4 restaurant websites, to uncover how these expectations shape their accessibilityperception. The thematic analysis on the transcribed interviews reveals that expectations are built up on previous experiences(either physical or via web) and preconceived ideas. We found that aspects, such as prejudices on branding issues or memoriesevoked by past experiences or emotional bonds, can a ect how user perceive and experience accessibility. Web content explicitlylabelled as accessible arises the curiosity and creates expectations about the accessibility of the website. We also observed thatnon-met expectations are often related to a sense of uncertainty and doubts, which can have an impact not only on participants’perceived web accessibility but on their user experience.

R. Miñón, F. Paternò, M. Arrue, J. Abascal. Integrating adaptation rules for people with special needs in model-based UI development process. Universal Access in the Information Society. 2015. DOI: 10.1007/s10209-015-0406-3

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.

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.
