Overlapping Chat's Accessibility Requirements between students with and without disabilities due to the mobile limitations

Proceeding in: The 10th International Conference on Mobile Learning 2014.Took place 2014, 28 February, 2, March, in Madrid, Spain. The event Web site at http://mlearning-conf.org/oldconferences/2014/The use of Chats has been extended for mobile-learning (m-learning) environments in the last decade. Students and teachers can communicate in real time and they do not need to wait till their next tutoring date. However, Chats have many accessibility barriers and many students cannot use this collaborative tool. These accessibility barriers affect students with disabilities but students without disabilities can face the same accessibility problems too due to the restrictions and limitations of handheld devices. Previous studies have improved the accessibility of Chats for a specific environment or disabilities but none of them is focused on the limitations that students without disabilities can face when they are using Chats in handheld devices. This is the main aim of this research; specify how the Chats' accessible requirements have been elicited and analyze the benefits that obtained requirements can produce for people without disabilities in m-learning contexts.This research work has been partially supported by the MA2VICMR (S2009/TIC-1542) research projectPublicad

Toward a closer integration of usability into software development: a study of usability inputs in a model-driven engineering process

Even though the benefits of usability have widely been proven, it seems that development-oriented companies face many difficulties to introduce usability practices into their defined development processes. This paper describes the overall methodology deployed as an attempt to achieve a closer integration of usability practices in the software development process. Model-Driven Engineering (MDE) is used as a basis for this integration. Providing a precise framework composed of models and transformations, it allows to track usability problems and to highlight where exactly they occur in the development process. We will thus be able to link every step of the process to specific ergonomic inputs and to study their consequences on the usability of the generated system. Because MDE will only be used as a way among others to investigate some hypotheses on usability and User-Centered Design (UCD) in general, our results are expected to provide valuable and generic information on usability and UCD processes

Process Mining Concepts for Discovering User Behavioral Patterns in Instrumented Software

Process Mining is a technique for discovering “in-use” processes from traces emitted to event logs. Researchers have recently explored applying this technique to documenting processes discovered in software applications. However, the requirements for emitting events to support Process Mining against software applications have not been well documented. Furthermore, the linking of end-user intentional behavior to software quality as demonstrated in the discovered processes has not been well articulated. After evaluating the literature, this thesis suggested focusing on user goals and actual, in-use processes as an input to an Agile software development life cycle in order to improve software quality. It also provided suggestions for instrumenting software applications to support Process Mining techniques
