Since mobile applications reach much deeper into everyday life, it is however important to better consider user behaviour for the service evaluation. In this paper we introduce the Behaviour Assessment Model (BAM), which is designed to gaining insights about how well services enable, enhance and replace human activities. More specifically, the basic columns of the evaluation framework concentrate on (1) service actuation in relation to the current user context, (2) the balance between service usage effort and benefit, and (3) the degree to which community knowledge can be exploited. The evaluation is guided by a process model that specifies individual steps of data capturing, aggregation, and final assessment. The BAM helps to gain stronger insights regarding characteristic usage hotspots, frequent usage patterns, and leveraging of networking effects showing more realistically the strengths and weaknesses of mobile services.

Este tipo de dispositivos han mejorado sus propiedades exponencialmente dotándose de capacidades de trabajo dignas de un ordenador personal y de pequeños sensores que enriquecen las aplicaciones. Por el contrario, el desarrollo del campo de usabilidad para este tipo de aplicaciones y dispositivos no ha avanzado a un nivel acorde. Aunque existen varios estándares y metodologías de evaluación, no existe una herramienta de evaluación remota específica para entornos de contextos dinámicos, muy característicos de este tipo de dispositivos. Por ello, se expone mediante este trabajo una plataforma de evaluación remota que registra las propiedades del contexto en uso mediante el mismo dispositivo. Asimismo se presenta una evaluación preliminar realizada con una aplicación móvil híbrida real donde se estudia el bajo nivel de influencia de la plataforma dentro de la interacción.

The ability of mobile devices to access information and services from anywhere and anytime is the main reason that empowers the massive usage of this kind of technology. Software quality has to be improved by developing mobile device interaction models according to the user necessities. These necessities have more kind of users than ever. It means the quality in use improvement is vital to the interaction.

As a result, many research fields have focused on the study and improvement of such devices. The current Smartphones are the best example of the research and the evolution of these technologies. Moreover, the software design and development is progressively more focused on the user; finding and developing new mobile interaction models. In order to do so, knowing what kind of problems the users could have is vital to enhance a bad interaction design. Unfortunately, a good software quality evaluation takes more time than the companies can invest. The contribution revealed in this work is a new approach to quality testing methodology focused on mobile interactions and their context in use where external capturing tools, such as cameras, are suppressed and the evaluation environments are the same as the user will use the application. By this approach, the interactions can be captured without changing the context and consequently, the data will be more accurate, enabling the evaluation of the quality-in-use in real environments.

One of the disadvantages of this fast evolution is that not all users have been used to this new technologies, basically because the way of doing a task has drastically changed. This problem is known as “increase of the technological or digital gap”. In order to reduce this technological gap we have designed, implemented and evaluated a new Virtual Learning Environment (VLE) based on digital pens. This solution consists of the integration of typical devices with a Learning Management System (LMS), concretely, Google Apps. A digital pen looks and feels like a normal ballpoint pen but thanks to it the handwriting can be captured, stored and sent by a safe way. In this case these data are sent to the LMS where students can manage and share notes by this platform and complete an existing document in the LMS with the digitalized information. The platform also offers a way to evaluate the students. Students can do several tests created by teachers previously. To carry out this activity, students will use a digital pen. Thus, the digitized information with the answers of the students will send to the platform where the tests are corrected immediately.

In order to achieve this, enterprises are growing awareness of the fact that evaluating the product's internal and external quality is not enough anymore. The user experience and the quality in-use of a product are equally important, if not more. This paper describes a framework for the measure and evaluation of the user experience based on the standard ISO/IEC 9126-4. The evaluation is based on four main aspects: effectiveness, productivity, safety and satisfaction. The aim of this paper is to prove that the evaluation of the quality in use of mobile services can be significantly sped up by the automation of its capture and analysis processes.
