“…ESM is a research method that is used to assess phenomena at the time they occur, from the human perspective, in order to maximize the validity of the data [23]. Lutille et al in [23] claimed that the best time to ask the user about the preferences and/or the user needs is in the midst of the actual activity being closely inspected.…”

The usage of network-demanding applications is growing rapidly such as video streaming on mobile terminals. However, network and/or service providers might not guarantee the perceived quality for video streaming that demands high packet transmission rate. In order to satisfy the user expectations and to minimize user churn, it is important for network operators to infer the end-user perceived quality in video streaming. Today, the most reliable method to obtain end-user perceived quality is through subjective tests, and the preferred location is the user interface as it is the closest point of application to the enduser. The end-user perceived quality on video streaming is highly influenced by occasional freezes; technically the extraordinary time gaps between two consecutive pictures that are displayed to the user, i.e., high inter-picture time. In this paper, we present a QoE instrumentation for video streaming, VLQoE. We added functionality to the VLC player to record Multimed Tools Appl a set of metrics from the user interface, application-level, network-level, and from the available sensors of the device. To the best of our knowledge, VLQoE is the first tool of its kind that can be used in user experiments for video streaming. By using the tool, we present a two state model based on the inter-picture time, for the HTTP-and RTSP-based video streaming via 3.5G. Next, we studied the influence of inter-picture time on the user perceived quality through out a user study. We investigated the minimum user perceived inter-picture time, and the user response time.

La ingeniería de requisitos (IR) al identificar características esperadas del software a construir, plantea retos de comunicación tales como: eliminación de ambigüedad del lenguaje, entendimiento de la terminología técnica y facilidad de expresión.Este trabajo propone una propuesta metodológica para mejorar la comunicación entre los stakeholders durante el proceso de IR, enmarcado desde la ingeniería de procesos y las estrategias de comunicación, contextualizadas en las técnicas de elicitación de conocimiento (TEC) y las técnicas de comunicación (TC).Dada la naturaleza altamente humana de la IR, se mostrará cómo esta propuesta permite potencializar los procesos de comunicación. Para lograrlo, metodológicamente se llevó a cabo 4 etapas: (1) identificación de técnicas que aportan a la comunicación; (2) especificación formal de dichas técnicas para comprenderlas en su uso; (3) definición de propuesta metodológica para la IR; y (4) aplicación de la propuesta en una muestra aleatoria adquirida de empresas de desarrollo de software.

Abstract. Three tools for acquiring data about people, their behavior, and their use of technology in natural settings are described: (1) a context-aware experience sampling tool, (2) a ubiquitous sensing system that detects environmental changes, and (3) an image-based experience sampling system. We discuss how these tools provide researchers with a flexible toolkit for collecting data on activity in homes and workplaces, particularly when used in combination. We outline several ongoing studies to illustrate the versatility of these tools. Two of the tools are currently available to other researchers to use.
