Towards an engineering approach for advanced interaction techniques in 3D environments

National audienceIn recent years, Virtual Environments have appeared in new areas such as mass-market, web or mobile situations. In parallel, advanced forms ofinteractions are emerging such as tactile, mixed, tangible or spatial user interfaces, promoting ease of learning and use. To contribute to the democratization of 3D Virtual Environments(3DVE) and their use by persons who are not experts in 3D and occasional users, simultaneously considering Computer Graphics and Human Computer Interaction design considerations is required. In this position paper, we first provide an overview of a new analytical framework for the design of advanced interaction techniques for 3D Virtual Environment. It consists in identifying links that support the interaction and connect user’s tasks to be performed in a 3DVE with the targeted scene graph. We relate our work to existing modeling approaches and discuss about our expectations with regards to the engineering of advanced interaction techniqu

Brave New GES World:A Systematic Literature Review of Gestures and Referents in Gesture Elicitation Studies

How to determine highly effective and intuitive gesture sets for interactive systems tailored to end users’ preferences? A substantial body of knowledge is available on this topic, among which gesture elicitation studies stand out distinctively. In these studies, end users are invited to propose gestures for specific referents, which are the functions to control for an interactive system. The vast majority of gesture elicitation studies conclude with a consensus gesture set identified following a process of consensus or agreement analysis. However, the information about specific gesture sets determined for specific applications is scattered across a wide landscape of disconnected scientific publications, which poses challenges to researchers and practitioners to effectively harness this body of knowledge. To address this challenge, we conducted a systematic literature review and examined a corpus of N=267 studies encompassing a total of 187, 265 gestures elicited from 6, 659 participants for 4, 106 referents. To understand similarities in users’ gesture preferences within this extensive dataset, we analyzed a sample of 2, 304 gestures extracted from the studies identified in our literature review. Our approach consisted of (i) identifying the context of use represented by end users, devices, platforms, and gesture sensing technology, (ii) categorizing the referents, (iii) classifying the gestures elicited for those referents, and (iv) cataloging the gestures based on their representation and implementation modalities. Drawing from the findings of this review, we propose guidelines for conducting future end-user gesture elicitation studies

Usability Challenges with Insulin Pump Devices in Diabetes Care: What Trainers Observe with First-time Pump Users

Insulin pumps are designed for the self-management of diabetes mellitus in patients and are known for their complexity of use. Pump manufacturers engage trainers to help patients use the devices correctly to control the symptoms of their disease. Usability research related to insulin pumps and other infusion pumps has centered on the relationship between user interface design and the effectiveness of task completion by a single evaluator perspective, namely first-time users. From a different perspective, there is a lack of insight into the experiences of insulin pump trainers during learning sessions with first-time users. The focus of the study is to present the lived experiences and shared impressions of the insulin pump trainers. Their narratives will be used to conduct an interpretive examination of the phenomena uncovered and to provide the essence of their lived experiences

A review of the role of sensors in mobile context-aware recommendation systems

Recommendation systems are specialized in offering suggestions about specific items of different types (e.g., books, movies, restaurants, and hotels) that could be interesting for the user. They have attracted considerable research attention due to their benefits and also their commercial interest. Particularly, in recent years, the concept of context-aware recommendation system has appeared to emphasize the importance of considering the context of the situations in which the user is involved in order to provide more accurate recommendations. The detection of the context requires the use of sensors of different types, which measure different context variables. Despite the relevant role played by sensors in the development of context-aware recommendation systems, sensors and recommendation approaches are two fields usually studied independently. In this paper, we provide a survey on the use of sensors for recommendation systems. Our contribution can be seen from a double perspective. On the one hand, we overview existing techniques used to detect context factors that could be relevant for recommendation. On the other hand, we illustrate the interest of sensors by considering different recommendation use cases and scenarios

Facing Evolution on Industry 4.0: Modular Monitoring and Adaptive & Adaptable Visualization for Industrial Cyber-Physical Systems

Industry 4.0 comes to play an important role in various industrial domains where monitoring industrial cyberphysical systems (ICPSs) is becoming essential. This is due to the necessity to efficiently collect data from industrial processes for then making decisions that can impact on the operation of the industrial systems. Typically, the ICPSs are composed by heterogeneous, distributed and autonomous physical devices which can evolve over time. Thus, this makes necessary the adaptation of the monitoring system according to the physical devices. In this dissertation, it is proposed a monitoring system for ICPSs that evolve over time, that has been designed for multiple domains. In this proposal, the data capture and storage beside the ICPS evolution detection and information visualization are considered. To do so, the proposed solution is composed by two subsystems: (I) Modular Monitoring System which is based on the union of different standards able to capture data and store it in a structured manner and; (II) Personal Visualization & Evolution Detection System where the user has the possibility of customizing its visualization and the system is able to trigger alerts on ICPS evolution. In order to validate the proposal a prototype of each system has been developed and finally evaluated.La Industria 4.0 juega un papel importante en diversos ámbitos industriales donde la monitorización de los sistema ciber-físicos industriales (en inglés, Industrial Cyber-Physical Systems, abreviadamente ICPSs) se está convirtiendo en parte esencial. Esto se debe a la necesidad de recolectar datos de los procesos industriales de manera eficiente para luego tomar decisiones que puedan impactar en el funcionamiento de los sistemas industriales. Normalmente, los ICPSs están compuestos por dispositivos físicos heterogéneos, distribuidos y autónomos que pueden evolucionar con el tiempo. Por lo tanto, esto hace que sea necesaria la adaptación de los sistemas de monitorización de acuerdo con los dispositivos físicos. En esta tesis se propone un sistema de monitorización para ICPSs que evolucionan con el tiempo, el cuál ha sido diseñado para múltiples dominios. En esta propuesta se considera la captura y almacenamiento de datos además de la detección de la evolución y la visualización de la información. Para ello, la solución propuesta se compone de dos subsistemas: (I) Modular Monitoring System que se basa en la unión de diferentes estándares capaces de capturar datos y almacenarlos de forma estructurada y; (II) Personal Visualization & Evolution Detection System donde el usuario tiene la posibilidad de personalizar su visualización y el sistema es capaz de generar alertas en caso de que se produzca una evolución. Para validar la propuesta se ha desarrollado un prototipo de cada sistema y finalmente se ha evaluado.Industry 4.0 sona handia hartzen ari da egungo gizartean.

Método para la evaluación de usabilidad de sitios web transaccionales basado en el proceso de inspección heurística

La usabilidad es considerada uno de los factores más importantes en el desarrollo de productos de software. Este atributo de calidad está referido al grado en que, usuarios específicos de un determinado aplicativo, pueden fácilmente hacer uso del software para lograr su propósito. Dada la importancia de este aspecto en el éxito de las aplicaciones informáticas, múltiples métodos de evaluación han surgido como instrumentos de medición que permiten determinar si la propuesta de diseño de la interfaz de un sistema de software es entendible, fácil de usar, atractiva y agradable al usuario. El método de evaluación heurística es uno de los métodos más utilizados en el área de Interacción Humano-Computador (HCI) para este propósito debido al bajo costo de su ejecución en comparación otras técnicas existentes. Sin embargo, a pesar de su amplio uso extensivo durante los últimos años, no existe un procedimiento formal para llevar a cabo este proceso de evaluación. Jakob Nielsen, el autor de esta técnica de inspección, ofrece únicamente lineamientos generales que, según la investigación realizada, tienden a ser interpretados de diferentes maneras por los especialistas. Por tal motivo, se ha desarrollado el presente proyecto de investigación que tiene como objetivo establecer un proceso sistemático, estructurado, organizado y formal para llevar a cabo evaluaciones heurísticas a productos de software. En base a un análisis exhaustivo realizado a aquellos estudios que reportan en la literatura el uso del método de evaluación heurística como parte del proceso de desarrollo de software, se ha formulado un nuevo método de evaluación basado en cinco fases: (1) planificación, (2) entrenamiento, (3) evaluación, (4) discusión y (5) reporte. Cada una de las fases propuestas que componen el protocolo de inspección contiene un conjunto de actividades bien definidas a ser realizadas por el equipo de evaluación como parte del proceso de inspección. Asimismo, se han establecido ciertos roles que deberán desempeñar los integrantes del equipo de inspectores para asegurar la calidad de los resultados y un apropiado desarrollo de la evaluación heurística. La nueva propuesta ha sido validada en dos escenarios académicos distintos (en Colombia, en una universidad pública, y en Perú, en dos universidades tanto en una pública como en una privada) demostrando en todos casos que es posible identificar más problemas de usabilidad altamente severos y críticos cuando un proceso estructurado de inspección es adoptado por los evaluadores. Otro aspecto favorable que muestran los resultados es que los evaluadores tienden a cometer menos errores de asociación (entre heurística que es incumplida y problemas de usabilidad identificados) y que la propuesta es percibida como fácil de usar y útil. Al validarse la nueva propuesta desarrollada por el autor de este estudio se consolida un nuevo conocimiento que aporta al bagaje cultural de la ciencia.Tesi

A mapping study on documentation in Continuous Software Development

Context: With an increase in Agile, Lean, and DevOps software methodologies over the last years (collectively referred to as Continuous Software Development (CSD)), we have observed that documentation is often poor. Objective: This work aims at collecting studies on documentation challenges, documentation practices, and tools that can support documentation in CSD. Method: A systematic mapping study was conducted to identify and analyze research on documentation in CSD, covering publications between 2001 and 2019. Results: A total of 63 studies were selected. We found 40 studies related to documentation practices and challenges, and 23 studies related to tools used in CSD. The challenges include: informal documentation is hard to understand, documentation is considered as waste, productivity is measured by working software only, documentation is out-of-sync with the software and there is a short-term focus. The practices include: non-written and informal communication, the usage of development artifacts for documentation, and the use of architecture frameworks. We also made an inventory of numerous tools that can be used for documentation purposes in CSD. Overall, we recommend the usage of executable documentation, modern tools and technologies to retrieve information and transform it into documentation, and the practice of minimal documentation upfront combined with detailed design for knowledge transfer afterwards. Conclusion: It is of paramount importance to increase the quantity and quality of documentation in CSD. While this remains challenging, practitioners will benefit from applying the identified practices and tools in order to mitigate the stated challenges
