Semantics-supported cooperative learning for enhanced awareness

Awareness is required for supporting all forms of cooperation. In Computer Supported Collaborative Learning (CSCL), awareness can be used for enhancing collaborative opportunities across physical distances and in computer-mediated environments. Shared Knowledge Awareness (SKA) intends to increase the perception about the shared knowledge, students have in a collaborative learning scenario and also concerns the understanding that this group has about it. However, it is very difficult to produce accurate awareness indicators based on informal message exchange among the participants. Therefore, we propose a semantic system for cooperation that makes use of formal methods for knowledge representation based on semantic web technologies. From these semantics-enhanced repository and messages, it could be easier to compute more accurate awareness

Designing internet of tangible things for children with hearing impairment

Tangible User Interfaces (TUIs) are a new, non-traditional way to interact with digital information using a physical environment. Therefore, TUIs connect a physical set of objects that can be explored and manipulated. TUI can be interconnected over the Internet, using Internet of Things (IoT) technology to monitor a child''s activities in real-time. Internet of Tangible Things (IoTT) is defined as a tangible interaction applied to IoT. This article describes four case studies that apply IoTT to children with cochlear implants and children whose communication is sign language. For each case study, a discussion is presented, discussing how IoTT can help the child development in skills such as: social, emotional, psychomotor, cognitive, and visual. It was found that IoTT works best when it includes the social component in children with hearing impairment, because it helps them to communicate with each other and build social-emotional skills

A model for a collaborative recommender system for multimedia learning material

Abstract. In a cluster of many servers containing heterogeneous multimedia learning material and serving users with different backgrounds (e.g. language, interests, previous knowledge, hardware and connectivity) it may be difficult for the learners to find a piece of material which fit their needs. This is the case of the COLDEX project. Recommender systems have been used to help people sift through all the available information to find that most valuable to them. We propose a recommender system, which suggest multimedia learning material based on the learner's background preferences as well as the available hardware and software that he/she has.

Finalmente, se recomienda emplear la metodología LPS para la totalidad de proyectos de construcción civil, puesto que permite mejorar la productividad, así como reducir costos y reducir los plazos de ejecuciónThe present research aims to evaluate productivity by applying the Last Planner System in the work Improvement of the San Juan - Ascope Educational Institution, La Libertad; It includes the elaboration of a master plan, the design of a planning Lookhead Planning and determine the percentage of the fulfillment plan for the chosen study activities in the work: Improvement of the educational institution San Juan - Ascope, La Libertad. In the present investigation, it was determined that the application of the LPS, if the application of the same is favorable since productivity was substantially improved, reducing by 0.47 months in the execution time and reducing by 14.17%, it was also possible to take advantage The maximum performance of each of the participants (pawn, officer, pawn, work teacher, resident and supervisor), without occurrence of accidents with a favorable impact of social actors (stakeholders) on the viability of the project. Finally, it is recommended to use the LPS methodology for all civil construction projects, since it allows improving productivity, as well as reducing costs and reducing execution deadlinesTesi

Collaborative explicit plasticity framework: a conceptual scheme for the generation of plastic and group-aware user interfaces

The advent of new advances in mobile computing has changed the manner we do our daily work, even enabling us to perform collaborative activities. However, current groupware approaches do not offer an integrating and efficient solution that jointly tackles the flexibility and heterogeneity inherent to mobility as well as the awareness aspects intrinsic to collaborative environments. Issues related to the diversity of contexts of use are collected under the term plasticity. A great amount of tools have emerged offering a solution to some of these issues, although always focused on individual scenarios. We are working on reusing and specializing some already existing plasticity tools to the groupware design. The aim is to offer the benefits from plasticity and awareness jointly, trying to reach a real collaboration and a deeper understanding of multi-environment groupware scenarios. In particular, this paper presents a conceptual framework aimed at being a reference for the generation of plastic User Interfaces for collaborative environments in a systematic and comprehensive way. Starting from a previous conceptual framework for individual environments, inspired on the model-based approach, we introduce specific components and considerations related to groupware

Usability Evaluation Trends in Ibero-American Countries

Usability evaluation is a major area of humancomputer interaction (HCI) in both academia and industry. According to Nielsen, on the Web, usability is a necessary condition for survival. If a website is difficult to use, people leave. If a homepage fails to clearly state what a company offers and what users can do on the site, people leave. If users get lost on a website, they leave. If a website’s information is hard to read or doesn’t answer users’ key questions, they leave. We conducted a survey in diverse Ibero-American countries of both academic institutions and software development companies to determine how usability evaluation is performed, taking into account methods, techniques, software tools, and usability laboratories

Modelo liviano de medidas para evaluar la mejora de procesos de desarrollo de software MLM-PDS

Companies in software development in Colombia face a number of problems such as the construction of software in a artesian, empirical and disorganized way. Therefore, it is necessary for these companies to implement projects to improve their development processes, because ensure the quality of products, by improving their software processes, is a step that should give to be able to compete in the market. To implement process improvement models, it is not enough to say whether a company is actually getting benefits, definitely one of the first actions in a to improvement project is to be able to determine the current status of the process. Only by measuring it is possible to know the state of a process in an objective ay, and only through this it is possible to plan strategies and solutions, about improvements to make, depending on the objectives of the organization. This paper proposes a light model to assess software development process, which seeks to help the Colombian software development companies to determine whether the process of implementing improvements, being effective in achieving the objectives and goals set to implement this, through the use of measures to evaluate the process of improving their development processes, allowing characterize the current practices of the company, identifying weaknesses, strengths and abilities of the processes that are carried out within this and thus control or prevent the causes of low quality, or deviations in costs or planning.MSC: 68Uxx, 68NxxLas empresas de desarrollo de software en Colombia enfrentan una serie de problemas tales como la construcción de software de forma artesanal, empírica y desorganizada. Por esto, es necesario que implementen proyectos para mejorar sus procesos de desarrollo, ya que asegurar la calidad de los productos,a través de la mejora de sus procesos de software, es un paso que deben dar para estar en condiciones de competir en el mercado nacional e internacional. Implementar modelos de mejora de procesos no es suficiente para decir siuna empresa realmente está obteniendo beneficios, definitivamente una de las primeras acciones en un proyecto de mejora es el poder determinar el estadoactual del proceso. Sólo midiendo es posible conocer el estado de un proceso de manera objetiva, y sólo gracias a esto se pueden planificar estrategias y soluciones acerca delas mejoras a realizar y según los objetivos de la organización. Este artículo propone un modelo liviano de medidas para evaluar un proyecto de mejora deprocesos de software, con el cual se busca ayudar a las empresas de desarrollode software colombianas a determinar si el proceso de mejora que implementan está siendo eficaz con relación a los objetivos y metas establecidas al inicio del proyecto. Esto se lleva a cabo a través del uso de medidas que permiten evaluar el proceso de mejora de sus procesos, facilitando la caracterizaciónde las prácticas actuales de la empresa y la identificación de las debilidades, fortalezas y habilidades de los procesos que son llevados a cabo dentro de ésta, permitiendo controlar y evitar las causas de baja calidad y desviaciones encostos o en planificación.MSC: 68Uxx, 68Nx
