    Augmented reality: an ecoloigcal blend
    (Elsevier, 2017-05) Raja Galián, Vicente; Calvo, Paco; Filosofía
    In this article we present Ecological Augmented Reality (E-AR), an approach that questions the theoretical assumptions of main-stream Augmented Reality (AR). The development of AR systems to date presupposes an information-processing theory of perceptionthat hinders the potential of the field.Generally, in AR devices, virtual symbolic information is superimposed upon the environment in such a way that the real and thevirtual may be processed, informationally speaking, in tandem. Thus, we find information in reality itself, as well as virtual symbolicinformation. But by increasing the burden of symbolic crunching, AR devices run the risk of saturating the user of the technology. AR systems developed under the principles of an ecological psychology may contribute to new and better levels of performance andadaptation to the user’s perceptual abilities. Our proposal is to develop AR devices such that reality itself is augmentednon-symbolically by blending real and virtual layers/information. Although there are seldom AR devices in the market that are designedecologically, two fields of research may well bring inspiration to AR developers. These are the design and manipulation of real objects,and ecological research in the field of sensory substitution. We consider them both in turn with an eye to putting forward a frameworkthat eschews any type of information-processing regarding the nature of our psychological processes. Ultimately, our aim is to providesome guidelines for the exploration.

    Plataformas virtuales e innovación docente universitaria: Affordance de una Guía de Trabajo Autónomo en Antropología para trabajar competencias de intervención en contextos de diversidad
    (Universidad de Murcia, Servicio de Publicaciones, 2014) Olmos Alcaraz, Antonia; Martínez Chicón, Raquel
    En el presente texto mostramos una experiencia desarrollada en la asignatura de Antropología impartida en los estudios de grado de Trabajo Social, analizando para ello la pedagogía de las affordances de SWAD (Sistema Web de Apoyo a la Educación), el Sistema de Gestión de Aprendizaje (Learning Management System, LMS) de la Universidad de Granada. Focalizamos nuestra exposición en la descripción del diseño y del uso hecho a un instrumento en concreto –una Guía de Trabajo Autónomo (GTA)– y las funcionalidades dadas a la misma por el profesorado y el alumnado, de cara a trabajar competencias para la intervención en contextos de diversidad cultural. La puesta en práctica de esta herramienta nos ha permitido, como mostraremos, evaluar de distintas formas no solo los conocimientos sino también las habilidades, actitudes y competencias, desarrolladas por el alumnado a lo largo del curso en su proceso de enseñanza-aprendizaje. Concluimos nuestro trabajo con una reflexión acerca del cambio de paradigma epistemológico al que estamos asistiendo en la actualidad

    Using smart sensors to monitor physical activity and technical–tactical actions in junior tennis players
    (2020-02-07) Torres-Luque, Gema; Giménez Egido, José María; Ortega Toro, Enrique; Verdú Conesa, Isidro; Cejudo Palomo, Antonio; Actividad Física y Deporte
    The use of smart devices to obtain real‐time data has notably increased in the context of training. These technological tools provide data which monitor the external load and technical–tactical actions related to psychological and physical health in junior tennis players. The purpose of this paper is to monitor technical–tactical actions and physical activity during a current tennis competition in the Green stage using a Zepp Tennis Smart Sensor 2. The participants were 20 junior tennis players (under 10 years of age), with an average age of 9.46 years. The total number of strokes (n= 21,477) during 75 matches was analyzed. The study variables were the following aspects: (a) number of strokes, (b) ball impact in the sweet spot; (c) racket speed; (d) ball spin; (e) calories burned; and (f) match time. The current system of competition, based on knockout, does not meet the World Health Organizationʹs recommendations for daily physical activity time. Players mainly used flat forehands with a lack of variability in technical–tactical actions which did not meet the current learning opportunity criteria of comprehensive methodologies. The competition system in under‐11 tennis should be adapted to the players’ characteristics by improving the variability and quantity of practice.
