RGB-D datasets using microsoft kinect or similar sensors: a survey

RGB-D data has turned out to be a very useful representation of an indoor scene for solving fundamental computer vision problems. It takes the advantages of the color image that provides appearance information of an object and also the depth image that is immune to the variations in color, illumination, rotation angle and scale. With the invention of the low-cost Microsoft Kinect sensor, which was initially used for gaming and later became a popular device for computer vision, high quality RGB-D data can be acquired easily. In recent years, more and more RGB-D image/video datasets dedicated to various applications have become available, which are of great importance to benchmark the state-of-the-art. In this paper, we systematically survey popular RGB-D datasets for different applications including object recognition, scene classification, hand gesture recognition, 3D-simultaneous localization and mapping, and pose estimation. We provide the insights into the characteristics of each important dataset, and compare the popularity and the difficulty of those datasets. Overall, the main goal of this survey is to give a comprehensive description about the available RGB-D datasets and thus to guide researchers in the selection of suitable datasets for evaluating their algorithms

Desarrollo de un videojuego con Kinect y Unity para la enseñanza de matemáticas

El desarrollo de aplicaciones orientadas a facilitar el aprendizaje y la enseñanza en la primaria es un campo que ha estado en desarrollo desde que la tecnología digital ha alcanzado las clases de las escuelas. Mientras que la enseñanza de las matemáticas en ambientes públicos ha prevalecido a través de la palabra escrita en libros estudiantiles, desde la aparición de los videojuegos didácticos se ha intentado complementar el uso de estos al aprendizaje tradicional. El objetivo principal de este Trabajo de Fin de Grado ha sido implementar un juego interactivo didáctico que sirviera para realizar operaciones matemáticas simples a través de la interacción directa y el movimiento de todo el cuerpo del alumno, permitiendo así un entorno dinámico y activo que fomente el aprendizaje y la actividad física del estudiante. Se han realizado pruebas con estudiantes de las edades objetivo para las que el juego puede resultar estimulante en su educación con el objetivo de ver los resultados de la combinación de actividad física y resolución de operaciones matemáticas. Ver la facilidad de estos mismos estudiantes de integrarse con el juego es lo que ha permitido enfocar correctamente el proyecto como base de futuras aplicaciones que fomentarán del mismo modo el aprendizaje de forma interactiva. Se puede concluir la efectividad de este modelo por medio de dichas pruebas.The development of applications aimed to the facilitation of learning in primary education groups is a field that has been in development since digital technology reached the school classes. While mathematic teachings has prevailed through the use of the written word in educational books, there has been a desire to complement didactic videogames and traditional learning since the appearance of the former. The main objective of this End of Degree Project has been to implement an interactive didactic game that would perform simple mathematical operations through the movement of the student's whole body, thus allowing a dynamic and active environment that encourages learning in an entertaining way and improves the student's physical activity. Tests have been conducted with students of the target age to see the effects of the game stimulations, and to see the results of a combination of physical activity with solving mathematical operations. Seeing their ease of integration with the game is what has allowed to correctly focus the project as a basis for future applications that will similarly promote learning in an interactive way. The effectiveness of this model can be concluded through these tests.Ingeniería Informática (Plan 2011
