Multiple-Planes Pseudoscopic-to-Orthoscopic Conversion for 3D Integral Imaging Display
2015
In this paper, we propose an advanced pseudoscopic-to-orthoscopic conversion method for 3D integral imaging display systems. Compared to previous works, this method can generate more accurate images for orthoscopic 3D display using multiple reference planes and estimated depth information. 3D display results show the superiority of the proposed pseudoscopic-to-orthoscopic conversion method.
An overview of head tracking integral imaging three-dimensional display using smart pseudoscopic-to-orthoscopic conversion
2017
We overview a previously reported head tracking integral imaging three-dimensional (3D) display to extend viewing angle accommodated to a viewer's position without the crosstalk phenomenon. A head detection system is applied to obtain the head position and rotation of a viewer, and a new set of elemental images is then computed using the smart pseudoscopic-to-orthoscopic conversion (SPOC) method for head tracking 3D display. Experimental results validate the proposed method for high quality 3D display with large viewing angle.
Orthoscopic long-focal-depth 3D integral imaging
2006
Integral imaging systems are imaging devices that provide 3D images of 3D objects. When integral imaging systems work in their standard configuration the provided reconstructed images are pseudoscopic; that is, are reversed in depth. In this paper we present, a technique for formation of real, undistorted, orthoscopic integral images by direct pickup. The technique is based on the use of a proper relay system and a global mapping of pixels of the elemental-images set. Simulated imaging experiments are presented to support our proposal.
Full-parallax 3D display from the hole-filtered depth information
2015
In this paper we introduce an efficient hole-filling algorithm for synthetic generation of microimages that are displayed on an integral imaging monitor. We apply the joint bilateral filter and the median filter to the captured depth map. We introduce in any step of the iterative algorithm with the data from a new Kinect capture. As a result, this algorithm can improve the quality of the depth maps and remove unmeasured depth holes effectively. This refined depth information enables to create a tidy integral image, which can be projected into an integral imaging monitor. In this way the monitor can display 3D images with continuous views, full parallax and abundant 3D reconstructed scene fo…
Depth rendering of large incoherent scenes from integral images
2016
Integral imaging is a technique that provides the spatial and angular information of three-dimensional (3D) scenes through a single shot. Taking advantage of this capability, different applications have been developed. Some of these applications are the 3D display and digital post-processing, in particular depth-reconstruction from integral images.
Aproximación holística versus aproximación comunicativa en la evaluación de la producción oral en inglés
2014
El propósito de este artículo es mostrar el rendimiento comunicativo en las simulaciones en inglés en dos grupos contrastivos: estudiantes adiestrados en enseñanza integrativa en contraste con los que están siguiendo un curso de enfoque comunicativo. La evaluación de la producción oral mediante una aproximación por tareas a las actividades de simulación muestra que, aunque los estudiantes siguiendo el método comunicativo dominan mejor tales técnicas, los estudiantes del método integrativo son más aventajados en el dominio de la gramática. Sin embargo, la nota media de los alumnos del método integral no se encuentra demasiado alejada de la de los que han seguido el método comunicativo. La ra…
Touchless gestural interfaces for networked public displays
2015
In the near future, we can easily imagine a significant increment in diffusion of networked public displays, as well as novel interaction modalities used in their applications. In the following, we present two of the main challenges related to networked displays we are dealing with, with a particular focus on touchless gestural interfaces: overcoming interaction blindness (i.e. enable users to immediately guess the interactivity of the display, and the gestural nature of it) and performing evaluations in-the-wild (i.e. outside any controlled environment).
Acoustic rendering of particle-based simulation of liquids in motion
2009
In interaction and interface design, the representation of continuous processes often uses liquid metaphors, such as dripping or streaming. When an auditory display of such processes is required, an approach to sound-synthesis based on the physics of liquids in motion would be the most convincing, especially when real-time interaction is into play. In order to bridge the complexity of fluid-dynamic simulations with the needs of interactive sonification, we propose a multi-rate sound synthesis of liquid phenomena. Low-rate smoothed-particle hydrodynamics is used to model liquids in motion and to trigger sound-emitting events. Such events, such as solid-liquid collision, or bubble formation, …
Prevalence and Risk Factors for Internet Gaming Disorder (IGD) in a sample of 5,979 Italian Online Gamers
2020
Background: The prevalence of Internet Gaming Disorder (IGD) in the Italian population of gamers is unknown. Several risk factors, including time spent playing (TSP), are proposed as an epiphenomenon of emotional dysregulation. Methods: The study estimated the prevalence of IGD in at-risk Italian online gamers, and the interplay between alexithymia and other risk factors. 5,979 responders were surveyed. IGDS-SF9 estimated pathological gaming. TAS-20 measured Difficult in Identifying (DIF) and Describing Feelings (DDF), and Externally Oriented Thinking (EOT). Results: 43% of participants had pathological IGD scores. Male gender (OR=1.2, 95% C.I.=1, 1.5, p=0.019), TSP (OR=7.6, 95% C.I.=5.5, 1…
Physical play - How do we inspire and motivate young children to be physically active through play? An international analysis of twelve countries’ na…
2023
Lifelong movement and physical activity (PA) patterns develop during early childhood. Therefore, educators (teachers and practitioners) in early childhood education and care (ECEC) should provide opportunities to support children’s play, PA, and movement development. The World Health Organization (2019) offers new recommendations for PA, for children under five years. The guidelines do not specify the ways ECEC staff can support PA through play. Therefore, this paper investigates, how physical play (PP) is enacted globally. An international policy and practice analysis of twelve countries, (Australia [Victoria], Belgium [Flanders], Canada [Alberta], China, Finland, Ireland, Italy, Portugal,…
