Los entornos de realidad virtual (RV) ofrecen cada vez más contenidos de mayor calidad y utilizan diferentes técnicas informáticas para mejorar la experiencia de uso final. En este trabajo, aplicamos técnicas de calibración del dispositivo de RV, creamos diferentes fuentes de luz, midiendo la radiancia de éstas en un entorno real e introducimos tex...
El avance tecnológico que se ha producido en los últimos 10 años está permitiendo de forma progresiva que la información digital se pueda mostrar en 3D y visualizar mediante gafas de Realidad Virtual (RV). Al igual que la tecnología avanza y se adapta, las pruebas para detectar deficiencias visuales del color también se van adecuando a las nuevas t...
Virtual reality (VR) environments are increasingly offering higher quality content. They use different computing techniques
to improve the final user experience. In this work, we create different light sources and introduce hyperspectral textures for
the object reflectance to boost the VR environment’s quality. In addition, we perform a quantitativ...
In virtual reality technology, it is necessary to develop improvements and apply new techniques that allow rapid progress and innovative development. Nowadays, virtual reality devices have not yet demonstrated the great potential they could develop in the future. One main reason for this is the lack of precision to represent three-dimensional scena...
In recent years, there have been very important advances in graphic computing and technology related to the capture and representation of real objects in both 2 and 3 dimensions. One of these technologies is virtual reality, which can be incorporated into common tasks in research laboratories, especially in laboratories related to color vision and...
Due to the increase in the use of virtual reality systems, the requirement for quality in it has also increased. The most important factor may be the quality of the visual appearance of the scenes shown in it. One of the aspects that affects the visual appearance, among other things, is the color constancy or the ability of an object to be perceive...
Virtual reality has become a great multimedia tool in which it is possible to represent 3D content. It can be used for many applications such as video games, telemedicine, teleworking or airplane simulators. However, visual appearance is an aspect that needs to be further improved if virtual reality wants to take on a much more professional use. Sh...
Technology is constantly evolving and, consequently, all the technological advances
taking place are regularly integrated into the daily life of society. During recent years,
there has been a trend towards virtual resources such as teleworking, telemedicine
and e-commerce. In many countries, this virtualisation process has been accelerated
by the c...
Virtual reality has reached a great maturity in recent years. However, the quality of its visual appearance still leaves room for improvement. One of the most difficult features to represent in real-time 3D rendered virtual scenes is color fidelity, since there are many factors influencing the faithful reproduction of color. In this paper we introd...
Color deficiency tests are well known all over the world. However, there are not applications that attempt to simulate these tests with total color accuracy in virtual reality using spectral color computing. In this work a study has been made of the tools that exist in the market in VR environments to simulate the experience of users suffering from...
Virtual reality has experienced a strong advance in recent years, its use in industries such as video games, automotive and medicine is now a reality. Previous work has determined that color is one of the most important characteristics when it comes to creating a sense of realism in the user. Therefore, through the use of spectral techniques we hav...
We introduced a Color Management System (CMS) within the virtual reality software whose native color space is RGB. The starting point was the chromatic characterization of two commercial HUD display devices (Oculus Rift CV1 and HTC Vive) and the definition of the colorimetric profiles associated with these devices. Then, a third part color manageme...
El avance tecnológico sigue su progreso inexorable desde que en los años 50 del siglo XX se inventase el transistor y diera comienzo la era digital. Este progreso lo podemos apreciar en muchos aspectos de la vida cotidiana, como en nuestras capacidades de comunicación, nuestras capacidades de cómputo e incluso, en aspectos lúdicos como televisión,...
La realidad virtual (VR) intenta representar en tiempo real escenas de la realidad, que se reconstruyen en los dispositivos informáticos mediante diferentes plataformas. Pero ¿cómo gestionan estas plataformas, internamente el color? Y ¿hasta qué punto son un fiel reflejo de la realidad? Los sistemas de gestión del color establecen una serie de tran...
Trabajos previos han demostrado la gran mejoría de los sistemas de visualización basados en Head Mounted Display (HMD) y realidad virtual. En concreto, se realizó un estudio de valoración subjetiva de escenas de realidad virtual en las que era posible visualizar réplicas de obras de arte. En dicho estudio se analizaban varios aspectos relacionados...
La realidad virtual (VR) se está introduciendo, en mayor o menor medida, en casi todos los ámbitos de nuestra vida cotidiana. Cuando oímos VR, generalmente lo asociamos a los videojuegos, pero actualmente podemos encontrar VR en visitas a museos, en el sector del turismo, en el ámbito de la medicina (simuladores para la formación médica, tratamient...
Virtual reality devices are having a great development nowadays. These Head-Mounted-Displays (HMD) based systems allow visual immersive experiences in virtual environments.
Recently, the group of authors have made the chromatic characterization of two of the most worldwide used virtual reality devices [1]. Likewise, they have developed a colour man...
Previous works have shown the great improvement of visualization systems based on Head Mounted Displays (HMD) and Virtual Reality (VR). In these previous pieces of research the authors carried out a subjective evaluation study of virtual reality scenes in which it was possible to visualize artwork replicas [1]. In that study, several aspects relate...
Students are immerse in a digital world, in which master classes are not enough; they need to interact with new technological trends. In addition, each student is different and they have his or her own difficulties, consequently sometimes the suggested methods or activities for the study are too general and do not meet the particular needs of each...
The measurement of the quality of light in both indoor and outdoor environments is a relevant topic that has gained attention due to its multiple applications. Recently, two colour rendering measurement recommendations have been approved, one sponsored by the Illuminating Engineering Society IES T-30 and the other by the International Commission on...
In this work, we studied the chromatic characterization of Head Mounted Displays (HMD) applied to Virtual Reality (VR) with the purpose of obtaining a better colour fidelity reproduction. We used two of the latest commercial version of HMD through Unity, a game development platform. It has been verified that no type of colour management is performe...
Head Mounted Displays (HMD) allows immersive experiences in virtual worlds and it would be expected to have many applications, in both fields: recreational and professional. The aim of this paper is to check the accuracy of the visual appearance of real objects captured through a 3D scanner, rendered in a PC and displayed in the latest development...
