Virtual Reality and Augmented Reality Laboratory

Virtual Reality and Augmented Reality Laboratory

 

The main activity of this laboratory is the development of tools, visualisation environments and applications based on Virtual Reality, Augmented and Mixed Reality, tracking and natural interaction, computer vision techniques and visual analytics of large amount of data for the resolution of problems and technological challenges. The most important areas of application are security and surveillance; automation and personal assistance in intelligent environments; surgery and legal and forensic medicine; architecture and urban planning and the visualisation and analysis of large volumes of data to support decision taking on a broad scale (e.g. Smart Cities).

 

The facilities and techniques offered are included in the CAM (Comunidad Autónoma de Madrid) Infrastructures Network of Laboratories with registry number 430.

The application sector of Virtual Reality, Augmented Reality and Visual Analysis techniques is very large, as they deal with quite transversal technologies.

 

VIRTUAL REALITY

The Virtual Reality (VR) concept makes reference to any digital environment created by a computer where it is possible to simulate physical situations of the real world, as well as imaginary worlds. The amount of presence inside a virtual environment is directly related to the degree of immersion of our senses. To achieve this goal, VR makes use of computer stereoscopic graphics in real time presented through different kind of displays (e.g. Head Mounted Displays or HMDs, large dimension stereoscopic screens or StereoWalls, multiple screens like a CAVETM system, etc.), tracking systems to monitor one or several users and sensorial haptic devices. In the Virtual Reality laboratory of CeDInt, our work is focused on the generation of realistic 3D content and applications that helps the user to feel immersed with the environment shown. We see Virtual Reality like a technological asset not only for visualisation and simulations of experiences but also as a great tool to provide solutions to everyday problems in real life. With this idea in mind, our projects have as one of its main objectives to detect and deal with those problems such as the development of a tool to reconstruct soft facial tissues or a system to monitor controlled environments to support decision taking. The most important areas of application are: Design, modelling and visualisation of objects and places of interest such as buildings, environments, industrial products, prototypes, etc.; Reconstruction and virtual visits to real historical places and cultural heritage; Visualisation of complex data and simulation of processes; Training and education of people in a collaborative way in order to tackle complex and/or dangerous situations; Scientific research in medicine through the simulation of real life conditions and the study of the behaviour of users in a practical and controlled environment.

 

AUGMENTED REALITY 

The main goal of Augmented Reality (AR) is the seamless integration of digital content with the image that users perceive from the real world. Literally speaking, it consists in the addition of information of interest over the surrounding environment. In contrast to Virtual Reality, AR does not simulate a real world experience. It uses the real physical space as a base to add contextual data in order to enrich the knowledge of the user about the environment. The most frequent example and one of the first commercial application of this technology was the insertion of the offside line in TV broadcasted football matches. In CeDInt, we work with Augmented Reality showing contents using personal mobile devices (e.g tablets or smartphones), in order to create experiences in which the user gets the information in a useful and original way. This technique provides a development framework for the study and research in a great list of areas such as entertainment, military training, engineering design, robotics, manufacturing and other industries. The most important areas of application of AR are: Location of users in unknown environments, using algorithms from the robotics sector, like SLAM and PTAM; Presentation of contextual information over the environment geometry; Provision of interactive contents, supporting the learning processes; Support to decision taking inside the industrial prototyping phase or visualisation of processes before the final stages of the project; Assistance to the accomplishment of complex assembling tasks, maintenance or surgery; Visualisation of construction projects in the early stages.

 

COMPUTER VISON

It is a branch of Artificial Intelligence that comprises the set of techniques that a machine uses to recognise the structure and properties of images as they are seen by humans. To achieve this goal, Computer Vision uses, among others, image processing techniques, pattern recognition, statistical learning and graph theories. In the Virtual Reality laboratory in CeDInt, we use computer vision to support the lines of Virtual Reality and Augmented Reality. Using this technology, we process the images captured by cameras and other video sources to provide the necessary data to the final applications, for example the detection of a certain object or the depth computation of objects in the scene in order to be able to interact with them. Among the most important techniques that we usually work in our projects we can find: Segmentation; Feature extraction, Stereo-matching; Facial recognition; Reconstruction of environments.

 

VISUAL ANALYSIS OF INFORMATION

The resolution of problems, in the academic and the business sector, is directly related to how the data is analysed and shown to the final users. In the era of data explosion that we live, this can have catastrophic consequences if researches do not have the tools and appropriate methodologies to make easier its understanding. These reasons have made the visualisation of information and visual analytics extraordinary active research areas in the recent years. The first has as its main objective the visual representation of abstract information in a comprehensive and useful way to the user; the second reinforces the human skill to reason and understand complex and dynamic scenarios though the perception mechanisms. The final goal of both is the acquisition and extraction of knowledge from raw data though interactive visual metaphors. Nowadays, the projects of CeDInt in this area tackle the following topics: Representation of Geospatial information; Temporal analysis (line of time) of data; Complex pattern understanding in urban areas; Data indicators representation using Virtual and/or Augmented Reality environments.

The main infrastructure of the Virtual Reality and Augmented Reality laboratory in CeDInt is a stereoscopic projection CAVETM system (Cave Automatic Virtual Environment). It is basically a 3D immersive visualisation system in which the illusion of immersion is achieved using a stereo rear projection technology called Active Infitec®+ though five screens of great dimensions, arranged perpendicularly to simulate a cube in which the user is completely surrounded. Besides, the laboratory has an advanced back projection system (3D PowerWall) with capacity for 30 people and a portable Virtual Reality system comprising an assembling screen and two DLP projectors

Location

The dependencies of the laboratories are located in the Centre of Energy Efficiency (Centro de Domótica Integral) in the Campus of Montegancedo.
