Augmented and virtual reality evolution and future tendency
Augmented reality and virtual reality technologies are increasing in popularity. Augmented reality has thrived to date mainly on mobile applications, with games like Pokémon Go or the new Google Maps utility as some of its ambassadors. On the other hand, virtual reality has been popularized mainly thanks to the videogame industry and cheaper devices. However, what was initially a failure in the industrial field is resurfacing in recent years thanks to the technological improvements in devices and processing hardware. In this work, an in-depth study of the different fields in which augmented and virtual reality have been used has been carried out. This study focuses on conducting a thorough scoping review focused on these new technologies, where the evolution of each of them during the last years in the most important categories and in the countries most involved in these technologies will be analyzed. Finally, we will analyze the future trend of these technologies and the areas in which it is necessary to investigate to further integrate these technologies into society.Universidad de Sevilla, Spain Telefonica Chair “Intelligence in Networks
Multimodal fusion : gesture and speech input in augmented reality environment
Augmented Reality (AR) has the capability to interact with the virtual objects and physical objects simultaneously since it combines the real world with virtual world seamlessly. However, most AR interface applies conventional Virtual Reality (VR) interaction techniques without modification. In this paper we explore the multimodal fusion for AR with speech and hand gesture input. Multimodal fusion enables users to interact with computers through various input modalities like speech, gesture, and eye gaze. At the first stage to propose the multimodal interaction, the input modalities are decided to be selected before be integrated in an interface. The paper presents several related works about to recap the multimodal approaches until it recently has been one of the research trends in AR. It presents the assorted existing works in multimodal for VR and AR. In AR, multimodal considers as the solution to improve the interaction between the virtual and physical entities. It is an ideal interaction technique for AR applications since AR supports interactions in real and virtual worlds in the real-time. This paper describes the recent studies in AR developments that appeal gesture and speech inputs. It looks into multimodal fusion and its developments, followed by the conclusion.This paper will give a guideline on multimodal fusion on how to integrate the gesture and speech inputs in AR environment
Hands-free wearable system for helping in assembly tasks in aerospace
Las operaciones de mantenimiento
tienen un gran impacto en la seguridad
y esperanza de vida de cualquier
producto, especialmente en ciertas
aplicaciones dentro de la industria
aeronáutica que tiene que pasar
procedimientos muy rigurosos de
seguridad. Los sistemas de ayuda
llevables (wearable) pueden ayudar
a reducir costes y tiempo de trabajo
guiando a los operarios en tareas
difíciles. El propósito de este trabajo
es presentar un sistema de guiado de
manos libre y llevable para soporte
y ayuda de operarios en tareas de
ensamblaje y verificación dentro del
campo de la aeronáutica. El operario es
capaz de pedir información al sistema
sobre una tarea específica de un modo
no invasivo así como pedir asistencia
técnica al líder del equipo. El sistema
desarrollado ha sido probado en una
compañía aeronáutica (Airbus Military)
y se ha evaluado su implementación
en ciertas tareas de ensamblaje. La
conclusión de las pruebas ha sido
que el sistema ayuda a los operarios a
realizar sus tareas de una manera más
rápida, precisa y segura.Maintenance operations have a great
impact on the safety and life expectancy
of any product. This is especially true
for certain applications within the
aerospace industry, which must pass
rigorous security checking procedures.
Wearable helping systems can help
to reduce costs and working time by
guiding workers in some specifi c and
diffi cult tasks. The purpose of this work
is developing a handless and wearable
guided system that supports and helps
workers in assembly and verifi cation
tasks within the aeronautic fi eld. The
worker is able to request information
for the specifi c task in a non invasive
way and also ask the Team Leader
for real time technical support and
assistance. The system developed has
been tested in an aeronautic company
(Airbus Military) and its implementation
in specifi c assembly tasks assessed. It
was found that the proposed system can
help workers to make their tasks faster,
more accurate and more secure
Cross-Dimensional Gestural Interaction Techniques for Hybrid Immersive Environments
We present a set of interaction techniques for a hybrid user interface that integrates existing 2D and 3D visualization and interaction devices. Our approach is built around one- and two-handed gestures that support the seamless transition of data between co-located 2D and 3D contexts. Our testbed environment combines a 2D multi-user, multi-touch, projection surface with 3D head-tracked, see-through, head-worn displays and 3D tracked gloves to form a multi-display augmented reality. We also address some of the ways in which we can interact with private data in a collaborative, heterogeneous workspace
A case study of augmented reality serious games
The study introduced in this paper examines some of the issues involved in the design and implementation of serious games that make use of tangible AR environments. Our motivation is to understand how augmented reality serious games (ARSG) can be applied to some very difficult problems in the real gaming world. Emphasis is given on the interface and the interactions between the players and the serious games themselves. In particular, two case studies are presented, ARPuzzle and ARBreakout. Results from both case studies indicate that AR gaming has the potential of revolutionizing the way that current games are played and used as well as that it can help educate players while playing

Augmented reality device for first response scenarios
A prototype of a wearable computer system is proposed and implemented using commercial off-shelf components. The system is designed to allow the user to access location-specific information about an environment, and to provide capability for user tracking. Areas of applicability include primarily first response scenarios, with possible applications in maintenance or construction of buildings and other structures. Necessary preparation of the target environment prior to system\u27s deployment is limited to noninvasive labeling using optical fiducial markers. The system relies on computational vision methods for registration of labels and user position. With the system the user has access to on-demand information relevant to a particular real-world location. Team collaboration is assisted by user tracking and real-time visualizations of team member positions within the environment. The user interface and display methods are inspired by Augmented Reality1 (AR) techniques, incorporating a video-see-through Head Mounted Display (HMD) and fingerbending sensor glove.*.
1Augmented reality (AR) is a field of computer research which deals with the combination of real world and computer generated data. At present, most AR research is concerned with the use of live video imagery which is digitally processed and augmented by the addition of computer generated graphics. Advanced research includes the use of motion tracking data, fiducial marker recognition using machine vision, and the construction of controlled environments containing any number of sensors and actuators.

The CD requires the following system requirements: Adobe Acrobat; Microsoft Office; Windows MediaPlayer or RealPlayer
Augmented Reality
Augmented Reality (AR) is a natural development from virtual reality (VR), which was developed several decades earlier. AR complements VR in many ways. Due to the advantages of the user being able to see both the real and virtual objects simultaneously, AR is far more intuitive, but it's not completely detached from human factors and other restrictions. AR doesn't consume as much time and effort in the applications because it's not required to construct the entire virtual scene and the environment. In this book, several new and emerging application areas of AR are presented and divided into three sections. The first section contains applications in outdoor and mobile AR, such as construction, restoration, security and surveillance. The second section deals with AR in medical, biological, and human bodies. The third and final section contains a number of new and useful applications in daily living and learning
