Virtual Reality Full Immersion Techniques for Enhancing Workers Performance, 20 years Later: A Review and a Reformulation <s> E. Natural User Interfaces (NUI) <s> From the Publisher: ::: This book describes the EyeTap principle developed by the author. EyeTap technology allows non-invasive tapping into the human eye to allow shared vision for multiple parties. This technology will be applied in areas such as long-distance video conferencing. <s> BIB001 </s> Virtual Reality Full Immersion Techniques for Enhancing Workers Performance, 20 years Later: A Review and a Reformulation <s> E. Natural User Interfaces (NUI) <s> Touch and gesturaldeviceshave been hailed as next evolutionary step in human-computer interaction. As software companies struggle to catch up with one another in terms of developing the next great touch-based interface, designers are charged with the daunting task of keeping up with the advances innew technology and this new aspect to user experience design. Product and interaction designers, developers and managers are already well versed in UI design, but touch-based interfaces have added a new level of complexity. They need quick references and real-world examples in order to make informed decisions when designing for these particular interfaces. Brave NUI World is the first practical book for product and interaction developers and designing touch and gesture interfaces. Written by developers of industry-first, multi-touch, multi-user products, this book gives you the necessary tools and information to integrate touch and gesture practices into your daily work, presenting scenarios, problem solving, metaphors, and techniques intended to avoid making mistakes. *Provides easy-to-apply design guidance for the unique challenge of creating touch- and gesture-based user interfaces *Considers diverse user needs and context, real world successes and failures, and a look into the future of NUI *Presents thirty scenarios, giving practitioners a multitude of considerations for making informed design decisions and helping to ensure that missteps are never made again <s> BIB002 </s> Virtual Reality Full Immersion Techniques for Enhancing Workers Performance, 20 years Later: A Review and a Reformulation <s> E. Natural User Interfaces (NUI) <s> The launch of the Microsoft Kinect for Xbox (a real-time 3D imaging device) and supporting libraries spurred the development of various applications including those with natural user interfaces. We propose that using Kinect offers opportunities for novel approaches to classroom instruction on natural user interaction. A number of development frameworks has come up that can be used to facilitate this instruction. We evaluate the current state of this technology and present an overview of some of its development frameworks. We then present examples of how Kinect-assisted instruction can be used to achieve some of the learning outcomes in Human Computer Interaction (HCI) courses as outlined in IT2008. We have verified that OpenNI, with its accompanying libraries, can be used for these activities in multi-platform learning environments. <s> BIB003 </s> Virtual Reality Full Immersion Techniques for Enhancing Workers Performance, 20 years Later: A Review and a Reformulation <s> E. Natural User Interfaces (NUI) <s> Recent developments in user-input technologies are changing the way we interact with digital screens. The mouse and the keyboard are being replaced by touch and motion based interfaces, increasingly known as Natural User Interfaces (NUI). YDreams has developed Yvision, a platform that enables the development of natural user interfaces. YVision has a modular architecture matching YDreams technologies with the best of open source third party libraries. Our technologies emphasize the creation of smart interfaces using autonomous agents that go beyond the traditional reactive systems. Yvision also includes computer vision algorithms for motion detection and the application of 3D depth sensing in rendering engines. NUI applications involve: data acquisition using various sensors that detect the user's motion and gestures; interpretation of sensor data; and presentation, the end visualization layer. YVision includes augmented reality capabilities as a visualization component, where images are captured from the real world and enhanced in real-time with contextual information. Natural user interface applications, developed for both 2D and 3D depth sensing, will be presented for illustrative purposes. Applications include projects developed for clients such as Orange, Coca-Cola, Santander and Nike. Ongoing research projects focusing on digital signage and serious games will be also discussed. <s> BIB004
NUI are those interfaces in which user interaction is natural, common and familiar BIB002 . That is why its design Interaction device prototypes. Source:  implies the use of new devices that allow this interaction, which goes beyond the use of the keyboard and mouse. These new generations of devices allow the use of the software by gestures, touch, body movement, voice, etc. Examples of NUI devices are Kinect BIB003 ,  , that copy the movements of the body and send them to a virtual avatar. This device allows the user to control the application without requiring another peripheral, because it also allows voice recognition for command interpretation. The great utility of using NUI is that they are intuitive and easy to handle. For example, for nonnative digital people, learning how to use the mouse is quite complicated, but using Kinect is relatively easy for any user. It is this ease of use which is desired in any user interface, but NUI should not be applied to any application; for example, it would be difficult to use Kinect to operate a word processor. The recent development of input peripherals is changing the way of interaction with digital screens, the mouse and keyboard, and these are being replaced by tactile interfaces based on body movement BIB004 . These new ways of interacting are part of the evolution of the interfaces, which throughout the history of computing have evolved, changed and diversified. The term NUI was coined by Mann BIB001 , who explores new forms of computer human interaction, emerging a variety of investigations that focus on new fields of application. Finally, the NUI, constitute a revolution in the world of computing, not because they will replace the existing and widely used traditional interfaces, but because they enable the creation of new types of applications and new forms of original and novel interactions liable to be applied in Production, Administration, Marketing, etc. (IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 10, 2019 F. Natural Devices Interaction Fig. 3 show the main devices necessary for the creation of NUI. Kinect (Fig. 3(a) ), is the first to appear in the market, created for entertainment purposes for games controlled through transduction, but then used for more advanced applications. Nimble (Fig. 3(b) ), focuses only on hand recognition. Manus (Fig. 3(c) ), unlike the others, uses motion sensors built into gloves. (a) (b) (c) Fig. 3 . Natural Devices Interaction.
