High Quality Content by WIKIPEDIA articles! A graphical user interface (GUI) is a type of user interface item that allows people to interact with programs in more ways than typing such as computers, hand-held devices such as MP3 Players, Portable Media Players or Gaming devices, household appliances and office equipment with images rather than text commands. A GUI offers graphical icons, and visual indicators, as opposed to text-based interfaces, typed command labels or text navigation to fully represent the information and actions available to a user. The actions are usually performed through direct manipulation of the graphical elements. The term GUI is historically restricted to the scope of two-dimensional display screens with display resolutions capable of describing generic information, in the tradition of the computer science research at Palo Alto Research Center (PARC). The term GUI earlier might have been applicable to other high-resolution types of interfaces that are non-generic, such as videogames, or not restricted to flat screens, like volumetric displays.
High Quality Content by WIKIPEDIA articles! A Volumetric Haptic Display (VHD) is similar to a (visual) Volumetric Display, but informs touch instead of vision. A VHD projects a touch-based representation of a surface onto a 3D volumetric space. Users can feel the projected surface(s), usually with their hands. The display is otherwise not detectable, and offers no visual feedback. There are no known instances of a fully operational VHD at this time.At this time, there is no set method to implement VHDs, but it is likely that a wired glove will be used. Methods of projecting the tactile information into space are still being developed.
High Quality Content by WIKIPEDIA articles! A volumetric display device is a graphical display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3-D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space. Though there is no consensus among researchers in the field, it may be reasonable to admit holographic and highly multiview displays to the volumetric display family if they do a reasonable job of projecting a three-dimensional light field within a volume.Most, if not all, volumetric 3-D displays are autostereoscopic, that is, they create 3-D imagery visible to the unaided eye.
The book complements the authors' previously published book titled: "Spatial Visualization Via Real Time 3D Volumetric Display Technologies". It is beneficial and could be of interest to specialists in the fields of constructing 3D computer graphics systems, image synthesis and processing, virtual and extended reality, computer games, multipurpose simulators, identification systems, monitoring, and visual 3D computer modeling in various fields. It is useful for graduate students and senior undergraduate students of computer science and engineering.
The book is beneficial and interesting for researchers working in the field of developing information imaging display systems and real-time visualization environment systems. It is intended for graduate students and researchers in the fields of computer science and engineering. The book is mainly composed of 3 chapters. The first one considers problems with respect to realization of realistic visualization by means of 3D display technology, analysis of devices for 3D display in 3D context and the main trends of their development, methods for 3D visualization organization and methods for 3D visualization units' generation of images. The second chapter presents the development of existing methods for 3D visualization for 3D scenes by means of 3D display technologies. It also reviews methods for realization of realistic stereo 3D visualization and voxel 3D visualization for 3D primitives and scenes. The third chapter describes the possibilities of supporting parallel architectures-based methods and synchronized computing systems to increase the performance and the quality of 3D visualization realization and offers approaches to its organization through 3D display technologies.
In the scope of this thesis we present a working system that allows for hybrid 3D reconstruction for geometry-based Free Viewpoint Video. The primary building block of the system framework is a multi-projector multi-camera array that performs real-time 3D reconstruction based on the principle of phase shifted structured light. Additionally utilizing disparity information generated from two separate color camera pairs for image guided phase unwrapping in a hybrid fashion increases the overall system performance, namely reconstruction accuracy and framerate. The array is comprised of six cameras and two projectors in total. For these, an automated calibration procedure has been developed, which allows for fast repositioning and recalibration of the cameras and the projectors. We present an efficient way to effectively remove or conceal remaining errors in the 3D reconstruction once the geometry-based imagery is rendered for Free Viewpoint Video synthesis. For additional improvement of the final video quality the dynamic 3D data generated with the real-time system is combined with a highly accurate static background model of the scene. We compare a multitude of 3D scanning, 3D rendering and 3D display technologies. Our system is able to accommodate all of the later, including stereoscopic, auto-stereoscopic, volumetric and even future holographic displays. In order to realize immersive Free Viewpoint Video in the absence of available large scale full parallax holographic displays, we have developed a compact head tracking framework. This framework calculates the head position of a single person or viewer relative to the display and renders the 3D data onto this display so it appears as if the viewer sees the scene not on a flatscreen display but that he sees it through an actual real world window.
