“…We briefly reviewed papers that varied between examining the space and virtual elements as well as the interaction using AR. From a different perspective, one study highlighted the challenges that might be faced when using AR and their elements to mix reality with virtual reality in acting [9]. Other studies have observed the implantation and impact of A Rexperiences for visitors in museums, whereas another study examined the interaction of a virtual set and dealing with space and virtual elements [10].…”

The latest technological developments continually affect all fields, including through the implementation of augmented reality (AR) in media broadcasting. The use of AR can improve the public image of broadcasting and allow international, national, and regional information and stories to be presented impressively and effectively. Furthermore, AR will allow presenters to interact with television stories through a three-dimensional (3D) virtual environment as well as provide the viewer with rich information about the world. However, undergraduate media departments at most universities in Jordan are still teaching news presentation in basic newsrooms. Therefore, this paper presents an experimental collaboration between the Television Department and Animation & Multimedia Department at the University of Petra; an AR virtual studio and 3D computer graphics animation were used to teach performance skills to students who aim to become television news anchors after graduation. This experimental research provides students with a new approach and tool for storytelling, including techniques to deal with technological evolution in the media field. This paper evaluates the impact of employing virtual worlds in newscasts as an effective method of education delivery for Jordanian students, and also offers suggestions for improving the curricula of radio and television departments. Such improvements will enable media students who are interested in working as presenters or news broadcasters to gain skills and experience in interacting with 3D animated elements. The results of this research revealed that media students and graduates would be more successful in the media industry if they mastered the skills of communication, presentation, and acting performance to interact with virtual environments and virtual 3D animated objects. These skills could lead to improved employment opportunities after graduation. Accordingly, this study aimed to present solutions and motivate universities in Jordan to apply the AR virtual studio as a powerful tool for presenting stories.

“…Two key studies for supporting actor motion in the virtual studio are the work of Kim et al [13] and Woldecke et al [14], [15]. These analyse the effectiveness of using haptic devices to aid actors in locating the surfaces of virtual objects.…”

“…These analyse the effectiveness of using haptic devices to aid actors in locating the surfaces of virtual objects. Kim et al [13] used vibrotactile haptic devices placed in the palm of the actor that vibrated when a collision with a virtual object was detected. While these helped improve the performance of the actor, they were still liable to incorrectly estimate the surface of the virtual object due to a slow response time from the devices.…”

When human actors interact with virtual objects the result is often not convincing to a third party viewer, due to incongruities between the actor and object positions. In this study we aim to quantify the magnitude and impact of the errors that occur in a bimanual interaction, that is when an actor attempts to move a virtual object by holding it between both hands. A three stage framework is presented which firstly captures the magnitude of these interaction errors, then quantifies their effect on the relevant third party audience, and thirdly assesses methods to mitigate the impact of the errors. Findings from this work show that the degree of error was dependent on the size of the virtual object and also on the axis of the hand placement with respect to the axis of the interactive motion. In addition, actor hand placement outside and away from the object surface was found to affect the visual plausibility considerably more than when the actor's hands were within the object boundaries. Finally, a method for automatic adaptation of the object size to match the distance between the actor's hands gave a significant improvement in the viewers' assessment of the scene plausibility.

“…In practice, we set P f to values specific to the data sets. Note however that in a more general approach, P f can evolve during the iterative process, since H B 's evolves, by automatic thresholding as proposed in [32].…”

Abstract-In this paper, we present a method for extracting consistent foreground regions when multiple views of a scene are available. We propose a framework that automatically identifies such regions in images under the assumption that, in each image, background and foreground regions present different color properties. To achieve this task, monocular color information is not sufficient and we exploit the spatial consistency constraint that several image projections of the same space region must satisfy. Combining monocular color consistency constraint with multi-view spatial constraints allows to automatically and simultaneously segment the foreground and background regions in multi-view images. In contrast to standard background subtraction methods, the proposed approach does not require a priori knowledge of the background nor user interaction. Experimental results under realistic scenarios demonstrate the effectiveness of the method for multiple camera setups.
