Localization And Mapping

Augmented reality (AR) is an emerging technology that allows users to interact with simulated environments, including those emulating scenes in the real world. Most current AR technologies involve the placement of virtual objects within these scenes. However, difficulties in modeling real-world objects greatly limit the scope of the simulation, and thus the depth of the user experience. In this study, we developed a process by which to realize virtual environments that are based entirely on scenes in the real world. In modeling the real world, the proposed scheme divides scenes into discrete objects, which are then replaced with virtual objects. This enables users to interact in and with virtual environments without limitations. An RGB-D camera is used in conjunction with simultaneous localization and mapping (SLAM) to obtain the movement trajectory of the user and derive information related to the real environment. In modeling the environment, graph-based segmentation is used to segment point clouds and perform object segmentation to enable the subsequent replacement of objects with equivalent virtual entities. Superquadrics are used to derive shape parameters and location information from the segmentation results in order to ensure that the scale of the virtual objects matches the original objects in the real world. Only after the objects have been replaced with their virtual counterparts in the real environment converted into a virtual scene. Experiments involving the emulation of real-world locations demonstrated the feasibility of the proposed rendering scheme. A rock-climbing application scenario is finally presented to illustrate the potential use of the proposed system in AR applications.

Augmented reality is an interactive experience of a real-world environment where the objects or images that reside within the world are enhanced or supplemented by computer-generated perceptual information. Augmented Reality adds a thing to the existing world. It is an enhancement to the real world where we mix the real world with the virtual objects. In this paper, we are proposing a methodology that builds a preview of the virtual watch object alongside the real environment. Using this methodology users can place the virtual watch on their wrist and visualize it in their personal space. This eventually reduces the challenging task of walking into a showroom and trying different watches, as the user gets a clear preview before purchasing the actual item. This methodology is best suited for this technology-driven environment.

The method presented in this work reduces the frequency of virtual objects incorrectly occluding real-world objects in Augmented Reality (AR) applications. Current AR rendering methods cannot properly represent occlusion between real and virtual objects because the objects are not represented in a common coordinate system. These occlusion errors can lead users to have an incorrect perception of the environment around them when using an AR application, namely not knowing a real-world object is present due to a virtual object incorrectly occluding it and incorrect perception of depth or distance by the user due to incorrect occlusions. The authors of this paper present a method that brings both real-world and virtual objects into a common coordinate system so that distant virtual objects do not obscure nearby real-world objects in an AR application. This method captures and processes RGB-D data in real-time, allowing the method to be used in a variety of environments and scenarios. A case study shows the effectiveness and usability of the proposed method to correctly occlude real-world and virtual objects and provide a more realistic representation of the combined real and virtual environments in an AR application. The results of the case study show that the proposed method can detect at least 20 real-world objects with potential to be incorrectly occluded while processing and fixing occlusion errors at least 5 times per second.

As If

Augmented reality is defined as the technology in which virtual objects are blended with the real world and also interact with each other. Although augmented reality applications are used in many areas, the most important of these areas is the field of education. AR technology allows the combination of real objects and virtual information in order to increase students’ interaction with physical environments and facilitate their learning. Developing technology enables students to learn complex topics in a fun and easy way through virtual reality devices. Students interact with objects in the virtual environment and can learn more about it. For example; by organizing digital tours to a museum or zoo in a completely different country, lessons can be taught in the company of a teacher as if they were there at that moment. In the light of all these, this study is a compilation study. In this context, augmented reality technologies were introduced and attention was drawn to their use in different fields of education with their examples. As a suggestion at the end of the study, it was emphasized that the prepared sections should be carefully read by the educators and put into practice in their lessons. In addition it was also pointed out that it should be preferred in order to communicate effectively with students by interacting in real time, especially during the pandemic process.

AbstractIn “The Virtual and the Real,” David Chalmers argues that there is an epistemic and ontological parity between VR and ordinary reality. My argument here is that, whatever the plausibility of these claims, they provide no basis for supposing that there is a similar parity of value. Careful reflection upon certain aspects of the transition that individuals make from interacting with real-world, physical environments to interacting with VR provides a basis for thinking that, to the extent that there are good reasons to deny the reality of virtual objects, there are also reasons to place a correspondingly higher value upon the experience of interacting with a VR environment. Chalmers’ assumption to the contrary arises from a subtle misrepresentation of how the phenomenon of cognitive penetration works in the perception of virtual objects, and from an unwillingness to acknowledge how our attitudes toward virtual environments are conditioned by the values we adopt when engaged in gameplay.

Distances in virtual environments (VEs) viewed on a head-mounted display (HMD) are typically underperceived relative to the intended distance. This paper presents an experiment comparing perceived egocentric distance in a real environment with that in a matched VE presented in the Oculus Quest and Oculus Quest 2. Participants made verbal judgments and blind walking judgments to an object on the ground. Both the Quest and Quest 2 produced underperception compared to the real environment. Verbal judgments in the VE were 86\% and 79\% of real world judgments in the Quest and Quest 2, respectively. Blind walking judgments were 78% and 79% of real world judgments in the Quest and Quest 2, respectively. This project shows that significant underperception of distance persists even in modern HMDs.
