Immersive Technologies

Virtual environments and immersive technologies are growing in popularity for human factors purposes. Whether it is training in a low-risk environment or using simulated environments for testing future automated vehicles, virtual environments show promise for the future of our field. The purpose of this session is to have current human factors practitioners and researchers demonstrate their immersive technologies. This is the eighth iteration of the “Me and My VE” interactive session. Presenters in this session will provide a brief introduction of their virtual reality, augmented reality, or virtual environment work before engaging with attendees in an interactive demonstration period. During this period, the presenters will each have a multimedia display of their immersive technology as well as discuss their work and development efforts. The selected demonstrations cover issues of designing immersive interfaces, military and medical training, and using simulation to better understand complex tasks. This includes a mix of government, industry, and academic-based work. Attendees will be virtually immersed in the technologies and research presented allowing for interaction with the work being done in this field.

Virtual Resources

Technological advancements have provided heritage with new learning environments via the use of virtual and augmented reality, which can foster the accessibility and understanding of culture and propose new ways of interacting with heritage. Therefore, in this study, a systematic evaluation is carried out of n=197 heritage education programs listed in the database of the Observatorio de Educación patrimonial en España (OEPE) (the Spanish Heritage Education Observatory–SHEO) which, in their descriptions, integrate the use of virtual environments and/or augmented reality to promote learning on the part of the user. The objectives of this study are: (1) to analyse the state of the art, (2) to evaluate the quality of their educational designs via the “analysis and assessment sequential method for heritage education programs” (SAEPEP-OEPE) and (3) to identify variables which can be improved or which have a significant influence on the quality of the programs. Highlights of the results include: (a) the increasing implementation of these technologies in heritage education programs, with the greater presence of virtual resources than of learning environments, (b) the low level of the scope of educational quality in their designs, particularly their assessment, and (c) the inclusion of advanced technologies slightly decreases the specificity of the educational design.

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.

Interface Metaphor

This paper introduces the Spatially Extended Anchoring Mechanism (SEAM) as a 3-D user-interface metaphor to connect virtual worlds and manage scalability in distributed virtual environments. SEAMs provide a visual and navigable connection between worlds to manage both the complexity of rendering and network communication typically occurring in such environments. In the context of augmented reality, SEAMs can be applied as a 3-D window interface. A rendering algorithm is described which performs well on the graphics accelerators of standard personal computers.
