   Like many natural sciences, a critical component of archaeology is field work. Despite its importance, field opportunities are available to few students for financial and logistical reasons. With little exposure to archaeological research, fewer students are entering archaeology, particularly minority students (Smith 2004; Wilson 2015). To counter these trends, we have leveraged the ongoing revolution in consumer electronics for the current, digitally-empowered generation by creating a game-based, virtual archaeology curriculum to 1) teach foundational principles of a discipline that is challenging to present in a traditional classroom by using sensory and cognitive immersion; and, 2) allow wider access to a field science that has previously been limited to only select students. Virtual reality (VR) is computer technology that creates a simulated three-dimensional world for a user to experience in a bodily way, thereby transforming data analysis into a sensory and cognitive experience. Using a widely-available, room-scale, VR platform, we have created a virtual archaeological excavation experience that conveys two overarching classroom objectives: 1) teach the physical methods of archaeological excavation by providing the setting and tools for a student to actively engage in field work; and, 2) teach archaeological concepts using a scientific approach to problem solving by couching them within a role-playing game. The current prototype was developed with the HTC Vive VR platform, which includes a headset, hand controllers, and two base stations to track the position and orientation of the user’s head and hands within a 4x4 meter area. Environments were developed using Unreal Engine 4, an open source gaming engine, to maximize usability for different audiences, learning objectives, and skill levels. Given the inherent fun of games and widespread interest in archaeology and cultural heritage, the results of this research are adaptable and applicable to learners of all ages in formal and informal educational settings.

2. Virtual Reality: A Learning Tool for Promoting Learners’ Engagement in Engineering Technology

   Azzam, Israa ; Breidi, Farid ; Soudah, Peter. ( June 2023 , ASEE annual conference exposition)

   Engineering education aims to create a learning environment capable of developing vital engineering skill sets, preparing students to enter the workforce and succeed as future leaders. With all the rapid technological advancements, new engineering challenges continuously emerge, impeding the development of engineering skills. This insufficiency in developing the required skills resulted in high regression rates in students’ GPAs, resulting in industries reporting graduates’ unsatisfactory performance. From a pedagogical perspective, this problem is highly correlated with traditional learning methods that are inadequate for engaging students and improving their learning experience when adopted alone. Accordingly, educators have incorporated new learning methodologies to address the pre-defined problem and enhance the students’ learning experience. However, many of the currently adopted teaching methods still lack the potential to expose students to practical examples, and they are inefficient among engineering students, who tend to be active learners and prefer to use a variety of senses. To address this, our research team proposes integrating the technology of virtual reality (VR) into the laboratory work of engineering technology courses to improve the students’ learning experience and engagement. VR technology, an immersive high-tech media, was adopted to develop an interactive teaching module on hydraulic gripper designs in a VR construction-like environment. The module aims to expose engineering technology students to real-life applications by providing a more visceral experience than screen-based media through the generation of fully computer-simulated environments in which everything is digitized. This work presents the development and implementation of the VR construction lab module and the corresponding gripper designs. The virtual gripper models are developed using Oculus Virtual Reality (OVR) Metrics Tool for Unity, a Steam VR Overlay utility created to make visualizing the desktop in a VR setting simple and intuitive. The execution of the module comprises building the VR environment, designing and importing the gripper models, and creating a user-interface VR environment to visualize and interact with the model (gripper assembly/mechanism testing). Besides the visualization, manipulation, and interaction, the developed VR system allows for additional features like displaying technical information, guiding students throughout the assembly process, and other specialized options. Thus, the developed interactive VR module will serve as a perpetual mutable platform that can be readily adjusted to allow future add-ons to address future educational opportunities.

3. Virtual Reality Laboratory Experiences for Electricity and Magnetism Courses

   Ilie, R. ( July 2021 , 2021 ASEE Virtual Annual Conference Content Access)

   A solid understanding of electromagnetic (E&M) theory is key to the education of electrical engineering students. However, these concepts are notoriously challenging for students to learn, due to the difficulty in grasping abstract concepts such as the electric force as an invisible force that is acting at a distance, or how electromagnetic radiation is permeating and propagating in space. Building physical intuition to manipulate these abstractions requires means to visualize them in a three-dimensional space. This project involves the development of 3D visualizations of abstract E&M concepts in Virtual Reality (VR), in an immersive, exploratory, and engaging environment. VR provides the means of exploration, to construct visuals and manipulable objects to represent knowledge. This leads to a constructivist way of learning, in the sense that students are allowed to build their own knowledge from meaningful experiences. In addition, the VR labs replace the cost of hands-on labs, by recreating the experiments and experiences on Virtual Reality platforms. The development of the VR labs for E&M courses involves four distinct phases: (I) Lab Design, (II) Experience Design, (III) Software Development, and (IV) User Testing. During phase I, the learning goals and possible outcomes are clearly defined, to provide context for the VR laboratory experience, and to identify possible technical constraints pertaining to the specific laboratory exercise. During stage II, the environment (the world) the player (user) will experience is designed, along with the foundational elements, such as ways of navigation, key actions, and immersion elements. During stage III, the software is generated as part of the course projects for the Virtual Reality course taught in the Computer Science Department at the same university, or as part of independent research projects involving engineering students. This reflects the strong educational impact of this project, as it allows students to contribute to the educational experiences of their peers. During phase IV, the VR experiences are played by different types of audiences that fit the player type. The team collects feedback and if needed, implements changes. The pilot VR Lab, introduced as an additional instructional tool for the E&M course during the Fall 2019, engaged over 100 students in the program, where in addition to the regular lectures, students attended one hour per week in the E&M VR lab. Student competencies around conceptual understanding of electromagnetism topics are measured via formative and summative assessments. To evaluate the effectiveness of VR learning, each lab is followed by a 10-minute multiple-choice test, designed to measure conceptual understanding of the various topics, rather than the ability to simply manipulate equations. This paper discusses the implementation and the pedagogy of the Virtual Reality laboratory experiences to visualize concepts in E&M, with examples for specific labs, as well as challenges, and student feedback with the new approach. We will also discuss the integration of the 3D visualizations into lab exercises, and the design of the student assessment tools used to assess the knowledge gain when the VR technology is employed.

   Virtual Access to STEM Careers (VASC) is a technology-rich, inquiry and problem-based curriculum designed to expose and stimulate student interest in marine, environmental, computer, and geological sciences. Intended for 3rd through 5th grade students, VASC builds academic momentum at the intermediate level to prepare students for STEM opportunities later in middle school and high school. Our program is aligned with “Next Generation Science Standards” and “Common Core State Standards” and immerses students in rigorous, high-interest learning modules where students are introduced to and take on the roles of different STEM occupations. We are specifically developing and testing virtual reality-based modules that place students in a coastal environment where they learn about the sea turtle life-cycle. Students also practice the types of measurements and conservation tasks that park rangers and marine scientists regularly perform. The investigations focused on the design of a user interface that meets the needs of students and their teachers. We collected feedback on user interface design and knowledge gained by the users from the simulation. Additionally, we compared two different virtual reality head-mounted displays; i) HTC Vive and ii) Oculus Quest 2, to identify the pros and cons of each technology in future classroom settings. Our investigations yielded valuable information about how instructions should be presented to users, how the interface should provide immediate feedback for user error, how surveys should be administered, what equipment is most efficient for transporting and setting up large scale experiments in schools, and what types of interactions students and teachers want to experience in VASC.

5. Survey of Annotations in Extended Reality Systems

   https://doi.org/10.1109/TVCG.2023.3288869  

   Borhani, Zahra ; Sharma, Prashast ; Ortega, Francisco R. ( June 2023 , IEEE Transactions on Visualization and Computer Graphics)

   Annotation in 3D user interfaces such as Augmented Reality (AR) and Virtual Reality (VR) is a challenging and promising area; however, there are not currently surveys reviewing these contributions. In order to provide a survey of annotations for Extended Reality (XR) environments, we conducted a structured literature review of papers that used annotation in their AR/VR systems from the period between 2001 and 2021. Our literature review process consists of several filtering steps which resulted in 103 XR publications with a focus on annotation. We classified these papers based on the display technologies, input devices, annotation types, target object under annotation, collaboration type, modalities, and collaborative technologies. A survey of annotation in XR is an invaluable resource for researchers and newcomers. Finally, we provide a database of the collected information for each reviewed paper. This information includes applications, the display technologies and its annotator, input devices, modalities, annotation types, interaction techniques, collaboration types, and tasks for each paper. This database provides a rapid access to collected data and gives users the ability to search or filter the required information. This survey provides a starting point for anyone interested in researching annotation in XR environments.
