The significance of practical experience and visualization in the fluid power discipline, highly tied to students’ success, requires integrating immersive pedagogical tools for enhanced course delivery, offering real-life industry simulation. This study investigates the impact of using virtual reality (VR) technology as an instructional tool on the learning and engagement of 48 mechanical engineering technology (MET) students registered in the MET: 230 Fluid Power course at Purdue University. An interactive VR module on hydraulic grippers was developed utilizing the constructivist learning theory for MET: 230 labs, enabling MET students to explore light- and heavy-duty gripper designs and operation through assembly, disassembly, and testing in a virtual construction environment. A survey consisting of a Likert scale and short-answer questions was designed based on the study’s objective to evaluate the students’ engagement and perceived attitude toward the module. Statistical and natural language processing (NLP) analyses were conducted on the students’ responses. The statistical analysis results revealed that 97% of the students expressed increased excitement, over 90% reported higher engagement, and 87% found the VR lab realistic and practical. The NLP analysis highlighted positive themes such as “engagement”, “valuable experience”, “hands-on learning”, and “understanding”, with over 80% of students endorsing these sentiments. These findings will contribute to future efforts aimed at improving fluid power learning through immersive digital reality technologies, while also exploring alternative approaches for individuals encountering challenges with such technologies.

Augmented Reality Computer-aided Design Education (ARCADE) Tool to Improve Student Motivation, Engagement, and Spatial Cognition
Immersive technologies such as Virtual Reality (VR) and Augmented Reality (AR) have become the worldwide huge technological innovations impacting human life significantly. While the VR is an enclosed environment separated completely from the real world, AR allows users to merge the digital and physical worlds and enable the interaction between them. The wide usage of AR has led researchers to investigate its potential capability in several areas including STEM-related fields. Previous research shows that AR assisted courses tend to enhance students’ learning, spatial cognition, increase the students’ motivation and engagement in the learning process. In this study, the researchers have developed an AR application to assist students with spatial cognition and remote course engagement independently. The ARCADE tool enables students to not only visualize the isometric product from its orthogonal views, but it also provides short tutorial clips on how a specific feature was developed and what tools were used. The students can perform basic modifications on the 3D part in the ARCADE such as section views, details views, scale, rotate and explode the assembly views. Although this project is a work in progress, the preliminary pretest and posttest results show there is a significant improvement in students’ spatial cognition when the proposed tool is used to assist the course.

Traditional lectures have difficulties instilling pragmatic skills in construction engineering students due to the inability to illuminate the complexities within the human-robot collaborative construction environment. While on-site can acclimatize construction students to reality and construct knowledge that can solve safety challenges, it is challenging to organize on-site training trips owing to the dangerous nature of construction workplaces. This research aimed to explore virtual reality (VR) as a tool to enhance students’ perception and knowledge of construction robotic safety. For this purpose, the study developed a virtual training platform for providing construction engineering students with safety knowledge on interacting with simulated robots within the virtual environment of construction sites. A self-assessment approach was leveraged among 20 recruited students to demonstrate the efficacy of students’ engagement and learning outcomes from the proposed learning approach over the traditional learning approach. Results indicated a statistical difference in students’ learning outcomes and engagement levels between the developed approach and the traditional approach. Findings demonstrated the implications of VR as an experiential tool to enhance the students’ learning of robotic safety in construction.more » « less

Architectural Engineering (AE) programs typically offer programs of study in at least two subdisciplines that relate to building design and construction. AE students may struggle to select a subdiscipline due to their low exposure and engagement with topics that would inform their decision. Previous research indicates that the immersive nature of virtual and augmented reality (VR/AR) can increase students’ engagement and motivation regarding course content and discipline decisions. The purpose of this study was to investigate the impact of a pilot browser-based virtual reality intervention on first-year AE students’ understanding of the AE subdisciplines and choice for future study, with particular attention to demographic subgroup differences. This pilot was a testbed for a larger set of Virtual/Augmented-Reality-Based Discipline Exploration Rotations (VADERs), which are instructional modules that engage students in authentic AE tasks. In Fall 2020, the pilot VADER-1 module was incorporated into first-year AE courses at one R1 university and one R2 historically black university. This module encouraged students to explore AE subdisciplines through the virtual design of a clinic. Pre-post intervention surveys were used to investigate change in students’ understanding of AE and its subdisciplines. Students reported that their subdiscipline understanding increased significantly. Further, 74% of students reported an increase in their confidence in their choice, and over 30% of students changed their top subdiscipline choice. Some slight differences between demographic subgroups were found. VR/AR interventions hold promise for providing AE students with needed exposure to the practice of the discipline and its subdisciplines.more » « less

This paper explains the design of a prototype desktop and augmented Virtual Reality (VR) framework as a medium to deliver instructional materials to the students in an introductory computer animation course. This framework was developed as part of a Teaching Innovation Grant to propose a cost-effective and innovative instructional frameworks to engage and stimulate students. Desktop-based virtual reality presents a 3-dimensional (3D) world using the display of a standard desktop computer available in most of the PC labs on campus. This is a required course at this university that has students not only from the primary department, but from other colleges/departments as well. Desktop VR has been chosen as a medium for this study due to the ease-of-access and affordability; this framework can be visualized and accessed with the available computers in PC labs available in university campuses. The proposed research is intended to serve as a low-cost framework that can be accessed by all students. The concepts of ‘computer graphics, modeling & animation’, instead of being presented using conventional methods such as notes or power point presentations, are presented in an interactive manner on a desktop display. This framework allows the users to interact with the objects on the display not only via the standard mouse and keyboard, but also using multiple forms of HCI such as Touchscreen, Touchpad, and 3D Mouse. Hence, the modules were developed from scratch for access via regular desktop PCs. Such a framework helps effective pedagogical strategies such as active learning (AL) and project-based learning (PBL), which are especially relevant to a highly lab-oriented course such as this course titled ‘Introduction to Animation’. Finally, the framework has also been tested on a range of VR media to check its accessibility. On the whole, this proposed framework can be used to not only teach basic modeling and animation concepts such as spatial coordinates, coordinate systems, transformation, and parametric curves, but it is also used to teach basic graphics programming concepts. Hence, instead of a touchscreen, the modules have to be developed from scratch for access via regular desktop PCs. Such a framework helps effective pedagogical strategies such as active learning (AL) and project-based learning (PBL), which are especially relevant to a highly lab-oriented course such as this animation course.more » « less

Researchers in interactive information retrieval (IIR) have studied and refined 2D presentations of search results for years. Recent advances are bringing augmented reality (AR) and virtual reality (VR) to real-world systems, though the IIR community has done relatively little work to explore and understand aspects of 3D presentations of search results, effects of immersive environments, and the impacts of spatial cognition and different spatial arrangements of results displays in 3D. In the research proposed here, I outline my plan to use immerse environments to investigate how users’ spatial cognition may influence the information retrieval process. Specifically, this work will observe how spatial arrangements of search results affect users’ ability to find information in the postquery, visual search phase of the IIR process across quantitative and qualitative measures.more » « less
