Investigation of impact of Augmented Reality Technology on Interactive Teaching Learning Process

Augmented Reality (AR) is growing technology that superimpose 3D images onto real world. This enhances the user’s real-world experience. This potential of AR can be utilized effectively in teaching learning for engineering graphics course.There is visualization limitation for engineering students entering in first year, and this leads them to face difficulty in understanding and developing orthographic, isometric and section view of models. AR can empower the students to visualize the actual virtual object in 3D view to match their imagination with augmented object. In this regard initially a framework of AR is conceptualized for the course of engineering graphics & an AR application is developed. This paper mainly focuses on investigation & impact of AR technology on interactive teaching learning process in engineering graphics. Impact of this technology is measured by student’s performance in AR interactive test. The result shows increase in student’s performance in written test by 18.52% in engineering graphics and in mental rotation test by 28.97%.

EVM: An Educational Virtual Reality Modeling Tool; Evaluation Study with Freshman Engineering Students

Educational Virtual Modeling (EVM) is a novel VR-based application for sketching and modeling in an immersive environment designed to introduce freshman engineering students to modeling concepts and reinforce their understanding of the spatial connection between an object and its 2D projections. It was built on the Unity 3D game engine and Microsoft’s Mixed Reality Toolkit (MRTK). EVM was designed to support the creation of the typical parts used in exercises in basic engineering graphics courses with a special emphasis on a fast learning curve and a simple way to provide exercises and tutorials to students. To analyze the feasibility of using EVM for this purpose, a user study was conducted with 23 freshmen and sophomore engineering students that used both EVM and Trimble SketchUp to model six parts using an axonometric view as the input. Students had no previous experience in any of the two systems. Each participant went through a brief training session and was allowed to use each tool freely for 20 min. At the end of the modeling exercises with each system, the participants rated its usability by answering the System Usability Scale (SUS) questionnaire. Additionally, they filled out a questionnaire for assessment of the system functionality. The results demonstrated a very high SUS score for EVM (M = 92.93, SD = 6.15), whereas Trimble SketchUp obtained only a mean score of 76.30 (SD = 6.69). The completion time for the modeling tasks with EVM showed its suitability for regular class use, despite the fact that it usually takes longer to complete the exercises in the system than in Trimble SketchUp. There were no statistically significant differences regarding functionality assessment. At the end of the experimental session, participants were asked to express their opinion about the systems and provide suggestions for the improvement of EVM. All participants showed a preference for EVM as a potential tool to perform exercises in the engineering graphics course.

Research of methods of simulation computer modeling and visualization of complex technological processes at the Department of Engineering Graphics and Design of NRU MIET

The article provides an overview of the topics of bachelor’s and master’s design studies of the Department of Engineering Graphics and Design of NIU MIET. The research results are analyzed. Based on the analysis, recommendations are given regarding the implementation of virtual production spaces and technological equipment, the choice of interactive visualization technology, the development of an effective workflow from a three-dimensional model to an interactive module as part of a VR application, the development of layouts and interface templates.

End-to-end design training: from descriptive geometry to computer modeling of cutting tools

Modern trends in the development of technology are based mainly on successful engineering activities. The combination of the most modern computer technologies and the traditions of using a pencil, drawing, drafts, and, of course, a living fruitful thought is a guarantee of the education of a genuine Engineer. On the one hand, educational technologies in engineering universities at the initial stage should be based, in our deep conviction, on school geometry. On the other hand, descriptive geometry and engineering graphics should contain examples for immersion in the chosen specialty. By order of the Ministry of Education and Science of the Russian Federation, engineering classes, in which lecturers of technical universities were involved, were organized 10 years ago in Moscow schools. The creation of engineering classes is caused by the need to instill in students an interest in the engineering profession. To successfully solve this problem, it is necessary to increase the level of students» knowledge in geometry and drawing. On the basis of these subjects, one should develop design skills and skills of using computer modeling tools. The result of this cooperation should be the involvement of schoolchildren to participate in competitions and olympiads. The Department of Engineering Graphics, Bauman Moscow State Technical University, has accumulated 30 years of experience in cooperation with specialized schools in order to develop students» interest in the engineering profession. The article provides an example of the introduction of a common cutting tool, i. e. a drill, which demonstrates the depth of engineering thought formed over a thousand-year history, into the educational process when studying geometry at school and descriptive geometry at a technical university. The drill as an object comprehensible to first-year students is used to provide the basic knowledge of descriptive geometry. In addition, the problem related to the improvement of the technology of end-to-end training throughout the course of obtaining an engineering education is touched upon.
