Using Virtual Reality Tools in Design and Technical Graphics Curricula: An Experience in Learning
Get PDFThis paper presents findings from a project for introducing virtual reality (VR) technology into design and technical graphics curricula. In particular, findings are presented that show how the implementation of VR technology affected and changed pedagogical practices between instructors and students in classrooms at three educational institutions. Classroom observations were obtained from a team of curriculum and instruction professors and graduate students, who provided feedback concerning use of VR technology in the classrooms. Student surveys, both before and after using VR tools, and focus group interviews, were also conducted. Quantitative and qualitative evaluation data was analyzed and used to plan for future use of VR technology. Implementation findings provide insights into how to use VR technology in design and technical graphics education, which can help instructors to effectively introduce the new VR tools in their classrooms
Parallels between Engineering Graphics and Data Visualization: A First Step toward Visualization Capacity Building in Engineering Graphics Design
Get PDFThe definition of visualization in engineering graphics has evolved over the years due in part to extensive research in visualization by the engineering design graphics profes¬sion. The literature indicates research in the areas of engineering graphics and the use of visualization has grown from improvement of visualization skills and the development of visualization tools, to the exploration of spatial ability and perception in engineering graphics. The goals of this paper are three-fold: (1) to provide a high level overview of how the definition of visualization has historically been defined and shaped in engineering graph¬ics, (2) provide an introduction to data visualization as a process, and (3) explore the parallels between the process of visualizing data and the engineering design process as first steps toward visualization capacity building in engineering design
Message from the Chair - Looking for Bright Spots
No full textThis is my last message from the Chair, and I have been thinking about the times we are going through and issues we are facing in this weak economy. Layoffs, furloughs, lack of funds for classroom materials as well as loss of travel funds do not make for lighthearted campuses. For the person without a job, there is not much that is positive, and, even if you have a job, you probably are holding your breath hoping you do tomorrow. I contend, however, that there are some beneficial aspects to this situation, and I would like to mention three. At North Carolina State, our program is losing a full-time and two part-time faculty members, forcing us to rethink the way we provide instruction for students. Since the number of students has not proportionally diminished, we are looking at ways to stretch our resources. To accomplish this, we are experimenting with technologies that can offer more efficient ways of providing the same quality of instruction, since the luxury of teaching reasonably size classes, totally face-to-face, has disappeared. This brings me to my first point. While our students have been “face-booking” and “twittering,” the majority of the faculty has continued to rely on old methods of teaching. Because funds are now tight, instructors who have been unwilling to adopt new technologies may now be forced to think outside the box, to innovate, and to experiment with new teaching and learning strategies to simply survive teaching the number of students who require their courses. In doing so, faculty also have to rethink and reexamine the course’s content and organization to teach the new way, which makes them look closer at the course and the pedagogy involved in moving to a new way of presenting material. With instruction delivered through technology, instructors finally may become the “facilitators of learning” that educators have been talking about for years. Science now understands that evolution in living organisms occur in sudden bursts and not the steady pace earlier postulated. Some of these sudden changes are thought to be due to cataclysmic events. For education this recession could well be a cataclysmic event that forces instructors to move quicker towards mirroring the technological nature of our society, or, at least, the technology the students in our classes are already comfortable with. A second benefit of the recession is we may have greater empathy for our students and what they face as they leave school and hunt for that first job. Students have always left school with a certain amount of anxiety about their future, but over time faculty tend to forget what it feels like to leave the familiar environment they have known for work in the real world. Students in the current economic situation are leaving school with even greater anxiety. As we all are facing uncertain futures at this time, it is easier to relate to their anxieties. A third benefit of the recession is that organizations and administrations that govern our institutions will be streamlined. With tighter budgets, the need to save money will initiate an examination of administrative units, and we will end up, hopefully, with a more efficient administration and organization because there is an incentive to trim the administrative tree. We will survive all of this, and I think we will come out stronger on the other side. Unquestionably, some things will be lost that shouldn’t, but we also have an opportunity to gain in some ways. I guess I am looking hard for bright spots where ever I can find them
Representing the Past by Solid Modeling + Golden Ratio Analysis
Get PDFThis paper describes the procedures of reconstructing ancient architecture using solid modeling with geometric analysis, especially the Golden Ratio analysis. In the past the recovery and reconstruction of ruins required bringing together fragments of evidence and vast amount of measurements from archeological site. Although researchers and scholars in the archeological field have used traditional manual methods to obtain data, the innovative application of solid modeling and geometric analysis techniques can help verify and reveal unknown or uncertain data. This paper demonstrates application of solid modeling with an approach from geometric construction perspective, along with data collection, literature review and photography analysis. Two case studies are demonstrated in this paper. They are the reconstruction of ruined ancient luxury complex Baths of Caracalla and building of a 3D digital model of Florence Cathedral. In addition, several solid models of case studies are presented in the paper
Distortion in Perspective Projection
Get PDFThe paper presents a unique approach in associating perspective projection with the image beheld by the eye and demonstrates that all graphical and photographic perspective projections must contain distortion when compared to the image beheld by the eye
Using Novel 2D Image Manipulation Methods to Aid Initial Concept Generation with Postgraduate Industrial Design Students
Get PDFThe aim of this paper is to provide educators and industrial design professionals with an insight into the development of innovative design ideation images manipulation techniques and, highlight how these techniques could be used to not only improve student ideation skills, but also as design enablers for a broader range of professionals working both inside and outside the creative industries. The review of literature highlights the changing role of the industrial designer through influencing factors such as increased involvement in upstream design activities and the ‘maker movement’. The paper documents research conducted with postgraduate industrial design students in a specific year group within Loughborough Design School. The study is a pilot project with a small cohort of 29 industrial design postgraduate students which will form part of the ongoing pedagogic development of the skills required for the ever evolving discipline of industrial design. The study covers one academic semester, where postgraduate industrial design students were asked to use novel ideation methods to produce a range of aesthetic design directions for a communication device. The results of the research showed significant improvements in ideation workflow, the suitability and quality of the student’s form generation, as well as the perceived quality of the final design outcomes
A Freshman Engineering Design Graphics Collaboratory
Get PDFThis paper briefly reviews the author’s experiences over the past four decades in transforming the Engineering Design Graphics (EDG) curriculum. During this time, the field has seen a remarkable evolution from manual drafting to 3-D computer modeling with its many applications to engineering design and analysis. The paper will further discuss the current status of the EDG curriculum at the author’s homeinstitution. The current concept is an EDG collaboratory space, in which teamwork and a design project are the overarching theme in which graphics and 3-D modeling fundamentals are taught
Differentiating between Spatial Ability as a Specific Rather than General Factor of Intelligence in Performance on Simple, Non-routine Problems in Mathematics
Get PDFSpearman concluded that performance on any test of mental ability could be explained by several cognitive factors organized hierarchically as one general factor and several subordinate specific factors (Spearman, 1904, 1927). The general factor accounted for the significant amount of inter-correlation between all ability tests for any one individual while the specific factor explained the variation that was unique to each test. While there has been much debate in the literature as to what the specific factors are, with many different combinations of number and type of ability, three abilities — verbal, quantita¬tive and spatial –consistently emerge as playing a dominant role in cognition (Kyllonen, 1996)
Integrating Assessment and Design Activity in Engineering Education: A Proposed Synthesis of Adaptive Comparative Judgement and the CDIO Framework
Get PDFOne of the leading frameworks in engineering education specifically associated with design based competencies is the CDIO framework. This has been incorporated internationally into many institutions offering engineering education courses. Characterized by four unique stages, the CDIO framework affords an ideal scenario to incorporate a continuous assessment model. This paper presents a proposed synthesis between CDIO and Adaptive Comparative Judgement (ACJ). In particular, the opportunity to provide feedback through the ACJ system is theorized to have potentially positive educational effects. As part of a larger study, this approach is in the process of being refined prior to implementation as a pilot study for feasibility which will ultimately be succeeded by large-scale implementation to determine any potentially positive effect sizes
