Spatial Understanding in Immersive Virtual Environments

Abstract: In this study, we examined the perception and understanding of spatial volumes within immersive and non-immersive virtual environments by comparison with representation using conventional media. We examined the relative effectiveness of these conditions in enabling the translation to a tangible representation, through a series of design experiments. Students experienced, assessed, and analysed spatial relationships of volumes and spaces and subsequently constructed real models of these spaces. The goal of our study is to identify how designers perceive space in Virtual Environments (VEs). We explore issues of quality, accuracy and understanding of reconstructing architectural space and forms. By comparison of the same spatial performance task undertaken within a Head Mounted Display, screen-based and real 2D environment, we are able to draw some conclusions about spatial understanding in immersive VE activity.

A Virtual Community as the Context for Discursive Interpretation: A Role in Cultural Heritage Engagement

Abstract: Increasing recognition is being accorded to the important role of digital media in the management of heritage. Although little explored, there is significant potential for virtual communities to contribute to the interpretation of heritage and engender a sense of place. By way of a case study, the authors examine the theoretical and practical aspects of engaging members of the public in the collection and interpretation of cultural heritage in Hong Kong.

The experience of burnout among future construction professionals: A cross-national study

Abstract: A survey of undergraduate students in Australia and Hong Kong revealed that a specially adapted version of the Maslach Burnout Inventory (the MBI‐SS) possesses good internal consistency reliability among construction students. A three‐component model of student burnout, comprising emotional exhaustion, cynicism and personal efficacy was supported in both the Australian and Hong Kong samples. Burnout levels among construction students were similar to those reported in previous non‐construction student samples. Both Australian and Hong Kong construction students reported higher personal efficacy than non‐construction students. Australian students expressed considerably higher cynicism in relation to their university education than the Hong Kong students. The three dimensions of burnout were differentially correlated with work, study and socio‐economic variables. In Australia, student burnout was associated with a perceived tension between paid work and study. In Hong Kong, the demands of study and concern w...

The First Virtual Environment Design Studio

Abstract: Since 1993 schools of architecture all over the world conduct in various forms of Virtual Design Studio (VDS). They have become an established part of teaching design within the digital realm. They vary in task and structure, are purely text-based or include various forms of interactive, synchronous or asynchronous collaboration. However, ‘virtual’ always refers to the method of communication and exchange of design and ideas. Students have never designed within immersive virtuality. This paper describes the first successful attempt to conduct a Joint Design Studio, which uses Virtual Environment (VE) as tool of design and communication between the remote partners. This first VeDS focused on how architectural students make use of this particular different approach to design within immersive three-dimensional VEs. For example, the students created 3D-immersive design proposals, explored dependencies to textual description of initial intentions and communicated between local and remote team-partners in immersive VE as well as textbased communication-channels. The paper subsequently describes the VeDS, its set-up, realization and outcome. We discuss frameworks and factors influencing how architectural students communicate their proposals in immersive VeDS, and how this new approach of design studio enables new forms of design expressions.

Polymers for 3D Printing and Customized Additive Manufacturing

Abstract: Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining. AM enables decentralized fabrication of customized objects on demand by exploiting digital information storage and retrieval via the Internet. The ongoing transition from rapid prototyping to rapid manufacturing prompts new challenges for mechanical engineers and materials scientists alike. Because polymers are by far the most utilized class of materials for AM, this Review focuses on polymer processing and the development of polymers and advanced polymer systems specifically for AM. AM techniques covered include vat photopolymerization (stereolithography), powder bed fusion (SLS), material and binder jetting (inkjet and aerosol 3D printing), sheet lamination (LOM), extrusion (FDM, 3D dispensing, 3D fiber deposition, and 3D plotting), and 3D bioprinting....

A Review of Additive Manufacturing

Abstract: Additive manufacturing processes take the information from a computer-aided design (CAD) file that is later converted to a stereolithography (STL) file. In this process, the drawing made in the CAD software is approximated by triangles and sliced containing the information of each layer that is going to be printed. There is a discussion of the relevant additive manufacturing processes and their applications. The aerospace industry employs them because of the possibility of manufacturing lighter structures to reduce weight. Additive manufacturing is transforming the practice of medicine and making work easier for architects. In 2004, the Society of Manufacturing Engineers did a classification of the various technologies and there are at least four additional significant technologies in 2012. Studies are reviewed which were about the strength of products made in additive manufacturing processes. However, there is still a lot of work and research to be accomplished before additive manufacturing technologies become standard in the manufacturing industry because not every commonly used manufacturing material can be handled. The accuracy needs improvement to eliminate the necessity of a finishing process. The continuous and increasing growth experienced since the early days and the successful results up to the present time allow for optimism that additive manufacturing has a significant place in the future of manufacturing.
