Virtualsite: an Interface for Accessing Learning Resources

Abstract

Virtual site is an on-line construction resource which enables users to interrogate photo-realistic, three-dimensional, virtual construction objects and to explore linked panoramic scenes using a computer mouse or keyboard. The web-site (and hybrid CDROM) caters for children who are curious to know more about the construction process, for young people considering a career in the industry and for students in Higher Education reading for a construction-related award. Hence, Virtual site appeals to a wide variety of users, providing a vibrant and novel source of multi-media teaching and learning resources. Nodes embedded in panoramic scenes, via Realviz Stitcher, QuickTimeVR (QTVR) and VRWorx, allow learning resources e.g. construction details, careers information and URLs, to be accessed directly from the site. Moreover, QuickTime multi-row object movies give the illusion of being able to "hold" various items of equipment and construction materials. The case study illustrates the key stages in the development of QTVR movies and describes how directional sound can be added in order to create a stimulating and interactive environment. Whilst Virtual site is a HEFCE funded project, which can offer a range of teaching and learning opportunities in Higher Education Institutions, this case study concludes that the concept and technologies underpinning this project have widespread use beyond construction-related education. Examples of QTVR movies can be found in areas as diverse as property, design and experimental research. Accordingly, potential applications depend very much upon the client's needs and the skills of the system developer.
