—Previous attempts to quantify immersion have been pursued within the context of game virtual worlds where there is a clear outline of a goal. This paper seeks to investigate the problem of immersion measurement in an online based virtual world (ReactionGrid) where there is no distinct in-world goal and environmental context is less immersive as in a game(More)
Object shadowing is an established programming concept that is supported by languages such as LPC. Thus far, shadowing in LPC appears to have been driven mainly by pragmatics rather than having followed any particular formal evolutionary path. In this paper, we describe the concept of object shadowing and suggest a number of suitable application areas that(More)
Whilst the object oriented paradigm and its instantiation within programming languages such as Java has become a ubiquitous part of both the commercial and educational landscapes, its usage as a visualisation technique within Mathematics undergraduate programmes of study has perhaps been somewhat underestimated. By regarding the object oriented paradigm as(More)
The modern world increasingly requires us to prove our identity. When this has to be done remotely, as is the case when people make use of web sites, the most popular technique is the password. Unfortunately the profusion of web sites and the associated passwords reduces their efficacy and puts severe strain on users' limited cognitive resources. There is(More)
It is well-known that few object-oriented programming languages allow objects to change their nature at run-time. In this paper we discuss the need for object-oriented programming languages to reflect the dynamic nature of problems, particularly those arising in a mathematical context. It is from this context that we present a framework , together with a(More)
We present an account of an undergraduate team based assignment designed to facilitate, exhibit and record team working skills in an e-mediated environment. By linking the student feedback received to Hofstede's classic model of cultural dimensions we aim to show the assignment's suitability in revealing the student's multi-cultural context. In addition to(More)
Shadows are well known as a programming language feature in the application area of MUDs (a certain type of multi-player online game). We argue that agile methodolo-gies can be enhanced by the use of shadows as this feature because of its inherent ability to dynamically change the behavior of classes and objects, provides mechanisms to ease common tasks(More)
Agile methodologies can be enhanced by the use of shadows as this feature because of its inherent ability to dynamically change the behavior of classes and objects, provides mechanisms to ease common tasks such as prototyping, deprecating , dynamic classification and interclassing at run-time. We feel however that shadows should be considered a notion(More)
We discuss and demonstrate how Virtual Worlds available at the University of Bedfordshire have been used to teach Project Management using a 'situated learning' approach. In particular we have a closer look on the aspect of teaching risk management and identify how different aspects of risk are addressed in a variety of implementations of Virtual Worlds,(More)
