This paper reports on the elicitation of requirements for Virtual Actors in Collaborative Virtual Learning Environments (CVLEs). The methodological approach followed involves the phased development of a series of learning environments which are observed in use by parents, children and teachers. The focus of study is on the interactivity and social(More)
This paper argues that the development of virtual actor technology must be guided by application and end user needs. Two objectives drive the development of the '<i>Senet</i>' project described in this paper: to develop a set of design guidelines for the use of virtual actors in Collaborative Virtual Environments (CVEs) for learning, and to inform the(More)
1. INTRODUCTION This paper describes a collaboration between human factors and technological researchers on the development of Collaborative Virtual Environment (CVE) technology based on application and end user needs. The aim of the research is to develop a framework of design factors for the use of virtual actors in CVEs, and so inform the development of(More)
Inhabiting the virtual city: The design of social environments for electronic communities The goal of this work is to develop an approach to the design of on-line social environments. My thesis is that, in order to foster the development of vibrant and viable online communities, the environment-i.e. the technical infrastructure and user interface-must(More)
Accumulation of amyloid β (Aβ) in brain is a pathological hallmark of Alzheimer's disease (AD). Aβ is generated after sequential cleavage of its parental molecule, amyloid precursor protein (APP), by β- and γ-secretases. Inhibition of γ-secretase activity is an effective approach for the reduction of Aβ levels. Since γ-secretase targets many different(More)
The need for a real-world driving problem to guide technology development has long been recognised. However, this does not guarantee the identification of requirements for technology development. This paper argues that a more systematic approach is needed for choosing and making best use of a driving problem for CVE technology. The method consists of(More)
