An Affordance-based Framework for CVE Evaluation (2002)
Presentation / Conference Contribution
Turner, P., & Turner, S. (2002). An Affordance-based Framework for CVE Evaluation. In X. Faulkner, J. Finlay, & F. Détienne (Eds.), People and Computers XVI - Memorable Yet Invisible (89-103). https://doi.org/10.1007/978-1-4471-0105-5_6

We argue that a conceptual framework is required to support the practical evaluation of collaborative virtual environments. We propose such a framework based on an extended, three level concept of affordance. The application of the framework is il... Read More about An Affordance-based Framework for CVE Evaluation.

Contextual grounding in CVE design. (2002)
Journal Article
Turner, P., & Turner, S. (2002). Contextual grounding in CVE design. Presence: Teleoperators and Virtual Environments, 14, 30-38

A proper respect for eventual context of use is crucially important for the success of virtual environments destined for real-world organisations, yet is frequently absent from accounts of the design of such applications. We describe how contextual... Read More about Contextual grounding in CVE design..

Presentation / Conference Contribution
Kukla, R., Willis, A., & Kerridge, J. (2002). Application of context-mediated behavior to a multi-agent pedestrian flow model (PEDFLOW).

Developers of pedestrian models often overlook the fact that pedestrians are subjected to a multitude of influences when walking. The majority of existing models only focus on a single aspect, typically the avoidance of obstructions or other pedestri...
