Cognitive presence as a unified concept of virtual reality effectiveness
David Nuñez, Edwin Blake · 2001
We propose a synthesis of two current major approaches to understanding the effectiveness of VR systems. We propose cognitive presence as a single, unified concept of presence which includes previous ideas of presence in a cognitive psychological framework, and propose a methodology for measuring it. We then critically examine the notion of cognitive presence, as a way of conceptualizing HCI quality in virtual environments 1. CURRENT IDEAS OF PRESENCE Presence is currently the focus of much VR research. Many researchers believe that presence can be used as a general measure of VR effectiveness ([21], [10]), and that creating VR systems which increase presence in users will contribute towards better task performance on those systems ([10], [13]). Presence is currently of interest to a wide variety of researcher, ranging from those who are interested in how display technologies are related to presence (for example, [12], [17] and [1]) to those who are interested in the human interface aspects of VR (for example [10],[11], [15] and [19]).
