title	Evaluating Relative Impact of Virtual Reality System Variables on Architectural Design Comprehension and Presence - A variable-centered approach using fractional factorial experiment
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 66-73

summary	The relative contributions of five variables (Stereoscopy, screen size, field of view, level of realism and level of detail) of virtual reality systems on spatial comprehension and presence are evaluated here. Using a variable-centered approach instead of an object-centric view as its theoretical basis, the contributions of these five variables and their two-way interactions are estimated through a 25-1 fractional factorial experiment (screening design) of resolution V with 84 subjects. The experiment design, procedure, measures used, creation of scales and indices, results of statistical analysis, their meaning and agenda for future research are elaborated.

title	MULTIMODAL VIRTUAL REALITY ENVIRONMENT FOR ARCHITECTURAL DESIGN (RE)PRESENTATION
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 513-519

summary	The diversity of representations and the complexity of capturing and communicating the design process and its rationale present a challenge to architects. This paper proposes a multimodal virtual reality environment (MVE) aimed at utilizing the inherent advantages of distinct media, as opposed to a stand-alone virtual reality environment. Virtual reality is seen here as one of the tools in the larger milieu of interactive multimedia tools available to architects. The theoretical framework underlying its development explores the role of digital tools in the design process, their adaptability to existing workflow and issues of representation and perception, especially how design ideas are represented, evaluated and manipulated in the mind. The development of MVE followed a cycle of design, usability studies by a focus group and redesign.

title	Capturing Affect in Architectural Visualization - A Case for integrating 3-dimensional visualization and psychophysiology
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 664-669
doi	https://doi.org/10.52842/conf.ecaade.2006.664
summary	Envisioning architectural experience afforded by a building under design has been difficult due to two reasons. One is simulating the space in full scale, eliminating the need to take a mental leap commonly required of abstract smaller scale representations. Second challenge is in fully capturing the affective experience, which is often subtle in nature. This paper suggests that 3-dimensional visualization - particularly immersive virtual reality can overcome the first challenge. In addition, psychophysiological measures such as facial electromyography (EMG) and electrodermal activity (EDA) can be used to capture the affective component of the architectural experience. We suggest that by taking advantage of these technologies together, one can better simulate and empirically understand the nature of architectural experience.
