Evaluating Cognition In A Workspace Virtually, Chiu-Shui Chan Oct 2015

Evaluating Cognition In A Workspace Virtually, Chiu-Shui Chan

Chiu-Shui Chan

In any built environment, there exist certain subtle stimuli that affect the occupants’ cognitive processes and performance. This research intends to identify: (1) what environmental stimuli an office building would generate that could affect the habitants’ cognitive ability, and (2) how the habitants react to these stimuli. The goals of the study are to develop a new method for using immersive virtual reality to represent a built environment for simulating environmental impact, and to discover factors that could influence habitants’ cognitive performance in a space. It is expected that the discoveries could advance the application of virtual reality to study ...

Development Methods And A Scenegraph Animation Api For Cluster Driven Immersive Applications, Brandon J. Newendorp, Christian J. Noon, Chiu-Shui Chan, Eliot H. Winer, James H. Oliver

Mechanical Engineering Conference Presentations, Papers, and Proceedings

This paper presents a scenegraph animation application programming interface (API), known as the Animation Engine, which was constructed for software developers to easily perform smooth transitions and manipulations to scenegraph nodes. A developer can use one line of code to enter the property, end state and number of frames to describe the animation, then the Animation Engine handles the rest in the background. The goal of the Animation Engine is to provide a simple API that integrates into existing applications with minimal effort. Additionally, techniques to improve virtual reality (VR) application performance on a large computer cluster are presented. These ...

How Real Is The Sense Of Presence In A Virtual Environment?: Applying Protocol Analysis For Data Collection, Chiu-Shui Chan, Chien-Hui Weng Jan 2005

How Real Is The Sense Of Presence In A Virtual Environment?: Applying Protocol Analysis For Data Collection, Chiu-Shui Chan, Chien-Hui Weng

Architecture Conference Proceedings and Presentations

This study attempts to investigate the sense of presence in a fully immersive virtual environment. The methodology applied in this study used protocol analysis for data collection. A preliminary experiment was conducted to explore noticeable phenomena to develop a hypothesis for the final experiments. Four different virtual reality models, representing four different kinds of virtual space, were navigated in C6 (CAVE facilities) by two human subjects. Results of the research in this direction have provided valuable understanding regarding the sense of presence in the virtual environment.
