Impact of desktop virtual reality on system usability :
A Case Study of online consumer survey using a VR integrated decision support SYSTEM
Dr. James Laffey, Dissertation Supervisor
Ph.D. Dissertation

ABSTRACT
Previous research has established that virtual reality (VR) technology provides users a unique user-system interaction. However, little research has been conducted to understand how VR technology contributes to system usability within specific contexts. The current research investigates how users perceive desktop VR differently from conventional 2D graphics and how system usability is affected by the user-system interaction process within a VR system. The impact of desktop VR on system usability was empirically examined from an integrated view of technology acceptance in information systems and human-computer interaction. This research tested a model of the user-system interaction process (perceived ease of use, perceived usefulness, and presence) and outcomes measured by system usability dimensions (satisfaction and decision confidence) for a VR system. Data were collected to compare the process and outcomes of using a VR system and a conventional 2D system to engage in a consumer survey. In addition, how user characteristics affect user-system interaction while using a VR system was examined. The results largely support the proposition that VR technology provides system usability with significantly higher perceived usefulness and presence than do the conventional 2D formats. The current work provides new knowledge about usability, sense of presence and technology acceptance in desktop VR and provides insights for future research with and predicted applications of desktop VR.

House X, Scheme G: From 3D Game Engine to Virtual Representations of Architecture
Uddin, M. Saleh and Yoon, So-Yeon (2003), , Journal of Design Communication Association 2003, pp64-69

-suggest to architects the potentials of using universal or exchangeable
formats of 3D models that are capable of representing accurate structure data to build virtual models.
-provide better understanding of potentials in 3D game engines for virtual representation of architecture.

This session will discuss the reconstruction of the historic Apollo Theater as a virtual environment, including: (1) To discuss 3D computer graphic program platform comparisons: Quake III, Macromedia Director, and Adobe Atmosphere, (2) To demonstrate the 3D environment of the Apollo Theater rebuilt in virtual space using Quake III, a 3D game engine, (3) To share some of the lessons we learned, decisions we made and some logistical and technical details about the Quake III modeling process.

M.HEC. THESIS
Interior Design and Housing, Pusan National University

goal
to develop a tool to evaluate color images
to analyze the visual effects of interior colors
using computer generated images
experiment
Subjects : 63 college students
Stimuli: color laser prints of a computer rendered living
room with 24 different color combinations (sofa, wall,floor)
