This study aims to identify the suitable model for building virtual museum and the essential elements for managing technology based product. Since the majority of these models derive from immersive virtual reality, a new architecture was formed with the basic elements involved in that environment. It has found that 3D models are a good attraction where user can experience the virtual as if it was reality. Lighting was used to brighten up the environment and the many interesting objects. Camera is used as an 'eye' view where users can freely walk through the environment from the camera view. collision detection was added in camera setting to ensure the collision in that environment truly occurs when user hits the project. While video are used to replace display screen in immersive environment, texture mapping are used to imitate reality surface objects. In addition, this study has discovered some design issues during development activity. This whole has adapted the Systems Development Research methodology. The key step includes the design and development of the Virtual Museum prototype itself. At the phase, besides management techniques of camera, lights and texture elements, the researcher also has succeeded in managing the walk through technique with collision detection and putting videos in VR. File management enable the researcher to access sources much easier. Indirectly, the development of this prototype has overcome these problems and answered the first research question all at one time. The outcome of this prototype was successfully developed using right development management techniques. Henceforth, this study also aims to test the usability of this system to users in using Technology Acceptance Model. Perceived usefulness, perceived ease of use and perceived enjoyment are the independent variables in testing intention to use by visitor. Theoretical framework was produced and hypotheses were developed and tested using Spearmen Correlation Matrix and Regression Analysis. It has found that all hypotheses were supported, where the most influent factor is Perceived Usefulness followed by Perceived Enjoyment and Ease of Use. The output of this research is the Virtual Museum prototype of Kedah State Museum, provided with interactivity and ability to represent the real physical environment digitally. Hopefully this research can be a guideline to virtual museum developers to develop video application and three dimension walk through system construction.
