Interior Design in Augmented Reality Environment

Unit33,Interior Design in Augmented Reality Environment,Text,This article presents an application of Augmented Reality technology for interior design. Plus, an Educational Interior Design Project is reviewed. Along with the dramatic progress of digital technology, virtual information techniques are also required for architectural projects. Thus, the new technology of Augmented Reality offers many advantages for digital architectural design and construction fields. AR is also being considered as a new design approach for interior design. In an AR environment, the virtual furniture can be displayed and modified in real-time on the screen, allowing the user to have an interactive experience with the virtual furniture in a real-world environment. Here, AR environment is exploited as the new working environment for architects in architectural design works, and then they can do their work conveniently as such collaborative discussion through AR environment. Finally, this study proposes a new method for applying AR technology to interior design work, where a user can view virtual furniture and communicate with 3D virtual furniture data using a dynamic and flexible user interface. Plus, all the properties of the virtual furniture can be adjusted using occlusion- based interaction method for a Tangible Augmented Reality.,Text,1. INTRODUCTION Visualizing how a particular table or chair will look in a room before it is decorated is a difficult challenge for anyone. Hence, Augmented Reality (AR) technology has been proposed for interior design applications by few previous authors, for example, Koller, C. Wooward, A. Petrovski; K. Hirokazu, et al. The related devices typically include data glasses connected to a portable PC (Head-mounted display- HMD). Plus, various lightweight solutions using a PDA device has been proposed by the Augmented Reality Team in Find land. However, these devices are right not commonly available for non-professional users. Accordingly, this paper presents an augmented reality system for designing、educating、presenting interior design projects using overlaid virtual furniture in a physical environment based on a regular PC home system. Tracking markers are placed on the floors or walls to define the scale and coordinate system of the room. Next, the user selects virtual furniture on the screen and places it in the design space. In the AR scene, the 3D virtual furniture is integrated into a real environment and can be arranged along side real furniture.Experiments are implemented using basic home computer equipment, including a PC, HMD (or web camera), and printer.As a result, it is hoped that the propo-,Text,-sed system will allow a broad range of users. While some similar systems have already been presented by another research group, the system proposed in this paper includes additional functions for the user interface and an improved implementation. For example, the user can interact with virtual furniture using a Tangible Augmented Reality in real time, and change the color, style, or covering of furniture in a real environment. Therefore, this allows complex and varied designs to be explored and visualized, making AR technology for interior design accessible to both professionals and amateurs. 2. AUGMENTED REALITY- NEWRESEARCH APPROACH FOR ARCHITECTURE Augmented Reality technology Augmented Reality (AR) is a new technology that involves the overlay of computer graphics on the real world. As a result, the user can see the real world augmented with virtual objects and can interact with them. Within a more general context, AR is also termed Mixed Reality (MR), referring to a multi-axis spectrum of areas that cover Virtual Reality (VR), Augmented Reality (AR), telepresence, and other related technology (Figure 1).,Figure 1Paul Milgrams Reality- Virtual continuum.,Text,Augmented Reality systems combine digital information and the real world in a way that the user experiences them as one. A particularly important property of AR is locating virtual objects in the right place and position, which makes the Tracking System one of the most important components of an AR system. Essentially, an AR system must be able to follow the users point of view dynamically and keep virtual objects aligned with real world objects. The basic components of an AR system are a display, camera for graphic captures, and computer installed application software, plus various different kinds of hardware can be used, for example, camera phones, PDAs, lap-tops, HMDs, and wearable computer systems. Typically, an ARToolKit library is used to determine the relation between the real and virtual world. The ARToolKit uses a computer vision technique to define the position and orientation of the real camera viewpoint relative to a real world marker. Next, the ARToolKit defines and calculates the position of the virtual coordinates. Based on a concurrence of virtual and real camera coordinates, the computer graphics are then drawn as
