    Abstract

    Virtual reality (VR) is a technologically created, immersive and interactive space. Interior design is an important profession where creative and technical solutions are applied to achieve a built environment. VR could be very beneficial in that area, but unfortunately most current solutions are just for viewing purposes. The main research question in this thesis is to find out how to create a simple immersive VR interior design system using a collaborative model? The problem is approached via constructive research method; a thorough literature survey along with the design, implementation and evaluation of a new immersive design system called VIDS. Creating VIDS requires studying both navigation and design elements. Three experiments with 16 users are conducted to evaluate different users’ navigation abilities with different tools. For designer user interface, VIDS uses collaborative design model with Wizard of Oz –type collaborative input. The user moves around the model inside the virtual room and makes design requests to the wizard, who is outside on a nearby computer and handles the actual model update. To determine how well immersive interior design can be performed using VIDS, 24 test subjects participate in a kitchen furnishing experiment. The experiment results show that VIDS and collaborative design approach seem to be very effective. The most important strengths are that it allows free movement, real-size view of the space and fast editing. It also promotes better space utilization, encourages practical collaboration and ensures that the working environment is always under total control. Weaknesses include the export/import delay caused by the chosen synchronization solution and the catalogue system that should be improved. Attributes of a practical immersive VR interior design system can be summarized. The system a) should provide the user with a realistic first-person perspective of the environment, b) should be embedded with an ergonomic, quick and practical way to move, c) should include some possibility to collaborate (e.g., simple tasks for user, complicated for the wizard), d) possible pre-defined catalogue should preferably be merged into the software and e) all design modifications should be visible to the user as soon as possible.
