A View Direction-Driven Approach for Automatic Room Mapping in Mixed Reality

Virtual Reality and Augmented Reality technologies have greatly improved recently, and developers are trying to make the experience as realistic as possible and close the gap between the physical world and the virtual world. In this paper, we propose an efficient and intuitive method to create an immersive Mixed Reality environment by automatically mapping your room. Our method is view direction driven, which allows the users to simply “look at” any indoor space to create a 3-dimensional model of the area the user is located in. This approach is easier and more intuitive for the users to use and reduces the time and effort compared to other MR environment generating methods. We use the Meta Quest 2’s cameras and gyroscope sensor and the Unity engine for the ray casting and the passthrough API. We will present the mathematical details of our method and show that the proposed method achieves better results than previous methods through the user study results.
