“…Nevertheless, the presence of a point cloud out of the context of the virtual environment can still reduce the sense of presence for users. Other visualizations such as occupancy maps and glass walls can also negatively affect the feeling of presence [31], [32]. In addition, there are similar methods that incorporate visual indicators such as wireframes into the virtual environment to show real-world obstacles [7], [8].…”

“…To preserve a high level of presence in the virtual scene, the objects used to construct the virtual scene should match the theme of the scene, and the objects should have coherent placements in line with human intuition. For example, when the user is in a kitchen, if there is a bathtub or a little hill next to the stove, these objects are out of the context of the scene and will spoil the user's sense of presence [31], [32]. Therefore, we extract associations between objects and layout patterns from the virtual scene dataset to guide our system to generate a reasonable virtual scene.…”

In this paper, we propose a system that can automatically generate immersive and interactive virtual reality (VR) scenes by taking real-world geometric constraints into account. Our system can not only help users avoid real-world obstacles in virtual reality experiences, but also provide context-consistent contents to preserve their sense of presence. To do so, our system first identifies the positions and bounding boxes of scene objects as well as a set of interactive planes from 3D scans. Then context-consistent virtual objects that have similar geometric properties to the real ones can be automatically selected and placed into the virtual scene, based on learned object association relations and layout patterns from large amounts of indoor scene configurations. We regard virtual object replacement as a combinatorial optimization problem, considering both geometric and contextual consistency constraints. Quantitative and qualitative results show that our system can generate plausible interactive virtual scenes that highly resemble real environments, and have the ability to keep the sense of presence for users in their VR experiences.

“…For example, Oasis [8] utilizes a mechanism for creating a VR space and enabling real walking that uses a pre-scanned real environment. As a mechanism for expanding the play area, Keller et al proposed a system that enables real walking by dynamically acquiring the environment around the user and integrating it with the virtual space [9]. In these examples, a VR space is created in advance, in order to enable real walking.…”

“…This means that restoration is impossible, even if the inverse STFT and STFT are performed. Therefore, in this iterative method, the phase is obtained with the constraint that the correct STFT expression is obtained while fixing the amplitude to A(m, k) from Equation (9). In this way, the generated image is converted into sound data, and the result is presented to the user.…”

Impact Sound Generation for Audiovisual Interaction with Real-World Movable Objects in Building-Scale Virtual Reality

In building-scale VR, where the entire interior of a large-scale building is a virtual space that users can walk around in, it is very important to handle movable objects that actually exist in the real world and not in the virtual space. We propose a mechanism to dynamically detect such objects (that are not embedded in the virtual space) in advance, and then generate a sound when one is hit with a virtual stick. Moreover, in a large indoor virtual environment, there may be multiple users at the same time, and their presence may be perceived by hearing, as well as by sight, e.g., by hearing sounds such as footsteps. We, therefore, use a GAN deep learning generation system to generate the impact sound from any object. First, in order to visually display a real-world object in virtual space, its 3D data is generated using an RGB-D camera and saved, along with its position information. At the same time, we take the image of the object and break it down into parts, estimate its material, generate the sound, and associate the sound with that part. When a VR user hits the object virtually (e.g., hits it with a virtual stick), a sound is generated. We demonstrate that users can judge the material from the sound, thus confirming the effectiveness of the proposed method.
