    With the advancement of contemporary technology, there is an increasing demand for sophisticated tone libraries in intelligent and digital pianos. This paper introduces a virtual piano system based on timbre simulation. Drawing upon the articulation principles of the piano, a mathematical model is formulated to derive the equation governing string vibrations. This equation facilitates a comprehensive analysis of the components constituting piano timbre and establishes a model for synthesizing these timbres using a frequency envelope algorithm. The short-time Fourier transform (STFT) is utilized to extract features from the synthesized timbre and to accomplish its digital simulation. Subsequently, the integration of the piano's timbre features with computer programming facilitates the comprehensive design of the virtual piano system. Performance testing and evaluation of the system reveal promising results: the detection rate for each musical piece exceeds 90%, with an average detection rate of 94.81% across ten pieces and an average deviation (Mean-D) of 3.35 in the scoring of 100 music samples. This research contributes to the flexibility in timbre editing, enhances the expressiveness of intelligent and digital pianos, and aims to elevate the music industry to new heights.

    In this paper, in order to solve the modal aliasing problem of the EMD decomposition algorithm and EEMD decomposition algorithm and optimize the vocal audio data decomposition on the basis of the adaptive VMD algorithm, the EEMD-VMD second-order data decomposition algorithm is proposed to decompose the digitized time series of vocal music resources, and to update the construction of the digital library of vocal music resources. Combined with the decomposition steps of the second-order data decomposition algorithm in the vocal resources digitized library, the overall framework of the vocal resources digitized library is designed and constructed with the main line of vocal resource types and the secondary line of content categories. Design the experimental environment, preprocess the vocal audio signal features, explore the modal number K value size of the EEMD-VMD second-order data decomposition algorithm, analyze the vocal audio denoising performance of the algorithm, and compare the correlation coefficients of the IMF components of the decomposition algorithms with the original audio signals. Explore the second-order data decomposition algorithm's emotional classification of vocal resources and the performance of vocal signal enhancement, add noise sources, and use subjective and objective evaluation methods to assess the quality of vocal PESQ and STOI after decomposition processing. The EEMD-VMD second-order data decomposition algorithm performs the most prominently in street noise environments. The enhancement results in the case of signal-to-noise ratios of -5, -10, and -15 are 3.59, respectively, 4.36, 4.29, and the mean value of the enhancement performance reaches 4.08. The second-order data decomposition algorithm's precise processing of vocal resources provides better quality digital resources for the construction of a digital library of vocal resources.

    During the Covid-19 pandemic, e-learning and online learning systems and platforms have become increasingly popular and essential. Currently, numerous e-learning materials covering various subjects have been developed and are widely utilized in practical education. Music instruction education has also confronted this challenge. In this paper, we introduce a piano learning system. We incorporate multi-directional video technology to enable users to observe piano players from their desired angles. Additionally, we integrate MediaPipe into this system to implement hand landmark detection, facilitating users in virtual piano playing. We also use an experiment to evaluate the educational efforts of our system.

    This paper treats the user study for web-based VR education contents supporting VR-goggles. Educational materials using multimedia have ability to enhance the education efficiency rather than text books. Similarly, educational materials using new technologies like VR have ability to attract much interests of students. Based on Interest-Driven Creator Theory (IDC Theory), this means educational materials using VR may have high educational efficiency. For experiment subjects and exercise subjects, the most efficient learning environments should be the same as the real ones as possible. Educational materials using VR can provide virtually students with high immersive learning environments. Therefore, educational VR materials supporting VR-goggles may have higher education efficiency rather than the others. This may justify Seamless Interest-Driven Creator Theory (SIDC Theory). So, this paper introduces several web-based VR education contents, and also show simple user study results especially for the comparison between their web-browser mode and VR goggle mode.

    This paper proposes new development framework based on OpenVSLAM for web-based VR tours using 360VR videos. Although the authors have already proposed the development framework for web-based VR tours as navigation contents of 360VR videos and as walkthrough contents of 360VR images, it is not easy to prepare 360VR images because the authors took over 300 360VR images at different locations for the walkthrough contents of 360VR images introduced in this paper. Therefore, in this paper, the authors propose new development framework for web-based VR tours as both navigation contents and walkthrough contents from 360VR videos. For walkthrough contents of 360VR images, 360VR videos of navigation contents can be used instead of 360VR images because required 360VR images can be extracted from 360VR videos of the same scene. In this case, only 360VR videos of a portable 360VR camera like Insta360 ONE X2 are enough. The development framework for navigation VR tours of 360VR videos need their moving path information and for walkthrough VR tours of 360VR images need their location information. The authors have created them manually so far. For generating them automatically, the authors decided to employ OpenVSLAM. This paper shows evaluation results how accurate moving paths and location information can be generated by OpenVSLAM.

    This paper treats a development framework for web-based VR tours of 360VR camera images/videos and lidar scanner data and introduce several example VR tours actually developed using the framework. Because of the advancement of XR(VR/AR/MR) technologies such as lidar scanners, 360VR cameras and high specification VR goggles, the demand of XR applications has become increased. However, the development of such XR applications is tedious work that needs much time. Therefore, the authors have proposed the development framework for web-based VR tours of 360VR camera images/videos and lidar scanner data and this paper introduces it and several VR tours as its examples.

    Recently, VR goggles like Oculus Quest 2 have become popularized because such goggles are more portable and cheaper than ever. As a result, Metaverse to be realized using such goggles will become popular as one of the immersive network collaborative environments. So, in this paper, the authors propose the design and implementation for that. For multiple persons’ network collaborations, the functionality to capture their actions simultaneously is required. So, the authors propose the use of OpenPose with 360VR camera in their design because OpenPose generates multiple persons’ pose information from a video almost in real-time and 360VR camera generates a video that covers a wide area including multiple persons. On the other hand, such immersive network collaborative environments are very complicated and their development is not easy. So, the authors also propose the use of WebXR of Three.js in their design because Three.js is one of the popular 3D graphics libraries for web contents and it provides functionality required for WebXR that supports VR goggles. For justifying the proposed design, the authors implemented a prototype system of an immersive network collaborative environment. This paper explains the proposed design and the details of the prototype system.

  • Web Viewer for Educational VR Contents of 3D Scene Models Supporting VR Goggles

    Okada Y., Kaneko K., Shi W.

    Lecture Notes on Data Engineering and Communications Technologies  2024年    ISSN:23674512

     詳細を見る

    In this paper, the authors introduce web viewers for educational VR contents. Especially, they propose new web viewer for educational VR contents of 3D scene models. Although there have been many types of VR goggles and a lot of entertainment VR contents, there have been a few educational VR contents. To enhance educational efficiency using VR technology, such educational VR contents should be created more and more. On the other hand, many types of scanning devices have been researched and developed, e.g., Lidar scanners, 360VR cameras and so on. Using these scanning devices, 3D data like Point Cloud Data (PCD), 3D model data and 360VR images/videos, can be obtained easily. To use these 3D data for educational VR contents, the authors have already developed viewer applications as web services. These web viewers have functionality to upload 3D data from users' web-browser to the web-server on that the web viewers work. However, 3D scene models are not supported. Standard videos are still important media for the on-demand online educations. Therefore, the authors propose new web viewer for 3D scene models supporting standard videos and VR goggles in this paper.

  • OpenVSLAM-Based Development Framework for Web-Based VR Tours Using 360VR Videos and Its Extensions

    This paper proposes an extended development framework for web-based VR tours using 360VR videos based on OpenVSLAM. The authors have already proposed the development framework for web-based VR tours as navigation contents of 360VR videos and as walkthrough contents of 360VR images. However, it is not easy to prepare 360VR images of different locations for the walkthrough contents if the number of those images is too many. So, the authors have also proposed new development framework for web-based VR tours as both navigation contents and walkthrough contents using 360VR videos, not using 360VR images. For the walkthrough contents, we use 360VR videos because the required 360VR images can be extracted as keyframes of the same scenes from the 360VR videos. Furthermore, when there are many scenes, i.e. many 360VR images in one VR tour, it will become very convenient that the user can go to his/her desired scenes directly by the keyword search. Also, when 360VR videos created as educational contents include audio narrations, it will become also very convenient if the multi-language subtitles are available from the audio narrations. So, the authors extended their development framework for web-based 360VR tours to support the keyword search and multi-language subtitles using Google Cloud Vision AI and free AssemblyAI services.

    This paper proposes a web-based radiation visualization tool for radiation protection learning. During the radiation therapy, a medical doctor and his/her assistants besides a patient are faced with the radiation exposure. To protect the radiation exposure, medial students have to learn the protection methods against the radiation exposure. Several simulation codes have already been developed for understanding the radiation dose distribution. There is a research to visualize the simulation results using ParaView tool. Although its educational efficiency was confirmed, too many functions of ParaView require users much time to learn its operations, and preparations such as installation of ParaView are also burdensome for users. Therefore, the authors developed and evaluated a web-based interactive radiation visualization tool that allows users to prepare the learning environment simply and interactively reflecting the effects of protective equipment in addition to visualizing radiation dose distribution.

    This paper proposes a development framework using 360VR cameras and lidar scanners for web-based XR educational materials that supports VR goggles. Recently, the demand of XR (VR/AR/MR) applications has become increased due to the advancement of XR technologies, e.g., high specification VR goggles, 360VR cameras and lidar scanners have become available at a cheaper price rather than ever. Although more than ten years ago, many entertainment XR applications have been produced, XR applications in other fields have not been so. Besides the entertainment field, educational materials using XR have become in great demand. Especially, XR seems useful for educational materials of experiment and exercise subjects. However, the development of such educational materials is not easy and needs much time. Therefore, in this paper, the authors propose the development framework for them. In this paper, the authors also show several material examples to justify the usefulness of the proposed framework.

    Avoiding obstacles and pedestrians during the movement is a challenge for the visual impaired people. With the advancement of computer vision, some new technologies can be applied to improve this problem. In this paper, we proposed a new framework to realize such function based on the object tracking algorithm, FairMOT. Our framework detects the pedestrians around users and alarm users to avoid the collision between them. In our system, we use the 360-degree camera as the system input to record the users’ surrounding situations, and use the VR headset as the output device with a feedback application, that is realized using WebVR technologies. In this paper, we also discuss some experiments of the current system and some further improvement methods according to the results of experiments.
