Retracted] Virtual Reality‐Based Digital Restoration Methods and Applications for Ancient Buildings

At a time of rapid technological development, 3D stereoscopic images and virtual reality technology are being used in art and design, as well as in the digital conservation of ancient buildings and their restoration. Virtual reality art is a high degree of integration between art and digital technology and is a new form of digital art. As a means of presenting architectural art, digital restoration of ancient buildings is a form of expression that combines knowledge, art, and technology. The digital restoration of ancient buildings and the creation of a 3D interactive display system are of great value for the realization of real space and the preservation of ancient sites. In this paper, we design a system that combines 3D stereoscopic and virtual reality technologies for the restoration of ancient buildings. Through the research and practice of this system, it can be translated into relevant design application research in other art and design fields, which is of great practical significance for future virtual reality expansion space.

PEMODELAN HARGA EMAS DUNIA MENGGUNAKAN METODE NONPARAMETRIK POLINOMIAL LOKAL DILENGKAPI GUI R

Investing in gold is a flexible choice because it can be sold at any time and used as an emergency fund. Investors should have the knowledge to predict data from time to time to achieve investment goals. One of the statistical methods for time series data modeling is ARIMA. The ARIMA model is strict with the assumptions that the data must be stationary, the residuals must be normally distributed, independent, and with constant variance, so an alternative model is proposed, namely nonparametric regression model, which has no modeling assumptions requirement. In this study, the daily world gold price data will be modeled using a local polynomial nonparametric model as an alternative because the assumptions in the ARIMA are not fulfilled. The data is divided into 2 parts, namely in sample data from January 2, 2020 to November 30, 2020 to form a model and out sample data from December 1, 2020 to December 31, 2020 used for evauation of model performance based on MAPE values. The chosen best model is the local polynomial model with Gaussian kernel function of degree 5, bandwidth of 373, and local point of 1744 with an MSE value of 482.6420. The local polynomial model out sample data MAPE value is 0.61%, indicating that the model has excellent forecasting capability. In this study, Graphical User Interface (GUI) using R software with the help of shiny package is also built, making data analyzing easier and generating more interactive display output.

IMPLEMENTASI PAKET SHINY PADA PEMODELAN MULTISCALE AUTOREGRESSIVE UNTUK DATA HARGA SAHAM BBRI

Stocks are an investment that attract people because they can earn large profits by having claim rights to the company's income and assets so investors have to observe stock price movements in the future to achieve investment goals. One of the statistical methods for time series data modeling is ARIMA. However, modeling assumptions must be fulfilled to use that method so an alternative model is proposed, namely nonparametric regression model, which has no modeling assumptions requirement. In this study, the nonparametric regression multiscale autoregressive (MAR) with two different filter and decomposition level J are compared to choose the best model and forecast it. The data are closing stock price, high stock price and low stock price of BBRI’s stocks that divided into 2 parts, namely in sample data from March 19, 2020 to February 4, 2021 to form a model and out sample data from February 5, 2021 to March 23, 2021 used for evaluation of model performance based on MAPE values. The chosen best model for each stock price are the MAR model with wavelet haar filter and decomposition level 5 for the closing stock price which produces a MAPE value of 1.194%, the MAR model with wavelet haar filter and decomposition level 5 for the high stock price which produces a MAPE value of 1.283%, and the MAR model with a wavelet haar filter and decomposition level 5 for the low stock price which produces a MAPE value of 1.141%, indicating that the models have excellent forecasting capability. In this study, Graphical User Interface (GUI) using R software with the help of shiny package is also built, making data analyzing easier and generating more interactive display output.

Caffe2Unity: Immersive Visualization and Interpretation of Deep Neural Networks

Deep neural networks (DNNs) dominate many tasks in the computer vision domain, but it is still difficult to understand and interpret the information contained within these networks. To gain better insight into how a network learns and operates, there is a strong need to visualize these complex structures, and this remains an important research direction. In this paper, we address the problem of how the interactive display of DNNs in a virtual reality (VR) setup can be used for general understanding and architectural assessment. We compiled a static library as a plugin for the Caffe framework in the Unity gaming engine. We used routines from this plugin to create and visualize a VR-based AlexNet architecture for an image classification task. Our layered interactive model allows the user to freely navigate back and forth within the network during visual exploration. To make the DNN model even more accessible, the user can select certain connections to understand the activity flow at a particular neuron. Our VR setup also allows users to hide the activation maps/filters or even interactively occlude certain features in an image in real-time. Furthermore, we added an interpretation module and reframed the Shapley values to give a deeper understanding of the different layers. Thus, this novel tool offers more direct access to network structures and results, and its immersive operation is especially instructive for both novices and experts in the field of DNNs.

On the Use of Large Interactive Displays to Support Collaborative Engagement and Visual Exploratory Tasks.

Large interactive displays can provide suitable workspaces for learners to conduct collaborative learning tasks with visual information in co-located settings. In this research, we explored the use of these displays to support collaborative engagement and exploratory tasks with visual representations. Our investigation looked at the effect of four factors (number of virtual workspaces within the display, number of displays, position arrangement of the collaborators, and collaborative modes of interaction) on learners’ knowledge acquisition, engagement level, and task performance. To this end, a user study was conducted with 72 participants divided into 6 groups using an interactive tool developed to support the collaborative exploration of 3D visual structures. The results of this study showed that learners with one shared workspace and one single display can achieve better user performance and engagement levels. In addition, the back-to-back position with learners sharing their view and control of the workspaces was the most favorable. It also led to improved learning outcomes and engagement levels during the collaboration process.

Smart Health Pregnancy by Augmented Reality: An Interactive Guide for Embryo Growth Using Multi-Marker

This research aims to create Smart Health Pregnancy software that educates pregnant women on fetal development. During pregnancy, a pregnant woman’s health highly influences the pregnancy success rate. Thus, knowing the pregnancy process is necessary for pregnant women. Although resources concerning fetal development such as textbooks, general articles, and websites can be accessed easily, these resources are often too condensed with text, have a less interactive display, and provide inadequate information. Therefore, Smart Health Pregnancy software would facilitate pregnant women in understanding fetal development, displayed in an interactive way using Augmented Reality (AR) technology. The AR method utilized is a marker-based tracking method where the user can use an Android smartphone camera to receive a marker that can display a virtual object in the real world. The virtual object is presented in the form of the embryo or fetus from 1 to 38 weeks in 3D. Furthermore, important information regarding fetal development and the health of pregnant women is also shown. From the results, 95% of the respondents stated that this software is user-friendly and very informative. It shows that the software has performed well and can educate pregnant women.

A Novel Touch Interface with Ultrahigh Optical Transmittance Based on Electrical Impedance Tomography for Interactive Displays

AbstractIn traditional touch interfaces, electrodes will block the light intensity of the display, so extra power is required to maintain the display performance. In this article, an eight‐electrode electrical impedance tomography system for touch location detection is proposed to improve the transmittance. The electrodes are settled at the edge of the touch panel and a machine learning algorithm is used to perform the regression process. This system can achieve almost 1 mm mean absolute error in X‐ and Y‐directions on a 30 × 30 mm2 2D surface and guarantee nearly 94% light transmittance. The results from experiments show the feasibility of the new structure for high optical transmittance interactive display in the future.

(Don't) Mind the Step

It is well established that the presence of other people and the physical traces of their activities impact our navigation decisions, e.g. following a path in a park where trails are worn by frequent passage. Here we investigate such effect within a digital setup where social cues are displayed on the floor. We contribute the first lab study (n=24) investigating how social cues, presented as footprints on an interactive floor display, can impact navigation decisions. We particularly explore two task-based scenarios: exploration and search. A direct comparison of path choices did not reveal significant effects in both tasks but a further qualitative analysis showed that social cues affected path choices depending on how participants interpreted them. Additionally, results revealed a pattern of direct decision-making behaviours when social cues were present. We discuss how these insights can contribute to designing engaging floor interfaces that guide navigation decisions using social cues.

Textile-Based Humidity-Driven Wearable Electroluminescent for Visual Sensing

Miniaturization and integration have become a trend of modern wearable intelligent electronics. But how to visualize sensing information in a single-level device remains a challenge. Here, we present a humidity-driven textile-based electroluminescent (EL) interactive display that allows for both sensing and visualization of humidity changes. Based on an interdigitated EL structure, a transparent humidity sensor layer with high humidity sensitivity was creatively introduced on the top-emitting layer as a bridging electrode. The visualization and sensing of humidity can be attributed to the electrical conductivity difference of the sensor layer, thus leading to the varied lighting emitting of EL devices on the application of given electric fields. Benefiting from the highly sensitive sensor layer and well-designed device structure, a variety of humidity-based behavior can be read immediately, including hand-writing and finger approach. Furthermore, our devices fabricated from textiles have great flexibility, breathability, and skin affinity, which is very suitable for human wearing. More importantly, this humidity-driven textile-based EL interactive display shows great application potential in breathing monitoring and health assessment.

Toward adaptive auralization of dynamic immersive virtual environments in room-centered virtual reality systems

Existing auralization frameworks for interactive virtual environments have found applications in simulating acoustic conditions for binaural listening and real-time audiovisual navigation. This work, situated at the Collaborative-Research Augmented Immersive Virtual Environment Laboratory (CRAIVE-Lab), extends elements of these frameworks for human-scale interactive audiovisual display with movement of virtual sound sources and non-static virtual representation of the facility’s footprint. The work involves the development of an adaptive acoustic ray-tracing prototype that is capable of generating impulse responses for individual virtual loudspeaker representation based upon changes of room orientation in virtual space at runtime. Through the integrated use of game engines (i.e., Unity and Unreal Engine), the prototype is presented in the context of dynamic audiovisual display, and actively analyzes the virtual scene geometries using a multi-detailed rendering approach. With both reconstructed high-resolution 3D models of existing spaces, and automatically generated virtual landscapes from geo-spatial data, the developed system is evaluated both in terms of computational efficiency, and in terms of conventional room acoustics parameters using model-based acoustic energy decay analysis across listening region.

Globalizing constraint models

We present a method to detect implicit model patterns (such as global constraints) that might be able to replace parts of a combinatorial problem model that are expressed at a low-level. This can help non-expert users write higher-level models that are easier to reason about and often yield better performance. Our method generates candidate model patterns by analyzing both the structure of the model – its constraints, variables, parameters and loops – and the input data from one or more data files. Each candidate is scored by comparing a sample of its solution space with that of the part of the model it is intended to replace. The top-scoring candidates are presented to the user through an interactive display, which shows how they could be incorporated into the model. The method is implemented for the MiniZinc modeling language and available as part of the MiniZinc distribution.

Development of a yoga posture coaching system using an interactive display based on transfer learning.

Yoga is a form of exercise that is beneficial for health, focusing on physical, mental, and spiritual connections. However, practicing yoga and adopting incorrect postures can cause health problems, such as muscle sprains and pain. In this study, we propose the development of a yoga posture coaching system using an interactive display, based on a transfer learning technique. The 14 different yoga postures were collected from an RGB camera, and eight participants were required to perform each yoga posture 10 times. Data augmentation was applied to oversample and prevent over-fitting of the training datasets. Six transfer learning models (TL-VGG16-DA, TL-VGG19-DA, TL-MobileNet-DA, TL-MobileNetV2-DA, TL-InceptionV3-DA, and TL-DenseNet201-DA) were exploited for classification tasks to select the optimal model for the yoga coaching system, based on evaluation metrics. As a result, the TL-MobileNet-DA model was selected as the optimal model, showing an overall accuracy of 98.43%, sensitivity of 98.30%, specificity of 99.88%, and Matthews correlation coefficient of 0.9831. The study presented a yoga posture coaching system that recognized the yoga posture movement of users, in real time, according to the selected yoga posture guidance and can coach them to avoid incorrect postures.

A stretchable array of high-performance electrochromic devices for displaying skin-attached multi-sensor signals

We report on the fabrication of an interactive display system consisting of a stretchable array of electrochromic devices (ECDs) and temperature and strain sensors for visual display of skin temperature and wrist movement. The electrochromic device is prepared by coating poly(3-hexylthiophene) and tungsten trioxide as electrochromic materials on a flexible and transparent electrode of indium-tin-oxide-coated polyethylene terephthalate, and the subsequent assembly of the prepared electrodes using a gel-type electrolyte of Li-mixed 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide/poly(methyl methacrylate). The fabricated ECD exhibits three different colors due to the redox reactions of the electrochromic materials at the corresponding potentials: magenta, violet, and blue at −1.5 V, 0.5 V, and 1.5 V, respectively. By using patterned liquid metal Galinstan interconnections, a stretchable array of the ECDs is fabricated based on a strain relieving mechanism with an island-bridge design, resulting in mechanical stability to repeated stretching of up to 30%. A high-performance strain sensor is fabricated by embedding fragmentized graphene foams inside poly(demithylsiloxane) thin film, and a temperature sensor is prepared by embedding multi-walled carbon nanotubes/polyaniline composite in poly(vinyl alcohol) film. With the integrated system, the strain due to wrist bending and the skin temperature measured by the sensors are displayed as changes in the color pattern of the ECD array aided by an Arduino circuit. This work demonstrates the high potential of our system for application to wearable healthcare devices providing real-time visual display of varied bio-signals.
