Synchronised neural signature of creative mental imagery in reality and augmented reality

Creativity, transforming imaginative thinking into reality, is a mental imagery simulation in essence. It can be incorporeal, concerns sophisticated and/or substantial thinking, and involves objects. In the present study, a mental imagery task consisting of creating a scene using familiar (FA) or abstract (AB) physical or virtual objects in real (RMI) and augmented reality (VMI) environments, and an execution task involving effectively creating a scene in augmented reality (VE), were utilised. The beta and gamma neural oscillations of healthy participants were recorded via a 32 channel wireless 10/20 international EGG system. In real and augmented environments and for both the mental imagery and execution tasks, the participants displayed a similar cortico-cortical neural signature essentially based on synchronous vs asynchronous beta and gamma oscillatory activities between anterior (i.e. frontal) and posterior (i.e. parietal, occipito-parietal and occipito-temporal) areas bilaterally. The findings revealed a transient synchronised neural architecture that appears to be consistent with the hypothesis according to which, creativity, because of its inherent complexity, cannot be confined to a single brain area but engages various interconnected networks.

USE OF TOOLS AND SERVICES OF CLOUD-BASED SYSTEMS IN TEACHERS’ TRAINING AND PROFESSIONAL DEVELOPMENT: ASPECT OF AUGMENTED REALITY

The article reveals the aspect of using augmented reality (AR) as a means of a cloud-based open education and science system. Research methods: analysis, generalization, systematization of scientific-methodical sources on the research problem, analysis of cloud-based tools and services, determination of theoretical bases of teacher professional development on using cloud-oriented systems of open education and science. In the context of open science, the interest of scientists in the use of ICT during the period of the large-scale COVID-19 pandemic was analyzed and it was found that the number of publications in the areas of use of information and communication technologies, the introduction of distance learning, the development of information and communication and STEM competence has increased rapidly. The survey of lyceums teachers resulted that teachers chose three simple means for organizing distance learning, as well as the direct dependence in the choice of these means – digital analogs of full-time education (Zoom – lesson, Viber – diary, website – school announcements). The author considered the issue of the lack of high-quality digital content and the use of AR-objects, implemented using the MERGE Cube technology, in pedagogical practice. The cloud-based system of using MERGE Cube for learning is described, the stages of using MERGE Cube in the educational process, the criteria for the quality of AR-content (correspondence of virtual additions to the content of the lesson or the topic being studied; sound effects emphasize artistic or other meaning; video fragments demonstrate processes, events or video instructions by content; the process of playing AR objects is simple, intuitive; the process of playing AR is technically stable; the text font is dynamic; 3D images are clear; AR objects are reproduced in various operating systems). The author draws attention to the need to develop instructions and digital maps for the lesson. It was found that the key factor in the spread of AR technology in education is open access to educational content and the development of teachers’ relevant competencies.

Intuitive Manipulation of Virtual Clay in Augmented Reality

In recent years, there has been a lot of research on how to achieve interaction between users and virtual objects using augmented reality. Interaction technologies in augmented reality need to enable users to handle virtual objects intuitively. In addition, since hands are the main means of interaction with objects in real life, it is also necessary to enable interaction operations with hands on virtual objects [1]. In order to make it possible to intuitively handle objects in virtual space using hands in real space, it is necessary to consider whether physical phenomena in real space and virtual space are correctly superimposed (physical consistency). In this study, we proposed a system that allows users to intuitively handle the deformation, movement, and merging of virtual objects in augmented reality. The system was then used by four university students to compare it with existing studies [2].

The Use of Location-Based Augmented Reality as Information Media in The Digital Map Application of Jakabaring Sport City

Jakabaring Sport City (JSC) is an integrated sports facility complex and a public tourist spot in Palembang. Due to its extensive area and numerous facilities, visitors need a map with distinct markers for the landmark to make it easier when walking around. Recent technology advancements and its expanding role in various fields invites the question on how to integrate technology in the tourism industry. This journal aims to create an android-based digital map application with augmented reality (AR) as a guiding medium that will display directions towards the Jakabaring exit gate. This app is built using Maps SDK for Android to build the digital maps, Navigation SDK for Android to run navigation, and Maps for Unity to display AR objects that will show the directions towards the exit. The development focuses on a location-based service using GPS to track the user's whereabouts and provide real-time location data around the user. This application has a location search feature, a guiding direction (route and navigation) to a designed location, and an AR camera feature to display where the JSC exit gate is located. Every feature is working well and able to help users while visiting JSC. However, this application could still be improved in the AR feature because on its current version, it is only able to display directions to the JSC exit gate when users are within a radius of one kilometer or less to the exit.

Wearable Haptic Device for Stiffness Rendering of Virtual Objects in Augmented Reality

We propose a novel wearable haptic device that can provide kinesthetic haptic feedback for stiffness rendering of virtual objects in augmented reality (AR). Rendering stiffness of objects using haptic feedback is crucial for realistic finger-based object manipulation, yet challenging particularly in AR due to the co-presence of a real hand, haptic device, and rendered AR objects in the scenes. By adopting passive actuation with a tendon-based transmission mechanism, the proposed haptic device can generate kinesthetic feedback strong enough for immersive manipulation and prevention of inter-penetration in a small-form-factor, while maximizing the wearability and minimizing the occlusion in AR usage. A selective locking module is adopted in the device to allow for the rendering of the elasticity of objects. We perform an experimental study of two-finger grasping to verify the efficacy of the proposed haptic device for finger-based manipulation in AR. We also quantitatively compare/articulate the effects of different types of feedbacks across haptic and visual sense (i.e., kinesthetic haptic feedback, vibrotactile haptic feedback, and visuo-haptic feedback) for stiffness rendering of virtual objects in AR for the first time.

Designing A 3-Dimensional Campus Brochure Application Based On Augmented Reality

STMIK Umel Mandiri as one of the universities in Jayapura is still less well known, apart from being relatively new in its age and the location of the campus building which is blocked by buildings. So that people sometimes do not know the exact location of the campus. To promote the campus, one of the advertising media used is brochures. Along with current technological developments, augmented reality technology has emerged which is able to combine 2 (two) realities, namely the real and virtual world. When used in brochures, it can provide a feel and experience for readers. So that promoting goods or services can be done more interactively, as well as providing more information to consumers about the product. This augmented reality technology is then used as a solution to the problems faced by STMIK Umel Mandiri in promoting its educational institutions. The purpose of this research is to produce an android application that can display a 3 (three) dimensional brochure model by utilizing augmented reality technology so that it can help the public to get to know the campus to be chosen well. The research method has several stages, namely collecting data about the needs of prospective new students regarding information about the STMIK Umel Mandiri campus, then making a 3 (three) dimensional model of the STMIK Umel Mandiri Campus Building. Then next, do the design of compatible augmented reality on smartphone devices using the Android operating system, and produce 3 (three) dimensional augmented reality objects. This research produces an application based on augmented reality technology that is used to help promote the STMIK Umel Mandiri Campus through devices with the android operating system.

Using visual and auditory cues to locate out-of-view objects in head-mounted augmented reality

When looking for an object in a complex visual scene, Augmented Reality (AR) can assist search with visual cues persistently pointing in the target’s direction. The effectiveness of these visual cues can be reduced if they are placed at a different visual depth plane to the target they are indicating. To overcome this visual-depth problem, we test the effectiveness of adding simultaneous spatialized auditory cues that are fixed at the target’s location. In an experiment we manipulated which cue(s) were available (visual-only vs. visual + auditory), and which disparity plane relative to the target the visual cue was displayed on. Results show that participants were slower at finding targets when the visual cue was placed on a different disparity plane to the target. However, this slowdown in search performance could be substantially reduced with auditory cueing. These results demonstrate the importance of AR cross-modal cueing under conditions of visual uncertainty and show that designers should consider augmenting visual cues with auditory ones.

Base64 Color Code

QR code widely used as an url to link to a website or data that contains the essential text to fetch. Its nearly a decade has been used in day today life on products. An idea about re-inventing the qr code in such a way that making files in transformation of base64 (code text)which then formatted to a pattern of qr code which enables qr code has the content of the file. Now when a person scans the QR(Quick Response) code without the interaction with the internet he gets the app or the file in his device. While in this if the scanner of the app has the predefined AR(Augmented reality) object which helps the today's world to make an advertisable mode for attracting customers. Like adding a predefined cube with rotating animation. Now the user just has to add text on what side has to be placed. so image code just has to contain the text on which side and what speed the cube to rotate. By this a new way already defined library holding in decoder or scanner app helps the user interaction and content delivery easily. In this adding color QR code which gives the possibility to explore more data into it .

Estimating Distances in Action Space in Augmented Reality

Augmented reality ( AR ) is important for training complex tasks, such as navigation, assembly, and medical procedures. The effectiveness of such training may depend on accurate spatial localization of AR objects in the environment. This article presents two experiments that test egocentric distance perception in augmented reality within and at the boundaries of action space (up to 35 m) in comparison with distance perception in a matched real-world ( RW ) environment. Using the Microsoft HoloLens, in Experiment 1, participants in two different RW settings judged egocentric distances (ranging from 10 to 35 m) to an AR avatar or a real person using a visual matching measure. Distances to augmented targets were underestimated compared to real targets in the two indoor, RW contexts. Experiment 2 aimed to generalize the results to an absolute distance measure using verbal reports in one of the indoor environments. Similar to Experiment 1, distances to augmented targets were underestimated compared to real targets. We discuss these findings with respect to the importance of methodologies that directly compare performance in real and mediated environments, as well as the inherent differences present in mediated environments that are “matched” to the real world.

Effects of Augmented Reality Object and Texture Presentation on Walking Behavior

Wearable devices that display visual augmented reality (AR) are now on the market, and we are becoming able to see AR displays on a daily basis. By being able to use AR displays in everyday environments, we can benefit from the ability to display AR objects in places where it has been difficult to place signs, to change the content of the display according to the user or time of day, and to display video. However, there has not been sufficient research on AR displays’ effect on users in everyday environments. In this study, we investigate how users are affected by AR displays. In this paper, we report our research results on the AR displays’ effect on the user’s walking behavior. We conducted two types of experiments—one on the effects of displaying AR objects on the user’s walking path, and the other on the effects of changing the floor texture by AR on the user’s walking behavior. As a result of the experiments, we found that the AR objects/textures affected the user’s walking behavior.

Specifics of using image visualization within education of the upcoming chemistry teachers with augmented reality technology

It is beneficial to study chemical disciplines, applying the Augmented Reality for the upcoming chemistry teachers, as far as the visualisation of the demonstration material in the 3D helps students understand various processes and phenomena, the structure of chemical compounds and the mechanisms of their correlation in a better way. The object of the project is the development of program and printed tools, designed to visualize the education process within chemistry disciplines according to the augmented reality technology. The authors have developed applications, designed for visualisation of the study material with AR. When a mobile phone is pointed on a marker, the image “comes to life”, its three-dimensional model appears; it can be manipulated in some way (inversion, enlargement, viewing from different sides) to understand its structure, operating principle etc. better. Applying augmented reality objects gives the teacher an opportunity to explain big amount of theory quickly and effectively, and the students – to memorise it effectively, develops creativity and boosts motivation for study. Applying AR while training the upcoming chemistry teachers gives the ability to prepare them for applying this technology during the education process in the general secondary education establishments.

Using the Visuo-Haptic Illusion to Perceive and Manipulate Different Virtual Objects in Augmented Reality

The prop-based 3D virtual object manipulation method is widely used for interaction in Augmented Reality (AR) due to its convenience and flexibility. However, when the represented virtual object is different from the physical prop, the look and feel of the object are not well aligned. To address this problem, we present a dynamic finger remapping approach to creating a visuo-haptic illusion that dynamically adjusts the presented virtual hand posture to fit different sizes and shapes of virtual objects in AR. The finger movement toward a physical prop is synchronously remapped to the movement of the virtual fingers towards the corresponding virtual object. We developed a system that enables users to perceive consistent visual and tactile feedback while grasping and releasing various virtual objects represented by a physical prop. We conducted a user study to explore the effect of this visuo-haptic illusion on the perceived size of virtual objects, setting the sizes of the rendered virtual object and the physical prop as independent variables. We found that the perceived size of a virtual object varied with its rendered size in an almost linear fashion, while the physical prop size did not significantly affect the perception. We also conducted a second study to compare our system with a current prop-based method on virtual object manipulation. The results indicated that the remapped hands could effectively improve the realism and naturalness of the experience.

Application of Monocular Direct Vision Odometry in Augmented Reality

In recent years, the unlabeled augmented reality system has been gradually applied to various mobile devices, among which stable, accurate, and fast registration is the key to realizing this function. For this technique, this paper introduces camera exposure parameters and puts the data association and pose estimation into a unified nonlinear optimization problem. Moreover, the direct monocular vision odometer is transplanted into the augmented reality system through the position adjustment module. We compare it with the traditional visual odometry method that matches the feature points. The results show that this improved method can be used to track more quickly and build a more visual semi-dense point cloud map, which can be used to support the registration and tracking of virtual objects in augmented reality.

Outdoor Navigation System by AR

Mobile map applications such as Google Maps often don’t provide detailed information about facility areas such as amusement parks and university campuses. In addition, there are some people who cannot reach their destination just by reading a flat map. Therefore, in this research, we have developed an AR (Augmented Reality) navigation application for facilities to solve these problems. In addition, by using Kalman filtering to estimate user position, we could improve the accuracy of AR objects display.

Interaction of models with real objects as a way to improve augmented reality

Unlike a purely virtual world, it is much more difficult for the user to believe in the reality of augmented reality objects. Due to the lack of proper lighting or shadows, the object may appear to be floating in the air, detached from the real objects around it. One obvious problem with augmented reality is that a virtual object appears remote from the real object, but it still appears in front of it. An approach is proposed that will allow the interaction of real and virtual objects. Both real and virtual objects can be moved and rotated in the scene, preserving overlaps. A virtual object can also be placed in front of or behind a real object relative to the camera, which decides whether or not to overlap. The proposed algorithm consists of five stages and the system architecture. The evaluation is based on five defined criteria. Results and ways of improvement for the future research are presented.
