Design and Development of Collaborative AR System for Anatomy Training

Background: Augmented Reality (AR) incorporates both real and virtual objects in real-time environments and allows single and multi-users to interact with 3D models. It is often tricky to adopt multi-users in the same environment because of the devices’ latency and model position accuracy in displaying the models simultaneously. Method: To address this concern, we present a multi-user sharing technique in the AR of the human anatomy that increases learning with high quality, high stability, and low latency in multiple devices. Besides, the multi-user interactive display (HoloLens) merges with the human body anatomy application (AnatomyNow) to teach and train students, academic staff, and hospital faculty in the human body anatomy. We also introduce a pin system to share the same knowledge between multiple users. A total of 5 groups have been considered for the study and the evaluation has been performed using two parameters: latency between the devices and position accuracy of the 3D objects in the same environment. Results: The proposed multi-user interaction technique is observed to be good in terms of 3D object position accuracy and latency between the devices. Conclusion: AR technology provides a multi-user interactive environment for teaching and training in the human body anatomy.

Design and Implementation of Collaborative Management System for Effective Learning

Recently, the need for online collaborative learning in educational systems have increased greatly because of COVID-19 pandemic. The pandemic has provided an opportunity for introducing online collaboration and learning among instructors and students in Nigeria. Currently, several schools, colleges, universities in Nigeria have discontinued face to face teaching and learning. Many schools resorted to ineffective alternatives such as the use of televisions and radio programmes to carry out distance education (DE). These alternatives have challenges such as lack of monitoring and evaluation of students’ learning. Collaborative Learning Management System (CLMS) is a research project that aims to assist instructors in achieving their pedagogical goals, organizing course content, collaborating, monitoring, and supporting students' online learning. It is an interactive, online based as well as android based system that has been designed, implemented, tested. The system demonstrates that it is robust, interactive, and achieves the predefined goals. As a Software Development Approach, it was created using the Rapid Application Development (RAD) Methodology. It also provides a secured and reliable platform for the schools, colleges, and universities to implement an online learning system.

A voice-based annotation system for collaborative computer-aided design

AbstractIn this paper, we describe a voice-based interaction mechanism to annotate 3D models directly from a computer-aided design (CAD) modeling environment. The audio signal is captured and automatically transcribed to a textual 3D note, which is attached to the geometry and made available to other product information and business processes across the enterprise via a product data management system. Our approach provides a more natural and intuitive method to capture design and engineering knowledge that is particularly effective when large amounts of information need to be communicated. We discuss the rationale of the software architecture and the value of this modality for capturing knowledge in a collaborative engineering context. Finally, we examine the results of an experiment to validate our proposal. Our results show that 3D annotations are an effective mechanism to communicate design knowledge, which suggests the need for further developments in the areas of multimodal interaction methods and interfaces for CAD and collaborative tools.

Reducing Cognitive Load and Improving Warfighter Problem Solving With Intelligent Virtual Assistants.

Recent times have seen increasing interest in conversational assistants (e.g., Amazon Alexa) designed to help users in their daily tasks. In military settings, it is critical to design assistants that are, simultaneously, helpful and able to minimize the user’s cognitive load. Here, we show that embodiment plays a key role in achieving that goal. We present an experiment where participants engaged in an augmented reality version of the relatively well-known desert survival task. Participants were paired with a voice assistant, an embodied assistant, or no assistant. The assistants made suggestions verbally throughout the task, whereas the embodied assistant further used gestures and emotion to communicate with the user. Our results indicate that both assistant conditions led to higher performance over the no assistant condition, but the embodied assistant achieved this with less cognitive burden on the decision maker than the voice assistant, which is a novel contribution. We discuss implications for the design of intelligent collaborative systems for the warfighter.

Un calcul d'interfaces pour les grammaires attribuées gardées

We address the problem of component reuse in the context of service-oriented programming and more specifically for the design of user-centric distributed collaborative systems modelled by Guarded Attribute Grammars. Following the contract-based specification of components we devel-opp an approach to an interface theory for the components of a collaborative system in three stages: we define a composition of interfaces that specifies how the component behaves with respect to its environement, we introduce an implementation order on interfaces and finally a residual operation on interfaces characterizing the systems that, when composed with a given component, can complement it in order to realize a global specification. Nous abordons le problème de la réutilisation des composants dans le contexte de la programmation orientée services et plus spécifiquement pour la conception de systèmes collaboratifs distribués centrés sur l'utilisateur modélisés par des grammaires attribuées gardées. En suivant la démarche de la spécification contractuelle des composants, nous développons une approche de la théorie des interfaces pour les composants d'un système collaboratif en trois étapes: on définit une composition d'interfaces qui spécifie comment le composant se comporte par rapport à son environnement, on introduit un ordre d'implémentation sur les interfaces et enfin une opération de résidus sur les interfaces qui caractérise les systèmes qui, lorsqu'ils sont composés avec un composant donné, peuvent le compléter afin de réaliser une spécification du système global.

The presence of e-books as digital books can be accepted by users because of the interactive content and display. However, the current format of e-book has not provided a mechanism/platform that accommodates contemporary learning styles on a two-way networked learning basis. E-books are more static in the sense that it has minimal interaction context. E-books have not been able to integrate learners with their learning environment in an interaction construct to support a learning activity. To address this problem, this study recommends a new approach called context-aware and collaborative mobile learning system design model. The method used in implementing the design model is design thinking . Usability testing using the guerrilla usability testing method is carried out to determine the quality of the e-books produced. The results obtained at the stages of empathize and define produced list and learning problems experienced by students when using e-books. The ideate and prototype stages produced e-book prototypes developed based on context-aware and collaborative mobile learning system design model. In the test stage, usability testing of 30 students showed good results. It is said to be good because there are no assignments with a score of one in the rubric usability testing table. So it can be concluded that the design model applied to the prototype e-book is feasible and can be understood by users . 800x600 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4

Virtual Collaborative Design Environment: Supporting Seamless Integration of Multitouch Table and Immersive VR

Throughout the design of a new building it is essential that all involved stakeholders understand, communicate, participate, and collaborate with each other to acquire a high-quality result. To support these shared and creative design processes, this paper presents the design and evaluation of virtual collaborative design environment (ViCoDE) - a new collaborative design system. ViCoDE features seamless integration of several immersive VR systems and a multitouch table that facilitates collaborative and interactive design work with immediate feedback. The evaluation of the system has been done during two real-life collaborative design workshops in a context of designing new healthcare environments. The results show that the VR system and multitouch table complement each other very well by facilitating both collaborative, and individual design spaces - and that it fosters better understanding, participation, communication, knowledge sharing, and collaboration among the different stakeholders. The contribution is two-fold: presentation of a new collaborative design system and the evaluation of its use in a real-life design context, which demonstrate how these new technology-based workshops may facilitate design management.

Design and Implementation of a Collaborative Design System for Ships

Liu, F.; Li, Y., and Hao, R., 2019. Design and implementation of a collaborative design system for ships. In: Li, L.; Wan, X., and Huang, X. (eds.), Recent Developments in Practices and Research on Coastal Regions: Transportation, Environment and Economy. Journal of Coastal Research, Special Issue No. 98, pp. 104–109. Coconut Creek (Florida), ISSN 0749-0208.Ship design and construction are complex processes, requiring collaboration between multiple disciplines. Professionals from different fields need to communicate in real time and solve problems through concerted efforts. This paper begins with a brief overview of the collaborative design system (CDS) for ships, and then sets up a CDS for shipbuilding projects based on the relevant theories. Next, the overall framework, login mode, access control, data storage, and main design of the proposed CDS were detailed one by one. The analysis shows that the proposed CDS enhances the manageability and flexibility of the ship design, reduces the design cycle, and enhances the design efficiency.

Issues and Experiences in Building Heterogeneous Co-Editing Systems

Most past research efforts in co-editing focused on homogeneous co-editing, which allows multiple users to use the same editor to edit shared documents in the same session, and nearly all real-world co-editors, such as Google Docs, are homogeneous co-editors. In this work, we explore issues and solutions in building heterogeneous co-editing systems, which allow multiple users to use different editors to edit shared documents in the same session. To drive our exploration, we built a prototype heterogeneous co-editing system, named CoVim+CoEmacs, which allows multiple users to use full functionalities and UI features of two comprehensive and rivalry text editors, Vim and Emacs, in the same co-editing session. In this paper, we focus on technical issues in designing and implementing heterogeneous co-editors in general and CoVim+CoEmacs in particular. We have motivated this work by potential usage benefits of heterogeneous co-editing systems and used working scenarios under the CoVim+CoEmacs prototype to illustrate some novel usages and inner workings of such systems, but left systematic user studies on heterogeneous co-editing to future work. We hope the insights and experiences drawn from this work can not only contribute to advancing state-of-the-art collaborative system design and implementation, but also provide inspiration to future heterogeneous collaborative application system designers.

Mapping strategies for distributed, social and collaborative design systems of makers, designers and social entrepreneurs

The practice of designers has recently evolved from a relatively closed ecosystem of professional actors to an ecosystem with less clear boundaries and roles. Makers can be considered (and often are) designers or a new kind of designers working with open, peer-to-peer, distributed and DIY approaches. And both makers and designers increasingly work with social innovation initiatives, becoming thus social entrepreneurs or collaborating with them. Where are makers, designers and social entrepreneurs, how many are there, how do we reach them and network them? This article presents a first exploration of literature, cases and datasets that represent direct or indirect approaches for mapping where they can be found. These formal or informal approaches are clustered in three groups: work, place and community. Each dimension generates a different perspective with different approaches and datasets, which influences our view and definition of makers, designers and social entrepreneurs.

Virtual reality in manufacturing: immersive and collaborative artificial-reality in design of human-robot workspace

ABSTRACTOver the past years, the concept of human-machine interaction has received ample attention to achieve hybrid automation in manufacturing. A form of hybrid automation is taking benefit from the synergistic effect of human-robot collaboration. When used in assembly, the requirement of flexibility, adaptability and safety makes the design and redesign of human-robot collaborative (HRC) systems a complex and prone to error process. The use of time-based continuous simulations can offer safe virtual space for testing and validation thus easing the design of complex HRC systems. However, conventional simulations don’t allow to experience the future production system as an end-user in an immersive environment. This paper explores the technological development in virtual reality (VR) for design of human-centred production systems and develops a unified framework to integrate human-robot simulation with VR. The simulation as an event-driven simulation helped in estimating the human-robot cycle times, developing process-plan, layout optimisation and robot control program. The same simulation is used in VR to interact with the production equipment and particularly with the robot. Additionally, AWS Sumerian environment is used to create a virtual robot to assist VR user in the design process.

"It doesn't win you friends"

Collaborative writing tools have become ubiquitous in today's world and are used widely in many professional organizations and academic settings. Yet, we know little about how ability-diverse teams, such as those involving people with and without vision impairments, make use of collaborative writing tools. We report on interviews with 20 academics and professionals who are blind or visually impaired and perform collaborative writing with sighted colleagues. Our findings reveal that people with vision impairments perform collaborative writing activities through four interconnected processes, which include learning an ecosystem of (in)accessible tools, adapting to complexities of collaborative features, balancing the cost and benefit of accessibility, and navigating power dynamics within organizations. We discuss how our analysis contributes to theories of accessibility in collaboration and offers practical insights for future collaborative system design.

Land Cover Mapping in Data Scarce Environments: Challenges and Opportunities

Land cover maps are a critical component to make informed policy, development, planning, and resource management decisions. However, technical, capacity, and institutional challenges inhibit the creation of consistent and relevant land cover maps for use in developing regions. Many developing regions lack coordinated capacity, infrastructure, and technologies to produce a robust land cover monitoring system that meets land management needs. Local capacity may be replaced by external consultants or methods which lack long-term sustainability. In this study, we characterize 9 and respond to the key land cover mapping gaps and challenges encountered in the Lower Mekong (LMR) and Hindu Kush-Himalaya (HKH) region through a needs assessment exercise and a collaborative system design. Needs were assessed using multiple approaches, including focus groups, user engagement workshops, and online surveys. Efforts to understand existing limitations and stakeholder needs resulted in a co-developed and modular land cover monitoring system which utilizes state-of-the-art cloud computing and machine learning which leverages freely available Earth observations. This approach meets the needs of diverse actors and is a model for transnational cooperation.

Consumer-centered collaborative design of fashion clothing brands: a communication and organizational structure study

abstractAfter analyzing the organizational structure and communication of three original Chinese fashion clothing brands, researchers argue that collaborative design is useful for achieving a common goal, communicating, and sharing information among consumers and stakeholders from the brand. Researchers summarized the design process in three structure models as balanced group structure, unified group structure, and radial group structure. Based on the unified group structure, two experimental projects are adopted to examine how to keep communication working effectively in the brands’ organizational structure. The results and feedback from the two experimental projects show that collaborative design improved the quality of design service. The study proposes a communicating structure model and interacting with the consumer and group members (stakeholders) that contribute to the achievement of modular design and collaborative design system setup. The limitation of the study is that it has not covered all stakeholders of brands’ organizational structures and the model needs to be enhanced.

INVESTIGATING THE IMPACT OF RADICAL TECHNOLOGY ADOPTION INTO THE NEW PRODUCT DEVELOPMENT PROCESS

Product developers are increasingly often faced with the decision of whether or not to adopt new technologies into their own new product development (NPD) processes. Adopting a resource-based perspective, we posit that the adoption of radical technologies into the NPD process, such as remote collaborative design, virtual reality, and simulation systems, can help improve NPD performance. At the same time, these adoptions are likely to slow down product launch. Just as consumers struggle to integrate radical technologies during the short-term, we propose that new product developers will face a similar learning curve. Therefore, we investigate potential moderators that could help product developers quickly integrate radical technologies and lessen their negative influence on product launch timeliness. A wide-ranging survey of 249 product managers sponsored by an international product development organisation is used in this study. The results reveal that while the adoption of radical technologies benefits NPD performance, the adoption tends to slow down the product launch process. However, cross-functional leadership within the organisation helps to lessen this negative influence on launch timeliness. The results from this study offer product managers practical guidelines for successfully adopting radical technologies into the NPD process and mitigating risks.

Exploring Indie Game Development: Team Practices and Social Experiences in A Creativity-Centric Technology Community

The emergence of various interest-based online communities has led to the popularity of new forms of distributed creative teamwork such as citizen science, crowdsourcing, and open source software development. These new phenomena further complicate the context and content of distributed creative teamwork: what are the characteristics of these new forms of creative teams? And how do they shape people’s perceptions and social experiences of distributed creative teams? In this paper, we report our empirical research of the team characteristics and practices in a creativity-centric technology community (i.e., independent [indie] game development) in hopes of exploring these questions. Our findings show that 1) indie game development teams are formed upon shared aspirations and use various strategies to collaborate with friends or online strangers; and their team practices are achieved through a balance between individual creativity and collective vision as well as a collaborative learning for problem solving and self-improvement; and 2) these teams mediate new forms of social interaction and collaborative experiences, featuring a mix of online comradery and weak social ties, and a mix of self-confidence and self-confliction. Using this new dataset and research context, we confirm and extend existing theories of distributed creative teams in CSCW. We also argue that studying these small-scale, self-selected, and interest-based teams can inform the design of collaborative systems to support various creative teams’ social needs.

Design and analysis of an effective graphics collaborative editing system

With the rapid development of computer-supported cooperative work (CSCW) technology, graphical collaborative editing plays an increasingly important role in CSCW. The most important technique in graphics co-editing is the consistency of graphics co-editing, which mainly includes causality consistency, consistency of results, and consistency of intention. Most of the previous research was abstract and ineffective, lacking theoretical depth and scalability. However, because the algorithm proposed in this paper can solve the contradictions in the consistency of graphical collaborative editing, the research in this paper has particularity, and the results will be proven by the experiment described in the paper. In order to solve the consistency conflict problem of graphic collaborative editing, the common graphics collaborative editing algorithm (CGCE algorithm) is proposed. It is proposed not only to perfect and expand the definition of graphics collaborative editing but also to merge with HTML5 Canvas, WebSocket, jQuery, Node.js and other network programming languages and technologies. The graphic collaborative editing based on the design and implementation of this paper can effectively solve the consistency conflict problem of many users during the collaborative editing of graphics, which ensures that the graphics of each graphical collaborative editing interface is consistent and the collaborative work can achieve the desired effect.
