Abstract: Industry 5.0 arises as a logical advance of Industry 4.0 to enhance the values that were being gradually abandoned due to the rapid technological advancement. These values focus on the human being, the sustainability and the continuity of the industrial system become the main objectives to be maintained during the development of the new smart industry model. These objectives allow the design of work environments within Industry 5.0 that ensure the adaptation of workers to technologies of Industry 4.0, in a sustainable way and that strengthen a resilient industrial system. In the present work the use of Value Sensitive Design (VSD) methodology for the redesign of manufacturing workplace in accordance with the values established by the Industry 5.0 is proposed. In this process, the VSD tripartite methodology allows to maintain the values of Industry 5.0 throughout the design process. Moreover, the integration of this methodology with the Axiomatic Design (AD) allows to achieve specific design parameters that meet the needs of the different stakeholders. The application of this model seeks the development of symbiotic work environments, in which workers increase their different physical, sensory and cognitive abilities with advanced technologies. The design of a work environment following the proposed model promotes a social smart industrial environment in which the safety and health of workers is ensured.

Abstract: Augmented Reality (AR) has started to be gradually utilized in industrial manufacturing. However, the gap between novel stage and industrial AR-based applications must be comprehensively solved. In this study, the task technology fit (TTF) and method of time measurement (MTM) are applied and put together to create a comprehensive map demonstrating the relationship between manufacturing tasks and AR-solution features. In addition, this map will support exploring the suitability of AR-based solutions and identifying the application areas of AR for industrial manufacturing, primarily focused on quality control, metrology and assembly tasks. By considering both the viewpoint of developers/users and the scientific principles underlying manufacturing tasks in this comprehensive map, the usability and effectiveness of the final AR solution are also ensured at an early stage of AR-based application development.As a result, this paper provides a useful system to utilize AR capabilities for more complex-multistep tasks in a standardized way. Thus, more potential development and improvement of AR-based solutions for quality 4.0, virtual metrology, and complex assemblies in an industrial manufacturing context could be holistically established and built.

Abstract: The assembly of an aircraft is executed by performing a series of assembly operations, which are carried out following specific instructions called work instructions. In addition, the quality control of these operations is performed following verification instructions. Traditionally, these work and verification instructions were based on 2D documentation (on paper or digital screen), prepared by manufacturing engineering, and made available to operators by manufacturing engineering systems (MES) when required. Over the last decade, Airbus has made significant progress in ensuring the digital continuity of processes, exploiting information from the industrial digital mock-up (iDMU) downstream, favoring the preparation and use of assembly and quality instructions through new techniques, such as lightweight 3D viewers, or augmented reality. This paper describes experiences of implementation of augmented reality (based on laser or holographic technology) in the workshop, both for assembly and quality processes. Several use cases are analyzed, comparing both technologies, explaining their pros and cons, and justifying the use of each of them in each process.

Abstract: Virtual reality (VR) and augmented reality (AR) have experienced a significant boom in recent years regarding their features and utility. They have become reliable tools that are applied in different fields and disciplines (medicine, industry, science, teaching, training, and robotics, among others). In the present research work, these technologies are used as tools for the training and maintenance of medical equipment. An application was developed using flexible programming and design software, such as Vuforia, Unity, SolidWorks, Visual Studio, and hardware such as smartphones and the HTC VIVE glasses. Considering the existing need and based on surveys carried out to medical and hospital technical staff, significant results were obtained about the use of AR and VR in the area of medicine. The use of interactive applications enables autonomous training, which may be executed at any time and it is also user-friendly; in addition, it enables achieving reduced maintenance time and improves the process of acquiring abilities, thus releasing resources for other purposes.

Abstract: Since the beginning of 2020, the Covid-19 pandemic has emerged in Indonesia and affected how people live, including the learning process. Schools and education institutions have been forced to move online. In addition, the places to support learning activities were closed as a precautionary measure against the spread of the virus, such as museums and historical sites. The education sector needs to rapidly develop and deploy a robust digital framework in dealing with the pandemic's effect. The 4.0 technological sophisticated development starts to pervade the learning process, such as augmented reality (AR). AR, which supports inclusive learning with interactive and attractive performance, can play an essential role in delivering profound understanding for students. This article presents the 3D historical enriched model of the Pawon temple derived from close range photogrammetry's point clouds that blends real and virtual environments. The 3D model of Pawon temple, which reached Level of Detail 3 (LoD3), can be accessed and perceived by users with augmented reality technology via Android-based devices.

Abstract: This paper presents the study and development of information feedback for human motor skill transferring system. The proposed system has an ability of capturing the demonstrator’s bimanual movement using Kinect which is the Microsoft’s sensing device. Then, the spatial and temporal data of the recorded movement will be encoded into the probabilistic model. When the learner wants to learn the demonstrator’s movement, the reproduced trajectory will be retrieved from the encoded model. After that, the augmented information guidance which is in the form of computer graphics using augmented reality technique will be presented to the learner during the practicing process. A virtual music performance is selected as the case study of transferring the demonstrator skill to the novice. The performance of proposed system guidance on the human motor skill transferring will be investigated. The experimental results indicate that augmented visual feedback leads to reducing the average position error of the novice’s movement with 67.2%. Moreover, 75% of the participants can improve their movement accuracies after being trained with augmented system guidance.
