Virtual reality for interactive training: an industrial practitioner's viewpoint

International Journal of Human-Computer Studies, 2001

The closing years of the 20th Century were associated with the advent of a!ordable Windows-based technologies for popular computer con"gurations, from powerful PCs in the home to workstations for small business communities. Such machines are readily capable of exploiting the power of real-time interactive 3D computer graphics, popularly referred to as virtual reality (VR). VR has rapidly evolved into a technology that today o!ers a cost-e!ective means of supporting the development of human skills in all manner of applications, from automotive engineering to defence, surgery to education, retail, petrochemical exploration, and heritage to micro-robotics. This paper reviews some of the important human performance results to emerge from the academic and commercial application of VR technologies, and notes some ergonomic issues to be resolved in developing techniques for training and performance assessment that can be used cheaply and e$ciently in industrial settings. 2001 Academic Press

Utilizing VR for Manufacturing Learning and Training

2021

This paper looks into the world of virtual reality as seen from the manufacturing point of view, specifically inside manufacturing education. Virtual reality is growing within many industries including manufacturing and is a key piece in Industry 4.0. Every year, the capabilities of virtual reality grow as the resolution of screens progresses to the point where it can simulate near-perfect depictions of reality as processing power continues to grow. This opens a massive amount of potential into things like training. Especially in the current environment where learning virtually has become the norm, being able to have hands-on experience can help education by a large margin. In this project a virtual reality environment was created in which those unable to or are simply interested can experience and learn how to utilize CNC machines. Working, visually appealing models of the laboratory machines were being constructed with machining models that can be implemented within them. Step-by-step instructions were created for the use of these models.

VRIT: An Innovative Approach of Industrial Training through Virtual Reality

The emerging global competition and increasing costs are a great challenge to industries. New cost effective training methods are explored to cope with this demand. In-depth knowledge of the functions in a factory is of vital importance for greater safety and better efficiency. Desktop and web-based e-learning applications offer industrialists new tools to raise maintenance-related knowledge and competence. Simulated learning through virtual 3D animations let employees comprehend the internal mechanisms of the equipment and the co-relation between the different parts. The evolution of Web technologies in recent years has enabled the use of Virtual Reality (VR) modelling for visualization of manufacturing processes creating a Virtual Environment (VE). The VR modelling language (VRML), which has become the standard for transmitting 3D virtual worlds across the Internet, can be used to control, interact and monitor manufacturing processes visually thus imparting training from a desktop computer. This paper deals with the simulation of the production of steel beams and columns presented to the subcontractors from a parent company.

From using virtual reality in the training process to virtual engineering

This paper firstly presents the reasons for virtual reality implementation, with immersion, in the processes of theoretical and practical training in the area of mechanics. There are some considerations related with the methodological implications and we propose an extension of the Wegener model. We describe a pilot station which tests the use of virtual reality in the training activities concerned. We present the first achievements in populating virtual settings, by interconnection of Cyber Gloves with the virtual setting, handling virtual parts for visual observation and easy assembling operations. Secondly, this paper describes a possible involvement of virtual reality to shift from traditional engineering to virtual engineering to resolve the current crisis of manufacturing engineering in a significant manner. Thus, we present the general structure of a virtual engineering entity, its main activities and organizational structures. Furthermore, we briefly review the main types of virtual reality equipment and technologies useful for highlighting virtual engineering for services and environment.

State of the art of the virtual reality applied to design and manufacturing processes

The International Journal of Advanced Manufacturing Technology, 2007

The idea that technology can transfer a person to a different environment without any physical movement and create the illusion of interaction with the artificial environment is not new. Scientists and engineers have been dedicating their efforts to its progressive development over the last fifty years. However, most of the technological advances have been made in the last ten years, undoubtedly thanks to improvements in computer efficiency and the miniaturization of sensorization devices. Nowadays, Virtual Reality is successfully applied in different fields, such as telemedicine, robotics or cinematography. Following on from this success, the question arises of whether we are ready to apply it to industrial design and manufacturing processes. The lack of recent reviews on this technology applied to CAD/CAM, together with its rapid evolution over the last decade, have been the primary motivations for carrying out this study.

Virtual Reality Based Digital Chain for Maintenance Training

Procedia CIRP

This paper presents ongoing research about the use of Virtual Reality (VR) to facilitate training for maintenance. VR systems are now widely accepted as training platforms for complex and highly demanding training tasks. In this paper, we focus on the application of VR technology for designing and evaluating the actual training process that relates to maintenance operations. Despite the availability of increasingly many and mature VR devices, it is still difficult to achieve the level of realism needed for the effective training of particular manipulation gestures that are vital for specific assembly and disassembly procedures. We propose a systematic approach to create a VR-based experimentation environment that facilitates the selection, calibration, and evaluation of different VR devices for the training of a specific maintenance operation. We present a case study to demonstrate the feasibility of our concept, as well as the huge potential VR has to even replace the traditional physical mock-up training. Via virtual hands, users can interact directly with virtual objects via various devices (mouse, keyboard and Leap Motion). Maintenance gestures can thereby be executed as naturally as possible and can be easily recorded to prepare maintenance learning service.

Virtual Reality System for Industrial Training

2007 IEEE International Symposium on Industrial Electronics, 2007

In this paper, a Virtual Reality Training system for maintenance of industrial equipment is presented. Since equipment are usually designed with CAD tools, it is feasible to create the Virtual Reality model. Despite of the virtual reality system itself, seting up an industrial related training system implies several processes in order to transform initial Computer Aided Design model into interactive models suitable for training processes. Our virtual training system is being developed following two main implementation approachs. On one hand a commercial tool (Eon Professional) is being used. On the other, the same system is being developed using open-source tools. Both approaches are described in this paper.

Using VR to improve design of assembly tasks and to increase efficiency in conducting the tasks

2018

In this paper we discuss how theories of vision, touch, sound, and learning behavior can form a basis for the development of a testbed through which real-life task performance can be compared with task performance in a Virtual Reality (VR) environment. By taking a multisensory approach, it will be possible to simulate the functionalities of a real training setting in a VR environment. Approaching this problem from a theoretical perspective, we will view it from a new angle and discuss whether we can enhance and nuance feedback in the virtual experience through the use of ambient media like sound, scent, heat, and wind. Sound may hold a great potential here. For visual perception, it is not only crucial that we can see relationships but that we are also able to search for patterns that we recognize. If an object is taken outside its context, its meaning can easily shift. To see is to search for patterns, but vision is also dependent on our experience of other senses. We can imagine how a given surface might feel by looking at a representation of the object, and this is because of previous tactile experiences with similar objects. From a technical perspective, integrating sound in a virtual environment is a straightforward process. Research shows that the process of learning a series of physical actions can be enhanced when it occurs in parallel with verbal or written information. In the literature, this phenomenon is described in terms of enactment or subjectperformed tasks. Based on theories regarding vision, touch, sound and learning behavior, we suggest the design of a testbed that can be used in a pilot study aimed at increasing knowledge on how VR and AR can support learning in an assembly or installation context in order to produce guidelines for such an environment.

An Immersive Virtual Reality Training System for Mechanical Assembly

Given the growing evolution of technology, machinery and manufacturing techniques, conventional methodologies for training the workforce are not enough for the current needs. Therefore methodologies capable to accelerate the training process and able to train the trainee in a wide range of scenarios are claimed for the industrial sector.
