This overview presents the current state-of-the-art of self-adaptive technologies within virtual reality (VR) training. Virtual reality training and assessment is increasingly used for five key areas: medical, industrial & commercial training, serious games, rehabilitation and remote training such as Massive Open Online Courses (MOOCs). Adaptation can be applied to five core technologies of VR including haptic devices, stereo graphics, adaptive content, assessment and autonomous agents. Automation of VR training can contribute to automation of actual procedures including remote and robotic assisted surgery which reduces injury and improves accuracy of the procedure. Automated haptic interaction can enable tele-presence and virtual artefact tactile interaction from either remote or simulated environments. Automation, machine learning and data driven features play an important role in providing trainee-specific individual adaptive training content. Data from trainee assessment can form an input to autonomous systems for customised training and automated difficulty levels to match individual requirements. Self-adaptive technology has been developed previously within individual technologies of VR training. One of the conclusions of this research is that while it does not exist, an enhanced portable framework is needed and it would be beneficial to combine automation of core technologies, producing a reusable automation framework for VR training.

“…The obtained results show that a VR environment has the potential to offer a more natural, powerful, economic, flexible platform than a traditional engineering environment to support assembly planning. Jayaram et al [18] have presented case studies in using immersive virtual assembly technology for projects in industry. The case studies selected real-life industry situations from industry members of the consortium and used the immersive virtual assembly technology to create a meaningful simulation.…”

Thoughtful consideration of products maintenance features early in design stage can reduce or eliminate maintenance costs, reduce downtime, and improve safety. As such, the effective collaboration of product designers and maintenance technicians throughout the product design process is becoming much more important for the most advanced competitiveness. To address this need, a visualization system that enables maintainability-related technicians cooperated with product designers in a networked manufacturing environment is proposed in this study. This paper presents a systematic approach to implementation of a Web-based visualization system by using virtual reality technology. The system aims at providing a simulated environment and concurrent engineering processes to facilitate communication, coordination, control, and integration of product maintainability validation and improvement activities. The result of this research will help increase product maintainability, reduce development cycle time and cost, and hence increase product marketability.

The scientific and industrial communities have begun investigating the possibility of making product recovery economically viable. Disassembly sequence planning may be used to make end-of-life product take-back processes more cost effective. Much of the research involving disassembly sequence planning relies on mathematical optimization models. These models often require input data that is unavailable or can only be approximated with high uncertainty. In addition, there are few mathematical models that include consideration of the potential of product damage during disassembly operations. The emergence of Immersive Computing Technologies (ICT) enables designers to evaluate products without the need for physical prototypes. Utilizing unique 3D user interfaces, designers can investigate a multitude of potential disassembly operations without resorting to disassembly of actual products. The information obtained through immersive simulation can be used to determine the optimum disassembly sequence. The aim of this work is to apply a decision analytical approach in combination with immersive computing technology to optimize the disassembly sequence while considering trade-offs between two conflicting attributes: disassembly cost and damage estimation during disassembly operations. A wooden Burr puzzle is used as an example product test case. Immersive human computer interaction is used to determine input values for key variables in the mathematical model. The results demonstrate that the use of dynamic programming algorithms coupled with virtual disassembly simulation is an effective method for evaluating multiple attributes in disassembly sequence planning. This paper presents a decision analytical approach, combined with immersive computing techniques, to optimize the disassembly sequence. Future work will concentrate on creating better methods of estimating damage in virtual disassembly environments and using the immersive technology to further explore the feasible design space.
