Item Open Access Data supporting: 'The influence of augmented reality interaction design on Pilot's perceived workload and situation awareness'(Cranfield University, 2022-11-23 15:59) Li, Wen-Chin; Zhang, Jingyi; Court, Samuel; Braithwaite, Graham; Kearney, PeterThis work explored the potential for Augmented Reality (AR) rendering information superimposed over the flight deck to increase a pilot€™s situation awareness (SA). This emerging technology introduced novel human-computer interaction paradigms that would have impact on pilot€™s cognitive demands.Item Open Access Design of a virtual reality framework for maintainability and assemblability test of complex systems(Elsevier, 2015-10-09) Marzano, Adelaide; Friel, Imelda; Erkoyuncu, John Ahmet; Court, SamuelThis paper presents a unique environment whose features are able to satisfy requirements for both virtual maintenance and virtual manufacturing through the conception of original virtual reality (VR) architecture. Virtual Reality for the Maintainability and Assemblability Tests (VR_MATE) encompasses VR hardware and software and a simulation manager which allows customisation of the architecture itself as well as interfacing with a wide range of devices employed in the simulations. Two case studies are presented to illustrate VR_MATE's unique ability to allow for both maintainability tests and assembly analysis of an aircraft carriage and a railway coach cooling system respectively. The key impact of this research is the demonstration of the potentialities of using VR techniques in industry and its multiple applications despite the subjective character within the simulation. VR_MATE has been presented as a framework to support the strategic and operative objectives of companies to reduce product development time and costs whilst maintaining product quality for applications which would be too expensive to simulate and evaluate in the real world.Item Open Access The influence of augmented reality interaction design on Pilot's perceived workload and situation awareness(Elsevier, 2022-11-04) Li, Wen-Chin; Zhang, Jingyi; Court, Samuel; Kearney, Peter; Braithwaite, GrahamThis work explored the potential for Augmented Reality (AR) rendering information superimposed over the flight deck to increase a pilot's situation awareness (SA). This emerging technology introduced novel human-computer interaction paradigms that would have impact on pilot's cognitive demands. The objective of this research was to evaluate both the pilot's perceived workload and SA while interacting with an AR device using different interactive modes. Participants performed traditional landing checklists as a baseline to compare with the AR gesture-command and voice-command checklists. The research results showed that gesture-commands created additional cognitive and physical demands. Conversely, voice-command checklists could constitute a significant improvement in terms of reducing participants' perceived workload and maximising SA performance. The findings provided evidence that the interactive modes of AR user interface design could influence participant's cognitive information processing and perceived workload in flight operations. However, there were some limitations with AR applications that included latency on response time, narrow field of view, accuracy of voice recognition, calibration within dynamic environment and inexplicable movements of the head position that required further investigation. An AR device can be a great tool for training at the initial stage to increase cost-efficiency in flight operations. Furthermore, the implementation of an AR design may provide part of the potential solution for single pilot operations in the future.Item Open Access A review of digital twin technologies for enhanced sustainability in the construction industry(MDPI, 2024-04-16) Zhang, Zichao; Wei, Zhuangkun; Court, Samuel; Yang, Lichao; Wang, Shuozhi; Thirunavukarasu, Arjun; Zhao, YifanCarbon emissions present a pressing challenge to the traditional construction industry, urging a fundamental shift towards more sustainable practices and materials. Recent advances in sensors, data fusion techniques, and artificial intelligence have enabled integrated digital technologies (e.g., digital twins) as a promising trend to achieve emission reduction and net-zero. While digital twins in the construction sector have shown rapid growth in recent years, most applications focus on the improvement of productivity, safety and management. There is a lack of critical review and discussion of state-of-the-art digital twins to improve sustainability in this sector, particularly in reducing carbon emissions. This paper reviews the existing research where digital twins have been directly used to enhance sustainability throughout the entire life cycle of a building (including design, construction, operation and maintenance, renovation, and demolition). Additionally, we introduce a conceptual framework for this industry, which involves the elements of the entire digital twin implementation process, and discuss the challenges faced during deployment, along with potential research opportunities. A proof-of-concept example is also presented to demonstrate the validity of the proposed conceptual framework and potential of digital twins for enhanced sustainability. This study aims to inspire more forward-thinking research and innovation to fully exploit digital twin technologies and transform the traditional construction industry into a more sustainable sector.
