Abstract

Purpose

The aim of this article is to provide details of recent technological developments in robotic teleoperation.

Design/methodology/approach

Following a short introduction, the two main sections of this article provide examples of recent research involving the application of virtual reality and haptic technologies, respectively, to robotic teleoperation. Brief conclusions are drawn.

Findings

Teleoperation systems are being developed which incorporate virtual reality and haptic feedback technologies. Those using virtual reality seek to enhance the operator’s feeling of immersion in the scene and improve their situation awareness and trials involving diverse tasks illustrate that the technology can achieve these aims and overcome many limitations of traditional systems. Haptic feedback further enhances the degree of operator involvement and control and is now being adopted in commercial minimally invasive surgical systems. Systems which combine virtual reality with haptic feedback are being developed and have the potential to allow operators to conduct increasingly complex tasks.

Originality/value

Through reference to recent research, this illustrates how virtual reality and haptic technologies are enhancing the capabilities of robotic teleoperation.

Abstract

Purpose

The purpose of this study is to design a highly integrated smart glove to enable gesture acquisition and force sensory interactions, and to enhance the realism and immersion of virtual reality interaction experiences.

Design/methodology/approach

The smart glove is highly integrated with gesture sensing, force-haptic acquisition and virtual force feedback modules. Gesture sensing realizes the interactive display of hand posture. The force-haptic acquisition and virtual force feedback provide immersive force feedback to enhance the sense of presence and immersion of the virtual reality interaction.

Findings

The experimental results show that the average error of the finger bending sensor is only 0.176°, the error of the arm sensor is close to 0 and the maximum error of the force sensing is 2.08 g, which is able to accurately sense the hand posture and force-touch information. In the virtual reality interaction experiments, the force feedback has obvious level distinction, which can enhance the sense of presence and immersion during the interaction.

Originality/value

This paper innovatively proposes a highly integrated smart glove that cleverly integrates gesture acquisition, force-haptic acquisition and virtual force feedback. The glove enhances the sense of presence and immersion of virtual reality interaction through precise force feedback, which has great potential for application in virtual environment interaction in various fields.

Abstract

Purpose

This study, which is a cross-sectional survey, aims to investigate health-care academics, clinicians and students’ perspectives of health-care simulation-based learning (SBL) and extended reality (XR) haptics use within health-care education. Participants’ views regarding the application, barriers and facilitators of SBL and XR haptics were explored.

Design/methodology/approach

The authors conducted an online international cross-sectional survey of 178 participants.

Findings

The survey found high health-care SBL use (n = 97, 55.1%) but low awareness (n = 48, 27.3%) or prior use of XR haptics (n = 14, 7.9%). Participants expressed interest in XR haptic technology emphasising its potential in SBL, particularly for understanding anatomy and physiology, enhancing clinical reasoning and consultation and practical skills.

Research limitations/implications

Whilst there was interest in XR haptics, few participants described previous experience of using this technology in SBL. A large percentage of the participants were UK-based. Most participants were from a nurse or physiotherapy professional background.

Practical implications

XR haptics is a developing technology for SBL in health-care education. Whilst there was clear interest from survey participants, further research is now required to develop and evaluate the feasibility of using this technology in health-care education.

Originality/value

Health-care students, educators and clinicians views on XR haptics have not previously been explored in the development and application of this technology. The findings of this survey will inform the development of XR learning scenarios that will be evaluated for feasibility in health-care SBL.

Abstract

Purpose

The current difficulties of distribution network working robots are mainly in the performance and operation mode. On the one hand, high-altitude power operation tasks require high load-carrying capacity and dexterity of the robot; on the other hand, the fully autonomous mode is uncontrollable and the teleoperation mode has a high failure rate. Therefore, this study aims to design a distribution network operation robot named Sky-Worker to solve the above two problems.

Design/methodology/approach

The heterogeneous arms of Sky-Worker are driven by hydraulics and electric motors to solve the contradiction between high load-carrying capacity and high flexibility. A human–robot collaborative shared control architecture is built to realize real-time human intervention during autonomous operation, and control weights are dynamically assigned based on energy optimization.

Findings

Simulations and tests show that Sky-Worker has good dexterity while having a high load capacity. Based on Sky-Worker, multiuser tests and practical application experiments show that the designed shared-control mode effectively improves the success rate and efficiency of operations compared with other current operation modes.

Practical implications

The designed heterogeneous dual-arm distribution robot aims to better serve distribution line operation tasks.

Originality/value

For the first time, the integration of hydraulic and motor drives into a distribution network operation robot has achieved better overall performance. A human–robot cooperative shared control framework is proposed for remote live-line working robots, which provides better operation results than other current operation modes.

Abstract

Purpose

Biofeedback is used for regulating vestibular adaptation and balance by providing real-time stimulus to the individual during physical activities. This study aimed at (1) developing a wearable device, which tracks balance, counts the number and the direction of balance losses and provides haptic biofeedback through real-time vibration stimulus (2) investigating device efficacy on an adolescent medulloblastoma patient during static and dynamic tasks.

Design/methodology/approach

A 16-year-old medulloblastoma patient used the device during 10-m walking and single-leg stance tests. The knee joint kinematics and the number and direction of balance losses were recorded for “with” and “without” biofeedback conditions.

Findings

The device helped regulate the knee joint kinematics and reduce the number of balance losses of the medulloblastoma patient. The knee joint movement pattern similarity of the control subject was highly correlated (R2 = 0.997, RMSE = 1.232). Conversely, medulloblastoma patient knee joint movement pattern similarity was relatively weak (R2 = 0.359, RMSE = 18.6) when “with” and “without” biofeedback conditions were compared. The number of balance losses decreased when the medulloblastoma patient was guided with biofeedback.

Research limitations/implications

The major limitation of this pilot study is the lack of a large and homogeneous number of participants. The medulloblastoma patient used the device while walking after she was given enough time to get used to the tactile biological feedback, so the long-term effect of the device and biofeedback guidance were not investigated. Additionally, the potential desensitization with prolonged use of the device was not evaluated.

Practical implications

Biofeedback reduced the number of balance losses; additionally, the knee joint movement pattern was regulated during static and dynamic tasks. This device can be integrated into the physical therapy of patients with balance, vestibular and postural control impairments.

Social implications

This is compact and has an easy-to-wear design, patients, who have balance and postural control impairments, can practically use the device during their activities of daily living.

Originality/value

The device promotes physical activity adaptation and regulates gait through continuous and real-time balance control. Its design makes it simple for the user to wear it beneath clothing while using the sensor.

Abstract

Purpose

The aims of this study are to explore how the experience of “visiting” a destination in a virtual reality (VR) technology environment influences destination image and visit intentions and to evaluate the moderating effects of the immersion level of the technology, destination familiarity and VR sickness.

Design/methodology/approach

An empirical study was conducted in a laboratory, using two types of immersive VR technologies. The data, collected through a personal survey of 144 participants, were analysed using PLS-SEM.

Findings

The results indicated that sense of presence is a crucial determinant of the user’s experience, which in turn contributed positively to destination image and visit intentions. VR sickness was observed to moderate the relationship between sense of presence and user experience, especially at low immersion levels. Destination familiarity did not influence the model’s relationships.

Practical implications

The findings lead us to propose that tourism destination managers: use immersive VR technologies in their marketing strategies; in these VR scenarios enhance the user’s sense of presence and experience and implement segmentation strategies.

Originality/value

This is one of the first works to empirically analyse how the customer’s experience of immersive technologies affects destination image and visit intentions. The study also evaluates three moderating effects: the effects of the level of immersion evoked by the technology, and destination familiarity, on the model’s relationships, and the effects of a negative aspect of the technology, VR sickness, on the relationship between sense of presence and the customer experience.

Abstract

Purpose

Augmented reality (AR) is revolutionizing the tourism and hospitality industry by offering immersive experiences as well as creating more engaging, informative and accessible travel experiences that attract tourists from around the globe. From virtual tours and immersive historical site recreations to navigation assistance and cultural education, AR technology is transforming the way we explore and interact with the destinations. This study aims to identify benefits, risks, tools and techniques of AR in the tourism and hospitality literature.

Design/methodology/approach

The authors conducted a systematic literature review to answer six research questions. The authors also identified 33 primary studies, dated from January 2010 to February 2024 and coded them via a thematic analysis. Related studies were obtained through searching in Web of Science and Scopus.

Findings

The results identified nine themes for benefits, eight themes for risks/disadvantages and four tools and applications-related themes. Through the thematic analysis, the major benefits of AR in the tourism and hospitality were found to be differentiated travel experiences, improved performance of tourism value chain, more effective marketing efforts of tourism businesses, enhanced tourists’ engagement, enhanced performance of tourism destinations, stimulated behavioral intentions, tourist empowerment and providing more value, interactivity and integrity. Furthermore, eight risks were identified: physical, privacy and security, social, service failure, technical, psychological, managerial, information and knowledge gaps. The authors also recognized four tools and applications-related themes, namely, AR-enabled tools, AR applications, AR-enabled apps and AR-based techniques.

Originality/value

To the best of the authors’ knowledge, this review provides the first systematic exploration of the existing literature on usage of AR in the context of tourism and hospitality value chain.

Abstract

Purpose

This study aims to investigate and propose guidelines to enhance the accessibility of virtual reality (VR) interfaces for all users within professional learning environments. Motivated by a lack of comprehensive accessibility guidelines for VR learning, the study delves into a case study of Edstutia’s VR campus.

Design/methodology/approach

This case study examines the intersection of VR platform development and learning experience design through the lens of accessibility in human-computer interaction. It elaborates on how user experience feedback from differently-abled learners who were unable to fully participate in the VR experience due to disability shaped the 2.0 version development of a VR platform.

Findings

The outcomes of this case study are (1) a description of an inclusive and empathetic design application to increase multi-learner VR platform accessibility, (2) a sample actionable path from a design/development perspective in ensuring the accessibility design of a VR learning platform, and recommendations to facilitate the design process.

Research limitations/implications

This case is a foundation for further research on improving accessibility in VR. In future work on VR campuses, we recommend scholars undertake research with an inclusive approach that actively involves users with different abilities in shaping guidelines, particularly on how individuals with different abilities should be approached for their input during the design and development process in a sensitive manner.

Practical implications

The authors summarize the steps taken to enhance the accessible interplay between the end users and the interface of VR technology in the emergence of VR accessibility standards. Central to this case’s exploration is the integration of accessibility as a pivotal element into an academic VR campus, i.e. multilearner education platform.

Social implications

Increasing access to VR has strong social implications in a world where 17% of people report a disability.

Originality/value

This case contributes to the limited research available on increasing access to VR on campuses.

Abstract

Purpose

In alignment with the European Union’s Vision Zero initiative to eliminate road fatalities by 2050, leveraging technological advancements becomes crucial for addressing the challenges of vulnerable road users (VRUs), and for mitigating the impact of human error. Despite increasing scholarly interest in applications of extended reality (XR), a research gap persists, particularly in the role of XR in transportation safety. Therefore, the aim of the study was to fill this gap through a systematic literature review to evaluate comprehensively the potential scope and practical applicability of XR technologies in enhancing the safety of VRUs.

Design/methodology/approach

A systematic review was undertaken, following PRISMA guidelines meticulously, in which 80 relevant articles from databases, such as Scopus and Science Direct, were identified and analysed.

Findings

The results of the analysis revealed the potential of XR beyond pedestrians and cyclists, and highlighted a lack of research about the impact of XR with regard to the personal traits or abilities of VRUs. The results of a thorough analysis confirmed the potential of XR as a promising solution for an approach to collaborative co-creation in addressing the safety challenges of VRUs. In addition, the integration of eye-tracking with virtual reality emerged as a promising innovation for enhancing the safety of vulnerable road users.

Research limitations/implications

Theoretical implications include enhancing the understanding of applications of XR in VRUs’ safety and providing insights into future research possibilities and methodological approaches. Valuable insights into search strategies and inclusion-exclusion criteria can guide future research methodologies.

Practical implications

Practically, the findings from the study offer insights to assist urban planners and transportation authorities in incorporating XR technologies effectively for VRUs safety. Identifying areas for further development of XR technology could inspire innovation and investment in solutions designed to meet the safety needs of VRUs, such as enhanced visualisation tools and immersive training simulations.

Originality/value

The findings of previous research underscore the vast potential of XR technologies within the built environment, yet their utilisation remains limited in the urban transport sector. The intricacies of urban traffic scenarios pose significant challenges for VRUs, making participation in mobility studies hazardous. Hence, it is crucial to explore the scope of emerging technologies in addressing VRUs issues as a pre-requisite for establishing comprehensive safety measures.
