Augmented and virtual reality are transforming the practice of healthcare by providing powerful and intuitive methods of exploring and interacting with digital medical data, as well as integrating data into the physical world to create natural and interactive virtual experiences. These immersive technologies use lightweight stereoscopic head-mounted displays (HMDs) to place users into simulated and realistic three-dimensional digital environments, unlocking significant benefits from the seamless integration of digital information with the healthcare practitioner and patient's experience. This review article explores some of the current and emerging technologies and applications in surgery, their benefits and challenges around immersion, spatial awareness and cognition, and their reported and projected use in learning environments, procedure planning and peri-operative contexts and in the surgical theatre. The enhanced access to information, knowledge, and experience enabled by virtual and augmented reality will improve healthcare approaches and lead to better outcomes for patients and the wider community.

The majority of the world's citizens now live in cities. Although urban planning can thus be thought of as a field with significant ramifications on the human condition, many practitioners feel that it has reached the crossroads in thought leadership between traditional practice and a new, more participatory and open approach. Conventional ways to engage people in participatory planning exercises are limited in reach and scope. At the same time, socio-cultural trends and technology innovation offer opportunities to re-think the status quo in urban planning. NeoGeography introduces tools and services that allow non-geographers to use advanced geographical information systems. Similarly, is there a potential for the emergence of a neo-planning paradigm in which urban planning is carried out through active civic engagement aided by Web 2.0 and new media technologies thus redefining the role of practicing planners? This paper traces a number of evolving links between urban planning, NeoGeography and information and communication technology. Two significant trends – participation and visualisation – with direct implications for urban planning are discussed. Combining advanced participation and visualisation features, the popular virtual reality environment Second Life is then introduced as a test bed to explore a planning workshop and an integrated software event framework to assist narrative generation. We discuss an approach to harness and analyse narratives using virtual reality logging to make transparent how users understand and interpret proposed urban designs.

Background: Without effective self-care, people with diabetic foot ulcers (DFUs) are at risk of prolonged healing times, hospitalization, amputation, and reduced quality of life. Despite these consequences, adherence to DFU self-care remains low. New strategies are needed to engage people in the self-care of their DFUs. Objective: We aimed to evaluate the usability and usefulness of a new mobile application to engage people with DFUs in self-care. Methods: We developed a new mobile application, “MyFootCare”, to engage patients with DFU through goal-setting, progress monitoring, and reminders in self-care. Key features included novel visual analytics that automatically extracts and monitors DFU size information from mobile phone photos of the foot. A functional prototype of MyFootCare was created and evaluated through a user-centred design process with 11 participants with DFUs. Data were collected through semi-structured interviews discussing existing self-care practices and observations of MyFootCare with participants. Data were analysed qualitatively through thematic analysis. Results: Key themes were: (1) Participants already used mobile phone photos to monitor their DFU progress, but (2) had limited experience with using smartphone applications. (3) Participants desired the objective DFU size data provided by the tracking feature of MyFootCare to monitor their DFU progress. (4) Participants were ambivalent about the MyFootCare goal setting and diary features, commenting that these features were useful but also that it was unlikely that they would use them. (5) Participants desired to share their MyFootCare data with their clinicians to demonstrate engagement in self-care and to reflect on their progress. Conclusions: MyFootCare shows promising features to engage people in DFU self-care. Most notably, ulcer size data is useful to monitor progress and engage people. However, more work is needed to improve the usability and accuracy of MyFootCare, i.e., by refining the process of taking and analysing DFU photos and removing unnecessary features. These findings open the door for further work to develop a system that is easy to use and functions in everyday life conditions, and to trial it with people with DFUs and their carers.

Purpose: Process modeling is a complex organizational task that requires many iterations and communication between the business analysts and the domain specialists. The challenge of process modeling is exacerbated, when the process of modeling has to be performed in a cross‐organizational, distributed environment. This paper aims to suggest a three‐dimensional (3D) environment for collaborative process modeling, using virtual world technology.Design/methodology/approach: The paper suggests a new collaborative process modeling approach based on virtual world technology. It describes the design of an innovative prototype collaborative process modeling approach, implemented as a 3D Business Process Modeling Notation (BPMN) modeling environment in Second Life. We use a case study to evaluate the suggested approach.Findings: Based on a case study application, the paper shows that our approach increases user empowerment and adds significantly to the collaboration and consensual development of process models even when the relevant stakeholders are geographically dispersed.Research limitations/implications: The paper presents design work and a case study. More research is needed to more thoroughly evaluate the presented approach in a variety of real‐life process modeling settings.Practical implications: The research outcomes as design artifacts are directly available and applicable by business process management professionals and can be used by business, system and process analysts in real‐world practice.Originality/value: This research is the first reported attempt to develop a process modeling approach on the basis of virtual world technology. It describes a novel and innovative 3D BPMN modeling environment in Second Life.

Eliciting accurate and complete knowledge from individuals is a non-trivial challenge. In this paper, we present the evaluation of a virtual-world based approach, informed by situated cognition theory, which aims to assist with knowledge elicitation. In this approach, we place users into 3D virtual worlds which represent real-world locations and ask users to describe information related to tasks completed in those locations. Through an empirical A/B evaluation of 62 users, we explore the differences in recall ability and behaviour of those viewing the virtual world via a virtual reality headset and those viewing the virtual world on a monitor. Previous results suggest that the use of a virtual reality headset was able to meaningfully improve memory recall ability within the given scenario. In this study, we adjust experiment protocol to explore the potential confounds of time taken and tool usability. After controlling for these possible confounds, we once again found that those given a virtual reality headset were able to recall more information about the given task than those viewing the virtual world on a monitor.
