Collaborative co-design and evaluation of an immersive virtual reality application prototype for communication rehabilitation (DISCOVR prototype)

Interacting with virtual characters, objects and environments: investigating immersive virtual reality in rehabilitation

PURPOSE

This pilot study aimed to (a) investigate opportunities for immersive Virtual Reality (VR) technology in communication, physical, and visual rehabilitation by examining the interaction of people without disabilities in a range of structured virtual environments; and (b) validate research protocols that might be used to evaluate the physical, visual, and verbal interaction of users in virtual worlds, and their safety while using the technology.

METHODS

Thirteen adults identifying as people without disability were exposed to VR via a head-mounted display. A video-review method was used to qualitatively code and analyse each participant's communication, movement, orientation, and support needs.

RESULTS

All participants oriented to their virtual environments sufficiently to use applications. Their spoken language was effective for interaction, although unconventional social behaviours were also observed. Two participants reported minor adverse reactions consistent with mild cybersickness.

CONCLUSION

The results provide insight into the types of environments and characters that support the greatest communicative, physical, and visual interaction in immersive VR. The tested protocols are useful to assess safety when using VR, and to observe communicative, physical, and visual interaction with virtual environments and characters. Implications for future research and use of VR with people with communication, physical and visual disability are discussed.

Digital technologies to unlock safe and sustainable opportunities for medical device and healthcare sectors with a focus on the combined use of digital twin and extended reality applications: A review

Medical devices have increased in complexity where there is a pressing need to consider design thinking and specialist training for manufacturers, healthcare and sterilization providers, and regulators. Appropriately addressing this consideration will positively inform end-to-end supply chain and logistics, production, processing, sterilization, safety, regulation, education, sustainability and circularity. There are significant opportunities to innovate and to develop appropriate digital tools to help unlock efficiencies in these important areas. This constitutes the first paper to create an awareness of and to define different digital technologies for informing and enabling medical device production from a holistic end-to-end life cycle perspective. It describes the added-value of using digital innovations to meet emerging opportunities for many disposable and reusable medical devices. It addresses the value of accessing and using integrated multi-actor HUBs that combine academia, industry, healthcare, regulators and society to help meet these opportunities. Such as cost-effective access to specialist pilot facilities and expertise that converges digital innovation, material science, biocompatibility, sterility assurance, business model and sustainability. It highlights the marked gap in academic R&D activities (PRISMA review of best publications conducted between January 2010 and January 2024) and the actual list of U.S. FDA's approved and marketed artificial intelligence/machine learning (AI/ML), and augmented reality/virtual reality (AR/VR) enabled-medical devices for different healthcare applications. Bespoke examples of benefits underlying future use of digital tools includes potential implementation of machine learning for supporting and enabling parametric release of sterilized products through efficient monitoring of critical process data (complying with ISO 11135:2014) that would benefit stakeholders. This paper also focuses on the transformative potential of combining digital twin with extended reality innovations to inform efficiencies in medical device design thinking, supply chain and training to inform patient safety, circularity and sustainability.

Utilizing Virtual Reality for Gender-Affirming Voice Training: Surveying the Attitudes and Perspectives of Potential Consumers

BACKGROUND

Undertaking voice and communication training is an important part of the gender-affirming journey for many trans, gender-diverse and non-binary individuals. Training supports the alignment of voice with gender identity helping to reduce gender dysphoria as individuals are better able to connect with their voices. However, for training to be effective, regular practice is needed and the demands of training can often be difficult to meet.

AIMS

To investigate the interest, attitudes and perspectives on the use of immersive virtual reality (VR) to support gender-affirming voice and communication training by transgender, gender non-binary and gender-diverse people, and speech-language pathologists providing gender-affirming voice and communication training.

METHODS & PROCEDURES

A mixed-methods survey (i.e., collecting quantitative data through multiple-choice question and qualitative data through free text questions) was hosted online from 23 August to 21 September 2021. A total of 17 questions asked about technology use, and attitudes and perspectives towards VR. The survey included video examples of three different voice-activated VR applications to prompt participant responses about the technology.

OUTCOMES & RESULTS

A total of 70 survey responses were included in the analysis. All participants had previous experience using smart phones, but only 27.2% had previously used VR. Four key themes were identified relating to potential uptake of VR in gender-affirming voice and communication training: (1) general audience appeal, (2) perceived therapeutic value, (3) exposure to or protection from harm and (4) relatability to real life.

CONCLUSIONS & IMPLICATIONS

VR games may represent a viable option to support practice of voice exercises. Gamification through VR is likely to motivate some to increase frequency of practice. VR applications that are used in voice training need to be fit-for-purpose, and detailed co-design is necessary to build appropriate applications for future use. This study provides a foundation to inform the design, development and implementation of VR applications to be used in gender-affirming voice training.

WHAT THIS PAPER ADDS

What is already known on the subject? Speech-language pathologists work closely with transgender and gender-diverse individuals to help them achieve gender congruent voice and communication. Clients need to undertake regular and ongoing practice outside of training sessions to achieve and maintain their ideal voice. Motivation and adherence to regular practice sessions remain an ongoing challenge. What this study adds to the existing knowledge This study explores the use of immersive VR technologies to create safe, motivating and enjoyable environments to encourage regular practice of gender-affirming voice and communication exercises. It engages stakeholders in an early-stage participant-involved design to gauge interest in, and perspectives on, VR and technology-based training support tools. The results suggest that voice-activated VR applications would highly motivate some individuals if they were appropriately designed but would not be ideal for all. What are the actual and clinical implications of this work? Immersion in VR can be a highly motivating tool to enhance adherence to practice schedules for some individuals. However, tools need to be specifically designed with outcomes in mind to be fit-for-purpose, to support individual goals and to minimize the risk of harm. The few existing VR voice-activated applications that are available require further assessment, and redesign through co-design with users to functionally and safely support gender-affirming voice and communication training.

Social connectedness and the role of virtual reality: experiences and perceptions of people living with dementia and their caregivers

PURPOSE

People living with dementia are often at increased risk of becoming socially disconnected due to dementia-related challenges. In recent years, digital technology has been designed to help address the social health of people living with dementia and provide opportunities to promote or maintain their social connectedness. This paper presents the findings from phase two of a participatory action research project, which explored people living with dementia and their caregiver's experiences and perceptions of social connectedness and the potential role of Virtual Reality (VR) in promoting or maintaining same.

MATERIALS AND METHODS

People living with dementia (n = 8) and their informal caregivers (n = 8) participated in an individual, 1:1 online interview. Data analysis was guided by reflexive thematic analysis.

RESULTS

The findings presented four themes: social connectedness: lived experiences and insights, facilitating social connectedness, barriers to social connectedness and the potential of multi-user VR for social connectedness. People living with dementia experienced a range of personal, community and societal connectedness. Facilitators of social connectedness included supportive, non-judgemental, and reciprocal relationships, technology adoption, and personal and contextual facilitators. Dementia-related difficulties and periods of disruption or change were considered barriers to social connectedness. Multi-user VR was perceived as useful for promoting and maintaining social connectedness.

CONCLUSIONS

The perceived usefulness of multi-user VR for social connectedness indicates its potential for use with this population. Understanding the lived experiences, barriers, and facilitators of social connectedness will assist researchers and the human-computer interaction community to inform the design of future multi-user VR for social connectedness outcomes with people living with dementia and their caregivers.

Exploring Discussions About Virtual Reality on Twitter to Inform Brain Injury Rehabilitation: Content and Network Analysis

BACKGROUND

Virtual reality (VR) use in brain injury rehabilitation is emerging. Recommendations for VR development in this field encourage end user engagement to determine the benefits and challenges of VR use; however, existing literature on this topic is limited. Data from social networking sites such as Twitter may further inform development and clinical practice related to the use of VR in brain injury rehabilitation.

OBJECTIVE

This study collected and analyzed VR-related tweets to (1) explore the VR tweeting community to determine topics of conversation and network connections, (2) understand user opinions and experiences of VR, and (3) identify tweets related to VR use in health care and brain injury rehabilitation.

METHODS

Publicly available tweets containing the hashtags #virtualreality and #VR were collected up to twice weekly during a 6-week period from July 2020 to August 2020 using NCapture (QSR International). The included tweets were analyzed using mixed methods. All tweets were coded using inductive content analysis. Relevant tweets (ie, coded as "VR in health care" or "talking about VR") were further analyzed using Dann's content coding. The biographies of users who sent relevant tweets were examined descriptively. Tweet data networks were visualized using Gephi computational analysis.

RESULTS

A total of 260,715 tweets were collected, and 70,051 (26.87%) were analyzed following eligibility screening. The sample comprised 33.68% (23,596/70,051) original tweets and 66.32% (46,455/70,051) retweets. Content analysis generated 10 main categories of original tweets related to VR (ie, advertising and promotion, VR content, talking about VR, VR news, general technology, VR industry, VR live streams, VR in health care, VR events, and VR community). Approximately 4.48% (1056/23,596) of original tweets were related to VR use in health care, whereas 0.19% (45/23,596) referred to VR in brain injury rehabilitation. In total, 14.86% (3506/23,596) of original tweets featured commentary on user opinions and experiences of VR applications, equipment, and software. The VR tweeting community comprised a large network of 26,001 unique Twitter users. Users that posted tweets related to "VR in health care" (2124/26,001, 8.17%) did not form an interconnected VR network, whereas many users "talking about VR" (3752/26,001, 14.43%) were connected within a central network.

CONCLUSIONS

This study provides valuable data on community-based experiences and opinions related to VR. Tweets showcased various VR applications, including in health care, and identified important user-based considerations that can be used to inform VR use in brain injury rehabilitation (eg, technical design, accessibility, and VR sickness). Limited discussions and small user networks related to VR in brain injury rehabilitation reflect the paucity of literature on this topic and the potential underuse of this technology. These findings emphasize that further research is required to understand the specific needs and perspectives of people with brain injuries and clinicians regarding VR use in rehabilitation.

Rehabilitation Supported by Immersive Virtual Reality for Adults With Communication Disorders: Semistructured Interviews and Usability Survey Study

BACKGROUND

Individuals who have acquired communication disorders often struggle to transfer the skills they learn during therapy sessions to real-life situations. Immersive virtual reality (VR) technology has the potential to create realistic communication environments that can be used both in clinical settings and for practice at home by individuals with communication disorders.

OBJECTIVE

This research aims to enhance our understanding of the acceptance, usefulness, and usability of a VR application (SIM:Kitchen), designed for communication rehabilitation. Additionally, this research aims to identify the perceived barriers and benefits of using VR technology from the perspective of individuals with acquired communication disorders.

METHODS

Semistructured interviews and usability surveys were conducted with 10 individuals with acquired neurogenic communication disorders aged 46-81 (mean 58, SD 9.57) years after trialing an immersive VR application. The audio-recorded interviews were transcribed and analyzed to identify themes.

RESULTS

The quantitative data regarding the usability of the system associated with participants' immersion experience in the VR application were promising. Findings from semistructured interviews are discussed across five key thematic areas including (1) participant's attitude toward VR, (2) perceived usefulness of the VR system, (3) perceived ease of use of the VR system, (4) their willingness to continue using VR, and (5) the factors they perceived as challenges or facilitators to adopting this VR technology.

CONCLUSIONS

Overall, participants in this study found the VR experience to be enjoyable and were impressed by the realism of the VR application designed for communication rehabilitation. This study highlighted personally relevant, immersive VR interventions with different levels of task difficulty that could enhance technology uptake in the context of communication rehabilitation. However, it is essential that VR hand controller technology is refined to be more naturalistic in movement and able to accommodate user capabilities.
