1. Introduction
The world’s population is rapidly aging. In 2020, there were 1 billion people aged 60 years or older. By 2030, this number is projected to rise to 1.4 billion, meaning 1 in 6 people globally will be in this age group. By 2050, the population of those aged 60 and over is expected to double, reaching 2.1 billion. Additionally, the number of individuals aged 80 years or older is anticipated to triple from 2020 to 2050, reaching 426 million [1]. Social isolation and loneliness, affecting about a quarter of older adults, are significant risk factors for mental health conditions in later life [2]. Approximately 14% of community-dwelling older adults over the age of 55 experience depressive symptoms, and older adults over the age of 85 who are physically and socially inactive are at a higher risk of experiencing depressive symptoms [3]. Research has indicated that the engagement of the elderly in virtual social media platforms can enhance their feelings of community support and connection, leading to a rise in life satisfaction [4]. Older adults engage in online social networks, facilitating conversations with family, friends, and peers, and exchanging personal and emotional life stories, which in turn diminishes feelings of loneliness and enhances their chances for social connections. Furthermore, various web-based social media sites offer digital social engagements, including online games and communal conversations, aiming to enhance the social engagement of older adults and boost their overall well-being [5]. A study revealed that elderly individuals engaging in virtual social interactions enhance their social support and emotional interaction, leading to increased life contentment and joy [6]. Consequently, engaging socially online serves as an effective tool to enhance seniors’ life contentment [7].
By analyzing, viewing, or similar research, we found that some studies indicate that the application of virtual reality technology in the geriatric domain is still in its infancy, with a limited number of existing studies and a lack of unified norms and standards [8,9]. The article [10] suggests that the application of virtual reality technology in older users focuses on the health domains of rehabilitation, fall prevention, physical activity participation, and cognitive exercise. Although some studies have found positive impacts of virtual reality interventions, there is a need to further understand the feasibility and acceptability of virtual reality interventions in the elderly population [9]. The paper [11] identified a number of design considerations through a review of the relevant literature, covering design decisions from hardware to software to human–machine configuration [11]. Ref. [10] suggests that future virtual reality programming for older adults should include the use of larger text in the operator interface, lighter weight devices, increased physical interaction during use, and age-appropriate requirements.
Articles [12,13] found that virtual reality had a positive impact on improving balance and functional motor skills in healthy older adults, but these studies focused only on older adults without disabilities, so the findings cannot be generalized to older adults with disabilities [13]. Subjective willingness and experience were found to be important factors influencing the effectiveness of virtual reality use, but previous studies have not explicitly assessed these factors [12]. There may also be publication bias, as studies with positive results are more likely to be published [12]. This limits the breadth of the analysis as the number of included studies remains relatively small [12]. The study was published differently from previous studies.
Virtual reality technology can improve people’s ability to process emotionally rich life situations, but further randomized controlled trials are needed to clarify its effectiveness relative to non-virtual reality interventions [14]. Future research should focus on randomized controlled studies to draw conclusions across different populations (with or without cognitive impairment or in different life situations) [15].
Although virtual reality technology provides new entertainment and socialization opportunities for older adults, there are issues of comfort, ease of use, cognitive load, and physical and psychological demands [16]. However, these studies have not delved into how natural virtual representations affect social well-being indicators (especially loneliness and social connectedness), nor have they revealed the psychological processes underlying them [17]. Studies in this area have focused on the short-term effects of virtual reality use and lack in-depth research on long-term use [12,13,16]. The paper [17] mentions the need for further research to fill this gap in the future, and while it points out the shortcomings of the existing research, it does not offer specific solutions or recommendations to overcome these limitations. In addition, the paper does not provide an in-depth critical assessment of each study.
Since the 1990s, there has been a steady emergence of virtual reality technology. Following several years of evolution, it has evolved into a vital instrument in medical, educational, entertainment, and various other areas [18]. In recent years, virtual reality (VR) has been shown to be an effective tool to help older adults with physical training, such as improving balance and preventing falls through interactive simulations [19]. VR can allow for older adults to safely avoid obstacles, and exercise, increasing engagement and motivation. In addition, VR can also be used for cognitive training, helping to improve memory and concentration [20]. In terms of socialization, VR can help older adults connect with family and friends remotely, reduce loneliness through virtual activities such as social gatherings and virtual tours, rekindle their passion for life, and improve their overall quality of life [21].
With ongoing advancements and enhancements in VR technology, its usage among the elderly is steadily rising. The growing interest in how older users welcome and utilize VR technology has emerged as a key research subject [22]. Despite the widespread use of virtual reality among the elderly, it must be acknowledged that it has certain shortcomings. Firstly, the aged population might encounter physical health constraints like weak vision, hearing, and equilibrium, potentially influencing their utilization and interaction with VR gadgets [19]. Secondly, older adults could struggle with comprehending novel technologies and require additional instruction and assistance for proficient use of VR machinery [23]. Furthermore, older adults might be more wary of technology’s security and privacy [24], thereby necessitating their consideration in the design of VR applications to enhance their reception and contentment. Older adults’ unique anticipations and requirements for the accuracy and engagement in virtual settings necessitates tailoring VR applications based on their preferences and capabilities to boost their receptivity and interactivity [25].
When designing virtual reality (VR) applications for older adults, design principles are critical. Studies have shown that clear game flow and a pleasant first experience can significantly improve older adults’ acceptance of VR technology [26]. In addition, adding social interaction elements, such as playing with friends or communicating in real time, can enhance older adults’ sense of engagement and belonging, thereby improving their acceptance of technology [27]. Content design should be tailored to the interests and cultural background of older adults, taking into account game difficulty, style, and background music to ensure that users have a pleasant experience [28]. At the same time, hardware design should adapt to the physical limitations of older adults, enhance their interactive experience, help narrow the digital divide, and promote technology use [29].
Generally, as VR technology continues to develop and become more popular, its adoption by the elderly is steadily increasing. VR, as a new technological means, can improve the social interaction experience of the elderly. Therefore, it is imperative to explore the user acceptance of social interaction of virtual reality technology among the elderly.
2. Background
In recent years, we have witnessed the development of virtual reality technology [30]. Research has explored immersive VR in health [31] by using virtual reality headsets to provide a fully immersive experience, placement stalking, and gesticulation-grounded controllers [32,33], suggesting that it may improve age-related cognitive impairment diseases or other physical health problems, such as stroke and dementia [34]. A large number of VR-applied interventions for older adults are currently being developed [35,36], and recent studies have shown a high quality of satisfactoriness regarding the safety of VR use in the elderly [37].
Nevertheless, applying VR to the medical field will result in the research field focusing only on the elderly with medical conditions, ignoring the potential benefits of VR for the elderly more generally. To provide possibilities in other areas, researchers have demonstrated that VR can serve as an entertainment medium for older adults [24,38], social media [39,40,41,42], or help for healthy ageing [20,43]. Nevertheless, till now, there is little research on VR application design for the ageing population [21], with notable exceptions [44]. Finally, while many researchers have developed VR solutions for the elderly, validation on solid, all-inclusive procedures for designing VR for the elderly is lacking [45].
As social aging accelerates, the demand for social interaction and entertainment among older adults is increasingly evident. Conventional social and entertainment methods are insufficient for the elderly’s needs; hence, identifying innovative technological tools to enhance their social interaction has gained significant importance. The advent of virtual reality (VR) technology as an entertainment tool introduces novel social interactions for seniors, garnering significant interest in its potential uses. Thus, a comprehensive analysis exploring how VR entertainment technology is embraced and its factors impacting older adults holds significant value in fostering their social engagement and entertainment enjoyment [46].
Virtual reality with social interaction can boost social engagement, cognitive skills, engagement, and emotional well-being in the elderly. Studies indicate that virtual reality can foster a 3D setting with a pronounced presence, contributing to resolving the social deficit experienced by seniors in digital interactions [47]. Moreover, the application of virtual reality technology may aid in enhancing cognitive training, potentially leading to positive improvements in the cognitive capacities of older adults. Engaging via social VR technologies is linked to the essence of real-life in-person communication, enhancing the engagement and joy of the elderly. Consequently, the influence of social interactive VR on the health of the aged is beneficial and is anticipated to emerge as a significant means to enhance the life quality of the aged population [48]. Exploring and discovering social VR environments for older adults is imperative.
A review of literature systematically helped us identify research works connected to the elderly’s experiences while using virtual reality technologies.

In Ireland, the journal with the most published articles was Archives of Gerontology and Geriatrics (n = 2). Other countries published in different journals. MDPI was the most popular publisher (n = 15), followed by Elsevier (n = 14).
Figure 1 shows the total number of VR-related articles published on older adults in the field of VR in the past decade, which is 225, and that number is trending upward, suggesting that traction is being gained in the VR for seniors space.
3.3. Analysis of Country
Figure 2 shows, among the top 100 most cited papers, the top 10 countries, regions, institutions, journals, and research categories that published the most papers. The USA (n = 35, 35%) published the most articles, followed by England (n = 28, 28%); third was Switzerland (n = 26, 26%), followed by Canada, Germany, and Ireland with (n = 7, 7%), (n = 6, 6%), and (n = 5, 5%), respectively; Australia, Hongkong, Italy, Lithuania, the Netherlands, New Zealand, and Spain published (n = 1, 1%) each.
3.4. Analysis of Keywords
Figure 3 shows a total of 266 keywords were extracted from the article. The most frequently occurring keyword is “Virtual Reality” (n = 91), followed by “Human” (n = 64) and “Age” (n = 61). Keywords are mainly divided into 5 groups: Group 1 (green) mainly involves virtual reality and older adults; Group 2 (red) mainly involves humans and age; Group 3 (blue) mainly involves controlled studies; Group 4 (purple) mainly involves the very elderly; Group 5 (yellow) mainly involves cognition. It can be seen that the research on the elderly and virtual reality is mainly to improve the cognitive training of the elderly and the treatment of other diseases through game therapy.
3.5. Analysis of Countries and Regions
The network mapping in Figure 4 helps authors discover the strength of citation links between two or more countries on similar documents. The distance between nodes is shorter, indicating a stronger correlation between them, leading to the conclusion that all countries can be divided into 5 groups: United States, South Korea and Taiwan (purple, cluster 1); United Kingdom, China, and Hong Kong (yellow cluster 2); Switzerland, France, and Japan (blue, cluster 3); Germany, Italy, and Greece (red, cluster 4); Australia and Denmark (purple, cluster 5). At the same time, the size of each country node in the visualization reflects the productivity of articles published in the process over the past 10 years. For example, the United States icon is the largest, which indicates that the number and quality of articles related to research in this field of virtual reality and the elderly are relatively high.
We can draw the following conclusion from Table A1 (Appendix A): Firstly, there is relatively more research on the elderly and VR technology in the United States and European countries, indicating that VR technology is in a leading position in the field of elderly care in these countries. Insufficient research in this field, especially in developing countries, may be due to the low popularity of VR technology in other countries and regions. In the future, we can explore the acceptance of VR technology among elderly people from different countries and economic backgrounds. Secondly, in terms of keywords, “virtual reality” and “elderly” appear frequently, but vocabulary related to cognition and rehabilitation also appears frequently, indicating that current research mainly focuses on cognitive and rehabilitation training. However, the keyword of social interaction hardly appears, which is a research gap. In the future, further research and discussion can be conducted on how virtual reality technology can help elderly people provide social support, especially with the intensification of social isolation issues after the COVID-19 pandemic. In addition, there is little research on the long-term impact of virtual reality technology on the elderly. In the future, long-term follow-up visits should be considered to clarify sustainability and effectiveness. Finally, virtual reality technology is mainly designed for young people and not specifically designed for the elderly. In the future, the development of VR devices will need to consider the usage habits of the elderly, such as more accessible interfaces.
4. Analysis and Outcome
Discovering and expanding on a topic first requires identifying and understanding the latest research trends in the field and the most influential research efforts. This paper aims to explore the importance of current research trends and locate the relevant literature related to the acceptance of virtual reality by older adults. We filtered according to the keyword of the title, and the main search keywords used were “Acceptance”, “virtual reality”, as well as “VR” and “older adult”. Seven studies were screened during the period and are summarized in Table 1. This work was motivated the following two research questions: Question 1—“What factors influence the acceptance of VR among older adults?” Question 2—“What are the theoretical frameworks in the study of VR acceptance among older adults?” To fully understand these challenges, we explored the recent literature as a primary source to answer these research questions.
4.1. Analysis of Virtual Environment and Older Adults
There were four research papers in the field of VR entertainment [26,27,29,50]; these included two studies on rehabilitation VR [28,49]; a study explored the prevention of falls [19]. All seven studies used VR headsets. While three studies did not mention the device used [19,27,49], a total of two studies used the HTC Vive [26,28]. One study explored the Oculus Rift [50], and another explored the Samsung Gear VR [29]. The test environments were mostly natural and living scenarios; the participants’ living situations covered a wide range of situations such as living with family, living alone, and living in a nursing home; and the average age of the test participants was over 60 years old.
Positive attitudes towards VR use amongst the ageing population are evidenced in all seven studies; six studies mention that education level has an impact on the acceptance of VR among older adults [19,26,27,29,49,50]. Older adults with higher levels of education are more inclined to embrace VR technology; people with higher levels of education usually have a greater capacity for learning and openness to new technologies, which makes them more likely to accept and use VR environments [29]. Four studies show that age affects the acceptance of VR devices in older adults [26,27,28,50]. Older adults may be less receptive to new technologies as they age because their expectations of how the technology will perform and the effort required to use it may not be as positive or little as those of younger adults; the younger the older the person, the greater the likelihood that he or she will use VR [50]. Four studies show that older adults are more likely to accept VR devices if they are easy to use [19,27,29,49]. Three studies have shown that if VR devices are helpful for their lives, elderly people are willing to use them [19,27,29]. Two studies have found that gender can affect older adults’ acceptance of VR [26,28], and additionally that men are more likely to accept VR than women [28]. Two studies found that although elderly people with cognitive decline may encounter difficulties in learning new technologies, their willingness to try new technologies is comparable to their peers with better cognitive status. Therefore, cognitive ability is not the main obstacle for elderly people to accept VR, but cognitive impairment may lead to risky behavior and interaction difficulties. The attention of the elderly to cognitive ability is lower than that to technical experience, but the potential impact of overall cognitive decline on the elderly’s attitude towards technology is not as important as the impact of technical experience [50]. There was discussion about the impact of health status on elderly people’s use of VR in two studies, one of which showed that elderly people with good physical health are more inclined to view the use of VR games positively. On the contrary, elderly people with poor health conditions may have a lower acceptance of VR games, as they may face more physical limitations and discomfort. Therefore, physical condition is one of the important factors affecting the elderly’s acceptance of VR games. [27] Another study suggests that poor physical condition may make them feel uncomfortable while using VR, such as experiencing symptoms like dizziness. This indicates that the health status of elderly people directly affects their experience and acceptance of VR games [26]. Two studies have found that more content related to the preferences of older adults can be more attractive for them to use VR, for example, virtual travel, learning new knowledge, reminiscing about beautiful times of the past, etc. [29,49]. Research has found that diverse games and content should be provided to meet the interests and needs of different elderly people. A study shows that social interaction can not only alleviate loneliness, but also enhance cognitive function in the elderly [49]. It is mentioned that the comfort level of wearing VR devices affects the elderly’s use of VR. For example, the weight of VR devices and the comfort of the materials used can affect the elderly’s choice to use VR [49]. There are also studies showing that elderly people who use VR experience a sense of achievement [27] and happiness [19], and they tend to prefer using VR. Two of the studies mentioned that when the elderly use VR equipment, advance training would have better results [27,49]; one study showed that correct instruction before the use of unaccustomed technology is supportive for elderly people [50]. Receiving help in using VR equipment can foster its quicker adoption [26]. Two of the studies believe that acceptance of VR equipment by the elderly is affected by computer proficiency [26,50]. More so, proficient computer use experience can make it easier for the elderly to accept VR. It is believed that the interface of the VR program affects the acceptance of VR equipment by the elderly [26,27]. The color, contrast, and interaction method of the interface affects the acceptance rate of VR by elderly people.
In recent research, seven studies have indicated the need for long-term observation to obtain better experimental feedback [19,26,27,28,29,49,50]. Current virtual reality technology is not limited to preventing falls but can also be expanded to other health fields related to the elderly, such as cognitive training, exercise rehabilitation, etc. [19]. In the future, the combination of virtual reality technology with other technologies, such as the Internet of Things, big data, etc., can be explored to provide more personalized fall prevention solutions [19], and more research is needed to explore its potential health benefits and practical application effects [27]. Seven studies suggest that future research should focus on cognitive training [19,26,27,28,29,49,50], in combination with other rehabilitation methods, [28,49] to evaluate the combined application effect of virtual reality technology and other cognitive training methods [28], promoting the healthy development of the elderly and improving their quality of life. Although virtual reality technology is rapidly developing, its application in the elderly is still relatively limited [27], and existing VR technology studies lack research on social, entertainment, and other aspects of life for the elderly [26,28]. In the future, virtual reality programs suitable for the elderly should be developed [49], and increasing the immersion and interactivity of VR technology is expected to further improve [28]. One suggestion is to design a universal virtual reality training system that adapts to a wider range of people to meet the needs of different populations [27,49]. Currently, research on the acceptance and usage habits of virtual reality technology in the elderly population is not sufficient, especially for the elderly [19]. Firstly, there is a lack of standardized measurement tools and evaluation methods [29,49]. Secondly, more research is needed in the future on the psychological and behavioral responses of the elderly population to the use of virtual reality technology, including overcoming physical and psychological barriers [26,50]. In addition, research on how to effectively apply VR technology in the elderly population still lacks considerations regarding comfort and safety [26], as well as efforts to reduce the potential side effects that may occur when using VR technology [26] like dizziness, etc. Finally, improving acceptance and the ability of elderly people to use VR technology through education and training are also important directions [50].
In summary, our future research on the application of VR technology in the elderly will focus on social interaction and cognitive training. By designing VR programs that meet the physiological and psychological needs of the elderly, and improving standardized measurement tools and evaluation methods, we aim to provide relevant training on VR technology for the elderly to enhance their acceptance of VR.
4.2. Case Analysis Acceptance of Gamified Virtual Reality Environments by Older Adults
Through research on case applications of VR equipment for elderly people, we have drawn some important conclusions: First, we found that elderly people showed positive attitudes and had pleasant experiences when using VR devices [27]. The virtual reality environment can also provide opportunities for social interaction for elderly people, promote their communication and interaction with others, help relieve loneliness and depression, and improve their quality of life [47]. Second, VR equipment can provide opportunities for physical activities and cognitive exercises, helping the elderly keep their minds sharp and their bodies healthy. By participating in virtual reality games and activities, they can perform mental training and physical exercise, enhance concentration and memory, and help prevent falls and cognitive function decline, as well as other accidental injuries [27]. In addition, VR equipment can also provide the elderly with more entertainment options, such as virtual travel, virtual games, etc., allowing for them to enjoy a colorful, entertaining life. This can not only alleviate loneliness in the elderly, but also stimulate their curiosity and add more fun to their lives [51]. Their high-rate acceptance of VR technology provides a positive reference for the future promotion of VR equipment among the elderly people.
Although the elderly find advantages in virtual reality devices, it is crucial to recognize the associated inherent challenges. At first, the costs associated with educating the elderly on utilizing VR devices surpass those of the youth. Elderly users might struggle to grasp a gadget’s functionality, including its usage and regulation systems, coupled with a lack of acquaintance with virtual reality’s principles, potentially hindering their educational progress and adaptation to emerging technologies. Subsequent studies indicate that older adults often suffer from unease, vertigo included, while operating VR devices [25,52]. Such discomfort could influence the degree of comfort and overall experience, potentially posing both mental and physical hazards to older VR device users. Considering the overall trend of diminishing cognitive and motor abilities in the elderly, they might confront an elevated risk with VR devices, potentially leading to a higher likelihood of falling [35]. Consequently, when advancing and implementing virtual reality (VR) devices for the elderly, a thorough awareness of health risks and appropriate preventative and safety strategies are vital for their protection.
Viewed from a wide angle, even though VR technology benefits the elderly, it is essential to identify health hazards related to VR, particularly in cognitive and motor skills. We propose these ideas regarding the design of VR equipment. To start with, elderly VR devices must be designed in a more straightforward and user-friendly manner, making the devices’ procedural options comprehensible and straightforward to minimize educational expenses and operational challenges [53], ultimately enhancing their adoption and readiness to engage with VR equipment [50]. Furthermore, in the promotion of VR devices, it is crucial to account for the features alongside the capabilities of an older demographic and create solutions that more fittingly satisfy these requirements. Ultimately, the significance of prolonged research and subsequent observations lies in understanding the perspective and alterations linked to older adults following prolonged VR device usage [26]. This approach will enhance comprehension of how older individuals embrace technology and serve as a vital source for future design strategies.
4.3. Question 1: What Factors Influence the Acceptance of VR among Older Adults?
Older adults face several barriers when using VR technology. Technical difficulties, such as intricate processes and the operation of devices, may reduce their receptiveness to technology [54]. Challenges like impaired attention, short-term memory, and motor coordination, which are cognitive impairments [55], demand that VR systems be built considering these limitations, thereby requiring systematic training and guidance [24,55]. Prolonged VR usage is further hindered by physical issues like reduced vision, hearing capacity, muscular strength, and balance, leading to experiences like dizziness and discomfort during prolonged headset usage [56]. For boosting the use of VR among the elderly, streamlining operations, offering training, and crafting devices that better suit their distinct requirements and constraints are crucial [56].
4.4. Question 2: What Are the Theoretical Frameworks in the Study of VR Acceptance among Older Adults?
There are many theoretical frameworks for acceptance, including Technology Acceptance Model (TAM), Technology Acceptance Model 2 (TAM2), Technology Acceptance Model 3 (TAM3), Unified Theory of Acceptance and Use of Technology (UTAUT), Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2), Unified Theory of Acceptance and Use of Technology: A synthesis of extensions (UTAUT: A synthesis of extensions), etc., which are widely used. Table 2 shows most of the relevant research on VR acceptance among the elderly adopts the TAM and UTAUT technology acceptance models.
4.5. Highly Cited Manuscripts on Virtual Reality
Table 3 shows the 10 most cited research articles on older adults in virtual reality over the past 5 years. The research area with the highest number of articles was medicine with six articles, followed by computer science with two articles; Huygelier et al. was the most cited article, followed by Liao et al. One study confirmed the benefits of VR devices in improving the physical health of older adults; three studies confirmed the benefits of VR devices in improving the physical health of older adults; one study confirmed the benefits of VR devices in improving learner engagement. These studies also face a number of challenges, such as small sample sizes and the possibility of expanding the studies to long-term assessments.
Although virtual reality technology can not only improve mild cognitive impairment and enhance physical health index in the elderly but also increase social participation to improve mental health, it can provide feasible intervention measures for language memory and daily life in the elderly. However, there are still shortcomings in the research on the use of VR technology by the elderly, such as a lack of studies on elderly people from different environments and backgrounds, and a scarcity of long-term observational studies.
5. Challenges
5.1. Technical Barriers
Among the challenges in implementing VR technology for older adults, technical barriers are an important issue [54]. Research shows that some elderly people may face complex operations of virtual reality devices, such as special controllers or headsets, which may lead to a decrease in their acceptance of technology [70]. In addition, some studies have also found that older people may be confused by complex operations in virtual environments, thus affecting their acceptance of virtual reality technology [45]. Therefore, when promoting virtual reality technology, attention should be paid to the technical obstacles that the elderly may encounter during use and take corresponding measures to simplify the operating process and improve acceptability of VR technologies among the ageing population [56].
5.2. Cognitive Impairment
As we age, older adults commonly encounter the challenge of cognitive impairment [71]. Research indicates that attention, short-term memory, and reaction time among the elderly tend to decline [72,73]. First, some older adults may face limitations in cognitive function, such as reduced attention to details and motor coordination [74]. This means that when implementing virtual reality technology, the cognitive level of the elderly needs to be taken into consideration to ensure that the virtual environment is designed not to cause distress or confusion to them [75]. Second, the elderly have limited rates of acceptance and adaptability to virtual reality technology [56], and they need systematic training and guidance based on their characteristics to improve their cognition and ability to use technology [10,35].
5.3. Physical Conditions
Older adults may face challenges in physical adaptation when using virtual reality technologies. Due to aging, first, older adults may experience a decline in physical functions and perceptual abilities [76], such as diminished vision, hearing, and muscle strength, as well as a gradual decrease in self-care abilities [70]. Second, the use of virtual reality devices may require head or full-body movements, and older adults may have limited motor abilities, especially those with motor impairments [77] or balance challenges [78,79]. In addition, older adults may experience dizziness and vertigo in virtual environments, which may affect their acceptance rate of virtual reality technology [80]. Finally, wearing headgear for long periods of time may put pressure on the head and neck, while gazing at the virtual reality environment for long periods of time may cause eye strain. Therefore, there is a need to investigate how to design comfortable virtual reality devices to alleviate the physical discomfort that older adults may face during use, thereby improving their experiences and acceptance rate [10].
5.4. Social Interaction
Although virtual reality technology has played a positive role in the medical field, including cognitive training and rehabilitation training, there is relatively little research on social interaction [81]. Social interaction is very important for people’s psychological and physical health [82], and it can effectively improve the loneliness caused by social isolation in the elderly. Virtual reality technology provides a safe social environment for the elderly, and new design experiences can help reduce anxiety and discomfort. Many studies have not delved into how VR technology enhances social interaction among the elderly; therefore, future research needs to further discuss the role of VR in enhancing social interaction among the elderly and its potential benefits. Researchers need to consider designing VR social programs that are suitable for the elderly and have a positive impact on their social interactions.
In summary, older adults may face a number of technical barriers to the use of virtual reality technology, including operational difficulties, device compatibility, health risk concerns, and a lack of digital technology knowledge. Cognitive barriers include memory loss that accompanies ageing and reduced attention span. There are also physical challenges such as vision loss as well as motion sickness. There is a lack of in-depth research on social interaction. Therefore, to address these challenges, the actual needs and characteristics of older adults need to be considered in an integrated manner in order to promote the healthy development of virtual reality technology for older people.
6. Suggestions and Recommendations
There has been a notable rise in the incorporation of virtual reality (VR) technologies across diverse fields such as healthcare, education, and entertainment in recent times. Yet, the embrace and utilization of virtual reality by the elderly, a group with distinct desires and obstacles, remain largely unexamined. It is essential to grasp the driving elements behind user acceptance to improve the practicality and efficiency of VR technologies tailored for this demographic.
Even though several studies have been identified regarding the uptake of VR by elderly users, certain facets warrant additional investigation: First, we found that there is still a lack of program personalization, and VR manufacturers do not pay attention to the interests of the ageing population enough, which affects the ease of use of VR for the elderly. In addition, due to the decline in physical function and perceptual ability of the elderly, the design of hardware needs to consider the material, weight of the device, volume level, and wearing comfort issues. In addition, professional help and usage guidelines have a positive impact on the acceptance of VR by the elderly.
In summary, future use of VR by the elderly should focus on enhancing social interaction and cognitive training. Social interaction and cognitive training are crucial to the health and quality of life of older adults. By utilizing VR technology, older adults can participate in a variety of social activities, including interactions with family and friends, thereby reducing social isolation and loneliness. In addition, VR can also be used for cognitive training, stimulating the brains of the elderly through various visual and interactive experiences to improve their cognitive abilities and life management skills. Therefore, future VR applications can focus more on how to help the elderly maintain a healthy, active and happy life through social interaction and cognitive training.
Finally, since there is a lack of social interaction in VR entertainment applications, older adults may be more socially oriented towards real interpersonal interactions and emotional exchanges, and the lack of social technologies in the VR entertainment experience may not be able to fully satisfy this need. Therefore, how to add more elements of real human interaction in VR social technology has become a problem that needs to be solved.
7. Conclusions
From the characteristics of the design and data on user experience derived from the chosen studies, certain key factors requiring attention in the development and trials of VR applications for the elderly can be pinpointed. Initially, enhancing the elderly’s use of VR technology can enhance their comprehension of VR and alter their perspectives on it. Additionally, enhancing VR technology can heighten its use among senior users. (1) Virtual reality technology’s design should account for potential cognitive and perceptual deficits in older adults. In the development of VR applications, the interface needs to be easy to understand and use to improve its usability. (2) In the realm of VR technology, the integration of virtual commands and efficient gesture recognition becomes crucial to meet the diverse tastes and requirements of the elderly and to guarantee the curation of appropriate VR materials. (3) Various online VR apps designed for older individuals require customization to suit their tastes and needs, aiming to attract more interest and enhance their interaction. (4) Wearing VR tools should be of equal importance. It is essential for apparatus to be crafted to be lightweight and comfortable to avert any discomfort due to extended use.
Essentially, it is feasible to increase the recognition of virtual reality technology among elderly users by providing social support. Providing support and education for the elderly can alleviate the difficulties they encounter when using VR technology. Future research should focus more on interdisciplinary integration, such as the integration of VR technology and psychology, which can promote the mental health of the elderly. With the cooperation of engineering, more lightweight and easy-to-use VR devices can be designed to enhance the elderly’s confidence and openness to these technological resources.
