**2. Literature review**

#### **2.1 Digital nature: digital activities and connectedness in cyberspace**

Digital nature is a promising and stimulating alternative to real nature for people with limited access to green spaces or who are housebound, such as during the global lockdown of COVID-19 [4]. A digital nature video and overall leisure activities of adults in the USA and their relationship to mental health were investigated based on a mixed analytical approach and revealed a positive impact of physical nature engagement on the subjective well-being of the participants [5]. On the other hand, when it comes to physical contact with nature, living far from nature is a significant predictor of loneliness scores, and short-term contact with nature does not significantly improve loneliness [6].

It has been suggested that contact with nature is important for mental and social well-being [7, 8] but that a certain "quantity" of interaction with nature is necessary, and that interaction with nature in digital space has a positive impact on people's well-being. This suggests that digital nature has great potential as a complementary strategy for people who are less mobile and have less frequent

contact with nature or interactions with others, or for older people with mobility difficulties [9–11].

### **2.2 Forest bathing in cyberspace: visual stimuli only vs. combined visual and auditory stimuli**

There is some debate about how interaction with digital nature materials contributes to well-being and mental health, including the differing effects of visual information (videos and photographs) and auditory information (sounds) [12]. Following the format of Song et al.'s [12] experiment, in the present study, a video of a forest stream was used as visual stimuli (**Figure 1**). Subjects participated in the experiment by viewing the experimental photographs in a free and relaxed atmosphere through a PC they were familiar with and were using regularly.

Next, they were given combined auditory stimuli, such as the rustling of trees in the wind and the murmur of a babbling brook. The stream sounds were made from high-resolution sound recordings. As with the visual stimuli, each subject received the composite stimuli through the screen and speakers of a familiar PC. Prior to the experiment, 10 participants were randomly selected as volunteers to listen to the participants' sensory evaluation of the intensity of the sound, which confirmed that they found this sound "easy to listen to."

The composite stimulus here, that is, the combined visual and auditory stimulus, was provided as a control stimulus with the option of quietly viewing a gray image without forest-derived stimuli. The study sought to ascertain subjective ratings of visual stimuli only vs. composite stimuli via (1) the evaluation of visual stimuli only vs. combined stimuli, and (2) the impact of the combined stimuli on the subject's transformation to environmentally oriented behavior. These were studied in a comparative manner.

#### **2.3 Potential of digital nature for smart tourism**

There is some debate about how interaction with digital natural materials contributes to well-being and mental health, including the different effects of visual information (videos and photos) and auditory information (sounds) [13]. This study states that when people's behavior was constrained in the COVID-19 era, online communities and gaming activities became more active and the impact of COVID-19

**Figure 1.** *Visual stimulation image.*

significantly changed people's lifestyle and behavior in the digital space. Oe [9] found that this feeling of connectedness with others led to positive impacts of cyberspace activities, and in the light of the behavior of digital natives, they valued the positive impacts of online gaming and other activities. In addition, digital natives are more likely to be more active if they can play online games in digital space, which has a positive impact on their efforts in light of digital native behavior, such as the healing of loneliness and emotional support from the new interactions created in the gaming community.

It is also known that in the COVID-19 era, there was an increased tendency to interact with nature and share videos and photos of transposed natural landscapes on social networking sites [14]. Furthermore, it has been found that people are more likely to engage in physical gardening and enjoy interacting with nature in neighborhood green spaces than before the pandemic [15].

So, can virtual tourism or digital nature smart tourism, with interaction with nature in digital space at its core, gain consumer support? And what segments of the population have affinity and purchasing intentions?

Pai et al. [16] and Ye et al. [17] discussed the role of smart tourism technology as one of the triggers to enhance the values of smart tourism experiences from a sustainable context. On the other hand, Dabeedooal et al. [18] highlighted that smart tourism can be a pillar of sustainable urban development; as Kontogianni & Alepis [19] stated, smart tourism is one of the popular topics in the tourism and hospitality sector. However, not many studies have examined the antecedents and behavioral patterns of smart tourism purchasing behavior of citizens and consumers based on empirical data.

#### **2.4 Analytical framework with scale**

Two factors, (i) respondents' environment-related activities in digital space, and (ii) virtual connections with others, were positioned as hypothetical antecedents, and the degree to which these two factors evoked respondents' "environment-oriented behavior" (direct effect) was examined (**Figure 2**). Next, as a mediating effect, respondents were asked to experience digital forest bathing indirectly, and the extent to which the degree of appreciation of digital forest bathing determined respondents' purchase intention was examined quantitatively (**Figure 3**).

### **3. Methodology**

#### **3.1 Survey design and data collection**

This study will use quantitative methods to test whether digital space activities and digital forest bathing influence citizens' purchase intention of smart tourism through a hypothetical route. As shown in **Figure 3**, the impact is examined using the relaxing effect of digital forest bathing as a mediating variable. A total of 300 valid responses were obtained to be used in the analysis, taking into account a balance of gender, age group, etc. The observed variables used in the model for hypothesis testing were shared from questionnaires obtained from previous studies and collected through a five-point Likert scale choice [20].

A questionnaire survey of individuals in Japan was conducted and validated. While there is an accumulation of studies focusing on digital forest bathing and human interaction with nature in cyberspace (mainly based on data sets from areas of developed economies), the latest data sets are in Japan, the birthplace of forest bathing (i.e., with restrictions on physical behavior due to COVID-19).

In the metropolitan area around Tokyo, the geographical distance to the deep forest is far, and it takes about two and a half hours one way to reach places, such as Okutama Forest, a well-known forest bathing area in the suburbs, which poses access issues. The questionnaire was translated into Japanese and subsequently finalized by two bilingual experts, following the process recommended by Brislin [21]. Three university professors and four volunteer Japanese citizens participated in the pilot test and the wording of the survey items was refined to improve the overall quality. The content was refined by improving the order of questions and wording. In the end, the survey reached 300 reciprocal respondents, with a balanced collection of gender, place of residence, work history, and annual income. The survey itself was conducted online, in view of the COVID-19 situation.

#### **3.2 Measures**

#### *3.2.1 Independent variables and dependent variables*

Measurements were made on the scale developed by Shen et al. [5] and Kryshtanovskaya and Lavrov [6], which is based on five items, including virtual activities and connectedness with others (two latent factors). Each factor consisted of

**Figure 4.** *SEM result of the direct model.*

five observed variables. The mediating variable (digital forest bathing) was considered two observed variables, based on the work of Song et al. [12]. Cronbach's alpha was employed as an indicator to test reliability, with each variable showing a desirable value of 0.8 or higher, indicating strong internal consistency.

The explained variables of the model consist of measures of the purchase intention of smart tourism of the subjects [22]. All items were measured on a five-point Likert scale. The scale ranged from "strongly disagree = 1" to "strongly agree = 5."

#### *3.2.2 Data analysis*

After cleaning the obtained data, the model was validated by semi-structural equation modeling using AMOS ver26. The model measured the impact of each factor on purchase intention of smart tourism through two patterns—a model measuring only the direct effect (**Figures 3** and **4**), which measures the impact of the antecedents on purchase intention of smart tourism using citizens' satisfaction with digital forest bathing as a mediating effect.

### **4. Findings and analysis**

#### **4.1 Data profile**

Prior to detailed analysis, it is necessary to examine the profile of the data set obtained. It was shown that a balanced data set was recovered by attribute (**Table 1**).

#### **4.2 Hypothesis testing**

#### *4.2.1 Validation of variables*

Once the indicators for the classification of respondents by personality have been completed and the procedures have been confirmed, it is time to test the hypotheses.


#### *Discussion of Purchasing Virtual Digital Nature and Tourism DOI: http://dx.doi.org/10.5772/intechopen.105869*

#### **Table 1.**

*Demographic profile.*

First, the consistency and rationality of the latent factors included in the model for analysis will be checked. For this purpose, factor analysis is conducted on the observed variables for purchase intention of smart tourism and antecedents. **Table 2** shows a descriptive analysis result of the data set.

A factor analysis was conducted and four factors were generated (**Table 3**). EDA means environmental digital activities, DFB means digital forest bathing, and VCC means virtual connectivity in cyberspace.

Once the process of ascertaining how each item can explain its own construct was completed, the next examination was conducted to identify whether the constructs were valid and reliable. The composite reliabilities (CRs) and average variance extracted (AVE) from the constructs were computed by statistical procedure [23]. These were estimated and are presented in **Table 4**.

As **Table 4** shows, the minimum CR and AVE values are lower than 0.7 [24] and 0.5 [25]. The square root of the AVE of each element, that is, the average variance (AV) is greater than the Pearson correlation coefficient between that construct and the other constructs. This means that the discriminant validity of the variables used here was confirmed. The value of Cronbach's alpha (CA) for each configuration is greater than 0.6,

which is the lowest acceptable value, meaning that, from here, the configuration of each variable is consistent [23, 26]. Correlation analysis was performed to check for the presence of multicovariances between the relevant factors comprising structural equation modeling (SEM). In other words, high correlations are not suitable for feeding into SEM, as they indicate multicollinearity between variables. The correlation coefficient should ideally not be higher than 0.7 [27]. Thus, the results of the convergent and discriminant validity test show that all values meet the relevant requirements and the constructs are reliable and consistent, so we can move to the next step of SEM analysis [23].

#### *4.2.2 Model of no-mediation*

Three contrasting models, no-mediation, partial mediation, and full mediation, were constructed to test the mediating effect. The control variables were also included

in the estimation with paths to the mediator and dependent variables [28, 29]. **Figure 4** shows the SEM results of the unmediated model, which includes three dependent variables—environmental digital activity, virtual connectivity in cyberspace, and purchase intention of smart tourism, hereafter referred to as EDA, VCC, and PIS. The results showed that the standard regression coefficient for the path of EDA and PIS was 0.221 (p < 0.05), while the path of VCC and PIS was 0.053 (p > 0.05). The covariance between VCC and EDA was 0.484 (p < 0.001). This implies that the latter path is not significant. The fitting index for this SEM model was GFI = 0.980 (>0.9), indicating a good model fit [26]. Also, **Table 5** shows the path coefficient of the direct model. In this direct model, hypothesis H1 was supported but not H2.

#### *4.2.3 Model of partial mediation*

As a mediating effect, digital forest bathing was placed in the center of the figure, hereafter referred to as DFB. The results show that the path from EDA to DFB was 0.649 (p < 0.001) and the path from VCC to DFB is highly significant at 0.476 (p < 0.001). Next, the path from DFB to PIS was 0.875 (p < 0.001). In other words, hypotheses H3, H4, and H5 are adopted. However, both paths of EDA to DFB and VCC to DFB were 0.085 (p > 0.05) and 0.017 (p > 0.05), respectively (**Figure 4**). This implies that both paths were not significant. Thus, H1 and H2 were rejected.

#### *4.2.4 Model of full mediation*

We followed the procedures outlined in Yu et al.'s [30] recent work, examining direct effects using SEM. The direct effects of EDA and VCC on BC were examined through DFB. **Figure 5** shows our research SEM model. **Table 6** shows the standardized regression weight, p-value, and percentile confidence level (PC) of 95% for all the direct

and indirect paths, which were based on 5000 bootstrap samples, for the direct effects perceived. The indirect effect of the path EDA to DFB to PIS shows 0.441 (p < 0.001, PC = 0.278 to 0.622) and VCC to DFB to PIS shows 0.323 (p < 0.001, PC = 0.139, 0.520). This implies that both paths are significant. Thus, H6 and H7 were supported.

Observing the goodness of fit of the SEM research model presented in **Figure 5**, the goodness of fit index (GFI) is 0.972 (>0.9) and the adjusted goodness of fit index (AGFI) is 0.938 (>0.9). The root mean square error of approximation (RMSEA) is

0.063 (<0.10), which is better than the specified value [26, 28]. In summary, the fit of the model is excellent.

#### **4.3 Discussion**

The SEM model of the "Digital Environment-Mediated Effects Model" for the two groups of introverted and extroverted samples shows that the GFI of the model, including the chi-square/degree of freedom, is above the desired level, and it can be evaluated that a model consisting of reliable measures has been presented.

As analyzed and discussed above, the hypothesized SEM model of digital environment effects on purchase intention of smart tourism can be assessed as presenting a model and scale consisting of reliable measures, as the indicators of goodness of fit, including chi-square/degrees of freedom, are above the desired level. And interestingly, even though the direct effect linked from EDA and VCC to PIS is

nonsignificant, when looking at the indirect effect through DFB, which is set as the mediating effect, both paths to PIS are significant. In other words, the results show that simple engagement with the environment and connection with others in the digital space does not foster interest in smart tourism, but familiarity with digital forest bathing stimulates people's interest and interest in smart tourism and stimulates their willingness to buy.

### **5. Conclusion**

#### **5.1 Theoretical contribution**

Focusing on the mediating effects of digital forest bathing, this study quantifies the impact of people's behavior and interactions in digital spaces on enhancing their purchase intention of smart tourism. As a rule of thumb, people tend to become more familiar with the digital nature and experience subjective well-being during the lockdown period of COVID-19 behavioral restrictions. This study quantitatively reveals the pathways through which people's behavior in digital spaces and digital forest bathing stimulates their interest in the digital environment and their willingness to purchase smart tourism.

The greatest contribution of this study is that it quantified the pathways through which people's behavior in digital spaces, through the mediating effect of digital forest bathing, leads to people's willingness to purchase digital tourism, and proposed practical measures and models.

#### **5.2 Practical contributions**

The results of this study are unusual in that they show the potential of forest bathing to provide a sense of well-being and stimulate their intention to enjoy digital tours, even in places where there are no forests. For example, it suggested the possibility of increasing subjective well-being through contact with DIGITAL nature through digital forest bathing, through tourism in cyberspace and the purchase of smart tourism to improve the health of elderly people living alone and people with mobility difficulties in the aging society of the future.

This also suggests new business opportunities for tourism businesses that have suffered disruptive impacts due to COVID. In this sense, the practical contribution of this study is also to propose supporting information for the development of smart tourism strategies.

#### **5.3 Future research tasks and limitations**

Although the study obtained results with a high potential for theoretical and practical contribution as described above, the authors are aware of several limitations. First, the size of the data set used for the analysis was not large, and the demonstration discards psychological aspects, such as the definition of smart tourism, the implementation of the technology, and the readiness of citizens for the technology. In the future, we plan to collect larger data sets to confirm and further refine the feasibility of the implementation of the number-r models and measures proposed by this study.
