Transportation Mobile Applications Adoption Behavior Does Affect Overseas Residents' Life Satisfaction: Involvement as A Moderator

Abstract Mobile application acceptance is an emerging research area that gained wide-spread popularity. Managerially important but the overlooked aspect is mobile applications adoption effect on overseas resident’s life satisfaction. Travel applications make users’ life easier with a smooth travel satisfaction that contributes to life satisfaction. The users who perceive applications useful and easy to use are satisfied with life in South Korea. Moderating effects of travelers’ involvement between three types of transportation applications and perceived usefulness and ease of use, where people use mobile applications before and during traveling, to fulfill travel needs, location detail, and to make the right arrangements were identified as moderator of technology adoption model (TAM). Data collected from 400 users conclude that relation of usefulness with travel satisfaction is not significant while residents perceive ease of use were significant determinants of travel satisfaction. TAM acceptance influences travel satisfaction which provides more feeling too satisfied from life.


Introduction
Life satisfaction has been investigated by scholars in numerous diverse disciplines, e.g., public health, tourism, and psychology. Previous research has used several methods to understand how different factors contribute to life satisfaction (Friman et al., 2017;C. C. Chen et al., 2016C. C. Chen et al., &, 2016, These studies provide a foundation for understanding the role of travel satisfaction with life overall well-being. For example, Friman et al. (2017) have theorized whether multiple purpose travel affects emotional well-being as well as life satisfaction; similarly, Dittmann and Goebel (2010) have examined how socioeconomic status of neighborhood aspects affects life satisfaction. Furthermore, the authors revealed that during travel, "relaxation" is a better predictor of life satisfaction (C. C. Chen et al., 2016). Additionally, X. Chen et al. (2019) found that cross-cultural social adaptation significantly associated with overseas life satisfaction. However, to the best of our knowledge, there have been few research studies about involvement (Josiam et al., 1999;Dedeoğlu, 2019;Choi et al., 2020) and augmented reality (AR) TAM adoption behavior to examine overseas resident's life satisfaction.
Research has revealed that how user acceptance of the technology can be accurately explained to enhance life satisfaction, which strongly associated with everyday activities (Köttl et al., 2020). TAM acceptance can be explained by acceptance of perceived usefulness and perceived ease of use. Perceived ease of use plays a significant role in technology acceptance because it increases users' experience ( Van der Heijden, 2004). Modern increase of mobile applications has been revolutionized the way people experience their surroundings to enhance the overall experience of traveling, a recent study explored the opportunities of using augmented reality to enhance the travel experience; British female travel application acceptance depends on favorable attitude towards perceived usefulness and perceived ease of use. So, to identify the potential of applications, it is essential to examine technology acceptance and augmented reality (AR) mobile applications acceptance behavior of users (Tom Dieck & Jung, 2018).
The literature has ignored the impact of different mobile application acceptance behavior to measure travel satisfaction and life satisfaction for overseas. How comfortable and easy to travel overseas residents feel by living abroad. Mobile applications acceptance is the most rapidly growing technology invention worldwide. Previous research has mainly investigated the relation of travel experience to life satisfaction by using different methodologies ; this study provides in-depth understanding of modern mobile travel applications acceptance behavior that influence overseas residents travel satisfaction and life satisfaction in South Korea.

Transportation mobile applications impact on AR technology adoption
Transportation takes much importance because travelers rely on Buses, Taxis or Cars in their daily life and work, selection of transportation mode based on factors such as time to reach the destination or so on, similarly person traveling in bus or subway thinks that from where the traveler should get off to find a taxi? Taxi mobile-based applications enable users to make informed transportation decisions, taxi application delivers a piece of real-time availability information to mobile users, taxi application equipped with GPS devices also monitors traffic condition around the traffic stand in the particular area, in this way people can decide the best place for them to get a taxi and they can also decide whether they should take bus or subway first in their ways (Wu et al., 2012). So, our study selected mobile booking taxi application (Kakao Taxi) to examine technology acceptance for rental taxi transportation.
Travelers have difficulties moving around independently (Sánchez & Oyarzún, 2011); bus applications for the mobile devices are designed to help people to take public transportation, purpose to design bus application is to be notified where and when the next bus is coming (Banâtre et al., 2004). Buses generally convey a huge number of passengers and goods available for public benefit (Voon et al., 2016). Current study examined the acceptance behavior of Kakao bus application used by residents for daily routine travel purpose in South Korea.
Transportation applications provide updated information to travelers, mobile communication devices getting priority comprises an application over the wireless medium, besides mobile communication devices, transmits and receives traffic congestion update data as they pass within communication rage similarly mobile navigation application predicts traffic flows, traffic patterns, and compute routes from current position to target destination (Tzamaloukas & Farmwald, 2004). So, study examined acceptance behavior of Kakao Navi application that allows travelers to plan trips by travelling in personal transportation.
Researcher have examined that the Technology acceptance model (TAM) is used to predict behavioral intention to use information system depends upon perceived ease of use and usefulness of websites that connect people through social networks (Rosen & Sherman, 2006). Based on past research literature study attempts to develop a model that will explain the acceptance of modern mobile travel applications (Kakao Navi, Kakao Bus, Kakao Taxi).
Significant research has been done on mobile-based applications, current smartphone ranges from navigators to digital cameras as well as GPS-based and becoming the commanding platform for technology acceptance (Tom Dieck & Jung, 2018). To boost traveling experience usage of applications plays an important role, with the emergence of updated applications; travel organizations can enhance the traveler satisfaction and experience (Leue et al., 2014). Perceived usefulness and ease of use cause travelers' to accept or reject invented mobile application, traveler's use the specific application if they believe it will help to perform their travel better, easy to use application is more likely to be accepted by users (Davis, 1989).
Our study seeks to determine whether invented travel applications can assist in traveling by considering it useful and easy to use for traveler's in South Korea. Therefore, we proposed the following Hypotheses: Hence, the proposed hypothesis of the study is initiated: H1: Public transportation application type A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi) positively influenced to the Perceived Usefulness.
H2: Public transportation application type A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi) positively influenced to the Perceived Ease of Use.

Perceived ease-of-use impact on perceived usefulness
Perceived usefulness and perceived ease of use are two variables in the technology adoption model (TAM) that influence intentions to use technology (Subramanian, 1994). Several lines of research discussed Perceived ease of use and usefulness developed by Davis (1989) play a major role to influence the usage of information, level of usage accurately explain the critical importance of various technologies (Segars & Grover, 1993). In perceived usefulness person believes that using a technology would enhance performance, while in perceived ease of use persons believe that using a particular technology would be free of effort and easier to use lead to more accept by the users (Davis, 1989). Researchers concluded that perceived usefulness and perceived ease of use helps to formulate intentions for technology acceptance (Ramayah & Ignatius, 2005). Furthermore, the authors, Gefen and Keil (1998) examined the positive influence of ease of use on the Perceived Usefulness. However previous research has not identified perceived ease of use related to perceived usefulness in case of transportation application types and their overall influence on overseas life satisfaction. The researcher concluded that application must be easy to use for people (Adams et al., 1992;Gefen et al., 2003;Sengars & Grover, 1993;D. W, 2006).
The effect of perceived usefulness and perceived ease of use has been explored by many researchers (Gefen et al., 2003;Ramayah & Ignatius, 2005;D. W, 2006). However, the literature lacks empirical evidence on whether the travel application perceived ease of use impact the perceived usefulness to formulate application acceptance behavior. Therefore, we proposed the following Hypotheses: H3: Perceived ease of use of Public Transportation Application A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi) have a positive impact on Perceived Usefulness.

The influence of perceived usefulness and ease of use on travel satisfaction
In introducing TAM, mobile application ease of use and usefulness plays important role in user's satisfaction, users who consider the tool easy to use and useful shows positive attitude which increase their intentions to use the application, usefulness is related to the quality of tool while content delivery and interface are the focus of ease of use (Joo et al., 2011); Perceived usefulness has a direct effect on satisfaction. To measure travel satisfaction with TAM acceptance, perceived usefulness and ease of use are especially important ways, so travelers consider application easy to use will consider it useful (Calisir & Calisir, 2004).
Travelers get support from mobile-based applications, to provide an enjoyable experience of travel, newly developed applications provide valuable information, (Davis, 1989;Tom Dieck & Jung, 2018). Usefulness and easy to use of applications within the transportation industry is determined and seen a positive acceptance behavior, Transportation application influence the intentions of travelers to use the application useful in assisting with trips planning (Niemand & Chauke, 2017; literature have ignored the overseas user's application acceptance (TAM) on travel satisfaction (Foth & Schroeter, 2010;Korbel et al., 2013). Therefore, we proposed the following Hypotheses:

Mobile applications
The use of mobile applications has become increasingly popular which has significantly transformed modern life Schilit et al., 1993). Over the last decade, the rapid development of mobile phones has resulted in devices with more sophisticated operating systems increasing mobile-based applications designed for traveler's, application used to interact and engage with information daily (Niemand & Chauke, 2017). In recent years, lifestyle of people has been changed with the development of applications; the usefulness of travel applications has increased greatly allowing users to perform more tasks in a friendly environment, a wide range of applications to be developed with the advances in mobile technology which users want to use while on the move (Harrison et al., 2013). With the development of travel applications, traveler's life has become much easier (Hussain et al., 2018).
Many researchers have examined mobile applications usability (Baharuddin et al., 2013;Harrison et al., 2013;Hussain et al., 2018) in different contexts, but there is limited research about mobile application impact on acceptance in the context of overseas life satisfaction.
Therefore, we proposed the following Hypotheses: H7: Public Transportation Application A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi) have a direct impact on life satisfaction.

Travelers' involvement
The Author (Li, 2014), pointed out Involvement is a psychological state of motivation, interest, or encouragement among individuals or groups, it changes from behaviors and have a strong relation with involvement, high or low involvement can be seen in different consumer behavioral studies.
In a variety of ways, the involvement construct has been approached, Involvement refers to the strength of individual's cognitive structure to a focal object, the interaction between individuals and objects, which relates to individuals' perceptions of importance and relevance of shown behavior, involvement has been shown to have a moderating effect on variables to analyze loyalty (Chen & Tsai, 2008) while study ignored the moderating relation of involvement for TAM.
Involvement gained a lot of importance, previous research proposed behavioral modes and explained involvement concepts with different perspectives (Poiesz & Cees, 1995;Zaichkowsky, 1986) the authors emphasized on the degree of arousal of involved individuals concerning goal-related object represents the intensity of involvement. Similarly, the author (Chen & Chen, 2010) suggested that for traveling activities that need participation, the attraction was considered the most influential factor. While, the authors C. C. Chen et al. (2016) suggested that relaxation is considered a better predictor of life satisfaction during traveling. In Another study (Bian & Zhu, 2020) explored the relation of travel involvement with travel intention, the authors concluded that involvement is considered the most important component of travel experience while the study ignored the moderation relation of travelers' involvement with technology acceptance context. However, literature ignored the gap on overseas life satisfaction with the acceptance of travel application; the moderating role of traveler's involvement has remained mostly unconnected. Therefore, we proposed the following Hypotheses: H8: Traveler's involvement moderates the relation between transportation applications A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi) and perceived usefulness.
H9: Traveler's involvement moderates the relation between transportation applications A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi) and perceived ease of use.

Travel satisfaction impact on life satisfaction
Satisfaction is linked to personal emotions used to measure travel behavior and suggested that traveling utility may be considered a proxy for traveling behavioral satisfaction. Previous research has investigated satisfaction with work and satisfaction with daily travel (Friman et al., 2017;Skurzak et al., 2020). At the same time, travel behavior studies have focused on travel costs, travel experiences, and behavioral intentions, satisfaction with public transport can have an impact on people's general quality of life and subjective well-being (Lunke, 2020;McCarthy & Habib, 2018).
It is well known that the attention on overseas resident's population is increasing, relatively few studies have considered an alternative solution to this problem and conducted research with the perspective of foreign residents (Kang et al., 2020;Anderson, 2020;Izawa & Oka, 2020;(O. B. Smith, 2013;Bergstad et al., 2011;Friman et al., 2017). Travel satisfaction has been linked to life satisfaction but no previous research exists for overseas resident's life satisfaction (Waygood et al., 2019). Therefore, we proposed the following Hypotheses: H10: For public transportation application type A (Kakao Bus), type B (Kakao Taxi), type C (Kakao Navi); travel satisfaction has a positive influence on overseas resident's life satisfaction.
The relationship among travel application type and Mobile application acceptance (AR Tech), travel satisfaction and traveler's involvement and overseas resident's life satisfaction is illustrated in Figure 1.

Sample and data collection
The sample was composed of 400 overseas residents' participants from South Korea; we surveyed the second largest city in South Korea, Busan (Ahn et al., 2016) and attractions for foreigners because of its beaches. The participants were asked about their residency in South Korea because of participation condition; residency in South Korea for more than one year, the residency of all overseas participants was confirmed before data collection. Regarding gender distribution of the total participating, sample (N = 400), most of the respondents were male (57.8%; n = 169) while 42.3% were female (n = 231). In descending order, students (35%), self-employed (19.7%), government employee (16.8%) and participants belonging to other occupations (28.5%) were included in the survey. Of all respondents, 0.5% were less than 20 years of age, 39% were between 21 and 30, 41% were between 31 and 40, 15.2% were between 41 and 50, and 4.2% declared they were above 50 years of age.

Research instrument
To gather information about the participants' life satisfaction measurement of constructs were adopted from existing literature. The questions were structured along a seven-step scale. Based on stated definitions, scale and literature initial scale items were generated. The five questions were drawn for traveler's involvement scale from the handbook of Marketing scale (Bearden et al., 1999); perceived ease of use and perceived usefulness items obtained from the existing scale (Van der Heijden, 2004); moreover, four items for travel satisfaction scale and three items for life satisfaction scale developed by C. C. Chen et al. (2016).

Validity and reliability tests
We used the software SPSS (version 22.0) AMOS (Version 21.0) to perform Cronbach alpha, and CFA, Path Analysis procedure was applied and hypotheses were tested. To access the reliability and validity of the research constructs confirmatory factor analysis (CFA) was conducted. Then a Structural regression model was used to find out the influence of public transportation mobile applications (Kakao Bus, Kakao Taxi and Kakao Navi) impact on TAM model (perceived usefulness and perceived easy to use) adoption behavior; Furthermore, travel satisfaction impact analyzed to know its influence on life satisfaction, also moderator influence of travelers' involvement was examined and tested all hypotheses.
Guidelines suggested by (George, 2011) Cronbach-alpha (0.8 ~ 0.9) of all variables indicate a good internal consistency, after confirming Fit Indices, validity, and reliability of variables and To test the internal consistency of the variables in the component we calculated Alpha and C.R. Results show that C.R and Cronbach-α most values are high and both are more than 0.7 and the difference is also very less; see, Tables 1 and 2. The model composed of variables Application types (Kakao Bus, Kakao Taxi, Kakao Navi), traveling involvement, perceived usefulness, perceived ease of use, travel satisfaction, and life satisfaction, to analyze reliability and validity CFA was performed with all constructs in Table 1. All the indicators have significant factor loadings between 0.7 ~ 0.9 while the significant correlation between constructs was above the required value; in Tables 3 and 4, results are supported by previous research (Fornell & Larcker, 1981a), results   Table 3.

and H7
After confirming validity and reliability of constructs we evaluated the structural model, in support of hypotheses for Public transportation application types, firstly we investigated the influence of transportation application type A (Kakao Bus), Type B (Kakao Taxi) and Type C (Kakao Navi) on Perceived usefulness and perceived ease of use, as Table 4a, shows, results confirmed a significant positive influence of Type A (Kakao Bus) application on Perceived Usefulness (β = 0.202, S. E = 0.073, T = 2.785, **P < 0.01), In Table 4b, Type-B (Kakao Taxi) impact on Perceived Usefulness (β = −0.058, S. D = 0.079, T = −0.738, P = 0.460) relation is not seen statistically significant, Table 4b represents results obtained from Type-B. In Table 4c, Type-C (Kakao Navi) confirmed a significant positive influence on Perceived Usefulness (β = −0.307, S. E = 0.102, T = −3.026, ***P < 0.001). Type A and Type C support H1, while Type B does not support H1. Most of the results get support from the study conducted by the author, Tom Dieck and Jung (2018).
In support of H2 for Type-A (Kakao Bus) application impact on Perceived Ease of Use is not statistically significant (β = −0.114, S. E = 0.158, T = −0.720, P = 0.471), in case of Type-B (Kakao Taxi) impact on Perceived Easy to use (β = 0.271, S. D = 0.170, T = 1.594, P = 0.111) is not seen statistically significant, and similarly for Type C (Kakao Navi) application impact on Perceived ease of use (β = 0.221, S. E = 0.221, T = −0.996, P = 0.319) is not seen statistically significant. We can conclude that, Type-A, Type-B, Type-C does not support H2. In other words, we can say that in all cases Overseas Residents does not perceive Transportation Application Easy to Use.
To generalize the effect of perceived ease of use on perceived usefulness results obtained the support of H3 for type-A (Kakao Bus) perceived easy to use impact on perceived usefulness is significant (β = 0.736, S. E = 0.023, T = 32.052, ***P < 0.001) results strongly supports this relation. In the case of Type-B (Kakao Taxi) perceived easy to use impact on perceived usefulness is significant. Perceived easy to use is the strongest predictor of perceived usefulness result (β = 0.735, S. D = 0.023, T = 31.646, ***P < 0.001). For Type C (Kakao Navi) perceived ease of use impact on perceived usefulness is also significant (β = 0.730, S. E = 0.023, T = 31.837, ***P < 0.001). In all three cases we can say that overseas residents feel that perceived ease of use plays an important role to support perceived usefulness, H3 accepted. If an application will be easy to use, then it will be more useful for the individuals, results are highly supported by previous research (Shah & Attiq, 2016). To explore the relation of perceived usefulness on travel satisfaction results obtained are not in support of H4. In the case of Type-A (Kakao Bus) application, perceived usefulness impact on travel satisfaction is not statistically significant (β = 0.034, S. E = 0.067, T = 0.516, P = 0.606) relation does not get support from results obtained. In case of Type-B (Kakao Taxi) application, perceived usefulness impact on travel satisfaction is not statistically significant (β = 0.034, S. D = 0.067, T = 0.516, P = 0.606) similarly for Type-C (Kakao Navi) application, perceived usefulness impact on travel satisfaction (β = 0.034, S. D = 0.067, T = 0.516, P = 0.606) is not statistically significant. In all three cases, the relation of perceived usefulness with travel satisfaction is not significant, so we reject H4.
Furthermore, to explore the relation of perceived ease of use on travel satisfaction results obtained are in support of H5. In the case of Type-A (Kakao Bus) application, perceived ease of use impact on travel satisfaction is statistically significant (β = 0.669, S. D = 0.058, T = 11.551, ***P < 0.001), relation get support from results obtained. For Type-B (Kakao Taxi) application, perceived ease of use impact on travel satisfaction is statistically significant (β = 0.669, S. D = 0.058, T = 11.551, ***P < 0.001) so we accept this relation. In the case of Type-C (Kakao Navi) application, perceived ease of use impact on travel satisfaction (β = 0.669, S. D = 0.058, T = 11.551, P = ***P < 0.001) is statistically significant. In all three cases, the relation of perceived ease of use with travel satisfaction is statistically significant, so we accept H5. In other words, we can say that overseas foreigners perceive that perceived ease of use plays an important role in creating travel satisfaction.
Travel satisfaction also has an expected significant effect on life satisfaction (Jun et al., 2012) and significant effect is obtained in support of H6. For Type-A (Kakao Bus) application, travel satisfaction impact on life satisfaction is statistically significant ((β = 0.703, S. D = 0.027, T = 26.269, P = ***P < 0.001). For Type-B (Kakao Taxi) application, travel satisfaction impact on life satisfaction is statistically significant ((β = 0.705, S. D = 0.027, T = 26.062, P = ***P < 0.001). Similarly, Type-C (Kakao Navi) application, travel satisfaction impact on life satisfaction is statistically significant (β = 0.707, S. D = 0.026, T = 26.675, P = ***P < 0.001). We can say that in all three cases travel satisfaction strongly influence life satisfaction, so for overseas residents' travel satisfaction takes much importance to getting satisfied with life, so we accept H6. Travel satisfaction is the strongest predictor of life satisfaction, results get support from research (Bergstad et al., 2011).
Type A (Kakao Bus) and Type-C (Kakao Navi) also have a direct impact on life satisfaction, but for Type-C (Kakao Navi) there is no direct impact on life satisfaction. Results partially support H7.

Results for H8 and H9
The results show that the main effects of Kakao Bus, Kakao Taxi and Kakao Navi were significant (see , Tables 5, 6 and 7). Similarly, to explore the regulatory role of travelers' involvement in perceived usefulness and perceived ease of use, this study conducted a regression analysis in AMOS. Moreover, the interaction effect between traveler's involvement and Kakao Bus application on perceived usefulness and ease of use was not significant, the regulation of traveler's involvement does not play moderation role for Kakao Bus application users; meaning that travelers involvement had a significant effect on usefulness and ease of use in case of Kakao Taxi and Kakao Navi application users but not for Kakao Bus application users. So, we partially accepted H8 and H9 (see, Tables 8, 9 and 10). Interaction between travelers' involvement and Kakao Taxi and Kakao Navi on perceived usefulness and perceived ease of use was significant. The regulation of traveler's involvement plays a moderation role for Kakao Taxi and Kakao Navi application users.

Conclusion
This study was successful in several respects. The new concept of mobile application acceptance behavior was found to have strong results and built significant relationships with satisfaction (Alqahtani & Mohammad, 2015). Our study demonstrates that everyday travel application usage and acceptance affects life satisfaction. The moderation effect of involvement only exists in the Kakao Taxi, Kakao Navi, perceived usefulness and perceived ease of use relationship. Additionally, the moderation effect of involvement does not exist in the Kakao Bus, perceived usefulness and perceived ease of use relationship. In other words, more involvement the more likely that perceived usefulness and perceived ease of use will lead to greater travel satisfaction and life satisfaction; the result gets support from previous research (Chen & Tsai, 2008) the previous study examined personal involvement moderating positive Note: dependent variable: perceived usefulness and perceived ease of use *means P < 0.10 **means P < 0.05 ***means P < 0.001 Note: dependent variable: perceived usefulness and perceived ease of use *means P < 0.10 **means P < 0.05 ***means P < 0.001 effect on the online shopping behavior of consumers while ignored the relation of involvement with travel satisfaction to examine overseas resident's life satisfaction. The findings provide amazing insights into life satisfaction behavior through travel satisfaction obtained from acceptance from mobile transportation application usefulness and easy to use functionality (Bienstock & Royne, 2010). As Kakao Bus and Kakao Navi application users perceive it useful but not easy to use, while easy to use have a direct positive impact in creating travel satisfaction and life satisfaction, usefulness will not influence travel satisfaction until the application will not be easy to use so it is necessary to improve application easy to use the functionality to provide life satisfaction. The question then is how technology acceptance can influence travel satisfaction? It is necessary to focus on perceived easy to use having a direct positive impact on perceived usefulness if users will not consider application easy to use they will not consider it useful, results are supported by previous research (Shah & Attiq, 2016). While users of Kakao Taxi application don't perceive it useful and easy to use, similar to Kakao Bus and Kakao Navi application usefulness will not influence travel satisfaction. We can say that full acceptance of the TAM model plays a major role in creating travel satisfaction to provide life satisfaction. For a human-centered society, it is important to focus on the worth of the TAM model that may have a direct positive effect on overseas residents' travel satisfaction and life satisfaction. The findings are highly relevant for transport planners and IT developers to develop and provide attractive and satisfactory mobile applications for overseas residents. Some factors (seat availability, attitude) during traveling previously investigated were not included in this study (Lunke, 2020;O. Smith, 2017) investigated travel satisfaction but ignored the overseas travel satisfaction and life satisfaction. Instead, more focus is on mobile-based travel application acceptance behavior that is more important for travel application developers. As a result, overseas residents will be often willing to use mobile transportation applications which they will consider easy to use and useful during traveling from one location to another will be highly satisfied with their life in South Korea. This could be solved by providing transportation application demonstrations in different languages such as English or other major languages of overseas residents. If application developers will develop the application with these findings in mind it will result in more satisfied overseas life. As a result, travel satisfaction with the acceptance of travel applications will increase the overall life satisfaction of overseas residents of South Korea. Selected variables are stronger predictors of the overseas resident's life satisfaction in this modern arena. The findings documented can be used to propose a general life satisfaction of overseas residents. Note 1: dependent variable: perceived usefulness and perceived ease of use *means P < 0.10 **means P < 0.05 ***means P < 0.001 Note 2: The combined results of Model 4, Model 5, and Model 6 show results for H8 and H9.

Research implications
This investigation can not only add knowledge to the area of Technology adoption benefits for residents and organizations but also provide important information for overseas regarding what factors they should consider managing their life satisfaction in South Korea. Its result will be very useful for the IT Developers, technology experts, and developers of mobile Applications that are researching the technology adoption behavior and impact on the community.
The population growth rate is decreasing; to increase population some countries attract foreigners as residents because they may be an alternate solution to this problem. The population of the country plays a major role in the development and boost services and manufacturing industries. Without life satisfaction overseas cannot be attracted to stay longer in the country. Future research is needed to address how other variables relate to overseas life satisfaction. Technology adoption situations and intentions have received less attention in life satisfaction theory. As this research was conducted in South Korea, to generalize more results more research is needed by including other geographical areas to understand the relation of overseas life satisfaction with AR technology adoption behavior.
