<abstract>
<p>Augmented reality applications are digital learning innovations that can rapidly improve the learning of college and university students in the virtual setting. Ever since the beginning of the pandemic, on-site teaching has been pushed back to limit the spread of disease. This paper examines the attitudes and subjective and behavioral norms of 100 college students in Thailand toward digital learning innovations accessed through augmented reality applications. The study offers a theoretical model established through the theory of planned behavior (TPB) and uses it to investigate students&#x2019; choices of augmented reality applications as digital learning innovations in their courses. The data were analyzed through structural equation modeling. The findings showed that students&#x2019; acceptance of digital learning innovations through augmented reality applications could be explained through TPB wherever attitudinal and subjective factors showed significant influence; meanwhile, perceived behavioral control did not demonstrate a significant influence on college students. The findings acknowledge the positive effects of augmented reality applications as experienced by college students in Thailand.</p>

<title>Introduction</title>
<p>The worldwide spread of COVID-19 is causing a great amount of devastation across many aspects of our society, especially education. The World Health Organization has confirmed COVID-19 as a global pandemic. The daily news reports highlight the ever-growing list of problems the pandemic is causing around the world, including its economic impacts (<xref ref-type="bibr" rid="B26">Rajmil et al., 2021</xref>). Educational institutions, in particular, are working to reduce the spread of COVID-19 and limit its effects on students&#x2019; lives.</p>
<p>Despite the widespread diffusion of COVID-19, Thailand is comparatively affected by the pandemic (<xref ref-type="bibr" rid="B2">Ali et al., 2021</xref>). In response to the pandemic, Thai colleges and universities imposed a lockdown on face-to-face learning and announced learning and teaching would take place through several virtual channels (<xref ref-type="bibr" rid="B12">Hussain et al., 2022</xref>). However, due to the highly innovative nature of digital learning, numerous students face difficulties with participating in these environments (<xref ref-type="bibr" rid="B37">Tolentino et al., 2022</xref>). Both students and instructors have encountered significant challenges with the practical portions of many courses. For example, engineering and medical students have experienced difficulties with online replacements for lab sessions that previously required in-person instruction (<xref ref-type="bibr" rid="B20">Mseleku, 2020</xref>).</p>
<p>Various authors have emphasized that the pandemic presents an opportunity for institutions to substantially revise their learning systems and, in doing so, re-center themselves and prepare for future change (<xref ref-type="bibr" rid="B29">Saleem et al., 2021</xref>). <xref ref-type="bibr" rid="B18">Maqableh and Alia (2021)</xref> recommended that learning institutions should implement innovative approaches to promote digital learning while eliminating the gaps that learners may encounter in accessing and using these environments. In this regard, information and communication technologies (ICT), especially augmented reality, can play a significant role in enhancing the digital learning experience and allowing students to achieve practical skills through this medium. Augmented reality allows students to deepen their knowledge and understanding of virtual objects <italic>via</italic> collaborative three-dimensional features and enhances users&#x2019; participation <italic>via</italic> smart tools such as tablets (<xref ref-type="bibr" rid="B39">Wang et al., 2021</xref>). Nevertheless, it has been observed that augmented reality applications have been neglected by educational institutions (<xref ref-type="bibr" rid="B25">Psotka, 2022</xref>).</p>
<p>This paper discusses the potential of augmented reality applications to significantly improve college students&#x2019; learning abilities, and abilities to demonstrate practical understanding, in the context of the COVID-19 pandemic. This paper intends to address gaps in knowledge by assessing students&#x2019; attitudes toward digital learning <italic>via</italic> augmented reality applications.</p>
<p>This study used Google Excursions augmented reality applications, built by Google in 2015, as online teaching sources during the pandemic outbreak. These apps are designed to offer a simulated reality <italic>via</italic> smartphones connected with the institution (<xref ref-type="bibr" rid="B24">Pret and Cogan, 2018</xref>; <xref ref-type="bibr" rid="B5">Bourdin et al., 2021</xref>).</p>
<p>The theory of planned behavior (TPB) was used to analyze students&#x2019; attitudes toward digital learning <italic>via</italic> these applications. Various authors have also applied TPB and its components to examine students&#x2019; intentions toward the use of these applications in their learning (<xref ref-type="bibr" rid="B4">Balyk et al., 2021</xref>).</p>
<p>Therefore, three main research questions were proposed:</p>
<disp-quote>
<p>Q1: Do augmented reality applications have any impact on students&#x2019; attitudes toward digital learning?</p>
</disp-quote>
<disp-quote>
<p>Q2: Do augmented reality applications have an impact on students&#x2019; subjective norms regarding digital learning?</p>
</disp-quote>
<disp-quote>
<p>Q3: Do augmented reality applications have an impact on students&#x2019; perceived behavioral control toward digital learning?</p>
</disp-quote>
<p>The current paper is innovative in that the theory of planned behavior has never before been used to assess attitudes toward augmented reality applications in Thailand. The results derived from this study add new insights to the literature on the challenges of conducting the practical portions of college courses within in the online domain.</p>

<title>Augmented reality applications</title>
<p>In the current period of easily accessible advanced technology, the educational structure has become more varied. Novel tools, with their ability to facilitate interaction among learners and instructors, are now used in digital learning systems as empirical cognitive devices (<xref ref-type="bibr" rid="B33">Sudirman et al., 2020</xref>). Moreover, visualization delivered <italic>via</italic> intelligent devices, e.g., tablets, can perform important functions in many different situations and can be of use in overcoming the limitations of digital learning. Research has examined the influence of augmented reality applications on students&#x2019; learning intentions (<xref ref-type="bibr" rid="B38">Wang et al., 2017</xref>) and has found that these applications can improve students&#x2019; educational accomplishments and learning abilities as compared to conventional learning methods for all types of classes. For example, <xref ref-type="bibr" rid="B32">Shin (2018)</xref> claimed that several learners could not better understand their syllabus through traditional online systems. Thus, augmented reality applications play a significant role in constructing a strong link between students and instructors <italic>via</italic> 3D based applications for online learning.</p>
<p><xref ref-type="bibr" rid="B23">Ozdimer et al. (2018)</xref> define augmented reality applications as those that create a three-dimensional reality that can present the digital world as a physical phenomenon. Collaborative technologies, i.e., augmented reality applications, enable students by offering solutions to the challenges they face. With these applications, students can enter the virtual setting, actively contribute, and relate to virtual things in the real world, increasing their three-dimensional abilities (<xref ref-type="bibr" rid="B39">Wang et al., 2021</xref>).</p>
</sec>
<sec id="S2.SS2">
<title>The hedonic value of augmented reality applications</title>
<p>Hedonic value, in simple terms, refers to the value perceived through real-time enjoyment and fun. Academic staff can ensure student satisfaction by providing real-time experiences through applications with hedonic value.</p>
<p>The hedonic value of an application involves providing digital experiences accompanied by real sensations that recall doing things in a physical setting. Doing lab experiments online, for example, can be just as enjoyable as digitally trying on makeup (<xref ref-type="bibr" rid="B27">Rab et al., 2013</xref>). The hedonic value itself allows these applications to provide real-time understanding to their users, improving playfulness (<xref ref-type="bibr" rid="B43">Zhong et al., 2021</xref>). <xref ref-type="bibr" rid="B40">Wetzels et al. (2009)</xref> found that hedonic value is a highly significant part of augmented reality applications, triggering learners&#x2019; rational and expressive approaches in a way that directly connects them with practical effects. Likewise, <xref ref-type="bibr" rid="B14">Iwanaga et al. (2021)</xref> examined students&#x2019; logical- and emotional-based learning and understanding as significant factors in their intention to benefit from augmented reality&#x2013;based education. Hedonic values promote real knowledge and the inspiration to gain it, including elements that affect students&#x2019; commitment to the course (<xref ref-type="bibr" rid="B11">Haverila and Haverila, 2021</xref>). As an illustration from the literature, <xref ref-type="bibr" rid="B3">Arnold and Reynolds (2003)</xref> argued that hedonic value defines users&#x2019; perceived behavioral control, which in turn influences their attitude and intention. It also improves the effectiveness of the course and maximizes students&#x2019; understanding of it, thus defining the students&#x2019; point of choice, such methods have been investigated with augmented reality systems by past author as well (<xref ref-type="bibr" rid="B35">Teo, 2011</xref>). This innovation looks at augmented reality applications offers a distinctive understanding level (<xref ref-type="bibr" rid="B7">Cheng, 2020</xref>). At the same time, a previous study reported that it offers stimulation, self-representation, pleasure, and hedonic practices (<xref ref-type="bibr" rid="B9">Chu et al., 2018</xref>). The hedonic aspect of augmented reality significantly influences students&#x2019; behavioral intentions and attitudes toward digital learning (<xref ref-type="bibr" rid="B16">Khodadadi et al., 2020</xref>).</p>
</sec>
<sec id="S2.SS3">
<title>The utilitarian side of augmented reality applications</title>
<p>From a utilitarian perspective, augmented reality applications offer a logical and useful interaction with specific objects that can potentially influence the user&#x2019;s behavioral intentions (<xref ref-type="bibr" rid="B21">Novak et al., 2013</xref>). These applications hold strong potential as innovations in current or new digital learning systems (<xref ref-type="bibr" rid="B13">Hyde, 2019</xref>). It has been established that the utilitarian aspect can enhance objects&#x2019; visibility and increase their recognition in a real-time environment, thus contributing to an optimistic attitude among users and their perceived intention to use the application (<xref ref-type="bibr" rid="B22">Novak et al., 2000</xref>). They can also improve the physical appearance of online courses, further engaging and inspiring students with regard to digital learning (<xref ref-type="bibr" rid="B41">Yimaz, 2016</xref>).</p>
<p>The pandemic has caused educational institutions around the world to shift to a digital-based education system. The utilitarian aspect of augmented reality increases the practicality of digital courses (<xref ref-type="bibr" rid="B13">Hyde, 2019</xref>) and therefore affects students&#x2019; logical insights toward digital learning systems (<xref ref-type="bibr" rid="B19">Mi et al., 2020</xref>).</p>
<p>Numerous authors have analyzed the two aspects of augmented reality applications, i.e., the hedonic and the utilitarian, on users&#x2019; behavioral intentions (<xref ref-type="bibr" rid="B34">Taipour et al., 2021</xref>).</p>
<p>Consequently, this study contends that the impact of augmented reality applications on students&#x2019; behavioral intentions toward digital learning systems during the pandemic remains underexplored. The following hypotheses were therefore proposed, positing augmented reality applications as a single independent variable and students&#x2019; attitudes, subjective norms, and perceived behavioral control as three separate dependent variables. Each hypothesis is linked, respectively, to the corresponding research question posed in Section 1 above.</p>
<disp-quote>
<p>H1: Augmented reality applications have a positive impact on students&#x2019; attitudes toward digital learning.</p>
</disp-quote>
<disp-quote>
<p>H2: Augmented reality applications have a positive impact on students&#x2019; subjective norms toward digital learning.</p>
</disp-quote>
<disp-quote>
<p>H3: Augmented reality applications have a positive impact on students&#x2019; perceived behavioral control with regard to digital learning.</p>

<title>Methodology</title>
<p>Data were collected from 100 college students in Thailand <italic>via</italic> convenience sampling. The minimum sample size was calculated through G&#x002A;Power software, having three predictors with an effect size of 0.15 and a power of 0.95, with two tails that came to the minimum sample size of 89 (<xref ref-type="bibr" rid="B9">Faul et al., 2009</xref>). The sample size of this study is therefore above the minimum requirement. Students were contacted through a Facebook group set up by teachers to connect for assignments and lecture updates. A virtual survey form was distributed among the group members and voluntary contributions to the research were sought. Participants were instructed to install the Google Expeditions application on their tablets to experience online learning through augmented reality. A value check was employed in the form of an online survey that posed several appropriate questions about participants&#x2019; familiarity with Google Expeditions and asked them to register their responses <italic>via</italic> a Likert scale. The question items were adapted from previous literature. The hedonic and utilitarian aspects were adapted from <xref ref-type="bibr" rid="B15">Khare et al. (2010)</xref> and <xref ref-type="bibr" rid="B31">Scholz and Duffy (2018)</xref>. The TPB constructs, i.e., attitude, subjective norms, and perceived behavior control toward digital learning, were adapted from <xref ref-type="bibr" rid="B16">Khodadadi et al. (2020)</xref>.</p>
<p>The data were analyzed through PLS(SEM) because of its potential to bootstrap the results into a larger sample size (<xref ref-type="bibr" rid="B17">Krishnan et al., 2011</xref>).</p>

<p>From <xref ref-type="table" rid="T2">Table 2</xref>, it can be seen that the augmented reality applications have an &#x03B1; of 0.755, a CR of 0.815, and an AVE of 0.656. The hedonic aspect has an &#x03B1; of 0.777, a CR of 0.965, and an AVE of 0.653. The subjective norm has an &#x03B1; of 0.762, a CR of 0.863, and an AVE of 0.679. Lastly, the perceived behavioral control has an &#x03B1; of 0.782, a CR of 0.780, and an AVE of 0.719. This means that the reliability standards of the adopted questionnaire have been satisfied and that it meets the standards of PLS for hypothesis testing.</p>
<p>To confirm the validity of the research questionnaire, it has been recommended to examine the diagonal and non-diagonal values in the correlational table of results; the non-diagonal values should be lower than the diagonal ones, or, put another way, the diagonal values should be higher than the non-diagonal values (<xref ref-type="bibr" rid="B30">Sarstedt et al., 2014</xref>). The validity aspects for the present study are reported in <xref ref-type="table" rid="T3">Table 3</xref>. The diagonal value for the attitude is 0.936; for the augmented application, 0.990; for the perceived behavioral control, 0.763; and for the subjective norm, 0.71. As all of these values are higher than the non-diagonal values, we can conclude that the adopted questionnaire was valid and reliable.</p>

<p>The results of the hypothesis testing are presented in <xref ref-type="table" rid="T4">Table 4</xref>. This study proposed three main research questions linked with three hypotheses, respectively. To answer these research questions, there was a strong need to run bootstrapping tests on the collected data. As can be seen in <xref ref-type="table" rid="T4">Table 4</xref>, attitudes toward digital learning were tested within the context of augmented reality applications, and the <italic>t</italic>-value came out to 1.96 with a beta value of 0.725. Thus, hypothesis 1 has been confirmed; as the results demonstrate, augmented reality applications can play a positive role in changing students&#x2019; attitudes toward digital learning. Similarly, the results support research question 2 and hypothesis 2, with a beta value of 0.729 and <italic>t</italic>-value of 1.99. We can therefore conclude that augmented reality applications play a positive role in changing students&#x2019; subjective norms toward digital learning. However, the results did not support research question and hypothesis 3, because the <italic>t</italic>-value was lower than 1.96 and the beta value was also low. However, it was interesting to see that the existing relationship was positive, but at a very low intensity.</p>

<title>Discussion</title>
<p>This study intended to examine the characteristics of augmented reality applications in digital learning systems in Thailand during the pandemic by employing the theory of planned behavior. The findings showed that college students&#x2019; attitudes and subjective norms influence digital learning through augmented reality applications. The beta value for attitude came out to 0.725 with a <italic>t</italic>-value of 1.96, which means that there is a positive association between augmented reality applications and attitudes toward digital learning. This supports the first hypothesis and confirms the findings of previous authors (<xref ref-type="bibr" rid="B36">Chu et al., 2018</xref>; <xref ref-type="bibr" rid="B6">Chen, 2019</xref>). Similarly, the beta value for the second hypothesis comes out to 0.729, with a significant <italic>t</italic>-value of 1.99. The findings connected to this hypothesis are similar to the results of previous authors (<xref ref-type="bibr" rid="B22">Novak et al., 2000</xref>). However, perceived behavior control demonstrated a non-significant impact on digital learning through augmented reality applications, because the beta value (0.012) was lower, with an insignificant <italic>t</italic>-value of 1.92. A previous study by <xref ref-type="bibr" rid="B41">Yimaz (2016)</xref> had similar results for perceived behavioral control.</p>
<p>The integration of augmented reality applications into digital learning systems must be considered from a rational perspective. College students&#x2019; use of augmented reality applications improves their knowledge, as these applications offer a three-dimensional presentation of the course. They also increase communication and improve outcomes, including maximizing students&#x2019; knowledge. The present moment is thus an ideal time to entertain the idea of introducing this digital education method. Previous studies by <xref ref-type="bibr" rid="B1">Ak&#x00E7;ay&#x0131;r et al. (2016)</xref> and <xref ref-type="bibr" rid="B6">Chen (2019)</xref> highlighted the potential of digital learning approaches for improving the delivery of education. <xref ref-type="bibr" rid="B8">Cheon et al. (2012)</xref> suggested that augmented reality applications can improve the way students work with the course, as well as boost their confidence levels. However, these applications may not influence the students&#x2019; perceived control.</p>
<p>As <xref ref-type="bibr" rid="B42">Yoo et al. (2021)</xref> discuss, most educational institutions have used conventional technologies (e.g., Zoom, Google Classroom) to operate online courses since the pandemic was declared. Classes held using these technologies most likely do not hold students&#x2019; attention. Most people who matter to students are against the use of augmented software for digital learning. Further investigation <italic>via</italic> qualitative analyses is needed to better understand this phenomenon.</p>
<p>The significant capabilities offered by these applications improve students&#x2019; level of knowledge and reduce the psychological challenges posed by digital learning. Several digital learning networks have been launched since the start of the pandemic. As <xref ref-type="bibr" rid="B28">Saidin et al. (2015)</xref> stated, augmented reality applications represent the core principles of coursework that effectively help students perform their practical work. Augmented reality applications, and the collaborative capabilities they offer, add a distinctive element: the ability to bring the presence of simulated objects into the real world, with significant effects on users&#x2019; recognition and composition.</p>
<p>Moreover, research on augmented reality applications in the context of an ASEAN country could be quite valuable for the relevant literature. Thailand is currently considered an emerging country in the context of the use of augmented reality applications in online education systems. This study addresses the challenges of providing a realistic learning experience for students, which were quite significant during the height of the pandemic. The augmented reality applications used for this study were Quiver, Element 4D, and Domino World AR, as the trial version to test their impact on students&#x2019; learning experiences. Each of these applications was designed to bring life and physical reality to the virtual classroom setting. Additionally, they were found to be more engaging and made difficult subject matter easier, as per the findings of the research study.</p>
<p>More precisely: Quiver is used more for subjects in the natural sciences, as it allows the use of interactive 4D images. Similarly, Element 4D facilitates conducting practical experiments in a virtual setting. Domino World AR allows the instructor to create the course in the virtual setting by adding interesting props to turn a serious lecture into an interesting one.</p>
<p>Lastly, three research questions were raised in the introduction to the present study. To answer those questions: the results of this study found that, in the case of students in Thailand, augmented reality applications do have a positive effect on their attitudes and subjective norms toward digital learning, but not on their perceived behavioral control.</p>

<title>Conclusion</title>
<p>This study explores the role of students&#x2019; attitudes, subjective norms, and perceived behavioral control in adopting augmented reality applications for digital learning. The findings have shown that students play a strong role in digital learning through these applications. Lecture delivery through an augmented application boosts students&#x2019; confidence and influences their attitudes and subjective norms. As a result of the pandemic, many learners face difficulties in joining online courses through traditional resources. Moreover, for higher education institutions and students in both affluent and developing nations, digital learning remains both a cultural problem and a tough technical dilemma. This research is limited to data sampling from one country. The results are therefore not generalizable to all levels of educational institutions or to all students. As a result, paths are open for future qualitative and quantitative studies, or both, to investigate factors that restrict and encourage the use of augmented reality applications in the delivery of education at various levels and across geographic contexts.</p>
<sec id="S6.SS1">
<title>Limitations and future research potential</title>
<p>Due to the lack of sufficient time and resources, only data from Thailand were available. The generalizability of this study to other country contexts is therefore limited. Other researchers may want to use this study as an example for testing augmented reality applications in the context of other countries. Future investigators could also test other applications apart from those used in this study.</p>

<sec id="S6.SS2">
<title>Contribution to theory and practice</title>
<p>This study contributed to the theory of planned behavior in the context of the challenge of converting virtual learning into a real experience by extending its use <italic>via</italic> augmented reality applications. In practice, this study, and its findings of proof of the effectiveness of these applications among students, can serve as an example and a source of motivation for educational researchers and institutions to move from the use of conventional digital learning applications to augmented reality applications.</p>
