The Impact of Perceived Interactivity and Intrinsic Value on Users’ Continuance Intention in Using Mobile Augmented Reality Virtual Shoe-Try-On Function

: In response to the rapid growth of mobile Internet, online retailers have created better shopping experiences through new technologies. These shopping experiences are the product of the new interaction methods created by new technologies and the intrinsic value of these technologies. To achieve a better understanding of how new technologies improve consumers’ intention to use them continuously, this study established a theoretical model of how consumers’ perceived interactivity affects intrinsic value, which then affects attitudes, and ultimately contributes to the theoretical model. Within the perceived interactivity construct, there is perceived control, personalization and responsiveness, and as part of the intrinsic value construct there is playfulness and aesthetics. The results demonstrate that intrinsic value and perceived interactivity play important roles in predicting consumers’ attitudes and continuance intention to use new technologies applied to mobile e-commerce, but do not include perceived control in perceived interactivity. To highlight the results of this study, relevant enterprises or practitioners may use the ﬁndings to design or improve the features of existing mobile apps to provide better services and experiences to consumers based on their internal perceptions.


Background
Smartphones and other mobile technologies have become an integral part of modern consumption and life [1], forcing a transformation of the global business environment, especially the global retail industry [2]. As technology advances, Augmented Reality (AR) technologies have become more advanced and widespread, enhancing the functionality and user experience of smartphones. AR is being implemented in many industries including education, engineering, healthcare, military, real estate, retail, and the game industry. The retail and the game industry are two of the earliest industries to extensively utilize AR technology [3].
Successful implementation of AR has drawn the attention of Chinese e-commerce companies. Since 2016, major e-commerce platforms have announced or released plans and progress associated with Augmented Reality (AR/VR) [4]. Meanwhile, the Chinese government's Opinions on Promoting Innovation and Transformation of Physical Retailing supports the integration, innovation, and transformation of online and offline shopping [5]. Despite the improvement in purchasing power in the huge Chinese market, many consumers in secondand third-tier cities have difficulty shopping in physical stores for the latest products. Moreover, due to repeated epidemic waves in the last two years [6], online shopping has become increasingly popular. In order to compensate for the insufficiency of the online shopping experience, e-commerce companies are utilizing AR technology to address the problems of online shopping that are difficult to experience directly, such as the inability to try on clothing and shoes [4]. Moreover, due to the novelty and sense of the AR technology, many consumers are attracted to it, for example to the virtual shoe test function on the POIZON APP. Therefore, after the initial excitement, e-commerce companies should take the time to explore the inner relationship between AR functions and consumers, while at the same time shifting their focus to the perceivable value of consumers' behavior to increase service and attract consumers better.
Therefore, this study takes POIZON APP as the research carrier and takes consumers who have used POIZON APP virtual shoes as the research object to explore how perceived interactivity and intrinsic value affect users' continuation of the use of mobile augmented reality (MAR) of the virtual shoe-try-on function and their correlations. Then improvement suggestions are proposed to the government, industry, consumers, and other relevant units for reference.

Significance of Research
AR is a medium that uses machine vision and 3D graphics to cover virtual elements in the physical environment [7]. It is capable of providing a different interactive environment than the one established by the previous virtual environment. With the background of a real-life scene, it can help consumers perform various functions and behaviors more directly. Meanwhile, the interaction between people and their phones and the outside world is also enhanced. Due to the rapid development of AR technology, it is also highly valued by practitioners and developers. It is considered vital to address the issue of how to attract consumers more effectively and develop AR functions and technologies that consumers prefer [8]. Recent studies explore a range of topics, including brand AR interaction [9], AR's role in driving consumer decision-making [10], AR's impact on reducing the return rate [11], and AR applications on shopping guides [12]. Research indicates that AR is capable of filling the information gap between online shopping consumers and products [13], and it has a significant positive effect on online shopping.
In comparison to ordinary AR, MAR has a low cost, a high degree of flexibility, and a high level of interactivity, and has been determined as the preferred platform for product information and interactive presentations [14]. As one of the fastest-growing research areas in augmented reality [15], numerous studies have focused on the interaction between mobile apps that utilize MAR technology and users [16][17][18][19]. A MAR APP enables consumers to visualize and evaluate products or services instantly through their smart devices [19]. As part of this research carrier, it is also the field and technology involved in the POIZON APP.
According to statistics, approximately 25% of MAR applications are not used after the initial download [2], so the continuance intention to use MAR requires attention. Lo et al. observed consumers' purchase intentions following MAR interactions [20]. Tsai and Hung investigated the influence of community identity and interpersonal relationships on continuance intention to use [21]. Hung et al. studied the impact of perceived mobility, perceived enjoyment, and perceived connectivity on consumer perception [22]. Consequently, this study fills the research gap by evaluating consumers' continuance intention to use MAR from two perspectives: perceived interactivity and intrinsic value.

The Suitability of MAR for Virtual Shoe-Try-On Function
The virtual shoe-try-on function is enabled by augmented reality technology, which uses foot characterizations to detect the characteristics of the individual's feet to track and display the motion trajectory of virtual shoes [23]. However, in the case of non-mobile online stores, the limitations of camera equipment should be considered. In this regard, laptops and desktops with fixed lenses are ineffective at capturing real-time images of the user's foot and demonstrating the try-on effect. When designing the lenses of such devices, there is not much consideration given to the needs of the user's feet. Despite the availability of movable cameras in some computers, the users are still required to look up at the screen to observe the AR images. Thus, the AR shoe-try-on function is highly dependent on the angle of shooting and the ambient light, making it incompatible with online stores that are not mobile. However, through mobile devices, such as mobile phones, MAR provides a solution to the simultaneous shooting and display problem and the feasibility of virtual shoe-try-on function in practice. In addition, this technology is capable of improving the user experience [24]. Additionally, MAR enables users to virtually try on shoes in a variety of settings. Users are provided with practical information to enhance their real-time visualization of the world [25]. MAR encourages creativity and spontaneity in users [26,27]. It is crucial for platforms or brands that provide virtual shoetry-on functions to explore these features actively. A virtual shoe-try-on function would benefit from the implementation of MAR. In the context of MAR, it is necessary to discuss the user's perceptions and preferences regarding virtual shoe-try-on functions. Hence, this study is different from the virtual trial research conducted in non-mobile online stores, such as online furniture stores and online cosmetic stores [28]. Since there is currently little discussion on consumers' experience of virtual shoe-try-on functions under MAR conditions, this research provides a theoretical basis for future marketing research in this area, which has academic and commercial relevance.

Continuing Intention and Attitude
Continuing intention refers to consumer behavior that is affected by re-use or experience [29], and is one of the factors used to assess a product or service's success [30]. To put it another way, the longer customers continue to use the product after it has lost its freshness and heat, the greater chance that the product will be successful [31]. The relationship between consumers' intention and attitude has been discussed in many models, including TRA [32], TPB [33,34] and TAM [35]. Attitudes are viewed as aspects of a person's internal experiences that can affect consumer intentions, making them one of the most important factors affecting consumer intentions. Previous studies on AR mobile games have shown that attitude affects behavioral intention [36].

Perceived Interactivity
Interactivity is defined as "technology that operates via telecommunication channels (e.g., telephone) to provide person-to-person or machine-to-machine interaction that imitates interpersonal communication (e.g., electronic banking transactions)" [37]. In contrast, with the development of digital communication, the concept of interactivity has become diverse, including interactive processes [38], technical products [39], user perception [40], etc. From the perspective of perception, perceived interactivity is defined as "users perceiving their experience via the imitation of interpersonal interaction and the extent of their perception as they interact socially with others" [41].
In terms of perceived interactivity, it is a concept that is still developing, so it may have different components in varying circumstances [3], but generally, it consists of the following: control, responsiveness, real-time interactions, connectedness, personalization, and playfulness. Each represents a different aspect of perceived interactivity: control refers to the perception of consumers as being in control of the information and content of tech-products; responsiveness refers to the degree or speed with which tech-products respond to consumers; real-time interaction refers to the speed of occurrence or response when tech-products are used for communication; connectedness refers to the possibility of sharing relevant experiences with other consumers; personalization refers to the capacity of tech-products to adapt to the unique needs of consumers; playfulness refers to the entertainment value that tech-products provide [42][43][44][45][46].
Despite the presence of many aspects of perceived interactivity, different researchers explore the subject from different angles as a result of various research topics. Due to the fact that the virtual shoe-try-on function in POIZON APP involved in this study enables individuals to complete shoe-try-on function by using MAR technology through their smartphones, real-time interactions and connectedness are not relevant to the study. In terms of playfulness, it goes is in accordance with the research of Kang et al. According to this study, playfulness refers to "perceived playfulness", i.e., the enjoyment and escape consumers perceive [47], as opposed to the playfulness the tech-products themselves exists as a substructure construct of perceived interactivity [42]. Therefore, the perceived playfulness is also excluded from the perceived interactivity, and Section 2.3 provides further explanation. In summary, the perceived interactivity in this study is examined in three dimensions: control, responsiveness, and personalization.

Intrinsic Value
Because attitudes are perceived as the intrinsic experiences of individuals that influence consumer intentions, it is essential to understand what type of "intrinsic" influences attitudes. In the context of this study, control, responsiveness, and personalization will ultimately affect attitudes and intentions. According to Section 2.2, control, responsiveness and personalization are more likely to form various characteristics of technological products in interaction [48], so they need to be converted into consumers' intrinsic attitudes and intentions by some unknown factors. The unknown factor has been interpreted differently by various scholars due to issues, such as mental imagery [3], efficiency, effectiveness, enjoyment, and trust [46]. This study interprets this "intrinsic" as "intrinsic value" to explain the factors that affect consumer attitudes. Perceived interactivity intrinsic value, which in turn influences attitude and then intention.
The purpose of the MAR virtual shoe-try-on function is to facilitate the mobile online shopping experience. Consumer experiences are also of value, which is derived from the interaction between direct use or remote appreciation of commodities and services [49]. Several studies have shown that experience value offers external and internal benefits [50][51][52]. Viewed from the perspective of the retail industry, the external benefits normally arise from the primarily utilitarian shopping process [51], whereas the intrinsic value comes from the appreciation of the experience [53]. In Holbrook et al.'s research, experience value is categorized into four quadrants, with intrinsic and extrinsic value sources on one axis and active and passive values on the other [53]. However, in the study by Mathwick et al., the intrinsic value is marked as playfulness and aesthetics [49], which this study uses as a basis for future investigation.
Nowadays, APPs have advanced significantly in terms of their functionality, ease of use, security, privacy, etc. [54][55][56], and there are very few instances of poor functionality or fatal bugs. Therefore, it is necessary to consider competitiveness from the perspective of attracting and retaining consumers. Kumar et al. have proposed that it is possible to increase the appeal of APP from an aesthetic perspective [57]; aesthetics play a crucial role in online shopping as well [58]. Consumers will be more likely to be attracted to a mobile application if its interface, process, color, and experience are more aesthetic [59]. It has also been demonstrated that aesthetics play a significant role in human-computer interaction [60]. Therefore, the current study believes that the degree of aesthetics perceived by consumers is one of the factors contributing to the perception of intrinsic value by consumers.
From the perspective of value-conscious hedonism, if you want users to enjoy an application, you have to make the user experience engaging [61]. The playfulness in this study refers to the subjective evaluation of the consumer's experience of the AR virtual shoe-try-on function from an emotional perspective. As an intrinsic motivation, playfulness is considered one of the significant factors that determine whether a consumer will accept a technological system and continue to use it. If consumers perceive more interest in the interaction, the intention of use will be higher [62]. As a result of the unique attributes of augmented reality, it may facilitate the enjoyment of customer shopping experiences through applications, and ultimately increase consumer participation by providing a more interactive and interesting shopping experience and bringing the in-store experience to home [3].

Research Structure and Research Hypothesis
As stated above, this study confirms the importance of perceived interactivity and intrinsic value. Based on this study, the interactivity of consumers using the AR virtual shoetry-on function affects the intrinsic value perceived by them, which in turn impacts their attitude toward and intent to use the product in the future. Accordingly, this study develops an architecture model within which perceived interactivity (perceived personalization, perceived control and perceived responsiveness) affects intrinsic value (aesthetics and perceived playfulness), which in turn affects the research structure of the attitudes and continuance intention to use (Figure 1), and makes the following assumptions: Hypothesis 1 (H1). The attitudes of consumers toward the AR virtual shoe-try-on function will positively affect the continuance intention to use.

Hypothesis 2 (H2).
The aesthetics of the AR virtual shoe-try-on function perceived by consumers will have a positive impact on their attitudes.

Hypothesis 3 (H3).
The perceived playfulness of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward it.

Hypothesis 4 (H4).
The perceived control of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived aesthetics.

Hypothesis 5 (H5).
The perceived responsiveness of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived aesthetics.
Hypothesis 6 (H6). The perceived personalization of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived aesthetics.

Hypothesis 7 (H7).
The perceived control of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived playfulness.

Research Object
The purpose of this study is to investigate the factors that influence consumers' continuous intentions to use AR virtual shoe-try-on function. For the purpose of exploring the relationship between various factors, this study utilized structural equation modeling (SEM) for data analysis. Due to the POZION APP's popularity among the young generation, it is primarily enjoyed by young adults (college students), who are interested in sneakers and trendy shoes. Therefore, in this study, the respondents to the questionnaire are college students who have used the POZION APP and the AR virtual shoe-try-on function more than twice. Multiple-use is chosen as the survey object due to the fact that multiple-use suggests the intention to use the service continuously, which meets the requirements of the research object.

The Process of Using Virtual Shoe-Try-On Function
The procedure for using the POZION APP's virtual shoe-try-on function is as follows: 1. Click the search bar on the shopping interface of the POIZON APP to search for the shoes (It should be noted that this feature does not include all of the shoes for sale, and their database is still in development); 2. Click the AR try button on the detail interface of the shoe you wish to try on; 3. On the try-on interface, the AR virtual shoe function can be implemented by aiming at the user's foot with the camera of the mobile phone, which will allow the virtual shoes to adjust to the user's movements or changes in angle ( Figure 2).

Questionnaire Design
The questionnaire items were designed based on the theme and related literature in this study. Table 1 presents the reference sources of latent variable, coding, item and source information.

Data Collection
The study was conducted through an online questionnaire from September to October 2021. In addition to basic personal information, the Likert 7-point scale was used, ranging from 1 representing strongly disagree to 7 representing strongly agree. All those who completed the questionnaire clicked on the link of the questionnaire to view the survey description. Participants answer the research questions voluntarily and could withdraw at any time. In this regard, all participants agreed to fill out the questionnaire voluntarily and were fully informed.
Ultimately, 311 samples were collected in this study and after removing invalid samples (logical errors or too many similar options), the remaining samples were 286, and the recycling efficiency was 91.96%. Accordingly, there were 21 questionnaire questions in this study, and 286 valid samples met Jackson's standard that the ratio of estimated parameters to the number of samples should not be less than 1:10 [66]. Therefore, subsequent data analysis was carried out based on this. Statistical analyses were performed on the data collected from valid questionnaires. Table 2 presents the statistical results.

Reliability Analysis
Cronbach's α coefficient and total correlation coefficient of correction items (CITC) were used to validate the questionnaire. According to Table 3, the CITC of all constructs is higher than 0.6, and the reliability coefficient does not improve significantly after the deletion of questions. Furthermore, Cronbach's coefficient of reliability is higher than 0.7. Thus, the questionnaire and scale used in this study demonstrate a high degree of internal consistency, which allows for further analysis.

Exploratory Factor Analysis
SPSS 26.0 was used in this study for exploratory factor analysis to verify the single construct of each construct, and the results are shown in Table 4. The principal component analysis was used to identify new factors with eigenvalues greater than 1. Results indicate that the KMO values of all constructs are greater than 0.70, and the Bartlett sphericity test significance is less than 0.05, indicating that exploratory factor analysis would be appropriate [67,68]. The items belonging to each construct are involved in the extraction of new factors, and only one factor with an eigenvalue greater than 1 can be recovered [69], indicating a good single construct [70].

Confirmatory Factor Analysis
AMOS V22.0 was used to analyze the structural equation model. AMOS has been used in several studies, which has proven to be reliable structural equation modeling software. According to Anderson and Gerbing, data analysis was divided into two stages [71]. The first stage is the Measurement Model, which employs the maximum likelihood estimation method and estimates the following parameters: factor load, reliability, convergence validity, and discriminant validity. This is done according to studies of convergence validity by Hair et al. [72], Nunnally and Bernstein [73] and Fornell and Larcker [74], and studies of standardized factor loading by Chin [75] and Hooper et al. [76], as shown in Table 5 below. The standardized factor load in this study is higher than 0.6, the reliability of the research construct composition is higher than 0.7, and the average variance extraction (AVE) is higher than 0.5, thus indicating that this construct has good convergence validity [72].  Fornell and Larcker [74] are adopted for discriminant validity. If the square root of the AVE of each construct is greater than the correlation coefficient between the constructs, the model is discriminant valid. According to the results, all diagonals in this study have greater values than those outside the diagonals, indicating that each of the constructs in this study has good discriminant validity (as shown in Table 6).

Model Test
A selection of indexes (MLχ 2 , DF, χ 2 /DF, RMSEA, SRMR, TLI, CFI, NFI, IFI) has been used as a parameterized measure for evaluating the fitting degree of the structural model based on studies performed by Jackson et al. [77], Kline [78], Schumacker [79], and Hu and Bentler [80]. As shown in Table 7, the study construct was measured based on the study hypothesis and model. In addition, all the standard model fit degree evaluation indicators met the independent level and combination rule of the recommended fit, which proved that the structural model had a good fit degree, and the theoretical framework of the study hypothesis made sense in light of the survey data.  This study tested the effect of the path in the model. Table 8 and Figure 3 below show that, except for the two paths from PC to AE and PPF, all the other paths presented significant significance, illustrating the model constructed in this study. It explains some of the factors influencing consumers' continuance intention to use AR virtual shoe-try-on function.

Discussions
Several key findings are derived from the validation of the structural equation model and various verification results, which are discussed in the following paragraphs: H1 is valid, indicating that consumers' attitudes towards AR virtual shoe-try-on function have a positive impact on their intention for continued usage, and the path coefficient is the highest. In other words, attitude is the most important factor in determining whether consumers continue to use the AR virtual shoe trying function. Numerous studies confirm the influence of attitude on intentions [81][82][83]. In addition, it emphasizes that in order to make consumers have a stronger intention of continuous use, it is necessary to change their attitude in a positive direction. According to the findings of this study, such internal transformation is presupposed to be perceived interactivity and internal factors, which will be discussed in detail below.
H2 is valid, indicating that consumers' perception of beauty in AR virtual shoe trying has a positive impact on their attitude. The path coefficient is second only to H1, which indicates that consumers are very concerned about aesthetics. H3 is valid, indicating that consumers' perceived playfulness would positively affect their attitude towards AR virtual shoe-try-on functions. In product design and marketing, aesthetics play an important role [84], as evidenced by the APP product interface [57], the process experience, visual aesthetics [85], colors, etc. It is likely that consumers will perceive a higher degree of aesthetics if the above aspects are more prominent, reflecting that they will have a positive attitude and intent. From the perspective of AR virtual shoe-try-on function with prominent interactive attributes, aesthetics tend to have a hedonic value [86]. According to our discussion in Chapter 2, the enjoyment value perceived by consumers is primarily based on "perceived playfulness" [61], which is influenced by a consumer's curiosity, interaction and perception of AR virtual shoe-try-on function [87]. Studies have shown that the level of perceived playfulness will directly affect consumers' participation [88] and happiness [89]. From the perspective of intrinsic value comprised of intuitive feeling and inner sense of perceived playfulness derived from aesthetics, this explains the critical factor that affects consumers' attitudes and intentions towards AR virtual shoe-try-on function.
H6 is valid, indicating that consumers' perceived personalization will positively influence their attitudes toward the perceived aesthetics of AR virtual shoe trying. H9 is valid, indicating that the perceived personalization of consumers in AR virtual shoe-tryon function will positively influence their attitudes toward the perceived playfulness. Furthermore, the validity of H6 and H9 means that the perceived personalization of consumers has a positive impact on consumers' perceptions of the intrinsic value of the AR virtual

H6 is valid, indicating that consumers' perceived personalization will positively influence their attitudes toward the perceived aesthetics of AR virtual shoe trying. H9 is valid, indicating that the perceived personalization of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived playfulness. Furthermore, the validity of H6 and H9 means that the perceived personalization of consumers has a positive impact on consumers' perceptions of the intrinsic value of the AR virtual shoe-try-on function. Consistent with our hypothesis, the AR virtual shoe-try-on function enables consumers to visualize products in relevant scenes [90] and enhance their perceived personalization in real-life settings [91]. In the meantime, perceived personalization more significant greater impact on consumers' perceived playfulness. Both of these characteristics tend to be perceived attributes of personal preferences and it has been found that the more personalized settings and processes there are, the more playfulness consumers will experience. Perceived playfulness, of course, is not the only factor that is affected by perceived personalization, which also has a significant impact on the process of using and interface loading of the entire AR virtual shoe-try-on function. Customers' individual APP usage habits and the degree of optimization also influence their experience, which, in turn, affects their attitudes and intentions.
As H4 is invalid, it indicates that consumers' perceived control over the AR virtual shoe-try-on function would not affect their perception of its aesthetics. H7 is invalid, indicating that consumers' perceived control will not affect their perceived playfulness of AR virtual shoe-try-on function. As can be seen, consumers' perceived control over AR virtual shoe-try-on function does not affect the two sub-factors of intrinsic value, so it is not capable of affecting subsequent attitudes or intentions. The reason why consumers' perceived control has no influence may be due to the single function of AR virtual shoe-tryon function, the linear nature of the overall process, and the absence of multiple control methods. Consequently, it limits the consumers' perception of subjective control, which means that it cannot be considered an indicator in this research model or topic.
H5 is valid, indicating that the perceived responsiveness of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived aesthetics. H8 is valid, indicating that the perceived responsiveness of consumers in AR virtual shoe-try-on function will positively influence their attitudes toward the perceived playfulness. The validity of H5 and H8 means that the perceived responsiveness of consumers has a positive impact on consumers' perceptions of the intrinsic value of the AR virtual shoetry-on function. The perceived responsiveness of consumers reflects the human-computer communication response speed of the AR virtual shoe-try-on function [92], which directly impacts their experience. As opposed to perceived personalization, perceived responsiveness has a higher impact on aesthetics, indicating that there is a stronger connection between consumers' personal aesthetics and perceived responsiveness. In the case of the AR virtual shoe-try-on interface, user experience and color fusion, the higher the level of software design, the more it can affect consumers' aesthetic and influence them to have a positive attitude, preference and even use intention towards it. Customers may, among these attributes, pay greater attention to the response speed of the AR virtual shoe-try-on function. Through rapid feedback on the AR virtual shoe-try-on function and optimization of the user experience, a coherent interactive experience can be achieved, which is also an important aspect of aesthetics [93].

Theoretical Implications
Among the contributions of this study is suggesting how perceived interactivity (divided into perceived personalization, perceived control and perceived responsiveness) and intrinsic value (divided into aesthetics and perceived playfulness) affect consumers' willingness to continue using the AR virtual shoe-try-on function when they use the AR APP (the case of this study is the POZION APP). This study discusses the possibility of intuition and lays a foundation for further investigation. Based on the data analysis, both perceived interactivity and intrinsic value have an impact on consumers' attitude and their continuance intention to use the AR virtual shoe-try-on function. Perceived interactivity will influence consumers' attitudes and intentions through the intrinsic value. It is noteworthy that in the context of this study topic and model perceived control has no influence, while perceived personalization and perceived responsiveness have more influence on perceived playfulness and aesthetics, respectively.
