User acceptance of media tablets: An empirical examination of perceived value

Media tablets have been one of the most innovative and popular mobile devices with the rapid development of mobile computing technology. The purpose of this study is to offer a clear understanding of the overall adoption processes by starting from the characteristics of a media tablet to adoption intention via perceived value. This study investigates the relationships between the value of media tablet (e.g., usefulness, enjoyment, social image, and risk) and the product characteristics (e.g., design, functionality, contents, brand, and price). Perceived benefits including perceived usefulness, perceived enjoyment, and social image seem to have a greater impact than the level of perceived sacrifice on perceived value. Perceived usefulness is the strongest factor determining adoption intention through perceived value. An innovative design affects social image, and brand name positively affects both perceived usefulness and social image. Functionality and content have a positive influence on both perceived usefulness and enjoyment. Price positively affects perceived risk. This research also finds that smartphone experience moderates the effect of perceived usefulness on perceived value, and personal innovativeness offsets the negative effect of perceived risk on perceived value as a moderator. These findings contribute a number of implications for academia and practitioners.     

Modeling subjectively perceived annoyance of H.264/AVC video as a function of perceived artifact strength

This paper is concerned with the subjective perception of video coding artifacts in H.264/AVC encoded and decoded video. Our objective is to model the perceived annoyance of such low bit rate video sequences as a function of perceived artifact strength. We introduce a new method for determining this function and apply it to the data from two psychophysical experiments. Both experiments produced numerical judgments of the subjectively perceived annoyance of artifact combinations and the perceived strength of the respective coding artifacts. Our method produces a discrete multi-dimensional representation of the relationships in the data from which the function relating annoyance to artifact strength is derived. The method is applied to the data of the first experiment and the resulting function is shown to describe the data from the second experiment as well.     

Impact of gaming habits on motivation to attain gaming goals,perceived price fairness,and online gamer loyalty: Perspective of consistency principle

Online games are popular electronic commerce applications that have a business model of selling gaming items to gamers. Such a business model helps gamers attain gaming goals while cultivating their gaming habits. Gaming habits can lead gamers to play games automatically, indicating their impact on gamers. However, little is known about how gaming habits affect gamers’ perceptions of the prices of the gaming items, goal-attaining motivation, and online gamer loyalty. Grounded in the consistency principle, we construct a framework to explain how gaming habits impact motivation to attain gaming goals, perceived price fairness, and online gamer loyalty. We collected 5,144 responses from online gamers and used structural equation modelling to test the research model. We found that gaming habits are positively related to motivation to attain gaming goals and perceived price fairness, which are further positively related to online gamer loyalty. Ours is the first study using the perspective of the consistency principle to examine the mechanism underlying the impact of gaming habits on online gamer loyalty. Our findings provide novel insights for electronic commerce managers that they could focus on enhancing perceived price fairness and motivation to attain gaming goals, thus establishing a loyal user base. Such findings could also apply to interactive hedonic systems, indicating their potential academic impact.     

Perceived value and continuance intention in mobile government service in China

Drawing on the value-based adoption model (VAM), a research model of mobile government (m-government) continuance usage behavior is developed. Data collected from a survey of 246 users of an m-government application in China are used to test the research hypotheses. Our results indicate that mobility, localizability, and personalization are positively associated with perceived value, which in turn, is positively associated with continuance intention. Our results show that perceived value partially mediates the relationships between mobility, personalization, and localizability (but not security) with continuance intention. Further, compatibility positively moderates the relationship between perceived value and mobility, localizability, and security (but not personalization), and between perceived value and continuance intention. Our results suggest that there is a tradeoff between personalization and security (analogous to personalization-privacy paradox where users are torn between their desire for personalization and their instinct to protect their privacy). Implications for research and practice are discussed.     

Who finds value in news comment communities? An analysis of the influence of individual user,perceived news site quality,and site type factors

User commenting forums are a ubiquitous interactive feature offered by news organizations. Despite their popularity, research has generally failed to investigate extent to which news readers themselves find any redeeming value in news comment communities and, therein, the factors that serve as antecedents to such value perceptions. In light of this gap in the literature, this study set out to determine the factors associated with news community value. Using a sample of over 500 news consumers, we explored the impact of individual user, site quality, and site type factors. The results suggested that perceived news community value was highest among those with high levels of self-efficacy and those who use the Internet for civic purposes. The data indicated also that value perceptions were highest for those news sites that were understood to be interactive and aesthetically pleasing. Finally, perceived news community value was highest on sites that were both non-traditional and non-partisan in nature.     

Untangling the effect of cognitive trust and perceived value on health-related information seeking,sharing and psychological well-being: Motivations sought perspective

Previous literature has documented that mobile application utilization increased exponentially throughout the ongoing COVID-19 epidemic. To comprehend the possible antecedents of individuals’ psychological well-being, this research invokes motivation theory and associated literature on perceived assessment (cognitive trust, perceived value, and perceived threat) to comprehensively investigate the determinants of factors influencing mobile app users’ health-related information behaviors and psychological outcomes. Data were gathered collected from 898 users of mobile apps, and this article adopted structural equation modeling (SEM) to evaluate the hypothesis generation model. Obtained findings demonstrated that cognitive trust and perceived value positively impacted seeking and sharing health-related information, which subsequently benefited individuals’ psychological well-being during the public health crisis. Furthermore, perceived threat exerted a negative impact on seeking and sharing health-related information. These results contribute to existing studies on psychological well-being by broadening the antecedence domain of information practices and revealing the underlying psychological mechanism behind this dynamic process. This study could also benefit practitioners by providing insights into embedded system and mobile app development, which would play a pivotal role in enhancing user experiences that optimize psychological well-being.     

The effect of platform characteristics on the adoption of smart speakers: Empirical evidence in South Korea

The emerging market for smart speakers is growing rapidly. Unlike conventional information technology (IT) devices, smart speakers are becoming a major platform that access many types of information through a voice interface. This study examines the factors related to the adoption of smart speakers from the platform perspective. More specifically, our study investigated how the product related characteristics (e.g., functionality, design, brand, and price), platform related characteristics (e.g., perceived service availability, perceived network size, perceived complementarity) and privacy concerns affect the perceived value and intentions to adopt a smart speaker. The results indicate that platform related variables have a bigger impact on the customer adoption of the smart speaker, whereas product related variables, such as functionality, have less of an impact.     

What drives purchase intention on Airbnb? Perspectives of consumer reviews,information quality,and media richness

The owners of idle assets and their potential users create economic benefits through providing or sharing idle assets or skills, and this process has been formalized and monetized at large scales by companies such as Uber, Airbnb, USpace and others. This research seeks to understand the factors affecting the purchase intention on Airbnb users in terms of five key factors: rating, rating volume, review, information quality, and media richness. ANOVA and path analysis are used to test the relationships of these factors with perceived value, satisfaction and purchase intention. Results indicate that perceived value and satisfaction are key determinants of intention to buy, while rating volume, review, information quality, and media richness are important precursors. In addition, gender and usage experiences with Airbnb are also used to classify the sample to assess the difference between each classification. The results of this study can provide a useful reference to researchers and firms and individuals working in the sharing economy.     

Business undergraduates’ perceived use outcomes of Moodle in a blended learning environment: The roles of usability factors and external support

This study was designed to explore the effects or roles of usability factors (i.e., perceived ease of use, perceived usefulness, and satisfaction) and external support (i.e., teacher and peer support) on undergraduates’ use outcomes of Moodle in a blended learning environment. The research hypotheses derived from relevant constructs taken from the technology acceptance model, information systems continuance model, and the theory of reasoned action. The study’s dependent variable is use outcomes, which was conceptualized with factors such as academic performance, perceived learning assistance, and perceived impacts on learning. We conducted a cross-sectional survey and collected data from 126 undergraduate students attending a university in the Maritime region of Canada. The partial least squares technique was used to test the hypothesized relationships in the proposed research model. We found that usability factors have positive effects on students’ use outcomes; contrarily to predictions teacher and peer support did not. The findings of the study offer useful insights that can help HE administrators gain an understanding of antecedent factors likely to enhance students’ use outcomes of Moodle.     

Influencing factors on risk perception of IoT-based home energy management services

This study examines factors influencing the risk perception of Internet of Things (IoT) services in the home energy management sector. We focus on investigating the effects of the various types of perceived risks and individuals’ propensities on the overall risk perception of the IoT services and explore some demographic variables. The perceived risks include perceived financial risk, perceived performance risk, perceived security/privacy risk, and perceived electromagnetic radiation (EMR) risk. The individuals’ propensities include the sensitivity to electricity price changes, environmental destruction, and new technology acceptance. As a result, this study confirms the existence of various influencing factors in the risk perception of the IoT-based home energy management services. Perceived EMR risk is the most influential one among the various types of perceived risks of the services, followed by perceived performance risk and perceived security/privacy risk. In general, experts point out cybersecurity threats as a weakness of ICT services, but users are more likely to have fear of the EMR. Moreover, sensitivity to electricity price changes and sensitivity to new technology acceptance are significant factors. This study has a significance in that we explore various factors affecting the risk perception of IoT services in the energy management sector in detail and comprehensively. Particularly, we discuss not only perceptions about the IoT services, but also individuals’ propensities. This work may contribute not only to studies on perceived risk and technology acceptance but also to stakeholders trying to market the IoT services to consumers.     

Modeling the user acceptance of long-term evolution (LTE) services

With an integrated framework, this paper aims to analyze user perception and acceptance toward long-term evolution (LTE) services, focusing on factors that may influence the intention to use. We conducted a web-based survey of 1,192 users to test our research model. We employed structural equation modeling (SEM) as the analysis method. The results of the integrated model analysis indicate that system satisfaction is a core determinant of intention to use LTE services. The model also found that other factors, including perceived usefulness and system and service quality, significantly affect intention to use these services. In addition, both perceived adaptivity and processing speed significantly influence perceived usefulness and service quality, respectively. These factors also play key roles in determining users’ attitudes. This paper is of value to researchers and engineers designing and improving LTE services for use via mobile phones.     

The underlying factors of the perceived usefulness of using smart wearable devices for disaster applications

Smart wearable devices offer much potential to assist citizens in disasters. To the general public, however, using these devices for disaster applications is still a novel concept. In disasters, most people are reluctant to rely on unfamiliar technologies. Thus, for these devices to become truly useful in disasters, it is important to understand factors that affect their acceptance by the public. Previous studies show that perceived usefulness is a clear antecedent of people’s acceptance of smart wearable devices. However, the underlying factors that affect perceived usefulness itself are not clearly known. Thus, the aim of this study is to fill this gap, and by doing so, to derive some practical implications for solution developers and governments.This study used structural equation modelling to analyse survey data collected from 647 respondents in Japan. We found that the respondents’ perceived usefulness of the current applications of smart wearable devices was a strong predictor of their perceived usefulness of using these devices for disaster applications. Although indirect factors such as the ownership of ICT gadgets and the usage of social media also had some influences, most of their effects were mediated through increasing the respondents’ perceived usefulness of the current applications. In other words, through appreciating the functions of the current applications of smart wearable devices, people can visualise the usefulness of these devices in disaster situations. That being said, we found that in parallel, people also had concerns on the privacy issues of these devices. These findings shed light on the promotion and development of this fast growing technology for disaster applications.

Should I scan my face? The influence of perceived value and trust on Chinese users’ intention to use facial recognition payment

While China has seen the widespread adoption of facial recognition payment, concerns over the potential risks impede the further growth of user acceptance. Drawing on the perspectives of perceived value and trust, we developed a research model to explore how the Chinese users’ trade-off between perceived benefits (perceived convenience and perceived novelty) and perceived risks (perceived privacy risk and perceived financial risk) influences their usage intention. Based on survey data from 1,200 Chinese mobile payment users, this study uses structural equation modeling to examine the hypotheses. Our results show that perceived convenience positively influences perceived value, while privacy risk and financial risk negatively influence perceived value and trust. Although perceived novelty has no significant effect on perceived value and trust, perceived value positively influences trust, and both of them have a positive effect on the intention to use. Furthermore, our moderation analysis indicates that the influence of perceived value on the intention to use is stronger among users who consider facial information to be more sensitive. The theoretical implications for research as well as the practical implications for practitioners are also discussed.     

Defect visibility and content importance: effects on perceived impairment

In this paper, we describe the results of a series of psychophysical experiments that investigated the relationships among defect visibility, content importance, and perceived impairment in digital video. Various types of controlled defects were inserted into normal video and shown to our test subjects. The defects varied in their strength, location, appearance, size, and duration. We measured three specific subjective quantities: the defect detection probabilities, the perceived impairment, and the content importance. Impairment was found to be tightly related to defect visibility but only weakly related to content importance.     

The perceived importance of technical competence to projectmanagers in the defense acquisition community

Numerous studies have identified attributes which are associated with effective project managers. One of the more frequently cited attributes is technical competence. This study surveyed 228 project managers from the government sector of the defense aerospace community to determine the importance of technical competence to project managers. More importantly, this study examined the influence of several personal and situational factors on the perceived importance of technical competence. The factors included: the experience level of the project manager, the amount of technical education completed by the project manager, the level of technology employed in the project, the phase of the project, and the caliber of the project team. This study determined the perceived importance of technical competence did not vary by level of experience, though project managers who possessed more technical education perceived technical competence to be more important. With regard to the situational factors, the level of technology did not influence the perceived importance of technical competence. However, technical competence was perceived to be more important during earlier phases of the acquisition process. Further, technical competence was perceived to be more important for managers of extremely good teams and mediocre teams than it was to managers of reasonably good teams     

Technology Acceptance Model for the Use of Tablet PCs

Tablet personal computers (tablet PCs) are popular electronic devices worldwide. They influence many aspects of our social lives. Compared with laptop computers, tablet PCs feature characteristics including enhanced portability and display quality. The purposes of this study were to examine users’ attitudes toward tablet personal computers and identify the effects of external factors. This study extended the technology acceptance model and used perceived mobility and viewing experience as the external variables in the proposed model. This study used a web-based survey of 511 participants and found that perceived usefulness and perceived ease of use were key determinants of attitude toward tablet personal computers. Also, the perceived ease of use and usefulness of tablet PCs were significantly enhanced by perceived mobility and viewing experience. In addition, all traditional relationships from the origin technology acceptance model were supported. Lastly, both implications of the study and areas of future research are discussed.     

A novel monitoring architecture for media services adaptation based on network QoS to perceived QoS mapping

One of the future visions of multimedia networking is the provision of multimedia content at a variety of quality and price levels. Of the many approaches to this issue, one of the most predominant techniques is the concept of Perceived Quality of Service (PQoS), which extends the traditional engineering-based QoS concept to the perceptual satisfaction that the user receives from the reception of multimedia content. In this context, PQoS monitoring is becoming crucial to media service providers (SPs) for providing not only quantified PQoS-based services, but also service assurance based on multimedia content adaptation across heterogeneous networks. This work proposes a novel cross-layer monitoring architecture that utilizes a new Network QoS (NQoS) to PQoS mapping framework at the application level. The resulting QoS monitoring should allow the content delivery system to take sophisticated actions for real time media content adaptation, and aims to provide perceived service performance verification with respect to the QoS guarantees that have been specified in contractual agreements between providers and end-users. A subsequent performance evaluation of the proposed model conducted using a real test-bed environment demonstrates both the accuracy and feasibility of the network level measurements, the NQoS to PQoS mapping and the overall feasibility of the proposed end-to-end monitoring solution.

To shop or not: Understanding Chinese consumers’ live-stream shopping intentions from the perspectives of uses and gratifications,perceived network size,perceptions of digital celebrities,and shopping orientations

Live-stream shopping is experiencing unprecedented growth. However, research in live-stream commerce is in its infancy. The current study integrates uses and gratifications, perceived network size, perceptions of digital celebrities, and experience-focused shopping orientation to clarify motivations for live-stream shopping. Accordingly, the current study used a questionnaire to collect data from 339 Chinese consumers and structural equation modeling to analyze data in AMOS 24. In this study, individuals were motivated by gratifications that were (1) hedonic (perceived enjoyment), (2) utilitarian (self-presentation), and (3) social (social presence and interaction). Moreover, perceived network size significantly predicted perceived enjoyment, social interaction, social presence, and utility. In addition, experience-focused shopping orientation mediated the relationships among perceived enjoyment, self-presentation, social interaction, and live-stream shopping intentions. Finally, the mediating roles of the perceptions of digital celebrities in the relationships of perceived network size with perceived utility, perceived engagement, social interaction, social presence, and self-presentation were confirmed.
