Understanding driver adoption of car navigation systems using the extended technology acceptance model

This study proposes an integrated research model for investigating driver adoption of car navigation systems. We consider the potential causal connections between core cognitive and psychological factors and driver intention to use these systems. We extracted possible factors that may significantly affect the perceived usability of car navigation systems from in-depth interviews with two groups of individuals: an expert group and a driver group. Data collected from N?=?1045 drivers via an online survey were analysed by structural equation modelling. The results showed that the service & display quality components of the systems were the most significant determinants of driver attitude and intention to use car navigation systems. Two other factors, namely attitude and perceived usefulness, also had impacts on driver intention. Moreover, both satisfaction and service & display quality were affected by perceived system reliability, while usefulness was affected by both perceived locational accuracy and satisfaction. Satisfaction also significantly affected perceived ease of use. In addition, we introduced new external variables to the technology acceptance model (TAM) and validated the causal connections proposed by the original TAM. The present study provides valuable insights into the core factors that significantly affect driver perspectives of and intention to use car navigation systems.

Determinants of academic use of the Internet: A structural equation model

The last decade of the 20th century brought radical changes in information and communication technology. Internet usage is being widely researched in the business world. However, the use of the Internet in academic settings in general and in vocational and technical establishment in particular is a neglected area. Successful use of the Internet is largely dependent upon the user's behaviour that, in turn, affects their attitudes. Even when remarkable opportunities exist for the deployment of technology, adverse attitude can inhibit use. Keeping this in mind, a survey of 166 academics of four technical and vocational colleges was conducted to study the attitudes of academics toward the use of the Internet. This study develops a model and validates two specific attitudinal variables--perceived usefulness and perceived ease of use--which are hypothesized to be fundamental determinants of use of the Internet. Adding two more variables--such as task characteristics and computer exposure--test the parsimony of the model further. A structural equation modelling technique is used to validate the model. The study confirmed that 79% of academics are using the Internet. Computer experience, perceived usefulness and perceived ease of use remain to be fundamental determinants of attitude formation. No other variables have been found to be significant.     

A Model of Green Acceptance and Intentions to Use Bike-Sharing: YouBike Users in Taiwan

With the emphasis on sustainability in transportation, bike-sharing systems are gaining popularity. This paper investigates the attitudes of users of a bike-sharing system with the aim of identifying their priorities, thus allowing local governments to focus their efforts most effectively on enhancing users’ intentions to use such systems. The relationships among green perceived usefulness (the extent to which individuals believe that a bike-sharing system will improve the environmental performance of some part of their life within a specific context), user attitude and perceived ease of use with green intentions, and the mediation effect of user attitude towards bike-sharing are explored. The focus of the study is on how to enhance green intentions via perceived usefulness, perceived ease of use and user attitude of the green technology acceptance model (green TAM) (Davis 1989). The two-step approach of structural equation modeling was applied to analyze the empirical results, which indicated that green perceived usefulness and user attitude have positive influences on the green intentions of 262 users and 262 non-users from ten sampled bike-sharing sites around the central administrative districts of Taipei. However, user attitude has the highest mediation effect on green intentions, and perceived ease of use does not have a significant effect on intentions for either users or non-users. Therefore, governmental institutions can strive to improve the attitudes of bike-sharing users and non-users, their green perceived usefulness, and perceived ease of use to strengthen their intentions to use this mode of sustainable transportation.

Using technology to alleviate poverty: use and acceptance of telecenters in rural India

The preponderance of poor people worldwide live in rural areas. Since they cannot afford, and are not educated sufficiently to take full advantage of contemporary knowledge-based technologies, alternative approaches are necessary. A major business model to do so involves setting up a rural telecenter that provides computer and internet technology as a shared model or highly subsidized. Despite the potential and availability of telecenters, research suggests that telecenters have low usage. In this research, we explore the reasons for the low usage of telecenters using a framework for use and acceptance of rural telecenters. The framework we use builds on prominent IT theories and has the following four dimensions: (a) perceived outcomes, (b) perceived effort, (c) social influence, and (d) facilitating factors. We use this framework to formulate six research questions. The study in general has the goal to identify reasons for low use of telecenters and test it with an exploratory study of information and communication technology users and non-users from rural India. Implications are discussed at the village and provider levels. Ramiro Montealegre is the accepting Associate Editor for this article. View all notes     

Understanding adolescents’ unfriending on Facebook by applying an extended theory of planned behaviour

ABSTRACT

Becoming friends on Facebook does not always guarantee long-term friendships as users have the possibility to unfriend people. This unfriending behaviour is frequently occurring and might have negative consequences for both parties. To gain insight into the factors influencing adolescents’ unfriending, the current study made use of an extended version of the theory of planned behaviour. To enrich the theoretical framework, we included antecedents related to adolescents’ friendship management on Facebook, namely their number of friends, their friendship acceptance threshold, and their degree of public communication. A cross-sectional survey was conducted among 1.117 adolescents. SEM analyses indicated that both subjective norm and attitude were related to behavioural intention, which in turn was related to adolescents’ unfriending behaviour. Perceived behavioural control was only associated with adolescents’ unfriending behaviour. Regarding the additional factors, the size of adolescents’ friend network was positively related to their confidence in the ability to unfriend people. Adolescents’ friendship acceptance threshold was negatively related to their attitude, whereas adolescents’ degree of public communication was positively associated with their perceived behavioural control and the experienced social pressure to unfriend.     

The study of perceived adverse effects of digital piracy and involvement: insights from adult computer users

In this study, we focus on two sets of expected negative consequences of engaging in digital piracy among the seldom studied adult computer users rather than student population. We delve into the role of perceived risk and moral intensity as drivers of consumers’ attitudes and behavioural intentions, and explore the rarely examined moderating effect of issue involvement on the relationship between the attitude and intention to pirate. The dominant attitude–behaviour theory is extended with an ethical decision-making theoretical perspective. The hypotheses are tested via mail survey data from a random sample of adult consumers using structural equations modelling. The results of this cross-sectional study show unfailing support for the relationships proposed in our model. Our findings suggest that, in addition to perceived risk, moral intensity (i.e. the expected consequences for others), has a particularly strong total effect on the intention to pirate, and that consumer involvement in illegally downloading files is a salient factor moderating the relationship between attitudes and behavioural intentions. Based on this pattern of results, we offer theoretical and practical implications.     

The respective roles of perceived usefulness and perceived fun in the acceptance of microcomputer technology

Abstract

This study examined the effects of two main factors affecting microcomputer technology acceptance: perceived usefulness and perceived fun. We examined whether users are motivated to accept a new technology due to its usefulness or fun. Results of this study suggest that perceived usefulness is more influential than perceived fun in determining whether to accept or reject microcomputer technology. We also examined the impact of computer anxiety on acceptance. Results showed that computer anxiety had both direct and indirect effects on user acceptance of microcomputer technology, through perceived usefulness and fun. We also found attitude (satisfaction) to be less influential than perceived usefulness and fun. Implications for the design and acceptance of microcomputer technology and future research are discussed.     

Promoting the integration of technology in teaching: An analysis of the factors that increase the intention to use technologies among Italian teachers

Background: The rapid spread of COVID-19 forced many countries to adopt severe containment measures, transferring all didactic activities into virtual environments. However, the integration of technology in teaching may present difficulties, especially in some countries, such as Italy. Objectives: The present study analyzed how the two main factors of the Technology Acceptance Model (TAM), namely perceived usefulness and perceived ease of use, combined with online teaching self-efficacy, were associated with the intention to use technology to teach. We posited a moderated moderation model in which perceived usefulness represented the main predictor, with self-efficacy and perceived ease of use as moderators of intention to use technology to teach. Method: The model was tested through multiple regressions, using the PROCESS macro on SPSS 26 with a sample of 178 upper secondary school teachers in Italy. Results and conclusions: Regressions showed that each variable significantly predicted the intention to use technology. In addition, a moderation effect of self-efficacy on the perceived usefulness of using technology was found for medium and high-level of perceived ease of use of technology. Implications: The present study provides targeted implications for distance education policy and practice to promote its adoption (or the blended modality) in Italian upper schools.     

The Investigation of E-Learning System Design Quality on Usage Intention

ABSTRACT

A well-designed product increases customer value and leads to repeat usage. However, studies on the impact of website quality on customer usage fail to distinguish website competence from website capability, ignoring that website quality performance has impacts on other website quality attributes. We gather data from 314 undergraduate students and apply partial least square method to examine the design quality mechanisms and other factors that influence users’ experience. Our results indicate that offering personalized products or services is an important enabler toward enhancing users’ attitude and usage intention. Particularly, for IS education in the format of e-learning, our results suggest firms developing textbook technology platforms primarily focus on creating superior quality designs leading to capabilities that enhance user customization. The customization experience will lead to better satisfaction via both perceived usefulness and perceived ease-of-use.     

Extended conceptualisation of perceived usefulness: empirical test in the context of information system use continuance

A technology or an information system provides value to its users. Technology Acceptance Model (TAM) successfully operationalised such value as the degree that a system can improve users' job performance. The proposed construct, perceived usefulness, has been proved to be the most important factor for technology adoption. However, many scholars have called for further theoretical development to enrich this critical construct but not much effort has been put forward (Bagozzi, R.P., 2007. The legacy of the technology acceptance model and a proposal for a paradigm shift. Journal of the Association for Information Systems, 8 (4), 244–254; Benbasat, I. and Barki, H., 2007. Quo vadis, TAM? Journal of the Association for Information Systems, 8 (4), 212–218). To respond to this call on deepening the conceptualisation of perceived usefulness, this article argues that system usefulness can be formulated beyond job performance improvement and explores several additional usefulness constructs based on well-established management concepts and human need theory. The information system (IS) use continuance model (Bhattacherjee, A., 2001. Understanding information systems continuance: An expectation-confirmation model. MIS Quarterly, 25 (3), 351–370) has been adopted as the theoretical foundation of this study because certain types of system usefulness can be recognised only in a use continuance stage. The empirical results of the research have validated most of the proposed constructs. Significant contributions to research and practice are identified and discussed.     

Understanding Perceived Trust to Reduce Regret

Trust is fundamental for promoting the use of online services, such as e‐commerce or e‐health. Understanding how users perceive trust online is a precondition to create trustworthy marketplaces. In this article, we present a domain‐independent general trust perception model that helps us to understand how users make online trust decisions and how we can help them in making the right decisions, which minimize future regret. We also present the results of a user study describing the weight that different factors in the model (e.g., security, look&feel, and privacy) have on perceived trust. The study identifies the existence of a positive correlation between the user's knowledge and the importance placed on factors such as security and privacy. This indicates that the impact factors as security and privacy have on perceived trust is higher in users with higher knowledge.     

Understanding Continuance Intention of Mobile Payment Services: An Empirical Study

Research on continued use of mobile payment services is scarce. To address part of this research gap, we examine a research model, derived from IT continuance, risk-trust, and affect-cognition literature. The results show that user satisfaction with mobile payment services has a substantive positive impact on continuance intention with such services; the disconfirmation of preadoption perceived usefulness about mobile payment services positively impacts user satisfaction and postadoption perceived usefulness; the disconfirmation of preadoption perceived risk about mobile payment services negatively impacts user satisfaction and positively impacts postadoption perceived risk; postadoption perceived usefulness is positively associated with continuance intention; user satisfaction positively impacts both institution-based trust in mobile payment technologies and trust beliefs in service providers; institution-based trust shows a positive impact on postadoption perceived usefulness and a negative impact on postadoption perceived risk.     

M‐payment service: Interplay of perceived risk,benefit, and trust in service adoption

This study aimed to examine the effects of perceived risk, perceived benefits, and trust on consumers’ intention to use mobile payment, or m‐payment. In addition, different effects of some demographic factors (e.g., income, age, education) on m‐payment usage were examined. The sample of 457 respondents was used to analyze the causal relationships between the variables and the mean differences of demographic factors in consumer intention to use m‐payment. The results supported the negative relationship between perceived risk, trust, and consumer intention to use m‐payment. A positive relationship between perceived benefits and trust was found. This study revealed that trust mediated consumer intention to use m‐payment. In individual differences of m‐payment adoption, education influenced the relationship between perceived risk and intention to use m‐payments as well as the relationship between trust and intention to use m‐payment. This study provided insights into consumer differences regarding m‐payment adoption and the mediating role of trust between perceived benefits, perceived risk, and intention to use m‐payment.     

Understanding information proactiveness and the content management system adoption in pre-implementation stage

The overall technology acceptance literature does not pay sufficient attention to the issue of the mandated use of systems as the traditional acceptance models (e.g. TAM) were originally built, tested, and validated by being applied to technologies that were mainly voluntary in nature, that is, the users had the choice of whether to use or not use the technology. Few have studied end users' proactive motivation to use information and attitude toward newly implemented technologies within organizational contexts, before end-users start using the technology or pre-implementation stage. This research proposes that information proactiveness has influences on the content management systems adoption beliefs such as perceived ease of use and perceived usefulness. The proposed model was empirically tested using the data collected from content management systems end-users. As theorized, information proactiveness was found to be a significant determinant of system users' perceived ease of use but not perceived usefulness in pre-implementation stage. Furthermore, perceived behavioral control was found to be a strong determinant of systems users' attitude. The study findings provide important insights on enhancing system users' adoption behavior in pre-implementation stage.     

Predicting adolescents’ use of social networking sites from an extended theory of planned behaviour perspective

The popularity of social networking sites (SNSs) among adolescents has grown exponentially, with little accompanying research to understand the influences on adolescent engagement with this technology. The current study tested the validity of an extended theory of planned behaviour model (TPB), incorporating the additions of group norm and self-esteem influences, to predict frequent SNS use. Adolescents (N = 160) completed measures assessing the standard TPB constructs of attitude, subjective norm, perceived behavioural control (PBC), and intention, as well as group norm and self-esteem. One week later, participants reported their SNS use during the previous week. Support was found for the standard TPB variables of attitude and PBC, as well as group norm, in predicting intentions to use SNS frequently, with intention, in turn, predicting behaviour. These findings provide an understanding of the factors influencing frequent engagement in what is emerging as a primary tool for adolescent socialisation.     

Does the technology acceptance model predict actual use? A systematic literature review

ContextThe technology acceptance model (TAM) was proposed in 1989 as a means of predicting technology usage. However, it is usually validated by using a measure of behavioural intention to use (BI) rather than actual usage.ObjectiveThis review examines the evidence that the TAM predicts actual usage using both subjective and objective measures of actual usage.MethodWe performed a systematic literature review based on a search of six digital libraries, along with vote-counting meta-analysis to analyse the overall results.ResultsThe search identified 79 relevant empirical studies in 73 articles. The results show that BI is likely to be correlated with actual usage. However, the TAM variables perceived ease of use (PEU) and perceived usefulness (PU) are less likely to be correlated with actual usage.ConclusionCare should be taken using the TAM outside the context in which it has been validated.     

Understanding the behavior of mobile data services consumers

Due to rapid advances in the Internet and wireless technologies, a ubiquitous computing world is becoming a reality in the form of mobile computing. At the center of this phenomenon is mobile data services which arise from the convergence of advanced mobile communication technologies with data services. Despite the rapid growth in mobile data services, research into consumers’ usage behavior is scarce. This study attempts to identify and empirically assess the factors that drive consumers’ acceptance of mobile data services. A research model based on the decomposed theory of planned behavior and incorporating factors that represent personal needs and motivations in using mobile data services is presented. The model is tested via an online survey of 811 consumers of four categories of mobile data services (i.e., communications, information content, entertainment, and commercial transactions) associated with different usage contexts. We found that attitude, social influence, media influence, perceived mobility, and perceived monetary value influence consumers’ intention to continue usage of mobile data services. In addition, perceived ease of use, perceived usefulness, and perceived enjoyment influence attitude toward continued usage of mobile data services. Finally, separate analysis of the different categories of mobile data services highlights the influence of individual usage context on consumers’ behavior.

The Effectiveness of Short Message Service for Communication With Concerns of Privacy Protection and Conflict Avoidance

Why would people use Short Message Service (SMS) to say something they would not say in person? There is a trend that SMS is becoming more and more popular because it facilitates more extended modes of communications. Using technology acceptance model, we hypothesize the attitude of SMS would be influenced by its perceived effectiveness for communications, perceived ease of use, and subjective norm. Besides the special aspects of communications, conflict avoidance and privacy protection will enforce the impact of perceived effectiveness of SMS for communication. We investigated 953 SMS users and the results support most of our hypotheses. Furthermore, our analyses also show there are differences between females and males on the influence mechanism behind their attitude towards SMS.
