BACKGROUND The concept of MyData emerged as a paradigm shift in personal data management and the process of seeking to transform the current organization-centered system. MyData enables the utilization of one’s own personal information that is scattered among various institutions as a system for data subjects to exercise rights of self-determination. OBJECTIVE We aimed to develop and demonstrate a MyData platform (MyHealthData) that allows data subjects to download and manage health-related personal data stored in various medical institutions. METHODS The platform consists of a mobile app for users, API (application program interface) for data conversion and exchange installed in the hospital information system (HIS), and a relay server connected to the blockchain to prove data integrity. User surveys were conducted to explore perceived usefulness, perceived ease of use, and satisfaction. RESULTS We provided four services to users through the platform developed in this study: inquiring about medical and health checkup records, health coaching, checking conditions of participation in clinical research, and claims, by using an app. A total of 1,228 participants signed for the service and the overall user satisfaction was high, especially with ‘inquire about medical and health checkup records.’ CONCLUSIONS MyData brings a user-centered paradigm in which data subjects can directly participate in the use of their own data. MyData will improve healthcare data interoperability, allowing it to be used not only in research areas but also in other areas by sharing and integrating various healthcare data.

Present study is an attempt to measure technology readiness of Indian customers towards self checkout service (SCS) through mobile app at retail stores at Hyderabad, India. Self-checkout services (SCS), a key offering of self service technology (SST), ‘is the technological enablement of customers to make payments and complete a checkout, after shopping, with little or no interaction with a service employee.’ Researchers also studied correlations between technology readiness, perceived usefulness, perceived ease of use, and likelihood to use SCS. For the purpose of the study TRI 2.0 developed by Parasuraman and Colby (2015) was used along with items of perceived usefulness and perceived ease of use, adapted from Davis (1989) , and items of ‘likelihood to use’ adapted from Bitner, Ostrom and Meuter (2002) . The findings of the study reveal that respondents’ technology readiness was moderate with respect to mobile based SCS. Significant positive correlations were found between: technology readiness and perceived ease of use, perceived ease of use and perceived usefulness, perceived ease of use and likelihood to use, perceived usefulness and likelihood to use. Further the respondents were categorised in to five technology segments as sceptics, explorers, pioneers, avoiders and hesitators.

Acceptance Model

This chapter identifies user satisfaction levels of eGovernment services. Technology Acceptance Model (TAM) deals with the prediction of the acceptability of an information system. TAM posits that perceived usefulness and perceived ease of use determine an individual's adoption of a system with intention to use serving as a mediator of actual system usage. In this chapter, a modified version of the TAM is proposed to predict the acceptability of eGovernment services and to identify the modifications, which must be brought to the system in order to make it acceptable to users. In the chapter, one of the most used eGovernment projects, e-school, is investigated according to TAM. An Internet-based survey questionnaire was applied to identify factors that influence users' satisfaction from one of the eGovernment services in Turkey. The sample was 30 teachers, who are working in public and private schools. A factor analysis was conducted on the questionnaire items, and a regression analysis, dependent on the factor analysis, was performed to determine and evaluate the effects of the factors on user satisfaction. The authors found that five main factors have significant affect on the satisfaction of users related to the e-School system. These factors are utilitarian ease of use, system usefulness, system content, system usability, and ease of use. The authors contributed to existing literature by adding a new construct, which refers to utilitarian ease of use.

This study investigated user satisfaction when a new interorganizational information system (green supply chain management system; GSCMS) was introduced to a supplier by a leader in the Taiwan electronic industry. GSCMS providers, according to the requirements of the supplier network leader, trained the representatives of suppliers. All suppliers of two sample vendors (manufacturers of electronic products) were surveyed. Five putative influencing factors were considered: perceived usefulness, perceived ease of use, training, computer anxiety, and computer self-efficacy. We find four factors significantly affect user satisfaction. The results show that the training provided by focal vendors will influence the satisfaction of users. Next, the anxiety and uncertainty experienced by users decreases when they acquire more knowledge about the operation of the new GSCMS. Finally, user satisfaction can be increased by designing the functions and interfaces of a GSCMS in accordance with the user perceptions of usefulness and ease of use, moreover, implications and suggestions are also discussed.

One of the major roles of governments is to create a favorable business environment for fostering entrepreneurial activities, including good infrastructure and a culture that encourages the adoption of technologies. In such a policy context, the Greek National Electronic Public Procurement System (ESIDIS) was developed. The use of ESIDIS is mandatory for the employees, and its success depends on users' satisfaction. The chapter investigates the factors influencing employees' satisfaction when using the system. Perceived usefulness, perceived ease-of-use, perceived risk, and willingness to learn were investigated using empirical research. Structural equation modeling was used for the analysis of the data. Perceived usefulness has the most significant role in determining user satisfaction while risks importance is diminished when users understand the usefulness of the system for their job performance. Managers and policymakers should take these factors into consideration in order to improve users' satisfaction and consequently maximize the added value of the system for the entrepreneurs.

The advent of smartphones revolutionized and took the market to a new level. Now a days, majority of internet users spend their maximum time on smartphones, specifically on mobile apps. The emergence of numerous apps in smartphones with games features has brought about a different trend, mobile app gamification. The emerging popularity of smartphone technologies and their mobile apps have led various companies to engage their consumers with mobile apps, specifically through gamification. Therefore, companies gain consumers attention integrate their mobile marketing into their overall marketing strategy. This study explores the domain of consumer engagement and their intentions through the gamification of mobile apps. The research focuses on how mobile app gamification drives consumer engagement and their intentions drawing upon SDT and TAM. Using survey method data collected from 270 respondents, data analysis was done with structure equation modeling (SEM). The findings assert that various features of gamification of mobile apps (perceived ease of use, perceived usefulness and enjoyment) have a significant influence on consumer engagement. However, convenience was unexpectedly found not to be significantly associated with consumer engagement. Additionally, consumer engagement was found to be associated to smartphone user's intentions to use gamification of mobile apps. The results of present study have theoretical and practical implications.

Mobile information and communication technology changed how people and businesses can benefit from government public services at any time and from anyplace. The success or failure of mobile government services is becoming more dependent on satisfying the needs and the expectations of both citizens and business organizations. This paper reviews and analyses some existing empirical studies that examine m-Government acceptance in some developing countries. Then, a new integrated conceptual model for examining some important key factors that may affect m-Government acceptance in Jordan from user perspective was proposed.  An empirical test was conducted using a questionnaire to explore the effect of the following factors: Trust in mobile channel, trust in government, perceived usefulness, perceived ease of use, relative advantage, compatibility, complexity, service quality and user satisfaction on the behavioural intention to use m-Government applications. Finally, justification of the proposed integrated model and formulation of the associated hypotheses was conducted.

Purpose The purpose of this paper is to extend significantly the technology acceptance model (TAM) of Davis to design an extended TAM model to be used in the evaluation and assessment of e-information services for information research such as e-library services. The present TAM extension is based on two variables of behavioral intention: the perceived ease of use and perceived usefulness of a system. Furthermore, the user satisfaction, free access, information architecture, content richness, policies and rules, publishers’ quality, system self-efficacy and task technology fit were incorporated into the TAM to extend it with other factors theoretically motivated and would be of interest more generally. Design/methodology/approach The researcher adopted an experimental approach-based comparison between an experimental group (107 researchers) using an electronic information service (the e-library service of the university) and a control group (107 researchers) not registered in this e-information service of the university. Findings The researcher used the effect size values based t-test independent samples at the 0.05 level to adapt the structural model equation to the experimental sample. Principal results show that the behavioral intention was influenced significantly by user satisfaction. The perceived usefulness of the e-library services was influenced significantly by the perceived ease of use, information architecture, content richness, free access, publishers’ quality, task-technology fit and e-library service self-efficacy. Originality/value This paper is useful in advancing a framework for the evaluation and assessment of the electronic information service used for information research and exploring users’ attitudes toward using that service.

User satisfaction with information system quality has long been a substantial topic in the literature of information system (IS). Based on the key constructs of IS success model (including system quality and information quality) and technology acceptance model (including perceived ease of use and perceived usefulness), this paper builds and validates a theoretical framework to explain user satisfaction with information system quality. A survey study with AMOS-SEM analysis of 363 users of management information systems in 9 hospitals in HCMC, Vietnam showed that 12 of 14 hypotheses were empirically supported. The findings affirmed the direct influence of system quality, information quality and top management support on perceived ease of use, perceived usefulness and trust, and then on user satisfaction. The results also reinforced the impact of perceived ease of use on perceived usefulness, and the joint influence of perceived usefulness and trust on user satisfaction. The paper is among the first studies, in the healthcare sector, to empirically identify both information system quality and top management support in predicting user acceptance of and satisfaction with information system implementation in organizational settings. The theoretical and managerial implications of the paper were derived.
